  • [Title] Immunoproliferative small intestinal disease versus colonic monoblastic sarcoma in a 2-year-old boy.
  • The authors present a case of colonic monoblastic sarcoma, previously treated for other digestive abnormalities (malabsorbtion, Hirschprung's disease).
  • Important similitudes with immunoproliferative small intestinal disease (IPSID) lymphoma were demonstrated for this patient (male, 2-year-old).
  • Some particularities of this case are the young age and the extremely rapid development of the malignant disease in a patient with no previous signs of acute non-lymphoblastic leukemia.
  • The initial diagnosis was of malabsorbtion syndrome, based on the clinical exam at presentation, and then the patient was thought to have a form of Hirschprung's disease, due to a functional intestinal disorder (slow transit).
  • After the necropsy, pathologists diagnosed an immunoproliferative small intestinal disease, and four years later, they performed a more appropriate pathological exam, which explained better clinical symptoms associated to this complex case.

  • The complexing abilities of alpha-, beta-, or gamma-CD with six kinds of aliphatic acetate esters were compared. alpha-CD formed the highest numbers of complexes with all of the esters.
  • Among our samples of freeze-dried pear juice containing dissolved alpha-, beta-, or gamma-CD, the juice with alpha-CD retained the greatest amount of esters.
  • These data demonstrate that alpha-CD is an effective material with which to prepare powdered pear flavor materials.
  • The nuclear Overhauser effect, measured by (1)H NMR spectra, of an alpha-CD-butyl acetate or alpha-CD-hexyl acetate complex showed that these esters were included in the alpha-CD cavity.

  • [Title] Influence of poly(ethylene glycol)-alpha-cyclodextrin complexes on stabilization and transdermal permeation of ascorbic acid.
  • The present study was conducted to investigate the effect of poly(ethylene glycol)-alpha-cyclodextrin (alpha-CD) complexes on stabilization and cutaneous permeation of ascorbic acid from specially prepared transdermal patches.
  • Poly(ethylene glycol) citrate (6-armPEG) and its inclusion complex with alpha-CD were prepared and used for preparation of the transdermal patches.
  • The influence of drug release of alpha-CD and two types of its PEG complexes (as the novel permeation enhancers) was tested.
  • The 6-armPEG-alpha-CD complex consisting of a PEG-citric acid ester at a concentration of 0.08-0.1% (w/v) is a suitable stabilizer for ascorbic acid during UV assay.
  • The release studies showed that the type of enhancer is important in diffusion of the drug across membrane.
  • Furthermore, the diffusion of ascorbic acid was considerably enhanced in the presence of 6-armPEG-alpha-CD complex.
  • Inclusion complexes of 6-armPEG with alpha-CD at a concentration of 0.08-0.1% (w/v) is a suitable stabilizer for UV method of assay.
  • The present data suggest that 6-armPEG-alpha-CD complex is also useful in enhancing the release of ascorbic acid from the acrylic type pressure sensitive adhesives.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The effect of hydroxypropyl-alpha-cyclodextrin (HP-alpha-CD) complexation on in vitro pulmonary deposition of a cyclic peptide cyclosporin A (CsA) was studied.
  • In addition, the effect of storage (32 days, 40 degrees C, 75% RH) on CsA/HP-alpha-CD complexes was studied.
  • Solid CsA/HP-alpha-CD complexes were prepared by freeze drying.
  • Three inhalation formulations were prepared: CsA/lactose reference formulation (LF) (drug:carrier 1:364, w/w), CsA/HP-alpha-CD complex formulation (CDF) (drug:CD 1:269, w/w) and CsA/HP-alpha-CD complex/lactose formulation (CDLF) (complex:carrier 100:114, w/w).
  • When exposed to moisture (storage in a permeable polystyrene tube), the RF% values of CsA from formulations containing CsA/HP-alpha-CD complexes were lower than before the storage.
  • In conclusion, an acceptable RF% value of a peptide CsA from freeze-dried, simply micronized CsA/HP-alpha-CD complex powder was achieved before and after storage in the DPI.

  • [Title] Infection-associated lymphomas derived from marginal zone B cells: a model of antigen-driven lymphoproliferation.
  • Non-Hodgkin lymphomas develop from nodal and extranodal lymphoid tissues.
  • A distinct subset of extranodal lymphomas arising from B cells of the marginal zone (MZ) of mucosa-associated lymphoid tissue (MALT) or spleen has been individualized.
  • Growing evidence indicates that MZ lymphomas are associated with chronic antigenic stimulation by microbial pathogens and/or autoantigens.
  • The list of microbial species associated with MZ lymphoproliferations has grown longer with molecular investigations and now comprises at least 5 distinct members: H. pylori, C. jejuni, B. burgdorferi, C. psittaci, and hepatitis C virus (HCV), which have been associated with gastric lymphoma, immunoproliferative small intestinal disease, cutaneous lymphoma, ocular lymphoma, and spleen lymphoma, respectively.

  • ITC experiments have been employed to evaluate the stoichiometry of interaction (N), affinity constants (K), and thermodynamic parameter variation associated with complexation between (+)-UA and alpha-, beta-, HP-beta-, SBE-beta-, and gamma-CD.
  • It was shown that (+)-UA did not interact with alpha-CD and tended to interact more favorably with gamma-CD (K = 1030 M(-1), DeltaG = -17.18 kJ x mol(-1)) than beta-CD (K = 153 M(-1), DeltaG = -12.46 kJ x mol(-1)) forming 1:1 complexes.
  • Analysis of the thermodynamic data suggested that van der Waals forces and hydrogen bonds were responsible for the formation of complexes with a predominance of van der Waals forces.

  • [Title] Effect of guest hydrophobicity on water sorption behavior of oligomer/alpha-cyclodextrin inclusion complexes.
  • Cyclomaltohexaose (alpha-cyclodextrin, alpha-CD) can form inclusion complexes (ICs) with polymer molecules in the columnar crystal structure in which alpha-CD molecules stack to form a molecular tube.
  • Complementary water vapor sorption and wide-angle X-ray diffractomery (WAXD) were performed on oligomer/alpha-CD ICs to determine their structures and stabilities.
  • Sorption isotherms for PEG/alpha-CD IC are similar to those obtained for pure alpha-CD and PEG, suggesting the presence of dethreaded PEG in the sample.
  • WAXD collected before and after water vapor sorption of PEG/alpha-CD IC indicated a partial conversion from columnar to cage crystal structure, the thermodynamically preferred structure for pure alpha-CD, due to dethreading of PEG.
  • This behavior does not occur for HTC/alpha-CD IC.

  • New [2]- and [3]pseudorotaxanes containing alpha-cyclodextrin (alpha-CDs) molecules as rotors and alkyl pyridinium derivatives as axles were prepared by a slipping process.
  • The methyl group at the 2-position of the pyridinium moiety at the end of each axle molecule was found to control the rates of threading of the alpha-CD onto the axle molecules. alpha-CD can approach axle molecules from a particular direction to form inclusion complexes.
  • Axle molecules that contain a 2-methylpyridinium moiety at one end and a bulky stopper at the other end can regulate the direction of approach to give a [2]pseudorotaxane such as 2 b-alpha-CD.
  • A [3]pseudorotaxane in which two alpha-CD molecules are arranged facing in the same direction at two stations of the tetracationic axle molecule was also obtained.

  • The second tautomer is detected as a small shoulder in the blue side of the fluorescence peak and has a lifetime of 5.40 ns.
  • As the cavity size decreases in the order gamma-CD to beta-CD to alpha-CD, the cavity is more hydrophobic, which is reflected in an intensity decrease of the absorbance of the DZ tautomer and a red shift in its fluorescence peak.
  • In gamma-CD, the probe is located near the secondary rim of the CD annulus, whereas in alpha-CD, the probe is completely sequestered between two CDs, and the hydrophobicity is close to that observed in cyclohexane.

  • Because the formation constants of I3- with CD decrease in the order alpha-CD>beta-CD>gamma-CD, alpha-CD was most detectable by the method.
  • Detection limits were 1.0 micromol L(-1) for alpha-CD, 65 micromol L(-1) for monoG1-beta-CD, 100 micromol L(-1) for beta-CD, and 200 micromol L(-1) for gamma-CD.

  • The coelution of PQ and QC when alpha-CD was used as buffer additive can be explained by their comparable stabilities of the inclusion complex formed, while significant differences in the complexation stabilities of the drugs with beta-CD is responsible for their separation.

  • In this study, the antiviral activity of a RBV/alpha-cyclodextrin complex has been evaluated in vivo using the above model.
  • CBA/ca mice were treated by intraperitoneal injection of free ribavirin (40 mg/kg) or a RBV/alpha-cyclodextrin complex (molar ratio 1:3).
  • In contrast, mortality rates of 80% and 40%, respectively, were observed in RBV and RBV/alpha-CD-treated mice (p<0.05 and p=0.06 for distilled water and RBV, respectively).
  • This data shows that RBV complexation with alpha-cyclodextrin can increase the antiviral activity of ribavirin in a measles virus encephalitis model in mice.

  • [reaction: see text] Skeleton-modified cyclodextrin (CD) derivatives, in which an alpha-(1,4)-glucosidic bond is converted into a beta-(1,4)-glucosidic bond, were conveniently synthesized by cleavage of a single glucosidic bond in permethylated and 2,6-di-O-methylated alpha- and beta-CDs and subsequent recyclization via the trichloroacetoimidate intermediates.
  • The selective cleavage of an alpha-(1,4)-glucosidic bond of permethylated alpha- and beta-CDs was accomplished by stirring in 30% aq HClO(4) at 25 degrees C to give the corresponding maltohexaose and maltoheptaose derivatives, respectively.
  • The cleavage of a glucosidic bond of hexakis(3-O-benzyl-2,6-di-O-methyl)-alpha-CD was successfully carried out in a mixed 60% aq HClO(4) and 1,4-dioxane solution (1:20).
  • On the other hand, the beta-(1,4)-type permethylated alpha-CD derivative 4a exhibited lower inclusion ability toward sodium p- and m-nitrobenzoates than the parent permethylated alpha-CD.
  • On the other hand, host molecules 4a and 4b showed para-isomer selectivity toward sodium nitrophenoxide guests, indicating that the inclusion selectivity was remarkably influenced by the guest hydrophilic groups. (1)H NMR studies on complexes of those beta-(1,4)-type CD derivatives with p- and m-nitrobenzoates and p- and m-nitrophenolates were carried out to estimate their structures.

  • [Title] Non-covalent inclusion of ferulic acid with alpha-cyclodextrin improves photo-stability and delivery: NMR and modeling studies.
  • We prepared the inclusion complex of FA with alpha-cyclodextrin by co-precipitation from an aqueous solution, and used (1)H NMR and molecular dynamics to investigate the most probable structure of the inclusion complex.
  • In rotating frame nuclear Overhouser effect spectroscopy (ROESY) experiments FA penetrated the alpha-CD hydrophobic cavity with the alpha,beta-unsaturated part of the molecule and some of its aromatic skeleton.
  • In proton chemical shift measurements of FA and alpha-cyclodextrins we determined the stoichiometry of the association complex (1:1) by Job's method, and its stability constant (K(1:1) 1162+/-140 M(-1)) and described the molecular dynamics of the complex on the basis of theoretical studies.
  • Encapsulation with alpha-cyclodextrin improves (i) the chemical stability of FA against UVB stress (10 MED [Minimal Erythemal Dose: 1 MED=25 mJ/cm(2) for skin phototype II: 30]), since no degradation products are formed after irradiation, and (ii) the bioavailability of FA on the skin, slowing its delivery (Strainer cell model).

  • [Title] Complexation behavior of alpha-, beta-, and gamma-cyclodextrin in modulating and constructing polymer networks.
  • A systematic study of the host-guest complexation by alpha-, beta-, and gamma-cyclodextrin (CD) in either the free state or as substituents of poly(acrylic acid) (PAA) with the hydrophobic n-octadecyl groups, C18, substituted onto PAA (HMPAA) and its effect on polymer aggregation and network formation is reported.
  • Free alpha-CD, beta-CD, and gamma-CD mask hydrophobic associations between the C18 substituent of HMPAA in aqueous solution and form host-guest complexes with a 1:1 or CD:C18 substituent stoichiometry at 0.5 wt % polymer concentration.
  • For alpha-CD this host-guest stoichiometry changes to 2:1 or 2alpha-CD:C18 at > or =1 wt % polymer concentrations but not for beta-CD and gamma-CD.
  • Upon addition of sodium dodecyl sulfate, SDS (SDS:CD = 1:1), the hydrophobic associations between C18 diminished by alpha-CD masking were fully restored, were only partly restored in the case of beta-CD, and not restored for gamma-CD.
  • When alpha- and beta-CD substituted PAA (alpha-CDPAA and beta-CDPAA) were mixed with HMPAA polymer, networks formed.
  • The alpha-CD substituents of alpha-CDPAA also formed 1:1 or alpha-CD:C18 stoichiometry host-guest complexes with some indication of the formation of 2:1 or 2alpha-CD:C18 stoichiometry host-guest complexes at polymer concentrations > or =1 wt %.
  • The polymer networks formed by beta-CDPAA with HMPAA are less viscous than those formed by alpha-CDPAA, for which shear-thickening occurs at polymer concentrations > or =2 wt %.
  • It is evident that the difference in CD annular size and its match with the C18 of HMPAA control the diversity of the interactions of alpha-CD, beta-CD, gamma-CD, alpha-CDPAA, and beta-CDPAA with HMPAA.

  • The isomers of cinnamoyl alpha-CDs (2-CiO-alpha-CD and 3-CiO-alpha-CD) organize by themselves to give different types of supramolecular complexes in aqueous solutions.
  • 2-CiO-alpha-CD was found to form a double-threaded dimer, which was characterized by single crystal X-ray analysis.
  • The molecular sizes of supramolecular complexes consisting of CiO-alpha-CDs were estimated by pulsed field gradient spin-echo NMR, which gives the diffusion coefficient (D).
  • D of 2-CiO-alpha-CD was found to be 2.3 x 10(-10) m(2)/s at concentrations over 10 mM and D was saturated.
  • It should be noted that the hydrodynamic radius derived from D of 2-CiO-alpha-CD was found to be 9.6 A, which closely matched the result from the single crystal X-ray analysis.
  • D of 3-CiO-alpha-CD, however, was smaller than that of 2-CiO-alpha-CD at concentrations over 32 mM, indicating that 3-CiO-alpha-CD formed a supramolecular oligomer.
  • Two-dimensional (2D)-ROESY spectra of the mixture of 2-CiO-alpha-CD and 3-CiO-alpha-CD did not show a correlation between the same species; rather, correlation peaks between 2-CiO-alpha-CD and 3-CiO-alpha-CD were observed.
  • D's of a mixture of 2-CiO-alpha-CD and 3-CiO-alpha-CD were found to be larger than those of 2-CiO-alpha-CD and 3-CiO-alpha-CD, respectively, indicating that the mixture of 2-CiO-alpha-CD and 3-CiO-alpha-CD formed an alternative supramolecular oligomer and not a self- or random- supramolecular complex.

  • The molecular status of a freeze-dried sample or a ground mixture of p-dimethylaminobenzonitrile (DMABN) with alpha-, beta-, or gamma-cyclodextrins (CDs) was examined using solid-state fluorescence measurements.
  • Emission peaks of freeze-dried samples were observed at 450, 380, and 393 nm in alpha-CD/DMABN, beta-CD/DMABN, and gamma-CD/DMABN systems, respectively.
  • It was speculated that DMABN molecules existed as a twisted form in the cavity of alpha-CD, and as a plane structure in that of beta-CD or gamma-CD.
  • On the other hand, fluorescence emission peaks of ground mixtures of DMABN with alpha-, beta-, or gamma-CD were observed at around 450 nm.
  • When DMABN was ground together with microcrystalline cellulose, which cannot form an inclusion complex, only TICT emission was detected.
  • When the ground mixtures were crystallized under humid conditions, fluorescence emission peaks were observed at 450 nm in alpha-CD and of around 400 nm in beta- and gamma-CD systems.

  • AIM: To evaluate roles of syndecan-1, bcl6 and p53 in diagnosis and prognostication of immunoproliferative small intestinal disease (IPSID) and to study profiles of kappa (kappa) and lambda (lambda) light chains and IgA heavy chain.
  • METHODS: The study consisted of 11 cases of IPSID and similar number of controls which included 11 of normal intestinal mucosa and 11 of high grade B cell lymphoma of ileum.
  • The parameters analyzed included clinical profiles, biochemical and other laboratory investigations, radiologic and histological findings including immunohistochemistry.
  • RESULTS: All IPSID cases had demonstrable serum IgA heavy chain and heavy mucosal plasma cell infiltration.
  • According to Galian's histological staging, there were 4 patients with stage A and 7 with stage B. kappa and lambda light chains were over-expressed in 7 patients; 1 stage A patient had H pylori-positive active gastritis and eradication of H pylori led to disease remission.
  • Syndecan-1, kappa and lambda light chains and IgA heavy chain showed inverse relationship with bcl6 and p53.
  • CHOP regime was added in 5 patients who developed frank lymphoma.
  • Three died of the disease due to extensive organ infiltration.
  • CONCLUSION: Certain immunomarkers like syndecan-1, kappa and lambda light chains and IgA heavy chain could be of much help in identifying early stage IPSID.
  • Stage B IPSID showed higher expression for bcl6 and p53 than stage A IPSID. bcl6 and p53 expressions correlated with a more advanced disease stage and aggressive tumour behavior.

  • However, the cinnamoyl group at the C(3)- and C(6)-positions of alpha-CD did not affect the polymerization ability.
  • The polymerization activity could be switched by the photoisomerization of the cinnamoyl group attached to the rim of alpha-CD.
  • Specific monomer recognition and polymerization in the active site of the alpha-CD cavity was changed by the photoisomerization.

  • [Title] Coeliac disease.
  • Coeliac disease is an autoimmune disorder of the small bowel that occurs in genetically predisposed people of all ages from middle infancy.
  • Coeliac disease is caused by a reaction to gliadin, a gluten protein found in wheat.
  • Upon exposure to gliadin, the enzyme tissue transglutaminase modifies the protein and the immune system cross reacts with the bowel tissue, causing an inflammatory reaction that leads to flattening of the lining of the small intestine, which interferes with the absorption of nutrient's.
  • He had loose mucoid stool, abdominal distension, bloating and history of loss of weight for two years.
  • Along with the routine examinations foecal fat estimation, MT, USG of whole abdomen, Barium follow through, endoscopic biopsy and tissue transglutaminage IgA autoantibody was done.
  • Histopathological report was in favour of immunoproliferative small intestinal disease.
  • Tissue transglutaminage IgA autoantibody was in higher level though done in a gluten free state.
  • Symptoms of diarrhoea, abdominal distention and bloatedness gradually decreased.
  • For patients presenting with alteration of bowel habit, abdominal distension, bloating and history of weight loss for long time, the importance of considering coeliac diseases as a differential diagnosis cannot be overemphasized.

  • A new category of mechanized nanoparticles, consisting of a hollow mesoporous silica spherical framework controlled by a supramolecular system containing the alpha-cyclodextrin (alpha-CD) ring on a stalk that is tethered to the pore openings on the nanosphere, is synthesized and tested.
  • Construction of the nanovalve relies on the hydrogen-bonding interaction between alpha-CD and the stalk.
  • When the alpha-CD ring is complexed with the stalk at neutral pH, the bulky cyclic component is located near the pore openings, thereby blocking departure of cargo molecules that were loaded in the nanopores and hollow interior of the particle.
  • Protonation of the nitrogen atoms at lower pH causes the binding affinity to decrease, releasing the alpha-CD and allowing the cargo molecules to escape.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • With the use of iTRAQ labeling and mass spectrometry on an LTQ-Orbitrap with HCD capability, we assessed relative changes in protein phosphorylation in the mitochondria upon physiological perturbation.
  • As a reference reaction, we monitored the well-characterized regulation of pyruvate dehydrogenase (PDH) activity via phosphorylation/dephosphorylation by pyruvate dehydrogenase kinase/pyruvate dehydrogenase phosphatase in response to dichloroacetate, de-energization and Ca2+.
  • Dephosphorylation at Ser292 (i.e., the inhibitory site) with DCA correlated with an activation of PDH activity as previously reported, consistent with our de-energization data.
  • (1) BCKDH-E1alpha subunit increased phosphorylation at Ser337 with DCA and de-energization;.
  • (3) ATP synthase F1 complex alpha subunit and (4) mitofilin dephosphorylated at Ser65 and Ser264 upon de-energization.
  • This screening validated the iTRAQ/HCD technology as a method for functional quantitation of mitochondrial protein phosphorylation as well as providing insight into the regulation of mitochondria via phosphorylation.

  • Abnormal increases in the levels of malondialdehyde, protein carbonyl and 8-hydroxy-2-deoxyguanosine, as well as depressed antioxidants status, were observed in hepatic tissue of HCD fed rats.
  • HCD induced abnormal elevation in the activities of hepatic lactate dehydrogenase, aminotransferases and alkaline phosphatase (ALP) and was accompanied by increased hepatic cholesterol level and altered fatty changes in the histology of liver.

  • In the present study, we demonstrated that the expression of Redd1 in response to hypoxia (1% O(2)), hypoxia-mimetic agent, cobalt chloride (CoCl(2)) and high cell density (HCD) requires coactivation of HIF-1alpha and Sp1.
  • CoCl(2) and HCD induced the activation of HIF-1alpha and Sp1 in HeLa cells, and siRNAs targeting HIF-1alpha and Sp1 abrogated Redd1 expression.
  • Inhibition of phosphatidylinositol 3-kinase (PI3K) by LY294002 and by a dominant-negative PI3K mutant reduced the expression of Redd1 and activation of HIF-1alpha and Sp1 by CoCl(2) and HCD.
  • Also, suppression of Akt activation blocked the expression of Redd1 and the activation of HIF-1alpha and Sp1 by CoCl(2) and HCD.
  • These results demonstrate that hypoxic condition-and HCD-induced expression of Redd1 is mediated by coactivation of Sp1 and HIF-1alpha downstream of the PI3K/Akt signaling pathway.

  • To select for optimal carrier for in vivo study, the release kinetic of CS embedded in five types of hydrogel was studied using fluorescence technique and their biocompatibilities in vivo were investigated by injecting the CS-hydrogel into rabbit knees. alpha-CD-EG 4400 hydrogel was chosen as the carrier based on progressively released CS from the hydrogel, with 80% released by in one week while the remaining 20% was retained for 30 days.
  • CS (100 mg/ml) in 0.5 ml alpha-CD-EG 4400 hydrogel was then injected into the knee joint.
  • Our results suggest that intra-articular delivery of CS by alpha-CD-EG 4400 improved the biomechanical and histological properties of the repaired cartilage.

  • The general complexation scheme as well as the dynamic features of the supramolecular structures resulting from the interaction of the laser dye 2,5-diphenyl-1,3,4-oxadiazole (PPD) with the naturally occurring alpha-, beta-, and gamma-cyclodextrins in water are studied by means of fluorescence spectroscopy, both steady-state (SS) and time-resolved (TR).
  • PPD interacts weakly, from a thermodynamic point of view, with alpha-cyclodextrin (alpha-CD), forming 1:1 complexes with an association constant of K(11) = 85 +/- 4 M(-1).
  • However, the local motion of the substrate (PPD) with respect to the ligand (CD) in the complexed form is hindered; namely, dynamically, they are strongly coupled and only a global tumbling motion, = 370 +/- 30 ps, of the whole adduct is observed.
  • The next homologue beta-CD also forms 1:1 entities with PPD, but although the binding strength of reactants (K(11) = 682 +/- 60 M(-1)) is almost an order of magnitude greater than the former case with the alpha-CD, these are dynamically weakly coupled.

  • [Title] MALT lymphoma : recent advances in aetiology and molecular genetics.
  • Mucosa-associated lymphoid tissue (MALT) lymphoma is a common low grade B-cell lymphoma arising from a background of chronic inflammatory disease at a number of mucosal sites.
  • Those originating in the stomach are causatively linked to Helicobacter pylori infection and eradication of the bacterium with antibiotics leads to long-term complete regression of the lymphoma in aproximately 70% of cases.
  • Now, there is further evidence of linking Campylobacter jejuni, Borrelia burgdorferi and Chlamydia psittaci infection with immunoproliferative small intestine disease, MALT lymphoma of the skin and ocular adnexa respectively. t(11;18)/API2-MALT1, t(1;14)/IGH-BCL10, t(14;18)/IGH-MALT1 and t(3;14)/IGH-FOXP1 occur at considerably variable incidences in MALT lymphomas of different sites.
  • The first three chromosome translocations are specifically associated with the MALT lymphoma entity and the oncogenic products of these translocations have been shown to target a common molecular pathway, i.e. the nuclear factor-kappaB pathway.
  • Here, I review the recent advances in our understanding of the association of microbial pathogens with MALT lymphoma of various sites and the molecular genetics underlying the lymphoma development.

  • [Title] Rheological properties of a telechelic associative polymer in the presence of alpha- and methylated beta-cyclodextrins.
  • The viscosity of hydrophobic ethoxylated urethane (HEUR) solution decreased in the presence of alpha-CD or m-beta-CD; however their interactions were quite different.
  • When the alpha-CD/hydrophobe molar ratio exceeded 5.0, the viscosity was close to that of a PEO solution of similar molecular weight.
  • Oscillatory shear indicated that the mechanically active chains in HEUR solution decreased with the addition of alpha-CD.
  • This agreed with the hypothesis that alpha-CD formed an inclusion complex with the hydrophobic moiety of the HEUR polymer, thereby destroying the transient hydrophobic associative network.
  • The viscosity/temperature relationship of the alpha-CD/HEUR system (for HEUR with 70% of the PEO chains capped at both ends) did not obey the Arrhenius relationship for alpha-CD/hydrophobe molar ratio in the range 0.8-5.0.
  • The low shear viscosity increased with increasing temperature at molar ratio of 1.0, and this was attributed to the competitive complexation of the alpha-CD/hydrophobe and the alpha-CD/PEO chain.
  • Increasing temperature favored alpha-CD/PEO complexation.
  • Comparison between the behavior of alpha-CD/HEUR and m-beta-CD/HEUR resulting from the different binding characteristics was discussed.

  • OBJECTIVES: Immunoproliferative small intestinal disease (IPSID) represents a spectrum of clinicopathological entities including alpha-chain disease and other types of lymphoplasmacytic proliferations of the lamina propria of the small intestine, presenting with severe malabsorption.
  • IPSID has been described mainly in the Mediterranean, Middle East, and African countries.
  • METHODS: Current immunological and immunohistochemical methods for the detection of alpha heavy chains and the presence of clonality have been used to study 13 cases of IPSID diagnosed in Greece, two of whom were Albanian residents.
  • RESULTS: The patients were categorized in three subgroups of IPSID: alpha-chain disease (n=8), non-alpha chain disease with other monoclonal immunoglobulins (n=3), and polyclonal 'non-malignant' IPSID (n=2).
  • In several patients the disease had unusual features, and this in some cases delayed the diagnosis.
  • Patients with stage C disease had a short survival, whereas two patients with stage A alpha-chain disease responded to treatment with cyclophosphamide, vincristine and prednisolone, and cyclophosphamide, doxorubicine, vincristine and prednisolone, respectively, have a disease-free long survival of 35 and 12 years, and appear to be cured.

  • [Title] Inclusion effect of alpha-cyclodextrin on chemical degradation of malathion water.
  • Alpha-cyclodextrin (alpha-CD), one of the cyclic oligosaccharides different from beta-cyclodextrin (beta-CD) in glucose units, solubility, and size of cavity, is capable of producing an environmental effect different from those of the latter CD and its derivatives.
  • This work evaluated the effect of alpha-CD on chemical degradation of malathion in water in an attempt to further study the effects of different CDs on hydrolysis of malathion and assess the potential applications of alpha-CD in remediation of malathion contamination.
  • The results showed that alpha-CD had a remarkable facilitative effect on the hydrolysis of malathion in both buffer solutions and natural surface waters.
  • The facilitative effects of alpha-CD were an obverse function of pH value and inverse function of temperature.
  • The rate constant of malathion hydrolysis increased with increasing the concentration of alpha-CD in both types of waters.
  • Urea, a compound widely used in agriculture, decreased the facilitative effect of alpha-CD at 25 degrees C and pH 9.0.
  • The formation of inclusion complexes between alpha-CD and malathion was evidenced by nuclear magnetic resonance studies.

  • The influence of the organic solvent on the acid and basic hydrolysis of N-methyl-N-nitroso-p-toluenesulfonamide (MNTS) in the presence of alpha- and beta-cyclodextrins has been studied.
  • The basic and acid hydrolysis of MNTS in the presence of alpha-CD showed a different behavior; thus, the reaction gave both 1 : 1 and 2 : 1 alpha-CD-MNTS complexes, of which only the former was reactive.
  • This result was due to the smaller cavity size of alpha-CD and the consequent decreased penetration of MNTS into the cavity in comparison to beta-CD.
  • The acid hydrolysis of MNTS in the presence of alpha-CD also revealed decreased penetration of MNTS into the cyclodextrin cavity, as evidenced by the bound substrate undergoing acid hydrolysis.
  • In addition, the acid hydrolysis of MNTS in the presence of acetonitrile containing alpha-CD gave 1 : 1 alpha-CD-acetonitrile inclusion complexes, which is consistent with a both a reduced cavity size and previously reported data.

  • [Title] A redox-switchable alpha-cyclodextrin-based [2]rotaxane.
  • A bistable [2]rotaxane comprising an alpha-cyclodextrin (alpha-CD) ring and a dumbbell component containing a redox-active tetrathiafulvalene (TTF) ring system within its rod section has been synthesized using the Cu(I)-catalyzed azide-alkyne cycloaddition, and the redox-driven movements of the alpha-CD ring between the TTF and newly formed triazole ring systems have been elucidated.
  • Microcalorimetric titrations on model complexes suggested that the alpha-CD ring prefers to reside on the TTF rather than on the triazole ring system by at least an order of magnitude.
  • The fact that this situation does pertain in the bistable [2]rotaxane has not only been established quantitatively by electrochemical experiments and backed up by spectroscopic and chiroptical measurements but also been confirmed semiquantitatively by the recording of numerous cyclic voltammograms which point, along with the use of redox-active chemical reagents, to a mechanism of switching that involves the oxidation of the neutral TTF ring system to either its radical cationic (TTF*+) or dicationic (TTF2+) counterparts, whereupon the alpha-CD ring, moves along the dumbbell to encircle the triazole ring system.

  • [Title] Sonoenteroclysis: a new technique for the diagnosis of small bowel diseases.
  • BACKGROUND: Radiologic evaluation of small bowel is usually done by barium examination, which involves considerable radiation exposure.
  • A new sonographic method, sonoenteroclysis, is a promising technique for diagnosing small intestinal disorders.
  • METHODS: Forty-five consecutive patients with suspected small bowel disorder were studied.
  • All patients underwent abdominal ultrasound before and after infusion of an isotonic nonabsorbable electrolyte solution containing polyethylene glycol through a nasojejunal tube (modified Billbao Dotter tube), and images at various levels were obtained.
  • Small bowel wall thickness, luminal narrowing, intestinal dilatation, peristalsis, and extraintestinal complications were noted.
  • RESULTS: Satisfactory distention of the intestinal lumen was obtained with sequential visualization of jejunoileal loops in 34.4 +/- 18.4 min.
  • Of 45 patients, 10 showed normal small bowel on sonoenteroclysis and barium enteroclysis.
  • The remaining 35 patients showed abnormalities in the form of strictures, matted bowel loops, dilated loops, thickened folds, deformed ileocecal junction, mass lesions, etc., on sonoenteroclysis and barium enteroclysis.
  • These were diagnosed subsequently as cases of tuberculosis (n = 23), celiac disease (n = 6), adenocarcinoma (n = 2), leiomyoma (n = 2), Immunoproliferative small intestinal disease (n = 1), and segmental enteritis (n = 1).
  • CONCLUSIONS: The diagnostic accuracy of sonoenteroclysis for detecting small bowel lesions is comparable to that of barium enteroclysis.
  • This new, widely available, inexpensive, and undemanding technique can be used as an initial investigation in the evaluation of patients with small bowel disorders.

  • EPO receptor (EPOR) messenger RNA (mRNA) was detectable in both B16F10 tumors and mammary tumors from MMTV-PyMT mice but was 0.12 +/- 0.02% and 1.3 +/- 0.91% of the EPOR mRNA level in murine erythroid HCD-57 cells, respectively.
  • B16F10 tumor growth rates in mice treated for 3 weeks with 30 microg/kg per week of darbepoetin alpha, 0.41 inverse days (range, 0.05-0.69 inverse days; n = 16), were similar to tumor growth rates observed in mice treated with PBS, 0.42 inverse days (range, 0.10-0.69 inverse days; n = 17).
  • In contrast, darbepoetin alpha raised hematocrit levels to 0.593 (maximum, 0.729) compared with 0.448 (maximum, 0.532) in PBS-treated mice (P = .0004).
  • In MMTV-PyMT mice, the weights of tumor-bearing mammary glands in mice treated for 6 weeks with 30 microg/kg per week of darbepoetin alpha, 3.37 g (range, 1.94-5.81 g; n = 27), did not significantly differ from the weights in PBS-treated mice, 3.76 g (range, 2.30-6.33 g; n = 26).
  • In contrast, darbepoetin alpha raised hematocrit levels to 0.441 (maximum, 0.606) compared with 0.405 (maximum, 0.492) in PBS-treated mice (P = .05).

  • The thermodynamics and kinetics of formation of host-guest complexes between a series of bolaform surfactants of type C n Me 6 (2+)2Br (-) ( n = 8, 10, and 12) and alpha-cyclodextrin and beta-cyclodextrin were studied with the aid of isothermal titration calorimetry (ITC) at 298.15 and 308.20 K.
  • The difference in magnitude and sign between the parameters of the alpha-CD and beta-CD complexes is discussed based on the curvature of the cavity of the CD.
  • We suggest that the water molecules inside the alpha-CD cavity are not able to maintain their hydrogen bond network.
  • The kinetics for alpha-CD is slow, associated with high activation energies for both association and dissociation of the complex.
  • The rates increased with a decrease in the number of methylene groups in the hydrocarbon chain.

  • [Title] Inclusion complexes of alpha- and gamma-cyclodextrins and the herbicide norflurazon: I. Preparation and characterisation. II. Enhanced solubilisation and removal from soils.
  • The interaction of norflurazon with alpha- and gamma-cyclodextrins (CDs) yielded the formation of inclusion complexes at a 1:1 stoichiometric ratio in solution and in the solid state.
  • Apparent stability constants of 50.7+/-1.6 and 37+/-1.7 M(-1) and an increase in herbicide solubility by up to five and fourfold for alpha- and gamma-CD, respectively, were determined from the phase solubility diagrams at 25 degrees C in water.
  • A high increase in the norflurazon dissolution rate was obtained with all the solid complexes with gamma-CD, but when alpha-CD was used, only the solid system obtained after the vacuum evaporation process showed a higher dissolution rate.
  • This finding is a first step in the development of new, environmentally sound formulations of norflurazon (NFL), due to the capacity for increasing its dissolution rate and hydrosolubility, and thus diminishing the use of organic solvents.
  • On the other hand, the effect of alpha- and gamma-cyclodextrin on the solubility of norflurazon in solution was also considered as a way of modifying its behaviour in the soil environment.
  • Desorption studies of NFL from soils in the presence of alpha- and gamma-cyclodextrin were carried out using a batch equilibration method.
  • The results obtained showed that alpha- and gamma-cyclodextrin greatly increased the removal of norflurazon previously adsorbed, proving the potential use of these CDs for in situ remediation of pesticide-contaminated soils.

  • In this paper, the color of fresh peach juice was evaluated in the presence of two types of natural (alpha-CD and beta-CD) and a modified (maltosyl-beta-CD) CD, and the effectiveness of these compounds as browning inhibitors was determined using the color space CIELAB system.
  • The results show that the highest affinity constant was presented by alpha-CD (Kc = 18.31 mM-1) followed by maltosyl-beta-CD (Kc = 11.17 mM-1), whereas beta-CD was incapable of inhibiting peach juice enzymatic browning.

  • Here, we investigated this possibility by comparison of the effects of cholesterol depletion by MbetaCD and by metabolic inhibition (compactin), and of treatment with alpha-CD, which does not bind cholesterol.
  • Moreover, alpha-CD also inhibited the diffusion of raft and non-raft mutants, despite its lack of effect on cholesterol content.

  • [Title] Heavy chain diseases.
  • Heavy chain diseases (HCDs) are rare B-cell lymphoplasma-cell proliferative disorders characterized by production of truncated monoclonal immunoglobulin heavy chains without associated light chains.
  • HCDs involving the three main immunoglobulin classes have been described; alpha-HCD is the most common and has the most uniform presentation, gamma- and mu-HCDs have variable clinical presentations and histopathologic features.
  • HCDs can be thought of as variant types of non-Hodgkin lymphoma: alpha-HCD presents as an extranodal marginal-zone lymphoma of mucosa-associated lymph-node tissue, gamma-HCD as lymphoplasmacytoid non-Hodgkin lymphoma, and mu-HCD as small lymphocytic non-Hodgkin lymphoma or chronic lymphocytic leukemia.
  • Diagnosis of HCD requires documentation of a deleted immunoglobulin heavy chain without a bound light chain in the serum or urine.
  • Prognosis is variable, and no standardized effective treatment programs are available except for alpha-HCD, which in its early stage may respond to antibiotics.

  • [Title] Kinetic aspects of alkaline phosphatase refolding in the presence of alpha-cyclodextrin.
  • To get a better understanding of the molecular aspects of protein folding, the refolding kinetic behavior of guanidine hydrochloride-denatured alkaline phosphatase (ALP) was studied in the presence of alpha-cyclodextrin (alpha-CD) through two different approaches: the dilution additive and the artificial chaperone-assisted methods.
  • It was found that alpha-CD enhanced the recovered activity more than 50% via both approaches while decreased the refolding rate, perhaps due to engaging the hydrophobic patches of the protein in a rigid conformation.

  • OBJECTIVE: Most strategies against intimal hyperplasia developed in several preclinical models failed in terms of clinical application, often due to a discrepancy between animal and human disease.
  • METHODS: Pigs were fed with standard (SD, n=7) or high-cholesterol diet (HCD, n=7) for 120 days.
  • HCD significantly increased the degree of stenosis (48+/-3% vs. 13+/-4%, p=0.001), with induction of cell proliferation, matrix deposition, TGF-beta1/TGFbetaRII and MMP2 expression and reduction of collagen.
  • The reduced expression of the protective gene heme oxygenase-1 and inducible-nitric oxide synthase in HCD was associated to a systemic inflammation with a significant increase in circulating leukocytes, serum IFN-gamma and TNF-alpha and a local inflammatory response with an increase of CD3-positive cell infiltrates.
  • New therapeutical strategies to prevent restenosis can be tested in this preclinical hypercholesterolemic model resembling human disease.

  • [Title] Lipid lowering effect of antioxidant alpha-lipoic Acid in experimental atherosclerosis.
  • In the present study, a protective activity of alpha-lipoic acid; a metabolic antioxidant in hypercholesterolemic-induced animals was investigated.
  • Eighteen adult male New Zealand White (NZW) rabbit were segregated into three groups labelled as group N, HCD and ALA (n = 6).
  • Group N (normal control) was fed with normal chow, the rest (HCD and ALA) were fed with 100 g/head/day of 1% cholesterol rich diet to induce hypercholesterolemia.
  • Four point two mg/body weight of alpha lipoic acid was concomintantly supplemented to the ALA group.
  • The plasma total cholesterol (TC) and low density lipoprotein (LDL) levels were found to be significantly low in ALA group compared to that of the HCD group (p<0.05).
  • Similarly, low level of MDA (p<0.05) in ALA group was observed compared to that of the HCD group showing a significant reduction of lipid peroxidation activity.
  • Histomorphometric intimal lesion analysis of the aorta showing less of atheromatous plaque formation in alpha lipoic acid supplemented group (p<0.05) compared to HCD group.
  • These findings suggested that alpha lipoic acid posses a dual lipid lowering and anti-atherosclerotic properties indicated with low plasma TC and LDL levels and reduction of athero-lesion formation in hypercholesterolemic-induced rabbits.

  • Calcium alginate beads covalently linked with alpha-cyclodextrin (alpha-CD-alginate beads) were prepared and examined for their ability to serve as a supporting matrix for bacterial degradation of nonylphenol, an endocrine disruptor.
  • Column chromatographic experiment using alpha-CD-alginate beads with diameter of 657+/-82 microm and with degree of CD substitution of 0.16 showed a strong affinity for nonylphenol adsorption.
  • Although addition of alpha-CD (2.7-27 mM) to the culture broth of Sphingomonas cloacae retarded nonylphenol degradation, the immobilized bacteria on the CD-alginate beads were effective for the degradation.
  • Batch degradation tests using the immobilized bacteria on alpha-CD-alginate-beads showed 46% nonylphenol recovery after 10-day incubation at 25+/-2 degrees C, and the recovery reached to about 17% when wide and shallow incubation tubes were used to facilitate uptake of the viscous liquid of nonylphenol on the surface of the medium.

  • [Title] Study on preparation and formation mechanism of n-alkanol/water emulsion using alpha-cyclodextrin.
  • In this study, we examined the preparation and formation mechanism of n-alkanol/water emulsions using alpha-cyclodextrin (alpha-CD) as an emulsifier.
  • From phase diagrams of n-alkanol/alpha-CD/water systems, the emulsion phase extended as the chain length of n-alkanols and the amount of alpha-CD added increased.
  • Furthermore, the emulsion was not formed in the region where the n-alkanol/alpha-CD complex didn't precipitate; however, the emulsion was formed in the region where the complex precipitated.
  • Our experiments clearly showed that the stable emulsions are formed because the precipitated complexes form a dense film at the oil-water interface and prevent aggregation among dispersed phases.
  • Thus, we concluded that the n-alkanol/water emulsions using alpha-cyclodextrin were a kind of the Pickering emulsion.

  • The stoichiometric ratio in the BP(OH)2/(alpha-CD) complex is dominated by 1:2, whereas in all other CDs and in HSA this ratio is 1:1.
  • The structure of the BP(OH)2:(alpha-CD)2 complex, calculated using ab initio methods, indicates that the inclusion of the BP(OH)2 molecule is axial and centered between the two cavities of alpha-CD with van der Waals and electrostatic interactions dominating the binding.
  • This change is reflected in the form of a decrease in the intensity of the absorption peaks of the BP(OH)2/water complex in the region 400-450 nm and a red shift in the fluorescence peak as the cavity size decreases and its hydrophobicity increases.

  • [Title] The combined effects of two anti-aggregatory agents, alpha-cyclodextrin and Ca2+, on the refolding process of denatured alpha-amylase.
  • It is now a well-known fact that alpha-CD (alpha-cyclodextrin) and Ca(2+) are two important folding agents in the re-activation and refolding processes of many denatured enzyme solutions.
  • Bacillus sp. alpha-amylase was extensively denatured in a 6 M guanidinium chloride solution overnight.
  • Under suitable renaturation conditions, 20-30% more activity was recovered in the presence of various concentrations of alpha-CD (0-100 mM).
  • Regardless of these results, both alpha-CD and Ca(2+) at 100 mM concentrations were separately capable of preventing the extent of aggregate formation by 86 and 77% respectively.
  • These observations clearly indicate that the effects of alpha-CD and/or Ca(2+) on the process of aggregation and refolding (activity recovery) are not synchronized: both agents mostly act as anti-aggregatory agents instead of acting as refolding agents.

  • [Title] Models of pesticides inside cavities of molecular dimensions. A role of the guest inclusion in the dechlorination process.
  • The reduction mechanism of the pesticide vinclozoline (3-(3,5-dichlorophenyl)-5-methyl-5-vinyl-1,3-oxazolidine-2,4-dione) was studied in nonaqueous solvents in the confined environment of a cyclodextrin (CD) cavity.
  • The effect of the cavity dimensions on the mechanism of the redox process was evaluated using glucose as a reference and using three cyclodextrin molecules of different cavity sizes, namely, alphaCD, betaCD, and gammaCD.
  • In the absence of CD the main reduction product of vinclozoline in the first reduction step is dichloroaniline.
  • An addition of glucose leads to a quantitative change of mechanism with 10 products in total.
  • Addition of CD, however, leads exclusively to dechlorination of the phenyl ring.
  • The degree of dechlorination depends strongly on the choice of cyclodextrin molecule.
  • The importance of the complex formation equilibria in the change of the mechanism is supported by a series of semiempirical AM1 quantum-mechanical calculations.
  • Very good correlation (correlation coefficient 0.995) was obtained between the complex stabilization energy of the inclusion complex and the degree of pesticide dechlorination.
  • Additionally, we were able to show that the complexes are stabilized by the formation of intermolecular hydrogen bonds between the host and guest species.
  • CD molecules do not simply act as proton donors in a nonaqueous environment, but also protect parts of the molecule included within the cavity and steer the degradation process toward fewer products.

  • [Title] Spectrofluorimetric determination of benzoimidazolic pesticides: effect of p-sulfonatocalix[6]arene and cyclodextrins.
  • The effect of the addition of a macrocyclic host (H) such as p-sulfonatocalix[6]arene (C6S), native and modified cyclodextrins (CDs), on the fluorescence of benzoimidazolic fungicides (P), like Benomyl (BY) and Carbendazim (CZ), has been studied.
  • The fluorescence of BY in water at pH 1.000 and 25.0 degrees C was increased in the presence of C6S, alphaCD and hydroxypropyl-beta-CD (HPCD).
  • The association constants determined by fluorescence enhancement showed weak interactions (K(A) approximately 10(1) to 10(2) M(-1)) between the fungicide with both CDs, whereas they were stronger with C6S (K(A) approximately 10(5) M(-1)).
  • Molecular recognition of BY for C6S was mainly attributed to electrostatic interactions, and for CDs to the hydrophobic effect and hydrogen bond formation.
  • On the other hand, the fluorescent behaviour of CZ in the presence of C6S at pH 6.994 was interpreted as the formation of two complexes with 1:1 (P:H) and 1:2 (P:H(2)) stoichiometry, the latter being less fluorescent than the free analyte.
  • Relative fluorescence quantum yield ratios between the complexed and free BY (phi(P:H)/phi(P)) were 2.00+/-0.05, 1.40+/-0.03 and 2.8+/-0.4 for C6S, alphaCD and HPCD, respectively.
  • The analytical parameters improved in the presence of C6S and CDs.
  • The best limit of detection (L(D), ng mL(-1)) was 17.4+/-0.8 with HPCD.
  • The proposed method with C6S and HPCD was successfully applied to fortified samples of tap water and orange flesh extract with good recoveries (91-106%) and R.S.D. (< or = 2%) by triplicate analysis.
  • The method is rapid, direct and simple and needs no previous degradation or derivatization reaction.

  • The animals were fed standard laboratory diet (CD) or control diet containing 5% fat and 2% cholesterol (HCD) for two weeks.
  • Although the basal cholesterolemia in PHHC was similar to controls (1.80 +/- 0.48 and 1.52 +/- 0.39 mmol/l, respectively), it rose in rats fed on HCD to 9.81 +/- 1.65 mmol/l in PHHC rats and only to 2.19 +/- 0.41 mmol/l in controls.
  • In controls on HCD, cyp7A1 gene expression increased almost 4-fold immediately on the first day and achieved up to approximately 20-multiple basal expression in the end of the feeding period.
  • Compared to the controls, after switching to HCD the cyp7A1 gene expression in PHHC rats did not change dramatically.

  • [2]Rotaxane and [3]rotaxane are composed of alpha-cyclodextrin (alpha-CD) rotors, a decamethylene chain, and a stilbene unit as axes and an altro-alpha-CD stopper containing one altropyranose unit and five glucopyranose units.
  • The alpha-CD rotor of [2]rotaxane includes the decamethylene chain in DMSO-d(6) and moves to include the stilbene group in D(2)O.
  • It should be noted that the altro-alpha-CD stopper group reorients to include the decamethylene chain in D(2)O.
  • These studies showed that an altropyranose unit of the altro-alpha-CD stopper tumbles to form a self-inclusion complex in aqueous solution.
  • The altro-alpha-CD stopper of [2]rotaxane reels an axis molecule into its cavity and then pushes the alpha-CD rotor onto the stilbene group, resulting in conversion to pseudo[2]rotaxane in D(2)O.
  • In contrast, the rotors of [3]rotaxane did not show shuttling because there was insufficient space not only for the rotors to shuttle but also for the altro-alpha-CD stopper to include an axis after tumbling.
  • The decamethylene chain and the stilbene group are already included in the rotors of [3]rotaxane.
  • The tumbling of the altro-alpha-CD stopper was found to play a critical role in controlling the shuttling of rotors.
