  • To study the origin and the effects of steric strain on the chromophore conformation in rhodopsin, we have performed quantum-mechanical calculations on the wild-type retinal chromophore and four retinal derivatives, 13-demethyl-, 10-methyl-13-demethyl-, 10-methyl-, and 9-demethylretinal.
  • As a result, the polyene chain, from N16 to C13, is twisted in a clockwise manner against the remaining part of the chromophore, leading to a C11=C12 bond with the observed negative dihedral angle.
  • Shifts of the absorption maxima are reproduced correctly, in particular, the red shift of the 10-methyl and the strong blue shift of the 9-demethyl analogue relative to the wild type.
  • Calculated positive rotatory strengths of the alpha-CD bands are in agreement with the calculated absolute conformation of the mutant chromophores.

  • [Title] [Algorithm for diagnosis of small intestinal diseases].
  • AIM: To review diagnostic approaches in chronic diseases of the small intestine.
  • MATERIAL AND METHODS: A total of 1096 patients with chronic diseases of the small intestine were admitted to the clinic of the Central Research Institute of Gastroenterological Diseases in 1987-2006.
  • RESULTS: Most of the patients (90.5%) had celiac disease, hypolactasia and other types of disaccharidase deficiency, yersiniosis ileitis, Krohn's disease, postresection syndrome of a short small intestine, mesenterial ischemia and endocrine enteropathy.
  • Rare diseases (general variable hypogammaglobulinemia, lymphoma, Wipple's disease and diverticulosis of the small intestine) were diagnosed in 5.8% cases.
  • Primary amyloidosis of the small intestine, eosinophilic gastroenteritis, arteriomesenterial obstruction, primary intestinal pseudoobstruction, hypogammaglobulinemic spru, primary intestinal lymphangiectasia, tuberculosis, total polyposis, Peutz-Eggers and Cronkhite-Canada syndromes, collagenic sprue, erosive-ulcerative jejunoileitis, adenocarcinoma and heavy alpha-chain disease were detected in 3.7% examinees.
  • These diseases were encountered in one to 5 cases for the latest 20 years.
  • CONCLUSION: Clinical diagnosis of small intestinal diseases is based on the syndromes of chronic diarrhea, defective absorption, enteral protein loss, small intestinal obstruction and intestinal hemorrhage.
  • Differential diagnosis of the nosological entities employs x-ray, endoscopic, histological, immunological and other methods.
  • Most of the small intestinal diseases including rare can be diagnosed in any gastroentorological department.

  • [Title] Experimental and theoretical studies on the inclusion complexation of syringic acid with alpha-, beta-, gamma- and heptakis(2,6-di-O-methyl)-beta-cyclodextrin.
  • Intermolecular interactions of alpha-, beta-, gamma- and heptakis(2,6-di-O-methyl)-beta-cyclodextrin (CD) with syringic acid (Syr) in aqueous solution are investigated by fluorescence spectroscopy.
  • The association abilities of Syr with the CDs decrease in the order gamma->beta->alpha- approximately DMbeta-CD.
  • Based on the results of NMR experimental and theoretical PM3 calculations both in vacuo and in water, it is found that Syr stays near the wider rim of alpha-CD cavity.
  • Both the number of substituted groups (NSG) in a guest and the molar volume ratio of the guest to host cavity (MVR) play an important role in forming the CD supramolecular complexes of a homologous series of phenol derivatives, such as 2-methoxylphenol (2-Mop), eugenol (Eug) and Syr, i.e., an appropriate NSG or MVR in an inclusion system, such as in 2-Mop-alpha-CD, Eug-beta-CD and Syr-gamma-CD systems, can maximize the intermolecular interaction between host and guest.

  • The CD's stuck: Poly(ethylene glycol) chains anchored onto gold nanoparticles (AuNPs) are threaded by multiple alpha-cyclodextrin (alpha-CD) rings to form a supramolecular outer layer composed of pseudopolyrotaxane columns perpendicular to the nanoparticle surface.
  • Capping the polymer ends confines alpha-CD on the nanoparticle surface, cross-linking the alpha-CD rings and then removing the AuNP cores produces supramolecular nanocapsules.

  • [Title] Nonsecretory variant of immunoproliferative small intestinal disease: a case report with pathologic, immunophenotypic, and molecular findings.
  • We report a case of the nonsecretory variant of immunoproliferative small intestinal disease involving the distal small bowel and the mesenteric and retroperitoneal lymph nodes in a 19-year-old woman from Mexico.
  • This variant extranodal marginal zone B-cell lymphoma appeared similar in the different sites of involvement, with more interspersed large cells and greater plasmacytic differentiation present in intestinal specimens.
  • Characteristic lymphoepithelial lesions and follicular colonization were seen in intestinal and lymph node sections, respectively.
  • The neoplastic B cells were cytoplasmic immunoglobulin (Ig) A heavy-chain restricted and lacked surface and cytoplasmic light-chain expression by flow cytometric analysis.
  • Molecular studies showed absence of immunoglobulin heavy-chain (IgH) gene rearrangement, with a nonfunctional clonotypic rearrangement of the kappa light-chain gene.
  • This case highlights the role for kappa light-chain gene evaluation in immunoproliferative small intestinal disease, because IgH gene rearrangement analysis is often negative.

  • [Title] Supramolecular hydrogels based on inclusion complexation between poly(ethylene oxide)-b-poly (epsilon-caprolactone) diblock copolymer and alpha-cyclodextrin and their controlled release property.
  • Supramolecular hydrogels formed through inclusion complexation between high molecular weight poly(ethylene oxide) (PEO) and alpha-cyclodextrin (alpha-CD) showed the most sustained release kinetics in vitro with molecular weight of PEO of 35,000 within 5 days.
  • Compared with that of alpha-CD/PEO supramolecular hydrogels, the sustained release of alpha-CD/PEO-PCL supramolecular hydrogel was increased significantly even if with much lower molecular weight of PEO block.
  • The sustained release is also dependent on the alpha-CD content in supramolecular hydrogels.
  • Thus, the properties of supramolecular hydrogel can be fine-tuned with different polymer and at different alpha-CD content, opening a wide range of applications.

  • An alkyl altro-alpha-CD dimer was converted to the pseudo[1]rotaxane dimer through tumbling of the altropyranose unit of altro-alpha-CD in D(2)O.
  • The activation free energy (DeltaG(double dagger)(288K)) for the conformational change from an alkyl altro-alpha-CD dimer to pseudo[1]rotaxane dimer was 88.0 kJ mol(-1), which corresponds to the breakage of the hydrogen bond network for the tumbling of an altropyranose unit.

  • The nanostructures produced were spherical in shape as observed by transmission electron microscopy (TEM) and possessed radii that were much larger than that of a single stretched polymeric chain.
  • The above results suggested that the nanostructures formed in the PEO-b-PAA/alpha-CD solution at high pH were likely to be spherical vesicles.

  • [Title] Orientational isomers of alpha-cyclodextrin [2]semi-rotaxanes with asymmetric dicationic threads.
  • Two series of novel dicationic threading molecules [Quin(CH2)10R]2+ and [3,5-Lut(CH2)10R]2+, where Quin+ = quinuclidinium, 3,5-Lut+ = 3,5-lutidinium, and R+ = N(CH3)3+ and N(CH3)2CH2CH3+, form [2]semi-rotaxanes with [small alpha]-cyclodextrin (alpha-CD) in aqueous solution.
  • The quinuclidinium and 3,5-lutidinium are sufficiently bulky to prevent threading while the R+ groups allow for slow threading by alpha-CD at 25 degrees C.
  • The resulting [2]semi-rotaxanes exist in two orientational isomers owing to the asymmetry of both the alpha-CD cavity and the threading molecules.

  • The interaction of 1,4-dihydroxy-9,10-anthraquinone, (quinizarin; QZ), with alpha-, beta- and gamma-cyclodextrin (CD) hosts, has been investigated using absorption, and steady-state and time-resolved fluorescence measurements, in order to understand the effects of cavity size of CDs on the binding of QZ molecule and the changes in the photophysical properties of QZ in the microenvironment of the hosts.
  • It is proposed that the unsubstituted benzene ring of QZ is encapsulated within alpha- and beta-CD cavities whereas the dihydroxy-substituted aromatic ring is encapsulated within the gamma-CD cavity.
  • It is observed that the complexation of QZ with the metal ion is enhanced in the QZ.alpha-CD and QZ.beta-CD systems whereas it is significantly reduced in the QZ.gamma-CD system, due to shielding of the chelating groups of the dye inside the CD cavity in the latter case.

  • [Title] Capillary electrophoretic study of thiolated alpha-cyclodextrin-capped gold nanoparticles with tetraalkylammonium ions.
  • Capillary zone electrophoresis (CZE) has been employed to characterize nanometer-sized thiolated alpha-cyclodextrin-capped gold nanoparticles (alpha-CD-S-AuNPs).
  • The addition of tetrabutylammonium (Bu(4)N(+)) ions to the run buffer greatly narrows the migration peak of alpha-CD-S-AuNP.
  • The effect of various tetraalkylammonium ions on the peak width and electrophoretic mobility (mu(e)) of alpha-CD-S-AuNP was studied in detail.
  • Bu(4)N(+) ions assist in inter-linking the alpha-CD-S-AuNPs and narrowing the migration peak in CZE.
  • This observation can be explained by the fact that each Bu(4)N(+) ion can simultaneously interact with several hydrophobic cavities of the surface-attached alpha-CDs on AuNPs.
  • The TEM images show that alpha-CD-S-AuNPs with Bu(4)N(+) are linked together but in the absence of Bu(4)N(+), they are more dispersed.
  • The migration mechanism in CZE is based on the formation of inclusion complexes between Bu(4)N(+) and alpha-CD-S-AuNPs which induces changes in the charge-to-size ratio of alpha-CD-S-AuNPs and mu(e).
  • An inverse linear relationship (r(2)>0.998) exists between the mu(e) and size of alpha-CD-S-AuNPs in the core range 1.4-4.1 nm.
  • A few nanoliters of each of the alpha-CD-S-AuNP samples were injected hydrodynamically at 0.5 psi for 5s.
  • Our work confirms that CZE is an efficient tool for characterizing the sizes of alpha-CD-S-AuNPs using Bu(4)N(+) ions.

  • In both techniques, it was found that CTAB is a better additive (in dilution mode) or a capturing agent (in artificial chaperone method).
  • In dilution, using CTAB or alpha-cyclodextrin (alpha-CD) as two different additives, the aggregation was inhibited by almost 55%.
  • However, the extent of inhibition raised to almost 82% in artificial chaperone assisted mode using CTAB as the capturing and alpha-CD as the stripping agents.

  • [Title] Effects of addition of alpha-cyclodextrin on the sensory quality, volatile compounds, and color parameters of fresh pear juice.
  • Even though the addition of alpha-CD had a significant effect on both the concentration of individual volatile compounds and their grouping, only the highest concentration, 90 mM, prevented the oxidation of the volatile precursors present in freshly squeezed juice.
  • The addition of alpha-CD at 90 mM resulted in pear juices with the best color but with low aromatic intensity and low sensory quality.
  • On the other hand, the addition of alpha-CD at 15 mM led to a pear juice also with an acceptable color but at the same time with a high intensity of fruity and pear-like odors/aromas, making it the best appreciated juice by the panel.

  • We herein report a rare case of a massive upper gastrointestinal (GI) bleeding, caused by high-grade diffuse B-cell lymphoma of the duodenum, secondary to immunoproliferative small intestinal disease (IPSID) and treated with an emergency partial pancreatoduodenectomy.
  • An urgent abdominal ultrasound raised the suspicion of a large, possibly bleeding, neoplasm of the duodenum, which was finally confirmed by abdominal computed tomography.
  • Histologically, the tumor was a high-grade B-cell lymphoma of the duodenum.
  • The nearby small intestinal mucosa was suggestive of IPSID.
  • A massive upper GI hemorrhage from a high-grade B-cell non-Hodgkin lymphoma of the duodenum, which develops secondary to IPSID, is a very rare clinical demonstration of this disease.

  • [Title] Hydrogels composed of organic amphiphiles and alpha-cyclodextrin: supramolecular networks of their pseudorotaxanes in aqueous media.
  • Mixtures of N-alkyl pyridinium compounds [py-N-(CH(2))(n)OC(6)H(3)-3,5-(OMe)(2)](+)(X(-)) (1bCl: n = 10, X = Cl; 1cBr: n = 12, X = Br) and alpha-cyclodextrin (alpha-CD) form supramolecular hydrogels in aqueous media.
  • Washing the hydrogel with acetone or evaporation of water left the xerogel, and (13)C CP/MAS NMR measurements, powder X-ray diffraction (XRD), and scanning electron microscopy (SEM) revealed that the xerogel of 1bCl (or 1cBr) and alpha-CD was composed of pseudorotaxanes with high crystallinity. (13)C{(1)H} and (1)H NMR spectra of the gel revealed the detailed composition of the components.
  • The gel from 1bCl and alpha-CD contains the corresponding [2]- and [3]pseudorotaxanes, [1b x (alpha-CD)]Br and [1b x (alpha-CD)(2)]Br, while that from 1cBr and alpha-CD consists mainly of [3]pseudorotaxane [1c x (alpha-CD)(2)]Br.
  • Thus, intermolecular interaction between the end groups of the axle component and that between alpha-CDs of the [3]pseudorotaxane contribute to formation of the network.
  • The supramolecular gels were transformed into sols by adding denaturing agents such as urea, C(6)H(3)-1,3,5-(OH)(3), and [py-N-nBu](+)(Cl(-)).

  • [Title] Spatial arrangement of alpha-cyclodextrins in a rotaxane. Insights from free-energy calculations.
  • The rotaxane formed by alpha-cyclodextrins (alpha-CDs) threaded onto a poly(ethylene glycol) (PEG) chain was investigated in the gas phase and in an aqueous solution by means of molecular dynamics simulations.
  • The free-energy difference between the three possible spatial arrangements of consecutive alpha-CD--viz.. head-to-head (HH), head-to-tail (HT), and tail-to-tail, was determined using free-energy perturbation calculations.
  • These simulations reveal that the interaction of alpha-CD with the PEG chain is very similar in the two surroundings, whereas the mutual interaction of the macrocycles is stronger in the gas phase than in the aqueous solution.
  • Analysis of intermolecular hydrogen bonds indicates that hydrogen bonds created between alpha-CD and water molecules weaken the hydrogen-bonding interaction of adjacent alpha-CDs.
  • Comparison of the free-energy differences characteristic of the three possible spatial arrangements of contiguous alpha-CDs reveals that the HH motif of the rotaxane is the most stable in the gas phase due to the hydrogen-bond formation between the secondary hydroxyl groups of the two alpha-CDs, and the slight preference for the HT motif in aqueous solution, which can be related to the directionality of the dipole moment borne by the macrocycles in these two motifs.

  • [Title] Molecular motions of alpha-cyclodextrin on a dodecyl chain studied by molecular dynamics simulations.
  • Motions of an alpha-cyclodextrin (alpha-CD) molecule on a dodecyl chain adopting the all-trans conformation were investigated in the presence of water by molecular dynamics simulations with CVFF force fields, where the trimethylammonium group of dodecyltrimethylammonium bromide (DTAB) is protruded outside the secondary hydroxyl rim of alpha-CD (the secondary-in structure).
  • The alpha-CD molecule shuttled rapidly on the chain without decomplexation.
  • The plane formed by 6 O4 atoms of alpha-CD is most populated between the C6 and C7 atoms of DTAB.
  • The alpha-CD molecule underwent a restricted rotation in a range of 60 degrees with regard to the plane of the dodecyl chain: this plane at the most population is middle between the two diagonal lines of the normal hexagon formed by 6 O4 atoms of alpha-CD.
  • The distortion of the alpha-CD cavity from the normal hexagon was decreased upon complex formation with DTAB.
  • The deviation of the center of alpha-CD from the center of the dodecyl chain predicted by molecular dynamics simulations is consistent with the NMR data.

  • [Title] Formation and self-organization kinetics of alpha-CD/PEO-based pseudo-polyrotaxanes in water. A specific behavior at 30 degrees C.
  • alpha-Cyclodextrins (alpha-CDs) have the ability to form inclusion complexes with poly(ethylene oxide) (PEO) polymer chains.
  • These pseudo-polyrotaxanes (PPRs) can be obtained by quenching an alpha-CD/PEO mixture in water from 70 degrees C down to a lower temperature (typically in the range from 5 to 30 degrees C) thanks to favorable interactions between alpha-CD cavities and PEO chains.
  • Moreover, starting from a liquid alpha-CD/PEO mixture at a total mass fraction of 15% w/w at 70 degrees C, the formation of PPRs with time at a lower temperature induces a white physical gel with time, and phase separation is observed.
  • We established that PPR molecules are exclusively found in the precipitated phase although unthreaded alpha-CD molecules and unthreaded PEO chains are in the liquid phase.
  • At 30 degrees C, we established that, in a first step, alpha-CDs thread onto PEO chains, forming PPR molecules which are not in good solvent conditions in water.
  • At a higher length scale, rapid aggregation of the PPR molecules occurs, and threaded alpha-CD-based nanocylinders form (cylinder length L = 5.7 nm and cylinder radius R = 4.7 nm).
  • At a higher length scale, alpha-CD-based nanocylinders associate in a Gaussian way, engendering the formation of precipitated domains which are responsible for the high turbidity of the studied system.

  • Ground state absorption and steady-state and time-resolved fluorescence measurements have been carried out to understand the host-guest interactions of p-diethylaminobenzonitrile (DEABN) and p-dimethylaminobenzonitrile (DMABN) dyes with alpha-cyclodextrin (alpha-CD) and beta-cyclodextrin (beta-CD) hosts.
  • DEABN and DMABN dyes show both locally excited (LE) state and intramolecular charge transfer (ICT) state emissions in solution.
  • The LE and ICT emissions of the dyes are seen to get modulated in the presence of alpha-CD and beta-CD hosts.
  • The results indicate that the dyes form 1 : 1 inclusion complexes with both the hosts.
  • Comparing the binding constants and the fluorescence characteristics of different dye x CD systems it is inferred that DEABN adopts a completely different orientation on complexation with alpha-CD than in the other cases of dye.CD systems.
  • It is indicated that while in all other cases of dye x CD systems the N,N-dialkyl group of the dyes enters the host cavity leaving the C[triple bond, length as m-dash]N group projected out into the water phase, the DEABN dye enters the alpha-CD cavity (smallest CD) with its C[triple bond, length as m-dash]N group entering the host cavity.
  • The differences in the orientation of the dye in the host cavities is understood to be determined by the requirement of maximum van der Waals contact of the encapsulated dye with the host cavity for maximum stability of the complex and the relative sizes of the substituents of the dye compared to the host cavities.

  • Primary gastro-intestinal lymphoma (PGIL) is the most common type of extra-nodal non Hodgkin's lymphoma.
  • Their clinical and histological presentations are heterogeneous depending on the site of the lesion.
  • In our country epidemiology of the disease is unknown with IPSID being the most frequent type.
  • We report anatomo-clinical features and prognostic factors of PGIL and compare intestinal to gastric forms in our region.
  • Tumor sites were gastric (67%), intestinal (26%) and gastrointestinal (7%).
  • Abdominal pain (87%) followed by vomiting and diarrhoea (37 and 15%) were the most common symptoms.
  • Performance status (PS) < 2 was seen in 80% of patients, high grade lymphoma in 70.5% of cases and B phenotype was noted in 85%.
  • MALT lymphoma accounts for 50% of cases, and IPSID for only 5% of PGIL.
  • Only 46% of patients had surgery (14 for surgical complication, 6 for residual tumor after chemotherapy and 22 to have histological diagnosis).
  • In high grade lymphoma patients favorable prognostic factors for OS included young age < or = 60 years, PS < 2, normal serum LDH, hemoglobin > 12 g/dL, B phenotype, localised stage (IE-IIE1), anthracycline-based chemotherapy regimen, achieving complete or partial response to induction chemotherapy and no relapse.
  • In low-grade lymphoma patients, none of these factors had a significant correlation with OS: age < or = 60 years, PS < 2, stage (IE-IIE1), response to induction chemotherapy, relapse.
  • Compared to gastric lymphomas, intestinal cases occurred at a younger age, frequently with diarrhoea, weight loss, and occlusion.
  • We conclude that stomach is the main site of PGIL in our region, intestinal lymphoma is less frequent and IPSID has become rare.

  • Four smooth muscle myosin heavy chain (SMMHC) isoforms are generated by alternative mRNA splicing of a single gene.
  • We hypothesized that a greater expression of the (+)insert SMMHC isoform and greater regulatory light chain (LC(20)) phosphorylation contribute to airway hyperresponsiveness.
  • We measured airway responsiveness to methacholine in Fischer hyperresponsive and Lewis normoresponsive rats and determined SMMHC isoform mRNA and protein expression, as well as essential light chain (LC(17)) isoforms, h-caldesmon, and alpha-actin protein expression in their tracheae.
  • No difference was found for LC(17) isoform, h-caldesmon, and alpha-actin expression.
  • These results further support the contention that innate airway hyperresponsiveness is a multifactorial disorder in which increased expression of the fast (+)insert SMMHC isoform and greater activation of LC(20) lead to smooth muscle hypercontractility.

  • The self-inclusion behavior and induced circular dichroism (ICD) characteristics of two beta-cyclodextrin (beta-CD) derivatives, in which a 1-methyl-4,4'-bipyridinium (viologen) group is connected by an octamethylene chain to either the primary (2(2+)) or secondary (3(2+)) side of beta-CD, and of their reduced forms, are investigated.
  • 1H NMR studies showed that 2(2+) forms an intramolecular self-inclusion complex with K(in) = 3.1 +/- 0.4, whereas 3(2+) forms a head-to-head type of dimer with K(D) = 65 +/- 10 M(-1) at 25 degrees C. 2(2+) and 3(2+) form [2]pseudorotaxanes with alpha-CD, with the secondary side of the alpha-CD facing the viologen moiety.

  • [Title] Roles of syndecan-1, bcl6 and p53 in diagnosis and prognostication of immunoproliferative small intestinal disease.
  • 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.

  • Cyclic oligomers of glucose, termed cyclodextrins (CDs), can contain 6 (alpha-CD), 7 (beta-CD) or 8 (gamma-CD) glucose units and are able to remove cholesterol from platelet membranes and decrease platelet aggregation.
  • Our results indicate the expected dose-dependent inhibition of platelet aggregation by beta-CD, with no significant effects of alpha-CD or gamma-CD.
  • RBC aggregation studies showed no effect of alpha-CD but highly significant (p<0.01) decreases by both beta-CD and gamma-CD; at the concentrations studied (1.5 x 10(-3) to 1.5 mM), beta-CD had somewhat greater effects.
  • Blood viscosity was not affected by alpha-CD, but was significantly decreased in a dose-dependent manner by beta-CD and, at the highest concentration (1.5 mM), by gamma-CD.

  • An N-Alkyl bipyridinium having a polymethylene chain and a bulky aryl group at the end, [4,4'-bpy-N-(CH2)10OC6H(3)-3,5-tBu2]Cl (Cl), reacts with K[PtCl3(dmso)] to produce the Pt complex with the N-alkyl bipyridinium ligand [Cl2(dmso)Pt{4,4'-bpy-N-(CH2)10OC6H(3)-3,5-tBu2}][PtCl3(dmso)] as a 6:1 mixture of trans and cis isomers ([trans-][PtCl3(dmso)] and [cis-][PtCl3(dmso)]).
  • Addition of alpha-cyclodextrin (alpha-CD) to a solution of Cl in dmso-d6/D2O (3:1) forms [2]pseudorotaxane [{4,4'-bpy-N-(CH2)10OC6H(3)-3,5-tBu2}.(alpha-CD)]Cl (Cl) which is equilibrated with Cl and alpha-CD in solution.
  • The reaction of K[PtCl3(dmso)] with Cl affords the [2]rotaxane [trans-Cl2(dmso)Pt{4,4'-bpy-N-(CH2)10OC6H(3)-3,5-tBu2}.(alpha-CD)][PtCl3(dmso)] ([trans-][PtCl3(dmso)]) which contains alpha-CD and [trans-][PtCl3(dmso)] as the cyclic and axis components, respectively.
  • Dissolution of a mixture of [trans-][PtCl3(dmso)], [cis-][PtCl3(dmso)] and alpha-CD in dmso-d6/D2O (3:1) forms a mixture of the rotaxanes containing [trans--d6][PtCl3(dmso)] and [cis--d6][PtCl3(dmso)].
  • The reaction involves partial dissociation of the bipyridinium from Pt of [trans-][PtCl3(dmso)] or [cis-][PtCl3(dmso)] to yield [PtCl3(dmso)] and formation of pseudorotaxane with alpha-CD, followed by recoordination of the bipyridinium to the Pt.

  • For beta-lap and CD interactions, increasing complexation efficiency was observed in the order of alpha-CD, gamma-CD, and beta-CD. beta-Lap complexation with hydroxypropyl-beta-cyclodextrin (HPbeta-CD) prevented drug dissolution in PLGA, and led to fast release (79.6+/-2.1% after 2 days).
  • Sustained drug release was achieved when beta-lap was complexed with alpha-CD or gamma-CD.

  • Cyclodextrins (CDs) can form a host/guest inclusion complex with bisphenol A(BPA).
  • In the presence of alpha- cyclodextrin or beta-cyclodextrin (alpha-CD or beta-CD), the photodegradation efficiency of BPA can be enhanced, but gamma-cyclodextrin (gamma-CD) showed inhibitive effect on the photodegradation efficiency.
  • The initial degradation rate of BPA firstly increased with increasing concentration of beta-CD and alpha-CD from 0 to 60 micromol L(-1), and the maximum rate was reached at the beta-CD concentration of 60 micromol L(-1), and then decreased.

  • Poly-pseudo-rotaxanes CDs contains as a subset 1 (CDs; cyclodextrins, 1; poly(delta-valerolactone) having single beta-CD at the end of the polymer chain) initiate polymerization of delta-valerolactone (delta-VL) in the solid state when CDs (alpha-CD, beta-CD, and 2,6-di-O-methyl-beta-CD) are threaded onto the polymer chain.
  • The polymer chain of beta-CD contains as a subset 1 was found to elongate in the solid state, whereas the polymer chain of 1 formed a random coil conformation.
  • 1 was deactivated for the polymerization by blocking the active cavity of beta-CD with the polymer chain.
  • CDs threaded onto 1 are immune to the initiation of delta-VL directly but have an essential role to fold the polymer chain in a proper way as an artificial chaperone.

  • [Title] Low-grade B-Cell lymphomas with plasmacytic differentiation lack PAX5 gene rearrangements.
  • The chromosomal translocation t(9;14)(p13;q32) has been reported in association with lymphoplasmacytic lymphoma (LPL).
  • Although this translocation involving the paired homeobox-5 (PAX5) gene at chromosome band 9p13 and the immunoglobulin heavy chain (IgH) gene at 14q32 has been described in approximately 50% of LPL cases, the actual number of cases studied is quite small.
  • Many of the initial cases associated with t(9;14)(p13;q32) were actually low-grade B-cell lymphomas with plasmacytic differentiation other than LPL.
  • Thus, we analyzed a series of low-grade B-cell lymphomas for PAX5 gene rearrangements.
  • We searched records from the Department of Pathology, Stanford University Medical Center for low-grade B-cell lymphomas, with an emphasis on plasmacytic differentiation, that had available paraffin blocks or frozen tissue.
  • We identified 37 cases, including 13 LPL, 18 marginal zone lymphomas (nodal, extranodal, splenic, and alpha-heavy chain disease), and 6 small lymphocytic lymphomas.
  • All cases failed to demonstrate a PAX5 translocation, indicating that t(9;14)(p13;q32) and other PAX5 translocations are uncommon events in low-grade B-cell lymphomas with plasmacytic differentiation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Quantum chemical calculations and molecular dynamics simulations are carried out to study the host-guest inclusion complexes of cyclodextrins (alpha-, beta-, and gamma-CDs) with small guest molecules such as H(2)O, NH(3), NH(4)(+), C(6)H(6), and bisimidazolyl compounds.
  • The uptake ability of the CDs to accommodate the small molecules inside the cavity is examined by the sequential addition of 10 molecules of water or ammonia using the semiempirical (PM3) method.
  • PM3 calculations indicate that alpha-, beta-, and gamma-CD can accommodate three, seven, and nine water molecules, respectively.
  • In the case of NH(3) as guest molecule, alpha-, beta-, and gamma-CDs can accommodate up to two, five, and six molecules, respectively.
  • Semiempirical calculations indicate that two benzene molecules can be accommodated in the alpha-CD cavity, whereas beta- and gamma-CD cavities adopt three and four benzene molecules, respectively.
  • The interaction energies calculated by the MM/PBSA method reveal that ligand 1,6-bis(imidazol-l-lyl) hexane (B) and 1,4-bis(imidazol-l-lylmethyl) benzene (C) molecules prefer to form 1:1 complexes with alpha-, beta-, and gamma-CDs.
  • However, C preferentially forms 1:2 complexes with alpha-CDs.
  • Ligands 1,10-bis(imidazol-l-lyl) decane (A) and 4,4'-(bis(imidazol-l-ylmethylene))biphenyl (D) form 1:2 complexes with alpha-, beta-, and gamma-CDs in head-to-head (HH) orientation of CDs.
  • The stability of inclusion compounds depends on the type of CD and the physicochemical properties of the involved guest.
  • Both of these methods (semiempirical and MD simulations) reveal that beta-CDs form more stable complexes compared with alpha- and gamma-CDs with C, D, NH(4)(+), and C(6)H(6), whereas alpha-CD forms more stable complexes with A and B.

  • [Title] Determination of the binding constant between alprostadil and alpha-cyclodextrin by capillary electrophoresis: implications for a freeze-dried formulation.
  • The binding constant between alprostadil (PGE1) and alpha-cyclodextrin (alpha-CD) was determined at three temperatures by capillary electrophoresis. alpha-CD is an excipient material in Caverject Dual Chamber Syringe (DCS), added to enhance stability.
  • The concentration of PGE1 was fixed while the concentration of alpha-CD was varied over a suitable range.
  • As the amount of PGE1 bound to alpha-CD increases, the weighted average of the resultant mobility decreases, thereby allowing a binding isotherm to be generated from which the stability constant was extracted via nonlinear regression analysis.
  • Po., an earlier-developed product that contains no alpha-CD.

  • This paper reports the working mechanism for a redox-responsive bistable [2]rotaxane incorporating an alpha-cyclodextrin (alpha-CD) ring (J. Am. Chem. Soc.
  • Employing an umbrella sampling technique, the free energy profiles (potential of mean force, PMF) were calculated for the shuttling motion of the alpha-CD ring between a tetrathiafulvalene (TTF) recognition site and a triazole (TZ) unit on the dumbbell of the rotaxane for three oxidation states (0, +1, +2) of the TTF unit.
  • Analysis of the free energy components reveals that, for these alpha-CD-based rotaxanes with charged TTF units, the real driving force for the shuttling in the oxidized states is actually the interactions between water and the rotaxane components, which overwhelms the attractive interactions between the alpha-CD ring and the charged dumbbell.

  • [Title] Hartree-Fock and density functional theory study of alpha-cyclodextrin conformers.
  • Herein, we report the geometry optimization of four conformers of alpha-cyclodextrin (alpha-CD) by means of PM3, HF/STO-3G, HF/3-21G, HF/6-31G(d), B3LYP/6-31G(d), and X3LYP/6-31G(d) calculations.
  • The analysis of several geometrical parameters indicates that all conformers possess bond lengths, angles, and dihedrals that agree fairly well with the crystalline structure of alpha-CD.
  • Among them, conformer 3 appears to be the most stable species both in the gas phase and in solution; therefore, it is expected to be the most suitable representative structure for alpha-CD conformation.
  • Our results indicate that the choice of a particular alpha-CD conformer should affect the results of ab initio computational studies on the inclusion complexation with this cyclodextrin since both the direction and the magnitude of the dipole moment depend strongly on the conformation of alpha-CD.

  • The HIV-1-associated neurocognitive disorder occurs in approximately one-third of infected individuals.
  • Since the cerebrospinal fluid is the most proximal biofluid to the site of pathology, we studied the cerebrospinal fluid in a nonhuman primate model for HIV-1-associated neurocognitive disorder.
  • Here we present a simple and efficient liquid chromatography-coupled mass spectrometry-based proteomics approach that utilizes small amounts of cerebrospinal fluid.
  • Next, using the simian immunodeficiency virus-infected monkey model, we show its efficacy in identifying proteins such as alpha-1-antitrypsin, complement C3, hemopexin, IgM heavy chain, and plasminogen, whose increased expression is linked to disease.
  • This study reveals new central nervous system alterations in lentivirus-induced neurological disease, and this technique can be applied to other systems in which limited amounts of biofluids can be obtained.

  • [Title] Inverse freezing in molecular binary mixtures of alpha-cyclodextrin and 4-methylpyridine.
  • Ternary solutions of alpha-cyclodextrin (alphaCD) in 4-methylpyridine (4MP)/water mixtures solidify when heated and melt when cooled, and the crystalline solid phase exhibits a rich phase behavior as a function of temperature.
  • In this work, we extend these earlier investigations to pure binary mixtures of alphaCD in water free 4MP, characterized via temperature and time dependent measurements of viscosity, X-ray diffraction, and infrared spectroscopy, complemented by observations of acoustic properties and small angle neutron diffraction.

  • To induce ITP, three different strategies were evaluated: (i) Sample self-stacking ensured by the addition of ammonium acetate (NH(4)Ac) to 25-50-fold diluted IL solution (transient ITP). (ii) Complete ITP-ZE separation performed in a single capillary: ITP was realized in discontinuous electrolytes comprising an 80 mM NH(4)Ac, 40 mM acetic acid, 30 mM alpha-CD, pH 5.05, leading electrolyte (LE) and a 10 mM creatinine, 10 mM acetic acid, pH 4.9, terminating electrolyte (TE).
  • This protocol made it possible to accommodate a 2.5-times diluted IL sample. (iii) Complete counterflow ITP-ZE with continuous electrokinetic sample supply: the ITP stage was performed in a capillary filled with a 150 mM NH(4)Ac, 75 mM acetic acid, 30 mM alpha-CD, pH 5.0 LE, with 40-times diluted IL at the capillary inlet.

  • The non-covalent complexes of alpha- and beta-cyclodextrins (alpha-, beta-CDs) with two aryl alkanol piperazine derivatives (Pipe I and Pipe II) have been studied by electrospray ionization mass spectrometry (ESI-MS) and fluorescence spectroscopy.
  • The ESI-MS experimental results demonstrated that Pipe I can conjugate to beta-CD and form 1:1 or 1:2 stoichiometric non-covalent complexes, and Pipe II can only form 1:1 complexes with alpha- or beta-CD.
  • The mass spectrometric titration experiments showed that the dissociation constants K(d1) were 5.77 and 9.52 x 10(-4) mol L(-1) for the complexes of alpha-CD with Pipe I and Pipe II, respectively, revealing that the binding of alpha-CD-Pipe I was stronger than alpha-CD-Pipe II.

  • [Title] Immunoproliferative small intestinal disease in Greece: presentation of 13 cases including two from Albania.
  • 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] Theoretical study of the alpha-cyclodextrin dimer.
  • The molecular structure, stabilization energy, and thermodynamic properties of the plausible modes of the interaction for the three possible alpha-cyclodextrin (alpha-CD) dimers (head-to-head, tail-to-tail, and head-to-tail) with a water cluster were obtained using quantum chemical methods for the first time.
  • The inter alpha-CD hydrogen bonds play a major role to stabilize the dimeric structures, with no water tetramer being found between the two alpha-CD subunits for the preferred global minimum structure.
  • Therefore, a theoretical model aimed to describe the behavior of alpha-CD dimer, or their inclusion complexes, in the aqueous media should take into account this preference for binding of the water molecules.

  • The aim of this study was to investigate the prediction of (14)C-phenanthrene and (14)C-hexadecane biodegradation in the presence of other hydrocarbons in soil using beta- and alpha-cyclodextrin (CD) solutions, respectively.
  • Prediction of (14)C-hexadecane using the alpha-CD extraction was robust under single and co-contaminant conditions (r(2)=0.92, slope of best fit line=0.97, intercept=1.24, n=60); however, the alpha-CD could not accurately predict (14)C-hexadecane biodegradation in the presence of multiple contaminants.

  • [Title] Dietary alpha-cyclodextrin lowers low-density lipoprotein cholesterol and alters plasma fatty acid profile in low-density lipoprotein receptor knockout mice on a high-fat diet.
  • High dietary intake of saturated fat and cholesterol, and elevated low-density lipoprotein cholesterol levels are some of the modifiable risk factors for cardiovascular disease.
  • Alpha-cyclodextrin (a-CD) when given orally has been shown in rats to increase fecal saturated fat excretion and to reduce blood total cholesterol levels in obese hypertriglyceridemic subjects with type 2 diabetes mellitus.
  • At sacrifice, there was no difference in body weight; but significant decreases were observed in plasma cholesterol (15.3%), free cholesterol (20%), cholesterol esters (14%), and phospholipid (17.5%) levels in mice treated with alpha-CD compared with control mice.
  • Furthermore, alpha-CD improved the blood fatty acid profile, reducing the saturated fatty acids (4.5%) and trans-isomers (11%) while increasing (2.5%) unsaturated fatty acids.
  • In summary, the addition of alpha-CD improved the lipid profile by lowering proatherogenic lipoproteins and trans-fatty acids and by decreasing the ratio of saturated and trans-fatty acids to polyunsaturated fatty acids (-5.8%), thus suggesting that it may be useful as a dietary supplement for reducing cardiovascular disease.

  • [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.

  • [Title] Synthesis and characterization of polyrotaxanes consisting of cationic alpha-cyclodextrins threaded on poly[(ethylene oxide)-ran-(propylene oxide)] as gene carriers.
  • Herein, a series of novel cationic supramolecular polyrotaxanes with multiple cationic alpha-cyclodextrin (alpha-CD) rings threaded and blocked on a poly[(ethylene oxide)-ran-(propylene oxide)] (P(EO-r-PO)) random copolymer chain were synthesized and investigated for gene delivery.
  • In the cationic polyrotaxanes, approximately 12 cationic alpha-CD rings were threaded on the P(EO-r-PO) copolymer with a molecular weight of 2370 Da and an EO/PO molar ratio of 4:1, while the cationic alpha-CD rings were grafted with linear or branched oligoethylenimine (OEI) of various chain lengths and molecular weights up to 600 Da.
  • The OEI-grafted alpha-CD rings were only located selectively on EO segments of the P(EO-r-PO) chain, while PO segments were free of complexation.
  • This increased the mobility of the cationic alpha-CD rings and the flexibility of the polyrotaxanes, which enhanced the interaction of the cationic alpha-CD rings with DNA and/or the cellular membrane.
  • All cationic polyrotaxanes synthesized in this work could efficiently condense plasmid DNA to form nanoparticles that were suitable for delivery of the gene.

  • This study has shown for the first time the suitability of CE with a partially aqueous electrolyte system for the analysis of free fatty acids (FFAs) in small portions of single peanut seeds.
  • The partially aqueous electrolyte system consisted of 40 mM Tris, 2.5 mM adenosine-5'-monophosphate (AMP) and 7 mM alpha-CD in (N-methylformamide) NMF/dioxane/water (5:3:2 by volume) mixture, pH 8-9.
  • While AMP served as the background UV absorber for indirect UV detection of the FFAs, the alpha-CD functioned as the selectivity modulator by affecting the relative effective electrophoretic mobilities of the various FFAs due to their differential association with alpha-CD.

  • [Title] Electro membrane extraction combined with capillary electrophoresis for the determination of amlodipine enantiomers in biological samples.
  • Electro membrane extraction as a new microextraction method was applied for the extraction of amlodipine (AM) enantiomers from biological samples.
  • During the extraction time of 15  min, AM enantiomers migrated from a 3  mL sample solution, through a supported liquid membrane into a 20  μL acceptor solution presented inside the lumen of the hollow fiber.
  • The driving force of the extraction was 200  V potential, with the negative electrode in the acceptor solution and the positive electrode in the sample solution.
  • 2-Nitro phenyl octylether was used as the supported liquid membrane.
  • Using 10  mM HCl as background electrolyte in the sample and acceptor solution, enrichment up to 124 times was achieved.
  • Then, the extract was analyzed using CD modified CE method for separation of AM enantiomers.
  • Best results were achieved using a phosphate running buffer (100  mM, pH 2.0) containing 5  mM hydroxypropyl-α-CD.
  • The range of quantitation for both enantiomers was 10-500  ng/mL.
  • Intra- and interday RSD (n=6) were less than 14%.
  • The limits of quantitation and detection for both enantiomers were 10 and 3  ng/mL respectively.
  • Finally, this procedure was applied to determine the concentration of AM enantiomers in plasma and urine samples.
