Comparative molecular dynamics simulations of n-octyl-beta-D-galactopyranoside (beta-C8Gal) and n-octyl-beta-D-glucopyranoside (beta-C8Glc) micelles in aqueous solution have been performed to explore the influence of carbohydrate stereochemistry on glycolipid properties at the atomic level. In particular, we explore the hypothesis that differences in T(m) and T(c) for beta-C8Gal and beta-C8Glc ...

Cyclodextrin-based host-guest chemistry has been exploited to facilitate co-crystallization of recombinant human acid β-glucosidase (β-glucocerebrosidase, GlcCerase) with amphiphilic bicyclic nojirimycin analogues of the sp(2)-iminosugar type. Attempts to co-crystallize GlcCerase with 5-N,6-O-[N'-(n-octyl)iminomethylidene]nojirimycin (NOI-NJ) or with 5-N,6-S-[N'-(n-octyl)iminomethylidene]-6-thi...

background & aim: a simple and rapid microwave- assisted extraction (mae) procedure was developed and optimized for the isolation of borneol and bornyl acetate from ferulago macrocarpa. ferulago macrocarpa (apiaceae) is an endemic plant in iran. experimental: dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a clevenger extraction approach under opt...

background: there are controversial reports about the exact mechanisms of lead-induced hypertension, but many factors such as alteration in the responsiveness of cardiovascular system to endogenous substances including catecholamines could be one of the mechanisms involved. in present study, the effect of exposure to 100 ppm lead acetate by drinking water (in the periods of 4, 8 and 12 weeks) o...

abstract— in the present study, genetic programming (gp) as a completely different approach in comparison with conventional methods, based on the imitation of natural evolution of living organism is proposed for the prediction of cellulose acetate (ca) polymeric membrane characteristics. the membrane preparation parameters of polymer concentration, additive concentration and coagulation bath te...

introduction: wistar rats are an outbred strain of albino rats belonging to the species rattus norvegicus. histopathological studies on the testis was carried out to determine the effects of heat and lead on male fertility by evaluating some andrological parameters of the wistar rat such as morphology of spermatozoa, sperm count and motility. the main objective of this research was to compare t...

We describe a newly designed technique for the quick, easy, and cost-effective fixation of mesh skin grafts in a range of skin conditions and patients. We fixed the skin graft using octyl-2-cyanoacrylate (Dermabond; Ethicon), which was termed "Dendritic bonding." This technique exhibits several advantages over surgical stapling and suturing with absorbable sutures.

objective to determine and compare the spf (sun protection factor) and moisturizing effects of the liposomal and conventional lotion formulations containing octyl methoxycinnamte (omc) as a sunscreen by in vivo methods. materials and methods the multilamellar liposomes (mlvs) containing omc were prepared by fusion method and o/w emulsion was prepared as fda standard sunscreen method. the spfs o...

calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. in this study, various formulations of calcium acetate tablets were prepared and their disintegrati...

cyproterone acetate (ca) has been loaded to liposome by solvent evaporation and thin film formation technique. the effects of some formulation variables such as temperature of organic solvent evaporation, rotary evaporator speed, volume of organic solvent, volume of balloon and temperature of hydrating buffer has been evaluated. the data showed that bigger balloon with higher surface area has b...
