The regeneration method of Khorana [J. Biol. Chem. 262 (1987) 9271] has been modified in order to study the effect of endogenous archaeabacterial lipids and, in particular, of glycocardiolipin (GlyC) in the refolding and chromophore regeneration of bacteriorhodopsin (BR). BR refolding and chromophore regeneration could be obtained in the presence of endogenous lipid mixtures containing or not c...

A general model of co-open&iv&y is developed and solved explicitly ; it combines the concepts of preferential binding and quaternary constraints (due to Monod, Wyman & Ghsngeux), nearest-neighbor subunit interactions (due to Koshland), and changes in subunit aggregation (due to Briehl). For this reason, the general model can explain systems which previous models cannot-eg. the model of Monod, W...

purpose: to introduce the importance and world prevalence of ocular leishmaniasis (ol), its clinical manifestations, and diagnostic and management features with more emphasis on iranian cases. methods: we reviewed all available articles published about ol during recent 50 years. results: ol is an ocular protozoal infection which is widespread in the world but is more common in developing countr...

When Chlorella sorokiniana was cultured in the presence of 1 mg/1 triparanol succinate, there was a 42% reduction in total sterol concentration. Algal biomass was reduced by approximately the same amount. In addition to the cycloartenol, cyclolaudenol, 24-methyl-pollinastanol, ergosta-5, 7-dien-3beta-ol, and ergosterol that occur in control culture, pollinastanol, 14alpha-methyl-5alpha-ergost-8...

UNLABELLED The identification of the molecular network that supports oligodendrocyte (OL) regeneration under demyelinating conditions has been a primary goal for regenerative medicine in demyelinating disorders. We recently described an essential function for TACE/ADAM17 in regulating oligodendrogenesis during postnatal myelination, but it is unknown whether this protein also plays a role in OL...

Terpinen-4-ol, a monoterpene component of the essential oils of several aromatic plants, exhibits antitumor effects. In this study, the antitumor effects of terpinen-4-ol and the cellular and molecular mechanisms responsible for it were evaluated and studied, respectively on human nonsmall cell lung cancer (NSCLC) cells. Our results indicated that terpinen-4-ol elicited a dose-dependent cytotox...

This experiment was conducted to investigate the effects of olive leaf (OL) on immune response and some blood metabolites of broiler chickens. A total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. Birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% OL powder from 14 to 4...
