Background Citrullus colocynthis (CCT) is used as the anti-diabetic and antioxidant agent. Polycystic ovarian syndrome (PCOS) is a reproductive disorder which level of gonadotropins and sexual hormones are imbalanced. Objective We evaluated the effect of CCT hydro-alcoholic extract on hormonal and folliculogenesis process in estradiol valerate-induced PCOs rats' model. Materials and Methods...

Aim of the study : To compare the efficacy and tolerability of various topical therapies like short contact Lipsomal dithranol ointment, 0.1% Betamethasone valerate ointment and liquid paraffin for psoriasis. Materials and Methods: This study was conducted in dermatology department of a tertiary hospital and a total of sixty patients who attended the Psoriasis clinic were randomly allocated to ...

CoSBA-xAl catalysts show a high yield in the levulinic acid conversion into ethyl valerate. This is due to presence of weak Lewis sites associated with Co2+ species that have been stabilized by incorporation Al support.

The interaction of three anthracycline drugs, daunomycin, Adriamycin, and N-trifluoroacetyladriamycin 14-valerate, with mouse peritoneal macrophages was explored. As assessed by drug-specific cytofluorescence, Adriamycin and daunomycin accumulated slowly within macrophages, first staining the nucleus and then the cytoplasmic inclusions that were induced by the drug treatment. N-Trifluoroacetyla...

There is currently great interest in developing radiolabeled substrates for acetylcholinesterase and butyrylcholinesterase that would be useful in the in vivo imaging of patients with Alzheimer's disease. Using a simple in vitro spectrophotometric assay for determination of enzymatic cleavage rates, the structure-activity relationship for a short series of 1-methyl-4-piperidinyl esters was inve...

Heat inactivation was studied at 45, 50, 55, and 60 degrees for all of the phenyl valerate hydrolases (PVase), including neurotoxic esterase (NTE) and inhibitor-resistant esterase (IRE), in homogenates of hen or rat brain or in preparations of hen brain microsomal membranes. Hen and rat brain homogenates were prepared in buffer (50 mM Tris/0.20 mM EDTA, pH 8.00, at 25 degrees). Hen brain micros...

Mutants of Escherichia coli K-12 which grow on butyrate and valerate were studied with respect to uptake of these substrates. To utilize short-chain and medium-chain fatty acids, E. coli must synthesize the beta-oxidation enzymes constitutively. In addition, growth on the C(4) and C(5) acids requires a second mutation which permits entry of these substrates. At pH 5, both in the parent and muta...
