The content of MMT was estimated by thermal gravimetric analysis. The drug encapsulation efficiency and in vitro drug release kinetics were measured

by high-performance liquid chromatography. The size, size distribution, surface charge and morphology of the exemestane-loaded nanoparticles were characterized using a Zetasizer Nano ZS and field emission scanning electron microscopy. The physical status of exemestane in the nanoparticles was characterized by differential scanning calorimetry. In vitro cellular uptake of coumarin-6-loaded nanoparticles was investigated by confocal laser scanning microscope, demonstrating that the fluorescence nanoparticles were internalized by Caco-2 cells (as an in vitro gastrointestinal model). The results of in vitro cytotoxicity experiment on MCF-7 cells (as a model of breast cancer cells) showed Proteasome inhibitor the exemestane-loaded nanoparticles resulted in lower cell viability versus the pure exemestane solution. The cytotoxicity against MCF-7 cells for exemestane-loaded nanoparticles and pure exemestane solution

was dependent on the drug concentration and incubation time. In conclusion, this study indicates the capability of PLGA nanoparticles and PLGA/MMT nanoparticles in enhancing the oral delivery of exemestane.”
“We present a 57-year-old man who worked in a pediatric setting who, after a strong coughing attack caused by a pertussis infection, presented with an internal carotid dissection and a consequent ischemic cerebral lesion. This case suggests the importance of vaccination Saracatinib mouse for subjects who belong to high-risk categories.”
“A new epoxidic ganoderic acid, 8 alpha,9 alpha-epoxy-3,7,11,15,23-pentaoxo-5 alpha-lanosta-26-oic acid (1), together with the known compounds 3 beta-hydroxy-7,11,15,23-tetraoxo-5

alpha-lanosta-8-en-26-oic acid (2), ergosta-7,22-diene-3 beta-yl pentadecanoate (3), ergosta-7,22-diene-3 beta-ol (4), beta-sitosterol (5), fatty acids (6-10), fatty acid ester (11) and octadecane (12) were isolated from the fruiting bodies of Ganoderma lucidum from south India. Their structures were determined by (1)H, (13)C, (13)C DEPT, (1)H-(1)H COSY, HMBC, HSQC, NOESY NMR, FT-IR, UV-vis and FABMS spectral analysis. Compounds Apoptosis inhibitor (1-3) exhibited good antifungal activity against Candida albicans in disc diffusion assay (100 mu g/disc). Steroid ester (3) showed moderate anti-inflammatory activity (59.7% inhibition, 100 mg/kg body weight) in carrageenan-induced paw edema. (C) 2011 Phytochemical Society of Europe.

“Sulfur mustard (SM) is a bifunctional alkylating agent with strong blistering, irritant, mutagenic and cytotoxic properties. SM has been widely deployed as a chemical warfare agent for over a century, leading to extensive casualties. Skin is among the first and most heavily damaged organs upon SM exposure. Unfortunately, a considerable fraction of SM-intoxicated patients are still suffering from chronic cutaneous complications.
