TL;DR: The present investigation deals with the study of the anti-inflammatory activity of taxifolin, a flavonoid obtained from Madhuca Butyracea, and the effect ofTaxifolin on the serum aminotransferase and tissue adenosine triphosphate (ATP) phosphohydrolase activity to elucidate the possible mechanism of its anti- inflammatory activity.

TL;DR: It was apparent that in addition to a smaller size and better drug release profile, the contribution of other parameters, e.g. overall surface hydrophilicity or hydrophobicity of the vehicles, also play an important role in the macrophage uptake of the drug.
Abstract: The purpose of the present study was to investigate the therapeutic efficacy of the indigenous drug arjunglucoside I (AG) against in vivo models of experimental leishmaniasis by incorporating it in surface hydrophilic co-polymeric nanogel particles of size less than 100 nm diameter and to compare its efficacy with that of the free drug as well as the drug encapsulated in hydrophobic poly-dl-lactide (PLA) nanoparticles. The drug AG, having glucose at the terminal end of the glycosidic chain, was isolated from an indigenous source. Drug-incorporated ultra-low-sized nanogels (∼90 nm in diameter) composed of cross-linked random co-polymer of N-isopropylacrylamide (NIPAAM) and N-vinyl pyrrolidone(VP) were prepared, characterized and used as delivery vehicles to combat experimental leishmaniasis in hamster models. For comparison, drug-encapsulated hydrophobic nanoparticles (∼250 nm in diameter) made from PLA were used as a control. The drug AG was incorporated in these nanocarriers and these drug-nanocarrier co...

TL;DR: Melatonin administration significantly curtailed tumor development and counteracted all the biochemical effects in NDEA‐treated rats.
Abstract: N-nitrosodiethylamine (NDEA) is a potent carcinogenic agent that induces liver cancer. To evaluate the chemopreventive function of melatonin in this experimental model, Wistar male rats received a single i.p. injection of NDEA or vehicle followed by weekly s.c. injections of carbon tetrachloride or vehicle for 6 weeks. Melatonin (5 mg/kg body weight) or its vehicle (0.5 mL saline) was given i.p. on a daily basis 2 hr before lights off for 20 wk. At the end of this period the rats were killed and liver and blood samples were taken for histological and biochemical studies. As markers for liver function, the activity of aspartate transaminase (AST) and alanine transaminase (ALT) and the levels of alpha-fetoprotein were measured in serum. To assess lipid peroxidation and the antioxidant status in liver and blood, the levels of thiobarbituric acid reactive substances (TBARS) and of reduced glutathione (GSH) were measured. The activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione S-transferase (GST) was assessed in liver and erythrocyte fraction of NDEA-treated rats. NDEA administration inhibited body weight, macro- and microscopically detectable liver tumors and increased levels of plasma AST, ALT and alpha-fetoprotein. NDEA treatment decreased liver TBARS levels and CAT and SOD activities and increased liver GSH levels and GST and GPx activities. Plasma TBARS were augmented, while plasma GSH levels and the activities of erythrocyte CAT, SOD, GST and GPx decreased, in NDEA-treated rats. Melatonin administration significantly curtailed tumor development and counteracted all the biochemical effects.

TL;DR: Many aromatic acids, especially those with an unsaturated sidechain, depressed the reaction rates of the enzymes, andound differences in sensitivity were observed with different enzymes.
