Ketone bodies are the most energy-efficient fuel and yield more ATP per mole of substrate than pyruvate and increase the free energy released from ATP hydrolysis. Elevation of circulating ketones via high-fat, low-carbohydrate diets has been used for the treatment of drug-refractory epilepsy and for neurodegenerative diseases, such as Parkinson's disease. Ketones may also be beneficial for musc...
A rapid and reproducible method for the assay of 14C radioactivity in ketone bodies is described, based on the heat lability of acetoacetate and the ability of beta-hydroxybutyrate to quantitatively bind to and elute from an ion exchange resin. Potential interference from 14C activity in the ketone body metabolites (CO2, bicarbonate and acetone) during infusion of 14C-labeled ketone bodies is e...
Traditionally, the ketone body β-hydroxybutyrate (βOHB) has been looked upon as a carrier of energy from liver to peripheral tissues during fasting or exercise. However, βOHB also signals via extracellular receptors and acts as an endogenous inhibitor of histone deacetylases (HDACs). These recent findings support a model in which βOHB functions to link the environment, in this case the diet, an...
in the present work a ph-dependent cloud point extraction procedure using ph-sensitive hydrogel polymer was applied for preconcentration and spectrophotometric determination of the hg(ii) as its thio micher's ketone complex. central composite design (ccd) and response surface method were applied to design the experiments and find out the optimum conditions. four factors entitled concentration o...
چکیده قاجارها و حکومت پهلوی اول علی بازوند موضوع انقراض سلسله قاجار و انتقال حکومت به پهلوی از رخدادهای مهم تاریخ معاصر ایران است . که در این پژوهش به چگونگی نقش و عملکرد دیوان سالاران ، شاهزادگان و رجال خاندان قاجاری در این انتقال قدرت و نحوه ی برخورد رضاشاه با قاجارها دردوران سلطنت به آن پرداخته شده است . برای پاسخ به این مسأله ، بررسی های انجام گرفته بیانگر آن است که مخالفت افراد قاج...
Background and Objectives: Cigarette smoke contains carcinogenic compounds, including nicotine-derived nitrosamine ketone (NNK), which can activate vascular endothelial growth factor (VEGF) and increase the inflammation of the lung. Since the Nigella sativa plays an important role in treating cancer through the modification of cellular signaling pathways, the purpose of this study was dete...
The paper describes the modification conducted for PAN carbon fiber surfaces in solutions of nitric and sulphuric acids. authors studied impact parameters such as temperature, acid concentration, time ratio nitrosulphuric on occurrence reactive groups surface. revealed presence carboxylic ketone range 1663-1798 1568 cm -1 IR spectra fibers. use did not identify sulfur-containing functional spec...
