The aim of the present work was to develop ellagic acid (EA) loaded poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles for oral administration. PLGA nanoparticles were prepared by a method based on the concept of emulsion-diffusion-evaporation by using polyethylene glycol (PEG) 400 as a cosolvent for solubilizing the drug. While developing this method,(More)
Voltage-gated L-type Ca(2+) (Ca(v)1.2) channels in vascular smooth muscle cells are a predominant Ca(2+) influx pathway that mediates arterial tone. Channel biogenesis is accomplished when the pore-forming α(1C) subunit coassembles with regulatory Ca(v)β subunits intracellularly, and the multiprotein Ca(v)1.2 channel complex translocates to the plasma(More)
Caloric restriction (CR) is the most compelling example of lifespan extension by external manipulation. Although the molecular mechanisms remain unknown, the theory of hormesis has been invoked to explain the life promoting effects of CR. Hormesis is defined as the beneficial effects of low intensity stressor on a cell or organism. Mrg19 is a putative(More)
RATIONALE Calcium channel blockers (CCBs) exert their antihypertensive effect by reducing cardiac afterload but not preload, suggesting that Ca(2+) influx through L-type Ca(2+) channels (LTCC) mediates arterial but not venous tone. OBJECTIVE The object of this study was to resolve the mechanism of venous resistance to CCBs. METHODS AND RESULTS We(More)
Inward rectifier potassium (Kir) channels play fundamental roles in cardiac and renal function and may represent unexploited drug targets for cardiovascular diseases. However, the limited pharmacology of Kir channels has slowed progress toward exploring their integrative physiology and therapeutic potential. Here, we review recent progress toward developing(More)
Diuretics acting on specific nephron segments to inhibit Na+ reabsorption have been used clinically for decades; however, drug interactions, tolerance, and derangements in serum K+ complicate their use to achieve target blood pressure. ROMK is an attractive diuretic target, in part, because its inhibition is postulated to indirectly inhibit the(More)
The vitamin E analogs δ-tocotrienol (DT3) and γ-tocotrienol (GT3) have significant protective and mitigative capacity against the detrimental effects of ionizing radiation (IR). However, the expense of purification limits their potential use. This study examined the tocotrienol-rich fraction of rice bran (TRFRB) isolated from rice bran deodorizer(More)
The inward rectifier potassium (Kir) channel Kir7.1 (KCNJ13) has recently emerged as a key regulator of melanocortin signaling in the brain, electrolyte homeostasis in the eye, and uterine muscle contractility during pregnancy. The pharmacological tools available for exploring the physiology and therapeutic potential of Kir7.1 have been limited to(More)
ATP-sensitive potassium (KATP) channels play fundamental roles in the regulation of endocrine, neural and cardiovascular function. Small-molecule inhibitors (e.g., sulfonylurea drugs) or activators (e.g., diazoxide) acting on SUR1 or SUR2 have been used clinically for decades to manage the inappropriate secretion of insulin in patients with Type 2 diabetes,(More)
