محاسبه دز جذبی در اندام انسان یکی از اولین گامها برای توسعه رادیوداروهای جدید است. هدف این مطالعه تخمین توسط ترکیب نوین نشاندار Cu-NODAGA-RGD-BBN64 بدینمنظور ابتدا با تغییر پارامترهای مؤثر بر نشاندارسازی شرایط بهینه تهیه شد. پایداری پپتید هترودیمر بافر سالین فسفات (PBS) و سرم خون انسانی به مدت 12 ساعت ارزیابی پس آن، توزیع زیستی کمپلکس موشهای حامل تومور تزریق مورد بررسی قرار گرفت. نهایت، اسا...
PURPOSE The aim of this study was to analyze patterns of sensory protein expression and urothelial dysfunction in ketamine-related cystitis (KC) in humans. METHODS Biopsies of bladder mucosa were performed in 29 KC patients during cystoscopy. Then specimens were analyzed for tryptase, zonula occludens-1 (ZO-1), E-cadherin, and terminal deoxynucleotidyl transferase-mediated dUTP nick end-label...
P2X receptors (P2XR) function as ATP-gated nonselective ion channels permeable to Na+, K+, and Ca2+, and they are expressed in a wide range of excitable, epithelial/endothelial, and immune effector cell types. The channels are trimeric complexes composed of protein subunits encoded by seven different P2XR genes expressed in mammalian and other vertebrate genomes. Current genetic, biochemical, a...
N-Glycosylation affects the function of ion channels at the level of multisubunit assembly, protein trafficking, ligand binding and channel opening. Like the majority of membrane proteins, ionotropic P2X receptors for extracellular ATP are glycosylated in their extracellular moiety. Here, we used site-directed mutagenesis to the four predicted N-glycosylation sites of P2X(3) receptor (Asn(139),...
A novel in vitro intra-arterially perfused adult rat tongue-nerve preparation was used to explore the possible actions of P2X purinoceptor agonists (ATP and alpha,beta-methylene ATP (alpha, beta-meATP)) on sensory nerve terminals innervating the rat tongue. We made whole-nerve recordings of the trigeminal branch of the lingual nerve (LN), which conducts general sensory information (pain, temper...
