The cerebellum is crucially important for motor control and adaptation. Recent non-invasive brain stimulation studies have indicated the possibility to alter the excitability of the cerebellum and its projections to the contralateral motor cortex, with behavioral consequences on motor control and adaptation. Here we sought to induce bidirectional spike-timing dependent plasticity (STDP)-like mo...
Macrophage/microglia with heterogonous phenotype and function under physiological and pathological conditions are the main cell lineage involved in inducing immune responses in neuroinflammatory diseases which exhibit combined inflammatory and anti-inflammatory functions. An increase in the expression of iNOS triggers M1 phenotype that secrete high concentrations of inflammatory cytokines, whil...
آفلاتوکسینها گروهی از مایکوتوکسینها هستند که توسط قارچهایی بنام آسپرژیلوس فلاوس، آسپرژیلوس پارازیتیکوس و آسپرژیلوس نومیوس تولید میشوند. آفلاتوکسین M1 متابولیت اصلی آفلاتوکسین B1 میباشد و این سم هپاتوتوکسیک و سرطانزا میباشد. هدف از این مطالعه تعیین میزان آلودگی شیر خام گاو با آفلاتوکسین M1 در شهر تبریز بود. برای این مطالعه 90 نمونه شیر خام گاو از مراکز جمعآوری شیر اطراف شهر تبریز از ت...
The ventral premotor area (F5) is part of the cortical circuit controlling visuomotor grasp. F5 could influence hand motor function through at least two pathways: corticospinal projections and corticocortical projections to primary motor cortex (M1). We found that stimulation of macaque F5, which by itself evoked little or no detectable corticospinal output, could produce a robust modulation of...
Streptococcus pyogenes of the M1 serotype can cause STSS, which is associated with significant morbidity and mortality. The purpose of the present study was to examine the role of NFAT signaling in M1 protein-induced lung injury. NFAT-luc mice were treated with the NFAT inhibitor A-285222 before administration of the M1 protein. Neutrophil infiltration, edema, and CXC chemokines were quantified...
OBJECTIVE This study proposes more objective methods for deciding the appropriate direction of the sylvian fissure dissection during surgical clipping in middle cerebral artery (MCA) bifurcation aneurysms. METHODS We reviewed data of 36 consecutive patients with MCA bifurcation aneurysms. We measured 2 indices preoperatively on 3-dimensional computed tomography angiography (3D-CTA). Analysis ...
BACKGROUND Postsynaptic cholinergic deficits, including reduced cortical muscarinic M1 receptor coupling to G-proteins, are neurochemical findings postulated to underlie the limited efficacy of presynaptically-targeted cholinergic replacement therapies in Alzheimer's disease (AD). While the loss of M1-G-protein coupling has been associated with β-amyloid (Aβ) burden in AD, the status of M1 coup...
The Nef-M1 peptide competes effectively with the natural ligand of CXC chemokine receptor 4 (CXCR4), stromal cell-derived factor 1-alpha, to induce apoptosis and inhibit growth in colon cancer (CRC) and breast cancer (BC). Its role in tumor angiogenesis, and epithelial-to-mesenchymal transition (EMT) regulation, key steps involved in tumor growth and metastasis, are unknown. We evaluated the an...
A graph G is k-linked if G has at least 2k vertices, and for every sequence x1, x2, . . . , xk, y1, y2, . . . , yk of distinct vertices, G contains k vertex-disjoint paths P1, P2, . . . , Pk such that Pi joins xi and yi for i = 1, 2, . . . , k. Moreover, the above defined k-linked graphG is k-linked modulo (m1,m2, . . . ,mk) if, in addition, for any ktuple (d1, d2, . . . , dk) of natural number...
Background: Genetic polymorphisms of cytochrome p450 in humans are the main cause of differences in the metabolism. The allele and genotype frequencies of CYP2C19 and CYP2C9 have been studied in some Iranian populations. The aim of present study was to examine the frequencies of CYP2C18m1, and CYP2C18m2, alleles in the Mazandarani ethnic group among Iranian Population. Materials and Methods: I...
