What promotes motor recovery from stroke? To date, studies of recovery from stroke have shown alterations in function in various cortical areas, including the contralesional (unaffected) motor cortex (M1). However, whether these changes contribute to recovery or are mere epiphenomena remains unclear. We therefore sought evidence that the ipsilateral M1 can compensate for dysfunction of the cont...

Delamanid, a new anti-tuberculosis drug, is metabolized to M1, a unique metabolite formed by cleavage of the 6-nitro-2,3-dihydroimidazo[2,1-b] oxazole moiety, in plasma albumin in vitro. The metabolic activities in dogs and humans are higher than those in rodents. In this study, we characterized the pharmacokinetics and metabolism of delamanid in animals and humans. Eight metabolites (M1-M8) pr...

Streptococcus pyogenes of the M1 serotype can cause streptococcal toxic shock syndrome and acute lung damage. CD162 is an adhesion molecule that has been reported to mediate neutrophil recruitment in acute inflammatory reactions. In this study, the purpose was to investigate the role of CD162 in M1 protein-provoked lung injury. Male C57BL/6 mice were treated with monoclonal antibody directed ag...

Plasticity of the human primary motor cortex (M1) has a critical role in motor control and learning. The cerebellum facilitates these functions using sensory feedback. We investigated whether cerebellar processing of sensory afferent information influences the plasticity of the primary motor cortex (M1). Theta-burst stimulation protocols (TBS), both excitatory and inhibitory, were used to modul...

Objectives: Corticospinal tract (CST) is the most important tract in motor control. However, there was no study about the change of CST location with aging. In this study, using diffusion tensor tractography (DTT), we attempted to investigate the change of CST location at cortex, corona radiata (CR) and posterior limb of internal capsule (IC) level with aging in typically developing children. M...

The matrix (M1) protein of influenza A virus is a multifunctional protein that plays essential structural and functional roles in the virus life cycle. It drives virus budding and is the major protein component of the virion, where it forms an intermediate layer between the viral envelope and integral membrane proteins and the genomic ribonucleoproteins (RNPs). It also helps to control the intr...

Infections with Streptococcus pyogenes exhibit a wide spectrum of infections ranging from mild pharyngitis to severe Streptococcal toxic shock syndrome (STSS). The M1 serotype of Streptococcus pyogenes is most commonly associated with STSS. In the present study, we hypothesized that Rac1 signaling might regulate M1 protein-induced lung injury. We studied the effect of a Rac1 inhibitor (NSC23766...

Using 24 hours in vitro cultures of rumen microorganisms, this study investigates the effect of buffering capacity of 2 inorganic compounds (M1=119.43 and M2=116.50 meq/L) on the in vitro rumen acidogenic value (AV), medium pH, dry matter disappearance (INVDMD) and methane emission of lactating dairy cow diets containing various forage to concentrate ratios as 40:60 (FC40:60) and 30:70 (FC30:70...

Background & Aims: Aflatoxin M1 is one of the most important toxins present in milk and the product of aflatoxin B1 metabolism in liver microsomes. The aim of this project was to study the aflatoxin M1 adsorption ability of polystyrene-hydroxyapatite nanocomposite. Methods: First, the probability of aflatoxin M1 adsorption by the nanocomposite was evaluated using the HyperChem simulation softwa...

Background & objectives: Aflatoxins are secondary metabolites of fungi and one of the most important types of mycotoxins identified as a carcinogen for humans. The aim of this study was to determine the level of aflatoxin M1 in milk production of dairy factories in east Azerbaijan province by high performance liquid chromatography (HPLC). Methods: In this study, 45 samples of pasteurized milk ...
