We examine the stability of mixed-symmetry superconducting states with broken time-reversal symmetry in spatial-symmetry-broken systems, including chiral states, on basis free-energy functional derived weak-coupling theory. consider a generic α1 + iα2 wave state, and α2 being different indices such as \((\alpha _{1},\alpha _{2}) = (\text{d},\text{s})\), \((\text{p}_{x},\text{p}_{y})\), \((\text...
BACKGROUND AMP protein kinase (AMPK) plays an important role in food intake and energy metabolism, which are synchronized to the light-dark cycle. In vitro, AMPK affects the circadian rhythm by regulating at least two clock components, CKIα and CRY1, via direct phosphorylation. However, it is not known whether the catalytic activity of AMPK actually regulates circadian rhythm in vivo. METHODO...
To explore the mechanism behind slow dynamics of the glass transition is an interesting topic from a statistical physical point of view [1, 2]. One of characteristic dynamical properties in glass-forming systems is described by a non-Gaussian parameter α2(t) [3], which is related to the mean-square and –fourth displacements, M2(t) and M4(t), through the relation α2(t)=3M4(t)/5M2(t)-1. It has a ...
The synthesis, electronic spectral, and photophysical properties of a new bithiophene derivative, (2,2′-bithiophene)-3,5,5′-trisulfonic acid, α2-SO3H, were investigated in organic or aqueous soluti...
Ca2+ channels are voltage-gated ion present in the membrane of most excitable cells. The nomenclature for Ca2+channels was proposed by [131] and approved NC-IUPHAR Subcommittee on [72]. Most form hetero-oligomeric complexes. α1 subunit is pore-forming provides binding site(s) practically all agonists antagonists. 10 cloned α1-subunits can be grouped into three families: (1) high-voltage activat...
مقدمه: چاقی عامل خطرساز مهم برای بیماری هایی مانند دیابت، پرفشاری خون، هیپرلیپیدمی، بیماری های قلبی ـ عروقی و برخی انواع بدخیمی هاست. به علاوه چاقی با مقاومت به انسولین و هیپرانسولینمی همراه است. هورمون ها و سیتوکینهایی همچون لپتین وtnf-αکه به وسیله بافت آدیپوز تولید می شوند، در ایجاد مقاومت به انسولین ناشی از چاقی نقش مؤثری دارند. هدف از این تحقیق بررسی اثر تجویز محیطی یوهیمبین (آنتاگونیست ...
To follow human milk oligosaccharide (HMO) biosynthesis and in vivometabolization, mother infant feces from 68 mother–infant dyads at 2, 6, 12 weeks postpartum were analyzed, with 18 major HMOs quantitated. Fucosylated neutral core HMO levels dependent on mothers’ Lewis/Secretor status, whereas most sialylated independent. Infant fecal excretion of gradually declined age, especially for structu...
Background: Intense stress can change pain perception and induce hyperalgesia; a phenomenon called stress-induced hyperalgesia (SIH). However, the neurobiological mechanism of this effect remains unclear. The present study aimed to investigate the effect of the spinal cord µ-opioid receptors (MOR) and α2-adrenergic receptors (α2-AR) on pain sensation in rats with SIH. Methods: Eighteen Sprague-...
On most adrenergic and cholinergic nerve terminals, prejunctional α-adrenoceptors belonging to the α2-subtype have been identified. Activation of these receptors will decrease the release of norepinephrine. It has been reported that several isolated tissue preparations contain prejunctional dopamine receptors, the stimulation of which inhibits neurotransmission. It has remained uncertain whethe...
