Introduction: Multiple sclerosis is a chronic inflammatory disease of central nervous system. The etiology of MS is slightly known, but genetic and environmental factors are reported. Vitamin D regulates gene expression and affects target cell functions. The aim of this study was to investigate the expression variation of IL-2 and IL-4 genes under vitamin D supplementation in patients with mult...

Background: HOXA11 and leukemia inhibitory factor (LIF) and basic transcriptional element binding protein1 (BTEB1) are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. In this case-control study, the expression pattern of these mRNA was evaluated in patients with endometriosis at the time of implantatio...

Polynomial vector fields which admit a prescribed Darboux integrating factor are quite well-understood when the geometry of the underlying curve is nondegenerate. In the general setting morphisms of the affine plane may remove degeneracies of the curve, and thus allow more structural insight. In the present paper we establish some properties of integrating factors subjected to morphisms, and we...

objective(s): estrogen receptor-alpha (erα) mediates estrogen action in regulation of different levels of the hypothalamic-pituitary-testis axis. it has a key role in spermatogenesis. estrogen receptor alpha knock-out (er koα) male mice were infertile and severe impairment in spermatogenesis and seminiferous tubules was observed. recently, it has been reported that microrna (mirna) mir-100 and ...

Strong gravitational lensing and stellar dynamics provide two complementary and orthogonal constraints on the density profiles of galaxies. Based on spherically symmetric, scale-free, mass models, it is shown that the combination of both techniques is powerful in breaking the mass-sheet and mass-anisotropy degeneracies. Second, observational results are presented from the Lenses Structure & Dyn...

The accelerating expansion of the universe suggests that an unknown component with strongly negative pressure, called dark energy, currently dominates the dynamics of the universe. Such a component makes up ∼ 70% of the energy density of the universe yet has not been predicted by the standard model of particle physics. The best method for exploring the nature of this dark energy is to map the r...

We extract, from a quark model potential that reproduces the number and ordering of nonstrange baryonic resonances up to 2.3 GeV, the quantum numbers for the dominant configurations in the ground and first non-radial excited states. From the pattern of quantum numbers we identify, from data, spectral regularities that allow us to predict the expected high spin low-lying spectrum from 2.3 to 3.0...

background: toll- like receptors (tlrs) play an important role in the recognition of damps and pamps and induction ofinflammation. previous studies demonstrated that depression and anxiety can influence the expression levels of immune related molecules. our previous study revealed that mrna levels of irak4, traf3 and irf7 were significantly decreased in chronic hbv infected (chb) patients when ...

NF-κB pathway is a link between inflammation and cancer and is involved in cellular responses to different stimuli. Gastrointestinal lumen is exposed to many inflammatory agents such as foods, free radicals and bacterial or viral antigens. The aim of the present study was to evaluate the possible role of NF-κB1in gastric adenocarcinoma. To detect the relative level of NF-κB1transcript, total RN...

objective(s): occludin is essential for proper assembly of tight junctions (tjs) which regulate paracellular endothelial permeability. omega-3 polyunsaturated fatty acids (ω-3 pufa) protect endothelial barrier function against injury. materials and methods: we examined anti-inflammatory effect of ω-3 pufa intake (30 mg/kg/day for 10 days) on expression and location of occludin in the aorta of a...
