Endoplasmic reticulum stress (ERS) in adipocytes can modulate adipokines secretion. The aim of this study was to explore the protective effect of high-density lipoprotein (HDL) on oxidized low-density lipoprotein (ox-LDL)-induced ERS-C/EBP homologous protein (CHOP) pathway-mediated adipokine secretion. Our results showed that serum adipokines, including visfatin, resistin and TNF-α, correlated ...

BACKGROUND/AIMS Oxidized low-density lipoprotein (ox-LDL) is a powerful atherogen. Toll-like receptor 4 (TLR4) has a pathophysiological role in regulating inflammatory responses and atherosclerosis. Mast cells can infiltrate into the atheromatous plaque and secrete various pro-inflammatory cytokines, which significantly amplify the atherogenic processes and promote plaque vulnerability. Small i...

Much of the understanding of the hypocretin/orexin (HCRT/OX) system in sleep-wake regulation came from narcolepsy-cataplexy research. The neuropeptides hypocretin-1 and -2/orexin-A and -B (HCRT-1 and -2/OX-A and -B, respectively), as we know, are intimately involved in the regulation wakefulness. The HCRT/OX system regulates sleep-wake control through complex interactions between monoaminergic/...

To investigate the role of T-helper cells/Treg (Th17/Treg) and morbidity factors related to primary nephritic syndrome (PNS) in children, as well as the influence of ox-low density lipoprotein (ox-LDL) on Th17/Treg expression in children with PNS. To clarify the pathogenesis of PNS in children, 50 children with PNS treated in our hospital were enrolled in the study group. Additionally, 20 healt...

Haemoglobin damaged by exposure of red blood cells to oxidants is rapidly degraded by a proteolytic pathway which does not require ATP [Fagan, Waxman & Goldberg (1986) J. Biol. Chem. 261, 5705-5713]. By fractionating erythrocyte lysates, we have purified two proteases which hydrolyse oxidatively damaged haemoglobin (Ox-Hb). One protease hydrolysed small fluorogenic substrates in addition to Ox-...

This study was designed to investigate the apoptosis induced by oxidized low-density lipoprotein (ox-LDL) in cultured neonatal rat cardiomyocytes and explore the possible mechanisms. We evaluated whether ox-LDL-induced apoptosis depended in part on the activation of toll-like receptor-4(TLR4)/Nuclear factor κB (NF-κB) signaling pathway. Cells were cultivated with and without ox-LDL. Cell apopto...

Background & Aim:Iranian ox-tongue (Echium amoenum Fisch. & Mey.) is an endemic Iranian medicinal plant belongs to Boraginaceae family. The violet-blue petals of this plant have been used in traditional medicine. Drying is one of the most critical and fundamental operations in the post-harvest processing of medicinal plants. Experimental: This re...

Objectives: Immobilization effects on antioxidant enzymes activities, red-ox variables and rheological parameters of erythrocytes were studied. Background: It is not clear to which extent immobilization-induced oxidative stress may affect erythrocyte rheology. Method: Hematological and red-ox variables, erythrocyte antioxidant enzymes activities, and rheologic parameters of erythrocytes were an...

Note that the map π is equivariant under the Gm-action, where the Gm-action on A2 is by dilation. When k is a field of positive characteristic, for simplicity, we denote A2n(1) simply by V and denote Hilb(A2)(1) by X. As has been explained in [Vain14], for any integral weight λ of G, on X there is a quantization OX , coming from quantum Hamiltonian reduction of D(g⊕ An), the sheaf of differenti...
