Exogenous neuregulin-1 attenuates STZ-induced diabetic peripheral neuropathic pain in rats

Acta cir. bras; 32 (1), 2017
Abstract Purpose: To investigate whether modulating NRG1 could attenuate diabetic neuropathic pain and analyze the underlying mechanism. Methods: Male SD rats were randomly divided into control group, diabetic group, NRG1 intervention group. After STZ-induced 2 weeks, NRG1 intervention daily for consec...

Effect of miR-125b on dermal papilla cells of goat secondary hair follicle

Background: MicroRNAs (miRNAs) are endogenous noncoding RNAs that regulate various biological processes. miR-125b is a miRNA that has been reported to be critical for hair follicle (HF) morphogenesis and development. We identified that the expression of miR-125b varies during an individual hair cycle (an...

Etanercept protects rat cardiomyocytes against hypertrophy by regulating inflammatory cytokines secretion and cell apoptosis

Braz. j. med. biol. res; 50 (6), 2017
We aimed to investigate the effect of etanercept, a tumor necrosis factor-α (TNF-α) inhibitor, on rat cardiomyocyte hypertrophy and its underlying mechanism. Primary neonatal rat cardiomyocytes were isolated from Sprague-Dawley rats. The model of rat cardiomyocyte hypertrophy was induced by end...

Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss

Abstract This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57...

Effect of fresh frozen plasma on the in vitro activation of U937 monocytes: a potential role for the age of blood donors and their underlying cytokine profile

Biol. Res; 50 (), 2017
BACKGROUND: Fresh frozen plasma (FFP) administration may increase the risk of nosocomial infections in parallel with the development of immune modulation. This could be driven by soluble mediators, possibly influencing the in vitro activation of human U937 monocyte cells, in a manner dependent on the age...

Anti-inflammatory effect of lycopene on endotoxin-induced uveitis in rats

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: We evaluated the efficacy of lycopene, a dietary carotenoid and potent antioxidant, against ocular inflammation and oxidative stress in an experimental uveitis model. Methods: Endotoxin-induced uveitis (EIU) was induced in Sprague-Dawley rats by a single subcutaneous injection of 200 ...

18F-Fluorodeoxyglucose positron emission tomography and serum cytokines and matrix metalloproteinases in the assessment of disease activity in Takayasu's arteritis

Rev. bras. reumatol; 56 (4), 2016
ABSTRACT Objective: To evaluate 18F-fluorodeoxyglucose (18F-FDG) uptake on positron emission tomography–computed tomography (PET–CT) and serum levels of different cytokines and matrix metalloproteinases (MMPs) in patients with Takayasu arteritis (TA) and associations with disease activity. ...

The acute effects of preoperative ozone theraphy on surgical wound healing

Acta cir. bras; 31 (7), 2016
ABSTRACT PURPOSE: To investigate the effects of preoperative rectal ozone insufflation on surgical wound healing over the proinflammatory cytokines and histopathological changes. METHODS: Twenty one rabbits were divided into 3 groups. Sham, surgical wound, and ozone applied (6 sessions, every other day...

Serum concentrations and renal expressions of IL-1 and TNF-a early after hemorrhage in rats under the effect of glibenclamide

Acta cir. bras; 31 (7), 2016
ABSTRACT PURPOSE: To investigate changes in the serum concentration and renal expression of IL-1 and TNF-α cytokines in rats that received sevoflurane and glibenclamide prior to hemorrhage. METHODS: Two groups of sevoflurane-anesthetized Wistar rats (n=10): G1 (control) and G2 (glibenclamide, 1 Â...

Host inflammatory response to polypropylene implants: insights from a quantitative immunohistochemical and birefringence analysis in a rat subcutaneous model

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Objectives To describe acute and sub acute aspects of histological and immunohistochemical response to PP implant in a rat subcutaneous model based on objective methods. Materials and Methods Thirty rats had a PP mesh subcutaneously implanted and the same dissection on the other side of abdo...
