Urinary tract infections are most commonly caused by uropathogenic strains of Escherichia coli (UPEC), which invade superficial bladder epithelial cells via a type 1 pilus-dependent mechanism. Inside these epithelial cells, UPEC organisms multiply to high numbers to form intracellular bacterial communities, allowing them to avoid immune detection. Bladder epithelial cells produce interleukin-6 ...

Microsomal prostaglandin E synthase-1 (mPGES-1) is a recently characterized cytokine-inducible enzyme critically involved in pain and inflammatory response. However, its role in blood pressure regulation is still debatable. The present study was undertaken to examine the effect of mPGES-1 deletion on DOCA-salt hypertension. After 2 weeks of DOCA plus 1% NaCl as drinking fluid, hypertension and ...

Among commercially available urinary human menopausal gonadotrophin (HMG) material, gonadotrophins comprise <5% of the total protein content. Thus, during a typical ovarian stimulation cycle with HMG, several milligrams of non-relevant proteins are administered that may lead to unwanted side effects, including allergic or other hypersensitivity reactions. The effects of two recombinant and four...

Uropathogenic Escherichia coli (UPEC) is a causative agent in the vast majority of urinary tract infections (UTIs), including cystitis and pyelonephritis, and infectious complications, which may result in acute renal failure in healthy individuals as well as in renal transplant patients. UPEC expresses a multitude of virulence factors to break the inertia of the mucosal barrier. In response to ...

α-haemolysin (HlyA)-producing Escherichia coli commonly inflict severe urinary tract infections, including pyelonephritis, which comprises substantial risk for sepsis. In vitro, the cytolytic effect of HlyA is mainly mediated by ATP release through the HlyA pore and subsequent P2X1/P2X7 receptor activation. This amplification of the lytic process is not unique to HlyA but is observed by many ot...

results at the end of the study, four 4 cases in the nelatone group and 12 cases in the foley group presented with uti (p = 0.01). no positive urine cultures were found in the control group. conclusions the nelatone catheters, compared with the foley ones, had a lower risk of uti in the long term use. verifying this claim by further studies can have an important role in reducing utis in patient...

atopic dermatitis (ad) is a common chronically relapsing skin disease associated with abnormal cytokine production, and activation of t-helper 2 cells. the aim if this study was to determine whether cytokine gene polymorphisms might influence the development of ad. single nucleotide polymorphisms in the genes for i-l1alpha, il-1beta, il-1r, il-2, il-4, il-6, il-10, il-12, tgf beta, tnf and ifng...

background: because of high morbidity of the brucellosis in humans and the potential use of the microorganism as an agent of biologic warfare, protection of effective vaccines and specific diagnostic reagents become necessary to eradicate brucellosis. objective: in this study we aimed to investigate the cytokine responses and changes in peripheral blood lymphocyte subgroups of acute brucellosis...

background: pro-inflammatory and anti-inflammatory cytokines and polymorphisms of their genes have been described to be involved in the pathogenesis of recurrent miscarriage (rm). objective: to investigate the association between rm and five polymorphisms of cytokine genes, interleukin 10 (il-10), (-592 a/c, -819 c/t, -1082 a/g), il-6 (-174 c/g) and il-17 (-197 g/a) in iranian women. method: po...

objective(s): this study aimed to investigate the role and the possible mechanisms involved in the immunoregulation of experimental periodontitis by th17/treg. materials and methods: experimental periodontitis was established by silk thread ligation with porphyromonasgingivalis daubing in the bilateral maxillary second molar of male sprague-dawley (sd) rats. alveolar bones were scanned by micro...
