OBJECTIVE To investigate the role of interleukin-1beta (IL-1beta) in regulating GnRH mRNA expression in cultured human endometrial stromal cells using a modified semiquantitative competitive reverse transcription and polymerase chain reaction (PCR). DESIGN A controlled study. SETTING Clinical and academic research setting in a university medical center. PATIENT(S) Women undergoing hystere...

Acute stressor exposure can facilitate innate immunity and suppress acquired immunity. The present study further characterized the potentiating effect of stress on innate immunity, interleukin-1beta (IL-1beta), and demonstrated that stress-induced potentiation of innate immunity may contribute to the stress-induced suppression of acquired immunity. The long-term effect of stress on IL-1beta was...

A persistent Staphylococcus epidermidis infection in mice around a subcutaneous polyvinylpyrrolidone-grafted silicon elastomer catheter (SEpvp) but not around a conventional silicon elastomer catheter was observed. With SEpvp pericatheter tissue, protracted and exaggerated interleukin-1beta (IL-1beta) production was found. Apparently, sustained levels of IL-1beta are associated with enhanced su...

Interleukin-1beta (IL-1beta) is a potent pro-inflammatory cytokine that is primarily produced by microglia in the brain. IL-1beta inhibits N-methyl-d-aspartate (NMDA)-induced outward currents (I(NMDA-OUT)) through IL-1 type I receptor (IL-1RI) in hippocampal CA1 neurons (Zhang, R., Yamada, J., Hayashi, Y., Wu, Z, Koyama, S., Nakanishi, H., 2008. Inhibition of NMDA-induced outward currents by in...

In the present study, fish were exposed to sub-lethal doses of CuONPs (68.92 ± 3.49 nm) (10 mg/L, 20 and 50 mg/L) for a long exposure period (25 days). Compared control group (0.0 mg/L CuONPs), significant dose-dependent elevation in blood urea creatinine values, serum alanine transaminase, aspartate alkaline phosphatase enzyme activities evident CuONPs-exposed groups (p < 0.05). Fish signif...
