Arbutin has antioxidative properties with potential benefits in many diseases. In this study, the cytoprotective and antioxidant effects of arbutin against t-BPH induced oxidative stress in Hep G2 cells were evaluated. HepG2 cells were cultured in 24-well plates (2.5×10 cells in 1 ml RPMI-1640 + 10% FBS+1% Pen. 5 Strep). Arbutin at different concentrations (0, 50, 100 and 150 μM) were added int...

We aimed to identify the hepatoprotective effects of Terminalia chebula water extract (TCW) and its corresponding pharmacological actions using C57/BL6 mice model of tert-butylhydroperoxide-(t-BHP-) induced acute liver injury. Mice were orally administered with TCW (0, 50, 100, or 200 mg/kg) or gallic acid (100 mg/kg) for 5 days before t-BHP (2.5 mM/kg) injection. Liver enzymes, histopathology,...

The ceramic fiber business of Shinnikka Thermal Ceramics Corporation began in March 1984 when its Sakai Works (then Nippon Steel Chemical Sakai Works) started production of ceramic fibers after several years of preparatory arrangements. The continuous reheating furnace having all-ceramic fiber lining, high thermal efficiency and low thermal inertia that was adopted for the plate mill (put into ...

We study the European river Danube and the South American river Negro daily water levels. We present a fit for the Negro daily water level period and standard deviation. Unexpectedly, we discover that the river Negro and Danube are mirror rivers in the sense that the daily water levels fluctuations histograms are close to the BHP and reversed BHP, respectively.

PURPOSE To identify the mechanisms by which oxidative stress with oxidizing agents alters the activity of ion channels in human retinal pigment epithelial (RPE) cells. METHODS The effects of oxidizing agents on ion currents were investigated in human RPE R-50 cells with the aid of the whole-cell, cell-attached, and inside-out configurations of the patch-clamp technique. RESULTS In the whole...

W artykule podjęto tematykę pracy na własny rachunek (samozatrudnienia) w kontekście obowiązujących Polsce gwarancji z zakresu bhp. Autorka analizuje aktualne regulacje Kodeksu tym zakresie perspektywy samozatrudnionych oraz wskazuje niedoskonałości przepisów. Formułuje także postulaty de lege ferenda, podejmując próbę zaproponowania modelowego ujęcia prawa do bhp dla zależnych. Dostrzega zasad...

BACKGROUND Staphylococcus epidermidis, a member of the human flora, is recognized as an opportunistic pathogen and cause of nosocomial infections. Staphylococcus epidermidis surface components are able to establish bacteria on the host surface, and cause infection. OBJECTIVES The frequency of icaA, IS256, aap, fbe and bhp in clinical isolates of S. epidermidis were investigated in this study....
