Oxidative stress can damage lipids, proteins and DNA. The effect of hydrolysed, purified defatted egg yolk protein by-product (fraction EYGF-23) on oxidative stress in Caco-2 colon cancer epithelial cells was investigated for the first time. Caco-2 cells exposed to toxic 3 mM tert-butyl hydroperoxide (t-BHP) for 2 hours were protected when pretreated with 1.0 mg/ml EYGF-23 for 24 hours. The pep...

This study investigated the antioxidative effect of rooibos herbal tea and a rooibos-derived commercial supplement on tert-butyl hydroperoxide- (t-BHP-) induced oxidative stress in the liver. Forty male Wistar rats consumed fermented rooibos, unfermented rooibos, a rooibos-derived commercial supplement, or water for 10 weeks, while oxidative stress was induced during the last 2 weeks via intrap...

Postoperative hip alignment was studied on radiographs in cases of total hip arthroplasty (THA) and of Bipolar Head Prosthesis(BHP), both with MX-1. Postoperative anteroposterior-view radiographs of hip joints of patients with a normal hip joint on the unoperated side and without pelvic tilt were used. Thirty-nine THA patients (femoral neck fracture), 26 THA patients (osteonecrosis of the femor...

Sulfuretin is one of the major flavonoid components in Rhus verniciflua Stokes (Anacardiaceae) isolates. In this study, we investigated the protective effects of sulfuretin against tert-butyl hydroperoxide (t-BHP)-induced oxidative injury. The results indicated that the addition of sulfuretin before t-BHP treatment significantly inhibited cytotoxicity and reactive oxygen species (ROS) productio...

Objective: to examine the possibilities for implementing ISO 45003:2021 guidelines managing psychosocial risk and promoting well-being at work into an occupational health safety (OH&S) management system (compliant with requirements of 45001:2018). Research Design & Methods: Analysis standards literature on health. 45001:2018 were main subjects research. Findings: The guidelines, which c...

Oxidative stress causes endothelial death while underlying mechanisms remain elusive. Herein, the pro-death effect of tert-butyl hydroperoxide (t-BHP) was investigated with low concentration (50μM) of t-BHP (t-BHPL) and high concentration (500μM) of t-BHP (t-BHPH). Both t-BHPL and t-BHPH induced endothelial cell death was determined. T-BHPL induced caspase-dependent apoptosis and reactive oxyge...

Reliable and durable asphalt surfacing systems still remain to be desired for the long-spanned orthotropic steel bridges as the nationally and internationally reports on distresses in deck pavement. Based on ten-year research works, this paper has presented a brief review and discussion of the Chinese practices and experiences of deck pavement on long-spanned steel bridges, including issues of ...

This paper investigates the effect of moisture content on interface shear strength between offshore clay and steel plate. Although, sensitive and high plasticity offshore clay deposits are widely distributed in Malaysia and many other countries in the world, and steel is a vital construction material for many structures, research works on interaction between offshore clay and steel surface are ...

Curcuminoids are well known for their capabilities to combat risk factors that are associated with ageing and cellular senescence. Recent reports have demonstrated that curcuminoids can extend the lifespan of model organisms. However, the underlying mechanisms by which these polyphenic compounds exert these beneficial effects remain unknown. In this study, t-BHP-induced premature senescence mod...
