objective(s): gardenia jasminoides ellis (gj, cape jasmine fruit, zhi zi) has been traditionally used for the treatment of infectious hepatitis, aphthous ulcer, and trauma; however, the direct evidence is lacking. materials and methods:we investigated the effect of the gj extract(gj) and gallic acid (ga) on lipopolysaccharide (lps) induced inflammation of bv-2 microglial cells and acute liver i...

It has long been recognized that an increase of reactive oxygen species (ROS) can modify the cell-signaling proteins and have functional consequences, which successively mediate pathological processes such as atherosclerosis, diabetes, unchecked growth, neurodegeneration, inflammation, and aging. While numerous articles have demonstrated the impacts of ROS on various signaling pathways and clar...

The endogenous reactive oxygen species ("ROS") formation is associated with many pathologic states such as inflammatory diseases, neurodegenerative diseases, brain and heart ischemic injuries, cancer, and aging. The purpose of this study was to investigate the endogenous sources for "ROS" formation in intact isolated rat hepatocytes, in particular, peroxisomal oxidases, monoamine oxidase, xanth...

We present rosbridge, a middleware abstraction layer which provides robotics technology with a standard, minimalist applications development framework accessible to applications programmers who are not themselves roboticists. Rosbridge provides a simple, socket-based programmatic access to robot interfaces and algorithms provided (for now) by ROS, the open-source “Robot Operating System”, the c...

Spermatozoa generate reactive oxygen species (ROS) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (AR) and oocyte fusion. In addition damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. Besides human seminal plasma and sperm posses...

in this study, we investigate the potential of moricandia arvensis methanol leaf extract (meohl) on calpain activity, melanin biosynthesis and dna mutagenicity. cytotoxic effect and measurement of reactive oxygen species (ros) induced by lucigenin in colorectal cells (be) were also determined. in addition the chemical analysis of the extract was also studied and the chemical profile illustrates...
