A Diffusion-Based Approach to Geminate Recombination of Heme Proteins with Small Ligands [PDF]
A model of postphotodissociative monomolecular (geminate) recombination of heme proteins with small ligands (NO, O2 or CO) is represented. The non-exponential decay with time for the probability to find a heme in unbound state is interpreted in terms of diffusion-like migration of ligabs physics/0212040 and between protein cavities.

The Dirichlet problem for a class of prescribed curvature equations [PDF]
In this paper, we consider the Dirichlet problem for a class of prescribed curvature equations. Both degenerate and non-degenerate cases are considered. The existence of the $C^{1,1}$ regular graphic hypersurfaces with prescribing a class of curvatures and constant boundary is proved for the degenerate case.

Heme oxygenase inhibition in cancers: possible tools and targets
Heme oxygenase-1 (HO-1, encoded by HMOX1) through degradation of pro-oxidant heme into carbon monoxide (CO), ferrous ions (Fe2+) and biliverdin, exhibits cytoprotective, anti-apoptotic and anti-inflammatory properties. All of these potentially beneficial

The hydro‐ethanolic extract of P. granatum peel was standardized. ;The extract increased superoxide dismutase activity and thiol content, while reduced function of AchE and peroxidation of lipid in the scopolamine‐injured rat’s brain. ;P. granatum may attenuate scopolamine injury through targeting nuclear factor‐E2‐related factor 2 pathway ; Abstract ...

This study indicated, for the first time, that (±) linalool and its enantiomer, (R)‐(‐) linalool protected PC12 cells against injury induced by oxygen and glucose deprivation/reoxygenation (OGD/R) via the mitigation of oxidative stress and the downregulation of Bax/Bcl‐2, caspase‐3 and caspase‐9, resulting in decreased apoptotic cell death.

An excess of reactive oxygen species (ROS) can cause cell damage, and an accumulation of damage leads to cellular dysfunction resulting in a variety of diseases including abnormal aging, cancer, diabetes, and inflammation. In this study, feruloyl oligosaccharides (FOs) were obtained by solid‐state fermentation using wheat bran, and antioxidant activity

Danshensu (Dan) attenuates lipopolysaccharide‐induced hepatic stellate cells activation via decreasing expression of collagen І, connective tissue growth factor, glutathione peroxidase 4, cystine/glutamate antiporter xCT, and lipocalin‐2. However, Dan increases lipid reactive oxygen species accumulation.
