Retinal pigment epithelial (RPE) is an oxidation-resistant cell. But if it is subjected to various harmful stimuli for a prolonged period, an excessive amount of oxyradical will be generated to cause retinal dysfunction. We investigated and elucidated the protective mechanism of proanthocyanidins (SBP) against oxidative damage in RPE.

Sea buckthorn proanthocyanidins (SBPs) have good free radical scavenging ability. We established a senescence model by injecting 500 mg/kg D-galactose into the dorsal necks of mice, and then different doses of SBP (25, 50, and 100 mg/kg) were gavaged to explore the effects of SBP on the skin tissues of senescent mice and elucidate the related mechanism of action.

Excessive accumulation of reactive oxygen species (ROS) in cells induced by hydrogen peroxide (HO) triggers a decrease in collagen synthesis and an increase in collagen degradation, which are biomarkers of skin aging. We evaluated the potential protective mechanism of proanthocyanidins (SBP) against the oxidative stress-induced skin aging process from multiple aspects.

In this paper, sea buckthorn high methoxyl pectin (SBHMP) was obtained, with a yield of 8% and a light-colored. The SBHMP was a high methoxyl with a degree of esterification of 57.

Studies have shown that SBP have significant protective effects on macrophages against oxidative stress induced by hydrogen peroxide (HO). However, the mechanism remains uncertain.

Procyanidins from sea-buckthorn is a powerful antioxidant, although its protective effect on the cardiovascular system is not yet clearly understand. In this study, oxidative damaged HUVECs induced by palmitate acid (PA) were used as a model and the regulatory effect of procyanidins from sea-buckthorn (SBP) on HUVECs were investigated.

The IDF was treated with ball milling and cellulase treatment to obtain co-modified insoluble dietary fiber (CIDF). The physicochemical and functional properties of IDF, milled insoluble dietary fiber (MIDF), and CIDF were studied.

It continues by examining how local governments have reinforced and compounded the failures in the federal environmental regulatory framework, particularly through local land use decisions. Although states play an important role in environmental policymaking, we propose that local governments are uniquely positioned to utilize a health justice approach to address environmental health inequities.

Methods: We queried NCER's publically available online archive of funding opportunities from fiscal years 1997 to 2013. From an initial list of 211 RFAs that met our inclusion criteria, 33 discussed or incorporated elements of community engagement.

Equity is a core value of Health Impact Assessment (HIA). Many compelling moral, economic, and health arguments exist for prioritizing and incorporating equity considerations in HIA practice. Decision-makers, stakeholders, and HIA practitioners see the value of HIAs in uncovering the impacts of policy and planning decisions on various population subgroups, developing and prioritizing specific actions that promote or protect health equity, and using the process to empower marginalized communities.
