Background: Chronic obstructive pulmonary disease (COPD) is a chronic airway inflammatory disease characterized by irreversible airflow obstruction. Pathogenic mechanisms underlying COPD remain largely unknown.
The effect of Lycium Barbarum L. (LB) on the free radical defending system during hypoxia was tested. Fifty six mice were divided into 3 groups. Experimental mice were fed with LB and the control mice were fed with distilled water by tube feeding for 16 days. Animals were put into each enclosed
BACKGROUND
Lycium barbarum polysaccharides (LBPs) are major ingredients of fructus lycii, which have multiple pharmacological activities, such as antioxidant, neuroprotective, and anti-inflammatory activities. This study attempted to reveal the potential of LBPs in hypoxia-injured H9c2 cells and the
Objective To investigate the expressions of silent mating type information regulation 2 homolog-1 (SIRT1), matrix metalloproteinase-9 (MMP-9) and hypoxia inducible factor 1α (HIF-1α) in hypoxic pulmonary vascular smooth muscle cells (PVSMCs) treated with Lycium barbarum polysaccharides (LBP).
It has been indicated that tumor necrosis factor receptor-associated factor-6 (TRAF6) will upregulate the expression of hypoxia-inducible factor-1α (HIF-1α) and promote tumor angiogenesis. TRAF6 proteins can be treated as drug target proteins for a differentiation therapy against cancers. As
The objective of this study was to investigate the protective effects of Lycium barbarum polysaccharides (LBP) on testicular spermatogenic function in streptozotocin (STZ)-induced diabetic rats. Compared to the control group, blood glucose levels were significantly increased and the insulin
Chronic intermittent hypoxia (CIH) is a hallmark of obstructive sleep apnea (OSA), which induces hippocampal injuries mediated by oxidative stress. This study aims to examine the neuroprotective mechanism of Lycium barbarum polysaccharides (LBP) against CIH-induced spatial memory deficits. Adult
BACKGROUND
The fruits of Hippophae rhamnoides L., Lycium barbarum L., Lycium ruthenicum Murr. and Nitraria tangutorum Bobr. are traditional medicinal food of Tibetans and used to alleviate fatigue caused by oxygen deficiency for thousands of years. The present study focused on exploiting natural
The accumulation of excessive reactive oxygen species can exacerbate any injury of retinal tissue because free radicals can trigger lipid peroxidation, protein damage and DNA fragmentation. Increased oxidative stress is associated with the common pathological process of many eye diseases, such as
Pregnancy complications are associated with abnormal cytotrophoblast differentiation and invasion. Hydrogen peroxide (H2O2) is an important mediator of oxidative ischemia/reperfusion stress in the placenta. Lycium barbarum polysaccharides (LBP) have been demonstrated to counteract oxidative free
