The role of endoplasmic reticulum stress in the pathophysiology of periodontal disease.

The endoplasmic reticulum (ER) is a principal organelle for folding, post-translational modifications and transport of secretory, luminal, and membrane proteins. ER stress is a condition induced by the accumulation of unfolded or misfolded proteins owing to a variety of physiological and pathological phenomena. To overcome the deleterious effects of ER stress, unfolded protein response (UPR) is initiated to translocate and remove the misfolded and accumulated proteins.

Immunological regulatory effect of flavonoid baicalin on innate immune toll-like receptors.

As an essential component of the innate immune system, Toll-like receptors (TLRs) are a family of well-recognized ligand-binding receptors found in various organisms and initiate host immune responses. Activation of TLRs signaling pathways lead to the induction of numerous genes that function in host defense. Baicalin is a natural compound from the dry raw root of Scutellaria baicalensis (S.

The role of autophagy in the pathogenesis of periodontal disease.

Periodontal disease is a chronic inflammatory disease leading to destruction of periodontal tissues. As a local inflammation, periodontopathic bacterium, pro-inflammatory mediators, and local immune response play pivotal role in the progress of periodontal disease. Besides, cigarette smoke has long been associated with periodontal disease and tooth loss.

Protective role of flavonoid baicalin from Scutellaria baicalensis in periodontal disease pathogenesis: A literature review.

Introduction: Periodontal disease is characterized by a chronic infection, leading to the irreversible destruction of tissues supporting the teeth. Bacteria, pro-inflammatory mediators and host immune response play important role in the progress of periodontal disease. Baicalin is a bioactive flavone extracted from the dry raw root of Scutellaria baicalensis, with pharmaceutical actions of anti-inflammation, anti-oxidants, anti-tumor, antivirus, and so on.

Dietary supplementation of soy germ phytoestrogens or estradiol improves spatial memory performance and increases gene expression of BDNF, TrkB receptor and synaptic factors in ovariectomized rats.

Background: Estrogen or phytoestrogens treatment has been suggested to improve cognitive function of the brain in postmenopausal women. However, there is lack of information on the mechanism of such treatment on the central nervous system. The present study aimed to determine the effects of estradiol and soy germ phytoestrogens on spatial memory performance in ovariectomized rats and to explore the underlying mechanisms affecting the central nervous system.

[Effect of fructus corni polysaccharides on damaged sexual function of male rats].

Objective: To observe the effects of Fructus Corni polysaccharides (FCP) on sexual function of hemicastrated rats.

Method: 70 male SD rats are randomly divided into 7 groups with their right testis extirpated except for normal control group. Normal control group and negative control group are given saline (ig) while positive control group are injected hypodermically testosterone propionate at dose of 2 mg x kg(-1) x d(-1).

Lycium barbarum polysaccharides induce apoptosis in human prostate cancer cells and inhibits prostate cancer growth in a xenograft mouse model of human prostate cancer.

Lycium barbarum polysaccharides (LBPs) are important functional constituents in red-colored fruits of L. barbarum (Guo Qi Zi, a well-known traditional Chinese medicinal plant commonly known as Goji berry or wolfberry). The influence of LBP on human prostate cancer cells was systematically investigated in vitro and in vivo.

Lycium barbarum polysaccharides: Protective effects against heat-induced damage of rat testes and H2O2-induced DNA damage in mouse testicular cells and beneficial effect on sexual behavior and reproductive function of hemicastrated rats.

Lycium barbarum, a famous Chinese medicinal herb, has a long history of use as a traditional remedy for male infertility. Polysaccharides are the most important functional constituent in L. barbarum fruits.
