against STDs, they are not always used consistently and correctly and are a male-controlled method. The polyurethane female condom shows promise for STD protection as well as contraception, but its use still depends on male cooperation and acceptance. Because of women’s special biological susceptibility to sexually transmitted infection, their often disadvantaged position in gender relations an...

Experimental studies carried out for evaluating the anti-hyperlipidemic properties of rice bran components have given interesting but often contrasting results. Therefore, the current study was initiated to investigate the anti-hyperlipidemic activity of oryzanol (OZ), a commercially-important bioactive phytochemical, isolated from crude rice bran oil (cRBO). OZ was isolated by a two-step solve...

Matriptase, also known as MT-SP1, is a type II transmembrane serine protease strongly implicated in both the development and progression of a variety of epithelial cancers. Evidence comes from studies of its expression in human cancers and from mouse models of spontaneous cancer. Matriptase is considered to be a major activator of two key stimulators of invasive growth, namely hepatocyte growth...

The human oro-gastrointestinal (GI) tract is a complex system, consisting of oral cavity, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and anus, which all together with the accessory digestive organs constitute the digestive system. The function of the digestive system is to break down dietary constituents into small molecules and then absorb these for subsequent distr...

The development of ovarian cancer, unlike that of most human tumors, is rarely dependent upon the mutually exclusive loss of RB and p16 cell cycle proteins. RB+/p16+ ovarian cancer cell lines are, however, insensitive to the growth-suppressive effects of ectopically expressed p16 protein, which suggests that they harbor as yet unidentified defects that compromise cell cycle regulation in late G...
