Cellular prion protein (PrPc) is a glycosylphosphatidylinositol (GPI) -anchored membrane protein that is highly conserved in mammalian species. PrPc has the characteristics of adhesive molecules and is thought to play a role in cell adhesion and membrane signaling. Here we investigated the possible role of PrPc in the process of invasiveness and metastasis(More)
Angiomatous meningioma (AM) is a rare histological variant of meningioma. Twenty seven patients (14 male and 13 female) with angiomatous meningioma were treated in our institution. Their clinical presentation, neuroimaging studies, treatment and follow-up were investigated. The age of patients ranged from 24 to 72 years with a mean of 51.8 years. The(More)
MOTIVATION Mutagenicity is among the toxicological end points that pose the highest concern. The accelerated pace of drug discovery has heightened the need for efficient prediction methods. Currently, most available tools fall short of the desired degree of accuracy, and can only provide a binary classification. It is of significance to develop a(More)
Human papillomaviruses (HPV) cause cutaneous and genital warts. A subset of HPV types is associated with a high-risk for progression to malignancy. The E6 protein from the high-risk HPV types represents an attractive target for intervention because of its roles in viral propagation and cellular transformation. E6 functions in part by interaction with human(More)
BACKGROUND Despite advances in bowel preparation methods, the quality of bowel preparation in some patients undergoing colonoscopy remains unsatisfactory. The effect of telephone re-education (TRE) on the day before colonoscopy on the quality of bowel preparation and other outcome measures had not been studied. METHODS A prospective colonoscopist-blinded(More)
Sepsis is a systemic inflammatory response syndrome and is mainly caused by lipopolysaccharides (LPS) - a component of the cell walls of gram-negative bacteria, via toll-like receptor 4-mitogen-activated protein kinases/nuclear factor-kappa B-dependent proinflammatory signaling pathway. Here, we synthesized 26 asymmetric monocarbonyl analogs of curcumin and(More)
Effective novel therapeutics is urgently needed due to increasing incidence of malignant cancer and drug multi-resistance. Natural products and their derivatives have historically been a source of pharmaceutical leads and therapeutic drugs. Microtubule-targeting compounds are among the most promising candidates in the combat against cancer. In particular,(More)
Gastric cancer (GC) is one of the leading causes of cancer mortality in the world. In addressing the need of treatments for relapsed disease, we report the identification of an existing U.S. Food and Drug Administration-approved small-molecule drug to repurpose for GC treatment. Auranofin (AF), clinically used to treat rheumatic arthritis, but it exhibited(More)
Reported data indicate that cholesterol loading in the liver can cause hepatic injury. To explore the possible mechanisms of cell damage resulting from cholesterol overloading in hepatocytes, cell apoptosis, the unfolded protein response (UPR) and the correlation between them were assessed in the cholesterol-overloaded normal human hepatic cell line L02.(More)
