Novel screening approach for stem cell selective inhibitors and their possible translational therapeutic potential for endometriosis.

Endometriosis is an estrogen-dependent benign disease characterized by growth of the endometrial tissue outside the uterine wall. Several reports suggest the possibility of the pathogenesis and recurrence of endometriosis being related to functions of stem/progenitor cells of the endometrium. The drawback of the widely used method of using Hoechst 33342, a fluorescent dye, to collect stem cell-like populations, is the requirement of an ultraviolet (UV) excitation source not commonly provided on standard flow cytometers.

Dynamic amplification of light signals in photorefractive ferroelectric liquid crystalline mixtures.

The photorefractive effect in photoconductive ferroelectric liquid crystals that contain photoconductive chiral compounds was investigated. Terthiophene compounds with chiral structures were chosen as the photoconductive chiral compounds, and they were mixed with an achiral smectic C liquid crystal. The mixtures exhibit the ferroelectric chiral smectic C phase.

Eicosapentaenoic acid attenuates progression of hepatic fibrosis with inhibition of reactive oxygen species production in rats fed methionine- and choline-deficient diet.

Background And Aims: Nonalcoholic steatohepatitis (NASH) is associated with fat accumulation in the liver, and develops to cirrhosis with the progression of hepatic fibrosis. Eicosapentaenoic acid (EPA) is used to treat hyperlipidemia, and suppresses hepatic fat accumulation. As the effect of EPA on NASH remains unclear, we assessed the therapeutic effect of EPA and its mechanisms in an animal model of NASH.

Highly purified eicosapentaenoic acid ethyl ester prevents development of steatosis and hepatic fibrosis in rats.

Background And Aims: Pathogenesis of nonalcoholic steatohepatitis (NASH) is considered to be involved in fat accumulation, oxidative stress, inflammation, and fibrosis in liver, but no drug therapy has been established as yet. Eicosapentaenoic acid (EPA) is an agent used clinically to treat hypertriglyceridemia, and has been reported to suppress reactive oxygen species and inflammation. Here, we aimed to assess the effect of EPA on progression of hepatic fibrosis in an animal model of NASH.

Suppression of hepatic fat accumulation by highly purified eicosapentaenoic acid prevents the progression of d-galactosamine-induced hepatitis in mice fed with a high-fat/high-sucrose diet.

The pathogenesis of non-alcoholic fatty liver disease (NAFLD) remains largely unknown. Here, we assessed the importance of hepatic fat accumulation on the progression of hepatitis. BALB/cA mice were fed with a standard diet (STD) or a high-fat and high-sucrose diet (HFHSD) for 14 days followed by intraperitoneal injection of d-galactosamine (DGalN) or vehicle.

Highly purified eicosapentaenoic acid prevents the progression of hepatic steatosis by repressing monounsaturated fatty acid synthesis in high-fat/high-sucrose diet-fed mice.

Eicosapentaenoic acid (EPA) is a member of the family of n-3 polyunsaturated fatty acids (PUFAs) that are clinically used to treat hypertriglyceridemia. The triglyceride (TG) lowering effect is likely due to an alteration in lipid metabolism in the liver, but details have not been fully elucidated. To assess the effects of EPA on hepatic TG metabolism, mice were fed a high-fat and high-sucrose diet (HFHSD) for 2 weeks and were given highly purified EPA ethyl ester (EPA-E) daily by gavage.
