Our present studies on the cardiac function of KLF6 show a new mechanism whereby cardiomyocytes regulate cardiac fibrosis through transcriptional control of the extracellular matrix factor, TSP4, which, in turn, modulates activation of cardiac fibroblasts.

Based on the study results, breast cancer patients experienced living with uncertainty and maintaining hope. Thus the study's findings can be useful in directing a comprehensive nursing care plan to improve QOL of breast cancer patients.

Background/Aims: The present study was carried out to evaluate the nutritional quality of adlay (AD), buckwheat (BW) and waxy barley (WB), with particular respect to their fiber components. Plasma lipid parameters, gut transit time and thickness of the aortic wall in rats fed with different grains were evaluated and compared with rats fed on white rice (WR). Methods: The rats were then raised for 4 weeks on an obesogenic diet based on the American Institute of Nutrition-93 (AIN-93 G) diets containing 1% cholesterol and 20% dietary lipids. 40 male rats were divided into 4 groups and raised for 4 weeks with a diet containing one of the following grains: WR, AD, BW, or WB. Results: Gut transit time was shortened depending on the grain, with the WB group having the shortest time, followed by the BW group and the AD group, and then the WR group. Plasma lipid profiles differed significantly according to grain combination, and the levels of triglycerides in the AD, BW and WB groups were significantly lower than that in the WR group. The BW and WB groups showed lower levels of total cholesterol and LDL-C, and higher HDL-C than the WR group, although the group fed on AD did not show such results owing to the high content of lipids and calories. Accordingly, the reduction in gut transit time resulted in decreasing levels of triglycerides, total cholesterol and LDL-C. Rats fed on WB and BW showed significantly larger aortic lumen than those fed with AD and WR. Also the wall thickness of the WB group was significantly thinner than that of the WR group. Conclusion: Consumption of BW- and WB-containing diets significantly improved several cardiovascular risk factors induced by obesity in experimental rats.

In the present study, we examined whether four grains including adlay (AD), buckwheat (BW), glutinous barley (GB), and white rice (WR) affect the duration of food residence in the gastrointestinal tract and hepatic enzyme activities in rats fed different combinations of the grains. The rats were raised for 4 weeks on a high fat diet based on the American Institute of Nutrition-93 (AIN-93G) diets containing 1% cholesterol and 20% dietary lipids. Forty male rats were divided into four groups and raised for 4 weeks with a diet containing one of the grains. Corresponding to the dietary fiber contents of the experimental grains, gut transit time was shortest in the rats fed GB and increased in the order of BW, AD, and WR. In addition, the accumulated shortest transit time occurred in the GB group. Gut transit time affected weight gain and major organ weight, as it was closely related to the absorption of nutrients. The level of thiobarbituric acid reactive substance (TBARS) in liver was higher in rats fed WR, AD, BW, and GB, indicating that the other grains decreased oxidative stress in vivo more than WR. Glutathione, glutathione peroxidase, and glutathione S-transferase levels in the AD, BW, and GB groups were significantly higher than those in the WR group. In conclusion, reduced colonic transit time has been implicated in reducing the incidence of colon cancer, as evidenced by populations consuming diets rich in fiber. Whole grains such as AD, BW, and GB may contribute to a significant supply of antioxidants to prevent oxidative stress if they are consumed in large amounts.
