A study done by researchers from Peking University shows beneficial effects of tea. The researchers studied the association between tea consumption and ischemic heart disease event among more than 487,000 Chinese adults, aged between 30 to 79 years. Findings show daily consumption of tea is associated with the lower risks to the ischemic heart disease. But the amount of risk may not decrease with the increase in the consumption of tea. Researchers observed fewer incidents of major coronary events among tea consumers and they say tea is a healthy drink. The leader of the study is Prof LimingLi MD, Peking University Beijing and the study findings were published in the Heart.
A research study shows the release of nitric oxide (NO) into the bloodstream, which is a powerful blood pressure (BP) lowering agent when sunlight strikes on the skin. UVB light dilates (make wider) blood vessels and capillaries (fine branches of blood vessels) in the skin. Oral supplements may not benefit an individual in reducing blood pressure (BP) because they may not increase nitric oxide in the bloodstream. Researchers from Sweden says risk amount with the avoidance of sun exposure is similar to the risk associated with smoking. Previous studies show high blood pressure (BP) is a risk factor for cardiovascular diseases, stroke and heart diseases.
Ultraviolet (UV) sun rays exposure kills germs and infections in our blood. These rays were used to treat TB during late 19th and early 20th century. Other benefits of sun exposure to the skin are better bone health, reducing skin disorders, quality of sleep, an enhancement to the immune system, improved brain function and reduction in risk of some cancers. The study findings were published in the journal Cancer Research Frontiers.
A study done by researchers from Stanford University Medical Center and Institute of Medical Science, University of Tokyo shows curing diabetes with new beta cells grown in another animal. The researchers performed current procedure between rat and mouse by transplanting stem cells of the mouse with diabetes into rat pancreas to enable transplanted cells to produce insulin. Later they transplanted insulin-producing beta cells back into the mouse. The newly transplanted insulin beta cells cured diabetes in the mouse and normalized the blood sugar levels for a year. Immunosuppression drugs (to prevent the rat immune system to reject foreign transplanted cells) were not required as cells of a rat were a genetic match to the mouse. The recipient animal needed immunosuppressive drugs for five days.
The researchers say this method is effective in treating diabetes as there is a shortage of organ donors to meet the demand. The success of this procedure shows the development of other human organs from large animals such as sheep and pigs in future. Compared to other previous studies done on the same subject, this study differs in the creation of a number of insulin-producing cells as the current study produced more insulin-producing cells. Now the researchers are conducting experiments for transplantation of other human organs such as liver, lungs and kidneys. Senior Author of the study is Dr. Hiromitsu Nakauchi, Professor in genetics and the study findings were published in Nature.
