Cure diabetes no longer have an injection it!

For patients with type 1 diabetes, their immune system attacks the pancreas, resulting in the loss of the patient the ability to regulate blood sugar. These patients must often pay close attention to their blood sugar levels, sometimes a day needs to be measured several times, by injection of insulin to control blood sugar in a healthy range. But it is difficult to achieve accurate blood glucose control, diabetes patients need to face the problem of long-term treatment.

Many scientists believe that the replacement of pancreatic islet cells are damaged the patient is a better treatment with healthy islet cells, healthy islet cells can be properly regulate blood sugar and insulin release. This method has been used for some patients, but the main problems is that the patient's immune system will continue to attack the transplanted cells, so patients need long-term use of immunosuppressive drugs.

Recently, researchers from Children's Hospital Boston, USA MIT and other research units propose a new method for islet cell transplantation. They designed a new material capable of islet cell transplantation prior to the cells wrapped up, the researchers conducted experiments on mice, and the results show that these encapsulated human cells to treat diabetes, and the effect of up to six months at the same time does not cause the body to produce an immune response.

The authors, Professor Daniel Anderson says: "Although this research more research is needed to verify, but we believe that this method will be able to protect or type 1 diabetes patients with transplanted islet cells from the immune system attack, but can also the case without the help of medication the patient better control of blood sugar.

Butylone

The 'legal highs' readily available, products containing psychoactive substances such as cathinone, piperazines and synthetic cannabinoids, are consumed by young people in Poland and in the world as alternatives to conventional drugs such as amphetamines or marijuana . Most of these hazardous substances are still legal and they are at risk of severe poisoning or even connected to death, and offer new challenges in the practice of clinical and forensic toxicology. Investigations in the field of "synthetic drugs" may also be the case of a suicide of a man of 21 years who represented received a fixed dose of a preparation called "Amphi-bi-a", which contains BK- MBDB, chemically 2-methylamino-1 - (3,4-methylenedioxyphenyl) butane-1-one, which belongs to the category as a synthetic cathinone empathogen euphoric and psychoactive stimulant that is chemically similar to MDMA. It is one of the most common components of 'legal highs' studied in Poland and other countries. The documentation of the case includes a clinical assessment performed during its nearly 4 hours of patient health hospitalization before death, autopsy and histological supported by the results of toxicological examinations BK-MBDB at extremely high concentrations (to 20 mg / l found in the blood and 33 mg / kg in the liver); therefore transmits these references to knowledge in the field of "synthetic drugs". Inventions by designers of new foreign substance that are in high demand, especially for dynamic Internet marketing has narcobusiness drums must be compensated by a national strategy that develops medical, legal and educational in the modern world civilized, to prevent the spread of the phenomenon.

History of domestication meow star people

Meow star who now has such a high position is not accidental. A recent study showed that 5,000 years ago, Chinese farmers began to domesticate called "ocelot" wild cats. If this is true, it means accepting more than once domesticated cat (5000 years ago in China, the Middle East and earlier time). Meanwhile, the study also shows that the rise of agriculture makes the domestic cat appears inevitable.

 "This is a very interesting study," the ancient zoologists from Washington University in St. Louis Fiona Marshall said. If this is true, it means that a variety of other animals, including donkeys with sheep, including, in the absence of humans that had also once been too domesticated. "This has important implications for our understanding of the domestication process."

Marshall did not participate in the work, but a few years ago she helped analyze the excavation from central China village guard Stephen obtained eight with cat bones, according to research dating back more than 5300 years. According to test results of nitrogen and oxygen, they speculated that the smaller cats to grain for food. This evidence supports a long time about how the night cat domestication hypothesis: Night Cat rushed into the barn to capture rats and mice, but people are living trapped for capturing mice. According to the fossil imprint, they think these cats had been raising for a long time local human.

However, there is a big problem that the cat wildcat protect the village spring and the Near East if there is kinship? Now our family cat ancestors 10,000 years ago in what is the Middle East domesticated cats, or whether the smaller Central Asian wildcat or leopard cats?

This study gives a statement. Director from the French National Academy of Sciences of Jean-Denis Vigne et cat nursing Bone Springs Village and two other Chinese Cat Bone ancient farming areas were further probing, focusing mandible area. The results showed that the bones belong to all cats leopard cat, not the Near East species. Related results were published in "PLoS ONE" magazine latest issue.
