2014 is an exciting field of medical research a year, research teams around the world for in-depth analysis of human disease prevention and make unremitting efforts with the road. Some studies focus on ways to prevent aging or senescence, others are looking for ways to promote health.
1. Geographical origin of the United States and several European countries AIDS researchers formed a joint research team of multi-regional, to piece together the AIDS when, where, and in what way the first infected humans. Through data analysis, the research team locked foci –Kinshasa, since the twenties so far is the capital of the Democratic Republic of Congo. The team’s findings, published in the journal Science. Just like people suspected, the first case of human infection from chimpanzees. The team’s research illustrates since the 1960s, social change and transportation contributed to the pandemic of AIDS.
2. Caesarean section or can cause epigenetic changes in a Swedish Karolinska Institutet researchers completed the study, there is evidence that can be produced by caesarean baby’s stem cells lead to the occurrence of certain change. The team found that these changes can increase the risk of autoimmune diseases, such as asthma, I diabetes, celiac disease and the like. The results have been published in the American Journal of Obstetrics and Gynecology, the same time pointed out that we do not know this epigenetic change is permanent or temporary.
3. “Trigger” brain researcher MedUni in Vienna Research Center Karolinska Institute in Sweden and colleagues of the brain during stress formed a joint research team. The team found that an important factor associated with stress: protein hormone secretagogues is the brain to release stress hormones – corticotropin releasing hormone (CRH) when a “trigger.” The team’s findings have been published in the EMBO Journal. Previous studies showed that, CRH is a signal is sent to the pituitary gland and other organs in the process of a ring.
4. A group of life science researchers to cancer of the pancreas, the first step in the Mayo Clinic confirmed the cause of the initial process of pancreatic cancer, the results may provide a method of treatment of cancer prevention at the source. The research results have been published in the journal Cancer Discovery. The team found that the initial process occurs at the molecular level of damage, some of which evolved into the damaged tumor growth.
