A study by researchers at the University of North Carolina at Chapel Hill suggests that training women to self-collect genital samples to test for human papillomavirus (HPV), the causative agent of cervical cancer, can increase the coverage rates of cervical cancer screening. Higher screening coverage helps increase rates of detection of cervical lesions and ultimately treatment of the disease. http://medicalxpress.com/news/2013-05-self-collection-samples-hpv-cervical-cancer.html Cancer Wed, 01 May 2013 15:24:56 EST news286640574 In a study using mice, researchers from the University of North Carolina at Chapel Hill found that a hormone, adrenomedullin, plays a crucial role in preventing the pregnancy complication preeclampsia. Surprisingly, this hormone protects women from preeclampsia when emitted by the fetus, not the mother, during the most critical times in pregnancy. http://medicalxpress.com/news/2013-05-baby-fetuses-emit-hormone-crucial.html Medical research Wed, 01 May 2013 12:00:01 EST news286624849 University of North Carolina researchers have discovered that disrupting a gene that acts as a regulatory switch to turn on other genes can keep blood vessels from forming and developing properly. http://medicalxpress.com/news/2013-04-uncovers-molecular-role-gene-linked.html Medical research Mon, 29 Apr 2013 12:41:09 EST news286458050 A monoclonal antibody targeting a protein known as SFPR2 has been shown by researchers at the University of North Carolina to inhibit tumor growth in pre-clinical models of breast cancer and angiosarcoma. http://medicalxpress.com/news/2013-04-monoclonal-antibody-inhibits-tumor-growth.html Cancer Fri, 19 Apr 2013 15:10:01 EST news285602419 In the wake of recent mass shootings such as the one in Newtown, Conn., physicians are increasingly being called on to pass judgment in the permitting process on whether their patient is physically and mentally competent to safely have and use a concealed weapon. http://medicalxpress.com/news/2013-04-doctors-involved-concealed-weapons.html Health Thu, 18 Apr 2013 09:59:02 EST news285497933 Researchers at the University of North Carolina have discovered that transcription factors regulating the levels of oxygen in the blood also play a role in the spread of the skin cancer melanoma. http://medicalxpress.com/news/2013-04-transcription-factors-blood-oxygen-linked.html Cancer Tue, 16 Apr 2013 11:04:50 EST news285329084 Researchers at the University of North Carolina at Chapel Hill School of Medicine have "rationally rewired" some of the cell's smallest components to create proteins that can be switched on or off by command. These "protein switches" can be used to interrogate the inner workings of each cell, helping scientists uncover the molecular mechanisms of human health and disease. http://medicalxpress.com/news/2013-04-protein-role-cancer-key-players.html Cancer Wed, 10 Apr 2013 12:43:39 EST news284816611 A study from the University of North Carolina School of Medicine offers new insights into how the nervous system processes hot and cold temperatures. The research led by neuroscientist Mark J. Zylka, PhD, associate professor of cell biology and physiology, found an interaction between the neural circuits that detect hot and cold stimuli: cold perception is enhanced when nerve circuitry for heat is inactivated. http://medicalxpress.com/news/2013-04-hot-cold-interact.html Neuroscience Mon, 08 Apr 2013 15:54:41 EST news284655275 Viruses have historically been classified into one of two types – those with an outer lipid-containing envelope and those without an envelope. For the first time, researchers at the University of North Carolina have discovered that hepatitis A virus, a common cause of enterically-transmitted hepatitis, takes on characteristics of both virus types depending on whether it is in a host or in the environment. http://medicalxpress.com/news/2013-04-hepatitis-virus-cloak-membranes-hijacked.html Diseases, Conditions, Syndromes Thu, 04 Apr 2013 11:25:25 EST news284293517 Millions of adults are exposed to traumatic events each year.

However, the virus has evolved to contain a gene that blocks this ability. When this gene is removed from the virus, the innate human immune system destroys HIV by mutating it to the point where it can no longer survive. http://medicalxpress.com/news/2013-03-innate-immune-hiv-viral-gene.html HIV & AIDS Thu, 28 Mar 2013 17:00:03 EST news283707538
