The death toll from the outbreak of Rift Valley fever in Kenya’s Wajir District has risen to 52 after four people reportedly died. According to reports, the Rift Valley fever killed three other people in neighbouring Isiolo District.
Much like flipping a light switch, the hepatitis C virus turns on human immune defenses upon entering the body but also turns off those defenses by manipulating interaction of key cellular proteins, UT Southwestern Medical Center researchers have found.
By incorporating the idea of a feedback resistor into the HIV Tat transcriptional circuit, and by using real-time imaging experiments, this study provides insight into how HIV enters periods of latency.
The Joint United Nations Programme on HIV/AIDS (UNAIDS) expresses deep concern over the verdict delivered yesterday by a Libyan court sentencing six health care professionals to death for the alleged intentional transmission of HIV, and strongly urges that the verdict be reviewed by the higher courts.
New studies on nutrition and HIV from researchers at Tufts University in Boston find that a high percentage of people with HIV have the same two characteristics of metabolic syndrome, and that people with HIV on HAART may be at risk for zinc deficiency.
IRD immuno-virologists and their research partners have determined the mechanisms involved in the occurrence of the vascular leakage triggered by the Dengue virus. Metalloproteinases are responsible for the passage of plasma across the blood-vessel walls. These original results, validated first by in vitro tests then in vivo on a mouse model, open up the first line of attack for treatment against hemorrhagic Dengue and new perspectives for others hemorrhagic fevers, such as Ebola.
The Food and Drug Administration (FDA) is alerting health care professionals and patients treated with Rituxan (rituximab) to reports of an emerging risk of a serious side effect in patients receiving or who have used Rituxan.
Following kidney transplantation, some recipients may face a three-fold increased risk of certain cancer types, according to a study in the Dec. 20 issue of JAMA.
Researchers at the University of Maryland School of Medicine in Baltimore will begin a clinical trial in January to test the first cell culture-based pandemic influenza vaccine to see if it will provide immunity faster and more reliably than a vaccine produced in eggs. The new study is also the first test in the United States of a whole virus vaccine for avian influenza, which could produce a stronger response by the immune system.
HIV-infected patients undergoing surgical procedures may be more likely to develop pneumonia after surgery and to die within 12 months than those without HIV, according to a report in the December issue of Archives of Surgery, one of the JAMA/Archives journals. In addition, HIV patients with a preoperative viral load (number of copies of the virus in the blood) greater than 30,000 per milliliter appear to have increased risk of surgical complications.
