Structure of a Hantavirus Protein is a Promising Model for Drug Design
February 26th 2016Bank voles are small rodents that are not dangerous by themselves, but their excreta can contain one of the dangerous hantaviruses. While bank voles are unaffected by the infection, hantaviruses can cause potentially fatal diseases in humans for which no treatments exist. In central and northern Europe, infection is accompanied by fever, headache, or even renal failure. The strain that occurs in East Asia -- the Hantaan virus -- is even more dangerous: up to 5 percent of infected patients die of hemorrhagic fever, renal failure, or severe respiratory disorders.
HIV in Rhode Island: Newly Diagnosed Men Often Hooked Up Online
February 26th 2016More than 60 percent of Rhode Island men who have sex with men (MSM) diagnosed with HIV in 2013 reported meeting sexual partners online in the preceding year, according to a study published today in the journal Public Health Reports.
Post-Ebola Syndrome in Sierra Leone
February 25th 2016Researchers from the University of Liverpool's Institute of Translational Medicine have conducted a study of Ebola survivors to describe the medical problems they continue to have after recovering from the acute disease. The results have been published in the journal Emerging Infectious Diseases.
Analyzing Genetic Tree Sheds New Light on Disease Outbreaks
February 25th 2016Scientists have a new tool for unraveling the mysteries of how diseases such as HIV move through a population, thanks to insights into phylogenetics, the creation of an organism's genetic tree and evolutionary relationships.
Tackling Zika Using Bacteria as a Trojan Horse
February 25th 2016Bacteria in the gut of disease-bearing insects - including the mosquito which carries the Zika virus - can be used as a Trojan horse to help control the insects' population, new research at Swansea University has shown. The results showed declines in fertility of up to 100 percent and an increase of 60 percent in the mortality rate of larvae, among the insects studied.
Scientists Develop Infection-Fighting Bandages for Serious Burns
February 25th 2016Serious burn victims are immunocompromised and may be missing skin on parts of their body, and this makes them highly vulnerable to bacteria. Thanks to progress in intensive care, they are decreasingly likely to die from burn trauma. Death is more commonly the result of infections that can occur several months after being hospitalized. The bandages used to treat burns actually represent a real breeding ground for microbes.
Simpler Technique Yields Antibodies to a Range of Infectious Agents
February 24th 2016Researchers hope to develop vaccines, therapeutics and new diagnostic tests for a broad range of diseases. To accomplish this, they will need to gain a much better understanding of a critical class of biological components. Known as surface membrane proteins, these vital ingredients in the disease process form a structurally and functionally diverse assemblage of enormous complexity.
Zika Response Accelerates as WHO Director-General Visits Brazil
February 24th 2016As the World Health Organization (WHO) continues its work to guide the international response to Zika, the director-general, Margaret Chan, MD, has arrived in the northeast part of the country to visit the area most affected by neurological disorders suspected of being linked to the virus, including microcephaly in babies.
