Study confirms innate ability of ticks to adapt to changing climatic conditions

Carnivores in the Iberian Peninsula, such as the Iberian lynx, are under an increasingly serious threat: ticks that can adapt to changing climatic conditions and that can even survive in extremely arid environments. A study headed by Spanish researchers confirms the innate ability of ticks to adapt according to climate.

Infection with dengue virus turns on feeding-related genes in mosquitoes

Researchers at the Johns Hopkins Bloomberg School of Public Health have, for the first time, shown that infection with dengue virus turns on mosquito genes that makes them hungrier and better feeders, and therefore possibly more likely to spread the disease to humans.

Researchers, experts debate publication of H5N1 research amid updated studies

"As researchers from both sides of the debate over two controversial H5N1 studies weighed in Tuesday on full publication versus a more cautionary approach, two U.S. journals" -- the Journal of Infectious Diseases (JID) and its sister publication, Clinical Infectious Diseases -- "said they are developing policies to address any future such instances," CIDRAP News writes.

Women with HIV superinfection have more potent antibody responses

Women who have been infected by two different strains of HIV from two different sexual partners - a condition known as HIV superinfection - have more potent antibody responses that block the replication of the virus compared to women who've only been infected once. These findings, by researchers at Fred Hutchinson Cancer Research Center in Seattle, are published online March 29 in PLoS Pathogens.

HPV-related head and neck cancer on the rise among middle-aged white men

Research led by Lauren Cole, a public health graduate student, and Dr. Edward Peters, Associate Professor of Public Health and Director of the Epidemiology Program at LSU Health Sciences Center New Orleans, reports that the incidence of head and neck cancer has risen at sites associated with Human Papilloma Virus (HPV) infection, with the greatest increase among middle-aged white men.

Avian and swine flu viruses hijack genetic regulators during human infection

Researchers at the University of British Columbia have identified a number of tiny but powerful "genetic regulators" that are hijacked by avian and swine flu viruses during human infection.

Ethiopia's workplace HIV/AIDS policy aims to help employers, employees nationwide

Ethiopia's new HIV/AIDS workplace policy, instituted in January by the government in cooperation with the country's main employees' and employers' associations, "is expected to protect job seekers from mandatory HIV tests, while facilitating voluntary counseling and testing and defending the right of employees living with HIV to medical leave or job re-allocation," PlusNews reports.

Obstacles standing in the way of cancer prevention

More than half of all cancer is preventable, and society has the knowledge to act on this information today, according to Washington University public health researchers at the Siteman Cancer Center in St. Louis.

AHF calls on FDA Commissioner Hamburg to step down

AIDS Healthcare Foundation (AHF), the nation's largest HIV/AIDS organization, today called on Food and Drug Administration (FDA) Commissioner Margaret Hamburg to step down in response to the agency's gross mismanagement of new product reviews and a lack of transparency.

FDA approves Avioq HTLV-I/II Microelisa System

Avioq, Inc. announced it has received approval from the U.S. Food and Drug Administration (FDA) for the Avioq HTLV-I/II Microelisa System. The test is used for the qualitative detection of antibodies to Human T-Lymphotropic Virus Type I (HTLV-I) and Human T-Lymphotropic Virus Type II (HTLV-II) in human serum or plasma.

Study: 20.1M individuals infected with HEV across 9 world regions

New research funded by the World Health Organization (WHO) estimates that 20.1 million individuals were infected with hepatitis E virus (HEV) genotypes 1 and 2 across 9 world regions in 2005.

New microfluidic chip more effective in detecting flu outbreaks

The H1N1 flu pandemic in 2009 underscored weaknesses in methods widely used to diagnose the flu, from frequent false negatives to long wait times for results. Now Boston University researchers have developed a prototype of a rapid, low-cost, accurate, point-of-care device that promises to provide clinicians with an effective tool to quickly diagnose both seasonal and pandemic strains of influenza, and thus limit the spread of infection.

Gold nanoparticles used to introduce chemical residues into the immune system

Developing a drug or vaccine requires a delicate balancing act with the immune system. On one hand, medications need to escape detection by the immune system in order to perform their function. But vaccinations - de-activated versions of a disease or virus - need to do the reverse. They prompt the immune system to create protective antibodies.

National biosecurity panel to hold closed-door meeting on bird flu research

The National Science Advisory Board for Biosecurity (NSABB) is scheduled this week to hold "a closed-door meeting to once again look at unpublished manuscripts describing" two studies that showed how H5N1 bird flu virus could be manipulated to become transmissible among ferrets, a model for humans, NPR's health blog "Shots" reports, noting that the meeting "will include a classified briefing from the intelligence community."

NY-ESO-1 vaccine shows promise against ovarian cancer, melanoma

An immunotherapy regimen incorporating poxviruses and targeting a particular tumor antigen, NY-ESO-1, has shown promise in treating two types of cancers.

MedImmune receives FDA approval for FluMist Quadrivalent vaccine

FluMist Quadrivalent, a vaccine to prevent seasonal influenza in people ages 2 years through 49 years, has been approved today by the U.S. Food and Drug Administration. FluMist Quadrivalent is the first influenza vaccine to contain four strains of the influenza virus, two influenza A strains and two influenza B strains.

Nanoscale sensor can conduct individual DNA sequencing

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.

Study reveals how HSV-1 virus overcomes intrinsic host defenses

New biological research reveals how an invading virus hijacks a cell's workings by imitating a signaling marker to defeat the body's defenses. By manipulating cell signals, the virus destroys a defensive protein designed to inhibit it. This finding, from studies in human cell cultures, may represent a broader targeting strategy used by other viruses, and may lay the scientific groundwork for developing more effective treatments for infectious diseases.
