Research reveals surprisingly complex protein-coding capacity of human cytomegalovirus

New findings reveal the surprisingly complex protein-coding capacity of the human cytomegalovirus, or HCMV, and provide the first steps toward understanding how the virus manipulates human cells during infection. The genome of the HCMV was first sequenced over 20 years ago, but researchers have now investigated the proteome-the complete set of expressed proteins-of this common pathogen as well.

Major advance in understanding how flu viruses replicate within infected cells

Scientists at The Scripps Research Institute (TSRI) have made a major advance in understanding how flu viruses replicate within infected cells. The researchers used cutting-edge molecular biology and electron-microscopy techniques to "see" one of influenza's essential protein complexes in unprecedented detail. The images generated in the study show flu virus proteins in the act of self-replication, highlighting the virus's vulnerabilities that are sure to be of interest to drug developers.

Online flu survey launched in the UK

Does “man flu” exist? How effective is the flu vaccine? And do pets keep you healthy? These are just some of the questions scientists from the London School of Hygiene & Tropical Medicine want to explore as they launch a nationwide flu survey.

Single dose of Medicago's vaccine could offer cross-protection against flu

Researchers recently found that a single dose of a vaccine being developed by Medicago, Inc., a publicly traded biopharmaceutical company, could protect against not only the avian influenza (H5N1) strain it was designed for, but also another H5N1 strain and a strain of a different flu subtype, called H2N2.

Microbiologists discover how the spread of antibiotic resistance works in pneumococcus

Antibiotic resistance results from bacteria's uncanny ability to morph and adapt, outwitting pharmaceuticals that are supposed to kill them. But exactly how the bacteria acquire and spread that resistance inside individuals carrying them is not well-established for most bacterial organisms.

UNAIDS report indicates end to AIDS possible but challenges remain

UNAIDS' World AIDS Day report: Results, released on Tuesday, said the goal of eventually ending the global AIDS epidemic "is more than merely visionary" and "is entirely feasible," primarily because of "historic success" in scaling up HIV programs and improving access to antiretroviral drugs to treat and prevent HIV, Reuters reports.

Genetic study: Novel coronavirus most closely related to viruses in bats

The virus that is causing alarm among global public health authorities after it killed a man in Jeddah, Saudi Arabia earlier this year and is now linked to two other cases of disease is a novel type of coronavirus most closely related to viruses found in bats, according to a genetic analysis to be published in mBio-, the online open-access journal of the American Society for Microbiology, on November 20.

Panel backs routine HIV screenings for teens, adults

The U.S. Preventive Services Task Force advises that nearly everyone ages 15 to 64 should be screened for the HIV virus, a recommendation which, if adopted, would require Medicare and most private health insurers to pay for the tests.

Novartis receives FDA approval for Flucelvax to prevent seasonal influenza

The U.S. Food and Drug Administration announced today the approval of Flucelvax, the first seasonal influenza vaccine licensed in the United States produced using cultured animal cells, instead of fertilized chicken eggs. Flucelvax is approved to prevent seasonal influenza in people ages 18 years and older.

Texas Biomed applies patent for new genetically-engineered vaccine strategy to prevent HIV

The Texas Biomedical Research Institute in San Antonio has applied for a patent for a genetically-engineered vaccine strategy to prevent HIV infection that targets the outer layers of body structures that are the first sites of contact with the virus.

GSK receives FDA approval for PROMACTA to treat thrombocytopenia

GlaxoSmithKline plc announced today that the U.S. Food and Drug Administration (FDA) has approved PROMACTA for the treatment of thrombocytopenia (low blood platelet counts) in patients with chronic hepatitis C to allow them to initiate and maintain interferon-based therapy.

New fiber-optic device can deliver light to the brain in 3D

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of Technology (MIT) in Cambridge, is the first tool that can deliver precise points of light to a 3-D section of living brain tissue. The work is a step forward for a relatively new but promising technique that uses gene therapy to turn individual brain cells on and off with light.

HCV medications' side effects can now be replicated and observed in Petri dishes and test tubes

The adverse side effects of certain hepatitis C medications can now be replicated and observed in Petri dishes and test tubes, thanks to a research team led by Craig Cameron, the Paul Berg Professor of Biochemistry and Molecular Biology at Penn State University.

GigaScience announces publication of whole-genome sequencing and analysis of Wuzhishan Pig

The international open-access journal GigaScience announces the publication of the whole-genome sequencing and analysis of the Wuzhishan Pig, an extensively inbred, miniature pig, which can serve as an excellent model for human medical research.

Number of polio cases worldwide reaches record low, but experts say challenges remain

"The number of polio cases worldwide reached a record low in 2012, giving experts confidence that the disease can finally be eradicated, according to presentations made at" the annual meeting of the American Society of Tropical Medicine and Hygiene (ASTMH) in Atlanta on Tuesday, Agence France-Presse reports (11/13).

Is it safe to drink alcohol when taking antibiotics?

In the lead up to summer party season, NPS MedicineWise is reminding Australians that while alcohol might not interact with many antibiotics, it’s still important to follow certain rules for taking antibiotics correctly.

Flu virus suppresses body's ability to defend against bacteria

When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host's immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome - and then signals scavenger cells of the immune system to ingest fewer bacteria.

Viruses to treat metastatic cancers

There exists a "type" of cancer that is common yet rarely discussed—metastatic cancer, or cancer that has spread from the part of the body where it originated (the primary tumor) to another (such as lungs, bones or liver). Although much research is being done to combat primary tumors, there still exists a crucial need to find a treatment that can be effective against metastatic cancer, or "mets." Could a virus be the answer that finally beats the mets?
