UV rays help prevent spread of chickenpox

Ultraviolet rays help prevent the spread of chickenpox, meaning people in milder climates are more at risk of catching the disease, according to new research. The discovery could lead to new ways of preventing chickenpox and its more severe relative, shingles.

First mobile safety lab for South African patients with AIDS and TB

The first mobile safety laboratory to operate under Biosafety Level 3 has been in use in South Africa since May 2011. As development of the Fraunhofer Institute for Biomedical Engineering in St. Ingbert, this special truck is used for testing and advising patients with AIDS and tuberculosis. The mobile laboratory can save patients' lives in remote areas because it cuts the waiting time between diagnosis and the start of treatment to just one day.

Researchers discover novel viral oncogenesis mechanism

Human tumor viruses contribute to 15-20% of human cancers worldwide. Kaposi's sarcoma herpesvirus (KSHV) is an etiological agent for Kaposi's sarcoma (KS) and two other rare lymphoproliferative malignancies. KS is the most common cancer in HIV-infected untreated individuals and remains a primary cause of cancer deaths in many subequatorial African countries as a result of the AIDS pandemic.

Liver transplantations for NASH-Cirrhosis increase dramatically

Nonalcoholic steatohepatitis (NASH) occurs when fat builds up in the liver. This accumulation of fat damages the liver and leads to cirrhosis. NASH is rapidly increasing in the U.S. mainly related to the epidemics of obesity and diabetes.

Fresh cells can pep talk immune cells exhausted by HIV or hepatitis C

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion.

U.S. investments in HIV treatment internationally, domestically 'should pay off'

"We welcome the Obama administration's announcement of a farsighted effort to treat millions more people living with HIV abroad, especially in sub-Saharan Africa," a New York Times editorial writes.

New substance can replace nucleoside thymidine in DNA biosynthesis

Interactions of biological macromolecules are the central bases of living systems. Biological macromolecules are synthesized in living cells by linking many small molecules together. Naturally occurring macromolecules include genetic materials (DNA) and proteins. A detailed understanding of the synthesis of these macromolecules in whole animals is a basic requirement for understanding biological systems, and for the development of new therapeutic strategies.

Aethlon Hemopurifier can capture Nef protein exosomes linked with HIV

Aethlon Medical, Inc., the pioneer in developing therapeutic filtration devices to address infectious disease and cancer, announced today that researchers have discovered that the Aethlon Hemopurifier is able to capture particles known as Nef protein exosomes, which contribute to the progression of human immunodeficiency virus (HIV) infection to acquired immunodeficiency syndrome.

Study describes new method that synthesizes novel anti-HIV protein

The most abundant and important molecules in all living organisms are proteins; after all they manage to participate in every single one of life's essential reactions. So it is easy to see why scientists have been making such a fuss trying to learn how to synthesise them in laboratory as this would provide them with a tool of extraordinary potential. Unfortunately, this has not proved easy.

Viewpoints: Blocking an abortion option for military women; Plan B pushback; Solving Wis. doc shortage

Republican Senate leaders have an odd way of showing gratitude for the dedication and sacrifices of the more than 200,000 women on active duty in the military. Late last month, they blocked consideration of an amendment to the National Defense Authorization Act that would have lifted the statutory ban that denies female service members coverage for abortion care in cases of rape and incest.

Gene therapy for bleeding disorder Hemophilia B

In a landmark study, researchers used gene therapy to successfully treat six patients with severe hemophilia, a blood-clotting disorder. Despite the early nature of the study, it is promising. A single infusion using the new treatment worked in some patients for more than a year, boosting their clotting ability significantly.

Gene therapy can reduce painful bleeding episodes in patients with hemophilia B

Symptoms improved significantly in adults with the bleeding disorder hemophilia B following a single treatment with gene therapy developed by researchers at St. Jude Children's Research Hospital in Memphis and demonstrated to be safe in a clinical trial conducted at the University College London (UCL) in the U.K.

Experimental sublingual vaccine shows promise against influenza infection

Scientists from the International Vaccine Institute (IVI) have discovered that an antigen common to most influenza viruses, and commonly referred to as matrix protein 2 (M2), when administered under the tongue could protect mice against experimental infection caused by various influenza viruses, including the highly pathogenic avian H5 virus and the pandemic H1 ("swine flu") virus.

Enrollment complete in Boehringer Ingelheim's BI 201335 Phase III trial for HCV

Boehringer Ingelheim today announced that the final patient has been randomised to treatment in the large-scale Phase III clinical trial programme for BI 201335, its investigational, oral protease inhibitor for the treatment of chronic hepatitis C virus.

Recommendations to address challenges associated with chronic inflammatory diseases

A dramatic increase in the incidence of chronic inflammatory diseases such as asthma, allergy, and irritable bowel syndrome, has led to concern about how modern lifestyles may trigger physiological defense mechanisms.

New gene editing technique can heal sickle cell patients with their own cells

Researchers at the Salk Institute for Biological Studies have developed a way to use patients' own cells to potentially cure sickle cell disease and many other disorders caused by mutations in a gene that helps produce blood hemoglobin.

PrEP shows promise against HIV infection

A new weapon has emerged to prevent HIV infection. Called pre-exposure prophylaxis, or PrEP, it is a strategy of providing medications to at-risk people before they are exposed to the virus. Having shown great promise in recent phase 3 clinical trials, PrEP may soon be rolled out for public use.
