University of Cincinnati New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher rate than the currently used filtering technology made of activated carbon. In the journal “Nano Letters,” Vikram Kapoor, environmental engineering doctoral student, and David Wendell, assistant...
Researchers at the Bonn University Hospital have deciphered the underlying mechanism of an antiviral drug A long-forgotten candidate for antiviral therapy is undergoing a renaissance: Since the 1970s, the small molecule CMA has been considered a potent agent against viral infections, yet it was never approved for clinical use. Scientists at the Bonn University Hospital have now deciphered how the molecule can actually stimulate the immune system to combat viruses. The results are now being...
How well people are protected by the smallpox vaccine depends on more than the quality of the vaccination: individual genes can alter their response, Mayo Clinic research shows. The findings, gathered using sophisticated genomic screening, appear in today's online issue of the journal Genes and Immunity. "We were looking into the intercellular reactions that occur when vaccinated and unvaccinated persons are exposed to and infected with smallpox virus. We were able to use blood samples...
A key building block in the Schmallenberg virus could be targeted by anti-viral drugs, according to a new study led from the University of Leeds. The disease, which causes birth defects and stillbirths in sheep, goats and cattle, was first discovered in Germany in late 2011 and has already spread to more than 5,000 farms across Europe, and 1,500 farms in the UK alone. There is currently no way of treating infected animals, but a study published in Nucleic Acids Research reports that the...
LONDON, April 18, 2013 /PRNewswire/ -- Replikins Ltd will reveal details on the availability of two completely synthetic vaccine candidates, both with long-term prevention goals and acute short-term blocking capacity. One of these vaccines targets H7N9 alone, the other for H7N9 plus the other common influenza strains. The company is exploring partnerships with established healthcare and pharmaceutical companies to aggressively commercialize the technology. Because Replikins is...
polyDNA recommends using Gene-Eden-VIR to protect against genital herpes. Rochester, NY (PRWEB) April 17, 2013 polyDNA’s monthly survey shows that many in the public are unaware of the recommended ways of preventing genital herpes. In the open comments section of the survey, a typical response was offered by Shari C. from Raleigh, N.C. “I have been dating a really great guy who recently told me he has herpes (got it from his ex-wife). I don't have herpes and I don't a lot...
The human body has the ability to ward off viruses by activating a naturally occurring protein at the cellular level, setting off a chain reaction that disrupts the levels of cholesterol required in cell membranes to enable viruses to enter cells. The findings, discovered by researchers in molecular microbiology and immunology at the Keck School of Medicine of USC, hold promise for the development of therapies to fight a variety of viral infections. "Previous studies have shown that our...
Study examines changes in the penis microbiome Male circumcision reduces the abundance of bacteria living on the penis and might help explain why circumcision offers men some protection against HIV, according to a study led by the Translational Genomics Research Institute (TGen). Removing the foreskin caused a significant shift in the bacterial community or microbiome of the penis, according to a study published today by the online journal mBio. This international collaboration...
SAN DIEGO, April 16, 2013 /PRNewswire/ -- Aethlon Medical, Inc. (OTCQB: AEMD), today released the following note authored by its Chairman and CEO, Jim Joyce. As disclosed in yesterday's SEC form 8-K submission, we entered into a subcontract agreement with Battelle Memorial Institute (Battelle) to provide services underlying a $22.8 million prime contract that was recently awarded to Battelle by the Defense Advanced Research Projects Agency (DARPA). The objective of this contract...
New data on T cells' protective role suggests need for new approach to dengue vaccine design As efforts to create a strong and effective vaccine for the dreaded dengue virus continue to hit snags, a new study from researchers at the La Jolla Institute for Allergy & Immunology offers surprising evidence that suggests the need for a revamped approach to dengue vaccine design. The finding runs counter to current scientific understanding of the key cells that need to be induced to develop...

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...
Rubella virus is the cause of congenital rubella syndrome when infection occurs during the first weeks of pregnancy. Humans are the only known host of this virus. It is the only member of the genus of Rubivirus and belongs to the family of Togaviridae. Members of the Togaviridae family typically have a genome of single-stranded RNA of positive polarity which is enclosed by an icosahedral capsid. This genome has a length of about 9,757 nucleotides and encodes for two non-structural as well...
A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses have been described in detail although there are millions of different types. They are found in...
Vaccinia virus (VACV or VV) is a large, complex, enveloped virus belonging to the poxvirus family. It is well-known for its role in eradicating smallpox. It was the first human disease to to successfully be eradicated by science. The World Health Organization was the one who completed the endeavor. The vaccinia virus saw renewed interest in the early 21st century due to concerns about the smallpox virus being used as an agent for bioterrorism. They can be divided into four types:...
Simian immunodeficiency virus (SIV), also known as African Green Monkey virus, is a retrovirus able to infect at least 33 species of African primates. SIV has been present in monkeys and apes for at least 32,000 years, probably longer. Strains from two of these primate species have crossed the barriers into humans resulting in HIV-2 and HIV-1. Contraction involves contact with the blood of chimps that are often hunted for bushmeat in Africa. SIV infections appear in many cases to be...
