Cases of one of the world's deadliest diseases–tuberculosis–are rising at an alarming rate, despite widespread vaccination. Reasons for the ineffectiveness of the vaccine, especially in regions where this infectious disease is endemic, as well as arguments for replacing the existing vaccine with novel synthetic vaccines, are presented in a review published online August 28th in Trends in Molecular Medicine. "Tuberculosis is a global health threat, and it is a highly...

Novel vaccine additive to enhance the body's immune response shows promise in mice Oxford University scientists have discovered a compound that greatly boosts the effect of vaccines against viruses like flu, HIV and herpes in mice. An 'adjuvant' is a substance added to a vaccine to enhance the immune response and offer better protection against infection. The Oxford University team, along with Swedish and US colleagues, have shown that a type of polymer called polyethyleneimine (PEI)...

Numerous viruses are used in the service of science today. They serve as gene taxis to transfer therapeutic genes into body cells or as therapeutic viruses targeted to infect and destroy cancer cells. For such applications, the viruses are often equipped with additional genes, such as for immune mediators or for proteins inducing programmed cell death. However, these gene products can harm the body if they are released at the wrong moment or at excessive levels. "Ideally, we want to be able...

Poxviruses Adapt Quickly To Fight Host Of Viral Defenses
2012-08-17 12:28:52

Connie K. Ho for redOrbit.com — Your Universe Online Researchers recently discovered how poxviruses, viruses that contain DNA, can change quickly; in particular, they have an “accordion-like” way of viral adaption to fight against host viral defenses. Poxviruses, which include smallpox, can lead to a number of diseases in both humans and animals. They are seen as harmful, as they can pass through the species barrier with low mutation rates. Recently, there has been...

Research Uncovers Deadly Snake Disease
2012-08-14 13:50:37

Lee Rannals for redOrbit.com — Your Universe Online A deadly disease outbreak that devastates boa constrictors and pythons has been discovered, which scientists call Inclusion Body Disease (IBD). This disease outbreak among snakes is being investigated by scientists at the Steinhart Aquarium in San Francisco. The team said they may have found a virus that is responsible for this common, but deadly disease, which could ultimately help lead to prevention and treatment options....

Women comprise nearly half of the HIV-infected population worldwide, but these 15.5 million women tend to be under-represented in clinical trials of anti-HIV drug therapies. The U.S. Food and Drug Administration (FDA) has created a database from 40 clinical studies to assess gender differences in the efficacy of antiretroviral treatments. The results of this study are presented in an article in AIDS Patient Care and STDs, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The...

New research published in Nature Medicine describes a unique nanoparticle-releasing microparticle oral vaccine delivery system for HIV. Alachua, FL (PRWEB) August 09, 2012 Nanotherapeutics, Inc. announced today the publication of a paper, authored by Jay Berzofsky and colleagues (Q. Zhu et al, doi:10.1038/nm.2866) at the National Cancer Institute (NCI), in the August 2012 issue of Nature Medicine, which describes a unique nanoparticle-releasing microparticle oral vaccine delivery system....

Amazonians Exposed To Vampire Bat Bites Have Natural Immunity To Rabies
2012-08-02 10:35:19

Lawrence LeBlond for redOrbit.com - Your Universe Online US scientists studying indigenous tribes in the Amazon have found six native Peruvian Amazonians who, after being bitten by rabid vampire bats, suffered no ill effects. Rabies infections from vampire bat bites are quite common in the Amazon region. And in many of the indigenous tribes, most infections are fatal due to lack of access to proper medical treatment. Rabies attacks the central nervous system (brain and spinal cord)...

Virology Journal
2012-04-24 18:40:35

Virology Journal is an open-access peer-reviewed medical journal published by BioMed Central. It covers research related to viruses and the prevention of viral infection (including vaccination, the use of antiviral agents, and gene therapy). Virology Journal was established in 2004 and is edited by Robert F. Garry. The goal of the journal is to cover rapid communications amongst virologists. The journal has not been published without controversy, however. On 21, July 2010, the journal...

Virology is a peer-reviewed academic journal covering basic research into viruses affecting animals, plants, bacteria and fungi. It includes the molecular biology, structure, assembly, pathogenesis, immunity and interactions viruses have with the host cell. The journal also covers aspects of control and prevention, as well as viral vectors and gene therapy. Virology was established in 1955 and is now published bi-weekly by the Academic Press imprint of Elsevier. Subscribers of Virology...

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...

Vesicular stomatitis virus (VSV) is a virus in the family Rhabdoviridae. Rabies is in the same family. VSV infects insects and animals and is important to farmers in certain regions of the world where it can infect cattle. It is a common laboratory virus used for studying the Rhabdoviridae family and viral evolution. It is the prototypic member of the vesiculovirus genera of the Rhabdovirus family. The genome is a single molecule of negative-sense RNA that encodes five major proteins.

Tobacco mosaic virus (TMV) is a positive-sense single stranded RNA virus that infects plants, namely tobacco and other members of the family Solanaceae. It causes characteristic patterns on the leaves. In 1930 it was determined that an infectious agent was determined to be a virus. Adolf Mayer first described the disease in 1883. The disease can be transferred between plants similar to bacterial infections. Dimitri Ivanovski was the first to show that infected sap remained infectious even...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
