LONDON, July 7, 2014 /PRNewswire/ -- Reportbuyer.com has added a new market research report:
Researchers at the University of Warwick have sequenced an ancient RNA genome for the first time ever. The RNA belonged to a barley virus once thought to be just 150 years old, but has now been determined to date back at least 2,000 years.
HIV infection has many unhealthy consequences on the body, but in particular it messes up the gut.
In the summer of 2010, the eastern Panamanian province of Darien experienced a phenomenon that had never been seen before in Latin America: a human outbreak of eastern equine encephalitis.
A large scale, five year study of mosquitoes from different ecological regions in Kenya, including savannah grassland, semi-arid Acacia thorn bushes, and mangrove swamps, found a reservoir of viruses carried by mosquitoes (arboviruses) that are responsible for human and animal diseases.
Researchers have learned the atomic-scale arrangement of proteins in a structure that enables a virus to invade and fuse with host cells, showing precisely how the structure morphs with changing acidity to initiate infection.
In a discovery that has implications for developing treatments against cancer and potentially deadly viruses, researchers at SUNY Downstate Medical Center have discovered the function of proteins that can enhance the progression of certain viruses and cancer cells.
There are several challenges to be overcome if therapeutic anticancer vaccines, which are designed to boost the patient's anticancer immune response, are to be successfully developed.
An experimental vaccine based on a virus that causes encephalitis in the wild appears to block tumor growth in some cases of advanced cancer.
Mosquito-borne virus has infected millions of people in Asia, Africa and Europe.
The Semliki Forest virus was isolated from mosquitoes in the Semliki Forest in 1942. It can cause disease in both animals and man. It's an Alphavirus found in central, eastern, and southern Africa. It is a positive-stranded RNA virus. It is spread mainly by mosquito bites and infects mammals through inhalation or gastrointestinal exposure. The virus can cause lethal encephalitis in rodents; however, only one fatal infection has been reported in humans. This patient was immunodeficient and...
Eastern equine encephalitis virus (EEE), also called sleeping sickness or Triple E, is a zoonotic alphavirus and arbovirus that exists in the Americas and the Caribbean. It was first seen in Massachusetts in 1831 when 75 horses died of encephalitic illness. It is often associated with coastal plains. EEE was first isolated from the brain of an infected horse in 1933. In 1938 the first human case was confirmed when thirty children died of encephalitis in northeaster United States...
