Reports that a team of researchers from the Centers for Disease Control and Prevention in Atlanta, Georgia, has confirmed the molecular structure of the avian influenza virus present in Hong Kong. Identification of the virus; Human infection from the virus; Transfer of the virus between humans....
Researchers from Oxford University have worked out the molecular structure of a protein that is vital for survival of the flu virus. Recently published inNature, they used several different techniques to look at the arrangement of atoms within a protein that the human flu virus uses to make new...
Nearly all maternofetal and fetomaternal exchange takes place in the placental villi. There is only a limited contribution by the extraplacental membranes. In addition, most metabolic and endocrine activities of the placenta have been localized in the villi (for review see Gröschel-Stewart, 1981...
A team of scientists from The Scripps Research Institute and other institutions has solved the structure of a key protein from the virus that caused last year's "swine flu" influenza epidemic. The structure reveals that the virus shares many features with influenza viruses common in the early 20...
In addition to the protein coat, some viruses have specialized structures. For example, the flu virus has a membrane-like envelope around its capsid. These viruses are known as enveloped viruses. The envelope has both host cell and viral components and assists the virus in infecting its host....
The vaccines that children are given are meant to prevent their getting sick. One of the vaccines they get is the MMR shot, meant to prevent...
The team has found that this virus uses the same protein to switch between genome replication and transcription. "It gets both jobs done with one enzyme. The virus's genome is so small, and this gives it economy of scale," said Lamb....
RNAs perform their function by forming specific structures, which can change across cellular conditions. Structure probing experiments combined with next generation sequencing technology have enabled transcriptome-wide analysis of RNA secondary structure
We used cryo-EM to reconstruct the map of the EV-F4 capsid at a resolution of 2.96 Å and build an atomic model. The overall structure closely resembles EV-F3 but exhibits several differences in its capsid surface. 2. Materials and Methods 2.1. Virus Purification Possum EV-F4 virus was ...
The influenza virus is complicated and continuous mutation makes it difficult to eradicate, and highly infectious. Learn different types of...
