Consumers not getting accurate information about smokeless tobacco

Information on the internet about the health risks associated with the consumption of smokeless tobacco usually overstates the risk. This is the conclusion of research published today in the Open Access journal BMC Public Health, entitled “You might as well smoke; the misleading and harmful public message about smokeless tobacco”. A study of 316 internet websites showed that most government, health advice, and advocacy websites suggested that smokeless tobacco use is as harmful as cigarette smok

Immune cells in the liver take a ride

Scientists at New York University School of Medicine viewing the actual journey of immune cells in the liver have found that these cells travel in the liver’s blood vessels with surprising speed and agility.

It is the first time that the movement of live immune cells called natural killer T (NKT) cells has been seen in the liver, according to a study published in the April 5, 2005, issue of the Public Library of Science, an open-access, online journal.

NKT cells ar

Searching the depths of the straits of Florida for disease cures

Harbor Branch Biomedical Expedition to include first submersible exploration of remote Cay Sal Bank

On Monday, the Harbor Branch drug discovery group will begin a 2-week expedition to explore the Straits of Florida in search of organisms that produce chemicals with the potential to cure diseases such as cancer and Alzheimer’s. The work will include the first submersible exploration of the remote Cay Sal Bank, which encompasses a number of small, uninhabited islands 30 mile

US-India research team completes analysis of X chromosome

Dozens of new genes identified

By intensely and systematically comparing the human X chromosome to genetic information from chimpanzees, rats and mice, a team of scientists from the United States and India has uncovered dozens of new genes, many of which are located in regions of the chromosome already tied to disease.

Regions of the X chromosome, one of the two sex chromosomes (Y is the other), have been linked to mental retardation and numerous other disorders, but find

Natural tumor suppressor in body discovered by UCSD medical researchers

A natural tumor suppressor that could potentially be turned on in certain cancer cells to prevent the formation of tumors has been discovered by researchers at the University of California, San Diego (UCSD) School of Medicine.

Located on chromosome 18 and called PH domain Leucine-rich repeat Protein Phosphatase (PHLPP, pronounced “flip”), the tumor suppressor is described in the April 1, 2005 issue of the journal Molecular Cell. The scientists demonstrated that PHLPP deletes a p

Scientists find missing enzyme for tuberculosis iron scavenging pathway

Scientists have discovered that a protein that was originally believed to be involved in tuberculosis antibiotic resistance is actually a “missing enzyme” from the biosynthetic pathway for an agent used by the bacteria to scavenge iron.

The research appears as the “Paper of the Week” in the April 8 issue of the Journal of Biological Chemistry, an American Society for Biochemistry and Molecular Biology journal.
