Scientists discover that host cell lipids facilitate bacterial movement

When the bacterium Listeria monocytogenes invades the body, it commandeers its host cell's actin cytoskeleton to invade other cells. In a report published in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique. The research appears as the "Paper of the Week" in the March 25 issue of the Journal of Biologic...

Liposome finding implies electrical effect on cell development

Experiments with liposomes ?cell-like "water balloons" composed of artificially created phospholipid bilayers similar to natural cell membranes ?have revealed unexpected behavior in the presence of electrical fields that may provide a paradigm-shifting change in science's understanding of biomembrane function in operating living systems. Arizona State University chemists Mark Hayes and Mic...

Purdue researchers use enzyme to clip 'DNA wires'

Researchers at Purdue University have attached magnetic "nanoparticles" to DNA and then cut these "DNA wires" into pieces, offering the promise of creating low-cost, self-assembling devices for future computers. Findings are detailed in a paper published online in February in the Journal of the American Chemical Society. The paper was written by Purdue graduate student Joseph M. Kinsella...

Lipids get new comprehensive classification system

In response to the growing number of lipids expected to be discovered through lipidomics and in anticipation of the massive amounts of data that will be generated by the lipid community, an international group of scientists has developed a comprehensive classification, nomenclature, and chemical representation system for lipids. The details of the system appear in the May issue of the Journal of...

The flip side of AIDS cocktails – HAART regime damages live

HIV infected patients on highly active antiretroviral therapy (HAART regime) are forced to stop the treatment because of the toxic side effects of the treatment, which causes liver damage. According to a study led by Dr. Raymond T. Chung, who presented the findings at Digestive Disease Week in Atlanta last week, severe liver toxicity forced almost one in every four patients to stop the t...

Cleft lip and palate are due to abnormality in brain structure

Clefts of the lip and palate are associated with permutation in brain structure that appear to cause cognitive dysfunction, according to a study recently conducted by researchers at the University of Iowa.// Studying 54 adult men with nonsyndromic facial clefts and 54 male control subjects, the researchers used magnetic resonance imaging to study brain volume and tissue composition. T...

FDA considers nicotine lollipops illegal

The Food and Drug Administration cracked down on Internet distributors of nicotine-laced lollipops and lip balm, declaring them illegal and ordering that 4 pharmacies stop sales immediately. The lollipops in particular pose a risk to children because they look like regular candy, the FDA warned. "The quantity of nicotine could be potentially dangerous to a small child," said FDA attorney...

Unfavourable Lipid-Lipoprotein profiles in older adults has been linked to abdominal visceral fat

According to investigators from the Department of Human Services at the University of Virginia, in persons over 60 years of age, elevated levels of abdominal visceral fat are associated with unfavourable plasma concentrations of lipids and lipoproteins. Abdominal fat was also found to be a primary determinant in the release of growth hormone in these individuals. The investigators assesse...

Cleft Lip And Cleft Palate Can Now Be Predicted Before Birth

About one in every 600 babies in the United States is born with an isolated cleft lip and palate, which means the baby is born with cleft only // and no other birth defects. Researchers say they now have a new gene test that will help predict if a couple will have a child born with a cleft lip and palate one of the world’s most common birth defects. According to researchers isolated clef...

Analyzers Offer Point-of-Care Lipid Panels

Plasma lipids, comprised of triglycerides and cholesterols, vary with genetic predisposition, weight, diet and physical activity. All of these factors contribute to serum cholesterol and triglyceride levels and highly correlate with risk of untoward vascular and cardiac events. Perhaps no other commonly determined medical laboratory values are so much in the public eye as serum levels of good...
