The very unexpected life and death of a leukemic cell

...9 individuals with CLL a small dose of heavy water every day for 84 days, and the tagged water was incorporated into the DNA of the leukemia cells. This provided the researchers a way to track the cell division, or "birth" of new leukemia cells. Chiorazzi and his team calculated birth and death rates of th...

Research Using Mouse Models Reveals A Novel Key Player In The Initiation Of Colon Cancer

...s account for more than 1 million deaths worldwide every year and several research groups have been working to identify the molecular events that result in the initiation and progression of these tumors. It has been established that interfering with the function of one gene, called Adenomatous Polyposis Co...

Boosting HIV screening can increase survival and is cost effective

.... They found that routine, voluntary HIV screening every three to five years is cost-effective by U.S. standards, in all but the lowest-risk populations. Frequent HIV screening in moderate-to-high-risk populations could produce life expectancy gains at costs that compare favorably to many commonly employed...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...ogists to identify the precise subunit sequence of every gene in the genomes of everything from malaria pathogens and mosquitoes to mouse and human. Databases of genomic information have been combined with databases that list the precise subunit sequence of proteins as well. Cross-species DNA and protein c...

Falling ants glide back to trunk to avoid dangers of forest floor

...rboreal Pseudomyrmecinae ants. "It turns out that every species in the genus Cephalotes that I've dropped so far shows this gliding behavior, and they are by far the best gliders," Yanoviak said. But the long, cylindrical wasp-like Pseudomyrmecinae ants are also pretty good at it, as are several species o...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...ey are the foundation of the cellular structure of every living organism, Lamont said. They carry on the day-to-day biology of life, going about their business as enzymes and antibodies. They can also cause disease. “The genes themselves are only important in that they encode the proteins,?Lamont said. “I...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...body rituximab. These treatments are usually given every three weeks over a span of up to six months and can cause many unpleasant side effects, including nausea, hair loss and infections.

Migratory Monarchs seem more resistant than non-migratory ones to parasite infections; scientists just uncovered why it is so. Explanation : infected monarchs quite don't make it while migrating long dista...

FDA Approves New Drug to Treat Type I and Type II Diabetes

Symlin should not be used if patients cannot tell when their blood sugar is low, have gastroparesis (slow stomach emptying), or are allergic to pramlintide acetate, metacre...

Rush Physicians Using Gene Therapy For Heart Patients With Moderate To Severe Chest Pains Who Do Not Benefit From Other Treatments

...he is receiving the gene therapy or a placebo. For every three patients that receive the active gene, one will receive a placebo. Following treatment, patients enrolled in the study will be examined for chest pain at one month, three months and six months. A total of 404 patients will be enrolled in the st...

After months of painstaking detective work, PCRM research analyst Megha Even, M.S., working with BiosPacific, an Emoryville, California, lab, succeeded in culturing cells using an animal component-free, peptide- and protein-free, media supplem...

International HapMap consortium expands mapping effort

Cricket's finicky mating behavior boosts biodiversity

...zed Laupala spawns new species at the rate of 4.17 every 1 million years, or more than 10 times faster than the average speciation rate for invertebrates. This rapid evolution is contributing to an "explosion" of new cricket species, especially on Hawaii, the largest and youngest island in the Hawaiian arc...
