The genes are composed of DNA and are carried on the chromosomes. Genes direct the production of all the molecules that form the structures that of a cell. Genes determine the inherited characteristics that distinguish one individual from another. Each human has an estimated 90,000 genes.
Parabens in breast tissue not limited to women who have used underarm products – New research into the potential link between parabens and breast cancer has found traces of the chemicals in breast tissue samples from all of the women in the study. Parabens are commonly used as preservatives in cosmetics, food products and pharmaceuticals.
Proteins do not predict outcome of herceptin treatment in HER2-positive breast cancer – Precisely quantifying the amount of three different HER growth proteins, along with several other proteins believed linked to breast cancer, did not predict a patient’s outcome after treatment for HER2 Positive Breast Cancer with Herceptin, say Mayo Clinic researchers.
New gene study of ADHD points to defects in brain signaling pathways — Children’s Hospital of Philadelphia research suggests that interventions at the glutamate transmission level might treat ADHD disorder – Pediatric researchers analyzing genetic influences in attention-deficit/hyperactivity disorder (ADHD) have found alterations in specific genes involved in important brain signaling pathways.
Fatty acids involved in python heart growth could benefit diseased human heart – Now, Burmese python’s heart may diseased human hearts, revealed by researchers from University of Alabama, USA. Three fatty acids involved in the extreme growth of Burmese pythons’ hearts following large meals could prove beneficial in treating diseased human hearts.
Understanding the beginnings of embryonic stem cells helps predict the future – Ordinarily, embryonic stem cells exist only a day or two as they begin the formation of the embryo itself. Then they are gone. In the laboratory dish, however, they act more like perpetual stem cells ? renewing themselves and exhibiting the ability to form cells of almost any type, a status called totipotency.
‘Alarm clock’ gene explains wake-up function of biological clock — Finding promising insight into sleeplessness, aging and chronic illness, such as diabetes and cancer – Ever wondered why you wake up in the morning – even when the alarm clock isn’t making jarring noises? Wonder no more. Researchers at the Salk Institute for Biological Studies have identified a new component of the biological clock, a gene responsible for starting the clock from its restful state every morning.
CSHL team finds evidence for the genetic basis of autism — Models of autism show that gene copy number controls brain structure and behavior – Scientists at Cold Spring Harbor Laboratory (CSHL) have discovered that one of the most common genetic alterations in autism — deletion of a 27-gene cluster on chromosome 16 — causes autism-like features.
FDA confirms Listeria monocytogenes on Jensen Farms? Rocky Ford-brand cantaloupes — Jensen Farms voluntarily recalled product last week in response to outbreak – US Food and Drug Administration announced that it found Listeria monocytogenes in samples of Jensen Farms’ Rocky Ford-brand cantaloupe taken from a Denver-area store and on samples taken from equipment and cantaloupe at the Jensen Farms’ packing facility.
FDA warns consumers not to eat Rocky Ford Cantaloupes shipped by Jensen Farms – Jensen Farms recalls Rocky Ford cantaloupe due to potential link to a multi-state outbreak of listeriosis – US FDA is warning consumers not to eat Rocky Ford Cantaloupe shipped by Jensen Farms of Granada, Colo. The majority of the patients reported eating cantaloupe marketed from the Rocky Ford growing region. FDA’s traceback data from the State of Colorado about their confirmed cases of Listeria monocytogenes have identified a common producer of Rocky Ford cantaloupes. That producer is Jensen Farms. Although the investigation is ongoing, no other Rocky Ford cantaloupe producer has been found in common in the Colorado traceback.
FDA investigates multistate outbreak of listeriosis – The U.S. Food and Drug Administration is working closely with the Centers for Disease Control and Prevention and state health agencies to investigate a multi-state outbreak of listeriosis.
Study reveals critical similarity between two types of do-it-all stem cells – Researchers saw substantial similarity between the two stem-cell types – pluripotent stem cells and embryonic stem cells, reported in a new study.
Lead researcher, Dr Manuel Ferreira from QIMR said the findings suggest that a drug currently used to treat rheumatoid arthritis may be effective to treat asthma. – Asthma sufferers now can be treated with a drug used to treat rheumatoid arthritis, revealed by researchers in a new study.
