AICAR might protect against heat stress in MH-susceptible individuals

Malignant hyperthermia (MH) is a life-threatening genetic muscle disorder, most commonly triggered in those at risk by certain types of drugs used during anesthesia. Heat stroke, on the other hand, most commonly occurs in individuals in response to physical exertion in hot/humid environments. While their common triggers may differ, the signs associated with MH and heat stroke are remarkably similar - uncontrolled muscle contractions, dangerous increases in body temperature, and muscle breakdown leading to the release of toxins in the blood which may cause cardiac arrhythmias and death. Immediate treatment for these conditions is crucial.

Researchers identify human receptor that can taste fat

Why do we like fatty foods so much? We can blame our taste buds. Our tongues apparently recognize and have an affinity for fat, according to researchers at Washington University School of Medicine in St. Louis. They have found that variations in a gene can make people more or less sensitive to the taste of fat.

Age, marital status affect risk of going on medical leave or disability pension

Factors other than genetics and childhood environment affect the risk of going on medical leave or disability pension, reports a study in the January Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine.

Study shows how Notch gene and PRC2 protein complex work together to cause T-ALL

A new study published in the journal Nature Medicine by NYU Cancer Institute researchers, shows how the cancer causing gene Notch, in combination with a mutated Polycomb Repressive Complex 2 (PRC2) protein complex, work together to cause T- cell acute lymphoblastic leukemia.

Clinical trial to compare Aria's prenatal test and standard first-trimester screening for T21

Aria Diagnostics, a molecular diagnostics company, announced that it is initiating a blinded, multicenter clinical trial that compares its non-invasive prenatal test with the standard first-trimester screening test (serum screening and nuchal translucency ultrasound alone and in combination) to detect Trisomy 21, which is associated with Down syndrome.

Lack of iron early in life can affect brain's physical structure

Iron is a popular topic in health news. Doctors prescribe it for medical reasons, and it's available over the counter as a dietary supplement. And while it's known that too little iron can result in cognitive problems, it's also known that too much promotes neurodegenerative diseases. Now, researchers at UCLA have found that in addition to causing cognitive problems, a lack of iron early in life can affect the brain's physical structure as well.

Genetic link to prostate cancer discovered

A new study has found that men who inherit a rare genetic mutation are 10 to 20 times more likely than average to develop prostate cancer. The gene variant may help explain cases of the disease that run in families and strike men at unusually young ages.

New NIST clinical SRM can help in accurate CMV detection and treatment

A new clinical Standard Reference Material (SRM) from the National Institute of Standards and Technology (NIST) will help health care professionals more accurately diagnose and treat cytomegalovirus (CMV), a common pathogen that is particularly dangerous for infants and persons with weakened immune systems.

GnuBIO to complete development of SCD genetic panel

GnuBIO, Inc., a pioneer in scalable desktop DNA sequencing and the Montreal Heart Institute (MHI) have announced today that they will complete the development of a genetic panel in order to screen patients to determine the risk for sudden cardiac death, SCD.

First details of genetic alterations that fuel early T-cell precursor ALL

Researchers have discovered that a subtype of leukemia characterized by a poor prognosis is fueled by mutations in pathways distinctly different from a seemingly similar leukemia associated with a much better outcome. The findings from the St. Jude Children's Research Hospital - Washington University Pediatric Cancer Genome Project (PCGP) highlight a possible new strategy for treating patients with this more aggressive cancer.

Study confirms condom use reduces risk of HIV infection by 78%

The level of HIV-1 in the blood of an HIV-infected partner is the single most important factor influencing risk of sexual transmission to an uninfected partner, according to a multinational study of heterosexual couples in sub-Saharan Africa.

Chemotherapy drugs can lead to relapse of leukemia

The chemotherapy drugs required to push a common form of adult leukemia into remission may contribute to DNA damage that can lead to a relapse of the disease in some patients, findings of a new study suggest.

Scientists identify rare genetic mutation linked to prostate cancer

After a 20-year quest to find a genetic driver for prostate cancer that strikes men at younger ages and runs in families, researchers have identified a rare, inherited mutation linked to a significantly higher risk of the disease.

St. Jude introduces 'Explore' website for pediatric genome project

St. Jude Children's Research Hospital has launched a freely available website for published research results from the St. Jude Children's Research Hospital - Washington University Pediatric Cancer Genome Project (PCGP). The PCGP is the largest effort to date aimed at sequencing the entire genomes of both normal and cancer cells from pediatric cancer patients, comparing differences in the DNA to identify genetic mistakes that lead to childhood cancers.

Researchers identify mechanism that makes retinoblastoma so aggressive

New findings from the St. Jude Children's Research Hospital - Washington University Pediatric Cancer Genome Project (PCGP) have helped identify the mechanism that makes the childhood eye tumor retinoblastoma so aggressive. The discovery explains why the tumor develops so rapidly while other cancers can take years or even decades to form.

DNA may be used to predict lifespan: Study

Researchers may soon be able to predict how long a person will live based on their genetics. This could result from the discovery by a University of Glasgow team in Scotland showing that telomere length on the ends of DNA in their genes in early-life predicts life spans.

DNA decoder – cheaper and faster

Life Technologies Corp. – a biotechnology company announced Tuesday that it has developed a machine to decode an individual's DNA in a day for just $1,000. The company said it was taking orders for the technology, which it expects to deliver in about a year. The Carlsbad, California, company said three major research institutions had already signed up for the $149,000 machine: the Baylor College of Medicine, the Yale School of Medicine and the Broad Institute of Cambridge, Massachusetts.

Researchers analyze microorganisms in human gut as a complex, integrated biological system

For the first time, researchers have analyzed the multitude of microorganisms residing in the human gut as a complex, integrated biological system, rather than a set of separate species. Their approach has revealed patterns that correspond with excess body weight.

Potential human health risk from illegal wildlife trade

An article released today in PLoS ONE entitled, Zoonotic Viruses Associated with Illegally Imported Wildlife Products, from a collaborative study led by the U.S. Centers for Disease Control and Prevention (CDC), identified evidence of retroviruses and herpesviruses in illegally imported wildlife products confiscated at several U.S. international airports, including John F. Kennedy International Airport, George Bush Intercontinental-Houston and Atlanta Hartsfield-Jackson International.
