Key signs of appendicitis

A 5-year-old with abdominal pain, nausea and fever may have appendicitis or any of a number of other problems.

Discredited Korean embryonic stem cells' true origins revealed

A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells.

Violence associated with disorders of arousal

Disorders of arousal (i.e., sleepwalking, confusional arousals and sleep terrors) have sometimes been associated with violent behaviors against other individuals.

Worldwide distribution of cervical cancer virus is consistent with vaccine targets

The variety of human papilloma viruses that cause invasive cervical cancer cases worldwide are largely consistent across continents, according to a new study from the University of North Carolina at Chapel Hill.

Possible anthrax drug targets

In the American government's biodefense efforts, the potential for terrorists to cause a deadly anthrax outbreak remains a significant concern, six years after the letter attacks that shook the nation shortly after 9/11.

Gene variation makes people with depression more likely to respond to the medication citalopram

A variation in a gene called GRIK4 appears to make people with depression more likely to respond to the medication citalopram (Celexa) than are people without the variation, a study by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, has found.

Discovery of molecular pathway that detects and eliminates defective messenger RNAs from red blood cells

Other such pathways - known as surveillance pathways - operate in a more general way, in many cell types. Knowing how this specific surveillance system works can help researchers better understand hereditary diseases, in this case, thalassemia, a form of anemia, which is the most common genetic disorder worldwide.

Autonomous glial mechanism may drive circadian rhythms

Glial cells of the nervous system, once thought to function strictly as support cells for neurons, are now thought to actively modulate them.

Colon cancer may benefit from hormone replacement therapy

Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have found new evidence suggesting that colon cancer is actually a disease of missing hormones that could potentially be treated by hormone replacement therapy.

Aggressive therapy best for certain acute myeloid leukemia patients

A new study suggests that acute leukemia patients whose cancer cells show a genetic change that usually predicts a swift return of the disease following remission may remain disease-free longer when given aggressive therapy.

Biological markers of narcolepsy

The first report to identify the biological markers of narcolepsy using gene expression in white blood cells finds that the MX2 gene, which is relevant to the immune system, is significantly less expressed in narcoleptics compared with normal subjects.

Drugs designed to disable enzyme TOPK could have anti-cancer benefits

Working with human colorectal cancer cells, a University of Minnesota team, led by cancer biologists Zigang Dong and Ann Bode, has found the potential culprit among a network of enzymes that relay signals inside cells to regulate such functions as cell growth, cancer development and programmed cell death.

Screening MRI allows detection of more breast cancers in high-risk women

Magnetic resonance imaging (MRI) enables radiologists to accurately identify tumors missed by mammography and ultrasound, according to a multicenter study comparing the three screening methods in women at high-risk for breast cancer.

Novavax begins human clinical testing of novel pandemic flu vaccine

Novavax has announced that it has begun vaccinating healthy volunteers in the first human clinical trial of its virus-like particle ("VLP") based pandemic influenza vaccine.

Bipolar disorder phenome database

A novel, free, public online database opening this week should greatly speed efforts to find genes linked to increase risk of bipolar disorder.

Hallucinations in schizophrenia linked to brain area that regulates emotion and processes human voices

For the first time, researchers using magnetic resonance imaging (MRI) have found both structural and functional abnormalities in specific brain regions of schizophrenic patients who experience chronic auditory hallucinations, according to a study published in the August issue of Radiology.

Xenomics issued European patent for Transrenal Nucleic Acid Technology for Prenatal Diagnostics

Xenomics, Inc. has announced the issuance of its first European patent "Methods for detection of nucleic acid sequences in urine", EP 1634966 A2 that covers use of its proprietary transrenal nucleic acid technology in the area of prenatal diagnostics and genetic testing.

Discovery of pathway that controls cell size and division

Organisms precisely regulate cell size to ensure that daughter cells have sufficient cellular material to thrive or to create specific cell types: a tiny sperm versus a gargantuan egg for example.

New risk genes for multiple sclerosis

Two new large-scale genomic studies have honed in on the main genetic pathway associated with multiple sclerosis (MS), while also uncovering new genetic variations in the disease and suggesting a possible link between MS and other autoimmune diseases.

Interferon-alpha levels may predict who might be at risk to develop lupus

Certain families produce higher levels of a specific molecule, called interferon-alpha, that primes the body's immune system to turn on, and in some cases initiate an autoimmune attack on itself, according to new research from Hospital for Special Surgery in New York City.
