University researchers investigate the role of corticosterone in signaling fetal distress

A University of Calgary researcher has identified how a steroid hormone may indicate infant distress during labour and delivery. The study, published by PLOS ONE this month, suggests that a full-term, healthy baby preferentially secretes a different stress hormone than its mother does. That stress hormone, corticosterone, has not been previously studied in human development.

Scientists discover molecular pathway that can prevent death of oocytes due to chemotherapy

Young women who have cancer treatment often lose their fertility because chemotherapy and radiation can damage or kill their immature ovarian eggs, called oocytes. Now, Northwestern Medicine- scientists have found the molecular pathway that can prevent the death of immature ovarian eggs due to chemotherapy, potentially preserving fertility and endocrine function.

MCL-1 protein is vital for normal heart function, shows study

A study by researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences and the Department of Pharmacology at the University of California, San Diego, shows that a protein called MCL-1, which promotes cell survival, is essential for normal heart function.

Study: Infants secrete different stress hormone than their mothers during labor and delivery

During labor and delivery, infants preferentially secrete a different stress hormone than their mothers do, according to a new clinical study. The results will be presented Saturday at The Endocrine Society's 95th Annual Meeting in San Francisco and published in the open access journal, PLoS One.

Viewpoints: Don't change course on Medicare reforms on medical equipment prices; Liberals' agenda depends on cutting entitlements; Making hospital prices public

Marilyn Tavenner has been administrator of Medicare and Medicaid officially for only about a month, but already she faces a policy challenge from Congress. A majority of the House, 145 Republicans and 82 Democrats, wrote to Ms. Tavenner on Wednesday, asking her to delay implementation of a Medicare cost-reduction initiative, scheduled to take full effect July 1, for six months.

Targeting SALL4 protein with druglike molecules could halt tumor growth, say researchers

Harvard Stem Cell Institute researchers have identified in the most aggressive forms of cancer a gene known to regulate embryonic stem cell self-renewal, beginning a creative search for a drug that can block its activity.

MGH researchers discover CNVs in members of 10 families with early-onset Alzheimer's

Although a family history of Alzheimer's disease is a primary risk factor for the devastating neurological disorder, mutations in only three genes - the amyloid precursor protein and presenilins 1 and 2 - have been established as causative for inherited, early-onset Alzheimer's, accounting for about half of such cases.

Researchers use patient-specific stem cells to correct deficient insulin-producing cells

A team from the New York Stem Cell Foundation Research Institute and the Naomi Berrie Diabetes Center of Columbia University has generated patient-specific beta cells, or insulin-producing cells, that accurately reflect the features of maturity-onset diabetes of the young.

New study identifies possible treatment to block deposition of calcium in arterial wall

HGPS is a rare genetic disease that affects one in every 4-8 million births. The disease is caused by a spontaneous mutation in one of the two copies (alleles) of the gene LMNA, which codes for lamin A, a protein important for the integrity and function of the envelope surrounding the cell nucleus. The mutation causes incorrect processing of the messenger RNA for lamin proteins, resulting in the synthesis of an anomalous protein, called progerin.

HPV antibodies may help identify individuals at increased risk of HPV-related oropharynx cancer

Researchers have found that antibodies against the human papillomavirus (HPV) may help identify individuals who are at greatly increased risk of HPV-related cancer of the oropharynx, which is a portion of the throat that contains the tonsils.

Drug increases amount of energy burned by fat tissue and promotes weight loss

A drug that mimics the activity of thyroid hormone significantly increases the amount of energy burned by fat tissue and promotes weight loss, an animal study of metabolism finds. The results were presented Sunday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Early exposure to BPA increases risk for prostate cancer in human prostate tissue

Early exposure to BPA (bisphenol A) - an additive commonly found in plastic water bottles and soup can liners - causes an increased cancer risk in an animal model of human prostate cancer, according to University of Illinois at Chicago researcher Gail Prins.

Mannitol could prevent aggregation of toxic proteins in the brain, says Tel Aviv University researcher

Mannitol, a sugar alcohol produced by fungi, bacteria, and algae, is a common component of sugar-free gum and candy. The sweetener is also used in the medical field - it's approved by the FDA as a diuretic to flush out excess fluids and used during surgery as a substance that opens the blood/brain barrier to ease the passage of other drugs.
