New book on evolution and future of human reproduction

Human beings would probably be known as pilosals rather than mammals if Carl Linnaeus had not been a proponent of breast-feeding. For social and political reasons, the famed taxonomist labeled the class of animals to which humans belong with a reference to their practice of suckling their young rather than to their evolutionarily older characteristic of having hair.

Genetics may play role in how people's taste receptors send signals

Genetics may play a role in how people's taste receptors send signals, leading to a wide spectrum of taste preferences, according to Penn State food scientists. These varied, genetically influenced responses may mean that food and drink companies will need a range of artificial sweeteners to accommodate different consumer tastes.

Glucagon loses its ability to help obese people, but continues to suppress hunger pangs

Glucagon, a hormone involved in regulating appetite, loses its ability to help obese people feel full after a meal, but it continues to suppress hunger pangs in people with type 1 diabetes, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Study shows how brain integrates inputs from different senses in complex circuits of nerve cells

A new publication in the top-ranked journal Neuron sheds new light onto the unknown processes on how the brain integrates the inputs from the different senses in the complex circuits formed by molecularly distinct types of nerve cells. The work was led by new Ume- University associate professor Paolo Medini.

UC Davis graduate discovers how eIF4E protein acts upon cancer-promoting mRNA molecules

Researchers have long known that high levels of a specific protein in human cells are linked to tumor growth - but no one has fully understood how.

Research suggests gene therapy approach may be feasible option to treat Rett Syndrome

The concept behind gene therapy is simple: deliver a healthy gene to compensate for one that is mutated. New research published today in the Journal of Neuroscience suggests this approach may eventually be a feasible option to treat Rett Syndrome, the most disabling of the autism spectrum disorders.

Studies reveal potential of HB-EGF in protecting intestines from diverse types of injury

It's not often that one treatment offers therapeutic potential for multiple conditions. However, after more than two decades of research, Gail Besner, MD, principal investigator for the Center for Perinatal Research and pediatric surgeon for the Department of Pediatric Surgery at Nationwide Children's Hospital, and her team have found that this may just be the case with HB-EGF, or heparin-binding EGF-like growth factor.

Study shows ERs are not meeting needs of senior citizens

Emergency departments are not meeting the needs of senior citizens, according to a new international study published in the Annals of Emergency Medicine.

Study: Pregnant women with gestational diabetes lose over an hour of sleep each night

Women diagnosed with gestational diabetes are nearly seven times more likely to have obstructive sleep apnea than other pregnant women, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Sodium act as "on/off" switch for major neurotransmitter receptor in brain

Researchers at McGill University have found that sodium - the main chemical component in table salt - is a unique "on/off" switch for a major neurotransmitter receptor in the brain. This receptor, known as the kainate receptor, is fundamental for normal brain function and is implicated in numerous diseases, such as epilepsy and neuropathic pain.

Study shows continuous CSF drainage is associated with complications in patients with SAH

Researchers at Duke University conducted a randomized clinical trial in patients with subarachnoid hemorrhage (SAH). In this study, the researchers compared two approaches to intracranial pressure management-continuous and intermittent drainage of cerebrospinal fluid (CSF)-and outcomes associated with those methods, focusing specifically on the incidence of cerebral vasospasm.

Even in advanced stages total tumor size can have major impact on survival in lung cancer patients

For the two-thirds of lung cancer patients with locally advanced or metastatic disease, tumor size is not used currently to predict overall survival times. A new study, however, led by UT Southwestern Medical Center researchers has shown that even in advanced stages total tumor size can have a major impact on survival.

3-D structure of proteins show flame retardants can mimic estrogen hormones

By determining the three-dimensional structure of proteins at the atomic level, researchers at the National Institutes of Health have discovered how some commonly used flame retardants, called brominated flame retardants (BFRs), can mimic estrogen hormones and possibly disrupt the body's endocrine system. BFRs are chemicals added or applied to materials to slow or prevent the start or growth of fire.

RNA biomarkers in blood may identify people at risk for committing suicide

Indiana University School of Medicine researchers have found a series of RNA biomarkers in blood that may help identify who is at risk for committing suicide.

More patients suffer from complications after cancer surgery, but only few die

While more patients in the U.S. are suffering from complications such as blood clots and infections after major cancer surgery, fewer are dying from their operations.

Research: 2 forms of iron to treat cystic fibrosis lung infection

The bacterium Pseudomonas aeruginosa needs iron to establish and maintain a biofilm in the lungs of cystic fibrosis patients, and therapies have been proposed to deprive the bacteria of this necessary element.

Researchers identify key transcription factor linked with treatment-resistant prostate cancer

Prostate cancer is one of the most common forms of cancer in men and the leading cause of cancer deaths in white, African-American and Hispanic men, according to the Centers for Disease Control. Current treatment of prostate cancer targets androgens, hormones which promote the growth and spread of cancer cells.

Scientist study irregular brain activity during concussion recovery with fMRI

For the first time, researchers have documented irregular brain activity within the first 24 hours of a concussive injury, as well as an increased level of brain activity weeks later-suggesting that the brain may compensate for the injury during the recovery time.

New drug-delivery strategy for central vision loss

Johns Hopkins biomedical engineers have teamed up with clinicians to create a new drug-delivery strategy for a type of central vision loss caused by blood vessel growth at the back of the eye, where such growth should not occur.

Children with high BPA levels have higher odds of obesity and abnormal waist circumference

Children who have higher levels of Bisphenol A (BPA), a chemical previously used in many products for kids, like baby bottle and plastic toys, had a higher odds of obesity and adverse levels of body fat, according to a new study from University of Michigan researchers.
