Fathers biologically attuned to their children when sleeping nearby, research reveals Posted: 07 Sep 2012 01:52 PM PDT Mothers aren't the only ones who are biologically adapted to respond to children. New research shows that dads who sleep near their children experience a drop in testosterone. Previous research from humans and other species suggests this decrease might make men more responsive to their children's needs and help them focus on the demands of parenthood.

Coping skills, marital satisfaction help pregnant moms manage stress when fetus has heart defect Posted: 07 Sep 2012 01:06 PM PDT Expectant mothers who learn from prenatal diagnosis that they are carrying a fetus with a congenital heart defect (CHD) commonly suffer post-traumatic stress, depression and anxiety. However, a healthy relationship with one's partner and positive coping mechanisms can reduce this intense stress, according to new research.

Precautions for tick-borne disease extend 'beyond Lyme' Posted: 07 Sep 2012 11:23 AM PDT This year's mild winter and early spring were a bonanza for tick populations in the eastern United States. Reports of tick-borne disease rose fast. While Lyme disease is the most common tick-borne disease in the Northeast and Upper Midwest, new research results emphasize that it is not the greatest cause for concern in most Southeastern states.

First appropriate use criteria in dermatology released Posted: 07 Sep 2012 11:20 AM PDT A new manuscript co-published in the Journal of the American Academy of Dermatology and Dermatologic Surgery outlines Appropriate Use Criteria (AUC) for Mohs surgery – the first AUC for any test or treatment within the field of dermatology.

First look at structure of vital molecule Posted: 07 Sep 2012 10:16 AM PDT Molybdenum is an essential metal required in all living beings from bacteria to plants to humans. But as vital as this metal is, no one understood the importance of the structure of a vital molecule that interacts with molybdenum until now.

Exposure to bisphenol A (BPA) early in life results in high levels of anxiety; Soy mitigates effects, study shows Posted: 07 Sep 2012 10:16 AM PDT New research led by researchers at North Carolina State University shows that exposure to the chemical bisphenol A early in life results in high levels of anxiety by causing significant gene expression changes in a specific region of the brain called the amygdala. The researchers also found that a soy-rich diet can mitigate these effects.

Work with germ-killing copper could save thousands of lives Posted: 07 Sep 2012 10:15 AM PDT When Adam Estelle graduated from the University of Arizona's materials science and engineering program four years ago, he had no idea he would be involved in saving thousands of lives. Now, Estelle is working with technology based on copper alloys that kill bacteria, fungi and viruses. The metals can be fashioned into everything from IV poles to sinks to bed rails -- just about anything that is frequently touched in hospitals.

Child abuse and discipline: What’s the difference? Posted: 07 Sep 2012 10:15 AM PDT A researcher is attempting to differentiate child abuse from physical discipline through an examination of Chinese-American mothers and pediatric nurses.

Hockey and football concussions: Time for big changes, expert argues Posted: 07 Sep 2012 10:15 AM PDT Imagine ice hockey without body checking and football with less hitting. What might sound blasphemous to hockey and football fans and players could protect youngsters from potentially deadly concussions, an expert argues.

Novel surgery removes rare tumor, rebuilds face and jaw Posted: 07 Sep 2012 09:51 AM PDT Using a novel surgical approach, it's possible to rebuild a functional lower jaw and mouth, and preserve a patient's ability to eat and speak after removing an invasive facial tumor, according to a new report.

Stress prompts some to retain as much salt as eating fries, study finds Posted: 07 Sep 2012 09:50 AM PDT When stressed, about 30 percent of blacks hold onto too much sodium, the equivalent of eating a small order of fast food French fries or a small bag of potato chips, according to new research.

Allegedly useless parts of the human genome fulfil regulatory tasks Posted: 07 Sep 2012 09:47 AM PDT Heidelberg scientists contribute to the encyclopedia of all functional DNA elements in the human genome.

Antibiotics improve exacerbations of mild-to-moderate COPD Posted: 07 Sep 2012 09:47 AM PDT Antibiotic treatment with amoxicillin/clavulanate improves moderate exacerbations in patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) and significantly prolongs the time between exacerbations, according to a new study.

Strategy developed to improve delivery of medicines to the brain Posted: 07 Sep 2012 06:55 AM PDT New research offers a possible strategy for treating central nervous system diseases, such as brain and spinal cord injury, brain cancer, epilepsy, and neurological complications of HIV. The experimental treatment method allows small therapeutic agents to safely cross the blood-brain barrier in laboratory rats by turning off P-glycoprotein, one of the main gatekeepers preventing medicinal drugs from reaching their intended targets in the brain.

Alzheimer's experts provide strategic roadmap Posted: 07 Sep 2012 06:55 AM PDT This week, a strategic roadmap to help to the United States' health care system cope with the impending public health crisis caused Alzheimer's disease and related dementia will be published. The plan aims to link the latest scientific findings with clinical care and bring together patients, families, scientists, pharmaceutical companies, regulatory agencies, and advocacy organizations behind a common set of prioritized goals.

Experts recommend screening adults for hypertriglyceridemia every five years Posted: 07 Sep 2012 06:55 AM PDT The Endocrine Society has issued a Clinical Practice Guideline (CPG) for the diagnosis and treatment of hypertriglyceridemia. Triglycerides are a type of fat found in the blood and are associated with cardiovascular risk.

Measuring glucose without needle pricks Posted: 07 Sep 2012 05:20 AM PDT Pricking a finger everyday is just part of everyday life for many diabetes patients. A non-invasive measurement approach could release them from the constant pain of pin pricks. The linchpin is a biosensor engineered by researchers in Germany: A tiny chip combines measurement and digital analysis -- and can be radioed to a mobile device.

Can dynamic mapping reveal clues about flu seasonality? Posted: 07 Sep 2012 05:16 AM PDT Influenza outbreaks in the United States typically begin with the arrival of cold weather and then spread in seasonal waves across geographic zones. But the question of why epidemics can vary from one season to the next has baffled scientists. A new study suggests that the search for answers has been thwarted, in part, by the lack of standardized research methods.

Melanoma manifests differently in children than in adults, study finds Posted: 07 Sep 2012 04:24 AM PDT Physicians studying melanoma and related conditions occurring in childhood recently published results of their experience with cases of pathologically confirmed childhood melanoma. They found evidence that the disease manifests differently in children than in adults, particularly with regard to the likelihood and significance of lymph node metastases.

Prenatal diagnosis of congenital heart disease increases maternal stress, depression, and anxiety Posted: 07 Sep 2012 04:24 AM PDT Infants who were prenatally diagnosed with congenital heart disease (CHD) are more stable and have better outcomes than infants who were diagnosed after birth. Diagnosing CHD in a fetus also allows mothers to educate themselves on heart malformations, consider their options, and potentially plan for intervention or surgery after birth. However, a new study finds that, along with these benefits, maternal post-traumatic stress, depression, and anxiety are common after prenatal diagnosis of CHD.

'Hidden’ alcohol abuse among older people revealed Posted: 07 Sep 2012 04:23 AM PDT A study has uncovered a growing drink problem among older people. Researchers have been assessing the extent of alcohol abuse among the older generation which often results from big changes such as retirement, bereavement, feelings of boredom, loneliness and depression.

Red flag raised on offbeat hearts Posted: 07 Sep 2012 04:18 AM PDT An estimated 2.5 million Americans suffer from irregular heartbeats -- also known as atrial fibrillation. The incidence of this potentially life changing cardiovascular condition is on the rise and expected to more than double by 2050.

Raised antibody levels linked to greater long term risk of rheumatoid arthritis Posted: 06 Sep 2012 04:08 PM PDT Men and women with raised levels of an antibody known as rheumatoid factor in their blood have up to a 26-fold greater long term risk of developing rheumatoid arthritis, a new study finds.

Diagnostic chest radiation before age 30 may increase breast cancer risk in BRCA1/2 mutation carriers Posted: 06 Sep 2012 04:08 PM PDT Women carrying a mutation in the BRCA1 or BRCA2 genes (which control the suppression of breast and ovarian cancer) who have undergone diagnostic radiation to the chest before the age of 30 are more likely to develop breast cancer than those who carry the gene mutation but who have not been exposed, a new study reveals.
