Scientists identify critical molecule that helps explain why diabetics suffer from non-healing wound

One of the most troubling complications of diabetes is its effect on wound healing. Roughly 15 percent of diabetics will suffer from a non-healing wound in their lifetime. In some cases, these open ulcers on the skin lead to amputations.

Oatmeal breakfast results in greater fullness, lower hunger ratings and fewer calories intake at lunch

A new study suggests that your breakfast cereal choice may affect how full you feel and how much you eat for lunch, especially if you're overweight. According to new research published in the latest issue of the Annals of Nutrition and Metabolism, scientists found that having oatmeal (Quaker Oats Quick 1-minute™) for breakfast resulted in greater fullness, lower hunger ratings and fewer calories eaten at the next meal compared to a calorie-matched breakfast of a ready-to-eat cereal (RTEC) - sugared corn flakes.

Researchers probe possibility of reversing medications' adverse cognitive effects

Whether the adverse cognitive effects of medications can be reversed is of significant importance to an aging population, their caregivers and their families, as well as to an overburdened health care system.

Hutchinson-Gilford Progeria Syndrome can be compared to normal aging, say scientists

In a new research study, scientists from Vision Genomics, LLC, Insilico Medicine, Inc., and Howard University showed that Hutchinson-Gilford Progeria Syndrome (HGPS or Progeria) is comparable to normal aging with respect to cellular signaling pathways, and that HGPS truly recapitulates the normal aging process.

Silencing neurons in the arcopallium

New research published by the Neuronal Mechanism for Critical Period Unit at the Okinawa Institute of Science and Technology Graduate University has shown the effectiveness of chemogenetic inhibition used to suppress neuronal activity as well as interesting results on how vocalization is controlled through this techniques application in zebra finches.

Lund researchers find new way to identify malignant tumours in children

A research group at Lund University in Sweden has found a new way to identify the most malignant tumours in children. The method involves studying genetic 'micro-variation', rather than the presence of individual mutations.

Combating pre-pregnancy obesity helps both mother and child

Before a woman gets pregnant it is very common for her to plan and prepare for her child's arrival to ensure that the baby will benefit from the healthiest, most comfortable life possible. Sometimes, these preparations may be financial or they may involve taking such important healthcare steps as quitting smoking. Now, according to data from the Swedish Medical Birth Register, one of the best things that a mother can do for the health of her child is to ensure that she is at a healthy weight.

Improving prefrontal cortex activity could help autistic people regulate emotions

Tantrums, irritability, self-injury, depression, anxiety. These symptoms are associated with autism, but they're not considered core symptoms of the disorder. Researchers from the UNC School of Medicine are challenging this assertion. They have used functional MRI to show that - when it comes to the ability to regulate emotions - brain activity in autistic people is significantly different than brain activity in people without autism.

Study: Targeted biopsy technique better than standard biopsy at detecting high-risk prostate cancer

Among men undergoing biopsy for suspected prostate cancer, targeted magnetic resonance/ultrasound fusion biopsy, compared with a standard biopsy technique, was associated with increased detection of high-risk prostate cancer and decreased detection of low-risk prostate cancer, according to a study in the January 27 issue of JAMA.

Researchers explore KRAS pathway to find potential target for treating lung cancer

Despite the promise of the gene KRAS as a target for treating lung cancer, finding effective therapies has been challenging. Now researchers are traveling down the pathway to find what makes KRAS cancerous.

Study finds that African-American people with colon cancer have lower survival rates

African-American people diagnosed with colon cancer have consistently lower survival rates compared with white patients, despite a nationwide decline in colon cancer deaths overall.

Study provides new route for treating patients with difficult-to-treat Parkinson's symptoms

Parkinson's disease patients treated with low-frequency deep brain stimulation show significant improvements in swallowing dysfunction and freezing of gait over typical high-frequency treatment.

Developmental salivary biomarkers linked to feeding success in newborns

Results from a study published online in the Journal of Pediatrics hold the potential to substantially improve clinical decision-making to determine when a premature newborn is ready for oral feeding. The study describes developmental salivary biomarkers associated with feeding success in newborns, markers that could lead to development of objective assessment tools for caregivers.

Ghrelin hormone supplement increases sexual activity in mice

Swedish studies show that mice that receive a supplement of the "appetite hormone" ghrelin increase their sexual activity. Whether the hormone has the same impact on humans is unknown - but if it does, the researchers may have found the key to future treatments for sex abuse.

Research explores effect of DBS treatments in animals with brain injuries

The research, published in Behavioural Brain Research, was conducted by Pilar Segura and Ignacio Morgado (coordinators), Laura Aldavert and Marc Ramoneda, psychobiologists of the Institute of Neurosciences and the Department of Psychobiology and Health Sciences Methodology of the UAB and by Elisabet Kadar and Gemma Huguet, molecular biologists of the University of Girona, to explore the power of Deep Brain Stimulation treatments in the hypothalamus to recover the ability to learn and remember after a severe lesion of the amygdala.
