Study: Effects of testosterone on brain's response to threat cues in healthy men

A new study in Biological Psychiatry reports on a neural circuit for male aggression. Testosterone, a steroid hormone, is well known to contribute to aggressive behavior in males, but the neural circuits through which testosterone exerts these effects have not been clear.

Research: New ways to help visually impaired better navigate everyday life

Visual impairment comes in many forms, and it's on the rise in America. A University of Cincinnati experiment aimed at this diverse and growing population could spark development of advanced tools to help all the aging baby boomers, injured veterans, diabetics and white-cane-wielding pedestrians navigate the blurred edges of everyday life.

New mechanism of joint destruction grinds away healthy cartilage, worsens osteoarthritis

A new mechanism of joint destruction caused by a natural material that grinds away healthy cartilage and worsens osteoarthritis has been identified in human hip joints for the first time by University of Liverpool scientists.

Midlife hypertension link to later-life cognitive decline strengthened

Analysis of the Atherosclerosis Risk in Communities study cohort supports an association between elevated blood pressure in midlife and increased cognitive decline in older age.

Researchers awarded $3.3 million NIH grant to study role of genetics in protecting against frailty

Frailty is a common condition associated with old age, characterized by weight loss, weakness, decreased activity level and reduced mobility, which together increase the risk of injury and death. Yet, not all elderly people become frail; some remain vigorous and robust well into old-age.

Study: Younger and older adults show same responses for spatial attention tasks

At least one part of the human brain may be able to process information the same way in older age as it does in the prime of life, according to new research conducted at the University of Adelaide.

New disposable device may help doctors to monitor post-operative ileus

A disposal, plastic listening device that attaches to the abdomen may help doctors definitively determine which post-operative patients should be fed and which should not, an invention that may improve outcomes, decrease healthcare costs and shorten hospital stays, according to a UCLA study.

Scientists uncover new information on how stem cells in human bowel behave

For the first time, scientists have uncovered new information on how stem cells in the human bowel behave, revealing vital clues about the earliest stages in bowel cancer development and how we may begin to prevent it.

Scientists analyze genetic characteristics of cancers using multiple genomic technology platforms

New research partly led by UC San Francisco-affiliated scientists suggests that one in 10 cancer patients would be more accurately diagnosed if their tumors were defined by cellular and molecular criteria rather than by the tissues in which they originated, and that this information, in turn, could lead to more appropriate treatments.

People who develop depression, MCI after age 65 are more vulnerable for accelerated brain aging

People who develop depression and mild cognitive impairment (MCI) after age 65 are more likely to have biological and brain imaging markers that reflect a greater vulnerability for accelerated brain aging, according to a study conducted by researchers at the University of Pittsburgh School of Medicine. The findings were published online in Molecular Psychiatry.

Secret of aging skin may lie in glycan and micronutrient creams

For decades, dermatologists have been researching the genetic cause of aging skin so that the perfect antidote could be developed. When examining genes and proteins, a difference between younger and older looking skin has not been found.

Research report on the U.S. spinal implant market

Decision Resources Group finds that the United States spinal implant market will expand modestly through 2022 to reach a value of nearly $7.1 billion.

People diagnosed with MCI are more likely to increase risk of developing dementia

In a long-term, large-scale population-based study of individuals aged 55 years or older in the general population researchers found that those diagnosed with mild cognitive impairment (MCI) had a four-fold increased risk of developing dementia or Alzheimer's disease (AD) compared to cognitively healthy individuals.

Study shows noticeable differences in brain function across the day for older adults

Older adults who are tested at their optimal time of day (the morning), not only perform better on demanding cognitive tasks but also activate the same brain networks responsible for paying attention and suppressing distraction as younger adults, according to Canadian researchers.

UH Case Medical Center implants new type of cochlear device in patients with hearing problem

University Hospitals Case Medical Center is the first in Cleveland to implant a new type of cochlear device for adults who have lost the high frequency range of their hearing, but have retained the low frequencies with or without a hearing aid.

Induced immunorejection may eliminate tumors post-cell transplantation

Recent studies have shown that transplanting induced pluripotent stem cell-derived neural stem cells (iPS-NSCs) can promote functional recovery after spinal cord injury in rodents and non-human primates. However, a serious drawback to the transplantation of iPS-NSCs is the potential for tumor growth, or tumorogenesis, post-transplantation.
