One of the earliest known impairments caused by Alzheimer's disease - loss of sense of smell — can be restored by removing a plaque-forming protein in a mouse model of the disease, a study led by a Case Western Reserve University School of Medicine researcher finds. The study confirms that the protein, called amyloid beta, causes the loss. "The evidence indicates we can use the sense of smell to determine if someone may get Alzheimer's disease, and use changes in sense of smell to...

Case Western Reserve study published in November issue of Journal of Studies on Alcohol and Drugs also highlights the influence of religious practices on treatment response A new study of teens undergoing substance abuse treatment finds helping others helps the adolescent helper by reducing cravings for alcohol and drugs, a major precipitator of relapse. These novel findings stem from the "Helping Others" study (http://helpingotherslivesober.org) led by Maria Pagano, PhD, associate...

A hard probe inserted in the cerebral cortex of a rat model turns nearly as pliable as the surrounding gray matter in minutes, and induces less of the tough scarring that walls off hard probes that do not change, researchers at Case Western Reserve University have found. In the first test of the nanocomposite probe inspired by the dynamic skin of the sea cucumber, the immune response differed compared to that of a metal probe, and appeared to enable the brain to heal faster. The...

Engineers at Case Western Reserve University have made an electrochemical cell that uses a plasma for an electrode, instead of solid pieces of metal. The technology may open new pathways for battery and fuel cell design and manufacturing, making hydrogen fuel and synthesizing nanomaterials and polymers. A description of the research is now published in the online edition of the Journal of the American Chemical Society at http://pubs.acs.org/doi/abs/10.1021/ja207547b. "Plasmas formed...

Adaptation to upright walking leaves humans susceptible, Case Western Reserve University study shows Osteoporosis is blamed for backbone fractures. The real culprit could well be our own vertebrae, which evolved to absorb the pounding of upright walking, researchers at Case Western Reserve University say. Compared to apes, humans have larger, more porous vertebrae encased in a much thinner shell of bone. The design works well until men and women age and suffer bone loss, leaving them...

African-American women develop functional health challenges earlier than their fellow seniors, researchers say While examining self-reported data about the lives of 8,700 older people, a Case Western Reserve University sociologist identified an accelerated rate of reported physical limitations by African American women in their mid-50s and 60s. The finding surfaced as researchers looked generally at how the intersection of gender and race/ethnicity affect health disparities among older...

Fish Become More Aggressive In Reduced Environments

  An angry glare from the family goldfish might not be the result of a missed meal, but a too-humble abode. Fish in a cramped, barren space turn mean, a study from Case Western Reserve University has found. Ornamental fishes across the U.S. might be at risk, all 182.9 million of them. "The welfare of aquarium fishes may not seem important, but with that many of them in captivity, they become a big deal," said Ronald Oldfield, an instructor of biology at Case Western Reserve. Why,...
