Bexarotene cancer drug may reverse Alzheimer’s symptoms

Drug quickly reverses Alzheimer’s symptoms in mice — Case Western Reserve researchers discover FDA-approved drug rapidly clears amyloid from the brain and reverses cognitive defects – Neuroscientists at Case Western Reserve University School of Medicine have made a dramatic breakthrough in their efforts to find a cure for Alzheimer’s disease. The research shows that use of a drug in mice appears to quickly reverse the pathological, cognitive and memory deficits caused by the onset of Alzheimer’s.

Additional breast surgery common after partial mastectomy

Study finds substantial variability in rate of additional surgery after partial mastectomy – Nearly one in four women who undergo a partial mastectomy for treatment of breast cancer have another surgery to remove additional tissue (reexcision), and there is substantial surgeon and institutional variation in the rate of reexcisions that cannot be explained by patients’ clinical characteristics.

Brain stimulating habits lowers Alzheimer’s disease risk

Lifelong brain-stimulating habits linked to lower Alzheimer’s protein levels – Individuals who keep their brains active throughout life with cognitively stimulating activities such as reading, writing and playing games appear to have reduced levels of the ?-amyloid protein, which is the major part of the amyloid plaque in Alzheimer disease.

Children with ADHD may have functional brain pathways disrupted

Functional brain pathways disrupted in children with ADHD – Some abnormalities in the brains of children with attention deficit/hyperactivity disorder (ADHD) may serve as a biomarker for the disorder, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

New urine test can detect prostate cancer risk early

Urine test shows prostate cancer risk, U-M study finds — Test for gene fusion can assist in the early detection of prostate cancer – A new urine test can help aid early detection of and treatment decisions about prostate cancer. Examining the urine sample for TMPRSS2:ERG and PCA3 and stratified patient into low, intermediate and high score, indicating their risk of cancer can help.

Parkinson’s disease risk for people exposed to pesticides near workplace

High risk of Parkinson’s disease for people exposed to pesticides near workplace — Study first to implicate pesticide ziram as possible cause for disease – In April 2009, researchers at UCLA announced they had discovered a link between Parkinson’s disease and two chemicals commonly sprayed on crops to fight pests. That epidemiological study didn’t examine farmers who constantly work with pesticides but people who simply lived near where farm fields were sprayed with the fungicide maneb and the herbicide paraquat.

Autism changes molecular structure of brain

Autism changes molecular structure of the brain, UCLA study finds — Discovery points to a common cause for multifaceted disease – A new UCLA study is the first to reveal how the autism disorder makes its mark at the molecular level, resulting in an autistic brain that differs dramatically in structure from a healthy one.

Breast implants linked to ALCL a rare cancer

FDA review indicates possible association between breast implants and a rare cancer — Agency requesting health care professionals to report confirmed cases – Saline and silicone gel-filled breast implants are linked to anaplastic large cell lymphoma (ALCL), a very rare type of cancer, announced by US Health Agency FDA.

Imaging can identify biomarker of alzheimer’s disease

Imaging Procedure Can Identify Biomarker Associated With Alzheimer Disease – Preliminary research suggests that use of a type of molecular imaging procedure may have the ability to detect the presence of beta-amyloid in the brains of individuals during life, a biomarker that is identified during autopsy to confirm a diagnosis of Alzheimer disease.
