Washington - If both your parents have Alzheimer's disease, you probably are more much likely than other people to get it, researchers said on Monday.
Their study focused on 111 families in which both parents were diagnosed with Alzheimer's disease, the most common form of dementia among the elderly, and assessed the risk for developing it among the offspring.

Take a group of patients recovering from serious operations. They need morphine to dull their pain and some need diazepam to calm their nerves. They will get their medication by intravenous drip, but won't always be told when they will get it - it might just be pumped in automatically.
The Italian researchers who conducted this ingenious study five years ago found that not being told they were receiving morphine cut the effect of the pain relief on the patients in half. And only those who were told they were getting tranquillisers became calmer; those who received diazepam without being told got no relief whatsoever.
PARIS: The MO1 beginner mobile phone is not as cuddly as a teddy bear, but manufacturers of the curvy, crimson and blue cellphone for 6-year-olds promise a similarly warm and fuzzy relationship. They boast about socialization, emotional health and the comforts of "peace of mind."
But the shiny child-size phones are stirring some parental and government unease, particularly at a time when the mobile telephone industry is reaching deeper into saturated markets to tap customers with chubby hands capable of cradling both dolls and phones.
Case Western Reserve University School of Medicine researchers published a study identifying the hereditary components of colorectal cancer (CRC.) It is the first large linkage study of families with CRC and colon polyps in the country.
Because only five percent of CRC cases are due to known gene defects, this study is designed to identify the remaining CRC-related susceptibility genes. The team built on a previous study which identified a specific region on chromosome 9q that harbors a CRC susceptibility gene. Upon review of a whole genome scan of all chromosome pairs in 194 families, the researchers were able to identify additional CRC gene regions on chromosomes 1p, 15q, and 17p.
A team of Penn State University researchers is the first to demonstrate that lipid molecules in cell membranes participate in mammals' reactions to allergens in a living cell. The finding will help scientists better understand how allergy symptoms are triggered, and could contribute to the creation of improved drugs to treat them. The work will be reported in the 14 March issue of the Journal of Biological Chemistry.
Washington - Study after study has failed to show any link between vaccines and autism, but many parents of autistic children remain unconvinced. For the skeptics, the case of 9-year-old Hannah Poling shows that they have been right along.
