Dementia-associated weight loss begins before the onset of the definite dementia symptoms and accelerates by the time of the diagnosis, according to a study in the January issue of Archives of Neurology, one of the JAMA/Archives journals.
Weight loss in old age is common and may be related to various diseases, according to background information in the article. "It has long been observed that weight loss is common in Alzheimer disease (AD), but this has been documented in people who already have dementia."
Robert Stewart, M.D., From the Institute of Psychiatry, London, and colleagues analyzed data from 1,890 men (aged 77-98 years) who were participants in The Honolulu-Asia Aging Study. This population-based study of Japanese American men included 112 men with incident [new onset] dementia and 1,778 without dementia. The study participants were examined on six occasions over a period of up to 34 years. Weight was measured at each examination and dementia was ascertained at the three most recent examinations.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
In the fight against cancer, scientists are developing new drugs to hit tumor cells at so far unused weak points. Such a “sore spot” is the protein complex...
