[SAINS] New Clues to the Cause of Alzheimer’s Disease

ScienceDaily (July 1, 2011) — Researchers at the Sahlgrenska Academy, University of Gothenburg, have identified a series of novel proteins in human cerebrospinal fluid. The proteins, which carry specific sugar molecules, are found in greater concentrations in patients with dementia caused by Alzheimer's disease than in patients with dementia caused by other diseases. This gives hope for new forms of treatment in the future.

Göran Larson is a professor at the Sahlgrenska Academy and one of the authors of the article published in the revered journal Proceedings of the National Academy of Sciences (PNAS).
"When it comes to the link to Alzheimer's, we're thinking first and foremost of the possibilities to use these molecules as markers for an early and reliable diagnosis, but also, of course, of what role these molecules may play in the development and course of the disease."
These new molecules give researchers another way of thinking of the mechanisms behind Alzheimer's disease. Larson and his research team are already working with other researchers at the Sahlgrenska Academy and Chalmers University of Technology to develop new analytical techniques for measuring the concentrations of these molecules in cerebrospinal fluid. The aim is to try to make the analyses more sensitive, as well as simpler, cheaper and more accessible so that they can be used as routine clinical assays when investigating dementia.
"Dementia is a major and growing problem not just for healthcare but for society as a whole since more people are getting older and older, and the single largest risk factor for Alzheimer's is just that -- old age," says Larson. "There isn't currently any effective pharmaceutical treatment for Alzheimer's, but if this discovery can contribute to an early diagnosis then medicines that slow the progression of the disease can be tried before the dementia gets too severe.
"If we can link the formation of these molecules to the disease mechanisms behind Alzheimer's, then there's hope that we can also develop new drugs that can affect the course of this serious disease."
Alzheimer's Disease
With more than 100,000 people affected in Sweden, Alzheimer's is one of the most common diseases of our society. Caused by changes in the brain tissue, the disease predominantly affects the memory and often leads to an earlier death. Alzheimer's disease results in not only considerable suffering for patients and their families, but also in huge costs to society.

Nampaknya dah ada clues atau petanda baru yang menyebabkan nyanyok atau dementia ni...yg selalunya berpunca daripada penyakit Alzheimer's.


Apa2pun, penyakit nyanyok ni semua orang yang bernafas akan melalui proses penuaan. Cuma, tanda2 dia mungkin berbeza.
Maka, tanda2 orang yg menghidapi Alzheimer's berlalu dengan berbuahkan sel2 dan tisu2 dalam otak seseorang individu tu.

Thirty-seven strawberries a day may keep the doctor away

An apple a day has been replaced with strawberries -- 37 of them, to be exact. A recent study from scientists at the Salk Institute for Biological Studies in San Diego, California, suggests that eating a heaping bowl of the flavonoid-packed fruits every day can keep diabetes, Alzheimer's disease, and even cancer at bay.

Published on June 27 in the peer-reviewed journal PLoS ONE, the research reveals that a naturally occurring flavonoid called fisetin (also found in lesser degrees in other fruits and veggies) is found most abundantly in strawberries and packs a mighty punch at fending off diseases.

In the study, researchers fed Akita mice the equivalent of 37 strawberries a day for a human. The mice, genetically afflicted with high blood sugar, showed a reduction in medical diabetes symptoms and inflammatory activity linked to cancer, and the study also concluded that the fisetin-rich diet protected neurons in the brain to help prevent Alzheimer's disease.

Earlier research supports the findings that strawberries preserve brain function by reducing the cell-damaging inflammation and oxidation that accompanies age-related diseases. Scientists from the Chicago Healthy Aging Project revealed that older adults who consume strawberries at least once a month have less cognitive decline, and that women who consumed more than one serving of strawberries a month had a 16.2 percent slower rate of mental decline than those who consumed less.

ada dgr org2 tua kata utuk mengurangkan risiko nyanyuk adalah ngan membaca al-quran..

prove: tok wan (nenek) aku masih lagi segar ingatannya di kala usianya menjengah 90 tahun ats sebab membaca al-quran hari2... tak de tanda2 nyanyuk, cuma badan je bongkok sebab kesan osteoporosis

daus...

kajian2 ni mengikut kajian sains je.

dari sudut yg lain.....of course la kita akan pandang sudut Islam pulak.

hmmm....

sains ni hanya untuk 'membuktikan' fakta yang mereka nampak dengan mata kasar.

walhal, teori2 sains semua dah ada dalam al-Quran dan as-Sunnah (hadith Nabi s.a.w).

still, masih ada golongan yang sukar untuk nampak/yakin tentang kebenaran yang termaktub dalam al-Quran dan as-Sunnah.

p/s: arwah moyang aku hidup sampai umur 96 tahun. baru meninggal 2-3 tahun lepas. sepanjang hidupnya, aku tak nafikan beliau ada ingatan dan memori yang kuat. mana tak nya hari2 baca al-Quran. yang kagumnya....beliau masih ingat aku dan sepupu sepapat, cucu cicit... yang aku rasa boleh bilang dengan jari dalam setahun balik jumpa dia.

ooo penyakit nie penyakit nyanyuk......mungkin makan semut banyak sangat kot
