New blood test to assess aging or predictable dementia

Release date: 2015-09-09

Scientists have invented a blood test that assesses the rate at which a person ages. They believe that this can also be used to predict the risk of Alzheimer's disease and to analyze the "youngness" of transplanted organs.

According to the British "Independent" website reported on September 7, this method detects the vitality of specific genes. Researchers believe that these genes are an accurate indicator of a person's "biological age," and that a person's biological age may be greater or less than their actual age.

Scientists say the study shows that the test distinguishes between healthy people and Alzheimer's patients, so it may be useful to detect early-stage Alzheimer's patients who have not yet developed symptoms.

James Timmons, professor of precision medicine at King’s College London, said the “aging test” could also be used to analyze the biological age of organs used for transplantation to predict the availability of organs after they were transplanted to others.

Timmons said: "There is a significant difference between people with mild cognitive impairment and healthy people, so a test can be developed accordingly, especially in combination with relevant clinical variables. And this is the most promising As a way to find 'at risk' people to guide them to preventive clinical trials."

Timmons said that this can also be used to identify older people with biological ages, so that once they accidentally die, their organs can be considered for transplantation to others.

A research paper published in the British journal Genomics Biology analyzes the vitality of a group of key genes in a 65-year-old healthy elderly who are tested for ribonucleic acid (RNA) levels in the blood of the subject.

Scientists have gene activity as a marker of biological age. They then studied the RNA of 70-year-old healthy older adults and analyzed their health records over the past 20 years. It was found that during the 12-year study period, higher gene activity scores were consistent with better cognitive health and renal function, both of which were indicators of the risk of premature death.

An important finding of the study was that the activity of this gene was the same in the brain and blood of Alzheimer's patients. In this way, scientists can quickly and easily diagnose the brain by blood samples.

hydroponics system-nutrient technique (NFT)
NFT does not give average support to roots. Typically, the roots sit in a long sloping channel irrigation (Fig. 1.1). The nutrient is introduced into the high class of the canal and allowed to flow over the roots after which it drains into the nutrient tank. This is then re-pumped back into the channel to repeat the watering process.
This feed cycle can be intermittent or continuous. An & lsquo; The intermittent 'rss cycle is controlled by the clock and repeated several times per hour. this is sometimes called the "NFT pulse". The NFT pulse usually achieves better aeration of the roots as the roots are exposed to air between each feed. A & lsquo; continuous' rss cycle works non-stop. This is often used in commercial operations.


You can easily grow your favorite flowers at home without muddy mess and need to water your plants regularly.

Hydroponics is an ideal way to grow plants in urban areas. This makes it a great hobby that helps you to relax and it is fun to watch the hydroponic plants grow in the garden nft.
