Brainy beverage: study reveals how green tea boosts brain cell production to aid memory | KurzweilAI

Brainy beverage: study reveals how green tea boosts brain cell production to aid memory | KurzweilAI | anti dogmanti | Scoop.it
Green tea leaves steeping in a gaiwan 盖碗 (credit: Wikimol/Wikimedia Commons) It has long been believed that drinking green tea is good for the memory.


Now Chinese researchers have discovered how the chemical properties of China’s favorite drink affect the generation of brain cells, providing benefits for memory and spatial learning.


The researchers, led by Professor Yun Bai from the Third Military Medical University, Chongqing, China, focused on the organic chemical EGCG (epigallocatechin-3 gallate), the major polyphenol in green tea.

EGCG can easily pass through the blood-brain barrier and reach the functional parts of the brain. While EGCG is a known antioxidant, the team believes it could also have a beneficial effect against age-related degenerative diseases.


Green tea increases neurogenesis

“We proposed that EGCG can improve cognitive function by impacting the generation of neuron cells, a process known as neurogenesis,” said Bai. “We focused our research on the hippocampus, the part of the brain that processes information from short-term to long-term memory.”


In humans, hippocampal neurogenesis declines with age, and this decline is involved in various neurological disorders, many of which are associated with cognitive deficits.


The team found that ECGC boosts the production of neural progenitor cells, which, like stem cells, can adapt, or differentiate, into various types of cells. The team then used laboratory mice to discover if this increased cell production gave an advantage to memory or spatial learning.

“We ran tests on two groups of mice, one which had imbibed ECGC and a control group,” said Bai. “First the mice were trained for three days to find a visible platform in their maze. Then they were trained for seven days to find a hidden platform.”


The team found that the ECGC treated mice required less time to find the hidden platform. Overall, the results revealed that EGCG enhances learning and memory by improving object recognition and spatial memory.


“We have shown that the organic chemical EGCG acts directly to increase the production of neural progenitor cells, in both in vitro tests and in mice,” concluded Bai. “This helps us to understand the potential for EGCG, and green tea which contains it, to help combat degenerative diseases and memory loss.”


“These findings warrant a general recommendation to consume green tea regularly for disease prevention and provide support that EGCG may have therapeutic uses for treating neurodegenerative disorders,” the researchers conclude.


Human epidemiological data show that green tea consumption is inversely correlated with the incidence of dementia, Alzheimer’s disease, and Parkinson’s disease.


The research is published as an open-access article in Molecular Nutrition & Food Research. It is part of a collection of articles bringing together high quality research on the theme of food science and technology with particular relevance to China.

UPDATE Sept. 9, 2012: Prof. Yun Bai responds to this question: “The paper mentions that ‘it is likely that a daily 1500–1600 mg bolus of EGCG in humans would achieve physiological levels.’ How many cups of tea does that correspond to?”


“I see someone said in the comments ‘it would take at least 50 cups.’ Of course, we need not to do so. First, I have to clarify the difference between green tea and coffee. Because when you have a cup of coffee, you must add new coffee and water to the second cup. But for green tea, the tea is always there, you only need to add water to make the effective components release. We know EGCG is about 10–15% the weight of green tea, so you need 10–15g [.4--.5 oz.] of green tea, and just add hot water, and the EGCG will be in the water.

“We plan to do some research on EGCG and disease, such as Alzheimer’s disease and diabetes, maybe from new target cells and molecules.”

Researchers, Startups Hope One Drop of Blood Could Diagnose All Types of Cancer

Researchers, Startups Hope One Drop of Blood Could Diagnose All Types of Cancer | anti dogmanti | Scoop.it

As genetics reveals the incredible diversity among cancer cells, researchers have largely given up pursuing a silver bullet to cure all types of cancer. Instead, many have begun searching for the next-best thing: a silver bullet test to diagnose all cancers. The test would look for markers of cancer in the patient’s blood, where the process of tumor-making leaves a trail that can often be picked up before tumors are big enough to spot.

 

And early diagnosis makes a big difference in survival rates. When cancer is found in Stage 0, as it’s just getting started, or in Stage 1, it kills only 10 percent of patients, regardless of what type of cancer it is, for the most part. Many of the cancers we know as the deadliest are so known because they are rarely found in earlier stages.

Using Thorium for Energy

Using Thorium for Energy

Liquid Fluoride Thorium Reactors LFTRs were invented 50 years ago by an American named Alvin Weinberg.

LFTRs are revolutionary liquid reactors that run not on uranium, but thorium. These work and have been built before.

The main reason this technology is not in widespread use today is our irrational fear of nuclear energy, despite the fact that more people have died from fossil fuels and even hydroelectric power than nuclear power.

That plus the multinational companies and governments invested in fossil fuel use such as oil, coal and gas.

How much Thorium for Energy do we Have?

Latest research says we have at least 2.6 million tonnes of it on earth, distributed over all the continents.

For every kilogram of thorium, LFTRs can produce 3.5 million Kwh of energy.

This is 70 times greater than uranium and 10,000 times greater than oil.
