Countries with more wealth, better hygiene have higher Alzheimer’s risk

People living in wealthier countries with better access to clean water and good hygiene may have a higher risk of developing Alzheimer’s disease, Medical News Today reported.
In a study published in the journal Evolution, Medicine and Public Health, researchers analyzed data from the World Health Organization's (WHO) Global Burden of Disease (GBD) report in 2009.
They noted that countries with better access to clean drinking water, lower rates of infectious disease and a greater percentage of the population residing in urban areas all had higher rates of Alzheimer’s disease, according to Medical News Today.
Researchers explained their findings using the ‘hygiene hypothesis,’ which suggests that people who live in places with access to better hygiene have less exposure to certain germs. With no harmful bacteria to fight, people’s immune system’s develop insufficiently, putting them at a higher risk for autoimmune diseases like dementia and Alzheimer’s.
“The 'hygiene hypothesis,' which suggests a relationship between cleaner environments and a higher risk of certain allergies and autoimmune diseases, is well-established,” lead study author Dr. Molly Fox, from the University of Cambridge, said. “We believe we can now add Alzheimer's to this list of diseases."
Currently, more than 50 percent of people with Alzheimer's live in the developing world, and by 2025, this figure is expected to rise to more than 70 percent, according to Fox.
“An awareness of this by-product of increasing wealth and development could encourage the innovation of new strategies to protect vulnerable populations from Alzheimer's,"

Exercise Helps Prevent Kidney Stone Risk

In older women, exercise was found to cut kidney stone formation, find researchers.

The study noted that even walking for a couple hours a week could cut the risk of developing this painful and common problem by about one-third, the New York Daily News reported.

Dr. Mathew Sorensen of the University of Washington School of Medicine in Seattle, who led the study, said that just getting a minimum amount of exercise could help.

The study was discussed Friday at an American Urological Association conference in San Diego.

Kidney stone problem is a little more common in men. But incidence has risen 70 percent over the last 15 years, most rapidly among women.

Obesity raises the risk, as do calcium supplements, which many women take after menopause. A government task force has recently advised against supplements for healthy older women, saying that relatively low-dose calcium pills don't do much to keep bones strong but make kidney stones more likely.

The new research involved nearly 85,000 women 50 and older in the government-funded Women's Health Initiative study.

Participants said how much exercise they usually got and that was translated into "METs" - a measure of how much effort an activity takes.

After about eight years, 3 percent of the women had developed a kidney stone. Compared to women who got no leisure-time exercise, those who got up to 5 METs per week had a 16 percent lower risk for stones.

The risk was 22 percent lower with 5 to 10 METs per week and 31 percent lower for 10 METs or more. Exercise beyond 10 METs added no additional benefit for kidney stone prevention. Exercise intensity didn't matter - just how much women got each week.

The researchers explained that exercise changes the way the body handles nutrients and fluids that affect stone formation.

Exercisers also sweat out salt and tend to retain calcium in their bones, rather than having these go into the kidneys and urine where stones form, they said.

They also tend to drink water and fluids afterwards, another plus for preventing stones.

Exercise is also known to cut the risk of heart disease, diabetes, high blood pressure and other conditions that raise the risk of kidney stones.

Next, researchers aim to study men and younger women to see if exercise helps prevent kidney stones in them, too.

Night work for women affects their health negatively

Studies have proven is published by professional societies in research on tumor link a woman's tumors night work or disorder, which affects their working hours in the disruption of daily systems administrator in turn punish cases of vigilance and sleep and control the number of biological functions of the body.

There are many theories that linked between tumors and the above factors, including the exposure to night-light limits the secretion night of the hormone melatonin (the hormone secreted by the pineal gland in the brain), which represents a factor of anti-tumor, disorder genes of the biological clock that controls the reproductive cell and the sleep disorders weaken the immune system.

Underwent up to 3000 a French woman of the study and reached the proportion of women working at night to 11% and proved to increase the proportion of injury these women's tumors by 30% in comparison with other workers in the times of the day, and apply this percentage to women working at night for more than four years or for women who are missing systems work weekly for 3 nights per week, which increases the frequency disturbance between systems day and night.

The lack of differentiation of mammary cells completely before the first pregnancy for women working at night before her pregnancy confirmation of the link between night work and increase the chance of breast cancer.

Chemicals that affect the biological clock may help in the treatment of diabetes

Researchers have discovered biologists at the University of San Diego chemicals offer new ways and promising for the development of pharmaceutical drugs for the treatment of metabolic disorders Kalnmt II diabetes, and considered the results of previous research to snap to focus on the chemicals do not cause and directly control the production of glucose in the liver but also affect the activity of protein main (Krebtokrom) that controls the internal mechanisms of the activities of daily day and night (circadian).

I suppose many scientists link the biological clock disorder injury and excessive obesity, diabetes, where the injured rat experiments with both disorders as a result of altered biological clock.

Was developed chemical former, which take the form of small molecules to pharmaceutical drugs control the timer mechanisms of protein Krebtokrom and thus suppress the production of glucose in the liver, where he developed the human mechanisms of chemical vital to ensure the continuous supply of glucose and flowing to the brain at night and the absence of food intake or exercise of any activity, where indicate human hormones in late stages of the night to fasting status, and by daylight and the start of his rights to close the clock signals associated with fasting and stimulates the liver to produce more glucose.

Link between researchers in their study of the physiological effect of protein Alkrebtokrom and organized for the timing of the procedure for the periodic patterns of eating any time the status of fasting and night eating during the day and thus determine the rate constant of production of glucose in the bloodstream.

5 foods to beat the summer heat

Some foods that help you to overcome the summer heat:

• Option: Option to keep cold, because it contains a great extent on the water, so the eating one piece similar to drinking a soft drink. It also has the option of ascorbic acid and acid Alcavic compounds help reduce the swelling and sweating caused by the high heat and humidity.

• Peppermint: It is known that the mint leaves give a sense of cold and are used in moderate tea and ointments and painkillers. At higher temperature, the smell of mint provides recovery and vitality.

• Watermelon: Contains the water by 90%, plus it contains many nutrients including vitamin A and C and lycopene, an antioxidant. Watermelon is also full of Pkhrlja sodium and potassium, which the body loses through sweating, which makes it the best sports drink normally.

• Grapefruit: Citrus fruits contain a lot of water and taken up in this van provides quick recovery from high temperature. Grapefruit in particular, contains a little sodium and full of fat burning enzymes.

• Lettuce: There are several species of which vary Lkhos taste and installed, Kalargeola known Balruka which has a pungent taste of sour is used in sauces. There is also a kind Almsklon, which contains a mixture of papers Alkhdhare sweet and hot.
