Folic acid improves vascular function in amenorrhea runners

Sunday, May 30th, 2010

A study reveals that oral supplements of folic acid may be cheap and safe ways to improve vascular function in young women suffer who practice athletics and amenorrhea (no period). The work appears in the May issue of Clinical Journal of Sport Medicine.

Although the benefits of exercise are known, there are risks to health. The young athletes who do not have a diet sufficiently to offset the energy they expend can stop having periods or irregular periods. This results in profiles of estrogen similar to those of a postmenopausal woman, which poses a greater risk of developing heart disease early. The prevalence of amenorrhea is 44 percent among the 23 million young people in school who are at least six times a week in the U.S.

Anne Hoch, the University of Wisconsin (USA) analyzed the effect of folic acid supplements in the dilation of the brachial artery, the alteration is one of the signs that allows the early diagnosis of heart disease.

Hoch analyzed 20 athletes aged between 18 and 35 who did not take the pill and had run at least 20 miles per week (32.2 km) in the previous 12 months. At baseline, girls who had amenorrhea group had a reduced arterial dilation, similar to that of a postmenopausal woman. (more…)

First step to biological regeneration of a heart

Thursday, May 27th, 2010

biological regeneration of a heartThe technique is to use the matrix of an organ and tissue to grow from a stem cell seeding

The artificial heart of the future could be biological. It’s not a pun. It would, in a few years if the process works, the closest thing to create a heart. But do not start from scratch. The novelty of the technique, explains the head of cardiology at the hospital Gregorio Maranon de Madrid Francisco Fernandez-Aviles is that it uses a kind of mold. In this case, it ruled out a heart transplant.

The first step is to treat this body with an enzymatic detergent to eliminate the donor cells. The result is that the flesh is dissolved, and allowed to clean the matrix of the heart (which would be if we were talking skeleton of bone or connective tissue made up of infrastructure in this case). From there, the structure is grown stem cells to regenerate heart. This step is complicated, but since there is a history (it has done with trachea and small animals, says Fernandez Aviles). But there is one step: that the structure, properly irrigated, is made to beat. (more…)

Acid improves vascular function in amenorrhea runners

Monday, May 24th, 2010

A study reveals that oral supplements of folic acid may be a cheap and safe way to improve vascular function in young women who play athletics and suffer amenorrhea (no period). The work appears in the May issue of the Clinical Journal of Sport Medicine.

Although the benefits of exercise are known, there are risks to health. The young athletes who do not have enough dietary energy to compensate for spending may stop menstruating or have irregular periods. This results in profiles of estrogen similar to those of a postmenopausal woman, which leads to an increased risk of developing early heart disease. The prevalence of amenorrhea is 44 percent among the 23 million young people in school who are at least six times a week in the U.S.

Anne Hoch, the University of Wisconsin (USA) analyzed the effect of folic acid supplements in the dilation of the brachial artery, the alteration is one of the signs that allows the early diagnosis of heart disease.

Hoch analyzed 20 athletes aged between 18 and 35 who did not take the pill and had run at least 20 miles per week (32.2 km) in the previous 12 months. At baseline, girls who had amenorrhea group had a reduced arterial dilation, similar to that of a postmenopausal woman.

Both they and those who menstruated normally received 10 milligrams of folic acid daily for four weeks. Vascular function was normal in all women at the end of the study.

Working long hours is bad for the heart

Friday, May 21st, 2010

A study of 6,000 British civil servants found a 60% increase in the probability of coronary heart disease

Working 10 or more hours a day is bad for the heart, according to results of a study in the UK. People who usually work three or four hours over the seven rules are 60% more likely to suffer serious heart problems, including heart attacks than those who serve their time, researchers have said, based on a study conducted over 6,000 British civil servants over 11 years. Work an hour or two has not, however, adverse effects.

The relationship between work hours and heart disease is demonstrated in the study, but not the cause, which may be the stress of overwork. In general, people tend to take hours with a pattern A (these tend to be aggressive, competitive, tense, aware of the passage of time and usually hostile), or suffer psychological disorders manifested by depression and anxiety and may not get enough sleep or do not have time to relax before sleep, researchers say.
