A new study, conducted by the American Heart Association, suggests that people with depression are at higher risk for a common heart arrhythmia.
During the study, a team of scientists found that those patients who were on antidepressants or scored in the highest category for depression symptoms were at 30% higher risk of atrial fibrillation.
Lead study author Dr. Parveen Garg explains: “Our findings identify a large portion of Americans who may be at an increased risk for developing atrial fibrillation. Clinicians and patients should be aware that depression has been shown in several studies to be a risk factor for heart disease in general and, in this study, for atrial fibrillation as well.”
Scientists from the University of South Florida in Tampa, USA, suggest that using betanin, a compound that gives dark red color to beetroots, can be used in future drugs to treat the Alzheimer’s disease.
To achieve their results, the team of researchers conducted a series of laboratoryexperiments during which they monitored the activity of amyloid beta in different context with the help of 3,5-Di-tert-butylcatechol (DTBC), a compound that allows the scientists to observe the process of oxidation.
Li-June Ming, one of the lead researchers of the study, says: “This is just a first step, but we hope that our findings will encourage other scientists to look for structures similar to betanin that could be used to synthesize drugs that could make life a bit easier for those who suffer from this disease.”
Physical activity can not exclude all negative consequences caused by alcohol consumption, however, doing sports helps to reduce the risk of many diseases caused by excessive consumption of alcoholic beverages.
This conclusion was made by British specialists, and they believe that physical activity significantly reduces the risk of development of cancer and cardiovascular diseases due to alcohol abuse. According to experts, they carefully studied all the archival data for the period from 1994 to 2006 for Scotland and England. It turned out that people who abuse alcohol are more likely than others to develop many diseases, but this is provided if they have a sedentary lifestyle.
Scientists have found that people who have a sober lifestyle are the least likely to die prematurely, but those who exceed the weekly alcohol limit by several units, but regularly do sports are also included in this group. Experts stressed that people who drink two or four times a week can exclude themselves from the risk group if they devote lessons in the gym or jogging about two to three hours a week.
Approximately 80% of the male population of the entire planet experiences constant pain in the back. The reason for this are not correct posture formed in childhood and the lack of constant exercises, without which the muscles simply do not have enough strength to support the body. Fortunately, the problem can be solved without medication. It will be enough to work regularly in the gym. However, not all exercises will affect the sick back in a fertile way. There are five best workouts that will not only strengthen the muscles, but also help get rid of the old problem.
Pulling up with a wide grip. You will not manage to get rid of back pain without pull-ups. This exercise involves the widest muscles of the back – this training help to become slimmer even to those who could not defeat bad posture from childhood. The main thing is to remember: repetition is done slowly, with control at all stages; the right grip is slightly wider than the shoulders.
Pull-down. The bonus of this exercise is an increased growth of muscle mass. Pull-downs make the whole body work: the legs stabilize the body, and the hands are busy with a specific load. Do the exercise with full efficiency, otherwise it will lose half of its usefulness. Capture – on the width of the shoulders, the movement down does not involve the body, pulling is carried out from the activities of the shoulders back and down. Do not forget to take a short pause at the end point.
Dead-lift. It is very important to perform the dead lifting correctly. Jerks, wrong setting of feet, haste – the easiest way to get a serious back injury. But if you do everything right, the dead lift will turn into the best exercise for the whole body. Maintain a natural deflection in the lower back. Capture – on the width of the shoulders. Pull the body up, while pushing the hips slightly forward. The end point is a short pause and a smooth return of the rod to its starting position.
Dead lift in slope. The static version of the dead lift is less traumatic and more accentuated on the muscles of the back. Starting position: the body is bent almost parallel to the floor. Capture – is slightly wider than the shoulders, straight. Raise the barbell, straining the lateral and middle muscles.
Rowing on the simulator. Sit down on the bench of the cable simulator. Capture is usual, slightly wider than shoulders. Pull the crossbar to the top of the abdomen. Returning to the starting position, slightly bend forward – so you will give the muscles a stimulating stretching.
Numerous studies conducted earlier showed that regular exercises have a positive effect on physical and mental health. The new work of American scientists confirms this. They believe that running five kilometers once a day is useful for the hippocampus (the brain center of memory).
Memorization of information proceeds optimally if the connections between neurons of the hippocampus are gradually amplified. This process is called long-term potentiation (LTP). The researchers noted: chronic stress weakens contacts between nerve cells and reduces LTP, which affects memory.
Specialists from the University of Brigham Young placed one group of mice in cages with wheels for running. The rodents ran about 5 kilometers a day. The experiment lasted 4 weeks. Another group of mice received no physical activity. After running, 50% of each group was stressed. Rodents were placed in cold water or put on a high platform. An hour later, all animals were measured with an LTP level. It turned out that the running mice had better memory than the control group.
