Create portable artificial kidney

People with renal failure and need blood purification through hemodialysis, in the near future will be able to obtain the freedom of movement. The U.S. company Xcorporeal Inc. has developed a portable "artificial kidney", held successful preliminary tests on humans, the journal Lancet.

Currently, hospital patients to connect to stationary vehicles "artificial kidney": as a result, they are riveted to bed at 4-12 hours 2-3 times a week. New apparatus for hemodialysis is portable - although fairly cumbersome - a device with a battery food, and up to 4-8 hours of continuous work.

The head of research Andrew Davenport (Andrew Davenport) and his colleagues from University College London (University College London) experienced portable "artificial kidney" at 8 patients, whose average age was 52 years. All participants in the study procedures required in regular haemodialysis.

In the tests came from two patients thrombosis, caused by insufficient protivosvertyvayuschey therapy; another patient was briefly disconnected from the apparatus because of a shift needles. Nonetheless, scientists have recognized tests successful, and the members unanimously agreed to recommend such treatment to other patients with renal insufficiency.

According to scientists, the procedure for cleaning blood in a portable "artificial kidney" occurs several slower than in a stationary apparatus. However, this does not represent the special problems, since the device can be easily be for a long time. Currently, the creators of portable "artificial kidney" trying to increase the duration of the apparatus, making 24 - of watch regime of its operation.

Nearly 1.3 million people worldwide suffer from chronic renal failure and need for regular dialysis. Only a few lucky ones, to await a suitable donor organ, conducting kidney transplant. Today's portable "artificial kidney" probably will be the first step towards a more convenient and portable miniature (and possibly ACG) hemodialysis machines, scientists believe.

Most muscle mass increases blood pressure? Hypertension, or high blood pressure - the main risk factor serdechnososudistyh diseases and the first risk factor paralysis. Hypertension is often linked to over weight, obesity and, therefore, also considered a serious risk factor. And what about muscle? Some competing bodibildery go on stage in the weight almost 150 kg, while their growth rarely reaches 180 cm Of course, they have to be a problem with pressure.

However, according to recent studies, it is not. In one experiment, scientists monitored the effects of stress on high blood pressure from 127 young men with dark skin and bright. U subjects has been measured dry weight, fat mass and overall percentage of fat in the body. Stress procedure consisted of two hours of rest, then the tense hours of video games and two hours of recovery. Samples of blood and uriny taken every hour, and blood pressure measured at intervals of 15 minutes. The main result of the experiment was that more muscle to ensure better regulation of blood pressure under stress. For high percentage of fat picture was quite different - it was more than fat in the body, the worse it regulate the pressure in response to stress impact. All this was related to sodium.

The results of this study are also relevant to Bodybuilding. Possession of a large muscle mass improves the body's ability to remove sodium and reduces the likelihood of delays in body fluids. The process can be accelerated if taking nutrients that promote the withdrawal of sodium, for example, potassium and magnesium. Magnesium acts as a natural inhibitor converts angiotensin-enzyme, preventing a persistent increase in blood pressure.

After a quarrel with her husband takes time not only to protracted emotional wounds. Physical wounds heal too slowly after that. Scientists found that half quarrel with the favourite is likely to hamper the ability of the body to regenerate at least for one day. U pairs, where there are constantly hostile relations, the time needed for healing, doubles.

Accordingly, the hospitals can conduct psychological tests for patients awaiting surgery to learn in advance how long they will need bed rest, scientists say. The key elements of the immune system are cytokines that promote healing of wounds. But if their levels in the blood is too high, they can cause inflammation associated with conditions such as heart attack, arthritis, diabetes, cancer, researchers say.

These findings come after scientists study 42 couples living in married an average of 12 years. It is important that people be psychologically prepared for an operation. Hospitals must ensure that reduce stress before the operation.

These drugs, clean the blood of harmful substances, until the liver is treated. Also nominated drugs, contributing to the restoration of the liver - essentsiale, gepabene, karsil, tsitrargenin, ursofalk, gepatofalk. Nominating and sorbents - enterosgel, polyphepane. There shall be a special meal - kislomolochnye products, fruits, boiled fish. Alcohol is forbidden, bold and acute food.
