Tourist tips

Solar and heat stroke accompanied by a weakening of the pulse and breathing, redness of the skin, loss of consciousness.

Unload the victim, put him in the shade, pour water on his head, fan. Attach a bottle of hot water to your feet (rounded stones heated in a fire).

Treat skin burns (solar or from a flame) with a 5% solution of tannin or potassium permanganate, which causes a protective crust to form on the wound.

In complicated cases, apply a sterile dressing.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Opioid pain reliever without side effects 07.03.2017

Opioid drugs act as a powerful pain reliever, but have a number of side effects and can be addictive. But now this problem has been solved: German scientists have created a drug that effectively copes with pain and does not have a negative effect on the patient at all.

Opiate-based drugs have many disadvantages. They often bring the patient both minor discomfort, such as intestinal obstruction, and serious life-threatening, such as respiratory distress syndrome. But modern medicine cannot refuse opiates: they cope with pain extremely effectively. Unfortunately, until now, scientists have not been able to make opioid drugs bring only one benefit.

But that problem is in the past. Researchers have developed a new type of opioid that selectively targets only inflamed tissues. Theoretically, such a drug will not only relieve pain, but also will not cause side effects and addiction. The invention has already been tested on rats, and the result was purely positive, so that in the near future a new drug can become a real panacea for various types of pain.

Opioids act on special receptors located throughout the human body. The molecules of the substance are compatible with them like a key with a lock, and when they interact, dopamine is released into the blood, which suppresses pain. This is great for inflamed areas, but for healthy tissue, the benefit is highly questionable. When opioids attach to receptors in the brain, they can interact with the nerves that control a person's breathing rate, slowing them down to dangerously low levels. In the gastrointestinal tract, opioids can also negatively affect the nervous system, causing intestinal obstruction (in other words, constipation). In addition to all of the above, the release of doraphin causes euphoria and relaxation, which in the future can, with a high probability, provoke dependence on drugs.

But what if we create a painkiller that selectively interacts with opioid receptors only in damaged tissues? To find out, the research team first looked at what distinguishes inflamed tissue from healthy tissue in terms of acidity. It turned out that the acidity of damaged areas is much higher than that of healthy ones, which means that the matter was small: opioids were obtained in the laboratory that bind to receptors only under conditions of increased acidity.

Christoph Stein, professor at the Department of Anesthesiology and Intensive Care at the Free University of Berlin and co-author of the article, says that such measures eliminate the risk of side effects and addiction - opioids simply do not bind to receptors either in the gastrointestinal tract or in the brain. The results of his team's study were published today in the journal Science. The new drug is called NFEPP, and it was tested in rats with a positive result: rodents stopped feeling pain without any respiratory or stomach discomfort. Even after several rats were kept on opioids for a long time, after the dose was abruptly stopped, they did not react to this fact, although usually opioid dependence develops in rats in much the same way as in humans. As for effectiveness, the new drug and the old, long-proven in practice remedy "fentanyl" turned out to be equally effective.

The next step, according to Stein, will be testing the drug in humans. Unfortunately, bureaucratic red tape comes into play here, so scientists will be lucky if they receive all the necessary permits within at least the next few months. If their work is successful, it could be a real revolution in the field of pain medication.
