What causes stomach ulcers?

About 10-12 percent of people in Europe and America suffer from stomach or intestinal ulcers at some time in their lives. What is an ulcer and what causes it?

The digestive juice produced in the stomach contains hydrochloric acid, mucus, and an enzyme called pepsin. Pepsin breaks down the protein in food into simpler substances. But sometimes a mixture of pepsin and acid can affect the walls of the digestive tract, resulting in ulcers. They usually occur on the walls of the stomach. Usually, people who develop such ulcers in the stomach or intestines have a concentration of hydrochloric acid above the normal level.

There are other reasons that ulcers appear or the process of treating an already formed ulcer is difficult. So, nervous, ambitious people are much more prone to peptic ulcer disease than calm people. Smoking also makes ulcers worse or harder to treat. Rough food is also not conducive to healing. But in general, this disease can appear in anyone at any age (although very rarely before the age of ten years).

Men get sick four times more often than women. How do you know if you have an ulcer? Pain will tell you! Pain may appear 30-60 minutes after eating. Such pains rarely occur in the morning, but usually they appear after lunch and dinner. They can also start at night, after midnight.

Stomach pain usually comes from eating. When a person has a peptic ulcer, the doctor recommends a diet consisting of soft foods with a lot of dairy products, and advises him to get plenty of rest, not to be nervous, and to avoid various fears.

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 ... >>

Attoclocks capable of measuring the time parameters of the movement of electrons 12.05.2018

Everything that happens at the atomic and molecular levels happens so fast that it cannot be felt by any human senses. For example, a tiny electron, in order to move from one atom to another during a chemical reaction, takes only a few hundred attoseconds. What is an attosecond? Take a second and divide it into a billion parts, and then divide one part into another billion smaller parts. An attosecond is 1*10^-18 seconds.

But, in order to understand what is happening in the invisible "universe" of quantum events, people need to be able to measure time intervals on an attosecond scale. And this is what new "atto-clocks" created by researchers from the SLAC Linear Accelerator Laboratory at Stanford University are capable of. The new clock is based on an X-ray laser capable of generating pulses of several tens of attoseconds, which was previously used to capture video of events occurring at the molecular level.

However, capturing events related to quantum physics is fundamentally different from capturing events from the field of classical physics and chemistry. Previously, scientists lacked the ability not only to measure, but also to control the power of X-ray pulses. And too powerful pulses affected the fragile quantum state and the behavior of particles, which made it impossible to correctly interpret the data obtained.

The principles of atto-clock design were proposed by Swiss physicists about a decade ago. But only now the possibility of creating such a device, which is based on some equipment already available to the specialists of the SLAC laboratory, has begun to appear. The device has a diameter of 0.6 meters and is located inside a small vacuum chamber. The structure of the atto-clock includes 16 cylindrical sensors installed like spokes in a wheel.

The "heart" of an atto-clock is an atom or a molecule, which is also an object of research at the same time. This object is placed in the center of the circle formed by the sensors, and X-ray pulses are applied to it. The atom(s) is ionized and loses some of their electrons, which, under the influence of the electric field of the laser light, are directed towards the sensors and captured by one of them. "Catching" a free electron, scientists can calculate the exact value of the energy contained in the X-ray pulse, and the exact time of impact of this pulse on the object under study.
