What are hormones for?

Hormones are called biologically active substances secreted by the endocrine glands or clusters of specialized cells of the body and have a targeted effect on other organs and tissues.

Under the control of hormones, all stages of the development of the body from the moment of its inception to old age, all the main processes of life. By selectively controlling almost all types of cellular metabolism, hormones determine the normal course of growth of tissues and the whole organism as a whole, gene activity, sex formation and reproduction, adaptation to changing environmental conditions and maintaining the constancy of the internal environment of the body, behavior.

The influence of hormones on the metabolism in the body is carried out mainly by regulating the activity of enzymes. Each hormone affects the body in complex interactions with other hormones; in general, the hormonal system, together with the nervous system, ensures the activity of the body as a whole.

The chemical nature of hormones is different - proteins, peptides, amino acid derivatives, steroids. Hormones used in medicine are obtained by chemical synthesis or isolated from the corresponding organs of animals.

Insufficient or excessive secretion of hormones in the body leads to endocrine diseases. The aging process, the development of cardiovascular, oncological and other diseases are largely associated with a violation of hormonal regulation.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Cloak of invisibility aligns magnetic fields 05.04.2012

European researchers from Slovakia and Spain have created a device that allows you to hide the static magnetic field of an object. The invention can be widely used in military affairs and medicine.

The device consists of a permanent magnet and a coil to which current is applied. The device consists of a two-layer hollow cylinder. The inner layer is made of a superconducting material that repels the magnetic field, while the outer layer is made of a ferromagnet that has its own magnetic field. When the device is placed in a magnetic field, it causes the magnetic lines of force to wrap around a hollow cylinder, masking whatever is inside. Thus, everything inside the cylinder is hidden from the magnetic detectors.

The device allows you to mask various objects, such as objects that distort the image of medical tomographs or scanners for security systems at airports. If, however, the cylinder is scaled up to the size of a light submarine hull, then it can be made invisible to magnetic detectors, which can be used to reliably detect even a submarine lying on the ground. In the military sphere, the new device can also be useful for protecting complex electronic equipment from interference and electromagnetic weapons.

In medicine, such a device is especially useful, since various implants, such as pacemakers, make it very difficult to scan with an magnetic resonance imaging scanner. In this regard, the masking cylinder is an ideal tool for protection against electromagnetic interference.

The new device is made from commercially available materials and can operate in strong magnetic fields and with common coolants like liquid nitrogen.
