Plastic waste is a concern that is growing due to its nondegradable nature. Many species of microorganisms naturally produce polyhydroxyalkanoates, macromolecule-polyesters that may be used to replace conventional plastics. A variety of microorganisms can completely biodegrade PHAs within a year, which is unlike petroleum-derived plastic that takes decades to degrade. Carbon dioxide and water are produced during this biodegradation, which is returned to the environment. Many methods of mass-prod

A prominent place among the hematological parameters is occupied by the parameters of erythrocytes. They affect the processes of microcirculation, gas exchange, and metabolism. In this regard, it is of great interest to study changes in erythrocyte parameters in students who previously had low physical activity and started regular sports walking. The study was conducted on 39 young university students who had not previously played sports and experienced low physical activity during their lives.

mHT(Zn) and mHT(Mg) hydrotalcites were fabricated by co-precipitation of Zn2+/Al3+ and Mg2+/Al3+ salt mixtures in the presence of Fe3O4 and used as supports for immobilizing cellulase to form cell@mHT(Zn) and cell@mHT(Mg). The structure and properties of mHT(Zn), mHT(Mg), cell@mHT(Zn), and cell@mHT(Mg) were characterized by Fourier−transform infrared spectroscopy, X-ray diffraction, filtering electron microscopy. The effect of pH, cellulase concentration, and the number of supports on the

The work was carried out on 36 clinically healthy young basketball players aged 17-21 years old, training in the basketball section for at least 3 years. The created control group consisted of 26 clinically healthy young men aged 17 to 21, who had not previously been involved in any kind of sports. In the study, the examined were subjected to ultrasound examination using an SSD-80 "Aloka" device (Japan) with an assessment of the morphological and functional characteristics of the heart

The determination of the frequency of HDFN found in jaundiced newborns in Sudan was the goal of the analysis. In Omdurman maternity inside a Sudanese hospital, 220 mothers and their babies who had jaundice altogether were received in hospital-Sudan and a prospective cross-sectional hospital-based analysis was carried out them. In addition to ABO and Rhesus blood group typing, indirect antiglobulin test (IAT) and direct coomb's test (DAT) was applied for mothers and their jaundiced newborns,

Systematic handball training stimulates the entire body and especially the heart. To improve the methods of practicing handball, it is necessary to further study the aspects of adapting the heart of young handball players to regular training. The study aims to find out the dynamics of the functional capabilities of the heart in youth handball players. The observation was carried out on 25 completely healthy youth handball players with at least 2 years of sports training experience. The control g

Nomophobia is rising among high school students, especially in light of the Covid-19 pandemic, such as social distancing, long-term online learning, and lack of social support. Many studies have also shown that students with high levels of nomophobia have a higher risk of stress. However, very few researchers are interested in studying loneliness as a mediation factor for the relationship between nomophobia and stress . This study investigated whether the loneliness factor is a mediator in the r

Currently, the search for alternative ways to replace the use of antibiotics in animal husbandry is being intensively conducted all over the world, including in Russia. One of the possibilities for the replacement of antibiotics in feed mixtures is the development and testing of probiotics in production conditions. They are biomass of bacteria in vegetative or spore form with a clearly expressed antagonistic activity to the pathogenic and conditionally pathogenic microflora of the gastrointestin

In many fish farms using the warm waters of energy facilities, for long periods, the water temperature can significantly exceed the temperature range favorable for fish rearing. Effective cultivation of juvenile sturgeons in these conditions is a pressing production issue. The purpose of the study is to determine the optimal heat costs for the existing technological stages of growing juvenile sturgeons based on the assessment of the temperature conditions of warm-water farms and their comparison

Toxic and heavy metals are non-biodegradation pollutants in the environment that can affect human health. The levels of these metals can be analyzed with some biological materials, and they may be used to monitor changes in the human body. The levels of selected toxic and heavy metals (Hg, Pb, Ni, Se, Mn, As, Cr, Cd, and Zn) in the scalp hair of male smokers and non-smokers were determined to investigate dietary exposure to various chemical metals pollutants in Saudi Arabia Population. All inves

Biological materials have gained an irreplaceable position as a bio-indicator for environmental pollution with heavy metals. Human hair and nails have come to play an important role in this subject according to the recommendations by the World Health Organization (WHO). The levels of selected toxic and heavy metals (Pb, Zn, Cd, and Ni) in the fingernails and scalp hair of autoworkers in Saudi Arabia were estimated to study exposure to chemical pollutants metals. The samples were collected from d

Under observation were taken 39 young men studying at the university, throughout their lives, who had low muscle activity and started systematic volleyball training 3 times during the week. The control group included 35 young men studying at the university, who for at least the last 2 years systematically participated in volleyball training at least 3 times a week. During the study, traditional biochemical, thematic, and statistical methods for obtaining scientific information were used. After s

The goal of this study was to see how ZnNPs (a green synthesis formulation) affected the physiological, biochemical, and oxidative stress changes generated by experimental diabetes in rats. Twenty female albino Wistar rats were randomly separated into four groups (n=5): control, zinc nanoparticles, diabetic rats, and diabetic rats treated with zinc nanoparticles. Rats were given all types of treatments orally for 21 days. Alloxan (150mg/kg) was used to make rats diabetic. Various parameters were
