Nickel and human sperm quality: a systematic review.

BMC Public Health

December 2024

Northwest Public Health Research Center, 4 2-Sovetskaya street, Saint-Petersburg, 191036, Russian Federation.

Background: Reproductive effects of chronic exposure to nickel (Ni), including sperm quality, have been a matter of debate given that published studies yielded contrasting results. We have, therefore, planned to systematically search and analyze medical literature with the aim to ascertain the association of exposure to nickel with the sperm quality in humans.

Materials And Methods: We systematically searched Pubmed, Scopus and Embase for studies reporting the association of Ni with the sperm quality in humans with no time or language limits and used PRISMA to report the findings.

An urgent problem in the agricultural science of livestock production is the adequate feeding of the queens of farm animals, in particular sheep kept on year-round pasture, especially in the second half of pregnancy and the first half of lactation. These periods are the most stressful, since the uterus does not receive enough necessary nutrients for the normal functioning of the body, embryonic and post-embryonic development of the offspring. In this regard, the purpose of our research was to increase the usefulness of the diet queens by carrying out additional feeding crushed barley with the inclusion of a mineral supplement developed taking into account the chemical composition of feed in Kazakhstan.

Human Exposure to Asbestos in Central Asian Countries and Health Effects: A Narrative Review.

Med Lav

December 2024

Department of Health Sciences; Course of Research Doctorate in Public Health Sciences, University of Milan, Milan, Italy/Occupational Health Unit, Santi Paolo e Carlo Hospital, Milan, Italy.

The discovery of the detrimental effects of asbestos on human health came long after its widespread use, with the first scientific evidence of asbestos-related diseases emerging in the late 19th and early 20th centuries. Despite efforts to ban its use, asbestos continues to be mined and used in Central Asia (as well as in Russia, China, and other countries). To gain a deeper understanding of the situation in Central Asia, we have conducted a systematic review of scientific literature on the use of asbestos, exposure assessment, and health consequences of asbestos exposure in this geographic area.

Background: The recent announcement of the next WHO State of the World's Nursing and Midwifery Reports calls for a review of the state of nursing and midwifery worldwide. In the WHO European region, a broad set of health system reforms have been introduced in Central Asian countries (CACs), namely, the Republic of Kazakhstan, the Kyrgyz Republic, the Republic of Tajikistan, Turkmenistan and the Republic of Uzbekistan. These reforms have become the focus of a series of sub-regional policy dialogs between CACs, led by government chief nursing and midwifery officers, to accelerate the implementation of a package of policies to strengthen the capacity of nurses and midwives and build health system resilience.

MDM2 up-regulates the energy metabolism in NSCLC in a p53-independent manner.

Biochem Biophys Res Commun

January 2025

Institute of Cytology, Russian Academy of Sciences, 194064, St. Petersburg, Russia. Electronic address:

Although an E3 ligase MDM2 is the major negative regulator of the p53 tumor suppressor, a growing body of evidence suggests its p53-independent oncogenic properties. In particular, MDM2 has been shown to regulate serine metabolism independently of p53 status in several types of neoplasia, including NSCLC. Using the GSEA approach and publicly available molecular data on NSCLC tumors, our bioinformatics data suggest that MDM2 affects a number of metabolic genes, particularly those encoding components of the electron transport chain (ETC).

Article Synopsis
  • The study investigates the prevalence of nasopharyngeal Streptococcus pneumoniae carriage (NSPC) in infants under two years, focusing on differences by vaccine types and country income levels.
  • A systematic review of 49 articles revealed a highest NSPC prevalence in infants aged 4 to 6 months and 7 to 9 months, particularly elevated in low-income countries.
  • The findings stress the importance of monitoring NSPC trends, especially non-vaccine serotypes, to inform vaccination strategies and reduce pneumococcal disease burden in infants.

Electromagnetic Imaging for Breathing Monitoring.

Sensors (Basel)

December 2024

Special Design and Technology Bureau "Granit", 292 Hussainov Street, Almaty 050060, Kazakhstan.

The search for new non-invasive methods of investigating the functioning of human internal organs is an urgent task. One of these methods for assessing the functioning of the human respiratory system is electromagnetic sensing, which is based on a significant difference in the dielectric permittivity of muscle tissue and air. During breathing, when the lungs are filled with air, the dielectric permittivity of the lungs decreases, which leads to a change in the level of the electromagnetic signal passing through the body.
