    ALIMENTAȚIA CA FACTOR AL MENȚINERII HOMEOSTAZIEI IMUNE
    (CEP USM, 2024) Bulat, Olga
    Immune homeostasis is a balance between immunological tolerance and inflammatory immune responses, which is a key factor in maintaining the health of the body. Many endo and exogenous factors affect immune homeostasis. One such factor is nutrition. Macro and micronutrients found in food products in turn affect all body systems, including the immune system. This article analyzes the data in order to identify the main macro and microelements involved in maintaining immune homeostasis. It was found that nutrients, from which proteins, fats, carbohydrates can be isolated as macronutrients, as well as vitamins A, groups B, C, D, E, zinc, selenium, copper from micronutrients, more or less affect congenital and acquired immunity.

    CAUZELE ESENȚIALE ALE STRESULUI OXIDATIV AL SPERMATOZOIZILOR ȘI FACTORII CE INDUC STRESUL OXIDATIV ȘI AFECTEAZĂ NEGATIV SPERMATOGENEZA
    (CEP USM, 2024) Bulat, Olga
    Recently, male infertility is increasing. According to statistical data published by the World Health Organization, about 17.5% of the adults suffer from infertility, which means, roughly every sixth person in the world. The oxidative stress, which negatively affects spermatogenesis is one of the causes of infertility. Spermatogenesis is a difficult, highly sensitive process of cell diffe rentiation; different body systems participate in its regulation. Violations of any connection affect the process of spermatogenesis and ultimately affect sperm parameters. The article presents the scientific data on the causes and factors that induce oxidative stress and negatively affect sperma togenesis. The factors favoring its development are numerous, among the most common factors are: inflammation, testicular torsion, increased temperature in the scrotum, varicocele, diabetes, hyperthyroidism, toxins, ionizing radiation, age, sperm freezing.
