The zinc deficiency affects approximately a third of the world population, principally in the developing countries, the rural areas and in the poorest communities, where this micronutrient deficiency is one of the most prevalent risk factor for nutrientrelated diseases. This paper compiles scientific advances about the key role of the essential trace element zinc in the neurogenesis control, brain function and cognitive development. The aim of this work is to generate in health professionals, interest about the zinc deficiency effects in neuro-intellectual development and its negative impact in the cultural, economic and social development of the countries.

Background: Childhood obesity and the rate of its spread is a serious threat to the reproductive health of the nation, especially among boys, being a background for delaying sexual development and further disrupting fertility.
Aim: To study the peculiarities of the ratio of the level of leptin and a number of toxic and essential chemical trace elements in biological environments in adolescent boys aged 13-14 years with obesity and delayed sexual development.
Materials And Methods: Three groups of adolescents aged 13-14 years were studied and formed: the main ones - with constitutional exogenous obesity of 1-2 degrees (1-20 boys without secondary signs of puberty; 2 - 24 boys with 2-4 stages of puberty according to Tanner) and comparisons (3 - 15 boys with normal body weight and without deviations in puberty).

Pharmaceutical supplementation and dietary fortification are the most common approaches to reducing vitamin deficits. To improve the health and nutritional value of crops, agronomic biofortification necessitates the direct application of nutrients. Producers using micronutrient fertilizers to increase the fortification of crops are essential to the success of biofortification.

Protein phosphatases are critical for regulating cell signaling, cell cycle, and cell fate decisions, and their dysregulation leads to an array of human diseases like cancer. The dual specificity phosphatases (DUSPs) have emerged as important factors driving tumorigenesis and cancer therapy resistance. DUSP12 is a poorly characterized atypical DUSP widely conserved throughout evolution.

The management of micronutrients, such as boron (B) and zinc (Zn), is critical for plant growth and crop yields. One method of rapid intervention crop management to mitigate nutritional deficiency is the foliar supply of B and Zn. Our study investigates the effect of foliar-supplied B and Zn availability on the global transcriptional modulation in soybean (Glycine max).
