A 54-year-old housewife received total parenteral nutrition (TPN) because of an intestinal fistula and total wound breakdown after an emergency operation for perforation of the ileum and diffuse peritonitis. The TPN regimen reversed the catabolism and resolved the abdominal wound and enterocutaneous fistula. Zinc and copper were not supplemented because there was no licensed parenteral trace element solution available. At week 17 of TPN, eczematoid dermatitis appeared on the face, nasolabial folds and chin, and the perineal area. These changes, coinciding with a serum zinc level of 20 micrograms/dl, were consistent with zinc deficiency. Zinc supplementation was commenced giving 6 mg of elemental zinc intravenously daily. The response to zinc therapy was very dramatic. Not only did the serum zinc level increase, but the skin changes returned to normal within 7 days. The patient gradually resumed her usual diet and TPN was discontinued after an approximate duration of 21 weeks. She was later discharged in good health.

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).
