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).
Chloride perovskites are semiconductors with a near-ultraviolet bandgap that are promising for applications in optoelectronics and photonics. One of the most studied representatives of this family is the methylammonium lead chloride MAPbCl (MA = CHNH). Low-temperature luminescence spectroscopy of this material demonstrates a complex emission structure.

- Iron phosphide/carbon (FeP/C) materials show great promise as electrocatalysts for the oxygen reduction reaction (ORR), but finding variants with improved catalytic activity for biocatalysis remains challenging.
- FeP/carbon dots (FeP/CDs) have been developed to demonstrate enhanced peroxidase-like (POD-like) catalytic activity, achieving a specific activity of 31.1 U/mg, which is double that of standard FeP.
- The antibacterial efficacy of FeP/CDs nanozymes is significant, showing a 98.1% effectiveness and outperforming other nanozymes such as FeP and FeO/CDs by varying degrees.
Triphenylphosphine functionalized carbon dots (TPP-CDs) showcase robust mitochondria targeting capacity owing to their positive electrical properties. However, TPP-CDs typically involve complicated synthesis steps and time-consuming postmodification procedures. Especially, the one-step target-oriented synthesis of TPP-CDs and the regulation of TPP linkage modes remain challenges.
