This case study presents a rare instance of cytomegalovirus (CMV) seroconversion in a primiparous woman during her first trimester of pregnancy, accompanied by a significant increase in CMV-specific antibody avidity. The emergence of CMV seropositivity in pregnancy raises concerns due to potential vertical transmission risks. However, the intriguing aspect of this case lies in the unusually high avidity of the CMV-specific antibodies developed post-seroconversion. This phenomenon suggests a previous immune priming event or cross-reactive responses. The case underscores the complexity of CMV infections during pregnancy and the need for careful monitoring and research to comprehend the implications of heightened antibody avidity in the context of maternal-fetal health.

In this research work, an economic assessment of the state of potato cultivation by farms and the factors affecting it was given in order to ensure food security of the population. The analysis was based on the results of a social survey conducted in the farms of districts where potatoes are grown a lot in Samarkand region, using the OLS (Method of Least Squares) model. According to the results of the analysis, it was found that the age of the farm manager (*** p<.01) and cluster membership (** p<.05) have a negative effect on potato production in farms. However, the statistical significance of the work experience of the head of the farm (*** p<.01) and the presence of potato storage in the farm (* p<.1) is scientifically based. Based on the results of the analysis, scientifically based proposals and recommendations were developed.

This study delves into the intricate dynamics of bean pod production by investigating the effects of varying doses of silicon, nitrogen, and molybdenum. Employing a comprehensive experimental approach, the research aims to unravel the optimal conditions for maximizing bean pod yield. Results from controlled experiments showcase the nuanced interplay between these essential elements and their impact on the growth and development of bean pods. The findings contribute valuable insights for agricultural practitioners seeking to optimize cultivation practices and enhance bean pod production in a sustainable and efficient manner.

In poplar groves, worms, false worms, calf-head beetles, leaf-eaters, glassworms, shieldworms and other pests cause the main damage. From coccinellids, which have been effective predators of pests in poplar groves; chilocorus (Chilocorus renipustulatus Scrib) and two-pointed chilocorus (Chilocorus bipustulatus L.), seven-pointed khan girl (Sossinella septempunctata L.). In addition, it is important to reduce the number of pests in this agrocenosis.

Using natural entomophages against harmful insects in the production of crops that are as free as possible from chemicals, clean, environmentally friendly products, we achieve not only human health, but also the purity of the environment, as well as the preservation of many species of living beings found in nature.
