    Goal. To develop a personified approach to the management of men with the urogenital chlamydia infection based on studying the molecular and genetic risk factors of the development of complications. Materials and methods. Patients with the urogenital chlamydia infection (20 men with the urogenital chlamydia infection of the lower urogenital tract and 20 men with complicated forms of the urogenital chlamydia infection) and men without any clinical or laboratory signs of STDs and inflammatory diseases of the urogenital tract. The following methods were used in the study: anamnestic, clinical, instrumental (transrectal ultrasonography) and laboratory (microscopic, bacteriological, molecular and biological (PCR, SNaPshot)). Results. According to the study results, the share of cases of ureteritis caused by C. trachomatis amounted to 10.5% of the total share of cases of ureteritis and 13.0% of cases of non-gonococcal ureteritis. The percentage of complicated urogenital diseases caused by C. trachomatis amounted to 34.5% of the total share of complicated forms and 35.7% of noncomplicated forms of the non-gonococcal origin. Subjective clinical signs of complicated forms of the chlamydia infection did not have any reliable distinctions from those observed in case of non-complicated forms of the disease; the infectious process caused by C. trachomatis was characterized by the absence of leukocytosis in the urethra in 30.0% of men with both non-complicated and complicated forms of the disease. The study of the polymorphism of cytokine genes revealed that the CC genotype of IL-6 gene at the -174 locus can serve as a molecular predictor of the complicated course of urogenital chlamydiosis in men while the GC genotype of IL-6 gene at the -174 locus can serve as a molecular predictor of the non-complicated course of urogenital chlamydiosis in men. Based on these results, the authors developed an algorithm for a differential approach to the management of patients suffering from chlamydia infection. Conclusion. A differential approach to the management of men with the urogenital chlamydia infection depending on the molecular predictor of the complicated course of the disease was developed.ЦСль.

    Mechanism of Oxygen Redistribution During Ultra-shallow Junction Formation in Silicon

    Get PDF
    The transport of dissolved oxygen in the Czochralski silicon towards the arsenic-doped ultra-shallow junction was investigated. Ultra-shallow junction was formed by low-energy As+ ion implantation with the subsequent furnace annealing at 750 C-950 C temperatures for the dopant activation. Oxygen and arse-nic redistributions were investigated by secondary ion mass spectrometry (SIMS) technique. The peculiari-ties of defect creation and transformation were studied by the X-ray diffuse scattering technique (XDS). It was found that oxygen concentration in the arsenic redistribution region is increased a few times already after 1 minute of annealing. Increase of annealing time leads to decrease of oxygen accumulation as a re-sult of oxygen transportation to the SiO2/Si interface. As a result the thickness of screen silicon oxide is in-creased by 0.5 nm. This effect is related with the oxygen gettering from the wafer bulk. A physical mecha-nism of the oxygen transfer is discussed. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3527

    The article presents the development and research of drum continuous mixers, most attention is paid to the results of theoretical (using of cybernetic approach) and experimental studies of longitudinal mixing particulate material in rotating drums of continuous action, the influence of internal recycles of material flows, intensifying the process of smoothing the input fluctuations. The authors analyzed the influence of internal recycles material flows, intensifying the process of smoothing the input fluctuations. The results presented in this paper were obtained by the experiments on the smoothing ability determination during which they change the frequency of the drum rotation, the location of the Π“-shaped mixer blades on the drum mixer. The article reported that the studies were conducted on three mixtures which components have different physical and mechanical systems with various dispersed liquid additives and without it

    Formation of silicon nanoclusters in buried ultra-thin oxide layers

    No full text
    The peculiarities of buried layer formation obtained by co-implantation of O2 ions with the energy of 130 keV and carbon ions within the energy range of 30-50 keV have been investigated. The corresponding ion doses for carbon and oxygen ions were equal to 2 x 10¹⁢ cm⁻² and 1.8 x 10¹⁷ cm⁻², respectively. It has been observed that annealing at 1150 Β°C results in enhanced oxygen diffusion towards the region with a maximum carbon concentration. Analysis of X-ray diffraction patterns with a SIMS depth profiles inherent to annealed samples suggests formation of Si nanoclusters in the region with maximum concentrations of carbon and oxygen vacancies. The intensive luminescence has been observed with the maximum at 600 nm, which could be associated with silicon nano-inclusions in thin stoichiometric SiOβ‚‚ layer
