Evaluation of the effectiveness of post-destructive rehabilitation in patients with HPV-associated cervical disease

The evaluating of the results of rehabilitation measures after destructive treatment in patients with cervical leukoplakia associated with papillomavirus infection has been analyzed. It has been established that the use of the antibacterial drug Elzhina at the stage of rehabilitation is necessary to prevent secondary bacterial infection and improve regenerative processes, and the use of the vaginal gel Biofam, which includes lactic acid, glycogen and thyme oil, provides a combined advantage in colonization of the vagina with a lactobacilli flora and restores the pH level, which prevents the further reproduction of opportunistic pathogenic microflora and contributes to a reliable the timing of epithelization, the reduction in the number of relapses.Проведен анализ результатов реабилитационных мероприятий после деструктивного лечения пациенток с лейкоплакией шейки матки, ассоциированной с папилломавирусной инфекцией. Установлено, что применение антибактериального препарата Эльжина на этапе реабилитации необходимо для предупреждения вторичного бактериального инфицирования и улучшения регенераторных процессов, а использование вагинального геля Биофам, в состав которого входит молочная кислота, гликоген и тимьяновое масло, обеспечивает комбинированные преимущества в колонизации влагалища лактобациллярной флорой и восстанавливает уровень pH что препятствует дальнейшему размножению условно-патогенной микрофлоры и способствует достоверному сокращению сроков зпителизации, уменьшению количества рецидивов

О возможной роли эндогенных модуляторов β-адрено- и М-холинореактивности в патогенезе бронхиальной астмы

Ability of blood sera from 19 asthmatic children and 56 asthmatic adults to modify reactivity of β-adrenoreceptors and M-cholinoreceptors in isolated smooth muscles of the uterus horns from nonpregnant rats (n = 234) and cow trachea (n = 36) have shown that asthma presence did not change serum myocyte-stimulating activity but reduced the sensitizing activity of β-adrenoreceptors and the blocking activity of M-cholinoreceptors and enhanced the blocking activity of β-adrenoreceptors. The similar changes were also seen in child urine and indicated the decreased level of the endogenous sensitizer of β-adrenoreceptors and the growing level of the endogenous blocker of β-adrenoreceptors in asthma patients and the decreased level of endogenous blocker of M-cholinoreceptors in certain asthmatics. These events could provide asthma occurrence.На продольных полосках рога матки небеременных крыс (n = 234) и циркулярных полосках трахеи коров (n = 34) при исследовании сыворотки крови 19 детей и 56 взрослых показано, что при бронхиальной астме (БА) не изменяется миоцитстимулирующая активность сыворотки, но снижается β-адреносенсибилизирующая активность, возрастает β-адреноблокирующая активность и снижается М-холиноблокирующая активность (у части пациентов она возрастает). Подобные изменения характерны и для мочи детей. Это указывает на то, что при БА снижается содержание эндогенного сенсибилизатора β-адренорецепторов (ЭСБАР), возрастает содержание эндогенного блокатора β-адренорецепторов (ЭББАР), и у части пациентов снижается содержание эндогенного блокатора М-холинорецепторов (ЭБМХР). Эти изменения могут способствовать формированию БА

A 300-year record of sedimentation in a small tilled catena in Hungary based on δ13C, δ15N, and C/N distribution

Purpose Soil erosion is one of the most serious hazards that endanger sustainable food production. Moreover, it has marked effects on soil organic carbon (SOC) with direct links to global warming. At the same time, soil organic matter (SOM) changes in composition and space could influence these processes. The aim of this study was to predict soil erosion and sedimentation volume and dynamics on a typical hilly cropland area of Hungary due to forest clearance in the early eighteenth century. Materials and methods Horizontal soil samples were taken along two parallel intensively cultivated complex convex-concave slopes from the eroded upper parts at mid-slope positions and from sedimentation in toe-slopes. Samples were measured for SOC, total nitrogen (TN) content, and SOMcompounds (δ13C, δ15N, and photometric indexes). They were compared to the horizons of an in situ non-eroded profile under continuous forest. On the depositional profile cores, soil depth prior to sedimentation was calculated by the determination of sediment thickness. Results and discussion Peaks of SOC in the sedimentation profiles indicated thicker initial profiles, while peaks in C/N ratio and δ13C distribution showed the original surface to be ~ 20 cm lower. Peaks of SOC were presumed to be the results of deposition of SOC-enriched soil from the upper slope transported by selective erosion of finer particles (silts and clays). Therefore, changes in δ13C values due to tillage and delivery would fingerprint the original surface much better under the sedimentation scenario than SOC content. Distribution of δ13C also suggests that the main sedimentation phase occurred immediately after forest clearance and before the start of intense cultivation with maize. Conclusions This highlights the role of relief in sheet erosion intensity compared to intensive cultivation. Patterns of δ13C indicate the original soil surface, even in profiles deposited as sediment centuries ago. The δ13C and C/N decrease in buried in situ profiles had the same tendency as recent forest soil, indicating constant SOM quality distribution after burial. Accordingly, microbiological activity, root uptake, and metabolism have not been effective enough to modify initial soil properties

Soil management of sugarcane fields affecting CO2 fluxes

ABSTRACT The harvesting system of green sugarcane, characterized by mechanized harvesting and no crop burning, affects soil quality by increasing the remaining straw left on the soil surface after harvesting, thus, contributing to the improvement of physical, chemical, and microbiological soil attributes, influencing CO2 fluxes. This study aimed to evaluate CO2 fluxes and their relation to soil properties in sugarcane crops under different harvesting managements: burned (B), Green harvesting for 5 years (G-5) and Green harvesting for ten years (G-10). For this, a 1 ha sampling grid with 30 points was installed in each area, all located in the Northeast of São Paulo State, Brazil. In each point, CO2 fluxes were measured and the soil was sampled to analyze the microbial biomass, physical (soil moisture and temperature, mean weight diameter, bulk density, clay, macroporosity and microporosity) and chemical characterization (pH, organic C, base saturation and P). The CO2 fluxes were divided into four quantitative criteria: high, moderate, low and very low from the Statistical Division (mean, first quartile, median and third quartile) and the other data were classified according this criterion. The Principal Component Analysis (PCA) was used to identify the main soil attributes that influence CO2 fluxes. The results showed that G-10 CO2 fluxes were 28 and 41 % higher than those in the G-5 and B treatments, respectively. The PCA analysis showed that macroporosity was the main soil attribute that influenced the high CO2 fluxes

Electrodeposition of Co-Ni-MoxOy Powders: Part I. The Influence of Deposition Conditions on Powder Composition and Morphology

The Co-Ni-MoxOy powders were obtained electrochemically at a constant current density from ammonia electrolyte. Ni and Co were anomalously deposited, inducing Mo deposition, which cannot be deposited separately from aqueous solutions. The obtained Co-Ni-MoxOy powders were investigated by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and scanning electon microscope (SEM) methods. Based on the obtained experimental results, it was concluded that the particle size of deposited powders is influenced by the chemical composition of the electrolyte and current density imposed. XRD results suggested that obtained powders were of amorphous structure, although a Co3Mo compound can be formed if certain experimental conditions are applied
