Development of regression model of proteins attackability process in meat food (in vitro)

In the presented article the authors consider the issues of development of regression model for process of food digestion by proteolytic enzymes in human body. The authors use correlation analysis. They analyze the main nutritional values and physical and chemical properties of meat products, the modes of heat treatment of semi-finished lamb products. The essential parameters and features are determined to find the dependence between the factor values and efficient values of the basic raw material, which affect the quality of the technological processes and, in general, the finished product. The regression model equation is mathematically calculated by methods of solving K. Gauss linear equations. The standard deviations of parameters are calculated, the initial data are normalized; the matrices of the pair correlation coefficients, lower and upper limits of their values are compiled. Equations of the mathematical regression model of meat proteins attackability by proteolytic enzymes — in vitro (pepsin, trypsin) are developed. It is proved that the obtained equation represents a regression model of the process of meat food proteins attackability by enzymes (pepsin, trypsin and chymotrypsin), depending on the determined 3 essential factors (weight of a meat piece, duration of frying, collagen content in lamb meat). Also this equation reflects the process of lamb digestibility in a digestive tract of a human body

Evaluating multi-year, multi-site data on the energy balance closure of eddy-covariance flux measurements at cropland sites in southwestern Germany

The energy balance of eddy-covariance (EC) measurements is typically not closed, resulting in one of the main challenges in evaluating and interpreting EC flux data. Energy balance closure (EBC) is crucial for validating and improving regional and global climate models. To investigate the nature of the gap in EBC for agroecosystems, we analyzed EC measurements from two climatically contrasting regions (Kraichgau – KR – and Swabian Jura – SJ) in southwestern Germany. Data were taken at six fully equipped EC sites from 2010 to 2017. The gap in EBC was quantified by ordinary linear regression, relating the energy balance ratio (EBR), calculated as the quotient of turbulent fluxes and available energy, to the residual energy term. In order to examine potential reasons for differences in EBC, we compared the EBC under varying environmental conditions and investigated a wide range of possible controls. Overall, the variation in EBC was found to be higher during winter than summer. Moreover, we determined that the site had a statistically significant effect on EBC but no significant effect on either crop or region (KR vs SJ). The time-variable footprints of all EC stations were estimated based on data measured in 2015, complimented by micro-topographic analyses along the prevailing wind direction. The smallest mean annual energy balance gap was 17&thinsp;% in KR and 13&thinsp;% in SJ. Highest EBRs were mostly found for winds from the prevailing wind direction. The spread of EBRs distinctly narrowed under unstable atmospheric conditions, strong buoyancy, and high friction velocities. Smaller footprint areas led to better EBC due to increasing homogeneity. Flow distortions caused by the back head of the anemometer negatively affected EBC during corresponding wind conditions.</p

Изучение маркеров апоптоза, пролиферации и ангиогенеза у больных раком яичника, получивших сопроводительную иммунотерапию

The aim of the work was to study a number of molecular biological tumor markers as selection criteria methods of accompanying extracorporeal immunopharmacotherapy(EIFT) in patients with ovarian cancer (OC). The object of the study were 30 patients with OC with II–III clinical stages of the disease who were treated in gynecological cancer RORC MoH Uzbekistan office from 2009 to 2011 years and treated with standard combination therapy. Most of the patients with OC (83.3, 86.7 and 80.0%, respectively) were present molecular biological markers p53, VEGF and Ki‑67. At the same time, themarkers HER‑2/neu and EGFR were found in 20.0% of patients and 30.0 respectively. It is shown that the greatest prognostic value regarding the efficacy of the treatment of patients with OC have tumor markers p53, VEGF and Ki‑67, and the level of proliferative activity (PA) of the tumor. The greatest effect in increasing the 5-year survival of patients immunotherapy has provided the accompanying diagram including EIFT withplasmapheresis. Positive okomarkerov level of p53, VEGF and Ki‑67 in patients with OC, along with high PA tumors can serve as a basis for this category of patients with immunotherapy accompanying EIFT. In the case of positive values of all the above molecular biological factors, we recommend carrying out the accompanying EIFT with plasmapheresis, which can significantly increase the effectiveness of standard anticancertreatment schemes.Целью работы явилось изучение ряда молекулярно-биологических маркеров опухоли в качестве критериев выбора методов сопроводительной экстракорпоральнойиммунофармакотерапии (ЭИФТ) у больных раком яичника (РЯ). Объектом исследования служили 30 больных РЯ с II–III клиническими стадиями заболевания, проходивших лечение в онкогинекологическом отделении РОНЦ МЗ РУз с 2009 по 2011 гг. и получивших стандартное комбинированное лечение. У большей части больных РЯ (у 83,3, 86,7 и 80,0% соответственно) присутствовали молекулярно-биологические маркеры p53, VEGF и Ki‑67. В то же время, маркеры HER‑2/neu и EGFR обнаруживались у 20,0 и 30,0% пациенток соответственно. Показано, что наибольшей прогностической значимостью в отношении эффективности лечения больных РЯ обладают онкомаркеры p53, VEGF и Ki‑67, а также уровень пролиферативной активности (ПА) опухоли. Наибольший эффект в увеличении5-летней выживаемости пациенток оказывала схема сопроводительной иммунотерапии, включающая ЭИФТ с плазмаферезом. Положительный уровень окомаркеров p53, VEGF и Ki‑67 у больных РЯ наряду с высокой ПА опухоли могут служить основанием для проведения данной категории пациенток сопроводительной иммунотерапии с ЭИФТ. В случае положительных значений всех рассмотренных молекулярно-биологических факторов, мы рекомендуем проведение  сопроводительной ЭИФТ с плазмаферезом, что может существенно увеличитьэффективность стандартных схем противоопухолевого лечения

Soil salinity mapping by different interpolation methods in Mirzaabad district, Syrdarya Province

Soil salinity is an important global issue and especially on irrigated areas due to its great impact on a crop production system. Proper soil salinity mapping can improve land use management. The goal of this study was to improve the accuracy of soil salinity mapping with the two objectives (1) to evaluate different interpolation methods during soil salinity mapping and (2) to identify of differences in soil salinity assessments in irrigated land of Mirzaabad district which is most affected by salinity in Syrdarya province of Uzbekistan. Soil salinity data measured by EC meter was obtained from Syrdarya Hydromelioration Expedition. Different four interpolation methods such as Inverse Distance Weighted (IDW) with power 1, 2, and 3, and Kriging techniques were used for the generation continuous surface of soil salinity maps. The cross-Validation method with the assessment of Root Mean Square Errors (RMSE) shows that IDW with power 2 (IDW-2) most accurate. The maximum difference reached between IDW-2 and IDW-1 on the slightly saline area where the value decreased by 55% of the total irrigated land of the district. Minimum differences reached on IDW-3 on moderated saline class and higher than IDW-2 on 408.6 ha
