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

The optimal temperature regime for the growth of the CdSxTe1-x solid solution on the silicon surface has been determined. The values of the crystal lattice constant and the thickness of the CdSxTe1-x solid solution at the interface of the n/Si – n/CdSxTe1-x heterostructure are calculated

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

WHEAT YIELD FORECASTING USING NDVI AND CROP STATISTICS IN TASHKENT PROVINCE

Monitoring of crop conditions is important part for the agricultural development system of the country. The production and prediction of wheat yield have direct impact on national and international economies, and play an important role in the food management in Uzbekistan. Today wheat yield production in Uzbekistan is receiving considerable attention from governmental organizations and farmers. The objective of this study is to investigate how we can best predict wheat yield during the vegetation period in Tashkent province. The approach used in this study is based on a crop growth model which is able to quantify the effect of weather conditions on crop growth. The model focuses on indicators from Crop Growth Monitoring System (CGMS) and Remote Sensing data to use year to year variation of wheat yield in Tashkent province. The results showed the positive correlation between the predicted yield and field data (R2 = 0.87) and indicators maximum NDVI and maximum DMP which are driven from remote sensing data are performing the best at regional level

SOME ASPECTS OF ECOSYSTEM SERVICE ANALYSIS IN LOWER AMUDARYA STATE BIOSPHERE RESERVE IN UZBEKISTAN

This research aims to analyze ecosystem services in Lower Amudarya State Biosphere Reserve. This Biosphere Reserve aims to protect and restore landscapes, flora and fauna of tugai forests, including their rare species, to improve ecological condition and sustainably use natural resources and to study natural processes, and promote environmental education, training and awareness. The ecosystems in the Lower Amudarya State Biosphere Reserve provide different ecosystem services to different stakeholders. Nowadays the ecosystem services of the Lower Amudarya State Biosphere Reserve is not fully studied and no information exist on zones. This primarily is due to the increase of water scarcity in the lower part of Amudarya river leads to degradation of tugai forests and biodiversity, increase of desertification and salinity of the territory. In this article there are four different types of ecosystem services are identified and analyzed by existing different zones of the Lower Amudarya State Biosphere Reserve

Soil Electroconductivity as a Proxy to Monitor the Desertification in the Hungry Steppe (Uzbekistan)

Soil salinity caused by desertification is a principal limiting factor for agriculture and lands development in Central Asia. High spatial heterogeneity of soil salinity constrains monitoring desertification and decision making on land management and soil remediation. Low-cost express methods to monitor soil salinity are highly demanded especially at the regions, where implementation of more expensive conventional measurements is constrained due to budget limitations. This research aimed to test onsite and laboratory measurements of soil electroconductivity (EC) as a proxy of soil salinity in the Hungry Steppe (Syrdarya province of Uzbekistan). Four Water Consumer Associations (WCA) with different land quality were analyzed and the EC observations were compared to the results derived from soil salinity maps. An overall satisfactory performance of the indicator was shown with an average 28% of the correctly predicted soil salinity classes. Field EC observations significantly positively correlated to the lab observations (r = 0.57; p < 0.05), but underestimated the absolute values in 66% of the cases. The best performance (53% of corrected predictions) was obtained for the Beruni WCA with the lowers land quality, therefore EC can be recommended as a relevant proxy in areas with high salinity rather than in areas with low concentrations of water-soluble salts. © 2020, Springer Nature Switzerland AG
