Introduction. The pandemic spread of a new coronavirus infection, COVID-19, has caused global emergency and attracted the attention public health professionals population all countries. A significant increase in number cases SARS-CoV-2 infection demonstrates urgency finding drugs effective against this pathogen.The aim work was to evaluate vitro antiviral efficacy human recombinant alpha-2b int...
پوشش گیاهی بهعنوان یکی از مهمترین اجزای هر اکوسیستم به شمار میرود. تعیین میزان درصد پوشش گیاهی بهمنظور فهم تعاملات بین زمین و اتمسفر، تأثیر آن بر اقلیم، میزان فرسایش خاک، بررسی خشکسالی، و مدیریت منابع طبیعی بسیار ضروری است. هدف از این پژوهش، تخمین درصد پوشش گیاهی با استفاده از شاخصهای رایج پوشش گیاهی است. در این تحقیق از تصویر ماهوارهای alos (avnir)مربوط به تیر ماه 1388 و مطالعات میدان...
Large-scale coastal reclamation has caused significant changes in Spartina alterniflora (S. alterniflora) distribution in coastal regions of China. However, few studies have focused on estimation of the wetland vegetation biomass, especially of S. alterniflora, in coastal regions using LiDAR and hyperspectral data. In this study, the applicability of LiDAR and hypersectral data for estimating S...
Multi-angle remote sensing can either be regarded as an added source of uncertainty for variable retrieval, or as a source of additional information, which enhances variable retrieval compared to traditional single-angle observation. However, the magnitude of these angular and band effects for forest structure parameters is difficult to quantify. We used the Discrete Anisotropic Radiative Trans...
View angle effects present in vegetation indices are either being seen as unwanted information or as an additional source of information. However, the magnitude of these angular effects remains for most indices unknown. We use the ESA-mission CHRISPROBA (Compact High Resolution Imaging Spectrometer–Project for On-board Autonomy) providing spaceborne imaging spectrometer and multidirectional dat...
Introduction. Interferons are produced in response to the presence of pathogens cells and responsible for proper formation immune reaction. Preliminary data obtained studies properties recombinant interferon gamma (IFN-γ) that involved patients with community-acquired pneumonia (including bacterial), acute respiratory viral infection (ARVI), influenza new coronavirus have shown promising result...
The article presents the analysis of widespread spectral indexes results Earth remote sensing data thematic processing to reveal most representative one for applying under conditions critical increase groundwater level and salinity as well salinized soil. Long-term monitoring multispectral images LandSat-8 satellite were collected Golodnostepsky irrigation land. Sites with disturbing ameliorati...
Chronic pelvic inflammatory disease (PID) in women remains a problem due to the importance of medical consequences. The study receptor apparatus neutrophilic granulocytes (NG) involved anti-infective protection diseases various etiologies seems be relevant. Aim: clarify features variants quantitative and phenotypic changes subsets NG CD11b + CD64 - CD32 CD16 , immunocompromised during exacerbat...
Of the acute respiratory viral infections in farms of Udmurt Republic, parainfluenza-3, syncytial infection, infectious rhinotracheitis, diarrhea are most common. For prevention these cattle diseases, inactivated combined vaccine Kombovak and R. is used. Despite widespread use this vaccine, there an ambiguous situation UR percentage ARVI incidence extremely variable. Along with general economic...
