At the same time, it is necessary to search for new approaches to the weed control problem, which involves solving a number of issues: determining and analyzing the floral composition of weeds with constant monitoring of contamination to make forecasts and make operational decisions. This work is devoted to the study of these issues. It reveals the features of winter wheat agrophytocenosis formation with the analysis of weed species composition, and shows the effectiveness of the use of herbicides recommended on the basis of mapping. The biological efficiency of the spray mixture of herbicides Verdict + Dinat was 84.1% (by the number of weeds) and 94.9% (by air-dry weight). The agronomic effectiveness of herbicides was expressed in obtaining an increase in yield of 2.67 t/ha, and the profitability level was above the threshold of economic feasibility of the weed management and amounted to 141.8%.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"155 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77475837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since it takes a certain time for immune cells to recognize tumor cells to make an appropriate response, a model of tumor-immune system interaction with time delay is established by considering time delay in this process. The four equilibrium points are solved by simplifying the model using Taylor expansion with a small time delay. Then the stability of each equilibrium point of the system under a small time delay is determined by calculating the characteristic roots of each equilibrium point with numerical simulation software. The results show that the system has a bistability phenomenon. The saddle point and stable node are not affected by the delay, while only the stability of the stable foci changes with the time delay with Hopf bifurcation. This study can help determine the optimal time for tumor treatment and provide a reference for analyzing tumor status and treatment.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80280490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under 808 nm near-infrared light irradiation, the molecule exhibited excellent photothermal conversion efficiency, as well as better photostability and in vivo circulation stability than free ICG. The nanoparticle can respond to reactive oxygen species (ROS) overexpression in the tumor microenvironment and release ICG upon disassembly, resulting in significantly enhanced fluorescence emission at the tumor. In vitro cell experiments demonstrated excellent biocompatibility and photothermal killing effect on cancer cells, indicating that this molecule can serve as a diagnostic and therapeutic agent for fluorescence-guided tumor photothermal therapy.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81639067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 18 diagnostic laparoscopies (DL) were performed, of which 4 cases were converted - laparotomy. In 14 patients cases, DL was completed by therapeutic laparoscopy using minilaparotomy with video-assessment, including 8 patients, resection of the necrotic portion of the intestine was performed with end-to-end anastomosis. In 6 cases, an intestinal stoma was applied through a minilaparotomy.In comparison, after laparoscopic operations with video assessment, mortality was observed of cases 1 patient out of 14, after traditional surgical interventions, mortality was in 25% of cases 1 patient out of 4.

The field experiment was carried out in 2017 and 2018 in Oltrepo pavese area (Lombardia region, northwest Italy, 270 m asl), on a six-year-old vineyard of V. vinifera L. cv. Merlot clone 181 grafted on Gravesac, Guyot trellis, 4,000 vines/ha and not irrigated. Two new protein hydrolysates of plant origin were sprayed twice, just after fruit set and 15 days later, by using 2.5 L/ha. Leaf proteomics and metabolomics were studied in 2017, while productive and qualitative data were recorded in both years at harvest (September 1st, 2017 and August 28th 2018).

The results showed the high efficiency of the method used for the identification of microorganisms in the rumen contents in the studied animals. A large community of bacteria, archaea, protozoa and anaerobic fungi is determined in the rumen contents from highly productive cows with subclinical ketosis. The data obtained allow us to significantly amplify the information on the pathogenesis of subclinical ketosis in cows with high milk productivity. The presence of conditionally pathogenic and pathogenic microflora in sick cows in the rumen contents indicates a violation of rumen digestion, which leads to the development of concomitant non-contagious diseases in animals.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85480218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
