This paper reviews the extraction method and chemical composition of star anise essential oil, and discusses its antibacterial effect. Coriander seeds selected from China were used to extract coriander essential oil by distillation extraction, and its compound components were qualitatively and quantitatively analyzed by gas chromatography-mass spectrometry (GC-MS), and the main components were evaluated by Fourier transform infrared spectroscopy (FTIR). The main component was detected to be anethole, with a content of 80%~90%. In addition, there was a small amount of anisaldehyde. Antibacterial experiments were carried out on selected opportunistic microorganisms, and it was found that star anise essential oil had significant effects on Staphylococcus aureus, Escherichia coli, Bacillus cereus, and Proteus.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"179 1","pages":"04001-04001"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.bio-conferences.org/articles/bioconf/pdf/2025/30/bioconf_idsisa2025_04001.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adenylyl cyclase 1 (ADCY1) is recognized for its pivotal role in cardiac pathophysiology. Nonetheless, the involvement of ADCY1 in DOX-induced cardiotoxicity (DIC) remains not well-studied. This study aimed to elucidate the role of ADCY1 in DIC, in particular whether ADCY1 affects oxidative stress and myocardial injury. Our findings indicate that ADCY1 expression is downregulated in DOX-treatment AC16 cardiomyocytes with a DOX concentration- dependent manner. Silencing of ADCY1 further exacerbated DIC. It was manifested by the elevated levels of ANP, BNP, LDH oxidative stress compared with DOX treatment group. Conversely, over expression of ADCY1 mitigated these adverse effects induced by DOX. Our study elucidates the cardioprotective effects of ADCY1 by attenuating DOX-induced myocardial injury, oxidative stress . It provides a novel perspective for the development of therapeutic strategies aimed at reducing cardiac toxicity in patients undergoing DOX treatment.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"174 1","pages":"01014-01014"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.bio-conferences.org/articles/bioconf/pdf/2025/25/bioconf_icbb2025_01014.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural design of such a robot is quite complex. However, this is usually done once at the beginning of the design process and the dynamic loads can only be estimated, leading to huge safety margins. In this paper, a digital twin approach to structural mechanics is proposed. Each feature of the environment (each tree, soil, etc.) as well as the robot itself can be represented by a digital twin. Rigid body dynamics are used to record all acting forces and impulses during the operation. These serve as input for finite element analysis, thus providing a holistic modelling framework.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"145 1","pages":"05005-05005"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.bio-conferences.org/articles/bioconf/pdf/2024/64/bioconf_ForestryForum2024_05005.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on latex enhanced immunoturbidimetry, automatic biochemical analyzer was used to establish the linear relationship between the β2-microglobulin standard with different concentrations and the absorbance change value of 546 nm, and optimize the antibody source, latex microsphere particle size, activator concentration, sealer concentration and buffer system in the β2-microglobulin detection system. The linear range and accuracy of the optimized detection system were evaluated. After optimization, the optimal detection system was obtained, and its detection linear range was 0.2-30 mg/L, which reached the upper limit of the reference range of β2-microglobulin in normal population by 10 times, and the accuracy was in line with clinical standards, which solved the false negative problem of high-concentration samples in clinical testing, eliminated the repeated dilution process of high-concentration samples, simplified the detection steps, and improved the detection accuracy.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"111 1","pages":"02013-02013"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.bio-conferences.org/articles/bioconf/pdf/2024/30/bioconf_icbb2024_02013.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The corrosion monitoring technique includes the weight loss method and surface analysis by optical microscope. The extracted lignin was characterized using 13CNMR. The results showed clear evidence of Kraft lignin’s and tannin's corrosion inhibition behavior of carbon steel alloys immersed in 0.5 M HCl solutions. As increasing concentration, Kraft lignin and tannin became more effective inhibitors. Furthermore, Kraft lignin showed more effectiveness as a corrosion inhibitor than tannin.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"97 1","pages":"00026-00026"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.bio-conferences.org/articles/bioconf/pdf/2024/16/bioconf_iscku2024_00026.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the current situation, sustainable use of PPP is a main objective and priority. The decisions making of using PPP of 235 winegrowers from Palmela region, which do not have regular technical assistance, were assessed during 2016 until 2019. The data analysed included the number of applications, the dosages used and the compliance of pre-harvest interval (PHI). For each year, it was observed that a winegrower, on average, made seven treatments, although the tendency is a decrease to reduce the number of treatments. The PPP most used belong to the groups 3 (Triazoles), M02 (Inorganic) and M04 + 4 (Phthalimides + Phenyl Amides) according FRAC Code. Regardless of the climatic conditions and the disease pressure in the vineyard, the winegrowers used PPP every 14 days. Fear and “empiric experience” sometimes overtake knowledge and technology. That could only be changed with trust between technical assistance and farmers. That could be the solution to face the mentioned challenges and to offer sustainable wines from Palmela region.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87489724","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}

The rail threads that make up these lines are an integral part of the traction network and, therefore, the traction current is channeled through them. Bearing this in mind, the signals of these channels operate under the conditions of strong interference from traction current. At present, continuous automatic locomotive signalling systems continue to improve, so it is necessary to have information on the relationship between the immunity of their channels, in particular under conditions of traction current interference, from different signal parameters, such as carrier frequency. This article deals with the method of evaluating the influence of the frequency of the carrier signal on the noise resistance of the channels comprising rail and inductive rail lines.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"127 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75832619","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}
