The antibacterial and antifungal properties were determined using the double serial dilution method. It was established that all of the samples of acacia, linden, and sunflower honey possess high antibacterial activity. The bioactivity of the samples of honey was proven to be dependent on the type and origin of honey. Sunflower honey has higher antibacterial potency than linden, but linden honey is more active than acacia. Both Gram-positive and Gram-negative bacterial species proved to be susceptible to Moldavian honey. Acacia, linden, and sunflower honey, possess high antibacterial potency against S. aureus and P. aeruginosa even at a dilution of 1:16 (2.5%). The studied samples showed weak antifungal activity against Candida albicans, with the MIC determined at 1:2 dilution (20%). For linden and sunflower honey, the antifungal activity was higher than for acacia honey. The samples with the best bioactivity (sunflower honey) contain a higher amount of free acids, had lower pH values of the honey solution, and these samples also have the highest content of OMF.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135911144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose an Efficient Net algorithm based recognition method for vehicle front-end and vehicle rear-end recognition to address the shortcomings of the current methods used for vehicle front-end and vehicle rear-end recognition, and verify the reliability of the algorithm using experiments. Algorithm systematically investigates model scaling, the backbone network makes extensive use of the MBConv structure to extract the feature maps, which cuts short the time required for model training, and the structure introduces the SE module to perform global averaging pooling operations in the channel dimension direction to enhance model performance, so that the network has the dual advantages of network model size and recognition accuracy at the same time. Based on the above findings, we improve the inverse residual module of the backbone feature extraction network EfficientNet by introducing the coordinate attention mechanism (CA) to average the spatial feature information in X-axis and Y-axis dimensions respectively, with the feature layer size and number of channels unchanged, and change the residual edge to shorten the input and output of high-dimensional channels to improve the accuracy of model feature extraction. Meanwhile, this paper introduces a depth-separable convolutional neural network and agent-normalized activation in the mobile flip-flop convolutional module to offset the two different dimensions of X-axis and Y-axis between each convolutional layer but the two main sources of non-normalization, so as to achieve the improvement of the target detection rate and accuracy.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136302010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Honório-França, Eduardo L França, Joaquim M. da Silva","doi":"10.59879/jqnvx","DOIUrl":"https://doi.org/10.59879/jqnvx","url":null,"abstract":"Breast cancer is a multifactorial disease resulting from genetic, immunological, and environmental interactions. Among environmental factors, it is known that diet plays a key role in cancer etiology. In addition, there is evidence that human milk may confer long-term benefits, such as reducing the risk of developing cancer. In breast cancer, macrophages represent one of the main components of the immune infiltrate. These cells contribute to the progression and spread of tumors, but studies suggest that these cells can be reprogrammed to act as a potent antitumor immune response. In addition to the mechanisms involved in the interaction between immune system cells and tumor progression, studies have related the use of plants as an alternative for tumor immunotherapy, among which the Cerrado bryophytes stand out. Thus, this study aimed to evaluate Lejeunea cancellata extract as a modulating agent in breast cancer (MCF-7) tumor cell lines and human colostrum. Therefore, the natural extract of Lejeunea cancellata was prepared, and from this, immunophenotyping assays, cytokine dosage, and data analysis were performed. There was an increase in the secretion of the inflammatory cytokines IL-1 and IL-8 in the groups cocultured with MCF-7 in the presence of Lejeunea cancellata. Furthermore, a decrease in the expression of CD14 (macrophages), CD163, CD197+ and CD86+ (M1 macrophages), and CD197- and CD86+ (M2 macrophages) is observed in colostrum cells when they were treated with Lejeunea cancellata in coculture with MCF-7 cells. These findings indicate that colostrum macrophages differentiate into two phenotypes, M1 and M2. When cocultured with MCF-7 breast tumor cells, the bryophyte Lejeunea cancellata reduces the percentage of both macrophage phenotypes. This data suggests that the bryophyte can inhibit the formation of inflammatory infiltrates caused by M1 macrophages in the tumor microenvironment and the progression of M2 macrophages that promote tumorigenesis.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71244281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it is currently impossible to meet the demand of organic products in the world, it can at least reduce environmental problems. Consumer knowledge of a sustainable environment is seen from the knowledge of green products, Green Finance, Green Living, Green Transportation, Green Producers, Green Consumers, Green Communication , Green Institutions and Green Creativity. The purpose of this study is to see the perception and consumer behavior of organic products in supporting a sustainable environment. The study was conducted in June – October 2022 with 183 respondents using simple random sampling. The consumer criteria are consumers who often buy from these three organic commodities in daily shopping patterns and the data is analyzed with Multidimensioan Scalling (MDS). The results showed that consumer perceptions of sustainable environmental trends say that organic vegetables and chickens have similarities, then rice and organic vegetables. While rice and organic chicken have no similarities. Consumer behavior that is oriented towards being environmentally friendly is revealed that consumers in buying organic rice consider many factors including green products, green producers, green communication, and green institutions. As for organic chicken factor green consumer, and green creativity. Furthermore, for organic vegetables, only green finance. Thus, consumers in buying organic rice consider many factors compared to buying organic chicken and vegetables. This indicates that knowledge of sustainable environment still needs to be conveyed to the community considering that rice is a staple food in Indonesia and also other countries in the world.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71244326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pressure on intensive care units has been significant. In many countries, including Iceland, there was a need to increase the capacity of these units to meet the growing demand for intensive care spaces, especially at the start of the pandemic. At Landspitali, the National University Hospital of Iceland (hereafter referred to as Landspitali), increasing unit capacity was a large-scale and extensive project where project management methodologies were utilised to assess risks and develop response plans. Using information gathered from interviews, this study explores the experience of managers in Landspitali’s surgical and intensive care unit in preparing for the pandemic and their evaluations of the project's success. The interviews were conducted in the autumn of 2020 after the first wave of the pandemic had passed in Iceland. The study utilised a qualitative methodology. Eight managers from Landspitali’s surgical and intensive care unit participated in semi-structured interviews. The study employs thematic analysis to analyse the findings. The data analysis reveals four themes. The first theme, ‘dealing with the unknown’, illustrates the uncertainty that was prevalent at the beginning of the pandemic. The second, ‘one step ahead’, reveals how the managers utilised resources both within and outside the hospital to prepare the intensive care unit for COVID-19 patients. The third theme, ‘fighting the virus’, highlights the challenges the managers encountered throughout the process. Lastly, the ‘in this together’ theme focuses on how the staff came together to accomplish the project. The initial uncertainty during the preparation phase posed difficulties for the managers. Working in accordance with existing response plans and utilising the findings of the situation analysis made it possible for managers to organise how space, personnel, and supplies would be utilised and thus increase the surge capacity of the units. The respondents' main challenges were facility adaptation and ensuring adequate staffing. Cooperation and solidarity among the staff, along with well-timed preventive measures implemented by the authorities, proved crucial to the success of Landspitali’s intensive care unit in dealing with the pandemic.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135798668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
