To do this, DNA was extracted from the blood of buffaloes and was subjected to PCR testing and sequencing of the genes NC3 and MICB. The RNA extracted from the placentome and intercotyledonary region of buffaloes in their first (n = 6), second (n = 6) and third (n = 6) trimesters of gestation was subjected to real-time PCR. Explants were created using the chorioallantoic membrane and two experimental groups were established: control and stimulated with LPS for four hours to evaluate the gene expression profile. Analysis on the sequences obtained showed that the genes NC3 and MICB of buffaloes were homologous with those of cattle, with high similarity in the analysis on the sequence variation pattern. The gene expression analysis showed that the genes assessed were transcribed at stages and in placental tissue that differed from what was seen in cattle. The transcription of these genes varied in the tissues studied, with greater transcription of MICB in the intercotyledonary region over the first third of gestation, while the genes studied in the placentome presented low rates of transcription. The trophoblastic cells of the chorioallantoic membrane stimulated with LPS for six hours did not present non-classic MFC-I transcription alterations. The present study therefore provides additional knowledge regarding the immune regulation of placental tissues of buffaloes.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e281304"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765878","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}

This review provide a comprehensive picture of the phytochemical and biological activities characteristics of Genipa americana L. deal with its ethnomedicinal use and botany based on literature reports. These researches pointed out a range of secondary metabolites with iridoids being the most prevalent and abundant. Until now, the biological tests have shown important pharmacological activities, especially the antioxidant, insecticide and antibacterial activities. Besides presenting itself in a very promising way in other areas such as food and cosmetics industry, it is also used in popular medicine to treat several diseases having this potential use disseminated in its various parts.

Samples were collected from December 2021 to May 2022. In total, 263 blood samples were collected from the patients who visited Bahawalpur Victoria Hospital, Bahawalpur Pakistan. A rapid diagnostic test (ICT) was used to diagnose Hepatitis B surface antigen and anti-HCV, followed by an enzyme-linked immunosorbent assay (ELISA). The data were analyzed using IBM SPSS version 22. In total, 263 samples were tested; 5.3% (14/263) tested positive for HBV, 25.4% (67/263) tested positive for HCV, and 0.76% (2/263) were co-infected.

To do this, the search for articles was done in three different databases, Science Direct, Springer Nature and Google Scholar, using the following descriptors: plant growth promoting bacteria, plant hormones, biological control, photosynthesis and abiotic stress. After selection, the included articles were systematized in the Excel program. Pearson Correlation and Principal Component Analysis were used for comparative analysis of physiological variables. 81 articles were included in the review, where a beneficial association was observed in 45 plant species distributed in 13 Orders and 13 Families, with emphasis on the Families Poaceae, Fabaceae, Solanaceae and Brassicaceae. 47 genera and 98 bacterial species were verified, where Bacillus and Pseudomonas represented 52% of the verified strains, with emphasis on Bacillus subtilis and Pseudomonas fluorescens. The main applications were growth promotion, productivity, control of biotic stress and abiotic stress. Positive regulation of photosynthesis was observed, modulating the gene expression of photosynthetic apparatus proteins, pigments, antioxidant production, increased hormonal and nutritional production, osmolyte content, antimicrobial production and decreased lipid peroxidation. Based on this review, it was possible to understand the multifaceted role of plant growth-promoting bacteria in contributing to the better direction of technology in agriculture.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e287279"},"PeriodicalIF":0.0,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143712154","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}
