Stress caused an increase in the hematocrit of tambaqui at IAE, with reduction after 48hAE. For glycemia, there were differences between the fish groups and collections with higher values for tambatinga and after IAE and 1hAE. Cholesterol in tambaqui increased after 24hAE and 48hAE, decreasing in hybrid after 24hAE with return to basal after 48hAE. SOD increased in IAE while in tambaqui the response only occurred after 48hAE, resulting in an increase in lipid peroxidation.

It causes buffalo reproduction failure, restricts the full exploitation of buffalo for milk and meat and down turning of the national economy of agricultural countries. Post-partum anestrus is one of the most ignored factors influenced by farm environmental conditions and genetic complement of animal. In the present study, we have tried to get an insight into genetic predisposition of anestrus by characterization of MEPA1 gene which decreases serum Igf-1 concentration during port partum stage. Sequences of MEPA1 gene retrieved from Ensembl database were analyzed by EXPASY, GeneMANIA, SIFT, I-Mutant, PROTPARAM, CELLO2GO, HOPE server, PHYRE2, SOPMA and SOSUI. SNPs reported in cases 19-23 were found to alter localization of protein. SNPs documented in cases 3, 4, 10, 14, 16, 19 and 23 affected topology.

Different biomedical research fields have different methodologies and therefore different forms of data representation. To understand whether there are distinct patterns of data representation, we analyzed how results are displayed in scientific publications from six fields: Biochemistry and Cell Biology, Bioinformatics and Computational Biology, Clinical Sciences, Oncology and Carcinogenesis, Pharmacology and Pharmaceutical Sciences, and Zoology. Our results show that Graphics were the most frequent type of representation, followed by Schemes and diagrams. Microscopy was the third most used type of image in most fields, except in Pharmacology and Pharmaceutical Sciences, where Molecules and chemical reactions were the third most frequent. Interestingly, each research field has a characteristic pattern of image. We further classified the image types in primary or secondary data, according to the level of human interference in its construction. Each field has a particular proportion of primary and secondary images. We also analyzed the frequency of words and observed a remarkable vocabulary difference between fields. The most frequent word of each field nicely correlates with the unique type of figures used.

Adult individuals were collected in wood fragments, identified, selected, and sectioned to obtain two protein extracts: one sample contains the entire exoskeleton. The other contains only the abdominal portion of the termites. The extract obtained exclusively from the termite abdomen (ABE) presented the highest concentration of proteins (670 mg/mL) compared to the crude extract of whole termites (EWT) (495 mg/mL) and the extract of the fungus Trichoderma viride isolated from termites (TvE) (397 mg/mL). All extracts showed enzymatic activities of total cellulase, endoglucanase, and exoglucanase. However, TvE showed the highest activities for all kinds of enzymes. Although the cellulolytic activities of the crude termite extracts were relatively low, they were measurable and stable. This stability permits their use in screening potential natural termiticides.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 1","pages":"e20240780"},"PeriodicalIF":1.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study evaluated 50 arabica coffee samples, 16 of which were natural process, and 34 were pulped coffes. These samples were originated from growing areas located in different altitude ranges and regions of the municipality, with similar planting spacing and predominance of Catuai cultivars. The samples were subjected to sensory analysis, which revealed that 58% of the samples were classified as specialty coffees: 3 natural, and 26 pulped coffes. Multiple correspondence analysis showed that average spectral indices, normalized difference vegetation index (NDVI), enhanced vegetation index (EVI), and photochemical reflectance index (PRI), derived from images of the multispectral instrument (MSI), were not associated with the quality parameters of the coffee beverage. In contrast, the plant senescence reflectance index (PSRI) proved to be the relevant factor in the quality of the drink. In summary, the analysis of the relationship between the indices demonstrated that the NDVI, which measures the vegetative vigor of plants, showed an inverse correlation with the PSRI. Additionally, the principal component analysis suggested that samples collected from drier areas differed significantly from other geographic regions.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 1","pages":"e20240921"},"PeriodicalIF":1.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological invasions are responsible for biodiversity loss, and are one of the possible consequences of water transfer projects. In addition, there is a possibility that the non-native species brings, at least in part, its parasite fauna to the invaded area, or acquire new parasites in the new environment. Here, we investigated the endoparasites of a non-native fish species that was recently recorded in the upper Paraíba River basin, Northeastern Brazil, after a major water transfer project. Fifty specimens of Moenkhausia costae were collected from the Poções reservoir, Monteiro municipality, Paraíba State. Forty-two hosts were parasitized (84%), and 179 parasite specimens were collected. The endoparasite community was composed of six species of nematodes. There was no significant correlation between parasitism and the size of the hosts, nor the host's condition factor. Although the size of parasitized and non-parasitized fish did not differ, the relative condition factor was significantly higher for parasitized fish. Future studies should investigate which parasites were introduced with M. costae, and which ones were part of the invaded environment.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"97 1","pages":"e20240651"},"PeriodicalIF":1.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we provide a comprehensive overview of the N5⁻ anion's potential as an energetic material, alongside the role of RMD simulations in elucidating its behavior. The ReaxFF forcefield was used to simulate the materials pyrolysis. The total energy behavior of different species containing pentazolate, across a range of temperatures (1500 K to 3000 K) revealed distinct trends and characteristics associated with the thermal dynamics and stability of the molecule under varying thermal conditions. Their mechanisms were elucidated, and the kinetic parameters were calculated, indicating that CNN5, with its low activation energy (39.14 kJ/mol), stands out as the most reactive, while PolyN5, with the highest activation energy (52.88 kJ/mol), is the most stable.
