To this end, we collected soil and leaf litter samples from 152 sample plots divided in physiognomies regionally called as Cordilheira, Capão, Murundu, Corixo and Cambará/Canjiqueira forest. In the laboratory, analytical determinations were conducted for 22 soil attributes and 11 elements of the chemical composition of the leaf litter. The forest communities showed a great well-defined edaphic gradient encompassing environments with high natural fertility soils (Capão and Cordilheira Abobral/Miranda), acidic soils with a high proportion of soluble Al3+ (Cambará/Canjiqueira, and Corixo), and poorly developed soils with a predominantly sandy texture (Nhecolândia region, Cordilheira and Murundu). Soil attributes are significantly related to the chemical composition of litter, as indicated by correlations between N, P, Ca, Mg, Mn and the C/N ratio with physical, chemical and soil organic matter attributes. This study revealed the interaction of soils with the chemical composition of litter, constituting an ecosystem service, in forest communities in the Brazilian Pantanal.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 suppl 3","pages":"e20240709"},"PeriodicalIF":1.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142779394","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 physicochemical analysis of xylan included the determination of monosaccharides, elemental composition, FTIR analysis, 2D nuclear magnetic resonance spectroscopy, and the determination of molecular weight. Xylan had an extraction yield of 28.44% and an elemental composition of 35.03% carbon, 5.65% hydrogen, and 59.32% oxygen. FTIR analysis revealed similarities between Dinizia excelsa xylan and commercial xylan. 2D NMR analysis confirmed the presence of characteristic xylan groups. Furthermore, xylan has a low molecular weight. In vitro cytotoxicity tests demonstrated low toxicity, indicating its potential for biological applications. Immunomodulatory activity assays revealed that xylan stimulated cell proliferation and the production of anti-inflammatory cytokines. The anticoagulant activity of xylan was low compared to heparin. The antioxidant activity of xylan was weaker compared to ascorbic acid and butylated hydroxytoluene (BHT). These results indicate that xylan from Dinizia excelsa has potential for several biomedical applications due to its immunomodulatory and anticoagulant properties.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 suppl 3","pages":"e20240219"},"PeriodicalIF":1.1,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142779419","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}

Three melissopalynological protocols were applied to the samples using alcian blue dye, basic fuchsin, and the traditional acetolysis methodology without dye. After preparing the pollen samples, and analyzing them under an optical microscope, six botanical families were recorded, e.g., Amaranthaceae, Asteraceae, Bignoniaceae, Fabaceae, Malvaceae, and Myrtaceae. The methodologies investigated proved to be efficient for detecting pollen structures and identifying botanical families thereof. The alcian blue dye-based protocol allowed a greater separation and discrimination of pollen grains as compared to the basic fuchsin and acetolysis ones, where pollen conglomerates were often identified. Even though acetolysis has been the most used method in melissopalynological studies, it has been claimed to offer risks to users due to the manipulation of corrosive and toxic solvents (i.e., H2SO4), also being lesser cost-effective and more time-consuming. Thus, considering the cost-effectiveness, the alcian blue dye and basic fuchsin-based methods seem to be preferred, being as efficient as acetolysis for identifying pollen grains.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 suppl 3","pages":"e20230703"},"PeriodicalIF":1.1,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142738115","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}
