This study aims to identify priority basins for conservation of threatened, near-threatened, and restricted-range endemic freshwater fish species in the Northeastern Mata Atlântica freshwater ecoregion, highlighting irreplaceable and critical locations for conservation and impact mitigation. Through spatial prioritization, three scenarios with distinct conservation features were considered: (a) 35 threatened species, (b) 118 near-threatened and restricted-range species, and (c) all 153 species. A total of 50 and 89 basins were prioritized in the first two scenarios, respectively, and 135 basins in the third scenario, with 36 classified as critical due to environmental stressors, particularly in the Rio Doce basin. Our results suggest that the current protected area network is insufficient for safeguarding most target fish species. This study presents an initial framework for prioritizing areas that can provide a basis for further, more refined assessments and to support conservation policies such as national or regional action plans, protecting basins and species.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 1","pages":"e20240731"},"PeriodicalIF":1.1,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147760051","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 aim of this study was to evaluate key laboratory findings in the assessment of renal function in dogs with a suspected diagnosis of IMHA and to correlate these findings with disease prognosis. A prospective study was conducted on 21 dogs treated at a veterinary hospital with a suspected diagnosis of IMHA. Blood samples were collected for complete blood count and biochemical analyses, and urinalysis was performed. Significant alterations in renal function were observed in IMHA patients. The urinary protein-to-creatinine ratio (UPC) was elevated compared to controls (P < 0.0002) and correlated with the degree of anemia (R = -0.638) and the inflammatory status, assessed by white blood cell count (R = 0.550). In addition, urinary bilirubin levels were increased in IMHA patients (P < 0.0001), suggesting that bilirubin is an important prognostic marker of the disease. Renal function is impaired in IMHA patients, and urinary bilirubin levels serve as a valuable prognostic indicator.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 1","pages":"e20241141"},"PeriodicalIF":1.1,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147759981","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}

Numerous strategies are applied to remediate oil-contaminated sites, and each scenario contributes to assessing the maximum efficiency of available cleanup approaches. This study evaluated, on a laboratory scale, the effect of phenazine methosulfate (PMS) on Waste Lubricating Oil (WLO) removal by P. aeruginosa. Microcosms were contaminated with WLO containing 448,000 mg·kg⁻¹ of TPH. WLO: aqueous phase ratios of 1:40, 1:20, and 1:10 were tested, all supplemented with PMS at 5 µg·mL⁻¹. After 20 days of incubation at 29°C, greater WLO removal was observed in microcosms without PMS (33.8-37.8%), whereas PMS-amended systems removed only 9.9-15.3% (p > 0.05) possibly due to WLO composition or PMS interacting with alternative cell pathways. In both treatments, the inoculated cells were not adversely affected by the stressful conditions and established stable biofilms. This is the first report describing the effect of PMS on P. aeruginosa biofilm formation during WLO biodegradation under recent-contamination conditions. These findings indicate that combining bioaugmentation with exogenous phenazine addition should be avoided in the initial treatment phase.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"98 1","pages":"e20250706"},"PeriodicalIF":1.1,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147760043","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}

Food consumption and dietary acceptance were also evaluated. A ROC curve assessed the ESS's capacity to predict supplement usage. Findings revealed a significant association between NRS-2002 scores, indicating nutritional risk, and daytime sleepiness, as measured by the ESS. However, hospital length of stay did not correlate significantly. The ESS demonstrated potential as a screening tool for supplementation, with a cutoff of 10 points (sensitivity: 76%; specificity: 60%). These results suggest a correlation between sleepiness and food intake in cancer patients, emphasizing the necessity for holistic interventions.

Bioinformatic tools, including SIFT, PolyPhen, SNPs&GO, Panther, PhD-SNP, SNAP2, I-mutant, and I-TASSER, were utilized for insilico analyses. Genotypes and allele frequencies were determined by real-time PCR. Odds ratios (OR) and 95% confidence intervals assessed association strength. In silico results indicated the conversion of MnSOD Val16Ala is tolerated; nevertheless, the I-mutant score suggested decreased protein stability. A significant statistical correlation was found in the allele positivity [OR:2.216, 95%CI:1.269-3.87, chi2:7.95, p:0.0048]. In the homozygous model, a significant difference was observed [OR:2.724, 95% CI:1.145-6.48, chi2:5.33 p: 0.021]. The results demonstrated that the rs4880 \"C\" allele significantly affected acne development [OR:1.701, chi2:7.62, p: 0.005].

We conducted seasonal field surveys assessing hydrochemistry, vegetation, birds, and reptiles, and compared our findings with existing literature. We recorded 18 bird species, including three flamingo species, six of which are classified as vulnerable or endangered, and confirmed a new record of the vulnerable reptile Liolaemus audituvelatus. Vegetation cover was sparse; Azorella compacta, a vulnerable species, was observed. Hydrochemical analysis showed predominance of chloride and chloride-sulfate water types, with elevated levels of B, As, and K. These hydrochemical conditions appear to influence the presence and distribution of sensitive species, particularly those dependent on wetlands and brine pools. The Salar functions as a crucial biological corridor for species of conservation concern. Our results underscore the urgent need for formal protection of this unique high-Andean ecosystem.

The evaluated parameters included color, transparency, puncture resistance, and water solubility. These were statistically analyzed using a CRD with three replications, followed by mean comparisons through Tukey's test. Biodegradability data were assessed and presented using qualitative descriptive methods. The findings revealed that bioplastic containing 4% INCES gelatin had the brightest, yellowish hue, the lowest transparency, the least puncture resistance, and the highest water solubility. Biodegradability tests showed that the bioplastic decomposed readily in soil within five days. In summary, bioplastic incorporating INCES gelatin displayed inadequate physical properties compared to other samples.

These aspects gain greater importance when evaluated together at the only UNESCO Mixed Heritage Site of Culture and Biodiversity in Brazil, Paraty and Ilha Grande. Thus, we examined the wood used in the construction of a 18th century warehouse on Ilha Grande. The identification of the samples began with the InsideWood database to generate preliminary taxa. Detailed anatomical comparisons were conducted using databases, literature, and reference collection. Species were selected for comparison based on anatomical similarity, commercial relevance, geographic distribution, and local floristic records. Seven different taxa were identified, six of which are compatible with the local formation of Atlantic Forest.
