This experimental analytical study develops an analytical method and evaluates the performance of square wave anodic stripping voltammetry (SWASV) for the quantification of mercury in urine. For this purpose, the operating conditions of the SWASV system were optimized through tests with standard mercury solutions. Commercial urine (BIO-RAD®) pretreated with nitric acid was used. Linearity, precision, trueness, limit of detection (LOD), and limit of quantification (LOQ) were evaluated. The results showed high precision, with a relative standard deviation (%RSD) of 6.21. Furthermore, the trueness analysis revealed no significant differences between SWASV and the cold vapor atomic absorption (CVAA) method, p = 0.2601. The LOD and LOQ were 0.68 and 2.2 μg L-1, respectively. These findings suggest that SWASV is a precise method comparable to CVAA for the detection of mercury in urine under controlled laboratory conditions. Additional studies are required to evaluate its applicability in real population biomonitoring scenarios.","PeriodicalId":53651,"journal":{"name":"Revista Peruana de Medicina de Experimental y Salud Publica","volume":"43 1","pages":"77-82"},"PeriodicalIF":1.1,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13245983/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148426301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anti-inflammatory activity was determined through heat-induced ovalbumin denaturation and hypotonicity-induced hemolysis assays.Results: The extract showed high antioxidant activity in both the DPPH●radical scavenging assay (747.6 mg Trolox equivalents/gram of dry extract) and the FRAP assay (435.9 mg FeSO4 equivalents/gram of dry extract). The extract (50 to 1000 μg/mL) inhibited lipid peroxidation, H2O2-induced hemolysis, and ovalbumin denaturation. No activity was observed in the hypotonicity-induced hemolysis assay. TPC and TFC were 642.7 mg gallic acid equivalents/gram and 416.2 mg catechin equivalents/gram of dry extract, respectively.Conclusions: These activities were reported for the first time for A. colubrina from northern Peru, suggesting that the hydroethanolic extract of A. colubrina bark possesses significant preliminary in vitro antioxidant and anti-inflammatory properties and that the high polyphenol and flavonoid contents may be responsible, at least partially, for these activities.","PeriodicalId":53651,"journal":{"name":"Revista Peruana de Medicina de Experimental y Salud Publica","volume":"43 1","pages":"51-60"},"PeriodicalIF":1.1,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13245994/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148426368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

District altitude of residence was categorized into four groups (0-500; 501-2,000; 2,001-3,500; and ≥3,501 masl). The outcome was death from COVID-19 according to the official death registry. Poisson regression was used to estimate adjusted relative risks for individual and contextual variables, using robust variance clustered by district. The analyses were repeated according to the five epidemic waves that occurred between March 2020 and December 2022.Results: A non-linear association was observed between the altitude of residence and death from COVID-19, consistent with a \"U-shaped\" pattern, characterized by a lower risk of death in cases residing between 2,001 and 3,500 masl compared to those residing between 0 and 500 masl. This pattern remained consistent in the analyses stratified by epidemic wave.Conclusions: In Peru, during the 2020-2022 period, the data do not support a monotonic decrease in the risk of death from COVID-19 with increasing altitude of residence.
