This study assessed the susceptibility of six pitaya genotypes (S. undatus, S. polyrhizus, S. undatus subsp. lithocarpus, S. megalanthus, S. setaceus, and S. megalanthus × S. costaricensis 'Orange') to Meloidogyne incognita and M. javanica. The experiment was conducted in a completely randomized design with 20 replicates. The total numbers of eggs and second-stage juveniles (J2), as well as eggs and J2 per gram of root, were used to calculate the reproduction factor and reproduction index. Plant assessments included measurements of shoot and root fresh weights. The pitaya genotypes S. undatus, S. polyrhizus, S. undatus subsp. lithocarpus, S. megalanthus, S. setaceus, and S. megalanthus × S. costaricensis 'Orange' were classified as susceptible to M. incognita and M. javanica, as their reproduction factors exceeded 1.

The aim of this study was to carry out a systematic literature review focused on the detection of Escherichia coli in meat. The review covered studies published between 2021 and 2024, in English, Spanish and Portuguese. Data collection was carried out through CAPES Electronic Journals, using three databases: Scopus, Virtual Health Library (BIREME) and Web of Science. Initially, 149 articles were identified, of which 34 were excluded due to duplication in the databases. Thus, 115 articles were selected for the reading of titles and abstracts, resulting in the exclusion of 79 articles that did not meet the inclusion criteria. This left 36 articles for eligibility assessment, 20 of which were excluded because they did not specifically detect E. coli in meat. Finally, 16 articles were included in the review. The results reveal a significant prevalence of E. coli in meat products, highlighting the need for strict sanitary control practices throughout the production chain, from animal husbandry to final meat processing. The analysis also indicates that chicken and beef have a higher incidence of E. coli compared to pork and fish, underlining the importance of specific monitoring for these types of meat.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e292127"},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144227702","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}

Elucidating the chemical signals involved in the communication of this species is essential for finding new control alternatives. Therefore, the aim of this study was to determine whether chemical signals are involved in the mating process of M. spectabilis. In the first trial, the insect's behavior was evaluated in cages with male: female ratios of 4:1 and 1:4. As soon as copulation began, the behavior of males or females around the copulating couple was recorded. In subsequent trials, the olfactory responses of males and females of M. spectabilis were evaluated in a Y-shaped olfactometer for volatiles released by males, females and mating pairs. At a male: female ratio of 4:1, there were significantly more touches by the other males of the copulating couple. The number of individuals attached to the copulating couple and the copulation time did not differ significantly in relation to the male: female ratio used. The attractiveness of males to copulating pairs was also observed in the olfactometry test, in which males were significantly attracted only to copulating pairs and to the extract of copulating pairs. The females showed no olfactory attraction to any of the odor sources offered. This shows that chemical signals are involved in the mating process of M. spectabilis.","PeriodicalId":55326,"journal":{"name":"Brazilian Journal of Biology","volume":"85 ","pages":"e291452"},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144175864","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}

Thirty-six adult female Wistar rats were randomly assigned to 6 groups: control group, NaNO2 group (50 mg/kg BW), NaNO2+ TCSA-1 (50 mg/kg NaNO2 and 0.016 mg/kg BW TCSA), NaNO2+ TCSA-10 (50 mg/kg NaNO2 and 0.16 mg/kg BW TCSA), NaNO2+ TCSA-100 (50 mg/kg NaNO2 and 1,6 mg/kg BW TCSA), and NaNO2+ Fe (positive control group, 50 mg/kg NaNO2 and iron/ Fe supplement). Over 30 days, the haematological and liver function were assessed from blood samples. Exposure to NaNO2 resulted in significant reductions in packed cell volume (PCV), haemoglobin (Hb) concentration, and red blood cell (RBC) count, alongside elevated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea, and gamma-glutamyl transferase (γ-GT). TCSA had a therapeutic benefit in NaNO2-induced rats comparable to iron supplementation. The antioxidant properties of chlorophyll in the tablets markedly reduce the oxidative damage caused by NaNO2.
