Although LEVO’s role in modulating oxidative stress of cardiac cells has been studied, in the current study, LEVO was used, for the first time, to investigate its preventive and therapeutic roles in pancreatic islets through viability, functionality, and inflammation pathways as well as oxidative stress against the toxicity induced by sodium arsenite (NaAsO2). Following the optimization studies to select the proper concentrations of LEVO and NaAsO2, isolated pancreatic islets were exposed to different combinations of NaAsO2 and LEVO. MTT assay, glucose-dependent insulin secretion test, investigation of oxidative stress and inflammation biomarkers in addition to qualification of the expressions of P16, P38, and NF-κB genes were performed to assess different underlying mechanisms to investigate the protective role of LEVO against NaAsO2-induced toxicity. This study demonstrated that NaAsO2-treated pancreatic islets’ exposure to LEVO improved their viability and functionality while modulating the generation of oxidative stress and inflammatory biomarkers. Therefore LEVO caused significant recoveries in the characteristics of the islets. The main conclusion is that LEVO showed protective impacts in pancreatic islets against exposure to NaAsO2. However, therapeutic uses of LEVO in the field of diabetes need further investigations. HIGHLIGHTS Sodium arsenite is responsible for activating the oxidative stress and inflammation pathways in pancreatic islet cells and consequently decreasing their viability and function. Treatment of pancreatic islets with sodium arsenite results in the loss of glucose-dependent insulin secretion (GDIS) which can be alleviated by levosimendan. Levosimendan modulates the decreased level of secreted insulin by preventing formation of reactive oxygen species (ROS) and inactivating the inflammatory biomarkers. Levosimendan improves the viability and function of sodium arsenite-treated pancreatic islets by modulating insulin secretion and glucose control. Levosimendan acts as a protective agent against the toxicity induced by sodium arsenite in pancreatic islets through modulating the viability, oxidative stress, inflammation, and function pathways.

Botanical insecticides deemed promising alternatives in controlling this pest. In this study, extracts of Peganum harmala seeds, Pterocarya fraxinifolia leaves, and Tanacetum parthenium flowers were evaluated against S. oryzae adults. Phytochemical analyses showed that steroid, terpenoid, tannin, alkaloid, and flavonoid are present in the extracts. Bioassays revealed repellency effects of all extracts, besides, P. harmala extract exerted significant mortality (93.33 ± 6.6%, LC50: 521.06 mg/ml) hence it may have applications in preventing infestation of stored rice by S. oryzae. Highlights Plant extracts studied in this research efficiently repel rice weevil. These plant extracts show significant toxicity against rice weevil.

In 2021 a total of 2,942 snakebite patients were prospectively studied at four designated Health Facilities for Managing Snakebites (HFMS). The patients came from 94 Local Government Areas (LGAs) in 12 states in northern Nigeria. It was found that 435 (14.8%) patients actually accessed care within ≤2 hours of bite although 38.0% could have reached the HFMS within the time by car. In certain areas 92% of patients would have been able to reach a secondary or tertiary facility within ≤2 hours. Similarly, 437 (14.9%) patients traveled distances of ≤20 Km to reach a designated HFMS although 86% of patients resided within 5 Km of a road network. There was longer median delay to access care (15 hours), more patients (365) and higher proportion not treated with antivenom (22%) in August the wettest month of the year. Furthermore the patients who died (47) took a median time of 48 hours compared to 11 hours among known survivors (2,649) to access care. Expanding antivenom access to other secondary and tertiary HF in high burden areas especially during peak seasons will potentially improve the outcome among patients.","PeriodicalId":23211,"journal":{"name":"Toxin Reviews","volume":"42 1","pages":"537 - 547"},"PeriodicalIF":3.1,"publicationDate":"2023-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47719434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the origins of scorpions, we conducted a molecular phylogenetic study of the arthropod using slowly evolving enolase sequences. In this study, we used deep RNA-seq technology to identify the enolase sequences of Androctonus crassicauda and Hemiscorpius lepturus scorpions. The scorpion’s enolase sequences were in silico analyzed to predict the protein structures, physicochemical characterization, and exon-intron organization. The enolase of the scorpion was found to be a protein of 433 amino acids with a molecular mass of ∼47 kDa and an acidic isoelectric point. Here, we reported the existence of 8 exons and an inner GC/AG intron for scorpion enolase. Using homology modeling, the enolase of the scorpions was found to be very conservative during the evolution process. Furthermore, our phylogenetic analysis indicated the independent evolution of the Buthidae family from other scorpions and also the sister group relationship of Hemiscorpionidae with the Caraboctonidae families. The scorpions’ enolase sequences demonstrated a close fit to those of spiders, followed by mite counterparts. This strongly supports our phylogeny analysis, which indicates a sister-group relationship between scorpions and spiders and their common ancestors with mites. This study provided support for the pairing of scorpions with spiders, mites, etc. using enolase as a nuclear gene. Our molecular clock analyzes of the arthropod show that the most recent common ancestor of arachnids and insects were diversified in the Cryogenian period of Neoproterozoic era, earlier than dates reported from fossil records.","PeriodicalId":23211,"journal":{"name":"Toxin Reviews","volume":"42 1","pages":"228 - 241"},"PeriodicalIF":3.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46925667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples were collected during 2015 and 2017, on four pig farms in Serbia, and analyzed for elements by inductively coupled plasma mass spectrometry. According to the mean concentrations, the elements show the following trends: Fe > Mn > Zn > Cr > Ni > Cu > Cd > Se > As > Co in monocalcium phosphate, Zn > Mn > Fe > Cu > Co > Cr > Ni > Se > As > Cd in vitamin-mineral premixes, Fe > Zn > Mn > Cu > Ni > Cr > Se > Co > As > Cd in complete feed, and Fe > Zn > Mn > Cu > Ni > Cr > Co > Se > Cd > As in pig manure. The obtained results show that monocalcium phosphate and vitamin-mineral premixes are the main source of Mn, Zn, and Fe in complete feed mixtures. The Cd concentration in one sample of monocalcium phosphate exceeds the maximum permissible level. Only one out of six investigated complete feed mixtures was in accordance with the national and EU regulations.

After using MWFs in the metal processing, a polycyclic component with bore central groups was produced in on-used B fluid. DNA damage of on-used fluid with boron component occurred at a level lower than ethyl amine-containing fluid. Moreover, the genotoxicity of air samples in B fluid was higher than C airborne samples significantly. More careful management have to be considered for the replacement of amine corrosion inhibitors with boron-containing chemical in MWFs.

Thus, this study focused on developing a comprehensive review on the mechanism of STZ in inducing diabetogenic effects, insulin signaling dysfunction, neuroinflammation, oxidative stress, cerebral amyloid angiopathy, and cholinergic deficit in AD rodent models.
