{"title":"A Gecko-eye View of Naturalistic Enclosures","authors":"Davies Victoria, Heaman Abigail, Brereton James","doi":"10.29328/journal.ibm.1001026","DOIUrl":"https://doi.org/10.29328/journal.ibm.1001026","url":null,"abstract":"Naturalistic enclosures have become a popular exhibition technique for zoos, and reptiles and amphibians are regularly housed in these exhibits. While a considerable sum of research indicates that visitors prefer naturalistic exhibits, there are fewer studies documenting the behaviour and welfare of animals housed under these conditions. This study investigated the impact of a naturalistic enclosure on the behaviour of the turquoise dwarf gecko (Lygodactylus williamsi), and the welfare perceptions of visitors. When kept under naturalistic enclosures, dwarf geckos were seen to bask (p = 0.022), and engage in inactive behaviours (p = 0.001) significantly less frequently. A non-significant decrease was also seen in locomotion | (p = 0.074). While time spent hidden remains a confounding factor for behavioural analysis, the study indicates that when provided with hiding opportunities, L. williamsi may spend a considerable amount of time hidden from the public. Questionnaire analysis revealed that 84.6% of individuals believed that naturalistic enclosures demonstrated better welfare. Additionally, individuals who had previously owned a reptile were more likely to identify that areas to hide, enrich, and mimic the natural environment were important aspects of enclosure design. While the actual benefits of naturalistic enclosure design cannot be fully addressed by this study, this work suggests that visitors tend to inherently believe that naturalistic enclosures facilitate better welfare, even if they are not aware of the natural environment of the species being housed. This requires keepers to consider both aspects of functionality and enclosure relevance when designing exhibits for herptiles.","PeriodicalId":128593,"journal":{"name":"Insights in Biology and Medicine","volume":"84 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139016189","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}

{"title":"IC87201, a PSD-95/nNOS Inhibitor, Ameliorates Heart Rate Variability in the Rat Model of Middle Cerebral Artery Occlusion","authors":"Mohammadian Maryam, Bahaoddini Aminollah","doi":"10.29328/journal.ibm.1001024","DOIUrl":"https://doi.org/10.29328/journal.ibm.1001024","url":null,"abstract":"Objective: Assessment of heart rate variability (HRV) is a non-invasive and reliable method to evaluate autonomic disorders after cerebral ischemia. The present study was conducted to investigate the therapeutic potential of IC87201 in reducing post-stroke cardiac dysfunction. Materials and methods: Cerebral ischemia was induced by the middle cerebral artery occlusion (MCAO) method in 15 anesthetized adult male rats in three MCAO, MCAO+ DXM, and MCAO+ IC87201 groups, for one hour. Electrocardiogram was recorded before, and 48 hours after ischemia and drug administration, and HRV parameters were calculated from R-R intervals. In the treatment groups, IC87201 and Dextromethorphan hydrobromide monohydrate (DXM) were injected after an ischemic period. Results: After brain ischemia, the R-R interval decreased and consequently heart rate increased. The R-R intervals were used to extract the HRV frequency and time domains, including normalized low frequency (LF), high frequency (HF), LF/HF ratio, and standard deviation of R-R interval (SDRR). Normalized LF and LF/HF ratio enhanced 48 hours after ischemia, while normalized HF and SDRR significantly reduced compared to the pre-ischemic state. All HRV parameters had returned to their pre-ischemic level 48 hours after IC87201 and DXM administration, except SDRR, which recovered only in the IC87201 administered group. Conclusion: Based on our findings, it can be concluded that cerebral ischemia significantly worsens HRV parameters as a result of sympathetic overactivity. These changes were reversed by administering DXM and IC87201, but IC87201 has generally been more effective in lowering lesions. As a result, IC87201 can be introduced as an effective substance for the treatment of post-ischemic cardiac side effects.","PeriodicalId":128593,"journal":{"name":"Insights in Biology and Medicine","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131378923","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}

Objectives: To evaluate the composition of Dead Sea Salt and assess its in vitro cytotoxicity, and efficacy against oral bacterial leukotoxins, oral endotoxins and oral glucan sucrase. Methods: The cytotoxicity was evaluated in an established cell line (solution at 5000 µg/mL of culture medium) using positive and negative control groups. The effect on oral bacterial leukotoxin (LtxA) and different concentrations of lipopolysaccharide and glucan sucrase was established at 24, 36, 48, 60, 72, 84, and 96 hours using the HPLC method (high-performance liquid chromatography). Results: The most predominant elements detected were the water of crystallization (H2O, water that is found in the crystalline framework of salt and which is not directly bonded ), magnesium chloride (MgCl2), potassium chloride (KCl), sodium chloride (NaCl), calcium chloride (CaCl2), bromide (Br -) and sulfates (SO4). In vitro, Dead Sea Salt presented no cytotoxicity and was highly effective against leukotoxin, endotoxin, and glucan sucrase enzyme.

Anthelmintics are categorized into groups depending on the basis of their identical chemical structure and mode of action. Thiabendazole, mebendazole, and albendazole belong to benzimidazoles group of antihelmenthic medicines. From benzimidazoles group of antihelmenthic, thiabendazole was first discovered in 1961 and already a mentioned number of more benzamidazoles were interpolated as wide spectrum anthelmintics. Praziquantel has a particular effect on the enveloping layer of trematodes and increases permeability of calcium ion influx leading to uncontrolled muscle contraction and paralysis. Praziquantel has a particular toxic effect on schistosome parasites, where its mode of action has been resulted more extensively than in cestodes.

Zinc oxide nanoparticles (ZnO NPs) are used in biomedical applications and consumer products. ZnO-NPs are protected cell membranes against oxidative damage, decrease free radicals and malondialdehyde (MDA) levels, and increase the antioxidant enzyme levels. Objectives: The present aimed to evaluate the ameliorative effect of Zn-O nano-particles on oxidative damage and disturbance in the antioxidant defense system induced by cyclophosphamide in male albino rats. Materials and Methods: 24 adult male albino rats were randomly divided into 4 groups (6 rats of each). Group I (Control group): Received 0.2 ml saline /day i.p. injection for 14 days (day by day), group II, (nZnO group): Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, Group III (CP group): Received CP (20 mg/kg/day) b.w, day by day for 14 days by intraperitoneal injection, Group IV (CP + ZnO NPs group): Received nZnO group: Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, plus CP (20 mg/kg/day) b.w., day by day for 14 days by intraperitoneal injection. After 24-hr from the last treatment, all animals were anesthetized using light ether. Blood, lungs, and liver samples were taken and prepared for biochemical measurements. Results: Individual treatment of zinc oxide nanoparticles and CP induced liver cytochrome b5, cytochrome C reductase, and glutathione S-transferase (GST) compared to the control group, while CP increased P450. The combination of nZnO and CP prevents the elevation of cytochrome b5, P450, cytochrome C reductase, and GST compared with the CP treated group. Zinc oxide nanoparticles and CP increased liver thiobarbituric acid reactive substances (TBARS). The combination of nZnO and CP prevents the changes in TBARS concentrations compared with the CP. Injection of CP to rats reduced the activities of serum glutathione reductase (GR) and catalase (CAT) as compared with the control group. However, combination treatment of rats with nZnO and CP increased the activities of these enzymes compared with those treated with CP alone. Zinc oxide nanoparticles and CP increased serum and lung TBARS, while decreased glutathione (GSH) concentration compared to the control group, with more pronounced changes by CP. The combination of nZnO and CP prevents the changes in TBARS and GSH concentrations compared with the CP. Conclusion: It can be concluded that CP induced oxidative stress and disturbance in the antioxidant defense system. Treatment of rats with zinc oxide nano-particles and CP together attenuated the oxidative damage and disturbance in the antioxidant defense system induced by CP.
