In this article, the current scenario of viscera handling in forensic science laboratories in India is mentioned in detail with a step-by-step procedure. Tests for phosphine and various pesticides are performed in the stomach and small intestine. Drugs are extracted according to different procedures depending upon the affinity of the drug i.e., acidic, basic, or neutral. After that, Tests for drugs and other toxic substances are usually performed in blood, liver, spleen, and kidney. Blood usually comes in the third jar, and is tested for drugs, alcohol, and maybe for pesticides, phosphine and for any other suspected toxin. Viscera sample needs to be digested before the analysis of heavy metals. Any part of the viscera can be digested and tested for heavy metal. Usually, a mixture of all the viscera parts is digested and analysed. The techniques mentioned in this article are rigorously used in the chemistry and toxicology division in forensic laboratories in India.","PeriodicalId":23205,"journal":{"name":"Toxicology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010279","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}

Ultrastructurally, the NE-CaNP were smooth, spherical with a tendency to agglomerate and evenly distributed. The NE-CaNP had a mean diameter of 231.4 ± 89.2 nm and zeta potential of -31.3mV. The mean coupling efficiency of CaNP was 90-91 %. The experimental trial consisted of control, NE-CaNP control, DMBA, DMBA+NE and DMBA+NE-CaNP groups. The mean latency periods for occurrence of mammary tumor were significantly (P ≤ 0.05) increased in the DMBA+NE and DMBA+NE-CaNP groups compared to the DMBA group. The mean latency period in the DMBA+NE-CaNP group was significantly (P ≤ 0.05) higher than the DMBA+NE group. The mean tumor frequency, volume and weight were significantly (P ≤ 0.05) decreased in the DMBA+NE-CaNP group. Histopathologically, the number of benign lesions was found highest (47.54%) in DMBA+NE-CaNP group rats. The relative percent reduction in malignancy as compared to the DMBA group was 42.86% and 54.29% in the DMBA+NE and DMBA+NE-CaNP groups respectively. In conclusion, the neem leaf extract loaded calcium phosphate nanoparticles were found to have better anti-carcinogenic potential by significantly reducing the incidence, frequency, weight, volume, malignancy and increased the tumor latency period of DMBA induced mammary tumors in female Sprague-Dawley rats as compared to rats treated with neem extract alone. Findings of the present study suggested that the neem leaf extract loaded calcium phosphate nanoparticles (NE-CaNP) has immense anticancer potential in terms of reduction in tumor burden and malignancy.","PeriodicalId":23205,"journal":{"name":"Toxicology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138979409","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}

In order to mitigate the adverse impacts of these heavy metals, it is imperative to reduce their concentrations in environmental samples. Therefore, this study aimed to produce zinc nanoparticles employing Diospyros chloroxylon (Roxb.) to effectively eliminate carcinogenic metals from water. The produced nanoparticles were subjected to comprehensive characterization using FT-IR, XRD, SEM, and EDX techniques. The XRD data indicated the emergence of a hexagonal wurtzite structure. SEM images illustrated the spherical morphology of the synthesized particles, with an average diameter measuring 53 nm and having elemental zinc accounting for 69.4% of the composition. The subsequent heavy metal sorption experiments encompassed a range of variables, remarkably, the nanoparticles displayed exceptional adsorption capabilities, achieving maximum removal rates of 95.81%, 90.13%, and 91.25% within an equilibrium time of 90 minutes for Cr, Pb, and Cd, respectively. The adsorption process adhered to a pseudo-first-order reaction kinetics model, with high correlation coefficients of 0.9561, 0.99058, and 0.98481, along with respective rate constants (K) of 0.483, 0.233, and 0.328 for Cr, Pb, and Cd.

Growing concerns towards individual well- being may however impede the widespread use of this intriguing invention. Although people are exposed to nanoparticles from an early age, but it has increased significantly in the past several years owing to anthropogenic sources of these nanoparticles. The consequences of nanoparticles on the male and female reproductive system are addressed in this review. NPs can infiltrate the epithelial barrier, placental barrier, and blood-testis-barrier and then amass in reproductive organs. NPs amassing impairs organs such as the testis, ovaries and uterus via obliterating Leydig cells, Sertoli cells and Germ Cells, exacerbating reproductive system impairment which unduly affects the quality, amount, morphology, and mobility of sperms or decreasing the amount of egg maturation and distress the folliculogenesis mainly primary and secondary follicular development. NPs may also alter secreted hormone levels and induce effects on sexual behavior. These detrimental effects correlate to nanoparticle composition, surface modification, dosage, mode of transmission and animal species. The current review, however, concentrates on nanoparticles induced toxicological issues and their potential toxicity mechanisms such as oxidative damage, apoptosis, inflammation as well as genotoxicity. NPs may enhance inflammatory response, and oxidative stress, and produce ROS damage, which leads to cytotoxicity at both molecular and genetic levels.","PeriodicalId":23205,"journal":{"name":"Toxicology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138978642","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}

Compared to other models of obesity, the progesterone-induced obesity model is more specific to the female population; it focuses on the eating behavior and behavioral and emotional changes associated with progesterone. We aimed to study the changes in feeding behavior upon progesterone administration and the effects of Myrica nagi Thunb (Myricaceae) extracts on these changes. Further, this study aimed to provide insights into the progesterone-induced hyperphagia modulated by serotonergic and dopaminergic systems. In this study, experimental obesity was induced in female mice by treating with a high dose of progesterone for 28 days (sub-chronic study) followed by the assessment of parameters such as food consumption behavior, behavioral parameters including ambulatory movements, rearing, and grooming, and biochemical parameters such as lipid profile (total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein), liver parameters (alkaline phosphatase and serum glutamic pyruvic transaminase), serotonin and dopamine levels, and liver histopathology. The sub-chronic administration of progesterone, via the subcutaneous route, induced significant hyperphagia and promoted fat accumulation. Even though we did not find significant differences in food intake between mice in the control group and progesterone-treated groups, the final weight in the progesterone-administered groups increased, signifying the impact of this progesterone-induced obesity model. Treatment with MEMN extract reversed the progesterone-induced effects suggesting that herbal extracts can be exploited as serotonergic and dopaminergic agents for the treatment of progesterone-induced eating disorders, especially in the female population.","PeriodicalId":23205,"journal":{"name":"Toxicology International","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139254255","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}
