Forensic science has a very important role in the crime scene. During the inspection of the crime scene, the concerned scientific officer carefully inspects various types of cases and collects evidence which is prima facie related to the crime scene. All the evidence obtained during the inspection is sent to the forensic laboratory in a sealed condition for physical, chemical, biological and electronic testing. After the test, it is assessed as per the report received that how the incident sent to the lab is related to the crime scene, how the evidence is related to the deceased or the victim, it helps in understanding and solving it in a systematic way. The presented research paper is related to such a case in which a girl dies in a road accident in District Balrampur, State Chhattisgarh, which prima facie appeared to be a normal road accident after seeing the crime scene, but when the investigation was done as per the instructions given by the senior scientific officer to the investigating officer, it emerged as a murder committed under a well-planned conspiracy. In this case, the doctor who conducted the postmortem also It was recommended to give the cause of death only after the forensic report came in. During the investigation of this case, the concerned person was traced and after collecting the evidence, the scene of crime was inspected again by the senior scientific officer and scientific officer of forensics and the evidence found during the inspection was sealed and sent to the forensic laboratory; the test report of which came as expected, so the case was resolved and the accused was punished. In the said case, the scene of crime inspection and the forensic test report of the evidence found at the scene of crime played a major role.

Background: Sampling time and containers used for sample collection are crucial preanalytical processes, dictating the accuracy and precision of lipid profile results. We compared the effect of sampling time and routine container on lipid profiles. Methods: This cross-sectional study was conducted among final-year students of the Department of Biochemistry at the Federal University Otuoke, Bayelsa State, in 2024. A total of 150 participants were recruited for this study. Fasting, starvation, and random blood samples were collected from each patient into plain containers, lithium heparin, K2EDTA, and fluoride oxalate containers simultaneously on daily staged structures. Samples in anticoagulant tubes were immediately centrifuged, and plasma was obtained while samples in plain containers were made to clot before centrifugation to obtain serum. The plasma and serum obtained were used to estimate the concentrations of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-c), and high-density lipoprotein (HDL-c) using an automated chemistry analyzer. Results: The study shows a significant mean increase (P<0.05) in TC and LDL concentrations in the fasting and starvation groups compared to the control and random samples. Similarly, the anticoagulants used revealed a significant mean increase (P>0.05) in the concentrations of TC and LDL in lithium heparin and fluoride oxalate compared to EDTA and plain containers. Furthermore, the findings revealed a significant increase in triacylglycerol concentration in the lipid diet group when compared to other groups, whereas other parameters were stable. Conclusions: Random sampling in lipid profile estimation could be more suitable for fasting or starvation sampling. In a similar vein, the suitability index of sample containers placed K2EDTA and plain containers as a better choice for lipid profile estimation, comparable to lithium heparin and fluoride oxalate.

Given that employees in petrochemical industries are exposed to various pollutants and are exposed to serious risks, the need for a comprehensive risk assessment program to determine hazardous chemicals that affect the health of exposed individuals and also to determine hazardous processes and tasks seems essential. Study Method: This cross–sectional–case study was conducted in 3 stages. The first stage included identifying hazardous substances and determining the risk factor of chemicals, the second stage included assessing exposure to benzene, and the third stage included estimating the relative risk of COVID–19 due to exposure to benzene through epidemiological studies. Findings: According to the risk assessment method, 40 chemicals were identified in the entire petrochemical company studied. Benzene was introduced as the most hazardous chemical. The results of the second stage showed that people in the main site during the noon shift and in the aromatic site with an average exposure of 4.29 ppm had the highest exposure to benzene. According to the results of the estimation stage of relative risk of COVID–19 in exposure to benzene, the highest relative risk in workers at my site was found to be related to workers in the aromatic unit, who had a cumulative exposure of 149.4 ppm–years (ppm–years) and a relative risk of 3.2. The statistical test result also showed that there was a significant relationship between the level of exposure to benzene and different work groups (P<0.001). Discussion and Conclusion: This study showed that benzene achieved a risk level of 5 with a risk coefficient of 4.5–5, indicating that corrective measures for this highly hazardous and carcinogenic chemical should be initiated as soon as possible. Schematic of the mechanism analysis and impact of the COVID–19 pandemic and outbreak on petrochemistry and petroleum mechanics.

Postural management is an essential part of treating cerebral palsy (CP), but research in this area, particularly in the Middle East, is limited. This study aimed to assess how selecting the right wheelchair can affect spasticity, quality of life, and motor function in children with CP. The study included 35 children, aged 4 to 12 years, all with moderate to severe motor impairments (GMFCS levels 3 to 5). After four weeks of postural management using properly selected wheelchairs, there was a significant reduction in spasticity, as seen in improvements across key joints like the shoulders, elbows, wrists, and hips (p < 0.001). There were also notable improvements in motor function, with GMFCS scores improving significantly (p < 0.001). Additionally, the children’s quality of life scores saw a marked increase, from 3083.9 ± 206.6 to 3538.6 ± 186.9 (p < 0.001). These findings stress the importance of choosing the correct wheelchair for children with CP, as it can make a significant difference in both physical function and overall well-being. The results also highlight how important postural management and occupational therapy are in improving the lives of children with CP.
