Sensitivity and Intertextile variance of amylase paper for saliva detection


Contemporary forensic science hinges on DNA analysis to link an individual to a crime scene. Sources of DNA include bodily fluids, including saliva. Amylase is a primary enzyme in human saliva and thus, if detected, indicates possible presence of human saliva. Amylase paper can be used to map apparent saliva and thus provide a source from which DNA can be extracted and analyzed. In this study, the sensitivity of amylase paper was tested, firstly, using dilutions of an amylase standard and subsequently also tested using fresh human saliva. Three trials total were conducted, the first two using an amylase standard and a third using fresh saliva. The first two trials demonstrated firstly that detection of amylase is dependent on the material upon which amylase is deposited. The third trial demonstrated that amylase levels in human saliva may drop significantly somewhere around 48-72 hours. All trials were consistent in the concentration of amylase that Seratec Amylase Paper will detect.

A case of Pulmonary Tuberculosis complicated by Pulmonary Thromboembolism


We report a case of pulmonary embolism complicated with pulmonary tuberculosis. A 48-year-old woman suffered from pulmonary tuberculosis more than 6 years without formal treatment. Recently, she went to hospital because of “chest tightness and dyspnea”, and died in the process of admission to hospital. Pulmonary embolism was found by autopsy and histological examination. We analyzed the relationship between pulmonary tuberculosis and pulmonary thromboembolism and the problems we should pay attention to in forensic pathology.

Awareness level on the role of forensic DNA database in criminal investigation in Nigeria: A case study of Benin city


Pieces of evidence have continued to emerge, demonstrating the extensive efficiency and effectiveness of the DNA database in assisting criminal investigations around the world. Therefore, the present study aimed to determine the awareness level on the prominent role of Forensic DNA Database on Crime Investigation in Nigeria: a case study of Benin City. In conducting this research, a total of 458 questionnaires were distributed around Benin City between the periods of 12th January 2020 to 21st March 2020, with a particular focus on security agents and students. The questionnaire comprised of three main categories: Socio-demographic characteristics, Information about the National Forensic DNA Database, and Information about DNA evidence, and Nigeria Criminal Justice system. For the analysis of data collected; the statistical tool used was also Statistical Package for Social Sciences, version 22 for windows. Responses were compared using chi-square and presented as counts and percentages. In determining the level of awareness, the following responses were obtained. Of the total population: 53.28% had no idea about forensics, 19.21% were uncertain and 27.54% knew about forensics. The same trend was observed with Forensic DNA profiling, 42.14% did not know, 22.27% were uncertain and 35.59% demonstrated good knowledge of Forensic DNA profiling. On the knowledge about the National Forensic DNA Database, 48.47% had no knowledge, 22.27% were uncertain and 29.26% were knowledgeable about it. The result of the present study revealed that the awareness level of the forensic DNA Database was found to be inadequate.
