The plant species Cyperus rotundus L. (C. rotundus) belongs to the Family Cyperaceae, widely used in traditional Chinese medicine. Research has documented the cytotoxic capabilities of this species, suggesting that its chemical constituents could be potent against cell lines. To analyse the functional groups, present in Cyperus rotundus alcohollic extract (CRAE) using FTIR spectroscopy. To evaluate the cytotoxicity of CRAE using brine shrimp lethality test and cell lines. The alcoholic extract of C. rotundus dried powder was prepared. To identify functional groups and assess the chemical compo

The study utilized an exploratory qualitative method to gather data from polygamous/Bigamous women who agreed to an in-depth interview. It aimed to examine the cultural aesthetics caused by polygamy, the results, and the coping mechanisms employed by women to navigate to deal with co-wives’ relationships and their consequences. First, the causes behind polygamy were found to be mostly related to infertility or only having female children, husbands’ love marriages, pressure from the in-laws’ families, and a desire to preserve their marriage rather than end it. The second th

The DNATyper™ 21 amplification kit is a 5-dye multiplex assay, which is widely used in construction of the Chinese National autosomal DNA database. However, the DNATyper™ 21 kit has not been extensively used in forensic DNA casework. Therefore, this study aimed to elucidate the reliability of the DNATyper™ 21 kit compared with Verifiler™ Plus kit and to assess its applicability on forensic analysis. Standard DNA samples with concentrations of 0.031 25, 0.062 5, 0.125, 0.25, 0.5 and 1.0 ng/μL were used for sensitivity testing. DNATyper™ 21 kit and Verifiler&t

Choking is asphyxial death caused by a foreign body blocking the respiratory tract from the inside and obstructing the exchange of gas. In forensic pathology identification, choking is rare, and its identification is mainly based on the discovery of foreign bodies in the throat, trachea, bronchus and other parts of the deceased during autopsy, which can be food, such as lumps, or non-food. There have been previous reports of cases of choking caused by mistakenly swallowing balloons. The similarity with this case is that foreign bodies may have one-way valve effect, but the difference is tha

The aim of this study was to establish a comprehensive forensic reference for calculating likelihood ratios of different genetic relationships in the Chinese Han population. To achieve this, frequency parameters for 36 X-STR loci were determined. A notable limitation of previous literature reports was their reliance on small sample sizes, typically consisting of only 200-300 individuals. In contrast, our analysis incorporated data from over 1000 individuals sourced from 16 literature references, thereby ensuring a more robust and representative sample. The obtained allele frequency data for
