Intrapuparial stage aging and PMI estimation based on the developmental transcriptomes of forensically important (Diptera: Calliphoridae) gene expression.

Background: The expression profiles of differentially expressed genes (DEGs) during pupal development have been demonstrated to be vital in age estimation of forensic entomological study. Here, using forensically important (Diptera: Calliphoridae), we aimed to explore the potential of intrapuparial stage aging and postmortem interval (PMI) estimation based on characterization of successive developmental transcriptomes and gene expression patterns.

Methods: We collected pupae at 11 successive intrapuparial stages at 20 °C and used the RNA-seq technique to build the transcriptome profiles of their intrapuparial stages.

HOFE: an interactive forensic entomological database.

The significance of entomological evidence in inferring the time, location and cause of death has been demonstrated both theoretically and practically. With the advancement of sequencing technologies, reports have emerged on necrophagous insects' nuclear genomes, transcriptomes, proteomes and mitochondrial genomes. However, within the field of forensic entomology, there is currently no available database that can integrate, store and share the resources of necrophagous insects.

Improved Glass Bead-Vortex Oscillation Method for DNA Extraction from Diatom.

Objectives: To examine the effect of improving diatom DNA extraction by glass bead - vortex oscillation method.

Methods: The DNeasy PowerSoil Pro kit was used as control, two plant DNA extraction kits with different principles (New Plant genomic DNA extraction kit and Plant DNA Isolation kit) and one whole blood DNA extraction kit (whole blood genomic DNA extraction kit) were selected to extract diatom DNA from lung tissue and water sample of the same drowning case. The combination of mass ratio of glass beads with different sizes and vortex oscillation time was designed, and the optimal DNA extraction conditions were selected with the addition of glass beads oscillation.

Temporal Expression Profiles Reveal Potential Targets during Postembryonic Development of Forensically Important (Diptera: Sarcophagidae).

(Robineau-Desvoidy, 1830) is a species of medical and forensic importance. In order to investigate the molecular mechanism during postembryonic development and identify specific genes that may serve as potential targets, transcriptome analysis was used to investigate its gene expression dynamics from the larval to pupal stages, based on our previous -assembled genome of . Totals of 2457, 3656, 3764, and 2554 differentially expressed genes were identified.

Characterized Gene Repertoires and Functional Gene Reference for Forensic Entomology: Genomic and Developmental Transcriptomic Analysis of Aldrichina grahami (Diptera: Calliphoridae).

Many flies of Diptera are common entomological evidence employed in forensic investigation. Exploring the existence of inter- and intra-species genomic differences of forensically relevant insects is of great importance. Aldrichina grahami is a common blow fly species of forensic importance.

The complete mitochondrial genome of (Diptera: Sarcophagidae).

Chao & Zhang, 1988 (Diptera: Sarcophagidae) is considered to be of ecological and medical significance. In this study, we report the mitochondrial genome (mitogenome) of . This mitogenome was composed of 15,936 bp in length (GenBank accession no.

Comparative analysis of mitochondrial genomes among the subfamily Sarcophaginae (Diptera: Sarcophagidae) and phylogenetic implications.

The subfamily Sarcophaginae is extremely diverse in morphology, habit and geographical distribution, and usually considered to be of significant ecological, medical, and forensic significance. In the present study, 18 mitochondrial genomes (mitogenomes) of sarcophagid flies were first obtained. The rearrangement and orientation of genes were identical with that of ancestral insects.

The evaluation of forensic characteristics and the phylogenetic analysis of the Ong Be language-speaking population based on Y-STR.

The Ong Be language, an important branch of the Tai-Kadai language family, is one of the most distinctive languages on Hainan Island. Ong Be language speakers, who have lived in the Lingao district of Hainan Island for generations, were classified as Han Chinese in the early days of the establishment of the People's Republic of China but have distinct differences from the Han Chinese in language, lifestyle, customs and values and particularly in appearances and features. Currently, Y-chromosomal short tandem repeat (STR) haplotypes have been widely used in genetic applications, such as human forensics, historical investigations and genealogical research.

Critical role of insulin‑like growth factor binding protein‑5 in methamphetamine‑induced apoptosis in cardiomyocytes.

Methamphetamine (MA) is a highly abused amphetamine‑like psychostimulant. At present, the mechanisms underlying MA‑induced cardiotoxicity are poorly understood. The cardiotoxic effects have yet not been clearly elucidated with respect to the apoptotic pathway.

Remodeling of ion channel expression may contribute to electrophysiological consequences caused by methamphetamine in vitro and in vivo.

Methamphetamine (MA) is a psychostimulant. MA may induce numerous cardiotoxic effects, leading to cardiac arrhythmias, heart failure, eventually leading to sudden cardiac death. The deleterious effects of methamphetamine work in tandem to disrupt the coordinated electrical activity of the heart and have been associated with life-threatening cardiac arrhythmias.
