The shear number of websites a vailable addressing the topic of forensic DNA investigation can make the search for specific information time-consuming and frustrating. This review aims to relieve this tension by drawing the reader's attention to a small number of well-produced and maintained websites covering major aspects of the forensic DNA field in genomic and Y chromosome short-tandem repeats and mitochondrial DNA analysis.

This study evaluated the effectiveness of the amplicon RX post-PCR clean-up kit in enhancing trace DNA profile recovery from forensic casework samples amplified using the GlobalFiler PCR amplification kit. The impact of post-PCR clean-up on allele recovery and signal intensity was assessed in both trace casework samples and control samples across a range of DNA concentrations. The results showed that the amplicon RX method significantly improved allele recovery compared to the 29-cycle protocol (p = 8.

Skeletal remains are the only source of the genetic material of decomposed organisms or once-lived species. Unlike, soft tissues they are highly mineralized, and their anatomical and morphological structure prevents their deformation in the presence of adverse environmental factors. Therefore, bones and teeth protect the Deoxyribonucleic Acid (DNA) inside them.

Traumatic brain injury (TBI) is identified as a risk factor for Parkinson's disease (PD), which is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN). However, the precise mechanism by which chronic TBI initiates PD pathogenesis is not yet fully understood. In our present study, we assessed the chronic progression and pathogenesis of PD-like behavior at different intervals in TBI mice.

Isothermal amplification-based nucleic acid detection technologies have become rapid and efficient tools for molecular diagnostics. Sequence-specific monitoring methods are crucial for isothermal amplification, as they help identify the occurrence of extended primer dimers, which can lead to false positive results. Fluorescent aptamers are promising tools for real-time monitoring of isothermal amplification but are inherently limited by thermostability.

The generation of forensic DNA profiles consisting of single nucleotide polymorphisms (SNPs) is now being facilitated by wider adoption of next-generation sequencing (NGS) methods in casework laboratories. At the same time, and in part because of this advance, there is an intense focus on the generation of SNP profiles from evidentiary specimens for so-called forensic or investigative genetic genealogy (FGG or IGG) applications. However, FGG methods are constrained by the algorithms for genealogical database searches, which were designed for use with single-source profiles, and the fact that many forensic samples are mixtures.
