AI Article Synopsis
- The study tested how well various fingerprint enhancement methods and lifting techniques work with DNA profiling, focusing on both modern and historical methods.
- A total of 180 fingerprints were deposited, enhanced, and lifted, showing that DNA profiles could be successfully obtained without major differences between techniques.
- The findings indicate that using different combinations of powders and lifting techniques is compatible with DNA extraction, enhancing the usefulness of fingerprints as evidence in forensics.
Article Abstract
This study evaluated the compatibility of the most common enhancement methods and lifting techniques with DNA profiling. Emphasis is placed on modern lifting techniques (i.e., gelatin lifters and Isomark™) and historical fingerprint lifts for which limited research has been previously conducted. A total of 180 fingerprints were deposited on a glass surface, enhanced, lifted, and processed for DNA typing. DNA could be extracted and profiled for all the powders and lifts tested and from both groomed fingerprints and natural prints with no significant difference in the percentage of profile recovered. DNA profiles could also be obtained from historical fingerprint lifts (79.2% of 72 lifts) with one or more alleles detected. These results demonstrate the compatibility between different powder/lift combinations and DNA profiling therefore augmenting the evidential value of fingerprints in forensic casework.

Epithelial cancers are typically heterogeneous with primary prostate cancer being a typical example of histological and genomic variation. Prior studies of primary prostate cancer tumour genetics revealed extensive inter and intra-patient genomic tumour heterogeneity. Recent advances in machine learning have enabled the inference of ground-truth genomic single-nucleotide and copy number variant status from transcript data.

The synthesis and characterization of benzo[d]thiazol-2-amine derivatives, which were prepared by reacting benzothiazole with para-aminobenzophenone in ethanol, supplemented with glacial acetic acid. Subsequently, compound (2) was synthesized from compound (1) using NaNO, HPO, and HNO in a water-based solvent, resulting in 2-hydroxy-1-naphthaldehyde. Another derivative, compound (3), was synthesized by reacting compound (1) with vanillin under similar conditions.

Background: Huntington's disease (HD) is an autosomal dominant condition causing severe neurodegeneration in the striatum and the entorhinal cortex (EC). An epigenome wide association study of DNA methylation in HD by our group, identified potential hypomethylation at the PTGDS gene in the striatum. We aimed to validate this result through pyrosequencing, examining the locus in fine detail, and to assess the signal specificity by profiling multiple neurodegenerative diseases.

Background: Psychosis (broadly delusions and hallucinations) has a cumulative disease prevalence of around 40% in Alzheimer's disease (AD). The epigenomic, genomic, and neuropathological data provide powerful evidence that AD+P has a distinct neurobiological profile. Here, we used the weighted gene co-expression network analysis (WGCNA) method to investigate DNA methylation associated with AD+P in the dorsolateral prefrontal cortex of 153 post-mortem brain samples.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disease that inflicts the elderly worldwide. Recent studies revealed the association of abnormal methylomic alterations in AD. However, a systematic and comprehensive study is needed to investigate the effects of methylomic changes on the molecular networks underpinning AD, in particular, in brain regions most vulnerable to AD neuropathology.
