A universal DNA microarray for rapid fish species authentication.

DNA microarrays are now used in fields such as gene expression analysis, pathogen/virus detection and identification of biomarkers. Although they have been used in the food sector for species identification, they detect a limited number of species and are thus less suited for fishery products due to the large variety of traded species. Here, the aim of this proof-of-principle study was to design a universal DNA microarray that should be able to distinguish all fish species by comparing hybridization signal patterns from samples with patterns obtained from reference specimens.

Point-of-care ultrasonography-An essential skill for medical graduates?

The recent proliferation of point-of-care ultrasonography (POCUS) in the clinical practice of many medical specialties has exposed persistent barriers to education, training and standardisation. Specialist training curriculums are already overwhelming, having grossly insufficient time available for the specialist trainees and for the small number of available trainers alike to incorporate POCUS into postgraduate education. The logical solution to overcome these barriers could be to incorporate basic POCUS education and training into the undergraduate university curriculums, introducing longitudinal integration with other relevant medical sciences.

Differentiable partition function calculation for RNA.

Ribonucleic acid (RNA) is an essential molecule in a wide range of biological functions. In 1990, McCaskill introduced a dynamic programming algorithm for computing the partition function of an RNA sequence. McCaskill's algorithm is widely used today for understanding the thermodynamic properties of RNA.

Novel student roles in health care delivery: An example emerging from the COVID-19 health care crisis in 2021.

In 2021, the rapid rise in COVID-19 infections put overwhelming demand on health care services. It was recognised that patients could be managed in the community if an appropriate monitoring service existed. Medical students were recruited for roles that combined technology, teamwork and clinical skills.

Conserved intramolecular networks in GDAP1 are closely connected to CMT-linked mutations and protein stability.

Charcot-Marie-Tooth disease (CMT) is the most common inherited peripheral polyneuropathy in humans, and its subtypes are linked to mutations in dozens of different genes, including the gene coding for ganglioside-induced differentiation-associated protein 1 (GDAP1). The main GDAP1-linked CMT subtypes are the demyelinating CMT4A and the axonal CMT2K. Over a hundred different missense CMT mutations in the GDAP1 gene have been reported.
