Summary: Fast, sensitive, and easy-to-use label-free electrochemical DNA biosensor method was developed for the detection of pork in processed meat samples. The method utilized gold electrodeposited screen-printed carbon electrodes and differential pulse voltammetry for probe-target DNA hybridization detection. The detection limit was 0.135 μg/mL, and the method showed selectivity against 5% pork DNA in a mixture of meat samples. This electrochemical biosensor method has the potential to be developed into a portable point-of-care detection method for pork or food adulterations.

Summary: The impacts of agriculture, especially livestock farming, on environmental degradation are a global concern. Advanced breeding and feeding strategies are necessary to meet the growing global demand for animal protein. Wild boar meat has the potential to be a substitute for pork, beef, and poultry, but its consumption rate is currently low. This review highlights the characteristics of wild boar meat and its potential for consumption, particularly in processed products.

Summary: In this work, gold nanoparticles@Ti3C2 MXenes nanocomposites were used to construct an electrochemical circulating tumor DNA biosensor via toehold-mediated DNA strand displacement reaction. The biosensor has a linear detection range of 10 fM-10 nM and a detection limit of 0.38 fM, and can efficiently distinguish single base mismatched DNA sequences. The biosensor has been successfully applied for the sensitive detection of KRAS gene G12D, showing great potential for clinical analysis.

Summary: Electrochemical immunosensors offer rapid analyte quantification with high sensitivity and selectivity, but user-friendliness can often be a challenge. Using silver nanoparticles instead of gold nanoparticles in POC sensors not only improves sensitivity, but also simplifies assay protocols to meet POC requirements, achieving lower limits of detection in a 2-minute automatic measurement.

Summary: Mitochondrial DNA (mtDNA) deficiency is associated with poor oocyte quality and fertilisation failure. Supplementing mtDNA deficient oocytes with extra copies of mtDNA improves fertilisation rates and embryo development. The molecular mechanisms underlying oocyte developmental incompetence and the effects of mtDNA supplementation on embryo development are still unclear. This study investigates the association between the developmental competence of Sus scrofa oocytes, assessed with Brilliant Cresyl Blue, and transcriptome profiles. The effects of mtDNA supplementation on the developmental transition from oocyte to blastocyst are also analyzed.

Summary: A biosensor using AuNP-modified AuE and CPs was developed for the detection of miR-100 in GC patients' sera. The biosensor showed high specificity and sensitivity in distinguishing miR-100 variants, with a detection range from 100 aM to 10 pM and a LOD of 100 aM. The cutoff for gastric cancer detection was determined to be 5 fM based on testing 100 human sera samples.

Summary: Oocytes can be supplemented with extra copies of mtDNA to improve developmental outcome, with minor differences observed in growth and health of pigs derived from autologous and heterologous mtDNA. However, it is unclear if changes in gene expression during preimplantation development persist and affect gene expression in adult tissues, and if the source of mtDNA influences gene expression patterns. Transcriptome analyses revealed common effects on immune response and glyoxylate metabolism genes in brain, heart, and liver tissues by mtDNA supplementation, with a link to oxidative phosphorylation genes when using third-party mtDNA.
