Engineering thermostable fluorescent DNA aptamer for the isothermal amplification of nucleic acids.

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.

Preparation and Gas-Sensitive Properties of SnO@BiO Core-Shell Heterojunction Structure.

The SnO@BiO core-shell heterojunction structure was designed and synthesized via a hydrothermal method, and the structure and morphology of the synthesized samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). Based on the conclusions from XRD and SEM, it can be observed that as the hydrothermal temperature increases, the content of BiO coated on the surface of SnO spheres gradually increases, and the diameter of BiO nanoparticles also increases. At a hydrothermal temperature of 160 °C, the SnO spheres are fully coated with BiO nanoparticles.

Enhancing predictive accuracy for urinary tract infections post-pediatric pyeloplasty with explainable AI: an ensemble TabNet approach.

Ureteropelvic junction obstruction (UPJO) is a common pediatric condition often treated with pyeloplasty. Despite the surgical intervention, postoperative urinary tract infections (UTIs) occur in over 30% of cases within six months, adversely affecting recovery and increasing both clinical and economic burdens. Current prediction methods for postoperative UTIs rely on empirical judgment and limited clinical parameters, underscoring the need for a robust, multifactorial predictive model.

Expanding the Landscape of Aging via Orbitrap Astral Mass Spectrometry and Tandem Mass Tag (TMT) Integration.

Aging results in a progressive decline in physiological function due to the deterioration of essential biological processes, such as transcription and RNA splicing, ultimately increasing mortality risk. Although proteomics is emerging as a powerful tool for elucidating the molecular mechanisms of aging, existing studies are constrained by limited proteome coverage and only observe a narrow range of lifespan. To overcome these limitations, we integrated the Orbitrap Astral Mass Spectrometer with the multiplex tandem mass tag (TMT) technology to profile the proteomes of three brain tissues (cortex, hippocampus, striatum) and kidney in the C57BL/6JN mouse model, achieving quantification of 8,954 to 9,376 proteins per tissue (cumulatively 12,749 across all tissues).

Multienzyme cascade for synthesis of hydroxytyrosol via engineered Escherichia coli.
