Association between frailty, as measured by the FRAIL scale, and 1-year mortality in older patients undergoing hip fracture surgery.

Background: The FRAIL scale is a concise and user-friendly tool for frailty assessment. However, its effectiveness in predicting 1-year mortality among older patients undergoing hip fracture surgery remains unclear. This study explored the relationship between preoperative frailty, as measured by the FRAIL scale, and 1-year mortality after surgery in this population.

Adenine base editor corrected ADPKD point mutations in hiPSCs and kidney organoids.

Autosomal dominant polycystic kidney disease (ADPKD) is a dominant genetic disorder caused primarily by mutations in the PKD1 gene, resulting in the formation of numerous cysts and eventually kidney failure. However, there are currently no gene therapy studies aimed at correcting PKD1 gene mutations. In this study, we identified two mutation sites associated with ADPKD, c.

RNA structure: implications in viral infections and neurodegenerative diseases.

RNA is an intermediary between DNA and protein, a catalyzer of biochemical reactions, and a regulator of genes and transcripts. RNA structures are essential for complicated functions. Recent years have witnessed rapid advancements in RNA secondary structure probing techniques.

Cathepsin B Activatable Fluorescent Probe for Antitumor Efficiency Feedback: Attempt To Detect Certain Apoptotic Cells.

As many treatments kill tumor cells by inducing apoptosis, fluorescent probes that can detect apoptosis are crucial for effective feedback regarding tumor therapy outcomes (in particular, activatable probes for better imaging). Cathepsins are enzymes that are released from lysosomes into the cytoplasm during lysosomal membrane permeabilization-induced apoptosis of many tumor cells, making them potential biomarkers of apoptotic cells. Despite their potential, to the best of our knowledge, no cathepsin-activatable fluorescent probes have been reported for this purpose.

Precise morphology control of all-organic core-shell droplets for synthesis of microencapsulated phase change materials through AC electric fields.

Hypothesis: Complex emulsions usually consist of aqueous phases, like oil-in-water-in-oil (o/w/o) and water-in-oil-in-water (w/o/w), serving foundational roles in colloid science. Oil-in-oil-oil (o/o/o) emulsions offer new avenues for non-aqueous reagents but face challenges in balancing the forces between multiple organic phases.

Experiments: In this work, we generate o/o/o emulsions by integrating an AC electric field with a double cross-junction microchannel.
