To describe a new Baha surgical procedure (Modified Punch Technique) with a smaller punch hole, a minimal incision and the use of the hydroxyapatite-coated abutment (BIA400). Retrospective chart review. Patients were implanted between 2012 and 2013 at King Abdulaziz University Hospital (Kingdom of Saudi Arabia). Eligible for initial or replacement bone-anchored hearing system; includes six patients (four adults, two children). Baha surgery using the Punch Method is described. The mean surgical time was 12.33 min (range 6-30), without the single outlier, it was 8.8 min. Bleeding was significant but easily controlled in two patients only. Depending on the postauricular subcutaneous thickness, the sizes of abutment used were 6, 8, 10 or 12 mm. None of the patients experienced severe pain. The postoperative follow-up period was 7 months for one patient, 5 months for three patients, and 3 months for two patients. First report of combined Modified Punch Technique with the BIA400 abutment is minimally invasive, reduces surgical time and results in faster healing and reduced likelihood of postoperative numbness.

Target interception in virtual reality is better for natural versus unnatural trajectory shapes and orientations.

Neuroscience Program, University of Western Ontario, London, Ontario, Canada.
Human performance in perceptual and visuomotor tasks is enhanced when stimulus motion follows the laws of gravitational physics, including acceleration consistent with Earth's gravity, g. Here we used a manual interception task in virtual reality to investigate the effects of trajectory shape and orientation on interception timing and accuracy. Participants punched to intercept a ball moving along one of four trajectories that varied in shape (parabola or tent) and orientation (upright or inverted).

Repeated biomarker measurements provide greater sensitivity for detecting within-person change, which in clinical trials can allow for reductions in sample sizes required to detect treatment effects and shorten trial periods. We validated Dried Blood Spots (DBS) as a novel matrix for measuring blood biomarkers of AD, as collection is easily repeatable, less burdensome for participants, and more economical than phlebotomy, and shipment and storage are simplified.

The increasing demand for protein-rich, plant-based foods has driven the development of meat analogs that closely mimic the texture and mouthfeel of animal meat. While plant-based fibrils and electrospun silk fibroin fibers have been explored for texture enhancement and scaffolding in both meat analogs and cell-based meats, the use of wet-spun fibroin protein fibers as a food ingredient remains underexplored. This study investigates the potential of wet-spun recombinant fibroin fibers to enhance the textural properties of meat analogs.

This study evaluates two biostimulatory agents' effects on genes, expressed proteins, and respective pathways as potential aging biomarkers and treatment outcomes.
Methods: This 13-week, randomized, single-center, comparative study compared volume change and gene expression stimulated by poly-L-lactic acid (PLLA-SCATM) and calcium hydroxylapatite (CaHA-R) via punch biopsy in the nasolabial fold (NLF).
