Aim: Insertion of dental implants causes bone deformation and induces residual bone compression stress, which can lead to implant failure if the bone loss threshold is exceeded. The current literature about bone stress is restricted to computer simulations and implant primary stability measurements after installation. This work measures the torque and deformation during implant insertion testing.

The aim of this study was to evaluate the influence of implant macrodesign and surface hydrophilicity on osteoclast (OC) differentiation, activation, and survival in vitro. Titanium disks were produced with a sandblasted, dual acid-etched surface, with or without additional chemical modification for increasing hydrophilicity (SAE-HD and SAE, respectively) and different macrodesign comprising trapezoidal (HLX) or triangular threads (TMX). This study evaluated 7 groups in total, 4 of which were experimental: HLX/SAE-HD, HLX-SAE, TMX/SAE-HD, and TMX/SAE; and 3 control groups comprising OC differentiated on polystyrene plates (CCPC): a positive CCPC (+), a negative CCPC (-), and a lipopolysaccharide-stimulated assay positive control group, CCPC-LPS.

The auditory cortex is the source of descending connections providing contextual feedback for auditory signal processing at almost all levels of the lemniscal auditory pathway. Such feedback is essential for cognitive processing. It is likely that corticofugal pathways are degraded with aging, becoming important players in age-related hearing loss and, by extension, in cognitive decline.

Background: Previous studies report that intraoperative hypotension worsens outcomes after aneurysmal subarachnoid hemorrhage (aSAH). However, the hypotensive harm threshold for major adverse cardiovascular events (MACE) remains unclear.
Methods: The authors included aSAH patients who had general anesthesia for aneurysmal clipping/coiling.

Digital mucous cysts (DMCs), also known as myxoid cysts, periungual ganglion cysts, and myxomatous cutaneous cysts, commonly occurr at the distal interphalangeal joint (DIPJ) of the fingers and toes. Due to the dense and inflexible skin at the dorsal fingertip, wound dehiscence and necrosis may sometimes be caused by tension sutures. The keystone flap (KF), designed as a curvilinear-shaped trapezoidal keystone with two V-Y advancements at the exterior peripheral corners, has been gaining popularity as a local flap that can close defects with a lower tension.
