Material and mechanical behavior of bracket fungi context as a mechanically versatile structural layer.

Bracket fungi sporocarps present promising environmentally friendly alternatives to harmful and wasteful structural applications with their high strength-to-weight ratio mechanical properties. Kingdom Fungi is estimated to have over three million species, yet only 4% of the species have been described by mycologists, and their mechanical behavior has been under-explored. This work aims to characterize the material behavior and mechanical properties of bracket fungi as a whole through micro-mechanical tensile testing combined with microstructural imaging and analysis of two representative species.

Likelihood of fitness improvements during a standardised physical fitness programme in US Army trainees of different fitness levels.

Unlabelled: IntroductionUS Army Initial Entry Training (IET) aims to develop general fitness and conditioning among large groups of trainees. Despite group mean improvement in physical fitness during IET, some trainees experience substantial gains and others experience no improvement or even declines in fitness. The purpose of this study was to examine the associations between trainee baseline fitness (Army Physical Fitness Test (APFT), the primary fitness assessment at the time of data collection) or estimated baseline body fat (%BF) and the change in fitness by the end of IET.

Increased AGE Cross-Linking Reduces the Mechanical Properties of Osteons.

Unlabelled: The osteon is the primary structural component of bone, contributing significantly to its unique toughness and strength. Despite extensive research on osteonal structure, the properties of osteons have not been fully investigated, particularly within the context of bone fragility diseases like type 2 diabetes mellitus (T2DM). This study aims to isolate osteons from bovine bone, simulate the effects of increased advanced glycation end-products (AGEs) in T2DM through ribosylation, and evaluate the mechanical properties of isolated osteons.

Use of an Automated Surgical Impactor Reduces Femoral Broaching Time in Direct Anterior Approach Total Hip Arthroplasty: Results From a Randomized, Multicenter Study.

Background: Impaction in total hip arthroplasty has typically been conducted using a mallet. A surgical automated impactor has been developed with the goal of reducing surgeon variability, fatigue, and injury. There is also potential to reduce the variability of each impaction step in which automated impaction is used, through reproducible and consistent application of force.
