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.

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.

Nitrous oxide-induced neurological disorders: an increasing public health concern.

Background: Neurological presentations resulting from nitrous oxide (N O) abuse are increasing in Australia and worldwide. Despite known neuropsychiatric sequelae, N O canisters remain readily available and its use unregulated.

Aims: To examine the demographics, clinical and electrophysiological findings of patients presenting with neurological complications of N O abuse, and thus inform clinicians and public health decision-makers of the significant public health concerns of this increasing practice.

Can an automated sleep detection algorithm for waist-worn accelerometry replace sleep logs?

The purpose of this study was to test whether estimates of bedtime, wake time, and sleep period time (SPT) were comparable between an automated algorithm (ALG) applied to waist-worn accelerometry data and a sleep log (LOG) in an adult sample. A total of 104 participants were asked to log evening bedtime and morning wake time and wear an ActiGraph wGT3X-BT accelerometer at their waist for 24 h/day for 7 consecutive days. Mean difference and mean absolute difference (MAD) were computed.

Acute effect of high-intensity cycling exercise on carotid artery hemodynamic pulsatility.

Purpose: Investigate the effects of acute high-intensity exercise on common carotid artery (CCA) dimensions, stiffness, and wave intensity.

Methods: Fifty-five healthy men and women (22 ± 5 year; 24.5 ± 2.

Physical activity offsets the negative effects of a high-fructose diet.

Objective: This study aimed to determine the interaction between a high-fructose diet and PA levels on postprandial lipidemia and inflammation in normal-weight, recreationally active individuals.

Methods: Twenty-two men and women (age, 21.2 ± 0.

The effect of intra-uterine growth restriction on blood lipids and response to exercise training.

Objectives: To determine if a small body size at birth is associated with an unfavorable metabolic profile and a reduced response to exercise training in young adults.

Methods: Thirty-six college students, all singletons born to term, participated. Subjects were defined as either high ponderal index (HIGHPI) or low ponderal index (LOWPI).

Activity patterns and perceptions about active transport to school.

Objectives: To document physical activity patterns and perceptions about active transport to school.

Methods: Children's activity was measured. Children and parents were surveyed about active transport to school.
