Young and old subjects performed a mental rotation task with a within-subject instructional manipulation of speed/accuracy criteria. The three sets of instructions emphasized speed, accuracy, or both speed and accuracy equally. Both age groups changed reaction time (RT) in response to instructions, but there was no Age x Instruction interaction. Whereas young subjects showed decreases in accuracy with decreasing RT, older adults showed relatively stable levels of accuracy with decreasing RT, suggesting that young subjects were more willing to sacrifice accuracy for improvement in speed. Speed/accuracy operating characteristics for the two groups did not overlap, suggesting that age differences in response criteria cannot completely account for age differences in mental rotation performance.

Measuring lower extremity impact acceleration is a common strategy to identify runners with increased injury risk. However, existing axial peak tibial acceleration (PTA) thresholds for determining high-impact runners typically rely on small samples or fixed running speeds. This study aimed to describe the distribution of axial PTA among runners at their preferred running speed, determine an appropriate adjustment for investigating impact magnitude at different speeds, and compare biomechanics between runners classified by impact magnitude.

The human brain connectome is characterized by the duality of highly modular structure and efficient integration, supporting information processing. Newborns with congenital heart disease (CHD), prematurity, or spina bifida aperta (SBA) constitute a population at risk for altered brain development and developmental delay (DD). We hypothesize that, independent of etiology, alterations of connectomic organization reflect neural circuitry impairments in cognitive DD.

Objective: A gluten-free diet (GFD) is becoming increasingly popular, especially among young females, and including those without diagnosed celiac disease (CD). Whether a GFD is appropriate during pregnancy remains unclear. Our primary aim was to evaluate the association of a GFD and neonatal birthweight and incidence of large for gestational age (LGA) and small for gestational age (SGA).

Background: The Japanese giant silkworm (JGS) Caligula japonica is a significant defoliator pest in East Asia, causing severe economic losses in forest and fruit production. To establish a cost-effective biological control program against JGS, the age-stage, two-sex life table method was used to accurately assess the potential efficacy of two Mesocomys species (M. albitarsis and M.
