Many plants show strong heteroblastic changes in the shape and size of organs as they transition from juvenile to reproductive age. Most attention has been focused on heteroblastic development in leaves, but we wanted to understand heteroblastic changes in reproductive organ size. We therefore studied the progression of reproductive development in the model plant Arabidopsis thaliana, and found strong reductions in the size of flowers, fruit, seed, and internodes during development.

Given the differences in geomorphology, climate, hydrology, and human activities in various regions, lake chemometrics may also vary. However, the spatial distribution of lake chemistry and the factors affecting such pattern are still unclear. Here, we collected data for carbon, nitrogen, and phosphorus from published literature and databases in 224 lakes and calculated the trophic status index to represent the nutrient classification state of lakes.

Male precopulatory oral stimulation of female genitals is rare for invertebrates. Here, we describe an intriguing oral sexual courtship in a cryptic desert beetle Faldermann.

Limitations in access to timely ASD diagnostic evaluations delay enrollment in interventions known to improve developmental outcomes. As such, developing and testing streamlined methods for ASD diagnosis is a public health and research priority.

Current CC initiatives are promising but lack adherence to emerging definitions/standards. A Lucile Packard Report provides guidelines for using a Shared Plan of Care (SPoC) as a CC approach; studied implementation is needed.

Using a Shared Plan of Care (SPoC) as a care coordination activity is recommended, but related research on outcomes in pediatric populations with complex medical conditions is scarce.
Objective: This study explores family outcomes associated with implementation of a care coordination/SPoC intervention with a population of children with neurodevelopmental disabilities and their families.
Rationale And Objectives: The present study investigated attentional modification of prepulse inhibition of startle among boys with and without attention-deficit hyperactivity disorder (ADHD). Two hypotheses were tested: (1) whether ADHD is associated with diminished prepulse inhibition during attended prestimuli, but not ignored prestimuli, and (2) whether methylphenidate selectively increases prepulse inhibition to attended prestimuli among boys with ADHD.
Methods: Participants were 17 boys with ADHD and 14 controls.
