Feeding Practices Used by Australian Parents of Young Children Living With Food Insecurity and Household Chaos.

Responsive feeding practices are crucial for developing healthy eating behaviours in children. However, chaotic households and financial stress may disrupt these practices. This cross-sectional study aimed to characterise feeding practices among Australian parents experiencing financial hardship.

The 141-year period for Dr. Beal's seed viability experiment: A hybrid surprise.

Premise: In 1879, Dr. William Beal buried 20 glass bottles filled with seeds and sand at a single site at Michigan State University. The goal of the experiment was to understand seed longevity in the soil, a topic of general importance in ecology, restoration, conservation, and agriculture, by periodically assaying germinability of these seeds over 100 years.

The Trauma Symptom Checklist for Young Children: A Psychometric Review.

Unlabelled: The Trauma Symptom Checklist for Young Children (TSCYC) is a 90-item caregiver-report measure of childhood traumatic stress and abuse-related experiences in children, ages three to twelve years old.

Purpose: The objective of this review is to examine the current empirical evidence ( = 22) regarding the psychometric properties of the TSCYC.

Method: A variety of study designs were reviewed for psychometric evidence supporting the reliability and validity of the TSCYC.

Developmental Genetics of Corolla Tube Formation: Role of the tasiRNA- Pathway and a Conceptual Model.

Over 80,000 angiosperm species produce flowers with petals fused into a corolla tube. The corolla tube contributes to the tremendous diversity of flower morphology and plays a critical role in plant reproduction, yet it remains one of the least understood plant structures from a developmental genetics perspective. Through mutant analyses and transgenic experiments, we show that the tasiRNA- pathway is required for corolla tube formation in the monkeyflower species Loss-of-function mutations in the orthologs of and cause a dramatic decrease in abundance of -derived small RNAs and a moderate upregulation of () and , which lead to inhibition of lateral expansion of the bases of petal primordia and complete arrest of the upward growth of the interprimordial regions, resulting in unfused corollas.

Two MYB Proteins in a Self-Organizing Activator-Inhibitor System Produce Spotted Pigmentation Patterns.

Many organisms exhibit visually striking spotted or striped pigmentation patterns. Developmental models predict that such spatial patterns can form when a local autocatalytic feedback loop and a long-range inhibitory feedback loop interact. At its simplest, this self-organizing network only requires one self-activating activator that also activates a repressor, which inhibits the activator and diffuses to neighboring cells.

A Tetratricopeptide Repeat Protein Regulates Carotenoid Biosynthesis and Chromoplast Development in Monkeyflowers ().

Little is known about the factors regulating carotenoid biosynthesis in flowers. Here, we characterized the () locus from two monkeyflower () species, the bumblebee-pollinated species and the hummingbird-pollinated species We show that loss-of-function mutations of cause drastic down-regulation of the entire carotenoid biosynthetic pathway. The causal gene underlying encodes a tetratricopeptide repeat protein that is closely related to the Arabidopsis () REDUCED CHLOROPLAST COVERAGE proteins.

Transcriptional Regulation of Carotenoid Biosynthesis in Plants: So Many Regulators, So Little Consensus.

In plants, the carotenoid biosynthesis pathway (CBP) is essential for the production of photosynthetic and protective pigments, plant hormones, and visual/olfactory attractants for animal pollinators and seed dispersers. The regulation of carotenoid biosynthesis at the transcriptional level is vitally important for all of these functions and has been the subject of intensive research. Many putative transcriptional regulators, both direct and indirect, have been identified through conventional mutant analysis, transcriptome profiling, yeast one-hybrid screening, and candidate gene approaches.

The Influence of Youth Gender and Complex Trauma on the Relation Between Treatment Conditions and Outcomes in Therapeutic Residential Care.

Complex trauma (CT) is the experience, or witness, of prolonged abuse or neglect that negatively affects children's emotional and psychological health. Youth in residential care experience higher incidences of complex trauma than youth in community-based care, with notable gender differences and presentation of psychological symptoms. This study examined the effects of trauma-informed residential care and the relation between CT and gender.

Colorectal Cancer Screening: Role of Family Physicians.

The purpose of this study was to look at the differences in colorectal cancer screening awareness between two rural communities in Texas. In Clifton, patients have access to colonoscopies in their local hospital, while in Haskell, patients have to travel to a tertiary center. A 24-question survey pertaining to colon cancer from the Behavior Risk Factor Surveillance System (BRFSS) was given to patients at primary care clinics in Clifton and Haskell.

Is the Preschool PATHS Curriculum Effective? A Review.

The preschool PATHS curriculum was designed as a universal preschool classroom curriculum to improve children's social-emotional learning and reduce problem behaviors. : This review examined the published outcome studies ( = 5) of the preschool PATHS curriculum examining social-emotional and problem behavior outcome measures. : One randomized control trial, two quasi-experimental designs and two pre-experimental designs met the inclusion criteria and were reviewed.

Competition between anthocyanin and flavonol biosynthesis produces spatial pattern variation of floral pigments between Mimulus species.

Flower color patterns have long served as a model for developmental genetics because pigment phenotypes are visually striking, yet generally not required for plant viability, facilitating the genetic analysis of color and pattern mutants. The evolution of novel flower colors and patterns has played a key role in the adaptive radiation of flowering plants via their specialized interactions with different pollinator guilds (e.g.

An R2R3-MYB transcription factor regulates carotenoid pigmentation in Mimulus lewisii flowers.

Carotenoids are yellow, orange, and red pigments that contribute to the beautiful colors and nutritive value of many flowers and fruits. The structural genes in the highly conserved carotenoid biosynthetic pathway have been well characterized in multiple plant systems, but little is known about the transcription factors that control the expression of these structural genes. By analyzing a chemically induced mutant of Mimulus lewisii through bulk segregant analysis and transgenic experiments, we have identified an R2R3-MYB, Reduced Carotenoid Pigmentation 1 (RCP1), as the first transcription factor that positively regulates carotenoid biosynthesis during flower development.
