Targeting of zyxin to sites of actin membrane interaction and to the nucleus

Journal ArticleThe localization of proteins to particular intracellular compartments often regulates their functions. Zyxin is a LIM protein found prominently at sites of cell adhesion, faintly in leading lamellipodia, and transiently in cell nuclei. Here we have performed a domain analysis to identify regions in zyxin that are responsible for targeting it to different subcellular locations

Targeted disruption of the murine zyxin gene

Journal ArticleZyxin is an evolutionarily conserved protein that is concentrated at sites of cell adhesion, where it associates with members of the Enabled (Ena)/vasodilator-stimulated phosphoprotein (VASP) family of cytoskeletal regulators and is postulated to play a role in cytoskeletal dynamics and signaling

Cultural and Contextual Adaptation of a Childhood Obesity Preventive Intervention Program

This article describes the adaptation of a parent-focused evidence-based childhood obesity intervention program for implementation by county-based Extension educators in coordination with school district personnel in rural Pennsylvania. The Lifestyle Positive Parenting Program was designed and evaluated in Australia in clinical settings. Several minor and more serious adaptations, such as featured recipes and content of follow-up telephone calls, were made so that the program would be more appropriate for and appealing to target families. Conceptual issues regarding the adaptation of evidence-based programs are reviewed

Parent-Focused Childhood Obesity Intervention Improves Family Functioning and Children\u27s Well-Being

An Extension-implemented parent-focused childhood obesity intervention designed to improve family functioning around healthful eating and exercise was evaluated. Thirty-six parents and their children, aged 5–13, were randomized to a 12-week intervention condition or control condition. Intervention parents, compared to control group parents, felt more confident in promoting children\u27s healthful eating and exercise, worried less about their children\u27s weight, and engaged in fewer counterproductive parenting behaviors. The children of these parents, as compared to children of control group parents, lost weight and displayed better social-emotional functioning. These results highlight Extension\u27s important role in disseminating evidence-based childhood obesity interventions

An evaporation-based model of thermal neutron induced ternary fission of plutonium

Ternary fission probabilities for thermal neutron induced fission of plutonium are analyzed within the framework of an evaporation-based model where the complexity of time-varying potentials, associated with the neck collapse, are included in a simplistic fashion. If the nuclear temperature at scission and the fission-neck-collapse time are assumed to be ~1.2 MeV and ~10^-22 s, respectively, then calculated relative probabilities of ternary-fission light-charged-particle emission follow the trends seen in the experimental data. The ability of this model to reproduce ternary fission probabilities spanning seven orders of magnitude for a wide range of light-particle charges and masses implies that ternary fission is caused by the coupling of an evaporation-like process with the rapid re-arrangement of the nuclear fluid following scission.Comment: 25 pages, 12 figures, accepted for publication in IJMP

Improving Maternal Mental Health Following Preterm Birth Using an Expressive Writing Intervention: A Randomized Controlled Trial.

Evaluations of evidence-based, easily accessible, psychological interventions to improve maternal mental health following very preterm birth are scarce. This study investigated the efficacy and acceptability of the expressive writing paradigm for mothers of very preterm infants. The level of maternal posttraumatic stress and depressive symptoms was the primary outcome. Participants were 67 mothers of very preterm babies who were randomly allocated into the intervention (expressive writing; n = 33) or control group (treatment-as-usual; n = 32) when their infant was aged 3 months (corrected age, CA). Measurements were taken at 3 months (pre-intervention), 4 months (post-intervention), and 6 months CA (follow-up). Results showed reduced maternal posttraumatic stress (d = 0.42), depressive symptoms (d = 0.67), and an improved mental health status (d = 1.20) in the intervention group, which were maintained at follow-up. Expressive writing is a brief, cost-effective, and acceptable therapeutic approach that could be offered as part of the NICU care

Final Report: Buffalo National River Ecosystems

The objective of this study was to sample the Buffalo River on a seasonal basis for a year, in order to determine whether any potential water quality problems existed
