Reaping a good light harvest: Femtosecond spectroscopy uncovered a novel pathway of singlet–singlet excitation‐energy transfer (EET) from bacteriochlorophyll (Bchl) in a purple bacterium to the carotenoid spirilloxanthin (Spx) upon the excitation of Bchl into the Qx band (see picture). This pathway was also clearly identified in steady‐state fluorescence excitation spectra, but only in the presence of Spx. IC=internal conversion.

Objective Our objective was to evaluate the efficacy of the Sitting Together and Reaching to Play (START-Play) intervention in young infants with neuromotor disorders. Method This randomized controlled trial compared usual care early intervention (UC-EI) with START-Play plus UC-EI. Analyses included 112 infants with motor delay (55 UC-EI, 57 START-Play) recruited at 7 to 16 months of age across 5 sites. START-Play included twice-weekly home visits with the infant and caregiver for 12 weeks provided by physical therapists trained in the START-Play intervention; UC-EI was not disrupted. Outcome measures were the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley); the Gross Motor Function Measure; reaching frequency; and the Assessment of Problem Solving in Play (APSP). Comparisons for the full group as well as separate comparisons for infants with mild motor delay and infants with significant motor delay were done. Piecewise linear mixed modeling estimated short- and long-term effects. Results For infants with significant motor delay, positive effects of START-Play were observed at 3 months for Bayley cognition, Bayley fine motor, and APSP and at 12 months for Bayley fine motor and reaching frequency outcomes. For infants with mild motor delay, positive effects of START-Play for the Bayley receptive communication outcome were found. For the UC-EI group, the only difference between groups was a positive effect for the APSP outcome, observed at 3 months. Conclusions START-Play may advance reaching, problem-solving, cognitive, and fine motor skills for young infants with significant motor delay over UC-EI in the short term. START-Play in addition to UC-EI may not improve motor/cognitive outcomes for infants with milder motor delays over and above usual care. Impact Concepts of embodied cognition, applied to early intervention in the START-Play intervention, may serve to advance cognition and motor skills in young infants with significant motor delays over usual care early intervention. Lay Summary If you have a young infant with significant delays in motor skills, your physical therapist can work with you to develop play opportunities to enhance your child’s problem-solving, such as that used in the START-Play intervention, in addition to usual care in order to help your child advance cognitive and motor skills.

Service providers are encouraged to focus on child and family needs for general information. Research is needed to better understand parent perspectives of service provider participatory behaviors which are important for engaging families in intervention processes.

The trunk neural crest of vertebrate embryos gives rise to dorsal root ganglion (DRG) sensory neurons and autonomic sympathetic neurons, among other derivatives. We have examined the development of DRG and sympathetic neurons during development in the zebrafish. We found that sensory neurons differentiate rapidly and that their overt neuronal differentiation significantly precedes that of sympathetic neurons in the trunk. Sympathetic neurons in different regions differentiate at different times. The most rostral population, which we call the cervical ganglion, differentiates several days before trunk sympathetic neurons. After undergoing overt neuronal differentiation, sympathetic neurons subsequently express the adrenergic differentiation markers dopamine beta-hydroxylase and tyrosine hydroxylase. A second population of adrenergic nonneuronal cells initially localized with cervical sympathetic neurons appears to represent adrenal chromaffin cells. In more mature fish, these cells were present in clusters within the kidneys. Individual DRG and sympathetic ganglia initially contain few neurons. However, the number of neurons in DRG and sympathetic ganglia increases continuously at least up to 4 weeks of age. Analysis of phosphohistone H3 expression and bromodeoxyuridine incorporation studies suggests that the increases in DRG and sympathetic ganglion neuronal cell number are due wholly or in part to the division of neuronal cells within the ganglia.

In vivo antitumor efficacy combined with the specificity of CMP5 underscores the importance of developing it for translation.

The model may have utility for optimizing collaboration between families and professionals to foster family empowerment and optimize child and family outcomes. Implications for Rehabilitation Family--professional collaboration is essential to optimize outcomes of children with disabilities and families. The model of collaborative service delivery is based on three key principles: family identified needs, shared responsibility, and family empowerment. The model of collaborative service delivery is implemented using a four step process: (1) mutually agreed-upon goals, (2) shared-planning, (3) shared implementation, and (4) shared-evaluation. The unique feature of the model is the integration of specific strategies and procedures for professionals to foster collaborative processes between families and professionals.

Our data demonstrate that B. lactis inhibits NF-kappaB and NF-kappaB-regulated genes in IEC and prevents acute colitis and CAC in mice. These results suggest that B. lactis could be a potential preventive agent for CAC as well as a therapeutic agent for inflammatory bowel disease.

Participation in home, school, and community activities is a primary outcome of early intervention services for children with disabilities and their families. The objectives of this study were to (a) describe participation of preschool-age children with cerebral palsy (CP); (b) determine effects of sex, age, and gross motor function on intensity of participation; and (c) identify child, family, and service determinants of intensity of participation. A convenience sample of 85 preschool-age children with CP and their parents participated. Parents completed self-report measures on children's participation, adaptive behavior, physical function, family functioning, and services. Children's Gross Motor Function Classification System levels (Palisano, Rosenbaum, Bartlett, & Livingston, 2008) were determined by assessors. A multiple linear regression analysis was conducted to determine the variance in intensity of participation explained by the determinants. Children with limited self-mobility had a lower intensity of participation than children with independent upright mobility. Adaptive behavior, transfers and basic mobility function, and upper extremity and physical function explained 46% of the variance of intensity of participation.
