The American Academy of Pediatrics (AAP) defines standard guidelines for infant positioning and sleep environment to reduce the rate of sudden infant death syndrome (SIDS), but recent data on nurses' knowledge and adherence to these guidelines in hospital settings are limited. An observational, quantitative, and descriptive study was conducted on well-baby postpartum nurseries at two urban Wash...

This study investigated the effect of the palatal crib appliance used in the correction of open bite malocclusions secondary to fingersucking. Twelve experimental and 12 control subjects were studied for an average of 3.9 months. The sample consisted of patients who were both growing and not growing. Study models taken before and after the study period were analyzed for changes in the following...

The p21-activated kinase (PAK) group of serine/threonine kinases are downstream effectors of RHO GTPases and play important roles in regulation of the actin cytoskeleton, cell growth, survival, polarity, and development. Here we probe the interaction of the type II PAK, PAK4, with RHO GTPases. Using solution scattering we find that the full-length PAK4 heterodimer with CDC42 adopts primarily a ...

This paper summarizes our theoretical understanding of supernova events in a “back of the envelope” way. It is intended to aid in the recognition and understanding of those events which are not “standard”, and which may provide the most insight.

Physical behaviors (e.g., sleep, sedentary behavior, and physical activity) often occur in sustained bouts that are punctuated with brief interruptions. To detect classify these interrupted bouts, researchers commonly use wearable devices specialized algorithms. Most algorithms examine the data chronological order, initiating terminating whenever specific criteria met. Consequently, may encapsu...

Background—There is controversy over whether improved survival of preterm infants has resulted in a higher incidence of severe (grade 3 or greater) retinopathy of prematurity (ROP). Aim—To compare survival rates and rates of > stage 3 ROP—that is, with a high risk of sequelae—in preterm infants in five English cities where, anecdotally, the incidence of ROP is reported to show considerable vari...
