The Tertiary Survey as a Quality Improvement Initiative in Pediatric Trauma Care.

Background: Patients are at risk of missed or delayed injuries in the setting of multisystem trauma, which may be identified with a tertiary trauma survey (TTS). There is limited literature to support the utilization of a TTS in pediatric trauma population. We aim to assess the impact of the TTS as a quality and performance improvement tool in identifying missed or delayed injuries and improving the quality of care among pediatric trauma population.

Hemodynamic Parameters and Early Intimal Thickening in Branching Blood Vessels.

Intimal thickening due to atherosclerotic lesions or intimal hyperplasia in medium to large blood vessels is a major contributor to heart disease, the leading cause of death in the Western World. Balloon angioplasty with stenting, bypass surgery, and endarterectomy (with or without patch reconstruction) are some of the techniques currently applied to occluded blood vessels. On the basis of the preponderance of clinical evidence that disturbed flow patterns play a key role in the onset and progression of atherosclerosis and intimal hyperplasia, it is of interest to analyze suitable hemodynamic wall parameters that indicate susceptible sites of intimal thickening and/or favorable conditions for thrombi formation.

Review of the systematic status of Sceloporus arenicolus Degenhardt and Jones, 1972 with an estimate of divergence time.

The sagebrush lizards (Sceloporus graciosus group) consist of four taxa (S. graciosus graciosus, S. graciosus gracilis, S.

High-resolution fMRI reveals match enhancement and attentional modulation in the human medial temporal lobe.

A primary function of the medial temporal lobe (MTL) is to signal prior encounter with behaviorally relevant stimuli. MTL match enhancement--increased activation when viewing previously encountered stimuli--has been observed for goal-relevant stimuli in nonhuman primates during delayed-match-to-sample tasks and in humans during more complex relational memory tasks. Match enhancement may alternatively reflect (a) an attentional response to familiar relative to novel stimuli or (b) the retrieval of contextual details surrounding the past encounter with familiar stimuli.

Applying Undertaker to quality assessment.

Our group tested three quality assessment functions in CASP8: a function which used only distance constraints derived from alignments (SAM-T08-MQAO), a function which added other single-model terms to the distance constraints (SAM-T08-MQAU), and a function which used both single-model and consensus terms (SAM-T08-MQAC). We analyzed the functions both for ranking models for a single target and for producing an accurate estimate of GDT_TS. Our functions were optimized for the ranking problem, so are perhaps more appropriate for metaserver applications than for providing trustworthiness estimates for single models.

Candidate Agtr2 influenced genes and pathways identified by expression profiling in the developing brain of Agtr2(-/y) mice.

Intellectual disability (ID) is a common developmental disability observed in 1 to 3% of the human population. A possible role for the Angiotensin II type 2 receptor (AGTR2) in brain function, affecting learning, memory, and behavior, has been suggested in humans and rodents. Mice lacking the Agtr2 gene (Agtr2(-/y)) showed significant impairment in their spatial memory and exhibited abnormal dendritic spine morphology.

The c.940G variant of the Microcephalin (MCPH1) gene is not associated with microcephaly or mental retardation.

It was reported that positive selection has acted upon a gene involved in autosomal recessive primary microcephaly, Microcephalin (MCPH1/BRIT1), located at chromosome 8p23. We tested if the reported diagnostic single nucleotide polymorphism (SNP) (G37995C or c.940G > C) of a derived haplogroup of the MCPH1 gene had significantly different frequencies in mental retardation (MR) patients and in MR patients with microcephaly as compared to MR patients without microcephaly and controls in African-American and Caucasian populations in South Carolina, US.
