conclusions closed reduction and hybrid external fixation can be used as a definitive treatment for severe comminuted fractures of the distal femur and proximal tibia, when the concomitant contusion of the skin and soft tissue damage prohibits safe open reduction and internal fixation. patients and methods in a prospective study, 44 patients with comminuted fractures of the distal femur or prox...

PURPOSE: To evaluate whether peripherally inserted central catheters (PICCs) with a proximal valve have any advantage compared to those with a distal valve in regard to the incidence of occlusion, infection, or malfunction. MATERIALS AND METHODS: One hundred patients (mean age, 46 y) were randomized to receive either a distal-valved Bard Groshong catheter (n = 48) or a proximal-valved Catheter ...

Interaction between angiotensin II, which binds a G-protein-coupled receptor, and insulin, a ligand for receptor tyrosine kinase, was examined in renal proximal tubular epithelial cells. Augmented protein translation by insulin involves activation of eukaryotic initiation factor 4E (eIF4E) which follows the release of the factor from a heterodimeric complex by phosphorylation of its binding pro...

We discuss agent-based models (ABM) as research tools for developmental and social psychology. “Agents” are computer-based entities, e.g., “people.” The modeler assigns the agents real-world roles and rules, conducts simulation experiments in which the agents follow their rules, and observes real-time data. Agent-based models have some properties that can be very useful to psychology. Agent-bas...

Classroom assessment is for the improvement of a learner’s diverse ability, teachers teaching strategies as well entire educating system institutions. This qualitative phenomenological study focused on critical analysis classroom practices with reference to 21st century learners’ competencies and techniques.The data were collected from 12 faculty members Department Mathematics Education, Centra...

Emerging evidence suggests that the tendency to generate stressful life events may be, at least in part, genetically determined. However, the role of the early environment in shaping responses to later stressors is crucial to fully specifying biogenetic models of stress generation. The current study examined the moderating role of childhood emotional, physical, and sexual maltreatment on the re...

results at follow-up, the nonoperatively treated patients had better functional outcomes than the operatively treated patients. nonoperatively treated patients also scored better on pain intensity and satisfaction. there were no significant differences in cesd, pcs, and sf-36 physical- and mental health summary scores between cohorts. conclusions the results of this study suggest that operative...

one of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (lm) andtransmission electron microscopy (tem). for the lm study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. sections were stained with orcein. for the tem stud...
