Looking Beyond the Growth Curve: A Retrospective Study on Nutrient Deficient Diets in Children with Severe Food Selectivity.

Severe food selectivity places children at risk for nutrient deficiencies and long-term medical complications, if unaddressed. However, poor nutrition in highly selective eaters is often overlooked when considering other behavioral or medical concerns. Additionally, studies regarding food selectivity are sparse and limited to children with developmental delays.

A confirmed case of agranulocytosis after use of cocaine contaminated with levamisole.

More than 2 million Americans use cocaine each month (National Survey on Drug Use and Health, Department of Health and Human Services: Substance Abuse and Mental Health Services Administration (SAMHSA) & Office of Applied Studies (OAS), Rockville, MD 2007). Starting in early 2003, South American cocaine cartels began to add levamisole, a pharmaceutical agent, to bulk cocaine prior to shipment to the USA (Valentino and Fuentecilla 2005). A dramatic increase in the prevalence of levamisole in cocaine was noted in early 2008.

A conceptual model for growing evidence-based practice.

Nursing administration at a small medical center is developing and implementing an evidence-based practice (EBP) model of care to support a culture of quality care, clinical excellence, cost-effectiveness, critical thinking, empowerment of staff, and professional growth. The purpose of this article is to describe a conceptual model for EBP that addresses how to overcome barriers to implementation. Clinician expertise and values, experience, patient preference and expectation, and caring become grounded in a practice environment that must strive to become rooted in clinical research to evolve into a practice that is evidence-based.

A genetic reporter of thermal stress defines physiologic zones over a defined temperature range.

We define five unique cellular responses to thermal stress using a reporter construct generated using the stress-inducible promoter from the gene encoding a murine 70 kDa heat shock protein (Hsp70A.1) to express luciferase (luc). Thermal stress was delivered over a range of temperatures (42-68 degrees C) for 5 s to 20 min and luciferase activity was measured in live cells using a cooled CCD camera as a measure of reporter gene transcription.

New SO(2) Iron-Containing Cluster Compounds [PPN](2)[Fe(3)(CO)(9)(&mgr;(3),eta(2)-SO(2))], [PPN](2)[Fe(3)(CO)(8)(&mgr;-SO(2))&mgr;(3)-S], [PPN](2)[Fe(3)(CO)(8)(&mgr;-SO(2))(&mgr;(3)-CCO)], and [PPN](2)[Fe(2)(CO)(6)(&mgr;-SO(2))(2)] from Heterometal Precursors.

Sulfur dioxide reacts with [PPN](2)[MFe(3)(CO)(14)] (M = Cr, Mo, W) (PPN = bistriphenylphosphonium iminium) to produce [PPN](2)[Fe(3)(CO)(9)(&mgr;(3),eta(2)-SO(2))] (I) and [PPN](2)[Fe(3)(CO)(8)(&mgr;-SO(2))&mgr;(3)-S] (II), which were characterized by infrared spectroscopy, (13)C NMR, and X-ray crystallography. Further reaction of I with sulfur dioxide results in the formation of II in 48% yield. Reaction of SO(2) with [PPN](2)[Fe(4)(CO)(13)] yields [PPN](2)[Fe(2)(CO)(6)(&mgr;-SO(2))(2)] (III) which was characterized by infrared spectroscopy, (13)C NMR, mass spectrometry, and X-ray crystallography.
