STUDY OBJECTIVE To study the effectiveness of an anesthesiologist-directed preadmission evaluation center (PEC) in our institution. DESIGN I: Preoperative test costs were measured on two sets of patients undergoing same-day surgery. II: Rate of cancellation was measured on all patients undergoing same-day surgery in a subsequent one-year time period. SETTING The PEC, short procedure unit, a...

The effects of partial replacement of Cu with Ag in a Cu(In,Ga)S2 (CIGS) thin film on its structural, optical, electrostructural, and photoelectrochemical (PEC) properties were investigated, in order to improve its performance for PEC water reduction under sunlight illumination. Results from X-ray diffraction (XRD) analyses revealed the successful partial replacement of Cu with Ag to form solid...

A PEC is a Pattern Enforcing Compiler, which is like a conventional compiler only extended to include the extra checks needed to enforce design patterns. PECs are currently a research project and the PEC written is targeted at the Java programming language. This paper:

Three building blocks of the antenna complexes of the cyanobacterium Westiellopsis prolifica were studied: PEC(X), which is similar to the ot-subunit of phycoerythrocyanin (PEC), trimers of PEC and monomers derived from these by deaggregation with KSCN. The fit of the fluorescence decay curve of PEC(X) requires at least four exponentials, although it supposedly contains only one chromophore. Th...

preformulation studies on transdermal dosage forms involve liberal use of animal skin for assessing the permeation characteristics of drugs, influence of permeation enhancers, optimizing the formulation variables etc. the restricted availability of animal skin due to concerns regarding prevention of cruelty to animals has generated considerable interest in developing polymeric films for use as ...

BACKGROUND TRPV1 is a ligand-gated ion channel whose activation by capsaicin increases intracellular Ca(2+) ([Ca(2+)](i)). TRPV1 and cannabinoid CB(1) receptor activation are capable of eliciting analgesia. In this study, using recombinant human (h) and rat (r) TRPV1 receptors expressed in HEK293 cells, we have performed a comparison of both TRPV1 species at 22 and 37 degrees C and compared end...

Single pancreatic endocrine cells (PEC) have been demonstrated to restore normoglycemia when transplanted intracerebrally in diabetic rat recipients across a major histocompatibility barrier without immunosuppression. Twelve out of twelve transplants of purified PEC have achieved long-term survival of over 176 days. This approach would provide a model to identify the specific cell(s) as inducer...
