CONTEXT A top-down evaluation of the costs of operating rooms (ORs) is not commonly done because it is relevant mostly in a publicly funded system. OBJECTIVE This study was conducted to determine the costs and utilization of ORs in a public hospital in Trinidad, West Indies, for two one-year periods using a top-down model. DESIGN Quantitative observational study.Main Outcome Measures: A "co...

Abstract Noses are extremely sophisticated chemical detectors allowing animals to use scents interpret and navigate their environments. Odor detection starts with the activation of odorant receptors (ORs), expressed in mature olfactory sensory neurons (OSNs) populating mucosa. Different odorants, or different concentrations same odorant, activate unique ensembles ORs. This mechanism combinatori...

At present, laminar airflow (LAF) systems and mixing ventilation (MV) are two commonly used solutions for operating rooms (ORs) to ensure the required indoor air quality. However, recent studies have shown that there is little difference in prevalence of surgical site infection (SSI) LAF MV systems. The objective this study was compare performance an system with ORs at St. Olavs hospital, Norwa...

In this paper we are proposing a general framework for the analysis of the complete set of log Odds Ratios (ORs) generated by a two-way contingency table. Starting from the RC (M) association model and hypothesizing a Poisson distribution for the counts of the two-way contingency table we are obtaining the weighted Log Ratio Analysis that we are extending to the study of log ORs. Particularly w...

The addition of different organic substrates to standard glucose oral rehydration solution (G-ORS) has been shown to improve the intestinal absorption of sodium and water, and thereby decrease stool losses. Therefore, we evaluated, in infants with acute diarrhoea, the safety and efficacy of three oral rehydration solutions (ORS) which had the same concentrations of electrolytes (with sodium 60 ...

HYPOTHESIS Three parallel processing operating rooms (ORs) (concurrent induction and turnover) with a dedicated 3-bed mini-recovery room (mini-postanesthesia care unit [PACU]) will optimize patient throughput and main PACU workload when compared with 4 traditional ORs or 4 parallel processing ORs. DESIGN Statistical and mathematical models projected the impact of parallel processing on case t...

Objective: To assess knowledge, attitude and practices of mothers on the use of ORS in diarrhoea in children Method: This cross-sectional KAP study was conducted in the Department of Paediatrics, Dar-ulSehat hospital, Karachi from February 2015 to 30 April 2015. Sampling type was non-probability convenience and the sample size was 200. Mothers who were local residents, opted for participation i...

The identification of orientation relationships (ORs) plays a crucial role in the understanding of solid phase transformations. In steels, the most common models of ORs are the ones by Nishiyama-Wassermann (NW) and Kurdjumov-Sachs (KS). The defining feature of these and other OR models is the matching of directions and planes in the parent face-centred cubic γ phase to ones in the product body-...

A total of 595 respondents (200 from urban Kachi-abadis and 395 from rural communities of Rawalpindi-Islamabad) were interviewed for their knowledge about the use of ORS (Nimkol) in childhood diarrhoea. Most of the respondents were mothers with low literacy rate (23%). The prevalence of current diarrhoea among children was 36.8% on the day of interview whereas 57% of the children had history of...

Transport of G protein-coupled receptors (GPCRs) to the cell surface membrane is critical in order for the receptors to recognize their ligands. However, mammalian GPCR odorant receptors (ORs), when heterologously expressed in cells, are poorly expressed on the cell surface. Here we show that the transmembrane proteins RTP1 and RTP2 promote functional cell surface expression of ORs expressed in...
