Historically, pen lifts have been considered valuable predictors of simulation behaviour. Despite this belief, there exists only limited empirical data available to characterise the extent to which unexpected pen lifts contribute to evidence in support of simulation behaviour. This study was devised to examine the frequency with which pen-lifts are observed in a population of 2280 simulated sig...

BACKGROUND Partial enteral nutrition (PEN) may be helpful for the maintenance of remission in pediatric Crohn's disease patients. AIMS To evaluate the efficacy of PEN treatment for preventing clinical relapse. METHODS We retrospectively assessed 42 pediatric Crohn's disease patients who entered clinical remission on 4-12 weeks of exclusive enteral nutrition (EEN) and were maintained on PEN ...

twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. treatments consisted of 8 (t1), 4 (t2) or 2 (t3) feeding buckets/pen (8 lambs/pen). during the experiment, concentrate was fed at 08:30 in individual feeders. daily dry matter intake (dmi...

Artificial light can change the behaviour of aquatic organisms, although the direction of response can be species and life-stage specific. Open net-pen salmon farms in British Columbia, Canada, routinely illuminate their net-pens during the winter and spring, with unknown consequences on the abundance and distribution of marine fish and invertebrates. Paired lit and control samples consisting o...

Commodity polyester plastics such as PET, PBT, and PEN are hydrogenolytically deconstructed to their starting monomeric carboxylic acids light alkanes using a solventless tandem catalytic approach with two air- moisture-stable catalysts, Hf(OTf)4 Pd/C. These selective reactions operate near the polymer melting temperature under 1 atm H2 compatible mixed plastics, reported by Yosi Kratish Tobin ...

Allergenic serine proteases are important in the pathogenesis of asthma. One of these, Pen c 13, is the immunodominant allergen produced by Penicillium citrinum. Many serine proteases induce cytokine expression, but whether Pen c 13 does so in human respiratory epithelial cells is not known. In this study, we investigated whether Pen c 13 caused IL-8 release and activated protease-activated rec...

In each of three trials, 240 crossbred barrows weaned at 17 d of age (5.1 kg BW) were assigned to one of three experimental treatments based on light and heavy weight outcome groups. Experimental treatments were 1) wean-to-finish at 0.69 m2/pig and 15 pigs/pen; 2) wean-to-finish double-stocked at 0.35 m2/pig, 30 pigs per pen for 8 wk and then randomly split into two pens (either stayed in same ...
