Inadvertent hypothermia can have significant consequences in the perioperative setting. Knowing how to recognize and manage inadvertent hypothermia is an important aspect of perioperative nursing. A quantitative, descriptive study was conducted at an annual perioperative nursing conference to evaluate nurses' knowledge regarding the prevention of inadvertent perioperative hypothermia. Significant variations in responses regarding definitions of hypothermia and normothermia were noted. In addition, nurses identified a plethora of factors that prevent them from maintaining normothermia in their patients. These factors mandate a need for educational interventions and the adoption of practice guidelines in the clinical area.

Isoflavones are naturally occurring compounds found in soybean [Glycine max (L.) Merr.]. Soybean isoflavone, as a quantitative trait, is subject to significant genotype × environment interaction, which makes breeding for this trait difficult. Thirty F4:7 soybean lines, derived from crosses of ‘RCAT Angora’ × CK‐01 and ‘Heinong 35’ × RCAT Angora were classified within each population as high, intermediate, or low isoflavone. The lines, parents, and two maturity checks were grown in four locations in 2005 and six locations in 2006 across Ontario and Quebec, Canada. Isoflavone content of the mature seed was determined by near‐infrared reflectance. The effects of genotype, environment, and the genotype × environment (G × E) interaction were significant. Consistently performing genotypes from the two populations were identified by several stability parameters. Genotype–genotype × environment (GGE) biplot demonstrated an ability to provide information on both the genotypes and the environments in which they were evaluated. The identification of genotypes with consistent placement in either the high‐ and low‐isoflavone classes suggested that breeding for relative isoflavone content in soybean is possible, although breeding for absolute stability remains a challenge, given the large environmental influence on soybean isoflavone levels.

. 2009. Association of seed and agronomic traits with isoflavone levels in soybean. Can. J. Plant Sci. 89: 477Á484. Soybean, Glycine max (L.) Merr., seeds contain isoflavones, compounds with potential human health benefits. This study investigated the association of seed and agronomic traits with isoflavone level in a genetically diverse group of soybean genotypes to provide more information for cultivar development. F 4:7 lines derived from several crosses were grown in four locations in 2005 and six locations in 2006 across Ontario and Quebec. Seed protein, oil and isoflavone contents were measured using near-infrared reflectance (NIR) on a plot basis. Seed yield was determined at 13% moisture and days to maturity (R8) were recorded. GGE genotype-bytrait biplots were generated to describe the relationships among all variables. Isoflavone content was not correlated with yield, indicating that potential exists for development of high or low isoflavone cultivars without sacrificing yield. Isoflavone content was negatively correlated with protein content, however high isoflavone lines were identified with moderate protein content. Isoflavone content was correlated with maturity suggesting that delayed planting and/or the use of later maturing varieties could be a successful strategy to increase isoflavone content. The results of this study support the potential for the development of either high or low isoflavone soybean cultivars with acceptable agronomic and seed quality traits.Key words: Soybean, isoflavone, protein, oil, yield, maturity Murphy, S.

Plant Sci. 89: 477Á484. Les graines du soja, Glycine max (L.) Merr., contiennent des isoflavones, compose´susceptible d'avoir des effets be´ne´fiques sur la sante´. L'e´tude examinait les liens qui existent entre la concentration d'isoflavones et les caracte`res grainiers et agronomiques dans un groupe de varie´te´s de soja ge´ne´tiquement varie´, dans le but de fournir plus d'informations en vue de cre´er de nouveaux cultivars. Les ligne´es F 4:7 issues de plusieurs croisements ont e´te´cultive´es a`quatre endroits en Ontario et au Que´bec, en 2005, et a`six, en 2006. La teneur en prote´ines, en huile et en isoflavones des graines a e´te´e´tablie par re´flectance dans le proche infrarouge, dans les parcelles. Le rendement grainier a e´te´mesure´a`13 % de teneur en eau et on a enregistre´le nombre de jours jusqu'a`maturite´(R8). L'analyse GGE par double projection du ge´notype et des caracte`res a permis de de´crire les liens entre les variables. La concentration d'isoflavones n'est pas corre´le´e au rendement, signe qu'on pourrait cre´er des cultivars a`faible ou a`forte concentration d'isoflavones sans que le rendement en souffre. La concentration d'isoflavones pre´sente une corre´lation ne´gative avec la teneur en prote´ines, mais les ligne´es produisant beaucoup d'isoflav...
