Adventure-based mindsets helped maintain psychological well-being during COVID-19.

Objectives: Research conducted during the COVID-19 pandemic underscores the value of physical activity and nature for psychological well-being in the general population when people's mobility and activities are restricted due to government mandates. Since restrictions may thwart the psychological benefits reported from participation in adventure recreation (e.g.

In the Palm of Your Hand - Normalizing the Use of Mobile Technology for Nurse Practitioner Education and Clinical Practice.

The use of mobile devices by nurse practitioners (NPs) to meet an evolving technological landscape is expanding rapidly. A longitudinal study of the ways NP students "normalize" the use of mobile devices in clinical education was completed. This study used researcher-designed survey tools, including sociodemographic questions, and the numerical picture was augmented and interpreted in light of the textual data in the form of selected interviews.

Safety assessment of EPA-rich triglyceride oil produced from yeast: genotoxicity and 28-day oral toxicity in rats.

The 28-day repeat-dose oral and genetic toxicity of eicosapentaenoic acid triglyceride oil (EPA oil) produced from genetically modified Yarrowia lipolytica yeast were assessed. Groups of rats received 0 (olive oil), 940, 1880, or 2820 mg EPA oil/kg/day, or fish oil (sardine/anchovy source) by oral gavage. Lower total serum cholesterol was seen in all EPA and fish oil groups.

Safety assessment of EPA-rich oil produced from yeast: Results of a 90-day subchronic toxicity study.

The safety of eicosapentaenoic acid (EPA) oil produced from genetically modified Yarrowia lipolytica yeast was evaluated following 90 days of exposure. Groups of rats received 0 (olive oil), 98, 488, or 976 mg EPA/kg/day, or GRAS fish oil or deionized water by oral gavage. Rats were evaluated for in-life, neurobehavioral, anatomic and clinical pathology parameters.

Subchronic feeding study with genetically modified stacked trait lepidopteran and coleopteran resistant (DAS-Ø15Ø7-1xDAS-59122-7) maize grain in Sprague-Dawley rats.

DAS-Ø15Ø7-1xDAS-59122-7 (1507x59122) is a genetically modified (GM) maize hybrid that was produced by crossing of two GM maize inbreds; DAS-Ø15Ø7-1 and DAS-59122-7. This hybrid cross expresses four transgenic proteins: Cry1F and PAT (from DAS-Ø15Ø7-1) and Cry34Ab1/Cry35Ab1 and PAT (from DAS-59122-7) that confer resistance to lepidopteran and coleopteran pests and tolerance to the herbicidal active ingredient glufosinate-ammonium. The current subchronic feeding study was conducted in Sprague-Dawley rats to evaluate the potential health effects of long-term consumption of a rodent diet containing 1507x59122 maize grain compared with a diet containing maize grain from its near-isogenic control (091).

Work injuries.

Objectives: This article compares work injury occurrence by occupational category, and examines its relationship with selected factors reflecting work organization and environment. Associations between work injury and socio-demographic and other health-related variables are also considered.

Data Sources: Data are from the 2003 Canadian Community Health Survey (cycle 2.

Thirteen week feeding study with transgenic maize grain containing event DAS-Ø15Ø7-1 in Sprague-Dawley rats.

Maize line 1507, containing event DAS-Ø15Ø7-1 (1507), is a genetically modified (GM) maize plant that expresses the cry1F gene from Bacillus thuringiensis (Bt) sbsp. aizawai and the phosphinothricin-N-acetyltransferase (pat) gene from Streptomyces viridochromogenes throughout the plant including in the grain expression of the Cry1F protein confers in planta resistance to the European corn borer (ECB; Ostrinia nubilalis Hübner: Crambidae) and other lepidopteran pests. Expression of the PAT protein confers tolerance to the herbicidal active ingredient glufosinate-ammonium.

Antioxidant metabolism during acclimation of Begonia x erythrophylla to high light levels.

This study examined the influence of high light levels on antioxidant metabolism and the photosynthetic properties of Begonia x erythrophylla leaves. The pigment composition of shaded leaves and those developing in full sunlight was typical of shade- and sun-leaves, respectively. After 28 d in full sunlight, the preformed leaves of shade plants transferred to full sunlight (transferred-leaves) showed photo-bleaching with lower Chl (a + b) content and Chl a : Chl b ratios than shade-leaves, with Chl (a + b) : carotenoid ratios not significantly different.
