    The purpose of this research was to determine if the effectiveness of technology education can be significantly increased through use of team-based activities including both real-time team encounters and results-driven team assignments. The research addresses this purpose by examining perceptions regarding effectiveness of team-based learning in several degree programs in Information Technology education. Survey data was gathered from adult students about their experience with recent team assignments. All participants were enrolled at a large private non-profile university on the west coast within the School of Engineering, Technology and Media. The Team Work Survey was administered and hosted on the Survey Monkey website and released to about 200 courses in programs for a Bachelor of Science or a Master of Science degree. Over four periods, survey responses were returned for 96 learners enrolled in undergraduate courses and 126 learners enrolled in graduate courses. The researcher was granted permission by DiFonzo (2010) to use a survey instrument adapted and piloted that was based on an earlier Team Performance Survey originated by Peters (1997) who developed, validated and determined its reliability. Several comparisons were made using statistical analysis to determine the interesting patterns relevant to this research. The interpretation of findings included evidence that team effectiveness was indeed positively aligned with team members' perceptions about ability to learn, with their interest in the topic and the motivation of individual members to commit time and energy to the team assignments

    Rifampicin, not vitamin E, suppresses parenteral nutrition-associated liver disease development through the pregnane X receptor pathway in piglets

    Infants receiving long-term parenteral nutrition (PN) develop PN-associated liver disease (PNALD). We previously (Ng K et al. JPEN J Parenter Enteral Nutr 40: 656 - 671, 2016. doi: 10.1177/0148607114567900.) showed that PN containing soy-based lipid supplemented with vitamin E (alpha-tocopherol) prevents the development of PNALD. We hypothesize that this occurs via vitamin E activation of pregnane X receptor (PXR)-mediated pathways involved in bile acid metabolism. Neonatal piglets received PN for 14 days containing Intralipid (IL; soy-based lipid emulsion), IL supplemented with 12.6 mg.kg(-1).day(-1) vitamin E (VITE), or IL with 10 mg.kg(-1).day(-1) Rifadin IV (RIF), a PXR agonist. Pigs treated with IL and VITE, but not RIF, developed cholestasis and hyperbilirubinemia, markers of liver disease. The hepatic PXR target genes CYP3A29 and UGT1A6 increased during RIF treatment. RIF also modestly increased metabolism of chenodeoxycholic acid to the more hydrophilic bile acid hyocholic acid. Serum fibroblast growth factor (FGF)-19, a key regulator in suppressing hepatic bile acid synthesis, significantly increased in the RIF group. We conclude rifampicin modified markers of PNALD development by increased metabolism of bile acids and potentially suppressed bile acid synthesis. Vitamin E was ineffective at high lipid doses in preventing PNALD.NEW &amp; NOTEWORTHY Intravenous vitamin E and rifampicin were administered to neonatal piglets receiving parenteral nutrition to determine their efficacy in reducing the progression of parenteral nutrition-associated liver disease (PNALD). Rifampicin increased serum FGF-19 concentrations and synthesis of the bile acid hyocholic acid which led to a reduction of PNALD parameters at 2 wk of administration. This result has potential clinical implications for the use of rifampicin as a safe and inexpensive treatment for short-term development of PNALD.</p
