Intravenous ketamine and lidocaine infusions may be useful adjuncts to inhalation anesthesia for sheep undergoing orthopedic surgery. In this study, 50 female sheep underwent experimental stifle surgery (29 received a meniscal implant and 21 received sham surgery). To induce anesthesia in the sheep, the authors intravenously injected ketamine and diazepam. They administered isoflurane in oxygen to maintain anesthesia and used mechanical ventilation to maintain normal arterial carbon dioxide pressure. Some sheep received intravenous infusions of ketamine and lidocaine during surgery, whereas others did not. Sheep that received a meniscal implant without ketamine-lidocaine required ∼23% greater isoflurane concentrations than sheep that were given ketamine-lidocaine. These findings suggest that intravenous infusion of ketamine and lidocaine decreases the requirement for isoflurane during orthopedic surgery on anesthetized sheep. Source

This paper describes a methodology for creating concept inventories that can be used to validly and reliably measure student misconceptions in engineering and science domains. Following the successful impact of the Force Concept Inventory on undergraduate physics education, creating concept inventories in engineering subjects provides engineering faculty and researchers with tools for measuring the effect of new curricular and pedagogical tools that are designed to repair misconceptions. The methodology involved aligning the three corners of the assessment triangle: cognition, observation, and interpretation. In the cognition corner, engineering students' important misconceptions in thermal science were identified using a Delphi study and validated with current learning theory. In the observation corner, items for the TTCI were created and piloted. In the interpretation corner, classical test theory and item response theory were used to evaluate the performance of TTCI items and establish instrument reliability. Versions of the TTCI have been developed for heat transfer, thermodynamics, and fluid mechanics and piloted to over 1000 undergraduate engineering students. The heat transfer portion of the instrument consists of 12 items with an overall KR-20 reliability of 0.77. Item difficulty indices range from 0.25 to 0.75 and item discrimination index exceeds 0.20 for each item. These values are sufficient for using the TTCI as a tool to identify students' misconceptions in thermal and transport science in two ways: (1) as an informal classroom assessment or (2) to establish pre-test/post-test learning gains during a course of study. © 2011 TEMPUS Publications.

Several species of fungi exploit ants. Most of them are known from the tropics, where they may exhibit spectacular morphologies, and a handful of species are known to occur in Europe. Available data on their geographic range, host specificity and effect on the host is scarce and require acquisition. In addition, there is a significant geographic bias in the available data: mostly Western and Central European records are known. Herein, we provide an overview of the myrmecoparasitic fungal species from a hitherto barely explored country, Romania: Aegeritella superficialis Balazy et J. Wisn. (1974), Myrmicinosporidium durum Hölldobler, 1933, Pandora myrmecophaga (Turian et Wuest) S. Keller (2005) and Rickia wasmannii Cavara (1899) are presented. P. myrmecophaga is reported for the first time in Romania, and several new locations for R. wasmannii are given, and also a new host species for the fungus. General aspects of the biology of the four species, their distribution in Romania and their host range are presented. © NwjZ, Oradea, Romania, 2013. Source

Catholic, Jewish and Protestant clergy (n = 801) completed a survey to identify predictors of clergy's ability to fulfill a suicide gatekeeper role. Exploratory backward stepwise regression identified predictors of risk identification including suicide knowledge, religion, conducting suicide funerals, having an attitude that people have a right to die, age, and race. Predictors of ability to intervene include suicide knowledge, training, religion, right to die attitude, and ethnicity. Recommendations include more suicide training and clergy self-care. © The Author(s) 2016. Source

The goal of this study was to determine the composition and diversity of microorganisms associated with bioaerosols in a heavily trafficked metropolitan subway environment. We collected bioaerosols by fluid impingement on several New York City subway platforms and associated sites in three sampling sessions over a 1.5-year period. The types and quantities of aerosolized microorganisms were determined by culture-independent phylogenetic analysis of small-subunit rRNA gene sequences by using both Sanger (universal) and pyrosequencing (bacterial) technologies. Overall, the subway bacterial composition was relatively simple; only 26 taxonomic families made up~75% of the sequences determined. The microbiology was more or less similar throughout the system and with time and was most similar to outdoor air, consistent with highly efficient air mixing in the system. Identifiable bacterial sequences indicated that the subway aerosol assemblage was composed of a mixture of genera and species characteristic of soil, environmental water, and human skin commensal bacteria. Eukaryotic diversity was mainly fungal, dominated by organisms of types associated with wood rot. Human skin bacterial species (at 99% rRNA sequence identity) included the Staphylococcus spp. Staphylococcus epidermidis (the most abundant and prevalent commensal of the human integument), S. hominis, S. cohnii, S. caprae, and S. haemolyticus, all well-documented human commensal bacteria. We encountered no organisms of public health concern. This study is the most extensive culture-independent survey of subway microbiota so far and puts in place pre-event information required for any bioterrorism surveillance activities or monitoring of the microbiological impact of recent subway flooding events. © 2013, American Society for Microbiology.
