Sustainable Diagram on Food Waste Reduction Programs in Mitigating Carbon Footprint—a Loyola Marymount University Case Study
Food waste is an economic, social, and environmental problem with broad implication. The direct impacts from fossil fuel use, food waste rotting in landfills, water use, and transferring food waste create environmental stressors associated with climate change. Increasing methods to reduce food waste are becoming common practice across private sector as a tool to reduce economic cost and carbon footprint. This study aims to evaluate the food waste diversion efforts at Loyola Marymount University’s dining hall. The research approach examining Loyola Marymount dining halls’ sustainability efforts will be broken down into two separate stages: analyzing food waste data pre- and post-implementation of mitigation efforts, and diagramming the mitigation efforts including the composting, liquefying, and dehydrator processes. This study hopes to demonstrate how a university’s efforts to reduce food waste can contribute to the overall goal of sustainability. Using diagrams to relay findings, this study can serve as encouragement to LMU to continue and increase sustainability efforts, and as a model for other universities.https://digitalcommons.lmu.edu/cures_posters/1027/thumbnail.jp
Over het multipel myeloom, het solitaire plasmocytoom en de macroglobulinaemie:klinische, histologische, biochemische en serologische waarnemingen
In 1949 zagen wij kort na elkaar twee patienten met multipel myeloom. Het viel ons toen op, dat het aspect van de myeloomcellen in het beenmergpunctaat van deze twee patienten sterk uiteenliep. In de loop van de volgende vijf jaren hebben wij gegevens verzameld over 47 patienten, van wie 40 lijdende waren aan de klassieke vorm van multipel myeloom en de overige 7 aan één van de varianten ervan, zoals het solitaire plasmocytoom en de macroglobulinaemie. ....

Effects of grazing management on biodiversity across trophic levels–The importance of livestock species and stocking density in salt marshes
European coastal salt marshes are important for the conservation of numerous species of specialist plants, invertebrates, breeding and migratory birds. When these marshes are managed for nature conservation purposes, livestock grazing is often used to counter the dominance of the tall grass Elytrigia atherica, and the subsequent decline in plant species richness. However, it remains unclear what is the optimal choice of livestock species and stocking density to benefit biodiversity of various trophic levels. To fill this knowledge gap, we set up a triplicate, full factorial grazing experiment with cattle and horse grazing at low and high stocking densities (0.5 or 1 animal ha−1) at the mainland coast of the Dutch Wadden Sea. Here, we present the results after 4 years and integrate these with previously published results from the same experiment to assess effects of livestock grazing on various trophic groups. Stocking density affected almost all measured variables: high stocking densities favoured plant species richness and suppression of E. atherica, whereas low stocking densities favoured abundances of voles, pollinators and flowers. Densities of different functional groups of birds showed no significant response to the regimes, but tended to be somewhat higher under 0.5 horse and 1 cattle ha−1. Choice of livestock species had fewer and smaller effects than stocking density. Horse grazing was detrimental to vole density, and showed an interactive effect with stocking density for Asteraceae flower abundance. Multidiversity, a synthetic whole-ecosystem biodiversity measure, did not differ among regimes. These results are discussed in the light of other results from the same experiment. Because of these contrasting effects on different trophic groups, we advise concurrent application of different grazing regimes within a spatial mosaic, with the inclusion of long-term abandonment. High density horse grazing, however, is detrimental to biodiversity
Differences between Physostigmine- and Yohimbine-induced States Are Visualized in Canonical Space Constructed from EEG during Natural Sleep-wake Cycle in Rats
Although quantitative EEG parameters, such as spectral band powers, are sensitive to centrally acting drugs in dose- and time-related manners, changes of the EEG parameters are redundant. It is desirable to reduce multiple EEG parameters to a few components that can be manageable in a real space as well as be considered as parameters representing drug effects. We calculated factor loadings from normalized values of eight relative band powers (powers of 0.5, 1.0~2.0, 2.5~4.0, 4.5~5.5, 6.0~8.0, 8.5~12.0, 12.5~24.5, and 25~49.5 Hz bands expressed as ratios of the power of 0.5-49.5 Hz band) of EEG during pre-drug periods (11:00~12:00) by factor analysis and constructed a two-dimensional canonical space (reference canonical space) by canonical correlation analysis. Eight relative band powers of EEG produced by either physostigmine or yohimbine were reduced to two canonical scores in the reference canonical space. While changes of the band powers produced by physostigmine and yohimbine were too redundant to describe the difference between two drugs, locations of two drugs in the reference canonical space represented the difference between two drug's effects on EEG. Because the distance between two locations in the canonical space (Mahalanobis distance) indicates the magnitude of difference between two different sets of EEG parameters statistically, the canonical scores and the distance may be used to quantitatively and qualitatively describe the dose-dependent and time-dependent effects and also tell similarity and dissimilarity among effects. Then, the combination of power spectral analysis and statistical analysis may help to classify actions of centrally acting drugs

A comparison of the respiratory effects of oxycodone versus morphine: a randomised, double-blind, placebo-controlled investigation
Oxycodone’s respiratory profile (particularly the extent of respiratory depression in comparison to morphine) remains to be fully characterised in the peri-operative period. We randomly assigned ASA 1-2 adults for elective surgery under general anaesthesia to receive saline, morphine 0.1 mg.kg−1, or oxycodone 0.05 mg.kg−1, 0.1 mg.kg−1, or 0.2 mg.kg−1. Results were obtained from six patients in the saline group, 12 patients in the groups receiving morphine 0.1 mg.kg−1, oxycodone 0.05 mg.kg−1 and 0.1 mg.kg−1, and from 10 patients who received oxycodone 0.2 mg.kg−1. Patients were breathing spontaneously and minute ventilation monitored with a wet wedge spirometer for 30 min. All active groups demonstrated significant respiratory depression compared to saline (p < 0.0001 for all groups). The mean (SD) reduction in minute volume from baseline was 22.6% (10.4%) for the morphine 0.1 group and 53.3% (27.2%), 74.4% (12.9%) and 88.6% (13.5%) for the oxycodone 0.05, 0.1 and 0.2 groups, respectively, with significant dose dependent differences between oxycodone groups (p = 0.0007). The extent and speed of onset of oxycodone induced respiratory depression was dose dependent and greater than an equivalent dose of morphine
Influence of pharmacogenetic variability on the pharmacokinetics and toxicity of the aurora kinase inhibitor danusertib
Objectives Danusertib is a serine/threonine kinase inhibitor of multiple kinases, including aurora-A, B, and C. This explorative study aims to identify possible relationships between single nucleotide polymorphisms in genes coding for drug metabolizing enzymes and transporter proteins and clearance of danusertib, to clarify the interpatient variability in exposure. In addition, this study explores the relationship between target receptor polymorphisms and toxicity of danusertib. Methods For associations with clearance, 48 cancer patients treated in a phase I study were analyzed for ABCB1, ABCG2 and FMO3 polymorphisms. Association analyses between neutropenia and drug target receptors, including KDR, RET, FLT3, FLT4, AURKB and AURKA, were performed in 30 patients treated at recommended phase II dose-levels in three danusertib phase I or phase II trials. Results No relationships between danusertib clearance and drug metabolizing enzymes and transporter protein polymorphisms were found. Only, for the one patient with FMO3 18281AA polymorphism, a significantly higher clearance was noticed, compared to patients carrying at least 1 wild type allele. No effect of target receptor genotypes or haplotypes on neutropenia was observed. Conclusions As we did not find any major correlations between pharmacogenetic variability in the studied enzymes and transporters and pharmacokinetics nor toxicity, it is unlikely that danusertib is highly susceptible for pharmacogenetic variation. Therefore, no dosing alterations of danusertib are expected in the future, based on the polymorphisms studied. However, the relationship between FMO3 polymorphisms and clearance of danusertib warrants further research, as we could study only a small group of patients
