    Eudora Welty and Flannery O\u27Connor are two southern authors who are well-known among American Literature enthusiasts. Although their overall tones and styles are not often very similar, they definitely had similar expectations of and explanations for how they wrote. Not only did Welty and O\u27Connor impart to the literary world a variety of fictional works, they also wrote essays, letters, and introductions which provide background information about their own framework of time and place, the relational conflicts within their fiction, and the importance of figurative language in literary art. Though they were sixteen years apart in age and came from different states, they had similar backgrounds in that they both originally planned careers involving the visual arts. For Welty, that medium was photography; for O\u27Connor, that medium was cartooning. Looking at both their visual arts and their fiction, the audience will find that their tones, though different between the two authors, are consistent within their media. Welty\u27s photographs and her fiction convey a positive and lighthearted tone while O\u27Connor\u27s cartoons as well as her fiction display a satirical tone. By comparing their works, the audience will see how each author\u27s tone is consistently conveyed through her various arts while also seeing how their differing tones are reflected through their fiction. Such information will show the importance of the authors\u27 visual arts in grasping a full understanding of the context of their writing

    The purpose of the study was to test the effectiveness of an interprofessional collaborative practice (IPCP) education program on clinicians\u27 and students\u27 knowledge and attitudes toward IPCP and to determine the effectiveness of an IPCP weight loss program in two nurse-managed centers. The study team used the Midwest Interprofessional Practice, Education, and Research Center (MIPERC) collaborative practice education program that consists of online learning modules followed by daily huddles and collaborative care planning. The obesity intervention program was implemented by faculty and staff practitioners and students in two clinics with very different patient populations (community residents and college students). Staff/faculty practitioners and students demonstrated statistically significant knowledge gains as a result of online learning modules (Introduction to IPE p \u3c .05; Motivational Interviewing p \u3c .001; Safety Behaviors p \u3c .001; Team Dynamics p \u3c .001). Small, but not statistically significant changes in attitudes toward IPCP were seen with both groups. At program completion, enrolled patients showed statistical significant (p \u3c .001) weight losses and decreases in body mass indices. Other health outcomes showed no significant changes (blood pressure, prevalence of smoking, exercise frequency or duration p \u3e .05). The study demonstrated the potential of an IPCP program to affect weight loss in two populations

    Background: The main goal of the present study was to analyse the genetic architecture of mRNA expression in muscle, a tissue with an outmost economic importance for pig breeders. Previous studies have used F2 crosses to detect porcine expression QTL (eQTL), so they contributed with data that mostly represents the between-breed component of eQTL variation. Herewith, we have analysed eQTL segregation in an outbred Duroc population using two groups of animals with divergent fatness profiles. This approach is particularly suitable to analyse the within-breed component of eQTL variation, with a special emphasis on loci involved in lipid metabolism. Methodology/Principal Findings: GeneChip Porcine Genome arrays (Affymetrix) were used to determine the mRNA expression levels of gluteus medius samples from 105 Duroc barrows. A whole-genome eQTL scan was carried out with a panel of 116 microsatellites. Results allowed us to detect 613 genome-wide significant eQTL unevenly distributed across the pig genome. A clear predominance of trans- over cis-eQTL, was observed. Moreover, 11 trans-regulatory hotspots affecting the expression levels of four to 16 genes were identified. A Gene Ontology study showed that regulatory polymorphisms affected the expression of muscle development and lipid metabolism genes. A number of positional concordances between eQTL and lipid trait QTL were also found, whereas limited evidence of a linear relationship between muscle fat deposition and mRNA levels of eQTL regulated genes was obtained. Conclusions/Significance: Our data provide substantial evidence that there is a remarkable amount of within-breed genetic variation affecting muscle mRNA expression. Most of this variation acts in trans and influences biological processes related with muscle development, lipid deposition and energy balance. The identification of the underlying causal mutations and the ascertainment of their effects on phenotypes would allow gaining a fundamental perspective about how complex traits are built at the molecular level

    Bottom-up effects of plant diversity on multitrophic interactions in a biodiversity experiment

    Biodiversity is rapidly declining1, and this may negatively affect ecosystem processes, including economically important ecosystem services. Previous studies have shown that biodiversity has positive effects on organisms and processes4 across trophic levels. However, only a few studies have so far incorporated an explicit food-web perspective. In an eight-year biodiversity experiment, we studied an unprecedented range of above- and below-ground organisms and multitrophic interactions. A multitrophic data set originating from a single long-term experiment allows mechanistic insights that would not be gained from meta-analysis of different experiments. Here we show that plant diversity effects dampen with increasing trophic level and degree of omnivory. This was true both for abundance and species richness of organisms. Furthermore, we present comprehensive above-ground/below-ground biodiversity food webs. Both above ground and below ground, herbivores responded more strongly to changes in plant diversity than did carnivores or omnivores. Density and richness of carnivorous taxa was independent of vegetation structure. Below-ground responses to plant diversity were consistently weaker than above-ground responses. Responses to increasing plant diversity were generally positive, but were negative for biological invasion, pathogen infestation and hyperparasitism. Our results suggest that plant diversity has strong bottom-up effects on multitrophic interaction networks, with particularly strong effects on lower trophic levels. Effects on higher trophic levels are indirectly mediated through bottom-up trophic cascades

    Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

    Osteopathic Manipulative Treatment of Herpes Zoster Ophthalmicus/Postherpetic Neuralgia

    Herpes zoster (HZ) and herpes zoster ophthalmicus (HZO) are the result of reactivation of varicella-zoster virus (VZV) from a dormant condition. Although HZ symptoms typically subside after a few weeks, HZO and postherpetic neuralgia (PHN) can persist at least 90 days after the appearance of the HZ rash. Presently, there is no gold standard for a disease-modifying therapy for postherpetic neuralgia and the current treatment is focused on early intervention and management of symptoms and dermatological complications. In the present case, a 74-year-old Caucasian male initially developed severe right-sided eye pain and headache. He was diagnosed with HZO and treated with acyclovir, but later developed swelling over the right eye and skin rash over the right side of the forehead and face. He presented to the office after the acute manifestation of the infection disappeared, but the headache and scalp hypersensitivity persisted and increased. Osteopathic manipulative treatment (OMT) included correction of cranial strains, inhibition, myofascial release, balanced ligamentous tension, and facilitated positional release. In one week, the patient reported a reduction in pain from 10/10 to 2/10. Two weeks later, he reported complete resolution of his initial symptoms. There are a limited number of cases that illustrate the benefit of OMT in diminishing pain and associated symptoms in different types of neuralgias. OMT ensures the restoration of normal anatomical structure and associated function through correcting somatic dysfunction, normalization of blood supply, muscle tone, and lymphatic drainage, therefore, providing pain relief. Better documentation of case reports and more research in this area would greatly benefit the medical community. The present case demonstrates the successful treatment of PHN with OMT. OMT can be successfully used as an adjunct therapy in cases of HZ and PHN

    Strategies in probabilistic categorization: Results from a new way of analyzing performance

    Get PDF
    The “Weather Prediction” task is a widely used task for investigating probabilistic category learning, in which various cues are probabilistically (but not perfectly) predictive of class membership. This means that a given combination of cues sometimes belongs to one class and sometimes to another. Prior studies showed that subjects can improve their performance with training, and that there is considerable individual variation in the strategies subjects use to approach this task. Here, we discuss a recently introduced analysis of probabilistic categorization, which attempts to identify the strategy followed by a participant. Monte Carlo simulations show that the analysis can, indeed, reliably identify such a strategy if it is used, and can identify switches from one strategy to another. Analysis of data from normal young adults shows that the fitted strategy can predict subsequent responses. Moreover, learning is shown to be highly nonlinear in probabilistic categorization. Analysis of performance of patients with dense memory impairments due to hippocampal damage shows that although these patients can change strategies, they are as likely to fall back to an inferior strategy as to move to more optimal ones

    Distinct hippocampal and basal ganglia contributions to probabilistic learning and reversal

    Get PDF
    &amp; The hippocampus and the basal ganglia are thought to play fundamental and distinct roles in learning and memory, supporting two dissociable memory systems. Interesting-ly, however, the hippocampus and the basal ganglia have each, separately, been implicated as necessary for reversal learning—the ability to adaptively change a response when previously learned stimulus–outcome contingencies are re-versed. Here, we compared the contribution of the hippocam-pus and the basal ganglia to distinct aspects of learning and reversal. Amnesic subjects with selective hippocampal dam-age, Parkinson subjects with disrupted basal ganglia func-tion, and healthy controls were tested on a novel probabilistic learning and reversal paradigm. In this task, reversal can be achieved in two ways: Subjects can reverse a previously learned response, or they can select a new cue during the reversal phase, effectively ‘‘opting out’ ’ of the reversal. We found that both patient groups were intact at initial learning, but differed in their ability to reverse. Amnesic subjects failed to reverse, and continued to use the same cue and response learned before the reversal. Parkinson subjects, by contrast, opted out of the reversal by learning a new cue–outcome association. These results suggest that both the hippocampus and the basal ganglia support reversal learning, but in differ-ent ways. The basal ganglia are necessary for learning a new response when a previously learned response is no longer rewarding. The failure of the amnesic subjects to reverse their response or to learn a new cue is consistent with a more general role for the hippocampus in configural learning, and suggests it may also support the ability to respond to changes in cue–outcome contingencies. &amp
