Santa Inês

 The objective of this study was to evaluate the effect of different hormonal protocols on the reproductive performance of Santa Inês ewes in Amazon environmental conditions. Twenty-two Santa Inês ewes between 3 and 4 years-old were distributed in a randomized block experimental design, where the treatments consisted of two protocols for estrus synchronization (short and long) with eleven animals each. Data on the occurrence of estrus were described for each protocol. Data of estrus, pregnancy, and prolificity were firstly subjected to ANOVA and a subsequent Tukey’s test. Results were considered significant at p ≤ 0.05. The short-term protocol presented an interesting successful rate, where above 70% ewes tested had estrus. The long-term protocol also achieved a high successful rate, where above 80% ewes tested had estrus. However, comparing the protocols, the long-term protocol presented better results of positive estrus and pregnancy rates in ewes. Thus, it can be concluded that both protocols presented satisfactory results regarding estrus manifestation, and prolificity (lambs produced per ewe). However, under Amazon environmental conditions, the long-term protocol presented better results regarding positive manifestation of estrus and pregnancy rate.

Objectives. To study the short-term effect of eye opening and use of topical dexamethasone phosphate 0.1% and levofloxacin 0.5% on the cytokine levels in human tears.Methods. Prospective experimental design was used for tear collection from eyes of 10 healthy controls and 20 patients four days after penetrating keratoplasty (PKP) at awakening and after instilling dexamethasone or levofloxacin. The concentrations of different cytokines were measured by cytometric bead array.Results. At eye opening, IL-6 levels were higher in the PKP group as compared to the controls. Thirty minutes later, the released levels of IL-10, IL-13, IL-17, IFNγ, and CCL5 increased in controls, while CXCL8 decreased in both control and PKP groups. The release of the cytokines remained stable after 30 mins except for IFNγ, which showed a decrease in the controls following levofloxacin instillation. No short-term effects of the topically used dexamethasone and levofloxacin could be detected on the cytokine levels in controls and after PKP.Conclusions. Evidence of changes in the levels and time course of tear cytokines after awakening or eye opening could be established and the short-term confounding effects of dexamethasone and levofloxacin on the levels of released cytokines in human tears could be excluded.

Short And Long Term

This study investigates whether the influence of financial expertise on stock investors’ ability to predict risk and return is contingent on the length of the forecast horizon. In a quasi-experimental design, stock market professionals (N1=63, N2=36), private shareholders (N1=155, N2=172) and students (N1=124, N2=90) twice provided their short- (3-month) and long-term (2-year) risk and return predictions on stock indices. The results show that in general, experts did not outperform students or private shareholders in their return predictions. However, the level of financial expertise positively influenced the accuracy of risk predictions. An interaction effect between financial expertise and the length of the forecast horizon suggests that more knowledgeable and experienced investors performed better in the long term compared to the short term than inexperienced investors did

Background and Hypothesis: Global health has made strides in controlling and reducing harm from infectious diseases such as Polio and HIV/AIDS but this focus has not been mirrored in surgical and anesthesia care, especially in many low and middle-income countries (LMICs). In 2010, an estimated 16.9 million lives were lost from conditions that required surgical care and 5 billion people in LMICs lack safe and affordable surgical and anesthesia. Organization of surgical camps can bring skilled physicians to temporarily meet the unmet surgical needs in underserved areas. However, currently there are no government agencies or accrediting bodies existing to assess the scope/impact of short-term surgical camp care or establish standards of care for such services.   Experimental Design or Project Methods: The AMPATH mission of “start with healthcare and then do more to empower communities, educate tomorrow’s medical experts and research breakthroughs that will truly change the health of the world” was incorporated into the ethical checklist proposed. The four principles – beneficence, non-maleficence, autonomy, and justice were used as guidance for the checklist.   Results: The checklist can be organized into three main areas: Care, Empowerment & Training, and Research (Figure 1).
