Fat is the major fuel for migratory flight of birds, but protein is also catabolized. Flight range could be reduced if protein is used too quickly from muscles and organs, and it is important to understand factors that influence protein catabolism. Previous correlative studies suggested high protein diets may increase protein use in flight, although a wind tunnel study with yellow-rumped warblers (Setophaga coronata) did not support this relationship. We tested the hypothesis that diet composition affects nutrient oxidation in resting, fasted yellow-rumped warblers. For method development, we gavaged or subcutaneously injected warblers with 13C labelled glucose or leucine, and measured δ13C of breath CO2 in real time using infrared laser spectrometry. Regardless of route of administration, leucine had greater instantaneous and cumulative oxidation than glucose. Compared to subcutaneous injection, gavaged birds reached maximum oxidation rate faster for leucine and glucose, respectively, had a higher maximum oxidation rate, and reached final cumulative oxidation approximately faster for leucine or glucose, respectively, indicating immediate oxidation of the substrates by the digestive system. Warblers (N = 10 each) were fed isocaloric 60% carbohydrate or 60% protein diets for minimum 2 weeks, and subcutaneously injected with 13C labelled glucose or leucine. Diet composition had little effect on oxidation kinetics except that warblers fed high-carbohydrate reached final cumulative oxidation of leucine more quickly than those fed high-protein. The findings do not support the hypothesis that high protein diets increase the oxidation of protein during negative energy states in migratory birds, and provide methodology that could be applied to test it in flight.The role of photocoagulation in retinal vein occlusion (RVO) has been studied since 1974. The most serious complications of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) are (i) visual deterioration, most commonly due to macular edema, and (ii) the development of ocular neovascularization (NV), particularly neovascular glaucoma (NVG), with hazardous consequences for vision and even the eye itself. Before discussing the role of photocoagulation in the management of NV and macular edema in RVO, it is crucial to gain a basic scientific understanding of the following relevant issues classification of RVO, ocular NV in RVO, and the natural history of macular edema and visual outcome of RVO. These topics are discussed. In CRVO, ocular NV is a complication of ischemic CRVO but not of nonischemic CRVO. Photocoagulation has been advocated to prevent and/or treat the development of ocular NV and NVG. Since NVG is the most dreaded, intractable and blinding complication of ischemic CRVO, the role of photocoagulation and its management are discussed. Findings of three randomized, prospective clinical trials dealing with photocoagulation in ischemic CRVO are discussed. The role of photocoagulation in the management of ocular NV and macular edema in BRVO, and three randomized, prospective clinical trials dealing with those are discussed. Recent advent of intravitreal anti-VEGF and corticosteroid therapies has drastically changed the role of photocoagulation in the management of macular edema and NV in CRVO and BRVO. This is discussed in detail.The allelic combination of ROP18/ROP5 genes of Toxoplasma gondii has been shown to be highly predictive of mouse virulence in canonical isolates and strains. The aims of this study were to analyze the alleles present in the ROP18/ROP5 genes from T. gondii isolates obtained in Argentina, to associate the results with the virulence registered in mouse model, and to compare with other isolates and reference strains using a phylogenetic network. Fourteen T. gondii isolates from Argentina were analyzed by nPCR-RFLP for ROP18/ROP5. Phylogenetic network analysis was inferred using the ToxoDB genotypes and the ROPs molecular markers. All isolates and reference strains were categorized as lethal or non-lethal. As results, combinations 2/2, 3/3 and 4/3 for ROP18/ROP5 were detected in 12 isolates, whereas only alleles 1 and 2 of ROP5 were detected in 2 isolates. The majority of the isolates had a mouse virulence matching to that predicted by the ROP18/ROP5 allele combination. The 3 isolates that differed from the expected virulence presented non-clonal genotypes. ROPs incorporation increased the accuracy of the phylogenetic network relations among the T. gondii samples, prevailing the clustering according to regions. Our results indicate a predominance of type 3 allele in both ROP18 and ROP5 markers and an association of allelic profiles 3/3 and 4/3 of non-clonal genotypes from Argentina, both with virulent and avirulent profiles in mice.Obesity is a global burden and a chronic ailment with damaging overall health effects. Ghrelin, an octanoylated 28 amino acid peptide hormone, is secreted from the oxyntic mucosa of the stomach. Ghrelin acts on regions of the hypothalamus to regulate feeding behavior and glucose homeostasis through its G protein-coupled receptor. Recently, several central pathways modulating the metabolic actions of ghrelin have been reported. While these signaling pathways can be inhibited or activated by antagonists or agonists, they can also be discriminatingly activated in a "biased" response to impart different degrees of activation in distinct pathways downstream of the receptor. Here, we review recent ghrelin biased signaling findings as well as characteristics of ghrelin hormone and its receptors pertinent for biased signaling. click here We then evaluate the feasibility for ghrelin receptor biased signaling as a strategy for the development of effective pharmacotherapy in obesity treatment.Applied epidemiologists are key professionals within the public health workforce, fulfilling core public health science functions. The public health system in the United States has been rapidly transforming over the last decade and epidemiologists will need to develop new skill sets to be successful in the future of public health. A review of the literature was undertaken to gain a comprehensive understanding of the past and present of the applied epidemiology workforce to inform future workforce initiatives aimed at improving applied epidemiology practice. The literature search identified 48 articles related to applied epidemiologists working in the United States at the federal, state, and local levels. These articles described efforts to build, enumerate, and assess the competency of the applied epidemiology workforce in addition to putting forward opinions about it. Overall, the articles demonstrated significant prior work enumerating the applied epidemiology workforce, some prior work identifying epidemiology training needs, and few prior studies assessing competency.
