Productivity and Composition of Fatty Acids in Chicks fed with Azadirachta indica A. Juss

ABSTRACT Objective. Evaluate the productivity and composition of fatty acids in chicks fed diets enriched with neem Azadirachta indica A. Juss seed flour. Materials and methods. 80 mixed broiler chicks of Arbor Acres stock and levels 0, 1, 3 and 5% neem seed flour added to a commercial diet were evaluated. 20 experimental units were included in each treatment for five weeks. The consumption and weight gain were recorded, as well as the composition of fatty acids in the fat by means of alkaline transesterification. Data was statistically analyzed by a completely random procedure and the measurements were compared with the Tukey test(p≤0.05). Results. The greatest weight gain, consumption and best feed conversion were found in the treatment that contains 1% neem seed flour. It also produced the increase in the proportion of polyunsaturated fatty acids, especially linoleic acid (C18:2 Omega-6) and eicosapentaenoic acid (C20:5 omega-3), and the proportion of palmitic acid (C16:0). The consumption of feed diminished when 5% of neem flour was added. Conclusions. It was demonstrated that incorporating 1% neem seed flour in the diet of broiler chicks modifies the consumption of fatty acids without harming its productive behavior. RESUMEN Objetivo. Evaluar la productividad y composición de ácidos grasos en pollos alimentados con dietas adicionadas con harina de semilla de neem Azadirachta indica A. Juss. Materiales y métodos. Se emplearon 80 pollos mixtos de la estirpe Arbor Acres de engorda y se evaluaron los niveles 0, 1, 3 y 5% de harina de semilla de neem añadidos a una dieta comercial. En cada tratamiento se tuvieron 20 unidades experimentales con una duración de cinco semanas. Se registró el consumo y la ganancia de peso, así como la composición de los ácidos grasos de la grasa mediante transesterificación alcalina. Los datos se analizaron estadísticamente por el procedimiento completamente al azar y las medias se compararon con la prueba de Tukey (p≤ 0.05). Resultados. La mayor ganancia de peso, consumo y la mejor conversión alimenticia correspondió al tratamiento que contenia 1% de harina de semilla de neem. También propició el aumento en la proporción de ácidos grasos poliinsaturados especialmente en el ácido linoleico, (C18:2 omega-6) y en el ácido eicosapentaenoico (C20:5 omega-3), y de manera concomitante se redujo la proporción del ácido palmítico (C16:0). El consumo de alimento disminuyó al adicionar 5% de harina de neem. Conclusiones. Se demostró que la incorporación de 1% de harina de semilla de neem en la dieta de los pollos de engorda modifica la composición de ácidos grasos sin perjudicar su comportamiento productivo

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

New Percutaneous Approaches for the Treatment of Heavily Calcified Mitral Valve Stenosis

Important breakthroughs have considerably improved the outcomes of the percutaneous treatment of valvular heart diseases during the last decades. However, calcium deposition and progressive calcification of the left-sided heart valves present a challenge with prognostic implications that have not been addressed until recently. In the case of native mitral stenosis with no surgical options, a compelling need for tackling heavily calcified valves has led to the development of novel debulking techniques and to the use of aortic balloon-expandable bioprosthesis in the mitral position. In this section of the special issue “Mitral Valve Disease: State of the Art”, we will review standard approaches and indications for the treatment of native mitral stenosis; summarize these two innovative solutions and their evidence, describing both procedures in a “step-by-step” fashion; and briefly comment on future directions in this field

Changes in the inner and outer retinal layers after acute increase of the intraocular pressure in adult albino Swiss mice

In adult albino mice the effects of increased intraocular pressure on the outer retina and its circuitry was investigated at intervals ranging 3–14 weeks. Ocular hypertension (OHT) was induced by cauterizing the vessels draining the anterior part of the mice eye, as recently reported (Salinas-Navarro et al., 2009a). Electroretinographic (ERG) responses were recorded simultaneously from both eyes and compared each other prior to and at different survival intervals of 2, 8 or 12 weeks after lasering. Animals were processed at 3, 9 or 14 weeks after lasering, and radial sections were obtained in the cryostat and further processed for immunocytochemistry using antibodies against recoverin, γ-transducin, Protein Kinase C-α (PKC-α), calbindin or synaptophysin. The synaptic ribbons were identified using an antibody against the protein bassoon, which labels photoreceptor ribbons and nuclei were identified using TO-PRO. Laser photocoagulation of the perilimbar and episcleral veins of the left eye resulted in an increase in mean intraocular pressure to approximately over twice its baseline by 24 h that was maintained for approximately five days reaching basal levels by 1 week. ERG recordings from the different groups of mice showed their a-, b-wave and scotopic threshold response (STR) amplitudes, when compared to their contralateral fellow eye, reduced to 62%, 52% and 23% at 12 weeks after lasering. Three weeks after lasering, immunostaining with recoverin and transducin antibodies could not document any changes in the outer nuclear layer (ONL) but both ON-rod bipolar and horizontal cells had lost their dendritic processes in the outer plexiform layer (OPL). Sprouting of horizontal and bipolar cell processes were observed into the ONL. Fourteen weeks after lasering, protein kinase-C antibodies showed morphologic changes of ON-rod bipolar cells and calbindin staining showed abnormal horizontal cells and a loss of their relationship with their presynaptic input. Moreover, at this time, quantitative studies indicate significant diminutions in the number of photoreceptor synaptic ribbons/100 μm, and in the thickness of the outer nuclear and plexiform layer, when compared to their fellow eyes. Increased intraocular pressure in Swiss mice results in permanent alterations of their full field ERG responses and in changes of the inner and outer retinal circuitries.This work was supported by research grants from the Regional Government of Murcia, Spanish Ministry of Science and Innovation and Fundaluce; FIS PIO06/0780 (MPVP); 04446/GERM/07, SAF 2009-10385; RD07/0062/0001 (MVS), FIS PI04/2399 (IP), BFU2009-07793/BFI, RD07/0062/0012, Fundaluce, ONCE (NC), RD07/0062/0008 (PdlV)

Marco conceptual para la conservación: investigación participativa, educación y comunicación en el Corredor Biológico AmistOsa

Introduction: Participatory research and environmental education initiatives exist in the AmistOsa biological corridor, Costa Rica, but an integration of these community-based processes is not yet clear. Objective: To propose and test a conceptual framework that integrates participatory research with environmental education Methods: We consulted the community to identify fauna and its threats; produced a curriculum for children; and developed a communication strategy. Results: We identified 19 vertebrate species threatened by hunting, deforestation, and others. We produced and tested an educational program adapted to the context of 14 local schools. We are currently developing communication skills to reach both children and researchers (e.g. photography workshops). Conclusion: The results of this approach are satisfactory and could be applied to other communities in the AmistOsa Biological Corridor.Introducción: Existen iniciativas de investigación participativa y educación ambiental en el corredor biológico AmistOsa, Costa Rica, pero aún no está clara la integración de estos procesos comunitarios.
