El sector productivo de carne vacuna crece y las características en el consumo cambian. Los aspectos que se tienen en cuenta al momento de comprar son variados, como también las condiciones y manejos en los locales de venta. Conocer características y observaciones en carniceros barriales, intermediarios entre el frigorífico y el consumidor, permitirá conocer este eslabón clave en la venta de carne vacuna en Argentina. El presente trabajo planteó como objetivo estudiar aspectos vinculados a la producción, manejo, valoración, consumo y atributos de calidad de la carne vacuna mediante encuesta a carniceros barriales. Sesenta carniceros, considerando todas las zonas de la ciudad de Tandil, fueron entrevistados personalmente. El análisis de conglomerados permitió observar dos agrupamientos: CON-1(3-zonas) y CON-2(4-zonas). Mayoritariamente no se hallaron diferencias entre los vendedores en los aspectos de producción y manejo. Una diferencia significativa fue observada en la frecuencia de compra de las medias reses. Asimismo, todos indicaron poseer cámara fría, pero rechazaron posibles atributos de maduración. En relación con el consumo y atributos de calidad, se destacó el color como factor ?frescura? y preferencia de sus productos por higiene-sanidad, calidad y confianza. La presencia de la grasa intramuscular mostró diferencias significativas; en CON-1, el 80 % de sus clientes prefiere cortes con marmoleo, mientras que en CON-2, el 96 % elige cortes magros. Todos manifestaron observar cambios en los hábitos y volumen de compra en los últimos años. A la luz de los resultados, será necesario continuar con el trabajo de investigación interdisciplinar, para comprender y lograr mejoras considerando los aspectos socioeconómicos y tecnológicos de la calidad de la carne vacuna. The productive beef sector grows, and consumption traits change. The aspects considered at the time of purchase varied, as well as the conditions and handling in the sale points. Knowing the features and observations of neighborhood butchers, intermediaries between the cold storage and the consumer, will allow knowing this critical link in the beef sale in Argentina. The aim of this work was to study aspects related to the production, handling, assessment, consumption, and quality attributes of beef through a survey of local butchers. Sixty butchers, considering all areas of the city of Tandil, were personally interviewed. The cluster analysis allowed observing two groupings: CON-1(3-zones) and CON-2(4-zones). Mainly, no differences were found between sellers in production and management aspects. A significant difference was observed in the purchase frequency of half cattle carcasses. Likewise, all indicated having a cooling room, but rejected possible beef-maturation attributes. In relation to consumption and quality attributes, the color was highlighted as a "freshness" factor and preference of their products considering hygiene-sanitation, quality, and trust. The presence of intramuscular fat showed significant differences; in CON-1, 80 % of their clients prefercuts with marbling, while in CON-2, 96 % choose lean cuts. All stated observing changes in purchasing habits and volume in recent years. In light of the results, it will be necessary to continue with interdisciplinary research work, to understand and achieve improvements considering the socio-economic and technological beef quality aspects.

Campylobacter fetus is a gram-negative, motile, spiral or S-shaped bacterium, which induces campylobacteriosis. This disease causes decrease productivity of cattle. Although considerable research has been done on the role of C. fetus on female fertility, little is known about the effect on bulls. The aim of this work was to evaluate the effect of C. fetus subsp. fetus (Cff) and C. fetus subsp. venerealis (Cfv) on bull sperm quality. Samples of frozen semen (n = 29 straws) were each distributed into three groups: two of them incubated with the microorganism (Cff, Cfv) and a control group. The proportions of live spermatozoa, with functional membrane and true acrosomal reaction in control group were significantly (P < 0.01) greater than those observed in Cff and Cfv groups. However, no significant differences (P > 0.05) were found in sperm chromatin structure among treatments. In adhesion assay, proportions of spermatozoa with adhered Campylobacter were similar for both subspecies. Results confirm that Cff and Cfv have the same ability to bind in an irreversible way to bull spermatozoa and to affect sperm quality. It is proposed that adherence could be considered as the main cause of sperm alterations, and also an important step of pathogenesis and venereal transmission. Fil: Cagnoli, Claudia Ines.

Laser scanning and 3D point cloud data is used extensively in open pit and underground mining operations. Point cloud data generated with laser scanners has improved survey, conformance, and geotechnical process efficiency and has become a key data component for planning, operations and decision-making. The advent of new software tools designed specifically to manage real-time 3D scan data has also improved the accuracy, quality and usability of underground scan data, revolutionising workflows through the industry. In this paper, several case studies will demonstrate the versatility and value of laser scanning in the context of underground operations demonstrating the use of laser scanning and derived point cloud data to improve efficiency, reduce costs and increase the safety of staff and assets across the operation.

Objectives: The aim of this study was the comparison of a new double-coated paclitaxeleluting coronary stent with bare-metal stent (BMS) in patients undergoing percutaneous coronary intervention. Background: Stent coating with biodegradable polymers as a platform for elution of drugs has the potential for complete elution of drugs and for decreasing the risk of late complications. Methods: Multicenter randomized trial comparing a paclitaxel-eluting stent (PES) coated with a biodegradable polymer and glycocalyx with the equivalent BMS. We randomly assigned 422 patients with de novo coronary lesions to PES (211 patients) or to BMS (211 patients). Primary end point was target vessel failure (TVF) defined as cardiac death, myocardial infarction, and target vessel revascularization. Clinical secondary end points were target vessel revascularization, target lesion revascularization, stent thrombosis (ST), and major adverse cardiovascular events (MACE). Angiographic secondary end points were late loss and binary restenosis. Results: At 1 year of follow-up, TVF rate was 9.5% in the PES group and 17.1% in the BMS group (P 5 0.02), and MACE rate was 10% in PES and 19% in BMS arm (P 5 0.009). All other secondary end points were reached but ST. ST rate was low and similar in both study arms. Conclusions: The study shows that patients treated with PES with dual coating technology had significantly lower incidence of TVF and MACE than those treated with BMS design; however, longer follow-up should be necessary to assess true advantages of this technology compared with the previous one.

Modern embedded systems may consist of many devices, which may have complex interconnections between them. Many of these devices may also need to be configured and programmed during development and production. The JTAG port and boundary scan techniques are the industry standard for that task, but are not supported by all devices. This paper presents the use of an FPGA as the means of interconnection between all devices and to provide a single configuration interface for the system. The flexible interconnections in the FPGA allow for faster development times and flexible and reconfigurable interconnections. The FPGA also provides a single, standard JTAG interface to the user during development and production The FPGA acts as a bridge between the standard programming interface and proprietary programming protocols and interfaces, easing development and simplifying the programming task during production and on the field.

Our purpose was to assess noninvasive imaging in detection of subclinical atherosclerosis and to examine novel invasive modalities to describe prevalence and temporal changes in putative characteristics of "high-risk" plaques.Conventional coronary imaging cannot identify "high-risk" lesions.Conventional (quantitative angiography and intravascular ultrasound [IVUS]) and novel imaging (IVUS-based palpography and gray scale echogenicity) were performed at baseline and 6 months later in 67 patients with diverse clinical presentations. Different imaging techniques were compared within a common segment defined by multislice computed tomography (MSCT).Compared with IVUS, the sensitivity, specificity, and positive and negative predictive value of MSCT for detecting significant plaque was 86%, 69%, 90%, and 61%, respectively. In coronary arteries with50% stenosis, there were no temporal changes in luminal and plaque dimensions measured by quantitative coronary angiography or IVUS; however, a significant reduction in abnormal strain pattern was detected on palpography (density high strain spots/cm: 1.6 +/- 1.5 vs. 1.2 +/- 1.4, p = 0.0123. These changes were mainly related to significant changes in patients who presented with ST-segment elevation myocardial infarction. The assessment of plaque echogenicity showed no temporal changes. There were no correlations between circulating biomarkers and quantifiable imaging parameters.Mild angiographic disease is associated with large atherosclerotic plaques on MSCT. Conventional invasive coronary imaging reveals static luminal and plaque dimensions on standard medical therapy with plaque hypoechogenicity remaining unchanged over the 6-month period. By contrast, palpography measurements of strain correlate with clinical presentation and significantly decrease on standard medical therapy. Novel imaging modalities, such as palpography, might provide insights into plaque biology and might eventually serve as intermediate end points in interventional trials.

The psychometric characteristics of the Weekly Stress Inventory (WSI) were examined in a sample of medical patients (N = 84) diagnosed with coronary heart disease. In addition to the WSI, patients completed measures assessing recent depressive symptoms, physical symptoms, Type A behavior, and trait anxiety. Patients also monitored stress for 3 weeks (n = 46), completing the Daily Stress Inventory (a measure of minor stress) daily and the WSI at concurrent 1-week intervals. Results indicated that the WSI is an internally consistent and moderately stable measure. Validity of the WSI was supported by (a) strong correlations with a concurrently administered measure of minor stress (concurrent validity); (b) significant positive correlations with measures assessing recent depressive symptoms, physical symptoms, and Type A behavior; and (c) a lack of relationship with a measure of trait anxiety (discriminant validity).

This study was designed to evaluate the efficacy of a brief, structured pain management program to improve control over chest pain episodes in patients diagnosed with coronary artery disease. Twenty-six male veterans who attended the three-session program were compared with twenty-six matched controls. Results indicated significant short-term reductions in self-report of number of chest pain episodes in treated subjects. Self-report of pretreatment daily physical activity level moderated treatment outcome, as individuals reporting lower levels of physical activity derived greater benefit than their high-activity counterparts. These results suggest the potential utility of incorporating chest pain control strategies into comprehensive cardiac rehabilitation programs.
