Productividad y eficiencia de uso de nitrógeno y energía en pollos de engorda alimentados con pasta de soya o pasta de canola

Two slaughter experiments were carried out to evaluate the growth, content and deposition of tissues and the protein and energy retention in the meat of the carcass in growing broiler fed with canola meal (CANM) in substitution of soybean meal (SOYM). In Exp 1, six male broilers, 43 d of age, were slaughtered at the beginning and 36 broilers were assigned to three diets with increasing amounts of CANM (0, 10 and 20 %) combined with two levels of digestible lysine (DL: 0.85 y 0.95 %). In Exp 2, six female and six male broilers, 28 d of age, were slaughtered at the beginning and 72 broilers were assigned, within sex, to two diets (SOYM or CANM as unique protein source) combined with three energy levels (3.0, 3.1 and 3.2 Mcal of ME/kg of feed). Each experiment lasted two weeks and at the end all birds were sacrificed. In Exp 1, there were not statistical differences in the productivity or the protein and energy retention in the carcass among CANM levels (P>0.05). In Exp 2, the feed, protein and energy intake and the fat deposition were greater (PSe realizaron dos experimentos de sacrificio para evaluar el crecimiento, contenido y deposición de tejidos y retención de proteína y energía en la carne de la canal en pollos en crecimiento alimentados con pasta de canola (PCAN) en sustitución de pasta de soya (PSOY).

Co-deposited Ni-Cr-B Nanocomposite Coatings for Protection Against Corrosion-Erosion

Electrodeposition is a low-cost and low-temperature method for producing metal matrix composite coatings. The electrodeposition of Ni matrix/Ni-Cr-B particles is considered as the co-deposition of Ni-Cr-B particles in a Ni matrix, resulting in nanocomposite coatings that can offer good wear and corrosion resistance between other applications. For comparison, the electrodeposition of Ni films and their wear and corrosion evaluation were also carried out under the same conditions. Some coatings usually contain oxide or carbide particles in micrometer size and are electrodeposited in a nickel matrix; however, the use of the mechanical alloying process offers the possibility to reduce the particle size in the order of nanometers obtaining solid solutions, amorphous phases, or intermetallic compounds during the development of new alloys to be co-deposited, improving the engineering materials properties. This kind of nanocomposite can be used in industrial components with an irregular geometry exposed in aggressive environments such as the energy generation and oil industry

Supercritical Impregnation of PLA Filaments with Mango Leaf Extract to Manufacture Functionalized Biomedical Devices by 3D Printing

Polylactic Acid (PLA) filaments impregnated with ethanolic mango leaves extract (MLE) with pharmacological properties were obtained by supercritical impregnation. The effects of pressure, temperature and amount of extract on the response variables, i.e., swelling, extract loading and bioactivity of the PLA filaments, were determined. The analysis of the filaments biocapacities revealed that impregnated PLA filaments showed 11.07% antidenaturant capacity and 88.13% antioxidant activity, which after a 9-day incubation shifted to 30.10% and 9.90%, respectively. Subsequently, the same tests were conducted on printed samples. Before their incubation, the printed samples showed 79.09% antioxidant activity and no antidenaturant capacity was detected. However, after their incubation, the antioxidant activity went down to only 2.50%, while the antidenaturant capacity raised up to 23.50%. The persistence of the bioactive properties after printing opens the possibility of using the functionalized PLA filaments as the feed for a three-dimensional (3D) printer.This work is part of a project granted by the Junta de Andalucia (P18-RT-3272) through its financing by the FEDER funds 2014-2020

Characterization of Patients with Acute Myocardial Infarction Treated at the General University Hospital Dr. Gustavo Aldereguía Lima

Background: ST-segment elevation acute myocardial infarction poses a great challenge to health systems, therefore its diagnosis and management are important. Objective: to determine the main clinical-epidemiological characteristics of patients diagnosed with ST-segment elevation acute myocardial infarction. Methods: a descriptive and cross-sectional study was carried out on a series of patients treated at the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos, from January to June 2021. The universe consisted of 77 patients. Variables such as: age, sex, skin color, origin, comorbidities, toxic habits, clinical manifestations, thrombolysis, place where they were thrombolyzed, causes of non-thrombolysis, topography of acute myocardial infarction, discharge status, infarction complications and of thrombolytic treatment. For the processing and analysis of the information, a database was created in the statistical package SPSS version 21.0 that allowed the calculation of the absolute frequencies and the percentages. Results: the mean age was 66.08 (±9.43). There was a predominance of the male sex (64.7 %); 59.7 % of the patients were thrombolyzed; typical chest pain was the main clinical manifestation with 71.4 %; 12 patients died, of which 10.4 % did not receive thrombolytic treatment. Conclusions: the main reason for consultation continues to be chest pain. Age and comorbidities are risk factors to take into account when preventing this entity. Thrombolysis is a therapeutic measure that has a direct impact on the state at discharge of patients, this procedure is performed mostly in the hospital

Proposta educativa para a saúde do paciente com diabete mellitus tipo 2

Health psychology focuses on the study of the psychological processes involved in health and illness, and incorporates a wide range of activities: health promotion, illness prevention, and attention for both the sick and for people suffering the aftereffects of illness. It also plays a role in the provision of health services according to the needs of the recipients. Given the worldwide prevalence of diabetes mellitus type 2, the conditions and quality of life of people with this disease has become a public health issue that must be addressed seriously. Although the treatment of diabetes is the direct responsibility of professionals and institutions working in this area, a multidisciplinary effort would help greatly in finding a solution or improving the condition, and psychology, as a generator of knowledge that could be applied, therefore has a place in this wider working team. The objective of this research study was to design an educational proposal based on the psychological model of biological health (Ribes, 1990) to promote preventative behavior in patients with diabetes mellitus type 2.La psicología de la salud se aboca al estudio de aquellos procesos psicológicos que participan en el proceso salud-enfermedad. Comprende un plano amplio de actividades: promoción de la salud, prevención de enfermedades, atención tanto de enfermos como de personas con diversas secuelas de enfermedades y de igual manera interviene en la adecuación de los servicios de salud a las necesidades de los que los reciben. Dada la prevalencia de personas con diabetes mellitus tipo 2 en el mundo, las afecciones y la calidad de vida de quien padece esta enfermedad se han convertido en un problema de salud pública que debe ser atendido con seriedad. Si bien es cierto que la atención de la diabetes le atañe a los profesionales y a las instituciones encargados de esa dimensión, sumar esfuerzos en un nivel multidisciplinario debe favorecer en gran medida la solución o mejora de esa condición, por lo que la psicología, como generadora de conocimiento susceptible de ser aplicado, se agrega desde su dimensión al equipo de trabajo. El objetivo de esta investigación fue diseñar una propuesta educativa fundamentada en el modelo psicológico de la salud biológica (Ribes, 1990) para promover conductas de prevención en pacientes con diabetes mellitus tipo 2.A psicologia da saúde se dedica ao estudo daqueles processos psicológicos que participam do processo saúde-doença. Compreende um plano amplo de atividades: promoção da saúde, prevenção de doenças, atendimento tanto de doentes quanto de pessoas com diversas sequelas de doenças, além de intervir na adequação dos serviços de saúde às necessidades dos que os recebem. Tendo em vista a prevalência de pessoas com diabete mellitus tipo 2 no mundo, as afecções e a qualidade de vida de quem padece dessa doença se converteram num problema de saúde pública que deve ser atendido com seriedade. Embora seja certo que o atendimento da diabete corresponda aos profissionais e às instituições encarregadas dessa dimensão, somar esforços num nível multidisciplinar deve favorecer, em grande medida, a solução ou melhora dessa condição; razão pela qual a psicologia, como geradora de conhecimento suscetível de ser aplicado, se soma, sob sua dimensão, à equipe de trabalho. O objetivo desta pesquisa foi desenhar uma proposta educativa fundamentada no modelo psicológico da saúde biológica (Ribes, 1990) para promover condutas de prevenção em pacientes com diabete mellitus tipo 2
