Petrology and structure of Campanario-La Haba pluton and Los Berrocales stock (Badajoz): preliminary dates
[Abstract] The Campanario-La Haba pluton and Los Berrocales stock are situated in the southern part ofthe Central-Iberian zone. They form part ofthe late-Hercynian alignement named Caceres-Linares or Pedroches-Alburquerque. During the last years these two granitoids have been related, based on spatial and/or genetic criteria, with Los Pedroches Batholith. These igneous bodies are different. Campanario-La Haba pluton is a coarse grained peraluminous granite with large megaphenocrysts ofcordierite. Three facies are differenciated based on petrographic criteria: coarse grained porfiric granite with megaphenocryst of cordierite, fine grained porfiric granite with megaphenocryst of cordierire and fine-medium granite. Los Berrocales is a zoned stock formed by granodiorites graded to granites in the center. Structure-studies indicates that the Campanario-La Haba pluton has been structurated in magmatic state. The magmatic foliation and lineation direction show the orientation ofN12üE, parallel to the pluton lenghtening. The magnetic susceptibility values show that the magnetic behaviour of the granites is dominated by paramagnetic minerals, fine for apply the Anisotropy ofthe Magnetic Susceptibility. The magnetic structure is rather homogeneous and the magnetic lineation and foliation show the N12üE direction.

The relationship between the plutonic intrusions and the dyke swarm in the Los Pedroches batholith (Iberian Massif, Spain): Dykes as a paleotectonic and paleostress indicators
[Abstract] The Los Pedroches batholith (Iberian Massif, SW Spain) is composed by a large biotite ±amphibole granodiorite pluton and several, smaller variable porphyritic, biotite ± cordierite granite intrusions. A dyke swarm composed esencially by trachyandesites, dacites and rhyolites cross cut the batholith. The whole set of plutonic and subvolcanic rocks define a K-rich, calc-alkaline alumino-cafemic association; only the trachyandesitic dykes ofshoshonitic affinity, get offthis trend. The dacitic and rhyolitic dykes are cogenetic with and probably comagmatic with thegranodioritic plutonand thegranitic intrusions, respectively. The trachyandesites, locallyshows sin-plutonic relations with thegranodiorite bodyand might becogenetic with mafic microgranular enclaves scattered through the granodiritic unit. The emplacement of the batholith and the dyke swarms is late-hercynian and postcollisional (300 Ma) and, was controled by a transtensional shear zone at acrustal scale. The dyke swarm use the tectonically generated fracture system during cooling and consolidation of the plutonic rocks: (i) R' type Riedel fractures for the trachyandesitic and dacitic dykes emplacement, and (ii) R type Riedel fractures for rhyolitic dykes emplacement. The arrangement ofsome dyke swarms can be use as a paleotectonic and paleostress indicators.
Diagnóstico y tratamiento de persistencia de cuarto arco aórtico derecho en un perro
The persistent of the aortic right arch is a congenital anomaly that is considered difficult to treat in Peru, and therefore is presented the case of a three-month-old Cocker Spaniel canine with a history of chronic regurgitation of solid foods and poor development. At clinical examination he was alert and active but with low body condition; the esophagus on palpation at the cervical level was apparently flaccid and noticeable, and at abdominal compression it seemed to increase its volume. The contrasted radiographic image revealed a marked esophageal distension located in front of the cardiac image, which gave the diagnosis of a pre-cardiac megaesophagus. The presumptive diagnosis was the presence of the fourth persistent right aortic arch, so the surgery was suggested to the owners. Exploratory thoracic surgery was performed confirming the diagnosis and corrective surgery was performed by ligand and transecting the fourth persistent aortic arch. A rapid recovery was observed in the patient, and monthly evaluations for a year were done without detecting complications.El cuarto arco aórtico persistente es una anomalía congénita que se considera de difícil tratamiento en el Perú, por lo que se presenta el caso de un canino Cocker Spaniel, de tres meses de edad, con historia de regurgitación crónica de alimentos sólidos y bajo desarrollo. Al examen clínico se mostraba alerta y activo con condición corporal baja; el esófago a la palpación a nivel cervical se mostraba aparentemente flácido y notorio y a la compresión abdominal parecía distenderse. La imagen radiográfica contrastada reveló una notoria distención esofágica localizada delante de la imagen cardiaca, lo que dio el diagnóstico de un megaesófago pre-cardiaco. El diagnostico presuntivo fue la presencia del cuarto arco aórtico persistente, por lo que se sugirió a los propietarios la realización de la cirugía. Se realizó la cirugía exploratoria torácica confirmando el diagnóstico y se realizó la cirugía correctiva ligando y transectando el cuarto arco aórtico persistente. Se observó una rápida recuperación en el paciente, habiéndolo evaluado mensualmente durante un año sin presentar complicaciones
Omentalization for the treatment of prostatic abscesses in dogs: two clinical cases
Se presentan los resultados de dos casos de omentalización prostática realizada en dos pacientes caninos que fueron diagnosticados con cuadros de abscedación prostática. La edad de los pacientes fue de 9 y 13 años. Presentaron fiebre, polaquiuria, decaimiento, anorexia y dolor abdominal. Las ecografías mostraron presencia de quistes/abscesos en la glándula prostática. La técnica quirúrgica se desarrolló de manera sencilla sin la necesidad de utilizar equipamiento complejo fuera del material quirúrgico básico. Los pacientes se recuperaron rápidamente del procedimiento quirúrgico sin observarse complicaciones pos-quirúrgicas. Se concluye que la técnica de omentalización prostática permite el tratamiento efectivo de abscesos intraprostáticos en perros.This paper presents the results of two cases of prostatic omentalization conducted in two canine patients who were diagnosed with prostatic abscess. The patients were 9 and 13 years old. They presented fever, frequent urination, decay, anorexia, and abdominal pain. The ultrasound showed presence of cysts/abscesses in the prostate gland. The surgical technique was developed in a simple manner without the need of using complex equipment outside the basic surgical material. Patients recovered quickly from the surgical procedure without having post-surgery complications. It is concluded that the technique of prostatic omentalization allows the effective treatment of intra-prostatic abscesses in dogs

Análisis retrospectivo de agentes bacterianos y patrones de susceptibilidad antibiótica en casos de infecciones del tracto urinario en caninos domésticos (2012-2017)
The present study aimed to describe and analyse the results of bacterial isolates and their antibiograms in canine patients with a diagnosis of urinary tract infection, which were treated at the Small Animal Clinic of the Faculty of Veterinary Medicine of Universidad de San Marcos between 2012 and 2017. In total, 97 medical records of patients who had urine cultures and antibiograms exams were identified. The bacterial agents isolated were Escherichia coli (36.9%), Staphylococcus sp (28.7%), Proteus sp (27.9%), Pseudomonas sp (3.3%), Klebsiella sp (1.6%), Streptococcus sp (0.8%) and Citrobacter sp (0.8%) These evidenced a high antibiotic resistance due possibly to the inappropriate use of antibiotics in the country, so it is not possible to recommend a safe initial treatment in canine patients with presumptive diagnosis of this disease.El presente estudio tuvo como objetivo describir y analizar los resultados de los aislados bacterianos y sus antibiogramas en pacientes caninos con diagnóstico de infección del tracto urinario, que fueron atendidos en la Clínica de Animales Menores de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos entre 2012 y 2017. Se identificaron 97 historias clínicas de pacientes que contaban con exámenes de urocultivos y antibiogramas. Los agentes bacterianos aislados fueron Escherichia coli (36.9%), Staphylococcus sp (28.7%), Proteus sp (27.9%), Pseudomonas sp (3.3%), Klebsiella sp (1.6%), Streptococcus sp (0.8%) y Citrobacter sp (0.8%). Estos evidenciaron una alta resistencia antibiótica debido posiblemente al uso inadecuado de los antibióticos en el medio, por lo que no permite recomendar un tratamiento inicial seguro en pacientes caninos con diagnóstico presuntivo de esta enfermedad
Modelización de un sistema territorial "urbano-rural" para la evaluación de su sostenibilidad. Aplicación a una zona representativa del País Vasco
El desarrollo de una base de conocimiento común y sólida que permita la máxima objetividad y transparencia en la evaluación de la sostenibilidad dentro del proceso de toma de decisiones, constituye uno de los pilares básicos para su implementación en el planeamiento estratégico y la gestión del territorio. La caracterización del sistema ecológico-ambiental, económico, social e
institucional que es objeto de gestión constituye un paso clave en el conocimiento de la red de relaciones que subyace al funcionamiento del sistema y de las interacciones responsables de potenciales sinergias. La traducción de esta información en modelos conceptuales y matemáticos
constituye una herramienta útil en el desarrollo de indicadores de sostenibilidad eficaces y relevantes, enfocados desde las necesidades de gestión. En este trabajo se presenta el modelo conceptual que define los componentes e interacciones de un sistema urbano-rural representativo del País Vasco, así como su marco de evaluación.One of the most important factors in introducing the concept of sustainability into strategic planning and territorial management is the development of a shared, solid knowledge base. This knowledge base should ensure maximum objectivity and transparency in sustainability assessment within the decision-making process. A description of the ecological-environmental, economic, social and institutional system that is to be managed is needed in order to develop knowledge about the network of relations that underlie the functioning of the system and the interactions that are responsible for potential synergies. The transformation of this information into conceptual and mathematical models is a useful tool for developing effective and relevant sustainability indicators that are oriented towards management needs. This paper presents a conceptual model that defines the components and interactions of a representative urban-rural system in the Basque Country. It also discusses the assessment frame for this model
Methane production in grazing cattle supplemented with silage, concentrate and tannins in the Peruvian highlands during the dry season
El objetivo del estudio fue determinar la producción de metano en vacunos al pastoreo en el altiplano peruano en un pastizal de Festuca dolichophylla - Muhlenbergia fastigiata (Chilliguar), suplementados con ensilado y concentrado o taninos durante la época seca (agosto). El estudio se realizó en el Centro Experimental «La Raya», Cusco, Perú, ubicado a una altitud de 4200 msnm. Se plantearon tres tratamientos (T1: pastos naturales + ensilado de avena; T2: como en T1 + taninos; T3: como en T1 + concentrado). Cada tratamiento contenía cuatro repeticiones distribuidos en un diseño jerárquico. La determinación de metano se realizó con la técnica del marcador con hexafluoruro de azufre (SF6), siendo la frecuencia de medición por animal de 24 h por 7 d. El contenido de energía promedio en el pastizal fue de 4.1 Mcal EB/g, materia orgánica 91.8%, proteína cruda 10.3% y materia seca 91.1%. La producción de metano (g/d) para T1 fue de 421.7 ± 43.4, para T2 de 330.6 ± 66.7 y para T3 de 367.7 ± 116.5. La utilización de taninos redujo significativamente (p<0.05) las emisiones de metano frente al uso o no de concentrado.The aim of the study was to determine the methane production in cattle grazing in the Peruvian highlands in a pasture of Festuca dolichophylla - Muhlenbergia fastigiata (Chilliguar), supplemented with silage and concentrate or tannins during the dry season (August). The study was conducted at the Experimental Centre «La Raya», Cusco, Peru, located at an altitude of 4200 m. Three treatments were used (T1: natural grass + oat silage, T2: as in T1 + tannins, T3: as in T1 + concentrate). Each treatment had four replicates distributed in a hierarchical design. Methane determination was performed using the sulfur hexafluoride (SF6) marker technique. The measurement was during 24 h for 7 d. The average energy content in the pasture was 4.1 Mcal GE/g, organic matter 91.8%, crude protein 10.3% and dry matter 91.17%. The methane (g/d) production for T1 was 421.7 ± 43.4, for T2 was 330.6 ± 66.7 and for T3 was 367.7 ± 116.5. The use of tannins significantly reduced (p<0.05) methane emissions from only silage supplementation or silage plus concentrate
Formative research in critical epidemiology of infectious diseases in Latin America 2010 to 2020
Epidemiology has been an essential interpretative tool to understand the collective health of society, especially in the case of infectious diseases, but its diagnostic role in public health is permanently subjected to diametrically opposed reasoning, epidemiological practices, and social demands. It provides the equipment to evaluate the quality of life of the population and its success depends on its economic and political providers, paradigms and applied research models, many of them merely the result of the free will and autonomous decisions of its specialists, academics or not academics. The purpose of this research was to describe the current situation of Latin American scientific production in the period 2010 to 2020 in relation to formative research on epidemiology. The bibliometric study is based on the descriptive-retrospective analysis of contributions collected in Scopus indexed journals. In this sense, a total of 120 publications were collected, with Colombia being the country that contributes the highest scientific production, amounting to 23.33%, followed by Mexico and Peru with values of 18.33% and 17.50%, respectively. Likewise, there are 83 international institutions that have participated in the production of the topic in question, highlighting the institutions of Mexico, Peru and Colombia, with four or more published articles. In short, as a region, a progressive growth is perceived in terms of scientific production, a favorable situation to use formative research as a transversal and integral strategy in contribution to the development of the research component, the latter being a transcendental and mandatory function in universities. of our country
