Terapéutica racional, mediante indicadores de eficacia antimicrobiana, de la mastitis caprina utilizando marbofloxacina y cefquinoma. Rational therapeutics, indicators of antimicrobial efficiency in the mastitis goats using marbofloxacine and cefquinome

La producción de leche de cabra es considerada en nuestro país, y en la provincia de Córdoba, una alternativa productiva para el desarrollo sustentable y socio – económico de la población. Por otra parte, existe una mayor demanda del mercado nacional e internacional de esta leche, por lo que los productores deben garantizar la seguridad y calidad de la misma de acuerdo a las normas vigentes. Es por ello que el control y tratamiento de las diferentes enfermedades es de vital importancia tanto para maximizar la producción del hato como para cumplir con los cánones de seguridad exigidos. En este contexto la mastitis caprina es una de las enfermedades que afecta la productividad del sector, y para controlarla una de las medidas a emplear es la terapéutica con antimicrobianos. Se trabajará en este proyecto con marbofloxacina y cefquinoma, estableciendo pautas racionales (eficaces y seguras) para su empleo en la afección a nivel regional. Los indicadores de eficacia estarán fijados de acuerdo a los parámetros integrados de farmacocinética (FC) y farmacodinamia (FD). Estos últimos (FD) serán calculados a través de la determinación concentraciones inhibitorias mínimas de cepas bacterianas aisladas de mastitis caprinas en Córdoba. Se establecerán los parámetros farmacocinéticos a dosis únicas y múltiples para la marbofloxacina (5 mg/kg IV, IM) y cefquinoma (2 mg/kg IV, IM e IMM) a partir de muestras de suero y leche de cabras Anglo Nubian (n = 6 por antimicrobiano; diseño cruzado en función de la ruta de administración). Se determinarán sus concentraciones en dichos fluidos, por cromatografía líquida de alta precisión. Los resultados FC/FD para ambos medicamentos se compararán con parámetros recomendados por expertos para cada tipo de antimicrobiano y se utilizarán como medida para recomendar una terapéutica racional, fundamental para optimizar la posología, garantizar la eficacia clínica, y reducir al mínimo la selección y propagación de cepas resistentes de agentes patógenos. The production of milk of goat is considered the province of Cordoba, a productive alternative for the sustainable development and partner - economically of the population. There is a major demand of the domestic and international market of this milk, for what the producers must guarantee the safety and quality of the same one of agreement to the in force procedure. It is for it that the control and treatment of the different diseases performs vital importance so much to maximize the production of the herd as to expire with the safety demanded. In this context the mastitis goat is one of the diseases that affect the productivity of the sector, and to control her one of the measures to using is the therapeutics with antimicrobial. One will be employed at this project with marbofloxacine and cefquinome, establishing rational guidelines (effective and sure) for his employment in the affection to regional level. The indicators of efficiency will be fixed in agreement to the integrated parameters of pharmacokinetics (PK) and pharmacodinamics (PD). The latter (PK) will be calculated across the determination inhibitory minimal concentrations of bacterial strains isolated of mastitis goat in Córdoba. The parameters will be established pharmacokinetics to the only and multiple doses for the marbofloxacine (5 mg/kg the IV, IM) and cefquinome (2 mg/kg the IVth, IM and IMM), From samples of whey and milk of goats Anglo Nubian (n = 6 for antimicrobial; design crossed depending on the route of administration). Its concentrations will decide in the above mentioned fluids, for liquid chromatography of high precision. The results PK/PD for both antimicrobial will be compared with parameters recommended by experts for every type of antimicrobial and will be in use as measure for recommending a rational, fundamental therapeutics for optimizing the dosage, for guaranteeing the clinical efficiency, and to reduce to the minimum the selection and spread of resistant of pathogenic agents.

The Irish pub as a third place : a sociological exploration of people, place and identity

There is considerable interest in alcohol in Irish society, yet minimal sociologcial understanding of its consumption, particularly of the sites where most drinking occurs: the country's 8750 pubs. Despite widespread public discussions on the role of the pub, there is scant social science evidence to better inform debate. Pubs are central to Irish community and are key sites of social interaction. American sociologist Ray Oldenburg has argued that "third places" (neither workplace nor home) are crucial to the maintenance of the community and the enhancement of social capital. According to Oldenburg, the role of the third place in the community is to provide continuity, regularity, a sense of place - all of which conceptually contribute to the construction of the self, the projection of the self within the public sphere, the distribution of social capital and the generation of a collective identity. The pub is the archetypal third place, but Oldenburg is concerned that modern pubs are less able to provide this vital function. Social scientists have suggested that community is in a state of fragmentation and decline due to changes in modes of social interaction and a decrease in shared spaces, resulting in a weakened connection to place. Community without propinquity has been characterised by social alienation, fragmentation and what Oldenburg refers to as the "problem of place" (13). Third places, and thus the Irish pub, have been particularly affected. In order to increase the sociological knowledge of the pub in Ireland, this project critically engages with the pub to assess the importance that public drinking houses have in the everyday. Moreover, this research sets out to investigate the people/place relationship using the pub as an investigative lens and examine the ways in which people shape place, place shapes people and how that relationship is implicated in the construction of irish identities. Furthermore, this is also an articulation of a cultural shift within Ireland and Irish places whose effects are deep and multi-layered. This project aims to explore the development of the contemporary geography of identity as the irish pub as a third place is transformed or disappears from the social landscape.

Comparison between MDCT and Grayscale IVUS in a Quantitative Analysis of Coronary Lumen in Segments with or without Atherosclerotic Plaques

Background: The diagnostic accuracy of 64-slice MDCT in comparison with IVUS has been poorly described and is mainly restricted to reports analyzing segments with documented atherosclerotic plaques. Objectives: We compared 64-slice multidetector computed tomography (MDCT) with gray scale intravascular ultrasound (IVUS) for the evaluation of coronary lumen dimensions in the context of a comprehensive analysis, including segments with absent or mild disease. Methods: The 64-slice MDCT was performed within 72 h before the IVUS imaging, which was obtained for at least one coronary, regardless of the presence of luminal stenosis at angiography. A total of 21 patients were included, with 70 imaged vessels (total length 114.6 ± 38.3 mm per patient). A coronary plaque was diagnosed in segments with plaque burden > 40%. Results: At patient, vessel, and segment levels, average lumen area, minimal lumen area, and minimal lumen diameter were highly correlated between IVUS and 64-slice MDCT (p < 0.01). However, 64-slice MDCT tended to underestimate the lumen size with a relatively wide dispersion of the differences. The comparison between 64-slice MDCT and IVUS lumen measurements was not substantially affected by the presence or absence of an underlying plaque. In addition, 64-slice MDCT showed good global accuracy for the detection of IVUS parameters associated with flow-limiting lesions. Conclusions: In a comprehensive, multi-territory, and whole-artery analysis, the assessment of coronary lumen by 64-slice MDCT compared with coronary IVUS showed a good overall diagnostic ability, regardless of the presence or absence of underlying atherosclerotic plaques.

Clinical Coronary In-Stent Restenosis Follow-Up after Treatment and Analyses of Clinical Outcomes

Background: Clinical in-stent restenosis (CISR) is the main limitation of coronary angioplasty with stent implantation. Objective: Describe the clinical and angiographic characteristics of CISR and the outcomes over a minimum follow-up of 12 months after its diagnosis and treatment. Methods: We analyzed in 110 consecutive patients with CISR the clinical presentation, angiographic characteristics, treatment and combined primary outcomes (cardiovascular death, nonfatal acute myocardial infarction [AMI]) and combined secondary (unstable angina with hospitalization, target vessel revascularization and target lesion revascularization) during a minimal follow-up of one year. Results: Mean age was 61 ± 11 years (68.2% males). Clinical presentations included acute coronary syndrome (ACS) in 62.7% and proliferative ISR in 34.5%. CISR was treated with implantation of drug-eluting stents (DES) in 36.4%, Bare Metal Stent (BMS) in 23.6%, myocardial revascularization surgery in 18.2%, balloon angioplasty in 15.5% and clinical treatment in 6.4%. During a median follow-up of 19.7 months, the primary outcome occurred in 18 patients, including 6 (5.5%) deaths and 13 (11.8%) AMI events. Twenty-four patients presented a secondary outcome. Predictors of the primary outcome were CISR with DES (HR = 4.36 [1.44–12.85]; p = 0.009) and clinical treatment for CISR (HR = 10.66 [2.53–44.87]; p = 0.001). Treatment of CISR with BMS (HR = 4.08 [1.75–9.48]; p = 0.001) and clinical therapy (HR = 6.29 [1.35–29.38]; p = 0.019) emerged as predictors of a secondary outcome. Conclusion: Patients with CISR present in most cases with ACS and with a high frequency of adverse events during a medium-term follow-up.

Carlos Chagas Discoveries as a Drop Back to Scientific Construction of Chronic Chagas Heart Disease

Abstract The scientific construction of chronic Chagas heart disease (CCHD) started in 1910 when Carlos Chagas highlighted the presence of cardiac arrhythmia during physical examination of patients with chronic Chagas disease, and described a case of heart failure associated with myocardial inflammation and nests of parasites at autopsy. He described sudden cardiac death associated with arrhythmias in 1911, and its association with complete AV block detected by Jacquet's polygraph as Chagas reported in 1912. Chagas showed the presence of myocardial fibrosis underlying the clinical picture of CCHD in 1916, he presented a full characterization of the clinical aspects of CCHD in 1922. In 1928, Chagas detected fibrosis of the conductive system, and pointed out the presence of marked cardiomegaly at the chest X-Ray associated with minimal symptomatology. The use of serological reaction to diagnose CCHD was put into clinical practice in 1936, after Chagas' death, which along with the 12-lead ECG, revealed the epidemiological importance of CCHD in 1945. In 1953, the long period between initial infection and appearance of CCHD was established, whereas the annual incidence of CCHD from patients with the indeterminate form of the disease was established in 1956. The use of heart catheterization in 1965, exercise stress testing in 1973, Holter monitoring in 1975, Electrophysiologic testing in 1973, echocardiography in 1975, endomyocardial biopsy in 1981, and Magnetic Resonance Imaging in 1995, added to the fundamental clinical aspects of CCHD as described by Carlos Chagas.

Efficiency Comparison of DFT/IDFT Algorithms by Evaluating Diverse Hardware Implementations

In this paper we investigate various algorithms for performing Fast Fourier Transformation (FFT)/Inverse Fast Fourier Transformation (IFFT), and proper techniques for maximizing the FFT/IFFT execution speed, such as pipelining or parallel processing, and use of memory structures with pre-computed values (look up tables -LUT) or other dedicated hardware components (usually multipliers). Furthermore, we discuss the optimal hardware architectures that best apply to various FFT/IFFT algorithms, along with their abilities to exploit parallel processing with minimal data dependences of the FFT/IFFT calculations. An interesting approach that is also considered in this paper is the application of the integrated processing-in-memory Intelligent RAM (IRAM) chip to high speed FFT/IFFT computing. The results of the assessment study emphasize that the execution speed of the FFT/IFFT algorithms is tightly connected to the capabilities of the FFT/IFFT hardware to support the provided parallelism of the given algorithm. Therefore, we suggest that the basic Discrete Fourier Transform (DFT)/Inverse Discrete Fourier Transform (IDFT) can also provide high performances, by utilizing a specialized FFT/IFFT hardware architecture that can exploit the provided parallelism of the DFT/IDF operations. The proposed improvements include simplified multiplications over symbols given in polar coordinate system, using sinе and cosine look up tables, and an approach for performing parallel addition of N input symbols.

Verwendung von acetyliertem Distärkephosphat und Distärkeadipat als Stabilisator in einer Lachscreme auf Emulsionsbasis

The present Bachelor thesis gives an overview of the influence of some starch esters (acetylated distarch phosphate (E 1414) and adipate (E1422)) as stabilizing agents in a salmon-emulsion-cream. The aim of this work was the development of an optimal recipe. Different concentrations of starches were used in combination with xanthan gum. The methods were used to describe the rheological, microphotographical, microbiological, chemical and sensorial characteristics of the spread. The analysis of determination and development of droplet size showed a significant reduction in coalescence process. Rheological experiments indicated that high concentrations of E 1414 are necessary getting a slightly higher viscosity than in case of the E 1422 creams. The microbiological results showed minimal differences. All tested samples showed high stability against oxidation. For the use of a new recipe acetylated distarch adipate is the better choice in this case.

Rutura do baço na febre tifóide

A case of typhus levissimus or splenotyphus is reported whose death ocurred approximately at the beginning of the 2nd week as a consequence of rupture of the spleen and hematoperitoneum (2 liters). Acute perisplenitis and intracapsular hemorrhages as well as marked distention of the capsule pertinent to the extreme increase in volume of the organ in this stage of the disease are thought to be the changes concerned with the rupture of the organ, possibly influenced by overlooked minimal trauma.
