Summer Vacations not Only a Memory for Life, but Also a Rare Infection

Introduction: Rhinoscleroma is a rare, chronic, granulomatous disease that most frequently affects the upper respiratory tract, especially the nasal cavity and sometimes extends through the lower respiratory tract. Is associated with Klebsiella rhinoscleromatis, which is endemic in certain geographic regions namely Central America. The pathogenesis and risk factors remain unclear. Clinical case: We report a five years Old Portuguese boy, previously healthy, brought to the Emergency Department with epistaxis, without other accompanying signs or symptoms. The Otorhinolaryngologist (ORL) performed rhinoscopy and identified an intranasal bleeding mass. The MRI revealed an intranasal mass with extension to the ethmoid bone sinus, and performed biopsy. The histopathology was vital, making the diagnosis of Rhinoscleroma. The child had traveled abroad for the first time on vacations a year before to Dominican Republic. The bacteriologic exam identified a Klebsiella spp. sensible to the association of amoxicillin and clavulanic acid. Blood test performed excluded association of immunodeficiency. Since it’s a rare disease genetic study are under course. Monthly evaluation by ORL and pediatrician was performed which documented progressive reduction until total disappearing of the macro and microscopic lesion, and negative bacteriologic exam. Six months of antibiotic therapy were completed without any known secondary effects. The child remained asymptomatic up to the last visit, 3 months following treatment and has shown no evidence of recurrence. Conclusion: Globalization and free transit of people to areas far from origin countries here some rare diseases are endemic brings a new challenge to modern medicine. Sometimes vacations bring more than memories.

A logical foundation for session-based concurrent computation

Linear logic has long been heralded for its potential of providing a logical basis for concurrency. While over the years many research attempts were made in this regard, a Curry-Howard correspondence between linear logic and concurrent computation was only found recently, bridging the proof theory of linear logic and session-typed process calculus. Building upon this work, we have developed a theory of intuitionistic linear logic as a logical foundation for session-based concurrent computation, exploring several concurrency related phenomena such as value-dependent session types and polymorphic sessions within our logical framework in an arguably clean and elegant way, establishing with relative ease strong typing guarantees due to the logical basis, which ensure the fundamental properties of type preservation and global progress, entailing the absence of deadlocks in communication. We develop a general purpose concurrent programming language based on the logical interpretation, combining functional programming with a concurrent, session-based process layer through the form of a contextual monad, preserving our strong typing guarantees of type preservation and deadlock-freedom in the presence of general recursion and higher-order process communication. We introduce a notion of linear logical relations for session typed concurrent processes, developing an arguably uniform technique for reasoning about sophisticated properties of session-based concurrent computation such as termination or equivalence based on our logical approach, further supporting our goal of establishing intuitionistic linear logic as a logical foundation for sessionbased concurrency.

Rotavirus G2P[4] and G2P[4]+[6] infections during norovirus gastroenteritis outbreak: summer season 2010, Brazil

IntroductionThis study aimed to monitor the seasonality of rotavirus infection, and gain insight into the variability of Brazilian strains.MethodsA total of 28 stool samples were analyzed from 698 revised cases of gastroenteritis during a norovirus outbreak in the summer of 2010 in Guarujá, Brazil. Diagnosis was performed using enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and sequencing.ResultsRotavirus infection was detected in 17.9% (5/28) of samples; 4 samples were G2P[4] genotype, and one G2P[4]+P[6] genotype. G2 and P[4] sequences showed a genetic relationship to strains from India and Russia, respectively.ConclusionsThe seasonal pattern of rotavirus may be a consequence of human activity apart from climate factors.

Diurnal variability of rainfall in southwest Amazonia during the LBA-TRMM field campaign of the austral summer of 1999

The TRMM-LBA field campaign was held during the austral summer of 1999 in southwestern Amazonia. Among the major objectives, was the identification and description of the diurnal variability of rainfall in the region, associated with the different rain producing weather systems that occurred during the January-February season. By using a network of 40 digital rain gauges implemented in the state of Rondônia, and together with observations and analyses of circulation and convection, it was possible to identify details of the diurnal cycle of rainfall and the associated rainfall mechanisms. Rainfall episodes were characterized by regimes of "low-level easterly" and "westerly" winds in the context of the large-scale circulation. The westerly regime is related to an enhanced South Atlantic Convergence Zone (SACZ) and an intense and/or wide Low Level Jet (LLJ) east of the Andes, which can extend eastward towards Rondônia, even though some westerly regime episodes also show a LLJ that remains close to the foothill of the Andes. The easterly regime is related to easterly propagating systems (e.g. squall-lines) with possible weakened or less frequent LLJs and a suppressed SACZ. Diurnal variability of rainfall during westerly surface wind regime shows a characteristic maximum at late afternoon followed by a relatively weaker second maximum at early evening (2100 Local Standard Time LST). The easterly regime composite shows an early morning maximum followed by an even stronger maximum in the afternoon.

Disposición plasmática y residuos tisulares de marbofloxacina en truchas arco iris (oncorhynchus mykiss) en condiciones estivales e invernales. Plasmatic disposition and tissue residues of marbofloxacin in rainbow trouts (oncorhynchus mykiss) in summer and winter conditions

Los sistemas intensivos de producción, predisponen en los peces a la presentación de diversas enfermedades, lo que demanda el empleo de antimicrobianos para mantener la salud de los lotes de cultivo. En tal sentido es importante contar con información local en cuanto al comportamiento cinético a los efectos de determinar una adecuada dosificación de los antimicrobianos empleados y con esta información, establecer los periodos de resguardo necesarios para evitar la presencia violativa de estos fármacos en el animal destinado a consumo humano. En el presente proyecto se propone efectuar un estudio farmacocinético de concentraciones plasmáticas y tisulares alcanzadas y establecer los periodos de resguardo para marbofloxacina, antimicrobiano del cual no se tienen antecedentes regionales en cuanto a su disposición a diferentes temperaturas como las que condicionan las estaciones de verano e invierno, de marcada variación en la provincia, modificando la actividad metabólica de los peces. La concreción de este proyecto permitirá entregar conocimientos concretos y de aplicación directa en la cría intensiva de la trucha arco iris (Oncorhynchus mykiss) en diferentes condiciones ambientales, al contarse con la información necesaria para una adecuada dosificación y periodos de resguardo necesarios para evitar el residuo de este fármaco. Además, permitirá consolidar una línea de investigación dentro de la acuicultura muy poco desarrollada actualmente en el país. Intensive production systems predispose fishes to diverse diseases, which demands antimicrobial use for health maintenance in the lots of culture. In such sense it is important to have local information of the kinetic behavior to determine a suitable dosing of the antimicrobials employed, and on this information, to establish withdrawal periods to avoid the violative presence of these drugs in animals for human consumption. The present project will carry out a pharmacokinetic study of plasmatic and tissue concentrations to establish the withdrawal period for marbofloxacin, being known that temperature, modify the metabolic activity of the fish, and there are no local antecedents of disposition at different temperatures in summer and winter for this antimicrobial. The concretion of this project will allow to give concrete knowledge of direct application in intensive production of rainbow trout (Oncorhynchus mykiss), in different environmental conditions, counting with the necessary information for a suitable dosification and withdrawal periods to avoid residues of this drug. In addition, it will allow to consolidate an investigation line in acuiculture, not much developed in our country.

Effects of One Resistance Exercise Session on Vascular Smooth Muscle of Hypertensive Rats

AbstractBackground:Hypertension is a public health problem and increases the incidence of cardiovascular diseases.Objective:To evaluate the effects of a resistance exercise session on the contractile and relaxing mechanisms of vascular smooth muscle in mesenteric arteries of NG-nitro L-arginine methyl ester (L-NAME)-induced hypertensive rats.Methods:Wistar rats were divided into three groups: control (C), hypertensive (H), and exercised hypertensive (EH). Hypertension was induced by administration of 20 mg/kg of L-NAME for 7 days prior to experimental protocols. The resistance exercise protocol consisted of 10 sets of 10 repetitions and intensity of 40% of one repetition maximum. The reactivity of vascular smooth muscle was evaluated by concentration‑response curves to phenylephrine (PHEN), potassium chloride (KCl) and sodium nitroprusside (SNP).Results:Rats treated with L-NAME showed an increase (p < 0.001) in systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) compared to the initial period of induction. No difference in PHEN sensitivity was observed between groups H and EH. Acute resistance exercise reduced (p < 0.001) the contractile response induced by KCl at concentrations of 40 and 60 mM in group EH. Greater (p < 0.01) smooth muscle sensitivity to NPS was observed in group EH as compared to group H.Conclusion:One resistance exercise session reduces the contractile response induced by KCl in addition to increasing the sensitivity of smooth muscle to NO in mesenteric arteries of hypertensive rats.
