Update in dental implant periapical surgery
2006
La lesión periapical implantaria es una patología infecciosa-inflamatoria localizada alrededor del ápice del implante. Puede ser provocada por diversas causas, entre ellas: la contaminación en el momento de la instrumentación, el sobrecalentamiento óseo y la presencia de una patología preexistente en el hueso. Su diagnóstico es sintomático y radiográfico, y puede observarse una imagen radiolúcida alrededor del periápice. Clasificamos las lesiones según el momento evolutivo en lesión aguda (no supurada y supurada) y crónica o absceso periapical. El tratamiento de esta patología es la cirugía periapical con legrado e irrigación en la fase aguda; y la extracción del implante cuando se involucr…

Effect of Fibrin Sealant on Seroma Formation Post-Incisional Hernia Repair
2020
Background: Development of seroma after incisional hernia repair is a common complication. Our study aims to compare the outcomes of sublay incisional hernia repairs with or without spray instillation of fibrin glue. Methods: We enrolled fifty patients undergoing incisional hernia repair. In all patients a suction drain was placed in the subcutaneous space. In one group (FG) 4 ml fibrin glue was instilled in the subcutaneous space. In the control group (C) patients did not receive any prevention measure. Wounds fluids were collected on post-operative day 1 (POD) and once daily until drain removal. All patients were followed up by ultrasound on POD 15, 20, 40, 60. Results: Drain fluid produc…
Retirada del tratamiento betabloqueante en pacientes con insuficiencia cardíaca con función sistólica preservada e incompetencia cronotrópica. Efecto…
2022
La insuficiencia cardiaca con fracción de eyección preservada presenta una fisiopatología compleja y multifactorial. Entre los potenciales mecanismos, la incompetencia cronotrópica podría contribuir a la limitación de la capacidad funcional. Cabe reseñar que un gran porcentaje de pacientes con insuficiencia cardiaca con fracción de eyección preservada reciben tratamiento con betabloqueantes a pesar de la falta de evidencia en este perfil de pacientes. Con estas premisas, la hipótesis fue que la retirada del tratamiento betabloqueante en pacientes con insuficiencia cardiaca con fracción de eyección preservada, con criterios de estabilidad clínica, en tratamiento crónico y estable con betablo…
Droplet digital PCR as a tool for investigating dynamics of cryptic symbionts
2021
Abstract Interactions among symbiotic organisms and their hosts are major drivers of ecological and evolutionary processes. Monitoring the infection patterns among natural populations and identifying factors affecting these interactions are critical for understanding symbiont–host relationships. However, many of these interactions remain understudied since the knowledge about the symbiont species is lacking, which hinders the development of appropriate tools. In this study, we developed a digital droplet PCR (ddPCR) assay based on apicomplexan COX1 gene to detect an undescribed agamococcidian symbiont. We show that the method gives precise and reproducible results and enables detecting cryp…
Anomalous and normal Hall effect in hydrogenated amorphous Si prepared by plasma enhanced chemical vapor deposition
2010
The double sign anomaly of the Hall coefficient has been studied in p -doped and n -doped hydrogenated amorphous silicon grown by plasma enhanced chemical vapor deposition and annealed up to 500 °C. Dark conductivity as a function of temperature has been measured, pointing out a conduction mechanism mostly through the extended states. Anomalous Hall effect has been observed only in the as-deposited n -doped film, disappearing after annealing at 500 °C, while p -doped samples exhibit normal Hall effect. When Hall anomaly is present, a larger optical band gap and a greater Raman peak associated with Si-H bond are measured in comparison with the cases of normal Hall effect. The Hall anomaly wi…
Sense of coherence and health among home-dwelling older people.
2010
Sense of coherence (SOC) is important for maintaining health. The aim of this study was to investigate if the SOC experience among home-dwelling physically active older people differs from that of hospital patients with the same age and sex. Data were collected with questionnaires and structured interviews containing Antonovsky’s SOC scale in an age- and sex-matched study group (n=160). Non-parametric statistical analyses were performed. No differences were found in SOC between home-dwelling individuals and patients. Ninety-five percent of the home-dwelling individuals perceived themselves as being in good health and 42.5% among the patients (p<0.001). SOC and disease were predictors fo…
The enrichment ratio of atomic contacts in crystals, an indicator derived from the Hirshfeld surface analysis
2014
An enrichment ratio is derived from the decomposition of the crystal contact surface between pairs of interacting chemical species. The propensity of different contact types to form is investigated.
Iron Induces Proliferation and Morphogenesis in Primmorphs from the Marine SpongeSuberites domuncula
2002
Dissociated cells from marine demosponges retain their proliferation capacity if they are allowed to form special aggregates, the primmorphs. On the basis of incorporation studies and septin gene expression, we show that Fe3+ ions are required for the proliferation of cells in primmorphs from Suberites domuncula. In parallel, Fe3+ induced the expression of ferritin and strongly stimulated the synthesis of spicules. This result is supported by the finding that the enzymatic activity of silicatein, converting organosilicon to silicic acid, depends on Fe3+. Moreover, the expression of a scavenger receptor molecule, possibly involved in the morphology of spicules, depends on the presence of Fe3…
