Analysis of vitamin D levels in patients with and without statin-associated myalgia — A systematic review and meta-analysis of 7 studies with 2420 pa…
2014
article i nfo Introduction: VitaminD (vitD)deficiencymay beassociatedwith anincreased riskof statin-related symptomatic myalgia in statin-treated patients. The aim of this meta-analysis was to substantiate the role of serum vitamin D levels in statin-associated myalgia. Methods: The search included PUBMED, Cochrane Library, Scopus, and EMBASE from January 1, 1987 to April 1, 2014 to identify studies that investigated the impact of vit D levels in statin-treated subjects with and without myalgia. Two independent reviewers extracted data on study characteristics, methods and outcomes. Quantita- tive data synthesis was performed using a fixed-effect model. Results: The electronic search yielde…
Abstract 18967: Analysis of Vitamin D Levels in Patients With and Without Statin-induced Myalgia - A Systematic Review and Meta-analysis of 7 Studies…
2014
Introduction: Vitamin D (vit D) deficiency may be associated with an increased risk of statin-related muscle complaints, and symptomatic myalgia in statin-treated patients. Hypothesis: The aim of this meta-analysis was to investigate whether subjects with statin-induced myalgia have lower serum vit D levels compared with those who are asymptomatic. Methods: We searched PubMed, Web of Science, Cochrane Library, Scopus and EMBASE (up to March 2014) to identify studies that investigated the impact of vit D levels in statin-treated subjects with and without myalgia. Two independent reviewers extracted data on study characteristics, methods and outcomes. Results: The electronic search yielded 4…
Microwave-assisted synthesis of semiconductor nanoparticles in water/oil microemulsion
2005
Stable CdS and ZnS nanoparticles with exalted luminescence properties have been obtained in water/sodium bis (2-ethylhexyl) sulfosuccinate (AOT)/n-heptane microemulsion using microwave in order to take away selectively water molecules from microemulsion system. The nanoparticles synthesis was performed using a microwave exposure set-up opportunely assembled that allows irradiating the reactor with microwave of 2.45 GHz maintaining constant the temperature. The nanoparticles growth kinetics, as a function of irradiation time, was performed by means of UV-Vis spectroscopy. Information about the structural changes that microemulsion undergoes when irradiated with microwave was obtained by mean…
Preparation of Nd:YAG Nanopowder in a Confined Environment
2007
Nanopowder of yttrium aluminum garnet (YAG, Y3Al5O12) doped with neodymium ions (Nd:YAG) was prepared in the water/cetyltrimethylammonium bromide/1-butanol/n-heptane system. Aluminum, yttrium, and neodymium nitrates were used as starting materials, and ammonia was used as a precipitating agent. Coprecipitate hydroxide precursors where thermally treated at 900 degrees C to achieve the garnet phase. The starting system with and without reactants was characterized by means of the small-angle neutron scattering technique. The system, without reactants, is constituted by a bicontinuous structure laying near the borderline with the lamellar phase region. The introduction of nitrates stabilizes th…
Chemical Ecology of Floral Resources in Conservation Biological Control.
2023
Conservation biological control aims to enhance populations of natural enemies of insect pests in crop habitats, typically by intentional provision of flowering plants as food resources. Ideally, these flowering plants should be inherently attractive to natural enemies to ensure that they are frequently visited. We review the chemical ecology of floral resources in a conservation biological control context, with a focus on insect parasitoids. We highlight the role of floral volatiles as semiochemicals that attract parasitoids to the food resources. The discovery that nectar-inhabiting microbes can be hidden players in mediating parasitoid responses to flowering plants has highlighted the co…
Negative emotional state slows down movement speed : behavioral and neural evidence
2019
Background Athletic performance is affected by emotional state. Athletes may underperform in competition due to poor emotion regulation. Movement speed plays an important role in many competition events. Flexible control of movement speed is critical for effective athletic performance. Although behavioral evidence showed that negative emotion can influence movement speed, the nature of the relationship remains controversial. Thus, the present study investigated how negative emotion affects movement speed and the neural mechanism underlying the interaction between emotion processing and movement control. Methods The present study combined electroencephalography (EEG) technology with a cued-…
EVALUATING THE RISK OF HEPATITIS B REACTIVATION IN PATIENTS WITH HAEMATOLOGICAL MALIGNANCIES: IS THE SERUM HEPATITIS B PROFILE RELIABLE?
2009
Background/Aim: Patients with an occult hepatitis B virus (HBV) infection undergoing deep immunosuppression are potentially at risk of HBV reactivation. In order to assess whether a polymerase chain reaction (PCR) assay for HBV DNA in serum could be used to predict the reactivation of an occult HBV infection, we performed a retrospective study in a cohort of Sicilian patients with oncohaematological diseases. Methods: We studied by a highly sensitive ad hoc nested PCR for serum HBV DNA 75 HBsAg-negative oncohaematological patients requiring chemotherapy. Results: Thirty-three patients (44%) were HBV seronegative (anti-HBc and anti-HBs negative) and 42 patients (56%) were HBV seropositive (a…
Mapping the actions of prolactin in the brain: sexual dimorphism, steroid regulation and the neuroendocrinology of maternal behaviour
2017
El comportamiento maternal cumple la función de proteger a la descendencia en su periodo de mayor vulnerabilidad y asegurar su supervivencia y bienestar. Esta colección de conductas sociales será expresada por la madre exclusivamente durante el periodo postparto, como resultado de la modulación del sustrato neural responsable de la expresión de la conducta social y reproductiva. Los agentes que llevan a cabo dicha modulación para inducir la expresión del comportamiento maternal incluyen, entre otros, señales endocrinas específicas de la gestación y lactancia. Entre éstas destaca la prolactina, hormona adenohipofisaria estrechamente vinculada con la adaptación del organismo a la maternidad. …
La creencia en neuromitos en formación inicial de docentes de educación especial en Ecuador
2021
Se analizan las percepciones que tienen los futuros docentes ecuatorianos sobre neurociencia relacionada con la educación. Se presentó un cuestionario con 10 afirmaciones sobre las cuales debían indicar su nivel de conformidad. Los resultados demuestran una alta creencia en neuromitos, lo cual podría repercutir directamente en su futura práctica educativa.
La Neuroeducación moral y su aplicación en experiencias significativas para potenciar las competencias Éticas y Ciudadanas en alumnos de profesional …
2021
Trabajo de investigación-acción cuanti-cuali, etnográfica , con un alcance exploratorio-descriptivo, con herramientas de observación, encuesta y entrevista. El objetivo general fue determinar si realmente en las clases de ética, la neuroeducación moral y su aplicación en el trabajo comunitario con retos en escenarios reales y el análisis metacognitivo sobre el innatismo moral, potencia más las competencias éticas y ciudadanas en alumnos de profesional del ITESM, que en clases normales de ética con una sola inmersión en la comunidad. La importancia de la metacognición, en los procesos de aprendizaje y toma de decisiones en los dilemas éticos cotidianos que los alumnos van empoderando con la …
