Gene regulatory networks elucidating Huanglongbing disease mechanisms
2013
Next-generation sequencing was exploited to gain deeper insight into the response to infection by Candidatus liberibacter asiaticus (CaLas), especially the immune disregulation and metabolic dysfunction caused by source-sink disruption. Previous fruit transcriptome data were compared with additional RNA-Seq data in three tissues: immature fruit, and young and mature leaves. Four categories of orchard trees were studied: symptomatic, asymptomatic, apparently healthy, and healthy. Principal component analysis found distinct expression patterns between immature and mature fruits and leaf samples for all four categories of trees. A predicted protein - protein interaction network identified HLB-…
Transcriptome profiling of citrus fruit response to huanglongbing disease.
2010
Huanglongbing (HLB) or "citrus greening" is the most destructive citrus disease worldwide. In this work, we studied host responses of citrus to infection with Candidatus Liberibacter asiaticus (CaLas) using next-generation sequencing technologies. A deep mRNA profile was obtained from peel of healthy and HLB- affected fruit. It was followed by pathway and protein-protein network analysis and quantitative real time PCR analysis of highly regulated genes. We identified differentially regulated pathways and constructed networks that provide a deep insight into the metabolism of affected fruit. Data mining revealed that HLB enhanced transcription of genes involved in the light reactions of phot…
Network Analysis of Persistent Somatic Symptoms in Two Clinical Patient Samples
2021
OBJECTIVE Previous attempts to group persistent somatic symptoms (PSS) with factor-analytic approaches have obtained heterogeneous results. An alternative approach that seems to be more suitable is the network theory. Compared to factor analysis, which focuses on the underlying factor of symptoms, network analysis focuses on the dynamic relationships and interactions among different symptoms. The main aim of this study is to apply the network approach to examine the heterogeneous structure of PSS within two clinical samples. METHODS The first dataset consisted of N = 254 outpatients who were part of a multicentre study. The second dataset included N = 574 inpatients, both with somatoform di…
Do aetiology, age and cogntive reserve affect executive performance?
2017
Background: The behavioral effect of frontal lesions may be influenced by confounding factors such as aetiology, age and cogntive reserve. Yet no studies have investigated their effects on patients with focal lesions. Objective: Is the grouping of patients with frontal lesions caused by stroke or tumours methodologically appropriate; does age affect cognitive performance, can cognitive reserve protect against cognitive impairment? Patients and Methods/Material and Methods: Cognitive performance was compared across a large sample of frontal patients with stroke, high or low grade tumour, or meningioma. The effect of age, education and NART IQ on the cognitive performance of patients with foc…
Complicanze in chirurgia tiroidea: ipoparatiroidismo sintomatico post-operatorio.Incidenza, note di tecnica chirurgica, prevenzione e trattamento.
2006
Introduction: Total thyroidectomy has a definite role in the management of malignant and benign thyroid disorders, with minimal complications and rare postoperative mortality. Even though thyroid surgery is quite safe, mechanical damage, devascularization or inadvertent removal of the parathyroid glands are possible. The aim of this study is to report report the personal surgical experience and to define some of the pathologic and clinical characteristics of unintentional parathyroidectomy and post-thyroidectomy hypocalcemia Materials and methods: A retrospective-observational study was carried on 313 thyroidectomies from January 2000 to January 2004 (60 males and 253 females), mean age 41 …
State of the art and clinical recommendations in periapical implant lesions. 9th Mozo-Grau Ticare Conference in Quintanilla, Spain.
2016
This manuscript summarizes the statements and clinical recommendations in periapical implant lesions, as per the state of the art and expert opinion agreement among the participants in the 9th Mozo-Grau Conference 2016 held in Quintanilla (Valladolid, Spain). The current status of the concept, frequency, etiology, diagnosis, clinical classification, surgical procedure and prognosis are described. If following implant placement localized pain develops in the periapical area, with or without radiographic changes, the diagnosis of periapical implant lesion should be suspected. It is important to monitor the condition in order to identify any change in its evolution. Radiological changes in the…
Contingency plan for the intensive care services for the COVID-19 pandemic☆☆☆
2020
In January 2020, the Chinese authorities identified a new virus of the Coronaviridae family as the cause of several cases of pneumonia of unknown aetiology. The outbreak was initially confined to Wuhan City, but then spread outside Chinese borders. On 31 January 2020, the first case was declared in Spain. On 11 March 2020, The World Health Organization (WHO) declared the coronavirus outbreak a pandemic. On 16 March 2020, there were 139 countries affected. In this situation, the Scientific Societies SEMICYUC and SEEIUC, have decided to draw up this Contingency Plan to guide the response of the Intensive Care Services. The objectives of this plan are to estimate the magnitude of the problem a…
Depression bei Kindern und Jugendlichen: Prävalenz, Diagnostik, ätiologische Faktoren, Geschlechtsunterschiede, therapeutische Ansätze
2007
Die Prävalenzraten für die verschiednen Formen von Depression (depressiven Stimmungen, depressiven Syndromen und Major Depression) haben in den letzten Jahren zugenommen, die Geschlechtsunterschiede mit deutlich höheren Raten für Mädchen haben sich erhöht. Als ätiologische Faktoren für das Auftreten von Depression werden u. a. zunehmende Stressfaktoren, dysfunktionale Bewältigungsstile, ein negatives Körperkonzept und unsichere Bindungsmuster genannt. Unter den verschiedenen therapeutischen Ansätzen hat sich die psychoananlytische Behandlungsmethode als die umfassendste erwiesen. Schlüsselwörter Prävalenzraten - Komorbidität - Stress - Coping - Körperkonzept - Bindung Prevalence rates of th…
Diagnóstico etilógico de la disfunción ventricular izquierda con tomografia computerizada: comparación con coronariografía y cardiorresonancia
2012
[EN] Introduction and objectives To evaluate the capability of multidetector computed tomography to diagnose the coronary etiology of left ventricular dysfunction compared with using invasive coronary angiography and magnetic resonance. Methods Forty consecutive patients with left ventricular dysfunction of uncertain etiology underwent invasive coronary angiography and contrast magnetic resonance. All patients were evaluated with multidetector computed tomography including coronary calcium presence and score, noninvasive coronary angiography, and myocardial tissue assessment. Results The sensitivity and specificity of the presence of coronary calcium to identify left ventricular dysfunction…
Cri du chat syndrome: A critical review
2009
A new syndrome was identified in 1963, when Lejeune et al. reported a genetic disease resulting from a partial or total deletion on the short arm of chromosome 5 (5p-) and named it the cri du chat syndrome (CdCS). This term makes reference to the main clinical feature of the syndrome, a high-pitched monochromatic cat-like crying, that usually disappears in the first years of life. CdCS is one of the most common chromosomal deletion syndromes in humans, with an incidence of 1:15.000-1:50.000 live-births. Our purpose was to review different aspects of this syndrome (concept, epidemiology, aetiology, clinical features,diagnostic methods and prognosis) emphasizing both: the breakthrough in this…
