Síndrome Guillain Barré y ausencia de IgA
Introducción El síndrome Guillain-Barré se caracteriza por la presencia de una polirradiculoneuropatía aguda, rápidamente progresiva y simétrica, con afectación predominante de la función motora, y que suele acompañarse ...
Aproximació ecològica a la mortalitat per accidents de trànsit a Catalunya (1983-1985)
A partir de la distribució geogràfica de Catalunya en 9 regions, s'estudia la correlació ecològica existent entre la mortalitat per accident de vehicles de motor, estandaritzada per edat (índex de mortalitat estàndard [IME] ...

DNA methylation profiles and their relationship with cytogenetic status in adult acute myeloid leukemia
Background: Aberrant promoter DNA methylation has been shown to play a role in acute myeloid leukemia (AML) pathophysiology. However, further studies to discuss the prognostic value and the relationship of the epigenetic ...
Characterization, localization and comparison of c-Kit+ lung cells in never smokers and smokers with and without COPD
Background: c-Kit + lung stem cells have been described in the human healthy lung. Their potential relation with smoking and/or chronic obstructive pulmonary disease (COPD) is unknown. Methods: We characterized and compared ...
Divergent mutational processes distinguish hypoxic and normoxic tumours
Many primary tumours have low levels of molecular oxygen (hypoxia), and hypoxic tumours respond poorly to therapy. Pan-cancer molecular hallmarks of tumour hypoxia remain poorly understood, with limited comprehension of ...

Epigenetic Activation of SOX11 in Lymphoid Neoplasms by Histone Modifications
Recent studies have shown aberrant expression of SOX11 in various types of aggressive B-cell neoplasms. To elucidate the molecular mechanisms leading to such deregulation, we performed a comprehensive SOX11 gene expression ...
Surveillance of influenza B severe hospitalized cases during 10 seasons in Catalonia: Does the lineage make a difference?
Influenza B viruses circulate in two lineages (B/Victoria and B/Yamagata). Although classically affecting children, recently it has shown a high rate of infection and increased hospitalization in the elderly. To describe ...
Foreign-Medical-School Graduates object to the VISA Qualifiying Examination
To the editor; The Visa Qualifying Examination is a two-day test composed of approximately 950 multiple-choice questions conerneing the basic and clinical sciences....
Parameter estimation of Poisson generalized linear mixed models based on three different statistical principles: a simulation study
Generalized linear mixed models are flexible tools for modeling non-normal data and are usefulfor accommodating overdispersion in Poisson regression models with random effects. Theirmain difficulty resides in the parameter ...
Endometrial carcinoma, grossing and processing issues: recommendations of the International Society of Gynecologic Pathologists.
Endometrial cancer is the most common gynecologic neoplasm in developed countries; however, updated universal guidelines are currently not available to handle specimens obtained during the surgical treatment of patients ...

On the use of fast blue, fluoro-gold and diamidino yellow for retrograde tracing after peripheral nerve injury: uptake, fading, dye interactions, and toxicity
The usefulness of three retrograde fluorescent dyes for tracing injured peripheral axons was investigated. The rat sciatic was transected bilaterally and the proximal end briefly exposed to either Fast Blue (FB), Fluoro-Gold ...
Sindrome de regresión caudal
El síndrome de regresión caudal o de agenesia sacra se caracteriza por un déficit funcional de los esfínteres y de la muscultatura de los miembros inferiores. Se suele asociar con otras malformaciones, como son las ...
Monitoring treatment of field cancerisation with 3% diclofenac sodium 2.5% hyaluronic acid by reflectance confocal microscopy: a histologic correlation
Visual inspection may fail to accurately evaluate field cancerisation (subclinical actinic keratoses [AKs]). We aimed to describe field cancerisation by confocal reflectance microscopy and changes induced by the application ...
Clonal Spread and Intra- and Inter-Species Plasmid Dissemination Associated With Klebsiella pneumoniae Carbapenemase-Producing Enterobacterales During a Hospital Outbreak in Barcelona, Spain
Objectives: The study aimed to characterize the clonal spread of resistant bacteria and dissemination of resistance plasmids among carbapenem-resistant Enterobacterales at a tertiary hospital in Catalonia, Spain. Methods: ...
Frequent and simultaneous epigenetic inactivation of TP53 pathway genes in acute lymphoblastic leukemia
Aberrant DNA methylation is one of the most frequent alterations in patients with Acute Lymphoblastic Leukemia (ALL). Using methylation bead arrays we analyzed the methylation status of 807 genes implicated in cancer in a ...
C-reactive protein in outpatients with acute exacerbation of COPD: its relationship with microbial etiology and severity
BACKGROUND: C-reactive protein (CRP) measurement has proven valuable for detecting exacerbations, but its usefulness in predicting etiology remains controversial. Likewise, its ...
