Genomic Abnormalities Acquired in the Blastic Transformation of Splenic Marginal Zone B-cell Lymphoma

2003

Among 20 cases of typical splenic marginal zone lymphoma (SMZL), two cases had blastic transformation. The genetic mechanisms underlying the morphologic transformation were investigated by comparing genetic changes in initial and blastic phases. A complex karyotype including trisomy of 3q and genomic gain of 17q22-q24 was seen in both cases at diagnosis. However, the extra copy of 3q was lost during the transformation process in both tumors. Additionally, the Karpas 1718 cell line, which was derived from a patient with transformed SMZL and carried a trisomy of 3q, also evidenced the spontaneous loss of the extra 3q during the culturing process. Other acquired abnormalities observed exclusiv…

Fluorescence in situ hybridization analysis does not increase detection rate for trisomy 8 in chronic myelomonocytic leukemia.

2014

Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic stem cell neoplasm characterized by overlapping myelodysplastic and myeloproliferative features. Diagnosis is based on persistent mo...

Algunas reflexiones acerca de la stjue de 9 de julio de 2020 sobre los pactos novatorios en materia de cláusulas suelo

2021

The Sentence of the Court of Justice of the European Union of July 9, 2020 comes to answer the five questions that, in its preliminary question, the Court of First Instance and Instruction No. 3 of Teruel asks about the validity of the new agreements in the context of the floor clauses, establishing jurisprudential doctrine on this matter about which our Supreme Court had previously ruled in its Judgments of October 16, 2017, in the sense of considering the agreed floor clause null as a consequence of the novation agreement and, subsequently, those of April 11, 2018 and September 13, 2018 in the opposite direction, declaring that the novation agreement was valid. It is a long-awaited and in…

Valutazione dell’instabilità laterale di caviglia con RM dedicata in ortostatismo. Esperienza preliminare.

2010

SCOPO: Dimostrare l'utilità dell'esame in ortostatismo della caviglia con una RM dedicata nella valutazione di pazienti con evidenza clinica di instabilità laterale di caviglia. DISEGNO DELLO STUDIO: Retrospettivo. MATERIALI E METODI: Abbiamo valutato gli esami RM di caviglia di 29 pazienti, effettuati tra settembre 2008 e giugno 2009 con macchina RM dedicata da 0,25 Tesla (G-Scan, Esaote Spa, Genova, Italia). Sono state eseguite, con bobina ricevente dedicata per la caviglia, sequenze SE-T1 pesate, TSE-T2 pesate, 3D-Steady-State (SSE), e STIR, sia in posizione supina che ortostatica. Tre radiologi con esperienza in radiologia muscolo-scheletrica hanno valutato, in consenso, segni RM di ins…

Exploiting seeding of random number generators for efficient domain decomposition parallelization of dissipative particle dynamics

2013

Abstract Dissipative particle dynamics (DPD) is a new promising method commonly used in coarse-grained simulations of soft matter and biomolecular systems at constant temperature. The DPD thermostat involves the evaluation of stochastic or random forces between pairs of neighboring particles in every time step. In a parallel computing environment, the transfer of these forces from node to node can be very time consuming. In this paper we describe the implementation of a seeded random number generator with three input seeds at each step which enables the complete generation of the pairwise stochastic forces in parallel DPD simulations with minimal communication between nodes.

Social isolation from communities and child maltreatment: a cross-cultural comparison.

2003

Objective: The aim of this study is to determine: (1) the differences between Spanish and Colombian cultures in relation to community social support variables, and (2) the relationships between community social support variables and child maltreatment in both cultures. Method: The study was based on 670 nonabusive families and 166 abusive families. The parents were asked to complete the Community Social Support Questionnaire. This instrument measures community social support in terms of Community Integration and Satisfaction, membership in voluntary organizations and community participation, and use of Community Resources of Social Support. Results: Differences between both cultures were fo…

Visible but unreported: a case for the "not serious enough" cases of child maltreatment.

1995

This study examined the psychosocial characteristics of cases of child maltreatment labelled as "not serious enough." The sample consisted of cases of suspected physical abuse (N = 48), neglect (N = 13), and psychological maltreatment (N = 8) identified by teachers, and a nonabused comparison group (N = 283). Characteristics of children and their parents were evaluated at three ecological levels: individual, family, and social. Results indicated a poor personal and social adjustment of the children in the maltreatment groups, and suggest that the definition of cases of maltreatment as not serious enough does not represent the psychological reality of these children. Discriminant analysis in…

Chlorine partitioning in the lowermost Arctic vortex during the cold winter 2015/2016

2019

Activated chlorine compounds in the polar winter stratosphere drive catalytic cycles that deplete ozone and methane, whose abundances are highly relevant to the evolution of global climate. The present work introduces a novel dataset of in situ measurements of relevant chlorine species in the lowermost Arctic stratosphere from the aircraft mission POLSTRACC–GW-LCYCLE–SALSA during winter 2015/2016. The major stages of chemical evolution of the lower polar vortex are presented in a consistent series of high-resolution mass spectrometric observations of HCl and ClONO2. Simultaneous measurements of CFC-12 are used to derive total inorganic chlorine (Cly) and active chlorine (ClOx). The new data…

Chromatographic determination of caffeine in pharmaceutical formulations using micellar mobile phases

1996

An HPLC procedure is described for the determination of caffeine in pharmaceutical preparations. A Spherisorb octadecylsilane ODS-2 C18 analytical column and spectrophotometric detection at 273 nm were used. The chromatographic behaviour of caffeine with different micellar eluents containing sodium dodecyl sulphate (SDS) is described. The determination of caffeine in pharmaceutical preparations was performed by use of a mobile phase containing 0.05 M sodium dodecylsulphate (SDS) and 1.5% propanol at pH7. At a 6.0 μg mL−1 concentration level the peak area and peak height repeatability were 2.6 and 2.4%, respectively. The application of the proposed method to the analysis of five pharmaceutic…
