Current results on the use of imatinib mesylate in patients with relapsed philadelphia chromosome positive leukemia after allogeneic or syngeneic hem…
2003
Here, we describe a patient diagnosed with chronic myelogenous leukemia who relapsed after matched unrelated donor SCT. The patient was treated with imatinib mesylate and donor lymphocyte infusions, and achieved a complete molecular remission. Additionally, safety and efficacy of imatinib mesylate in a total of 134 patients from 8 centers who underwent allogeneic or syngeneic stem cell transplantation (SCT) and had a relapse of Philadelphia chromosome positive leukemia was reviewed. Data was compiled from abstracts accepted as oral or poster presentations at the ASH (American Society of Hematology) 2001 and EBMT (European Group for Blood and Marrow Transplantation) 2001 & 2002 meetings and …
Long-Term Human CD34+ Stem Cell-Engrafted Nonobese Diabetic/SCID/IL-2Rγnull Mice Show Impaired CD8+ T Cell Maintenance and a Functional Arrest of Imm…
2010
Abstract Allogeneic hematopoietic stem cell transplantation represents the most effective form of immunotherapy for chemorefractory diseases. However, animal models have been missing that allow evaluation of donor-patient–specific graft-versus-leukemia effects. Thus, we sought to establish a patient-tailored humanized mouse model that would result in long-term engraftment of various lymphocytic lineages and would serve as a donor-specific surrogate. Following transfer of donor-derived peripheral blood stem cells into NOD/SCID/IL-2Rγnull (NSG) mice with supplementation of human IL-7, we could demonstrate robust engraftment and multilineage differentiation comparable to earlier studies using …
Olfactory Event-Related Potentials Reflect Individual Differences in Odor Valence Perception
2006
Investigating the neural substrates of perceived quality in olfaction using different odorants is intrinsically difficult. By utilizing individual differences in perceived quality of the odor of androstenone, we obtained a continuum of individual differences in rated valence of the same stimulus allowing investigations of its manifestation in the olfactory event-related potentials (ERPs). In an initial group consisting of 43 individuals that were screened for their verbal descriptors and sensitivity for the odor of androstenone, 22 normosmic volunteers were chosen forming 2 distinct groups with regard to verbal labels (‘‘body odor'' and ‘‘nonbody odor'') for androstenone while maintaining c…
Echocardiography in diagnosis of aortic dissection.
1989
In a multicentre study the accuracy of echocardiography was measured in 164 consecutive patients with suspected aortic dissection. The diagnosis was subsequently proven (82 patients) on the basis of transthoracic and transoesophageal echocardiography and additional diagnostic procedures, including computed tomography (CT), aortic angiography, and surgery and/or necropsy. The sensitivity and specificity of echocardiography were 99% and 98%, respectively, with positive and negative predictive values of 98% and 99%. For CT sensitivity was 83%, specificity 100%, and positive and negative predictive values 100% and 86%, respectively. For aortography sensitivity and specificity were 88% and 94%, …
Lens-vault analysis and its correlation with other biometric parameters using swept-source OCT
2021
Purpose To measure lens vault (LV) and to assess its correlation with various ocular parameters in healthy eyes, using for all measurements the same high-resolution swept-source optical coherence tomographer (SS-OCT). Methods We prospectively recruited 67 Caucasian healthy patients whose mean age was 41.9 ± 12.4 years; only their right eye was included in the study. Data were all recorded with the ANTERION SS-OCT and comprised, for each patient, 5 consecutive measurements of LV, anterior chamber depth (ACD), lens thickness (LT), axial length (AL), white-to-white (WTW) distance, central corneal thickness (CCT), anterior chamber volume (ACV) and spur-to-spur (STS) distance. Results Mean LV wa…
Is Propionibacterium acnes related to disc degeneration in adults? A systematic review.
2016
Background The aim of this paper was to systematically review the evidence linking Propionibacterium acnes (P. acnes) with the development of symptomatic degenerative disc disease. Evidence acquisition Data were obtained from MEDLINE from their inception to October 2015. Two authors independently conducted the searches, extracted data and completed methodological quality assessments. Articles were included if they investigated the presence of P. acnes in symptomatic degenerative disc disease through intra-operative cultural examination. The methodological quality of the studies was evaluated using the Newcastle-Ottawa Scale. Evidence synthesis Overall 641 articles were retrieved with 9 cros…
The negative predictive value of cervical interleukin-6 for the risk assessment of preterm birth.
2013
To determine the potential clinical use of cervical interleukin-6 (IL-6) as a negative predictor of preterm birth in symptomatic women.Observational prospective study carried out in a tertiary hospital.We studied 100 singleton pregnant women with threatened preterm delivery and intact membranes, between 24 and 34 weeks, recruited during the period 2006-2008. A cervical swab for IL-6 detection was taken and a transvaginal ultrasound scan was performed for measuring the cervical length.Five women delivered within 2 d and six women within 7 d. A high cervical IL-6 concentration was found in these women. The area under the ROC curve for cervical IL-6 was 0.97 for deliveries within 2 d after the…
The use of computer-assisted video image analysis for the quantification of CD8+ T lymphocytes producing tumor necrosis factor alpha spots in respons…
1997
Enzyme-linked immunospot (ELISPOT) analysis is a sensitive technique for the detection and quantification of single T lymphocytes forming cytokine spots after antigen contact in vitro. Herein computer-assisted video image analysis (CVIA) was applied to automatically determine the number and size of tumor necrosis factor alpha (TNF-alpha) spots formed by single blood-derived CD8+ T cells after contact with peptide-loaded target cells. With CVIA and TNF-alpha ELISPOT analysis we quantified CD8+ T cells responsive to HLA-A2.1-binding tyrosinase and influenza matrix peptides in healthy donors. We followed the course of the virus-specific T cell response in two HLA-A2-positive patients with reac…
Maternal Parenting and Preschoolers’ Psychosocial Adjustment: A Longitudinal Study
2022
Previous research reported that positive parenting and parenting stress might impact children’s psychosocial adjustment. The current longitudinal study aimed at evaluating the associations over time between mothers’ positive parenting, their parenting stress, and their preschoolers’ social–emotional competence and emotional–behavioral difficulties. Participants were 53 Italian mothers, aged between 24 and 47 years (M = 35.30, SD = 5.28) at T0, and their children (females = 51%), aged between 3 and 6 years (M = 4.48, SD = 0.84) at T0. Mothers completed self-report scales at 2 time points (with a 2-year lag). An autoregressive cross-lagged model was tested that h…
Rasgos esquileos en la caracterización de algunos personajes sofocleos
2008
Jose.V.Banuls@uv.es Carmen.Morenilla@uv.es Frente a la ignorancia en sus diversas formas como fuente del error trágico que caracteriza a los héroes de Sófocles, los de Esquilo son conscientes de lo que hacen, pero su grado de consciencia se halla alterado por una fuerza negativa que surge de su propio linaje. Encontramos estos rasgos esquileos, pero positivados, en Antígona. In contrast with ignorance as the source of the tragic error which characterizes the heroes of Sophocles, the heroes of Aeschylus are fully aware of their actions. However, the degree of their awareness is altered by a negative force which emerges from their lineage. These Aeschylean features are positively presented in…
