Three de novo losses and one insertion within a pericentric inversion of chromosome 6 in a patient with complete absence of expressive speech and red…
2008
A 32-year-old female patient, observed for 30 years because of a distinctive phenotype consisting of a dysmorphic face non-progressive deficit of motor control, lack of speech development, reduced sensitivity to pain, with a known, complex interstitial deletion 6q14 within a de novo pericentric inversion 6p11.2;q15, was re-examined at the molecular level. Applying the Infinium HumanHap300 BeadChip array and BAC-based FISH we found two new non-contiguous microdeletions in addition to the one detected previously by high resolution G-band analysis. A 360 kb loss in band 6p12.3, containing the genes RHAG, CRISP1, 2, and 3, and PGK2, a 1.15 Mb loss in 6p12.2-p12.1, containing the genes PKHD1, IL…
Rapid High Efficiency Sensitization of CD8+ T Cells to Tumor Antigens by Dendritic Cells Leads to Enhanced Functional Avidity and Direct Tumor Recogn…
2003
Abstract Myeloid-origin dendritic cells (DCs) can develop into IL-12-secreting DC1 or non-IL-12-secreting DC2 depending on signals received during maturation. Through rapid culture techniques that prepared either mature, CD83+ DC1 or DC2 from CD14+ monocytes in only 2 days followed by a single 6–7 day DC-T cell coculture, we sensitized normal donor CD8+ T cells to tumor Ags (HER-2/neu, MART-1, and gp100) such that peptide Ag-specific lymphocytes constituted up to 16% of the total CD8+ population. Both DC1 and DC2 could sensitize CD8+ T cells that recognized peptide-pulsed target cells. However, with DC2, a general decoupling was observed between recognition of peptide-pulsed T2 target cells…
Upregulation of the netrin receptor (DCC) gene during activation of b lymphocytes and modulation by interleukins.
2001
The DCC (deleted in colon cancer) gene has a brain restricted high expression pattern. It encodes a transmembrane protein of the immunoglobulin superfamily identified as the netrin-1 receptor. It might be a member of the so called "brain-lymphoid" molecules, which control key cell surface events. To test this hypothesis we have assessed the DCC mRNA level in human normal and malignant myeloid and lymphoid cells. A high mRNA content has been observed only in mature B cells at the secreting or presecreting stage. Expression of DCC was also assessed in the anti-CD40 model of immunopoiesis. Activation of purified tonsillar B cells by anti-CD 40 antibody strongly increased the DCC mRNA level and…
The appropriateness of colonoscopies at a teaching hospital: magnitude, associated factors, and comparison of EPAGE and EPAGE-II criteria.
2011
Background The growing demand for colonoscopies and inappropriate colonoscopies have become a significant problem for health care. Objectives To assess the appropriateness of colonoscopies and to analyze the association with some clinical and organizational factors. To compare the results of the European Panel of Appropriateness of Gastrointestinal Endoscopy (EPAGE) and the EPAGE-II criteria. Design Cross-sectional study. Setting Endoscopy unit of a teaching hospital in Spain. Patients Patients referred for colonoscopy, excluding urgent, therapeutic indications, and poor cleansing. Main Outcome Measurements Appropriateness of colonoscopies according to the EPAGE criteria. Results From 749 c…
Cells expressing markers of immature neurons in the amygdala of adult humans
2012
The polysialylated form of the neuronal cell adhesion molecule (PSA-NCAM) is expressed by immature neurons in the amygdala of adult mammals, including non-human primates. In a recent report we have also described the presence of PSA-NCAM-expressing cells in the amygdala of adult humans. Although many of these cells have been classified as mature interneurons, some of them lacked mature neuronal markers, suggesting the presence of immature neurons. We have studied, using immunohistochemistry, the existence and distribution of these immature neurons using post mortem material. We have also analysed the presence of proliferating cells and the association between immature neurons and specialise…
Genome-wide Association Study of Alcohol Dependence
2009
Context Alcohol dependence is a serious and common public health problem. It is well established that genetic factors play a major role in the development of this disorder. Identification of genes that contribute to alcohol dependence will improve our understanding of the mechanisms that underlie this disorder. Objective To identify susceptibility genes for alcohol dependence through a genome-wide association study (GWAS) and a follow-up study in a population of German male inpatients with an early age at onset. Design The GWAS tested 524 396 single-nucleotide polymorphisms (SNPs). All SNPs with P −4 were subjected to the follow-up study. In addition, nominally significant SNPs from genes t…
Non-adherence to psychotropic medication assessed by plasma level in newly admitted psychiatric patients: Prevalence before acute admission.
2019
Aims Non-adherence or partial adherence to psychotropic medication is found in 18-70% of patients. Many previously used methods for the assessment of adherence (e.g. questionnaires, pill counts, and electronic systems), however, might underreport actual rates of non-adherence to medication. The aim of this study was to quantify adherence using plasma level. Methods We conducted a 6-week prospective study of all consecutive admitted patients at the Paracelsus Medical University of Salzburg, Clinics of Psychiatry and Psychotherapy, who had been treated with antipsychotics/antidepressants prior to admission (pre-medication dosage in 161 of 233). Plasma drug levels were determined and compared …
ICAM-1 and α3β1 expression by bronchial epithelial cells and theirin vitromodulation by inflammatory and anti-inflammatory mediators
2000
Background: Adhesion molecules are involved in inflammatory and repair processes of the bronchial epithelium. ICAM-1 is mainly involved in inflammatory reactions, whereas integrins, such as α3β1, are mainly involved in repair processes. Methods: Using bronchial biopsies from 10 asthmatics and eight controls, we first evaluated by immunohistochemistry expression of α3β1 and ICAM-1 in intact and damaged epithelium. Then, using the human pulmonary epithelial cell line WI-26 VA, we studied, by flow-cytometry, the modulation of ICAM-1 and α3β1 expression, and, by ELISA, the release of fibronectin by proinflammatory cytokines, such as IL-5, and anti-inflammatory cytokines, such as IL-4, TGF-β, an…
Circulating, intercellular adhesion molecule-1 in patients with hepatocellular carcinoma
1997
Intercellular adhesion molecule-1 (ICAM-1) is thought to play an important role in cellular immunological reactions. Expression can be induced by inflammatory cytokines in a wide variety of cells, including hepatocytes.To compare the behaviour of ICAM-1 in liver diseases.We assayed serum ICAM-1 (sICAM-1) in patients with hepatocellular carcinoma-associated liver cirrhosis, and compared them with a group of cirrhotic patients and controls. sICAM-1 values were also correlated with some biochemical parameters of liver function. Moreover, immunohistochemical localization of ICAM-1 was performed on liver tissue sections of patients with hepatocellular carcinoma, liver cirrhosis and a sample of n…
Treatment of chronic hepatitis B in sub-Saharan Africa: 1-year results of a pilot program in Ethiopia
2018
Background The World Health Organization has set an ambitious goal of eliminating viral hepatitis as a major public health threat by 2030. However, in sub-Saharan Africa, antiviral treatment of chronic hepatitis B (CHB) is virtually unavailable. Herein, we present the 1-year results of a pilot CHB treatment program in Ethiopia. Methods At a public hospital in Addis Ababa, CHB patients were treated with tenofovir disoproxil fumarate based on simplified eligibility criteria. Baseline assessment included liver function tests, viral markers, and transient elastography (Fibroscan). Changes in laboratory markers were analyzed using Wilcoxon signed-rank tests. Adherence to therapy was measured by …
