Regulation of cytokine expression by interferon-alpha in human bone marrow stromal cells: inhibition of hematopoietic growth factors and induction of…

1994

We investigated the effects of interferon-alpha (IFN-alpha) on the expression of cytokines by human bone marrow stromal cells. Production of granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte-CSF (G-CSF), and interleukin-1 beta (IL-1 beta) in stromal cell layers was induced by incubation with IL-1 alpha, tumor necrosis factor (TNF), or lipopolysaccharide (LPS). Addition of IFN-alpha to such stimulated cultures resulted in a strong downregulation of mRNA expression of GM-CSF and IL-1 beta. Similarly, the protein levels of GM- CSF and IL-1 beta were significantly reduced by IFN-alpha, whereas G- CSF production was only moderately inhibited. In contrast, IFN-alpha markedly …

2019

Objective: In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval training (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) and vagal heart rate variability (HRV). Methods: In the study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 female, 9 male) were subjected to orthostatic tests (HR and HRV recordings) each day during a 4-day baseline period, a 6-day overload microcycle, and a 4-day recovery period. Discipline-specific performance was assessed before and 1 and 4 days after training. Results: Following ST overload, supine HR, and vagal HRV (Ln RMSSD) were clearly increased and decreased (small …

Slow 0.1 Hz Breathing and Body Posture Induced Perturbations of RRI and Respiratory Signal Complexity and Cardiorespiratory Coupling

2020

Objective: We explored the physiological background of the non-linear operating mode of cardiorespiratory oscillators as the fundamental question of cardiorespiratory homeodynamics and as a prerequisite for the understanding of neurocardiovascular diseases. We investigated 20 healthy human subjects for changes using electrocardiac RR interval (RRI) and respiratory signal (Resp) Detrended Fluctuation Analysis (DFA, α1RRI, α2RRI, α1Resp, α2Resp), Multiple Scaling Entropy (MSERRI1−4, MSERRI5−10, MSEResp1−4, MSEResp5−10), spectral coherence (CohRRI−Resp), cross DFA (ρ1 and ρ2) and cross MSE (XMSE1−4 and XMSE5−10) indices in four physiological conditions: supine with spontaneous breathing, stand…

Chick embryo retina development in vitro: the effect of insulin.

1995

In this paper we study the development of chick embryo retina cultured in vitro and the effects exerted by insulin. Retinas were removed from 7-day embryos and cultured in serum- and hormone-free medium for 7 additional days. Under these conditions retinal cells survived and underwent cholinergic differentiation, as previously ascertained by Hausman et al. (Dev. Brain Res., 1991, 59: 31-37). However, a great retardation of development was noted compared to uncultured control, 14-day retina. In fact both wet weight and DNA and protein content increased much slower than in ovo and the tubulin content decreased below even the starting value. In addition, although after 7 days in culture retina…

Prevalence and Clinical Outcomes for Patients With ALK Gene Rearrangement in Europe: Preliminary Results from the European Thoracic Oncology Platform…

2012

ABSTRACT Background The prevalence of ALK gene rearrangement (ALK+) in European patients with non-small cell lung cancer (NSCLC) is unknown. The Lungscape project provides a platform to evaluate its expression and clinical significance in a large cohort of patients with resected NSCLC from 13 European sites in 11 countries. Methods Participating sites retrospectively identified cases of NSCLC with clinical demographic and outcome data, and available tissue for research according to predefined protocol criteria. Local ethical and regulatory approvals were adhered to. Clinical data were entered to a central, secure database. Accepted cases on the basis of completeness of clinical data were as…

Comparison of Allogeneic Stem Cell Transplantation for Transformed Acute Myeloid Leukemia Derived from MDS, CMML or MPN. a Report of the Chronic Mali…

2016

Abstract Introduction Myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN) and chronic myelomonocytic leukemia (CMML) can progress to acute myeloid leukemia (transformed AML). The aim of this EBMT registry study was to compare 3 year outcome in patients with transformed AMLwho received allogeneic stem cell transplantation according to the primary disease. Patients and Methods Within the European Society of Blood and Marrow Transplantation (EBMT) registry, we found 4214 patients (female: 39%, male: 61%) with transformed acute myeloid leukemia, who received allogeneic stem cell transplantation between 2000 and 2014. The primary disease was MDS (n=3541), CMML (n=251) or MPN (n=4…

Newborn infants and the moral significance of intellectual disabilities.

2001

This article presents moral philosophical arguments regarding life-saving medical treatment that may be more available to infants without disabilities than to infants with intellectual disabilities. The ideas are that children with disabilities are a burden to their families and to society and that a happy life may not be attainable for these children and their families. I argue that human well-being is not based merely on individual characteristics, but is a result of the individual's relation to other people. Further, children with disabilities are not inevitably a burden to their families or society. Accordingly, intellectual disability is not a sufficient reason for withholding life-sa…

Safety of agalsidase alfa in patients with Fabry disease under 7 years

2011

Aim:  To evaluate the safety and explore the efficacy of enzyme replacement therapy (ERT) for Fabry disease with agalsidase alfa in young children enrolled in the Fabry Outcome Survey (FOS). Methods:  This retrospective chart review identified eight children (mean age = 5.0 ± 1.6 [mean ± SD]) in FOS who began treatment with agalsidase alfa (0.2 mg/kg, i.v., every other week) when <7 years old. Vital signs and adverse events were monitored throughout the study period. Glomerular filtration rate (GFR) was estimated, and left ventricular mass indexed to height2.7 (LVMi) was assessed with echocardiography. Patients received 1.2–6.7 years of treatment (mean = 4.2 years). Results:  Infusion react…

Local Formula with Mucoadhesive Property: A Randomized Clinical Trial of a Therapeutic Agent for the Treatment of Oral Aphthous Ulcers

2020

Background Recurrent or occasional aphthous lesions represent a painful oral condition with high prevalence. Since the etiology is still unclear and most likely related to a dysfunction in the local immune system, several treatment strategies have been proposed, including systemic agents, local agents, and laser therapy, to reduce the pain and discomfort for the patient without acting on the causes. Materials and methods The purpose of the present randomized study was to assess the clinical efficacy of a new topical gel with mucoadhesive property to reduce the pain and the dimension of the aphthosis lesions. Fifty patients presenting at least one minor ulcer were randomized to a control gro…
