Combination Treatment with Imatinib and Mitoxantrone/Etoposide Is a Suitable Preparative Regimen before Allogeneic Transplantation in Patients with M…
2005
Abstract In advanced BCR-ABL-positive leukemia, combination of chemotherapy with imatinib is expected to result in better reduction of leukemia cell load and may delay or offset clonal selection of resistant leukemia cells, thus improving the survival. We carried out a prospective phase I/II combination trial for patients (pts) with myeloid blast crisis of chronic myelogenous leukemia (CML). Pts were treated with imatinib+mitoxantrone/etoposide in four cohorts starting from mitoxantrone 10mg/m2/d and etoposide 100 mg/m2/d for 2 or 3 consecutive days and start of imatinib 600mg/d from day 15 (coh. 1 and 2) or from day 1 (coh. 3 and 4, respectively). After hematologic reconstitution following…
D1 receptors play a major role in the dopamine modulation of mouse ileum contractility
2010
Since the role of dopamine in the bowel motility is far from being clear, our aim was to analyse pharmacologically the effects of dopamine on mouse ileum contractility. Contractile activity of mouse ileum was examined in vitro as changes in isometric tension. Dopamine caused a concentration-dependent reduction of the spontaneous contraction amplitude of ileal muscle up to their complete disappearance. SCH-23390, D1 receptor antagonist, which per se increased basal tone and amplitude of spontaneous contractions, antagonized the responses to dopamine, whilst sulpiride or domperidone, D2 receptor antagonists, were without effects. The application of both D1 and D2 antagonists had additive effe…
Effects of Different Opioid Receptor Antagonists on the Electrically-Evoked Release of Endogenous Dopamine from the Isolated Neural Lobe of the Rat P…
2009
Abstract Isolated neural lobes of the rat pituitary gland were incubated in Krebs-HEPES solution which contained the dopamine uptake inhibitor GBR 12921 and in some experiments additionally pargyline. The release of endogenous dopamine evoked by electrical stimulation of the pituitary stalk was determined by high-performance liquid chromatography with electrochemical detection. (+/-)- Naloxone increased the evoked dopamine release maximally by 440% (EC(50) 209 nM). The (+)-enantiomer of naloxone (up to 10 muM) did not affect the release of dopamine. The preferential kappa-opioid receptor antagonist MR 2266 increased the evoked dopamine release maximally by 135% (EC(50) 7 nM). MR 2267, the i…
Dimensional Classification as an Instrument for Biological Research in Endogenous Depression
1986
Biological psychiatry needs highly reliable classifications capable of supplying research with homogeneous groups of patients. Operational diagnoses (OPD abbreviated) have been introduced to serve this aim. At present, research in endogenous depression can choose among more than ten different operational diagnoses, all purporting to be valid for diagnosing endogenous depression. Eight of these operational diagnoses are listed in Table 1.
Comprehensive pharmacokinetic model of insulin Glargine and other insulin formulations.
2005
In this paper, a comprehensive pharmacokinetic model for different insulin formulations including insulin Glargine is developed based on the model proposed by Trajanoski et al. (1993). Current models show limitations for insulin Glargine due to the appearance of an uncharacteristic peak in the concentration-time evolution of plasma insulin that does not coincide with real experimental data. This important limitation has been solved in this paper by introducing a new virtual insulin state called the bound state, in addition to the dimeric and hexameric ones. Trying to describe the retarded action of insulin Glargine, the modeling idea behind this approach is that immediately after the subcut…
Low-Dose Aclacinomycin and Intermediate-Dose Cytosine Arabinoside in Relapsed and Refractory Acute Myelogenous Leukemia
1990
Nineteen patients with relapsed or refractory acute myelogenous leukemia were treated with escalating doses of aclacinomycin (ACLA 20–30 mg/m2 daily for 5 days) and intermediate-dose cytosine arabinoside (Ara-C 1 g/m2 twice daily for 4 days). Most patients had received previous therapy with high- or intermediate-dose Ara-C plus mitoxantrone (HAM, IAM) and TAD (6-thioguanine, standard-dose cytosine arabinoside, and daunorubicin). Four patients had had repeated relapses and another three were treated for primary treatment failure following induction with HAM or I AM.
„Eine Medizin der menschlichen Beziehungen” revisited - Aktuelle neurobiologische und psychosomatische Entwicklungen
2007
In his programmatic paper published 1989 in this journal, Herbert Weiner held the view that psychosomatic medicine has become a medicine of human relations. The aim of this review is TO reflect if current scientific evidence supports his view. Evidence from animal studies suggests that early infant-mother separation or neglect not only has a lasting influence on attachment behaviour, but also on brain development and the ability for stress regulation mediated by environmental as well as genetic factors. Neuronal networks processing affective components of physical pain play a role in signalling painful emotional experiences due to social isolation and separation. A consistent finding across…
Combining Three Different Pretransplantation Scores Improves Predictive Value in Patients after Haploidentical Stem Cell Transplantation with Thiotep…
2021
ABSTRACT One hundred and sixty-one patients underwent haploidentical stem cell transplantation (haploSCT) with thiotepa, busulfan, and fludarabine conditioning followed by post-transplantation cyclophosphamide (PTCy) (on days +3 and +4) and tacrolimus as graft-versus-host disease prophylaxis. Forty-two percent of patients had a high or very high revised Disease Risk Index (rDRI), 55% had an European Society for Blood and Marrow Transplantation risk score (EBMT-RS) ≥4, and 36% had an age-adjusted Hematopoietic Cell Transplant Comorbidity Index (HCT-CI-age) score ≥3. Each of these was considered an unfavorable score. Using the pretransplantation unfavorable scores that had an independent impa…
Dopaminergic modulation of evoked vasopressin release from the isolated neurohypophysis of the rat
1982
1. Neurointermediate lobes of rat pituitaries were incubated in Locke or Krebs solution, and the vasopressin released into the medium was assayed on the blood pressure of the pithed rat or by a radioimmunological procedure. Release of vasopressin over resting levels was evoked either by incubation with 60 mM KCl (high K) solution or by electrical stimulation of the pituitary stalk. Two different kinds of electrical stimulation were carried out. Procedure A (1 ms, 10 Hz, 5 times for 1 min within 10 min) induced a vasopressin overflow which was greatly calcium-dependent but only insignificantly sensitive to tetrodotoxin (TTX). Procedure B (0.2 ms, 15 Hz, 10 s trains with 10 s intervals for 10…
Differential effects of potassium channel blockers on neurohypophysial release of oxytocin and vasopressin. Evidence for frequency-dependent interact…
1988
Isolated rat neurohypophyses were fixed by their stalks to a platinum wire electrode and superfused with Krebs-HEPES solution. Vasopressin and oxytocin released into the medium were determined by specific radioimmunoassays. Hormone secretion was increased by electrical stimulation of the pituitary stalk at different frequencies. The effects of several potassium channel blockers, tetraethylammonium (TEA) ions, 4-aminopyridine (4-AP) and 3,4-diaminopyridine (3,4-DAP) were tested. The release of vasopressin and oxytocin evoked by electrical stimulation with 900 pulses at 15 Hz (about 900 and 1,000 μU, respectively) was about 10 times higher than that evoked by 900 pulses at 3 Hz. Both 10 and 3…
