The effect of Dextransulfate 500 on the pathogenesis of herpes simplex virus infections in weanling mice
1978
Intraperitoneal (i.p.) injection of Dextran Sulfate (D.S.) 500 during a limited period of time influences the course of herpes simplex-virus-infections. D.S.500 was found to reduce the resistance of mice for some herpes simplex-virus strains (Len, L3-2s, Haase) if given between 16 hours before and 2 hours after i.p. infection. The decrease of resistance could be correlated with an increase of the virus content of liver, spleen, brain and spinal cord. Injection of herpes simplex-virus-specific immune serum counteracted the effect of D.S.500 on the course of infections. Conversely, D.S.500 increased the resistance of mice to another group of herpes simplex-viruses (strains D-316, Thea, DD), i…
Localization of the bradykinin B2 receptor in uterus, bladder and Madin-Darby canine kidney cells
1997
Kinins are biologically active peptides that act through specific receptors, B1 and B2. Here we describe the localization of the bradykinin B2 receptor in Madin-Darby canine kidney cells and in the uterus and urinary bladder of rat or human origin. We discuss the suitability of anti-peptide antibodies to assess the tissue distribution of bradykinin B2 receptors.
OP29 Tofacitinib in ulcerative colitis: Real-world evidence from Eneida Registry
2020
Abstract Background Our aim was to evaluate the effectiveness and safety of tofacitinib in ulcerative colitis (UC) in real life. Methods Patients from the prospectively maintained ENEIDA registry treated with tofacitinib due to active UC were included. Clinical activity and effectiveness were defined based on Partial Mayo Score (PMS). The short-term response was assessed at week 4, 8 and 16. The last-observation-carried-forward method was used in patients that stopped tofacitinib before the time-points for clinical assessment. Variables associated with short-term remission at week 8 were identified by logistic regression analysis. The cumulative retention rate and the cumulative incidence o…
Induction of gamma-globin gene transcription by hydroxycarbamide in primary erythroid cell cultures from Lepore patients.
2008
Increased expression of fetal haemoglobin (HbF) may ameliorate the clinical course of beta-thalassemia and sickle cell disease. Some pharmacological agents, such as hydroxycarbamide (HC), can increase fetal haemoglobin synthesis during adult life. Cellular selection and/or molecular mechanisms have been proposed to account for this increase. To explore the mechanism of action of HC we focused on homozygous Hb-Lepore patients that presented with high fetal haemoglobin levels and were good responders to HC treatment "in vivo". We performed primary erythroid cultures from peripheral blood of four homozygous Lepore patients. The increase in HBG (gamma-globin) transcription levels and HbF conten…
Regulation of PTHrP and PTH/PTHrP receptor by extracellular Ca2+ concentration and hormones in the breast cancer cell line 8701-BC.
2000
AbstractIt was previously reported that 8701-BC breast tumour cells express the gene for parathyroid hormonerelated peptide (PTHrP) and PTH/PTHrP receptor (PTHrPR) and release immunoreactive PTHrP (iPTHrP) into the extracellular medium. Since the regulation of PTHrP and PTHrPR by breast cancer cells has been poorly investigated so far, we have chosen the 8701- BC cell line as a model system to investigate whether alterations in the extracellular Ca[2+] concentration ([Ca[2+]]) and treatment with some wellknown differentiation agents for breast cells, such as dimethyl sulfoxide, hydrocortisone, progesterone, prolactin, alltrans retinoic acid and transforming growth factorβ1 might (i) modulat…
Differentialdiagnose Berylliose/Sarkoidose bei einem Zahntechniker
2008
History and clinical findings Sarcoidosis was diagnosed in a dental technician when he was aged 21 years. Two years later prednisolone treatment was started and continued for 14 years because of nonproductive cough with progressive reduction in vital capacity and CO transfer capacity. Subsequently the risk of exposure to beryllium-containing dust in dental laboratories became known. In his case exposure had started before sarcoidosis had been diagnosed and had continued for 16 years. Changes typical of sarcoidosis (unproductive cough and dyspnoea; bihilar lymphadenopathy and reticulonodular marking in the chest radiogram) were now present, at the age of 40 years. Investigations Vital and di…
External evaluation of population pharmacokinetic models of vancomycin in neonates: the transferability of published models to different clinical set…
2013
Vancomycin is one of the most evaluated antibiotics in neonates using modeling and simulation approaches. However no clear consensus on optimal dosing has been achieved. The objective of the present study was to perform an external evaluation of published models, in order to test their predictive performances in an independent dataset and to identify the possible study-related factors influencing the transferability of pharmacokinetic models to different clinical settings. Published neonatal vancomycin pharmacokinetic models were screened from the literature. The predictive performance of 6 models was evaluated using an independent dataset (112 concentrations from 78 neonates). The evaluati…
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…
Lung Injury Is a Predictor of Cerebral Hypoxia and Mortality in Traumatic Brain Injury
2020
Background: A major contributor to unfavorable outcome after traumatic brain injury (TBI) is secondary brain injury. Low brain tissue oxygen tension (PbtO2) has shown to be an independent predictor of unfavorable outcome. Although PbtO2 provides clinicians with an understanding of the ischemic and non-ischemic derangements of brain physiology, its value does not take into consideration systemic oxygenation that can influence patients' outcomes. This study analyses brain and systemic oxygenation and a number of related indices in TBI patients: PbtO2, partial arterial oxygenation pressure (PaO2), PbtO2/PaO2, ratio of PbtO2 to fraction of inspired oxygen (FiO2), and PaO2/FiO2. The primary aim …
