Four and One-Half-Year Follow-up of the Effectiveness of Diphtheria-Tetanus Toxoids-Acellular Pertussis/Haemophilus influenzae Type b and Diphtheria-…
2004
Background: Recently an increase in the number of invasive Haemophilus influenzae type b (Hib) cases was observed in the United Kingdom, which coincided with a temporary change from diphtheria-tetanus toxoids-wild-type pertussis to diphtheria-tetanus toxoids-acellular pertussis (DTaP) Hib vaccines. A study in Germany based on approximately 2 years of follow-up, estimated vaccine effectiveness (VE) of DTaP/Hib and DTaP-inactivated poliovirus/Hib combination vaccines against invasive Hib disease to be high. Objectives: To assess VE of DTaP-containing Hib vaccines against Hib in Germany with the use of extended follow-up of case surveillance and vaccine uptake. Subjects and Methods: Cases with…
Immunogenicity and reactogenicity of a bicomponent and a tricomponent acellular pertussis-diphtheria-tetanus (DTaP) vaccine in primary immunization a…
1996
Abstract Objectives: To compare the immunogenicities and reactogenicities of bicomponent (B) (pertussis toxoid, filamentous hemagglutinin) and tricomponent (T) (pertussis toxoid, filamentous hemagglutinin, pertactin) acellular pertussis vaccines when coadministered with diphtheria and tetanus toxoids in primary (3, 4, and 5 mo) and booster (15–19 mo) vaccinations. Design and Methods: A randomized, double-blind study involving 175 children aged 12 to 18 weeks. Reactogenicity was based on diary cards, immunogenicity assessed by ELISA measurements of serum IgG antibodies. Results: There were no clinically relevant differences in local (B = 34.5; T=31.3%) and general (B = 43.9; T=41.8%) reactog…
1,2,4-Oxadiazole Topsentin Analogs with Antiproliferative Activity against Pancreatic Cancer Cells, Targeting GSK3β Kinase.
2021
A new series of topsentin analogs, in which the central imidazole ring of the natural lead was replaced by a 1,2,4- oxadiazole moiety, was efficiently synthesized. All derivatives were pre-screened for antiproliferative activity against the National Cancer Institute (NCI-60) cell lines panel. The five most potent compounds were further investigated in various pancreatic ductal adenocarcinoma (PDAC) cell lines, including SUIT-2, Capan-1, and Panc-1 cells, eliciting EC50 values in the micromolar and sub-micromolar range, associated with significant reduction of cell migration. These remarkable results might be explained by the effects of these new topsentin analogues on epithelial-to-mesenchy…
Predictive Factors for Changes in Quality of Life after Steroid Treatment for Active Moderate-to-Severe Graves' Orbitopathy: A Prospective Trial.
2019
<b><i>Objectives:</i></b> To investigate the predictive factors for changes in the quality of life (GO-QoL) of patients with Graves’ orbitopathy (GO) prior to and after specific treatment. <b><i>Methods:</i></b> A prospective follow-up study was conducted at an academic tertiary referral orbital center with a joint thyroid-eye clinic on 100 consecutive patients with GO. Before and after the standard 12-week course of weekly intravenous methylprednisolone (cumulative dose 4.5 g), the GO-QoL questionnaire provided by the European Group on Graves’ Orbitopathy (EUGOGO) was completed. Endocrine and ophthalmic assessments were performed at each visi…
Correlation of Pharmacological Properties of a Group of Hypolipaemic Drugs by Molecular Topology
1996
Abstract This investigation was undertaken to test the ability of the molecular connectivity model to predict the percentage of plasma protein binding, the percentage of total cholesterol reduction and oral LD50 in rats of a group of hypolipaemic drugs using multi-variable regression equations with multiple correlation coefficients, standard error of estimate, degrees of freedom, F-Snedecor function values, Mallow's CP and Student's t-test as criteria of fit. Regression analyses showed that the molecular connectivity model predicts these properties. Corresponding stability (cross validation) studies were made on the selected prediction models which confirmed their goodness of fit. The resul…
Simulazione di un irradiatore gamma con codice Monte Carlo: valutazione della dose e verifica dei contributi strutturali
2015
Si è utilizzato il codice di calcolo Montecarlo MCNP4C per simulare sia le sorgenti che i materiali strutturali dell’irradiatore IGS3, al fine valutarne i loro contributi. Il numero di storie simulate è stato fissato in modo da ottenere un errore casuale abbastanza piccolo. Si sono utilizzati due scenari: uno in presenza del ripiano di appoggio dei campioni da irradiare ed uno senza. I punti dose sono stati posti a tre distanze dalle sorgenti e a tre quote rispetto al piano di appoggio. Negli stessi punti–dose sono state eseguite delle misure sperimentali utilizzando due coppie di sorgenti di radioattive. Sia le simulazioni che i punti sperimentali sono stati messi in relazione con i risult…
Investigation of committed radiation dose rate and relationships between alkaline metals concentrations in mushroom Xerocomus badius / Badanie wchłon…
2012
Abstract The fruiting bodies of fungi sprout from mycelium are capable of accumulating significant amounts of trace elements, both metals and metalloids. Content of these elements in fruiting bodies may exceed their concentration in the substrate where fungi develop. Among the elements the radioactive nuclides are also present. In this work health risk caused by increased radioactivity dose absorbed with Xerocomus badius bay bolete consumption was estimated. In analysis concentrations of radioactive isotopes 137Cs and 40K were taken into consideration. It was found that moderate ingestion of bay bolete does not create health risk due to increased radioactive substances intake. The amount of…
Stress-first single photon emission computed myocardial perfusion imaging
2016
Background. Myocardial perfusion imaging (MPI) with single photon emission tomography (SPET) is widely used in coronary artery disease evaluation. Recently major dosimetric concerns have arisen. The aim of this study was to evaluate if a pre-test scoring system could predict the results of stress SPET MPI, thus avoiding two radionuclide injections. Methods. All consecutive patients (n=309) undergoing SPET MPI during the first 6 months of 2014 constituted the study group. The scoring system is based on these characteristics: age >65 years (1 point), diabetes (2 points), typical chest pain (2 points), congestive heart failure (3 points), abnormal ECG (4 points), male gender (4 points), and…
Kelfiprim, a new sulpha-trimethoprim combination, versus cotrimoxazole, in the treatment of urinary tract infections: a multicentre, double-blind tri…
1982
A new combination of trimethoprim with a sulphonamide, named Kelfiprim, differs from cotrimoxazole in that: a) the sulpha drug is sulphamethopyrazine instead of sulphamethoxazole; b) the trimethoprim to sulpha ratio is 5:4 instead of 1:5;c) the presence of a long-acting sulphonamide allows the administration of a daily dose of one capsule, following an initial loading dose of two capsules; d) a reduced amount of trimethoprim is given, as compared to cotrimoxazole, without any decrease of efficacy. Kelfiprim [KP] was compared to contrimoxazole [Co] in a multicentre double blind trial. Sixty four patients suffering from acute and chronic infections of the upper and lower urinary tract entered…
A transcranial magnetic stimulation study evaluating methylprednisolone treatment in multiple sclerosis
2002
Objective - To investigate the efficacy of two different high doses of intravenous methylprednisolone (IVMP) during Multiple Sclerosis (MS) relapses. Background - Transcranial Magnetic Stimulation (TMS) is the most sensitive neurophysiological ascertainment to quantify motor disability, to follow the recovery from an MS relapse, and to detect the response to treatment. Design and method - Twenty-four clinically definite relapsing - remitting MS patients presenting a relapse were randomly assigned to a treatment for 5 days with IVMP 1 or 2 g/day. The response to treatment of each patient was evaluated through Expanded Disability Status Scale (EDSS), Medical Research Council (MRC) score, and …
