Screening of subtelomeric rearrangements in autistic disorder: identification of a partial trisomy of 13q34 in a patient bearing a 13q;21p translocat…
2006
Within the framework of a FISH screening protocol to detect cryptic subtelomeric rearrangements in autistic disorder (AD), a patient bearing three copies of the subtelomeric portion of the q arm of chromosome 13 has been identified. Beside AD, the patient also has severe mental retardation and displays several dysmorphic features. Further FISH analyses revealed that the trisomy was caused by the translocation of a 13q subtelomeric fragment to the acrocentric tip of one chromosome 21 [46,XY.ish der(21) t(13;21) (q34;p13)(D13S1825+)]. Gene dosage experiments carried out with three multiallelic polymorphisms of the subtelomeric region of chromosome 13q showed that the putative length of the tr…
Effects of a plant-based fatty acid supplement and a powdered fruit, vegetable and berry juice concentrate on omega-3-indices and serum micronutrient…
2020
The major aim of this controlled, randomised, open-labelled, parallel-grouped, clinical trial was to investigate whether supplementation with different dosages of omega-3 fatty acids (0.5 g/d and 1 g/d) from a plant-based fatty acid supplement affected omega-3-indices (O3I) in well-nourished, healthy people. In addition, the combined ingestion of the plant-based fatty acid supplement, together with an encapsulated fruit, vegetable and berry (FVB) juice powder concentrate, was applied in order to observe the absorption of certain micronutrients and to examine some aspects related to the safe consumption of the products. The data demonstrate that the intake of only 0.5 g/day of omega-3 fatty …
Justification of Biowaiver for Carbamazepine, a Low Soluble High Permeable Compound, in Solid Dosage Forms Based on IVIVC and Gastrointestinal Simula…
2009
The aim of the present study was to use gastrointestinal simulation technology and in vitro-in vivo correlation (IVIVC) as tools to investigate a possible extension of biowaiver criteria to BCS class II drugs using carbamazepine (CBZ) as a candidate compound. Gastrointestinal simulation based on the advanced compartmental absorption and transit model implemented in GastroPlus was used. Actual in vitro and in vivo data generated in CBZ bioequivalence studies were used for correlation purposes. The simulated plasma profile, based on the CBZ physicochemical and pharmacokinetic properties, was almost identical with that observed in vivo. Parameter sensitivity analysis (PSA) indicated that the p…
Treatment of Ulcerative Colitis with Olsalazine and Sulphasalazine: Efficacy and Side-Effects
1988
The effects of olsalazine were studied mainly in patients with ulcerative colitis who were intolerant to sulphasalazine, and for relapse prevention. A crossover design with sulphasalazine, 3 g/day, and olsalazine, 1.5 g/day, was applied to compare the side-effects of each drug and to evaluate their therapeutic efficacy. A total of 41 patients with mild or moderately severe left-sided colitis or proctitis were assigned to a randomized treatment schedule. Olsalazine and sulphasalazine were similar in their therapeutic efficacy. Twelve patients complained of adverse effects while on sulphasalazine and 4 patients during olsalazine treatment (p less than 0.05). It is concluded that olsalazine is…
Assessment of modifications in thickness, curvatures, and volume upon the cornea caused by disposable soft contact lens wear.
2015
Purpose To assess the effect of different disposable soft contact lenses on several corneal parameters–-thickness, anterior and posterior curvature, and volume–-by means of a Scheimpflug imaging-based device (Pentacam HR). Diurnal variations of these parameters were taken into account. Methods Twenty-one young, healthy subjects wore 4 different types of daily disposable soft contact lenses on 4 different days: Dailies AquaComfort Plus, SofLens, Dailies Total1, and Acuvue TruEye. The lenses had different material and water content. Pachymetry and curvature maps and corneal volume values were obtained using the Pentacam HR twice a day: one before putting the lens on and one after an 8-hour pe…

1. Am J Gastroenterol. 2005 Dec;100(12):2730-6. Intestinal permeability and genetic determinants in patients, first-degree relatives, and controls in a high-incidence area of Crohn's disease in Southern Italy. Fries W, Renda MC, Lo Presti MA, Raso A, Orlando A, Oliva L, Giofré MR, Maggio A, Mattaliano A, Macaluso A, Cottone M. Dipartimento di Medicina Interna e Terapia Medica, Università di Messina, Messina, Italy. OBJECTIVE: A defect of gastrointestinal barrier function is considered to represent an important step in the pathogenesis of Crohn's disease (CD) but the mechanisms leading to an increased intestinal permeability (IP) are poorly understood. Since IP is influenced by pro-inflammat…
Estimated radiation exposure of German commercial airline cabin crew in the years 1960-2003 modeled using dose registry data for 2004-2015.
2016
Exposure to ionizing radiation of cosmic origin is an occupational risk factor in commercial aircrew. In a historic cohort of 26,774 German aircrew, radiation exposure was previously estimated only for cockpit crew using a job-exposure matrix (JEM). Here, a new method for retrospectively estimating cabin crew dose is developed. The German Federal Radiation Registry (SSR) documents individual monthly effective doses for all aircrew. SSR-provided doses on 12,941 aircrew from 2004 to 2015 were used to model cabin crew dose as a function of age, sex, job category, solar activity, and male pilots' dose; the mean annual effective dose was 2.25 mSv (range 0.01–6.39 mSv). In addition to an inverse …
Exposure to toxic agents alters organic elemental composition in human fingernails.
2008
Abstract Background and objective: The human fingernail plate is highly keratinized. The keratin structure is held together by disulfide bonds. The organic elements sulfur and nitrogen occur almost exclusively in amino acids of the nail plate. This study analyzed whether occupational exposure to harmful chemical agents alters the organic elemental composition in fingernails. Subjects and methods: Participants were 71 occupationally exposed workers (49 hairdressers, 22 painters) and 49 unexposed controls. Aspects of exposure were assessed by questionnaire. Nail clippings of index and little fingers were analyzed for sulfur (S), nitrogen (N), carbon (C), and hydrogen (H) contents, using an au…
Stromal myofibroblasts in oral leukoplakia and oral squamous cell carcinoma
2011
Objectives: Oral leukoplakia (OL) is the main potentially malignant disorder and oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral mucosa. Stromal myofibroblasts play an important role in tumor invasion and metastasis, due to its ability to modify the extracellular matrix. This study aimed to evaluate the presence of stromal myofibroblasts in OL and OSCC. Differences in the presence of myofibroblasts among OL with distinct grades of epithelial dysplasia as well as between histologically high- and low-invasive OSCC were also assessed. Study Design: A total of 30 OL and 41 OSCC from archival formalin-fixed, paraffin-embedded specimens were evaluated. 10 samples of …
Exposure to nitroaromatic explosives and health effects during disposal of military waste.
2003
To investigate the exposure to dinitrotoluene (DNT) and trinitrotoluene (TNT) and the resulting effects in workers which occur during the disposal of military waste.Eighty two employees from a mechanical plant in Germany were studied, of whom 51 were regularly exposed to ammunition containing TNT and DNT, 19 occasionally, and 12 not at all.Air analyses yielded maximum concentrations of 20 micro g/m(3) for 2,4-DNT and 3250 micro g/m(3) for 2,4,6-TNT, respectively. The maximum concentrations in the urine of workers regularly exposed amounted to 5.0 micro g/l of 2,4,6-TNT, 1464.0 micro g/l of 2-amino-4,6-dinitrotoluene, 6693.0 of micro g/l 4-amino-2,6-dinitrotoluene, 2.1 micro g/l of 2,4-DNT, …
