Doxepin and its metabolites in plasma and cerebrospinal fluid in depressed patients
1997
Little information exists on the concentrations of antidepressants and their metabolites in CSF. We measured plasma and CSF levels of trans-doxepin (trans-DOX) and DOX metabolites in 12 depressed patients treated with DOX (250 mg/day) for 6 days. Spinal taps and blood samples were taken on day 7, 10 h after drug administration. Trans-DOX, cis-desmethyldoxepin (cis-DM-DOX), trans-desmethyldoxepin (trans-DM-DOX) and di-desmethyldoxepin (DDM-DOX) were analyzed in CSF and plasma samples by HPLC with column-switching. Although DOX was given as a mixture of 85% trans-DOX and 15% of the pharmacologically more active cis-DOX, we found similar amounts of cis-DM-DOX and trans-DM-DOX in plasma (59.8 +…
Intracellular Cytokine Staining and Flow Cytometry: Considerations for Application in Clinical Trials of Novel Tuberculosis Vaccines.
2015
Intracellular cytokine staining combined with flow cytometry is one of a number of assays designed to assess T-cell immune responses. It has the specific advantage of enabling the simultaneous assessment of multiple phenotypic, differentiation and functional parameters pertaining to responding T-cells, most notably, the expression of multiple effector cytokines. These attributes make the technique particularly suitable for the assessment of T-cell immune responses induced by novel tuberculosis vaccines in clinical trials. However, depending upon the particular nature of a given vaccine and trial setting, there are approaches that may be taken at different stages of the assay that are more s…
Effect of sensory exposure on liking for fat- or sugar-reduced biscuits
2015
This study investigates the effect of exposure to fat- or sugar-reduced biscuits on liking for these products. Two sets of biscuits were manufactured, each including a standard variant and 4 variants differing by the level of reduction of either fat or sugar content, to 33% of fat content or 28% of sugar content. Biscuit consumers were recruited to eat either the fat (n ¼ 113) or the sugar-reduced set of biscuits (n ¼ 106). They participated in 5 testing sessions, once a week, in laboratory conditions. During each session, they rated their liking of the 5 variants. At the end of each of the 4 first sessions, consumers were given 16 biscuits for their home consumption during the week. Partic…
Three-year clinical performance of two indirect composite inlays compared to direct composite restorations
2013
Objective: Despite the incremental build-up of resin composite restorations, their polymerization shrinkage during curing presents a serious problem. Indirect composite resin systems represent an alternative in overcoming some of the deficiencies of direct composite restorations. The hypothesis of the present study states that the clinical performance of restorations may be affected by different generation and application techniques. Study Design: Sixty restorations (20 DI system (Coltene/Whaledent AG, Altstatten, Switzerland) composite inlays, 20 Tescera ATL system (BISCO Inc. Schaumburg, Illinois, USA) composite inlays, and 20 direct composites) were applied to premolar teeth in 49 patien…
Deep venous thrombosis: Behaviour of the polymorphonuclear leukocyte integrin pattern at baseline and after in vitro activation
2005
In a group of 18 subjects with acute deep venous thrombosis (DVT), evidenced by clinical examination and echo-color-Doppler, we examined the phenotypical expression of the polymorphonuclear leukocyte (PMN) beta2-integrins (CD11a, CD11b, CD11c, CD18), obtained by using a flow cytofluorimeter. The evaluation was performed before and after in vitro activation (prolonged for 5 and 15 minutes) with 4-phorbol 12-myristate 13-acetate (PMA) and N-formyl-methionyl-leucyl-phenylalanine (fMLP). In DVT subjects, at baseline, the phenotypical expression of CD11b was decreased and that of CD11c was increased when compared with normal controls; no difference was found in CD11a and CD18 expression. In norm…
Prolonged Grief Disorder, Depression, and Posttraumatic Stress Disorder Among Bereaved Kosovar Civilian War Survivors: a Preliminary Investigation
2010
Background: This study aimed at examining diagnostic concordance between Prolonged Grief Disorder (PGD), Major Depressive Disorder (MDD), and Posttraumatic Stress Disorder (PTSD) among bereaved war survivors who had lost relatives due to war-related violence.Method: We investigated the rates of PGD and its association with PTSD and MDD among 60 bereaved people who had lost first-degree relatives due to war-related violence seven years ago and had also experienced other war-related events.Results: The results indicated that 38.3% of the sample fulfilled the criteria for PGD, 55.0% for PTSD, and 38.3% for MDD. Thirty per cent of the participants without PTSD and 21.6% of those without MDD met…
Nitric oxide metabolites and erythrocyte deformability in a group of subjects with obstructive sleep apnea syndrome
2014
Our aim was to evaluate nitric oxide metabolites (nitrite and nitrate), expressed as NOx, and erythrocyte deformability, expressed as elongation index, in a group of subjects with obstructive sleep apnea syndrome (OSAS). We enrolled 48 subjects (36 men and 12 women; mean age 50.3 ± 14.68 yrs) with OSAS diagnosed after a 1-night cardiorespiratory sleep study. OSAS severity was assessed evaluating the apnea/hypopnea index (AHI) and subjects were subdivided in two subgroups: Low (L = AHI 30). NOx was examined converting nitrate into nitrite with a nitrate reductase and then assessing nitrite with spectrophotometry after the addition of Griess reagent. The elongation index was obtained using th…
Long-term functional results of digital replantation: A survey of 28 patients
2019
We sought to evaluate the long-term quality of life and functional outcome of patients who underwent digital replantation after amputation. A retrospective single-center study was conducted of patients treated between January 2010 to May 2016. Twenty-eight patients who underwent successful replantation after single or multiple digital amputation were reviewed in person after at least 2years' follow-up (mean 4.6years). Total active range of motion, grip and pinch strength were assessed. Functional outcomes were evaluated using the SF-36 and DASH questionnaires. The patients' occupational status and daily activities were reported. Mean total active range of motion was 42% of the contralateral…
Holes in teeth - Dental caries in Neolithic and Early Bronze Age populations in Central Germany.
2015
This study provides diachronic insight into the epidemiology of carious defects in teeth of Neolithic and Early Bronze Age populations in Central Germany over a period of 4000 years. The data were retrieved from skeletal remains uncovered at 21 sites throughout the Middle Elbe-Saale region (MES), comprising a total of 494 individuals with preserved teeth. The data generated were examined for age- and sex-related differences in order to gain information about the dietary habits and socio-economic structures of the period with the goal of identifying potential diachronic changes. The results indicated that dietary habits changed over the course of the Neolithic period: the prevalence of carie…
Elevated concentration of oxidized LDL together with poor cardiorespiratory and abdominal muscle fitness predicts metabolic syndrome in young men
2013
Metabolic syndrome (MetS) is associated with increased oxidized LDL (ox-LDL), systemic inflammation, and poor cardiorespiratory fitness. We examined affiliations of these factors and the effect of muscular fitness on MetS in young healthy men.Physical fitness, ox-LDL, tumor necrosis factor α (TNFα), interleukin-6 (IL-6) and serum lipids were measured in a nationally representative sample of Finnish young men with and without MetS. Participants (mean age 25.1years) performed tests of maximal oxygen uptake (VO₂max) and muscle fitness, and were divided into MetS (n=54, IDF 2007 criteria) and non-MetS (n=790). Age, smoking and leisure-time physical activity were used as covariates (ANCOVA).The …
