Disentangling relations between the desirability of the thin-ideal, body checking, and worry on college women's weight-loss dieting
2019
The study used self-regulation theory to elucidate the relationships between the desirability of the thin-ideal goal, dispositional worry, body checking and weight-loss dieting (WLD) in college women. We hypothesized that body checking would mediate the relationship between the desirability of the thin-ideal goal and WLD: the desire to be thin would be associated with more WLD through more frequent body checking. We also hypothesized that dispositional worry would moderate this mediation pathway, such that the mediation pathway would be stronger for those higher in worry. Finally, all effects were expected to occur when controlling for self-reported body size. A paper and pencil survey was …
Assessing positive body image, body satisfaction, weight bias, and appearance comparison in emerging adults: A cross-validation study across eight co…
2020
Positive body image refers to individuals' ability to conceptualize their bodies with love, respect, and appreciation. The study of positive body image is relatively new, and instruments used to investigate this multi-faceted construct have received limited use in non-English speaking countries. Thus, the aim of this investigation is to consider four measures that are associated with positive body image across eight different countries. Participants (n = 6272) completed the Body Appreciation Scale-2, the Body Areas Satisfaction Scale, the Physical Appearance Comparison Scale, and the Weight Bias Internalization Scale. Multi-group confirmatory factor analyses (MG-CFAs) and item-response theo…
Inhibition of Fcγ Receptors in the Plasma of Subjects with Down's Syndrome
1993
Abstract Subjects with Down's syndrome have several immunological abnormalities. We examined the sera of 29 subjects with Down's syndrome for the presence of Fcγ receptor blocking and for the presence of anti-ssDNA antibodies by EA rosette inhibition. Fifty-five percent of Down subjects had levels of inhibition above the upper limit of normality in comparison to 7% of normal controls. The finding that after polyethylene glycol precipitation of selected sera giving high levels of EA rosette inhibition there was a reduction or a disappearance of the EA rosette inhibition could indicate that the blocking factors detected behaved as immune complexes. Since almost all subjects with anti-ssDNA an…
Comparison of cystatin C and creatinine-based glomerular filtration rate formulas with 51Cr-EDTA clearance in patients with cirrhosis
2011
Renal function is an important predictor of survival in cirrhosis and liver transplantation. GFR estimates using serum cystatin C (CysC) are proposed as better predictors of renal function than ones on the basis of serum creatinine (Cr). Our aims were: (1) evaluate correlations between serum CysC and different methods of creatinine measurements; (2) compare CysC and Cr GFR formulas with (51)Cr-EDTA; and (3) evaluate liver-related parameters potentially influencing GFR.254 blood samples in 65 patients with cirrhosis correlating CysC with four Cr methods were used; another 74 patients comparing (51)Cr-EDTA GFR to Modification of Diet in Renal Disease and Larsson and Hoek formulas for CysC wer…
Dose-dependent absorption and elimination of cefadroxil in man.
1991
The pharmacokinetic behaviour of cefadroxil was dose-dependent in healthy male volunteers following the oral administration of single doses of 5, 15, and 30 mg.kg-1. As the dose of cefadroxil increased from 5 to 15 and 30 mg.kg-1, the peak plasma concentrations, normalized to 5 mg.kg-1, decreased significantly from 15.1 to 10.7 and 7.6 mg.l-1, while the corresponding normalized areas under the plasma concentration-time curves from 0 to 2 h decreased significantly from 1258 to 946 and 801 min.mg.l-1. When the same subjects were given 5 mg.kg-1 of cefadroxil together with 45 mg.kg-1 of cephalexin, the absorption of cefadroxil was slowed to a similar or greater extent than with the high dose o…
'Prefrontal' cognitive performance of healthy subjects positively correlates with cerebral FDOPA influx: an exploratory [18F]-fluoro-L-DOPA-PET inves…
2006
Dopamine neurotransmission influences those cognitive processes, which are generally regarded as prefrontal cortical functions. In previous positron‐emission‐tomography (PET) studies, net blood‐brain clearance of [(18)F]‐fluoro‐l‐DOPA (FDOPA) correlated with impaired cognitive performance in patients with Parkinson's disease or schizophrenia. We hypothesized that FDOPA influx also correlates with performance of cognitive tasks associated with prefrontal functioning in healthy volunteers. The net blood‐brain clearance of FDOPA (K [Formula: see text]) was mapped in a group of 11 healthy volunteers and calculated in striatal volumes‐of‐interest. The Wisconsin‐Card‐Sorting‐Test (WCST), Stroop‐T…
Probable progress in the therapy of organophosphate poisoning
1976
Whether or not extracorporeal hemodialysis or hemoperfusion with coated activated charcoal might be used in eliminating organophosphates following poisoning with nitrostigmine, demeton-S-methyl sulfoxide, or dimethoate was here examined. Nitrostigmine could not be hemodialysed. The other two organophosphates, on the other hand could be well eliminated from the blood by hemodialysis. The clearance rates for demeton-S-methyl sulfoxide and dimethoate were 52.98 ml/min and 59.07 ml/min respectively, at a blood flow rate of 100 ml/min. The clearance values for hemoperfusion with coated activated charcoal were higher under the same trial conditions, the values being 83.70 ml/min for demeton-S-met…
The viral clearance in interferon-treated chronic hepatitis C is associated with increased cytotoxic T cell frequencies
1999
Abstract Background/Aims: Cytotoxic T lymphocytes have been demonstrated in peripheral blood and liver tissue of patients with chronic hepatitis C virus infection, but their significance for viral clearance is unknown. Therefore, we analyzed hepatitis C virus-specific cytotoxic T lymphocyte precursor frequencies in chronic hepatitis C virus carriers during interferon-α treatment. Methods: Blood mononuclear cells or CD8+ T cells from HLA-A2 positive and negative patients and controls were analyzed in chromium-release assays using a panel of 18 synthetic peptides from the HCV core, E1 and NS4 antigens bearing HLA-A2 binding motifs. Specific cytotoxic T lymphocyte precursor frequencies were st…
Escalation from normal appearance related intrusive cognitions to clinical preoccupations in Body Dysmorphic Disorder: A cross-sectional study
2018
Abstract Current cognitive approaches to Body Dysmorphic Disorder (BDD) assume that appearance-related intrusive cognitions and their functional consequences characterize the disorder, in a similar way that obsessive intrusive thoughts characterize the Obsessive-Compulsive Disorder (OCD). This study explores whether normal but unwanted appearance-related intrusive thoughts (AITs), escalate to clinical AITs when they are dysfunctionally appraised and instigate counterproductive neutralizing strategies. From a sample of 344 non-clinical individuals who reported a highly upsetting AIT during the past three months two subgroups were extracted according to their high (n = 68) and low (n = 276) v…
Topical Antibiotic, Antifungal, and Antiseptic Solutions Decrease Ciliary Activity in Nasal Respiratory Cells
2002
This study was designed to investigate whether topical solutions, as they are used in the treatment of selected cases of rhinosinusitis, influence nasal mucociliary clearance. The objective of this study was to evaluate the effects of the following topical solutions on the ciliary beat frequency (CBF) of nasal respiratory cells: ofloxacin as an antibiotic; Betadine and hydrogen peroxide (H2O2) as antiseptic; and amphotericin B, itraconazole, and clotrimazole as antifungal solutions. Differences are described between effects of each of these substances and we clarify whether ciliotoxic effects are dose dependent and if they can be reduced or eliminated by diluting the concentration of the a…
