Sialographic findings in Wharton duct evagination
2009
Ductal evagination is a rare condition affecting the Wharton duct. The aim of this study was to establish the incidence, imaging features and clinical significance of ductal evagination in patients undergoing submandibular gland sialography. The sialographic findings and reports of 322 patients undergoing submandibular gland sialography during the period 1998-2007 were retrospectively reviewed. Ductal evagination was identified on sialograms as a unique diverticulum, filled with contrast medium, of the Wharton duct, with a narrow neck and a blind end. A ductal evagination was found in 5/322 patients with swelling and pain in the submandibular gland. It was always located in the middle tract…
The massacre mass grave of Schöneck-Kilianstädten reveals new insights into collective violence in Early Neolithic Central Europe
2015
Conflict and warfare are central but also disputed themes in discussions about the European Neolithic. Although a few recent population studies provide broad overviews, only a very limited number of currently known key sites provide precise insights into moments of extreme and mass violence and their impact on Neolithic societies. The massacre sites of Talheim, Germany, and Asparn/Schletz, Austria, have long been the focal points around which hypotheses concerning a final lethal crisis of the first Central European farmers of the Early Neolithic Linearbandkeramik Culture (LBK) have concentrated. With the recently examined LBK mass grave site of Schöneck-Kilianstädten, Germany, we present ne…
The influence of alcohol on cognitive conflict.
1985
The influence of alcohol on cognitive conflict between individuals was studied by means of an experiment that was designed to be representative of real life negotiating situations, where alcohol is consumed and where two parties are required to find new common solutions to problems that they have previously learned to solve differently by themselves. The subjects were 60 male students of technology divided into experimental and control groups. The amount of alcohol (whisky) consumed by the experimental subjects produced approximately 0.08% blood alcohol concentration. In the experiment, the cognitive conflict situation was created by first training subjects to solve diagnostic medical tasks…
β2-adrenoreceptors control human skin microvascular reactivity.
2021
Topical α1- and α2-adrenoreceptor (ADRA1 and 2) agonists are effective in alleviating permanent vasodilation and facial erythema associated with rosacea by inducing skin vasoconstriction. Although β-adrenoreceptor (ADRB) antagonists are used off-label for rosacea, pharmacological and pharmacodynamic data pertaining to these receptors in skin micro-vessels are lacking. Objectives: To analyse the expression of different adrenergic receptors and their contribution to vasoreactivity in skin micro-vessels. Small arteries (500-800 μm) and arterioles (<200 μm) were studied in human foreskin tissue. Specifically, ADR-A1, -A2, -B1 and -B2 expression was assayed by immunofluorescence, polymerase chai…
Mitochondrial DNA copy number and telomere length in peripheral blood mononuclear cells in comparison with whole blood in three different age groups
2019
There are more and more studies on telomere length (TL) and mitochondrial DNA (mtDNA), and it has been proven that these factors play a significant role in the aging of the immune system thereby it is important to understand how it varies in different cell types for more accurate conclusions. The aim of this study was to look into dynamics of mtDNA amount in conjunction with TL in peripheral blood mononuclear cells (PBMC) during aging in comparison with whole blood (WB) cells. Overall, 53 samples were divided into three age groups: 20-39 year age group, 40-59 year age group and 60-79 year age group. MtDNA amount was determined by qPCR TaqMan, and TL was measured by Southern blotting of term…
Endothelium-dependent relaxation of human saphenous veins in response to vasopressin and desmopressin
1997
Purpose: The goal of this study was to determine the effects of vasopressin and the selective V 2 -receptor agonist desmopressin on human saphenous veins, with special emphasis on endothelium-mediated responses. Methods: Human saphenous vein segments were obtained from 35 patients undergoing coronary bypass surgery. Paired segments, one normal and the other deendothelized by gentle rubbing, were mounted for isometric recording of tension in organ baths. Concentration-response curves to vasopressin and desmopressin were determined in the presence and in the absence of either the V,-receptor antagonist d(CH 2 ) 5 Tyr(Me)AVP (10 −6 mol/L), the V 1 -V 2 receptor antagonist desGly-d(CH 2 ) 5 D-T…
Lisuride, a dopamine D2 receptor agonist, and anticraving drug expectancy as modifiers of relapse in alcohol dependence
2002
Due to a central role of dopamine in mediating ethanol intake and dependence, the authors tested lisuride, a dopamine D2 receptor agonist, for relapse prevention in alcoholics. Psychological and neuroendocrine determinants of outcome were also assessed within the study. This double-blind, placebo-controlled randomized study comprised 120 alcoholics who were subjected to an intend-to-treat analysis (ITT). After hospital detoxification, patients received an outpatient rehabilitation program and either the study medication or placebo for 6 months and follow-up for another 6 months without medication. Pharmacological and psychological effects on relapse and times to first drink were assessed us…
Eosinophil granule proteins in serum and urine of patients with helminth infections and atopic dermatitis.
2001
Eosinophil cationic protein (ECP) and eosinophil-derived neurotoxin (EPX) are cytotoxic molecules involved in helminth infections and allergic reactions. Hitherto most clinical chemical studies have been concerned with the analysis of serum ECP in allergic diseases. The aim of this study was to examine whether serum as well as urine levels of these proteins are useful clinical chemical parameters in helminthiases and allergic diseases such as atopic dermatitis. Comparing these diseases under the same methodological conditions, levels of ECP and EPX were generally higher in helminthiases than in atopic dermatitis and non-helminth, non-allergic diseases. The highest levels of both proteins oc…
Correlation of Skin Test Results and Specific Immunoglobulin E Blood Levels with Nasal Provocation Testing for House-Dust Mite Allergies
2016
Background Allergen-specific immunotherapy for house-dust mite (HDM) allergies is associated with lower success rates when compared with similar treatments for other inhalant allergens, such as grass or birch. One reason might be the greater difficulty in diagnosing patients with assumed HDM allergies because symptoms occur perennially and may differ from those of a conventional allergic rhinitis. Objective The aim of the study was to compare the different methods of diagnosis in patients with assumed HDM allergy. Methods We performed a retrospective analysis of nasal provocation tests (NPT) from patients (n = 161) evaluated for Dermatophagoides pteronyssinus (n = 127) and Dermatophagoides …
Use of Internet in an italian clinical sample
2012
This study is aimed at evaluating Internet use in a psychiatric population. We used the UADI questionnaire to investigate the degree of addictive Internet use in our sample of patients affected by various psychiatric disorders. Several psychological and psychopathological variables related to internet use, have been assessed through the five dimensions of the UADI: dissociation (DIS), Impact on real life (IMP), Experimentation (EXP), Dependence (DEP), Escape (ESC).
