Ein neuer weg zur herstellung von oligomeren aus acryl- und vinylverbindungen; modell einer matrizenreaktion
1966
In einer Reihe vorangehender Untersuchungen wurde die Herstellung molekulareinheitlicher, phenolischer Mehrkernverbindungen beschrieben. Sie besitzen je Phenolbaustein eine phenolische Hydroxylgruppe, wie systematisch untersuchte Acylierungen sowie Methylierung und Arylierung dieser Mehrkernverbindungen zeigen. In der vorliegenden Mitteilung wurde bei einer Zwei- und Dreikernverbindung an den phenolischen Hydroxylgruppen mit Acrylsaurechlorid umgesetzt, so das die entstandenen Verbindungen so viele polymerisationsfahige Reste wie phenolische Bausteine besasen. Die Polymerisation der Acrylsaurederivate in sehr groser Verdunnung gab oligomere Leiterverbindungen, die durch alkalische Hydrolyse…
The effects of muscular exercise on glucose, free fatty acids, alanine and lactate in type I diabetic subjects in relation to metabolic control.
1988
Metabolic effects of muscular exercise were studied in eleven subjects with type I diabetes mellitus during poor metabolic control, and again during good metabolic control, and in ten healthy control subjects. All the subjects were submitted to a submaximal gradual triangular test on an electrically braked bicycle ergometer; glucose, FFA, alanine and lactate were measured at rest, and after exercise. In poorly controlled patients, glucose and FFA were unchanged after exercise, whereas blood alanine and lactate increased by a percentage similar to that of the controls, and well-controlled diabetic patients. Baseline alanine concentrations were lower and lactate concentrations higher than in …
The evaluation of metabolic parameters and insulin sensitivity for a more robust diagnosis of the polycystic ovary syndrome
2007
BACKGROUND: Insulin glargine is a once-daily basal insulin analog with prolonged duration of action and absence of an evident peak. Glargine is associated with reduced frequency of hypoglycemic episodes (mostly nocturnal) as well as effective glycemic control. Maintenance of good metabolic control before conception and throughout pregnancy is essential to lower the risk of fetal malformations. Glargine might be a valuable alternative in the management of pregnancies complicated by diabetes mellitus. However, because its clinical utility has not been established, the use of glargine is not currently recommended during pregnancy. OBJECTIVE: The aim of this study was to retrospectively evaluat…
Methodical aspects of perceived exertion rating and its relation to pedalling rate and rotating mass.
1975
Methodical aspects of the relationship between pedalling rate and rotating mass and perceived exertion rating (PER; Borg, 1962) were studied in trained, untrained, and ill subjects in bicycle ergometry. Pedalling rate varied between 40 and 100 rpm, work load steps were 5, 10, 15 and 20 mkp/sec in the healthy subjects, and 2.5, 5, 7.5 and 10 mkp/sec in the patients. PER decreased with increasing pedalling rate in all healthy subjects. In the patients, PER increased moderately at work load of 2.5 mkp/sec, but decreased at higher work loads up to 80 rpm, followed by a slight increase at 100 rpm. Higher mass of the flywheel, studied in 6 trained subjects, lowered the PER insignificantly. In the…
Biomechanics of simulated versus natural cross-country sit skiing
2017
The purpose of this study was to investigate the biomechanics of cross-country sit-skiing in simulated and natural skiing. Thirteen international level athletes participated in a ski ergometer test (simulated conditions) and a test on snow in a ski-tunnel (natural conditions) using their personal sit-ski. Tests in both conditions were performed at individual maximal speed. When comparing the two conditions the main results were: (1) maximal speed in simulated conditions was lower (p < 0.05) but correlated well with the natural condition (r = 0.79, p < 0.001); (2) no differences in pole force variables were found; peak force (r = 0.77, p < 0.01) and average force (r = 0.78, p < 0.01) correla…
[A gastric polypoid signet ring cell carcinoma]
2007
The authors signal a case of gastric polypoid signet ring cell carcinoma, of particular interest for its rarity like show from the review of the literature, which is the first to have been described after Tabaru's citation.The study has been carried out at the Department of Surgical and Oncological Sciences of the University of Palermo. It has been based on 2000 cases analysed from June 2001 to December 2003.The authors advance some and emphasizes the diagnostic flow chart and therapeutic choices adopted.We agree that the endoscopic polypectomy is surgical procedure of first approach, but modifying the therapeutic guideline in relation to histologic examination, like happened in the case in…
Preselection of cases through expert clinical and radiological review significantly increases mutation detection rate in multiple epiphyseal dysplasia
2006
Skeletal dysplasias are difficult to diagnose for the nonexpert. In a previous study of patients with multiple epiphyseal dysplasia (MED), we identified cartilage oligomeric matrix protein (COMP) mutations in only 36% of cases and suspected that the low-mutation detection rate was partially due to misdiagnosis. We therefore instituted a clinical–radiographic review system, whereby all cases were evaluated by a panel of skeletal dysplasia experts (European Skeletal Dysplasia Network). Only those patients in whom the diagnosis of MED was confirmed by the panel were screened for mutations. Under this regimen the mutation detection rate increased to 81%. When clinical–radiological diagnostic cr…
Mechanical work and efficiency in ergometer bicycling at aerobic and anaerobic thresholds
1987
Internal and external mechanical work, energy consumption and mechanical efficiency were studied in constant-load ergometer bicycling at five different power outputs below, equal to, and above the aerobic (AerT) and anaerobic (AnT) thresholds. The gross, net and true efficiencies of the whole body in five male subjects were calculated. The work against the external load was defined as the external mechanical work. The internal mechanical work was calculated as the sum of the increments of kinetic and potential energy in all body segments by using methods of film analysis. Total energy consumption was measured by combining aerobic and anaerobic energy production. When the power output of the…
Comparative analysis of observer depression scales
1985
Abstract The Hamilton Depression Scale (HAMD), Bech Rafaelsen Melancholia Scale (BRMS) and Montgomery Asberg Depression Rating Scale (MADRS) are analyzed according to mean discriminatory power, internal consistency, homogeneity and transferability. The analysis was done separately in different samples of patients with depressive syndromes: a) operationally defined depressive syndrome; b) Major Depressive Disorder (RDC); c) Major Depressive Disorder, endogenous type (RDC). BRMS and MADRS were superior to HAMD in all evaluated aspects. Further, the BRMS was superior to MADRS according to the criteria of homogeneity and transferability.
Agomelatine and Hepatotoxicity: Implications of Cumulated Data Derived from Spontaneous Reports of Adverse Drug Reactions
2013
Considering the antidepressant agomelatine (AGM) there is a discrepancy between the widespread knowledge of the potential of AGM to cause hepatotoxic adverse drug reactions (ADR) and the availability of corresponding published data. This impedes an adequate assessment of the hepatotoxicity profile of AGM. We conducted a query of the database of a German Medical Regulatory Body (BfArM) and analyzed spontaneous reports of hepatotoxic ADR. We identified n=58 cases of AGM-related hepatotoxic ADR. Most frequent ADR was asymptomatic increase of liver enzymes (79%); n=6 patients (10%) with AGM-related toxic hepatitis were reported. Characteristics of patients: female sex (69%), age > 50 years (mea…
