Cycling to school is associated with lower BMI and lower odds of being overweight or obese in a large population-based study of Danish adolescents.

Background: Previous studies have been inconclusive concerning the effect of active transport on BMI. Our objective was to investigate the association between travel mode and BMI in a large community-based sample of Danish adolescents.

Methods: A cross-sectional survey on health and lifestyle was distributed to all pupils from the 7th to 9th grade (12-16 years of age) in the municipality of Odense, Denmark.

Self-administered tests as a screening procedure for pregnancy-related pelvic girdle pain.

The aim of this study was to investigate sensitivity and specificity of self-administrated tests aimed at pain provocation of posterior and/or anterior pelvis pain and to investigate pain intensity during and after palpation of the symphysis. A total of 175 women participated in the study, 100 pregnant women with and 25 pregnant women without lumbopelvic back pain and 50 non-pregnant women. Standard pain provocation tests were compared with self assessed tests.

Purification of a high molecular weight membrane protein by fast protein liquid chromatography: the ATPase complex of a thermophilic cyanobacterium.

Fast protein liquid chromatography (FPLC) with a strong anion-exchange (Mono Q) column is applied to the purification of a high molecular weight membrane protein. The ATPase complex of the thermophilic cyanobacterium Synechococcus 6716, partially purified by ammonium sulfate precipitation, was fractionated in the presence of the detergent octylglucoside. The ATPase complex containing fractions were eluted by a linear NaCl gradient at about 0.

Granulocyte enzyme mediated degradation of human fibrinogen in plasma in vitro.

Incubation of plasma with granulocyte enzymes in the presence of kallikrein inhibitor resulted in a prolonged thrombin time of the plasma and in an increased level of fibrinogen fragments, indicating that fibrinogen was digested. In accordance with this, fibrinogen digestion products could be purified by affinity chromatography from plasma after incubation with granulocyte enzymes. The isolated products resembled early X-like fibrinogen fragments, which are produced by limited digestion of purified fibrinogen with elastase.

Anticoagulant and calcium-binding properties of high molecular weight derivatives of human fibrinogen, produced by plasmin (fragments X).

Early plasmin degradation products (X fragments) of human fibrinogen were prepared in the presence of calcium-ions or EGTA, and purified on Sepharose 6B-CL. X fragments were characterized with respect to amino-terminal amino acids, polypeptide-chain composition, anticlotting properties and calcium-binding. Amino-terminal amino acids were alanine and tyrosine.

The significance of abnormal duodenal loop on radiological and clinical cure in infants with sliding hiatal hernia.

In a study, partly retrospective and partly prospective, there were 29 infants who had sliding hiatal hernia: their principal clinical features, the diagnostic criteria, treatment and cure rate were similar to those of other series. The study highlights associated duodenal anomalies which seem to influence the radiological but not the clinical cure rate. The findings can be contrasted with those in adults who have duodenal abnormalities with sliding hiatal hernias in that 21 out of 29 infants with sliding hiatal hernia had a normal duodenal loop.
