A comprehensive data linkage system for the detailed investigation of occupational cancer has newly been established in the Danish Cancer Registry, providing employment histories back until 1964. Based on this system a study of 839 cases of cancer of the nasal cavities, sinuses and rhinopharnyx and 2,465 cancer controls diagnosed in Denmark during the(More)
AIM To evaluate the high-resolution CT findings of severe asthma (SA) and bronchiolitis obliterans (BO) and determine whether any reliable discriminating HRCT features exist. MATERIALS AND METHODS HRCT examinations of the chest of 30 patients with SA and 14 patients with BO were analysed. Images were scored for the presence and extent of 21 CT findings.(More)
A method for immunological detection of acetylcholinesterase (AChE) and cholinesterase (ChE) in amniotic fluid is described. By addition of a small amount of antihuman-erythrocyte membrane antibody or anti-pseudocholinesterase antibody to the sample before electrophoresis the two esterase bands on polyacrylamide gel (PAG) can be absorbed away.

The hydrophilic, salt-soluble (SS) form of acetylcholinesterase (AChE) from bovine brain caudate nucleus exists mainly as a tetramer sedimenting at 10.3S (approximately 40%), and a monomer sedimenting at 3.4S (approximately 60%). The enzyme is N-glycosylated and contains similar HNK-1 carbohydrates as detergent-soluble (DS) AChE. No O-linked carbohydrates(More)
Diet choice was determined for wild-caught wood mice (Apodemus sylvaticus L.), temporarily confined to cages in the field and offered a choice of 24–26 types of seeds and fruits in 2-h sessions throughout the night. The mice showed an overall preference for some foods over others. The set-up minimized influences on food preferences of predation risk,(More)
Scent marking in mice allows males to communicate information such as territory ownership, male competitive ability and current reproductive, nutritional, social and health status. It has been suggested that female mice eavesdrop on these olfactory cues, using them as a means of selecting mates with dissimilar major histocompatibility complex (MHC) genes,(More)
A recent model of microtine cycles has hypothesized that plant chemical defences can drive the precipitous decline phase, through periodic lethal toxin production (PLTP) by non-preferred plant foods. Here we enumerate possible mechanisms using a previously published model of optimal foraging by one consumer (microtine rodent) of two types of food plant (1(More)
House mice (Mus domesticus) communicate using scent-marks, and the chemical and microbial composition of these 'extended phenotypes' are both influenced by genetics. This study examined how the genes of the major histocompatibility complex (MHC) and background genes influence the volatile compounds (analysed with Gas Chromatography Mass Spectrometry or(More)
We describe here a new instrument for the simultaneous, in situ measurement of the stratospheric tracer molecules, nitrous oxide (N2O) and methane (CH4). Argus is unique in its small size making it well suited for limited payload atmospheric research platforms. Argus employs second harmonic spectroscopy using tunable lead-salt diode lasers emitting in the(More)
Fifty-nine persons, 23 chronic alcoholics and 36 normal healthy persons with a well described alcohol consumption, had the serum concentration of alpha-fetoprotein determined by a sensitive monoclonal immunofluorescent assay. A significant elevation in S-AFP was found in alcoholics, median 4.1 kIU/l as compared to 3.0 kIU/l in near-abstainers (< 12 g(More)
