A cDNA coding for plaice (Pleuronectes platessa) α1-microglobulin (Leaver et al., 1994, Comp. Biochem. Physiol. 108B, 275-281) was expressed and purified from baculovirus-infected insect cells. Specific monoclonal antibodies were then prepared and used to isolate the protein from plaice liver and serum. Mature 28.5 kDa α1-microglobulin was found in both liver and serum. The protein consisted of an

BACKGROUND: Hypercholesterolemic mice lacking factors required for activation of CD4+ T cells are characterized by reduced development of atherosclerosis. Consequently, it has been assumed that atherosclerosis involves loss of tolerance against modified self-antigens generated in response to hypercholesterolemia and that presentation of such antigens on major histocompatibility complex class II (M

Visual cues provide an important means for aerial creatures to ascertain their self-motion through the environment. In many insects, including flies, moths, and bees, wide-field motion-sensitive neurons in the third optic ganglion are thought to underlie such motion encoding; however, these neurons can only respond robustly over limited speed ranges. The task is more complicated for some species o

Soil mapping is an essential method for obtaining a spatial overview of soil resources that are increasingly threatened by environmental change and population pressure. Despite recent advances in digital soil-mapping techniques based on inference, such methods are still immature for large-scale soil mapping. During the 1970s, 1980s and 1990s, soil scientists constructed a harmonised soil map of Eu

The degree of trophic specialization determines the ability of predators to cope with changing foraging conditions, but in predators that prey on hundreds of species it is challenging to assess, especially when prey identity varies among predator individuals and across space and time. Here, we test the hypothesis that a bat species foraging on flying insects like moths will show ample flexibility

Incubation experiments are the most common approach to measure methane (CH 4 ) oxidation potential in soils from various ecosystems and land-use practices. However, the commonly used headspace CH 4 injection into microcosms and the shaking of the soil slurry during incubation fully removes CH 4 (soil-born) and O 2 (air-born) gradients common in situ, and may also induce various errors and disturb

BACKGROUND: Follow-up with computed tomographic angiography is recommended after endovascular aneurysm repair, exposing patients to significant levels of radiation and iodine contrast medium. Dual-energy computed tomography allows virtual noncontrast (VNC) images to be reconstructed from contrast-enhanced images using a software algorithm. If the VNC images are a good-enough approximation of true

Time-varying spatially-coupled low-density parity-check convolutional codes (SC-LDPC-CCs) exhibit excellent features, but their representation requires a very large number of parameters. On the other hand, the description of time-invariant SC-LDPC-CCs is very convenient and their error rate performance, though usually worse, is often satisfactory. In this paper we investigate the girth properties

The field of microbial ecology has been developing rapidly, largely owing to the introduction of new molecular methods for identifying individuals, species and populations of microorganisms in nature. In contrast to traditional methods, the new ones do not require the isolation and culture of organisms from the environment. With many of the new methods, genotypes and species of microorganisms can

A major problem in accurately defining bacterial adhesion mechanisms and processes occurring in biofilms on surfaces is the lack of techniques that nondestructively provide on-line information about the microorganisms, their extracellular polymers, and metabolites. The attenuated total reflectance (ATR) technique of Fourier transform infrared spectroscopy (FT-IR) is ideally suited to monitor molec

Several studies have indicated that the capture of nematodes by the nematophagous fungus Arthrobotrys oligospora is mediated by a lectin on the fungal surface. One of the major surface proteins of this fungus showed haemagglutinating activity and was isolated by affinity chromatography using a mucin Sepharose column. Biochemical analysis showed that the protein was a dimeric glycoprotein with a mo
