Objective: To analyze the distribution of 3 collagen types in healthy tympanic membranes, during healing of a perforation, and during infection. Design: Immunohistochemical study of collagen types I, II, and III in the tympanic membranes of healthy rats as well as during healing of a perforation and in the presence of infection with Streptococcus pneumoniae at various time points. Setting: Laborat

The CC chemokine receptor (CCR)9 is expressed on the majority of small intestinal, but few colonic, T cells, whereas its ligand CCL25 is constitutively expressed by small intestinal epithelial cells. As such, CCR9/CCL25 have been proposed to play a central role in regulating small intestinal but not colonic immune responses and thus to organize regionalized immunity within the intestinal mucosa. H

Interactions between two like-charged macroions in the presence of their counterions confined in a cylindrical cell have been investigated by Monte Carlo simulations. The mean force and the potential of mean force (pmf) as a function of the macroion separation have been determined at conditions at which short-range attractions become significant. As the electrostatic coupling is increased, the nat

We find the extreme programming methodology highly suitable for introducing undergraduate students to software engineering. To be able to apply this methodology at a reasonable teaching cost for large student groups, we have developed two courses that work in tandem: a team programming course taken by more than 100 students, and a coaching course taken by around 25 students. In this paper we descr

A method for the determination of hexahydrophthalic acid, a metabolite of hexahydrophthalic anhydride, in human urine has been developed. The urine was worked-up by liquid-solid extraction, esterified with boron trifluoride-methanol, and analysed by capillary gas chromatography and selected-ion monitoring. Hexadeuterium-labelled hexahydrophthalic acid was used as the internal standard. The precisi

In nuclear reactors plutonium and transplutonium isotopes are produced by multiple neutron capture of uranium and plutonium and are important for the energy production and their composition reflects the core burnout. Under normal operation these elements are not released to the environment in significant amounts. There are accordingly very few areas or source terms where exotic transplutonium elem

The effects of scattered actinic radiation on photomultipliers (Hamamatsu R-562) were investigated. Using cotton-wool to model dense biological preparations, it was found that the scattered actinic radiation received by the photomultiplier gives rise to phytochrome-like signals. This demonstrated the necessity to shield the photomultiplier from scattered actinic light for sensitive measurements wi

D. Briihl and A. W. Inhoff (1995) found that exterior letter pairs showed no privileged status in reading when letter pairs were presented as parafoveal primes. However, T. R. Jordan, S. M. Thomas, G. R. Patching, and K. C. Scott-Brown (2003) used a paradigm that (a) allowed letter pairs to exert influence at any point in the reading process, (b) overcame problems with the stimulus manipulations u

Unlike the Quebec classification system, which is based primarily on pathoanatomy, a new Swedish classification system is based on the site of functional impairment and disability. A prospective study was performed on 85 patients with whiplash-associated disorders grade II according to the Quebec classification. The patients were examined 3-36 months following trauma. A team of professionals with

In this article I focus on some of Joseph Margolis's contributions to medical ethics. I first discuss some of Margolis's normative and metaphysical views on death and abortion, particularly in his early work Negativities, as well as some of his metaphysical assumptions. Then these views and assumptions are related to his theory of persons and, by implication, his theory of culture, set forth in a

Chloroplasts isolated from a plant species, Dimorphotheca pluvialis Moench (Asteraceae), grown under visible light without supplementary UV-B radiation, have poor grana development. The dominant components in the membrane organizations are doublets and triplets of stroma lamellae. However, such chloroplasts possess the capacity for electron transfer through the whole photosynthetic chain, based on

1. Task-dependent modulation of cutaneous input to climbing fibres projecting to the C1, C2 and C3 zones in the cerebellar paravermal lobule V was investigated in awake cats during performance of a reaching task. 2. Climbing fibre responses resulting from low intensity (non-noxious) electrical stimulation of the ipsilateral superficial radial nerve were recorded as extracellular field potentials i
