Measurements have been made of the relative and total numbers of the various types of erythroid cells in the livers of random-bred Swiss foetal mice. It has been shown that the results can be interpreted in terms of two waves of erythropoiesis passing through the liver, one coinciding approximately with the erythropoietin sensitive phase of hepatic erythropoiesis, the other with the insensitive...

Background Chlamydia trachomatis is considered as an important cause of preventable sexually transmitted diseases worldwide. It is known to be of an obligate intracellular nature and enters its target cells via an endocytic process. As major outer membrane protein (MOMP) is one of the main candidates for the attachment and entry of chlamydia to the host cells we have tried to label the epitopes...

OBJECTIVE A potential psychological harm of screening is unexpected diagnosis-labelling. We need to know the frequency and severity of this harm to make informed decisions about screening. We asked whether current evidence allows an estimate of any psychological harm of labelling. As case studies, we used two conditions for which screening is common: prostate cancer (PCa) and abdominal aortic a...

A novel method is presented which allows the estimation of the velocity of migrating cells from positional 3HTdR labelling data in spatially organized epithelial tissues. In a continuum approach, wave-like profiles of labelling index (LI) data, which travel away from the basal layer, are followed and compared with experimental LI profiles. The method yields estimates of migration velocity, cell...

We address the problem of finding nice labellings for event structures of degree 3. We develop a minimum theory by which we prove that the index of an event structure of degree 3 is bounded by a linear function of the height. The main theorem of the paper states that event structures of degree 3 whose causality order is a tree have a nice labelling with 3 colors. We exemplify how to use this th...

The size of the pericryptal fibroblast sheath (PCFS) population was determined by scoring serial sections. There are 38 and 124 PCFS cells per murine small intestinal and colonic crypt, respectively. The cells of the PCFS are slightly weighted towards the lower two-thirds of the crypt in their distribution. The ratio of epithelial cells to PCFS cells is approximately 6.5:1. The in vivo cell kin...

This paper presents SLAM : a simple method for the automatic Stylization and LAbelling of speech Melody. This main contributions over existing methods are : the alphabet of melodic contours is fully data-driven, an explicit time-frequency representation is used to derive complex melodic contours, and melodic contours can be determined over arbitrary prosodic/syntactic units. Additionally, the s...

In computational models of argumentation, argument justification has attracted more attention than statement justification, and significant sensitivity losses are identifiable when dealing with the justification of statements by otherwise appealing formalisms. This paper reappraises statement justification as a formalism-independent component in argument-based reasoning. We introduce a novel ge...
