The adult frog dorsal root ganglia (DRG) together with the sciatic nerve (ScN) has previously been shown to survive in organ culture for several days. If a local test crush is made at the beginning of culturing, there is an initial delay of about 3 days before the sensory axons start to grow into the distal nerve stump at a rate of about 0.6-0.9 mm/day. The present results showed that axonal growt

The sensory axons of the adult mouse sciatic nerve were shown to regenerate after a local test crush lesion in vitro in a serum-free medium. The average outgrowth distance of the leading axons after culturing for 3 days was 2.8 ± 0.1 mm, which was shorter than in vivo (3.8 ± 0.2 mm). With the use of a compartmentalised culture system we could show that regeneration was partially dependent on local

We have studied the role of protein kinase C (PKC) in peripheral nerve regeneration by using the cultured adult mouse sciatic nerve, which displays regrowth of sensory axons under serum-free conditions. By the use of immunohistochemistry we show that one of the isoforms of PKC, PKCβ, is present in the nerve cell bodies of normal nerves and is upregulated after injury. In spite of this, the specifi

Retinitis pigmentosa is a group of inherited retinal degenerative diseases characterized by the loss of photoreceptors and vision for which no effective treatment is available. Several animal models of retinitis pigmentosa are used to elucidate its pathogenesis and to devise therapies. The retinal degeneration (rd1) mouse is one such animal model in which rod-specific phosphodiesterase (PDE) is in

The effects of glial cell line-derived neurotrophic factor on axonal outgrowth and apoptosis were studied in vitro using explanted dorsal root ganglia-peripheral nerve preparations of adult mice. In gels of matrigel or collagen type 1, glial cell line-derived neurotrophic factor increased both the numbers and lengths of axons growing out of explanted preparations, although less effectively than ne

Recent literature has suggested how late-medieval families may have used financial markets to navigate the life cycle. Precious little is known about the precise connections between the life cycle and family on the one hand and investments in financial instruments on the other, though. We analyse late-medieval investment behaviour using a new dataset of hundreds of life annuities. Our data give ag

Recent changes in user employment of Internet based services, new deployment technologies for mobile networks as well as an ongoing realisation of fixed and mobile converged networks e.g. the EU FP7 project COMBO, are significant examples of enablers for increasing demands on DSL links. Investigating cross-layer dependencies between all layers in the OSI reference model becomes increasingly import

Companies adopt different rationales for purchasing in order to make production processes as efficient as possible. This paper presents the results of an investigation into how purchasing strategies can vary between companies and countries. Two industrialised building companies, one in Sweden and one in Australia, were the objects of study. The purpose was to compare and understand the rationale b

The purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length. However, a different picture is portrayed in the manufacturing industry, where the purchasing strategies are mostly long-term to secure supply for production. Industrialized building is at the crossroad between construction and manufacturing, which rThe purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length.

Retinitis pigmentosa (RP), an inherited blinding disease, is caused by a variety of different mutations that affect retinal photoreceptor function and survival. So far there is neither effective treatment nor cure. We have previously shown that poly(ADP-ribose)polymerase (PARP) acts as a common and critical denominator of cell death in photoreceptors, qualifying it as a potential target for future

In economic and management literature, the relationship between supplier and buyer can be more or less intimate. It can vary from market-driven with a constant change of suppliers to a value-driven relationship with one sole supplier. Purchasing strategies of construction companies have often been described as short-sighted, where price is the most considered aspect. Recent lean management literat

The goal of this paper is to investigate whether multiple correspondence analysis (MCA), a multivariate statistical technique, is a useful dimensionality-reduction tool in zooarchaeological and taphonomic studies. For this purpose, the focus is to detect and discuss traces of waste management. Animal bones from waste-related contexts at the Bronze Age site Asine, Greece, are investigated. The data

The actor’s practice and bodily training during the twentieth century are specifically related not only to different bodily techniques, but also to language, modern society, and the concept of freedom. Nationalism, anti-intellectualism, bodily and vitalistic purism, and a sceptical distance from the modern project at the beginning of the twentieth century serve as a starting point for a discussionThe actor’s practice and bodily training during the twentieth century are specifically related not only to different bodily techniques, but also to language, modern society, and the concept of freedom.

In this paper, we describe Langforia, a multilingual processing pipeline to annotate texts with multiple layers: formatting, parts of speech, named entities, dependencies, semantic roles, and entity links. Langforia works as a web service, where the server hosts the language processing components and the client, the input and result visualization. To annotate a text or a Wikipedia page, the user c

In this paper, we investigate the annotation projection of semantic units in a practical setting. Previous approaches have focused on using parallel corpora for semantic transfer. We evaluate an alternative approach using loosely parallel corpora that does not require the corpora to be exact translations of each other. We developed a method that transfers semantic annotations from one language to

In this paper, I describe systems and prototypes we created in the natural language processing group at Lund to extract structured knowledge from text. Starting from syntactic and semantic parsingcomponents,wedevelopedapplicationsthatcanhandlelargecorpora,typicallycomplete Wikipedia versions consisting of millions of documents and process text to identify entities and the relations between them.

We present a survey of the radiation background at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory, TN, USA during routine daily operation. A broad range of detectors was used to characterize primarily the neutron and photon fields throughout the facility. These include a WENDI-2 extended range dosimeter, a thermoscientific NRD, an Arktis 4He detector, and a standard NaI photo

Xylooligosaccharides (XOS) have gained increased interest as prebiotics during the last years. XOS and arabinoxylooligosaccharides (AXOS) can be produced from major fractions of biomass including agricultural by-products and other low cost raw materials. Endo-xylanases are key enzymes for the production of (A)XOS from xylan. As the xylan structure is broadly diverse due to different substitutions,
