The wound watch: an objective staging system for wounds in the diabetic (db/db) mouse model.

As in cancer biology, in wound healing there is a need for objective staging systems to decide for the best treatment and predictors of outcome. We developed in the diabetic (db/db) wound healing model, a staging system, the "wound watch," based on the quantification of angiogenesis and cell proliferation in open wounds. In chronic wounds, there is often a lack of cellular proliferation and angiogenesis that leads to impaired healing. The wound watch addresses this by quantifying the proliferative phase of wound healing in two dimensions (cellular division and angiogenesis). The results are plotted in a two-dimensional graph to monitor the course of healing and compare the response to different treatments.

Tennessee Williams's Cat on a hot tin roof or the dramatic aptitudes of the goddess Diana

The aim of this article is to show which are the dramatic "yields" of the inclusion of the reference to the goddess Diana in Tennessee Williams's Cat on a Hot tin Roof. In the author's opinion, it does not deal simply with a meaningful reference; on the contrary, the accurate analysis of Williams's text proves that it is a true nuclear and cohesive element of the whole drama.

Indagación edípica e ironía trágica: el modelo sofocleo en Cat on a Hot Tin Roof de Tennessee Williams

Dado que el referente clásico "Edipo en busca de su identidad" ha sido siempre reconocido para Suddenly Last Summer , el autor de este artículo, mediante un análisis minucioso del texto del dramaturgo americano, propone leer en este caso Cat on a Hot Tin Roof desde el modelo Edipo Rey de Sófocles y descubrir en él igualmente la tradicional ironía clásica tanto desde el punto de vista del espectador como de los mismos personajes principales, Brick y su padre, ambos en busca de su verdad, una verdad, claro está, contraria a la esperada.

Atès que el referent clàssic "Èdip en cerca de la seva identitat" ha estat sempre reconegut per a Suddenly Last Summer, l'autor d'aquest article, mitjançant una anàlisi acurada del text del dramaturg americà, proposa de llegir en aquest cas Can on a Hot tin Roof des del model Èdip Rei de Sòfocles i descobrir-hi igualment la tradicional ironia clàssica tant des del punt de vista de l'espectador com dels mateixos personatges principals, Brick i el seu pare, ambdós en cerca de la seva veritat, una veritat, és clar, contrària a la que esperaven.

Cat on a hot tin roof de Tennessee Williams o les aptituds dramàtiques de la deessa Diana

L'objectiu d'aquest article és mostrar quins són els rèdits dramàtics de la inclusió de la referència a la deessa Diana a Cat on a Hot Tin Roof de Tennessee Williams. En opinió del autor, no es tracta simplement d'una referència significativa, sinó que l'anàlisi acurada del text de Williams demostra que és un element vertaderament nuclear i cohesionador de tot el drama.

Substrate influence on the properties of doped thin silicon layers grown by Cat-CVD

We present structural and electrical properties for p- and n-type layers grown close to the transition between a-Si:H and nc-Si:H onto different substrates: Corning 1737 glass, ZnO:Al-coated glass and stainless steel. Structural properties were observed to depend on the substrate properties for samples grown under the same deposition conditions. Different behaviour was observed for n- and p-type material. Stainless steel seemed to enhance crystallinity when dealing with n-type layers, whereas an increased crystalline fraction was obtained on glass for p-type samples. Electrical conduction in the direction perpendicular to the substrate seemed to be mainly determined by the interfaces or by the existence of an amorphous incubation layer that might determine the electrical behaviour. In the direction perpendicular to the substrate, n-type layers exhibited a lower resistance value than p-type ones, showing better contact properties between the layer and the substrate.

Shutterless deposition of phosphorous doped microcrystalline silicon by Cat-CVD

In this paper we present results on phosphorous-doped μc-Si:H by catalytic chemical vapour deposition in a reactor with an internal arrangement that does not include a shutter. An incubation phase of around 20 nm seems to be the result of the uncontrolled conditions that take place during the first stages of deposition. The optimal deposition conditions found lead to a material with a dark conductivity of 12.8 S/cm, an activation energy of 0.026 eV and a crystalline fraction of 0.86. These values make the layers suitable to be implemented in solar cells.

The auditory pathway in cat corpus callosum.

The cortical auditory fields of the two hemispheres are interconnected via the corpus callosum. We have investigated the topographical arrangement of auditory callosal axons in the cat. Following circumscribed biocytin injections in the primary (AI), secondary (AII), anterior (AAF) and posterior (PAF) auditory fields, labelled axons have been found in the posterior two-thirds of the corpus callosum. Callosal axons labelled by small individual cortical injections did not form a tight bundle at the callosal midsagittal plane but spread over as much as one-third of the corpus callosum. Axons originating from different auditory fields were roughly topographically ordered, reflecting to some extent the rostro-caudal position of the field of origin. Axons from AAF crossed on average more rostrally than axons from AI; the latter crossed more rostrally than axons from PAF and AII. Callosal axons originating in a discrete part of the cortex travelled first in a relatively tight bundle to the telo-diencephalic junction and then dispersed progressively. In conclusion, the cat corpus callosum does not contain a sector reserved for auditory axons, nor a strictly topographically ordered auditory pathway. This observation is of relevance to neuropsychological and neuropathological observations in man.

Plaies douloureuses: un défi quotidien, non une fatalité [Painful wounds : a daily challenge, not a fatality]

Long neglected, the pain related to wounds is nowadays recognized as an important issue. This article reviews the physiopathological mechanisms and the types of pain related to wounds, their assessment modalities as well as the pharmacological and non-pharmacological analgesic treatments.

Protocole pour l'évaluation et la prise en charge des plaies chroniques [Protocol for the evaluation and treatment of chronic wounds in the home care setting]

In 2001, it became evident that the domiciliary care nurses needed a tool to assist them in treating patients with chronic wounds. A protocol was therefore developed which could be used not only by the nurses but also by doctors and other health care professionals working in home care. As a parallel measure, a network of nurses specialised in wound care and available for advice and consultation was established.

Neurons in the corpus callosum of the cat during postnatal development.

The corpus callosum (CC) is a major telencephalic commissure containing mainly cortico-cortical axons and glial cells. We have identified neurons in the CC of the cat and quantified their number at different postnatal ages. An antibody against microtubule-associated protein 2 was used as a marker of neurons. Immunocytochemical double-labelling with neuron-specific enolase or gamma-aminobutyric acid antibodies in the absence of glial fibrillary acidic protein positivity confirmed the neuronal phenotype of these cells. CC neurons were also stained with anti-calbindin and anti-calretinin antibodies, typical for interneurons, and with an anti-neurofilament antibody, which in neocortex detects pyramidal neurons. Together, these findings suggest that the CC contains a mixed population of neuronal types. The quantification was corrected for double counting of adjacent sections and volume changes during CC development. Our data show that CC neurons are numerous early postnatally, and their number decreases with age. At birth, about 570 neurons are found within the CC boundaries and their number drops to about 200 in the adult. The distribution of the neurons within the CC also changes in development. Initially, many neurons are found throughout the CC, while at later ages they become restricted to the boundaries of the CC, and in the adult to the rostrum of the CC close to the septum pellucidum or to the indusium griseum. Although origin and function of transient CC neurons in development and in adulthood remain unknown, they are likely to be interstitial neurons. Some of them have well-developed and differentiated processes and resemble pyramidal cells or interneurons. An axon-guiding function during the early postnatal period can not be excluded.
