Regeneration/repair and protection of auditory hair cells and auditory neurons is an exciting, rapidly evolving field. Simultaneous developments in the fields of otobiology and surgical otology have led to new and exciting possibilities in inner ear medicine and surgery; specifically, the treatment or prevention of a variety of types of hearing losses in the foreseeable future. Sensorineural hearing loss in humans is commonly associated with a loss of auditory hair cells. It has been generally accepted that hearing loss resulting from hair cell damage is irreversible because the human ear has been considered to be incapable of regenerating or repairing these sensory elements following severe injury. An organ of Corti explant study has shown that it is possible to initiate the regeneration/repair of mammalian hair cells. In this study, ototoxin-damaged organ of Corti explants from juvenile rats were treated with a combination of retinoic acid (10-8M) and fetal calf serum (10%). TGF-alpha has been identified as a growth factor capable of evoking auditory hair cell regeneration/repair in ototoxin-damaged organ of Corti explants. Preliminary in vitro experiments with juvenile rat organ of Corti explants and in vivo studies in the cochleae of adult guinea pigs indicate that pretreatment followed by continuous treatment of the inner ear with a combination of retinoic acid and TGF-alpha can protect the auditory hair cells from the ototoxic effects of aminoglycosides. Because the integrity of spiral ganglion neurons is also essential for normal auditory function, there is a parallel series of in vitro and in vivo studies of the effects of neurotrophic factors on the survival of auditory neurons and the regeneration of injured neuronal processes. Clinical studies have demonstrated that it is now possible to perform surgeries on the inner ear, i.e., partial or total labyrinthectomies, and maintain hearing. The field of cochlear implantation has also provided insights into both the short- and long-term effects of cochlear fenestration on inner ear function. Administration of growth factors to the inner ears of animals is now possible with the use of implanted catheters and miniature infusion pumps. These advances suggest that localized application of drugs to the human inner ear may be feasible. The aim of this paper has been to provide an overview of advances in the study of the biology of auditory hair cells and auditory neurons, as well as recent relevant surgical advances. Taken together, these advances in otobiology and surgery will, in the future, be combined to devise new and innovative treatments for inner ear disorders. [less ▲]

Dans le massif de l'Ossau, les petits mammifères d'origine méditerranéenne (Crocidura) ne dépassent pas en altitude l'étage collinéen. A l'étage montagnard, le milieu le plus rihe en espèces est constitué par les pierriers non dépourvus de végétation et entourés par la hêtraie sapinière. Ils abritent des rongeurs rupicoles et ceux qui ne sont pas strictement inféodés aux espaces herbeux découverts. La faune des petits insectivores dépend du degré d'humidité. Les taillis humides, les clairières bien arrosées et parsemées de buissons ainsi que les forêts mixtes à sous bois dense sont occupés par des populations abondantes de rongeurs et d'insectivores. Les pelouses surpâturées et les rhodoraies de l'étage subalpin sont pauvres en espèces. Il en est de même des pierriers à l'étage alpin. Toutefois, les quelques espèces qui y sont représentées peuvent former de petites populations denses et localisées à la faveur de micro millieux favorables. Les milieux les plus pauvres sont la futaie sombre à un seul étage de végétation et la rhodoraie intermédiaire entre la forêt et la pelouse alpine. [less ▲]

The bovine mastitis : from initiation to resolution The cure of a cow suffering from a bacterial mastitis relies on the balance between the eradication of the pathogen and the resolution of the inflammatory response, two processes that are essential to come back to a normal milk composition with low somatic cell count. The persistence of the inflammatory response, which main consequence is a reduction in milk yield, is a feature of chronic mastitis. This frequent disease depends on inappropriate host-pathogen interactions and is not yet well understood. This review resumes the main defence mechanisms of the bovine mammary gland, emphasizing the predominant roles played by the neutrophil, and brings some precisions on lipoxin implications in the resolution of inflammation. Reasons that may explain the persistence of the inflammatory reaction, a phenomenon found in the Staphylococcus aureus chronic mastitis, are also discussed. [less ▲]

Objectif général : Ces chapitres présentent les notions de base relatives à l'anatomie et la physiologie de la glande mammaire au cours du cycle de lactation naturellement ou artificiellement induit. Il précise également les caractéristiques générales du lait. Il présente également le contexte de la production laitière mondiale. Il décrit enfin le système de contrôle qualitatif et quantitatif de la production laitière en Wallonie. Ces notions constituent autant de prerequis indispensables à une bonne compréhension des chapitres plus spécifiques relatifs à la mammite (Chapitre 1). La mammite est une maladie de production qui présente diverses conséquences non seulement pour le producteur mais également pour le consommateur de lait et de ses dérivés. Une fois précisées la définition et les conséquences de la mammite, en seront successivement abordés les symptômes, les méthodes de diagnostic (Chapitre 2), l’étiologie (Chapitre 3), la pathogénie et le traitement (Chapitre 4). Le lecteur gardera en mémoire la double approche possible de cette pathologie : individuelle et de troupeau. [less ▲]

Au cours d'un exposé théorique présentant la revue de la littérature récente sur la mammite à coliforme, la pathophysiologie des différentes expressions cliniques sera abordée. La mammite à coliformes présente des risques majeurs de mortalité au post partum. Par ailleurs, cette affection présente des symptômes communs à d'autres affections mammaires du post-partum. Ainsi, le diagnostic clinique peut avoir des conséquences importantes en matière de choix de l'antibiotique par exemple. Par ailleurs, les techniques de fluidothérapie de base sont souvent sous-utilisées sur le terrain, pour des contraintes administratives liées à la cascade thérapeutique. Il est également marquant que cette affection entraîne des chutes importantes de production, ce qui implique que la gestion préventive de cette pathologie demeure au 21ème siècle une priorité pour le praticien moderne. Plusieurs aspects peuvent être évoqués au nombre desquels les équilibres nutritionnels du tarissement, la gestion thérapeutique du pré-partum, l'hygiène du péri-partum et le traitement intramammaire au tarissement. Enfin, la mammite colibacillaire demeure une urgence thérapeutique et trop peu souvent elle fait l'objet de conseil écrit de la part du thérapeute, ce qui, selon plusieurs études récentes, constitue en soi un facteur de risque.

Hormone production was studied in situ by immunocytochemical methods in 20 pituitary adenomas. Special attention was given to 13 adenomas removed from acromegalic patients. Out of them, 6 had mild to moderate hyperprolactinemia. Immunohistochemistry revealed PRL-containing cells without any close relationship with high PRL serum level in 6 patients. Double immunogold staining revealed mammosomatotrope cells characterized by simultaneous presence of GH and PRL in the same granules in 2 patients. Since mammosomatotropes have never been demonstrated in the normal pituitary, our results probably signify gene dysregulation in pituitary cells of those acromegalic patients. [less ▲]

Considering Neanderthal subsistence, the use of mammoth resources has been particularly discussed. Apart from procurement for food, the use of mammoth bones as building material has been proposed. The hypothesis was based on the discovery made in Molodova I, Ukraine (Dniester valley). In this large multistratified open-air site, a rich Mousterian layer was excavated. Dated to the Inter-Pleniglacial (MIS 3), it has yielded 40 000 lithic remains associated with ca. 3000 mammal bones, mostly from mammoth. Several areas have been excavated: a pit filled with bones, different areas of activities (butchering, tool production), twenty-five hearths and a circular accumulation made of mammoth bones, described as a dwelling structure set up by Neanderthals. Attested dwelling structures made of mammoth bones are known in Upper Paleolithic sites, from Ukraine and Russia, attributed to the Epigravettian tradition. This paper presents a zooarchaeological study of large mammal remains from Molodova I layer 4, to understand the modalities of acquisition and utilization of mammoth resources for food and technical purposes, especially to test the hypothesis of using bones as building elements. The number of mammoths is estimated to at least fifteen individuals of all age classes and both sexes, which died during several episodes, near or on the site. The taphonomic modifications due to weathering, water percolation and plant roots indicate the location of bones in holes, such as the pit and the basement of the circular accumulation. Secondary actions of carnivores, especially of hyaenid type, are rare on bones, showing that the assemblage was not accumulated by these predators. The anatomical preservation, the age and sex features and the taphonomic data indicate several modalities of mammoth acquisition by hunting, scavenging and collecting. Based on anthropogenic marks, mammoth meat has been eaten. The presence of series of striations and ochre on mammoth bones are associated with a technical or symbolic use. Furthermore, mammoth bones have been deliberately selected (long and flat bones, tusks, connected vertebrae) and circularly arranged. This mammoth bone structure could be described as the basement of a wooden cover or as a wind-screen. The inner presence of fifteen hearths, lithic artifacts and waste of mammal butchery and cooking is characteristic of a domestic area, which was probably the centre of a residential camp recurrently settled. It appears that Neanderthals were the oldest known humans who used mammoth bones to build a dwelling structure. [less ▲]
