Contrary to the highly specialized epithelial cells of the mammalian auditory organ, little is known about the surrounding cells and, in particular, Boettcher's cells (BC). Our morphological studies show that, in rats, these cells began their differentiation around postnatal day 8 (P8) reaching maturity around P20, when they are completely covered by Hensen's and Claudius' cells. Tight junctions were noted near the apex of BC, providing that they were in direct contact with the endolymphatic space, between approximately P8 and P16. We observed gap junctions between BC and adjacent cells before the end of the covering process suggesting the additional involvement of BC in potassium recycling into the endolymph. Adherens junctions were also seen between BC throughout their maturation. Importantly, we noticed cytoplasmic secretory granules and an accumulated material, probably a secretion, in the intercellular space, between P8 and P25. These results indicate that BC could basally take part in the secretion of the extracellular matrix of the basilar membrane. Finally, we show that the basolateral interdigitations of BC are longer and more tighlty grouped at maturity and harbour urea transporters as early as P18. Our observations thus support the view that BC perform several functions. [less ▲]

The aim of this study was to investigate the carbohydrate composition of mucosubstances in the equine guttural pouches using conventional histochemical tests in conjunction with glycolytic digestion to degrade different classes of glycosoaminoglycans. In the goblet cells, the mucopolysaccharides contained chondroitin sulfate B, heparin, heparan sulfate and sialic acid residues. The acinar cells also expressed these substances (except for heparin), whereas the ductal cells produced chondroitin sulfate B and sialic acid. Neutral sugars were also found in each cell type. The diversity of the glycocomponents found in the auditory tube suggests that they may have important functional roles. Indeed, the glycosoaminoglycans provide a hydrophilic environment that prevents dehydration and desiccation of the guttural membranes during air passage. Additionally, these glycomolecules may be involved in the pathogenesis of some bacterial disease in horses, such as equine strangles. [less ▲]

Polymorph minerals are natural materials that share the same composition but have a different structure. Traditionally, the characterization of polymorphs has been done using different techniques of microscopy, X-ray diffraction Raman or IR Spectroscopy for instance. In this work we propose the use of a new technique as an alternative to characterise polymorphs: Ion Beam Induced Luminescence (IBIL). As an advantage to the other techniques, IBIL can be carried out simultaneously with the PIXE technique or other Ion Beam Analysis techniques and the combination will yield results on elemental composition and luminescence properties at the same time. Different minerals have been analysed with IBIL as an example of application to the characterization of polymorphs and its correspondent spectra are explained in this paper. [less ▲]

Until recently, Kavet ethnic minority people traditionally practiced swidden agriculture and accessed natural resources in the uplands as an important, and unchallenged, part of their food system. This present study aims to trace the historical transformation of land use and tenure practices by Kavet communities in Kok Lak commune in the context of various state-driven and social-economic transformations. At commune level, we look at land use changes along with the migrations associated with these transformations. We also aim to understand how these changes have induced social differentiation between households as it relates to their entitlements, their production activities and their income structure. We examine the transformation in land use prompted by a multiplicity of drivers (demographic, economic, political, institutional and cultural) and in land tenure regimes through a land control matrix that differentiates between two types of rights (the land rights of the users and the rights to manage those rights given to the users). We discovered that the Kavet people have been resilient in protecting and promoting the core of their swidden territories and traditions; however, recent developments (including the establishment of the Virachey National Park (VNP) and market incentives) have considerably fragmented their land uses, cultural values and institutions. Through forced and free migration, some households have adopted new forms of agriculture (e.g. paddy, and annual and perennial non-rice crops) and converted their swidden land into cashew plantations, while others still rely solely on the practice of swidden agriculture as a lifestyle. By reviewing past transformations, by identifying the role swidden agriculture has had and the contribution it has made to the lives of the Kavet people, we recommend that efforts be made to conserve it in recognition of the pivotal role it plays in community development and to adopt better land use planning at local level. But proper consideration should also be given to the Kavet people who do not practice swidden agriculture. [less ▲]

For lack of sufficient human cartilage donors, chondrocytes isolated from various animal species are used for cartilage tissue engineering. The present study was undertaken to compare key features of cultured large animal and human articular chondrocytes of the knee joint. Primary chondrocytes were isolated from human, porcine, ovine and equine full thickness knee joint cartilage and investigated flow cytometrically for their proliferation rate. Synthesis of extracellular matrix proteins collagen type II, cartilage proteoglycans, collagen type I, fibronectin and cytoskeletal organization were studied in freshly isolated or passaged chondrocytes using immunohistochemistry and western blotting. Chondrocytes morphology, proliferation, extracellular matrix synthesis and cytoskeleton assembly differed substantially between these species. Proliferation was higher in animal derived compared with human chondrocytes. All chondrocytes expressed a cartilage-specific extracellular matrix. However, after monolayer expansion, cartilage proteoglycan expression was barely detectable in equine chondrocytes whereby fibronectin and collagen type I deposition increased compared with porcine and human chondrocytes. Animal-derived chondrocytes developed more F-actin fibers during culturing than human chondrocytes. With respect to proliferation and extracellular matrix synthesis, human chondrocytes shared more similarity with porcine than with ovine or equine chondrocytes. These interspecies differences in chondrocytes in vitro biology should be considered when using animal models. [less ▲]
