Staphylococcus (S.) aureus is a major pathogen for mastitis in dairy cattle. In most cases, S. aureus causes long-lasting subclinical and chronic bovine mastitis and leads to significant economic losses by reducing the quantity and the quality of the milk produced. The pathogenesis of S. aureus mastitis includes the ability to persist within host cells and involves multiple virulence factors including toxins, surface proteins and polysaccharides. The numerous vaccines that have been developed induce a specific immune response against these different factors. These different vaccine approaches are described and classified depending on the target antigen used. Moreover, some recent vaccine strategies against human S. aureus infections are also discussed and could eventually be used for the design of new bovine vaccines. Although most of bovine vaccines induce specific humoral response, to date, no vaccine has been described to protect efficiently against experimental and naturally occurred bovine S. aureus mastitis. In conclusion, this type of immune response and the broad antigenic variability of S. aureus strains can partially explain the lack of protection observed during most of vaccine trials. [less ▲]

L'angiogenèse tumorale est une caractéristique commune à toutes les tumeurs. Ce nouveau réseau vasculaire tumoral présente des anomalies structurelles et fonctionnelles conduisant inévitablement à une perfusion tumorale hétérogène et à l'apparition de zones hypoxiques. Classiquement, l'hypoxie tumorale réfère à une inadéquation spatiale entre les vaisseaux et les cellules tumorales (i.e. hypoxie chronique). Elle confère aux cellules tumorales une résistance aux traitements et favorise les métastases. L'aspect temporel du phénomène est complètement négligé dans l'hypoxie chronique. L'hypoxie intermittente (HI), permet de tenir compte de l'aspect transitoire et temporel du phénomène. L'HI se définit comme une fluctuation de la p02 due à des arrêts transitoires du flux sanguin dans les vaisseaux tumoraux. Le compartiment tumoral et le compartiment vasculaire souffrent tous deux de l'hypoxie. L'HI étend donc le concept d'hypoxie tumorale au réseau vasculaire et aux cellules qui composent les vaisseaux. Les conséquences sont une plus grande résistance de la tumeur aux traitements de radio- et de chimiothérapie, une augmentation des métastases, mais également une résistance vasculaire accrue avec une diminution de l'apoptose des cellules endothéliales et une potentialisation de l'angiogenèse. L'identification et la compréhension des causes et des origines de l'HI permettent l'édification de nouvelles approches thérapeutiques. [less ▲]

Recording of a regular wide QRS tachycardia is often source of panic and anxiety for the young clinician who has to make the differential diagnosis between ventricular tachycardia and supraventricular tachycardia with aberration associated with fundamentally different vital prognosis. Most of the time, a rigorous approach and a systematic analysis of the electrocardiogram associated with clinical examination allow to obtain the correct diagnosis. [less ▲]

Vitamin D is well known for its beneficial effects on phosphocalcic homeostasis. The discovery of the role of vitamin D in cancers, infections, cardiovascular or autoimmune pathologies have promoted interest for this molecule. Skin and vitamin D are closely related. The skin is not only the site of vitamin D synthesis, but also a target organ as calcitriol plays an important hormonal and regulatory role, acting on cell proliferation, differentiation and immunomodulation. Furthermore, vitamin D influences the incidence and therapeutic response of certain dermatoses. In addition, many medical situations, mainly dermatological, require strict photoprotection and may therefore indirectly be responsible for a vitamin D deficiency in patients. The current role of vitamin D in skin cancers, inflammatory and autoimmune skin diseases is summarized. [less ▲]

Composites of magnetoresistive La0.7Ca0.3MnO3 (LCMO) with insulating Mn3O4 are useful as a model system because no foreign cation is introduced in the LCMO phase by interdiffusion during the heat treatment. Here we report the magnetotransport properties as a function of sintering temperature Tsinter for a fixed LCMO/Mn3O4 ratio. Decreasing Tsinter from 1250°C to 800°C causes an increase in low field magnetoresistance (LFMR) that correlates with the decrease in crystallite size (CS) of the LCMO phase. When plotting LFMR at (77 K, 0.5 T) vs. 1/CS, we find that the data for the LCMO/Mn3O4 composites sintered between 800°C and 1250°C follow the same trend line as data from the literature for pure LCMO samples with crystallite size > ~25 nm. This differs from the LFMR enhancement observed by many authors in the "usual" manganite composites, i.e., composites where the insulating phase contains cations other than La, Ca or Mn. This difference suggests that diffusion of foreign cations into the grain boundary region is a necessary ingredient for the enhanced LFMR. [less ▲]

We report on the crystal structure and electronic bands of LaAu2 and CeAu2 surface intermetallic compounds grown by high-temperature deposition on Au(111). By scanning-tunneling microscopy we study the formation of different alloy phases as a function of growth temperature and lanthanide coverage. We determine the specific growth conditions to achieve monolayers and bilayers of LaAu2 and CeAu2 with high crystalline quality. Due to lattice mismatch with the underlying Au substrate, both LaAu2 and CeAu2 exhibit long-range moire ́ patterns, which can serve as templates for further nanostructure growth. By angle-resolved photoemission we map the two-dimensional band structure of these surface alloys, discussing the nature of the different spectral features in the light of first-principles calculations.
