Seleno-enzymes and seleno-compounds: the two faces of selenium
Selenium protects cells and inhibits many inflammatory cell mechanisms through antioxidant seleno-enzymes. Immunity improvement is illustrated by the study of Berger and colleagues, with reduction of nosocomial pneumonia in burnt patients under multi-trace-element supplementation. As seleno-compounds (especially sodium selenite) are pro-oxidant, however, administration above 800 microg/day may ...
متن کاملTwo Faces of SIVA.
In non-small cell lung cancer cells that contain a mutated KRAS gene, SIVA, a p53 target gene that is critical for apoptosis, is overexpressed in a p53-independent manner and promotes tumorigenesis through the stimulation of mTOR signaling. The ablation of Siva in conditional knockout mice results in an inhibition of tumor development that makes SIVA an interesting new candidate therapeutic tar...
متن کاملTwo faces of narcissism.
The present study examines the lack of strong correlations among existing self-report measures of narcissism. A principal-components analysis of 6 MMPI narcissism scales resulted in 2 orthogonal factors, 1 implying Vulnerability-Sensitivity and the other Grandiosity-Exhibitionism. Although unrelated to each other, these 2 factors were associated with such core features of narcissism as conceit,...
متن کاملAn Enhanced Finite Element method for Two Dimensional Linear Viscoelasticity using Complex Fourier Elements
In this paper, the finite element analysis of two-dimensional linear viscoelastic problems is performed using quadrilateral complex Fourier elements and, the results are compared with those obtained by quadrilateral classic Lagrange elements. Complex Fourier shape functions contain a shape parameter which is a constant unknown parameter adopted to enhance approximation’s accuracy. Since the iso...
متن کاملPorokeratosis: Two Faces, One Family
Porokeratosis is a disorder of keratinisation whose pathogenesis is yet unclear. It has been postulated that it results from the proliferation of an abnormal clone of keratinocytes, triggered by several factors, such as immunosuppression or prolonged ultraviolet exposure. Various clinical forms are recognized whose common denominator is a keratotic ring surrounding a central zone of atrophy. Th...
