In this work, we study the lepton-number-violating processes of $K^\pm$ and $D^\pm$ mesons. Two quasi-degenerate sterile neutrinos are assumed to induce such processes. Different with case where only one neutrino involves, here, CP phases mixing parameters could give sizable contribution. This, in turn, would affect absolute values determined by experimental upper limits branching fractions. A ...

Let F be a fully nonlinear second-order partial differential subequation of degenerate elliptic type on a manifold X. We study the question: Which closed subsets E ⊂ X have the property that every F -subharmonic function (subsolution) on X − E, which is locally bounded across E, extends to an F -subharmonic function on X. We also study the related question for F harmonic functions (solutions) w...

Although signals for vacuolar sorting of soluble proteins are well described, we have yet to learn how the plant vacuolar sorting receptor BP80 reaches its correct destination and recycles. To shed light on receptor targeting, we used an in vivo competition assay in which a truncated receptor (green fluorescent protein-BP80) specifically competes with sorting machinery and causes hypersecretion...

Exposure to particulate matter (PM) in ambient air has been shown to lead to adverse health consequences. Six size fractions of PM with aerodynamic diameter smaller than 10μm (PM10) and gas phase were collected at six localities with different major pollution sources. Extracts of samples were assessed for AhR-mediated toxicity, (anti-)estrogenicity, (anti-)androgenicity and genotoxicity. The bi...

A common procedure in Multi-Criteria Decision Analysis is pairwise comparison of alternatives with respect to some criteria. The result of this comparison, whether exact or subjective, is a weight associated to the pair of alternatives measured on some scales. Some authors organize their results in pairwise comparison matrix as a base for further calculation. Potential Method (PM), introduced h...

Epidemiological studies show a strong association between exposure to air pollution – and particularly particulate matter (PM) -, increased prevalence of Multiple Sclerosis (MS) higher rates hospital admissions for MS relapses. Besides having immunomodulatory effects sustaining systemic oxidative-inflammatory response, PM may participate in pathogenesis by targeting also Central Nervous System ...

BACKGROUND AND OBJECTIVE Vitamin B(6) plays a pivotal role in brain development and functioning. Differences in vitamin B(6) homeostasis between preterm and term newborn infants have been reported. The authors sought to investigate whether B(6) vitamers in cerebrospinal fluid (CSF) of preterm and term newborn infants are different. METHODS B(6) vitamer concentrations were determined in 69 CSF...

Introduction: It is frequent in medical practice to have findings with normal aspects in histological muscle biopsies from patients with dermatomyositis (DM) or polymyositis (PM). This happens because, for example, the inflammatory infiltrate occurs in foci. Objectives: To evaluate the morphological and histological inflammatory infiltrate in various histological section levels. In addition, to...
