We study the $\ensuremath{\rho}$ and $\ensuremath{\omega}$ meson contribution to radiative decays $X(3872)\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\pi}\ensuremath{\gamma}$ $X(3872)\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\pi}\ensuremath{\pi}\ensuremath{\gamma}$. The is dominated by meson. As for $X(3872)\ensuremath{\rightarrow}\phantom{\rule{0ex}{0ex}}J/\ensuremath{\...

Objectives: Considerable information exists concerning the differences in motoneuron pool (MP) excitability between young and elderly subjects. A recent study demonstrated decreased heteronymous Ia facilitation with aging, suggesting increased presynaptic inhibition (PI) with increasing age as a mechanism for this change (Morita et al., Exp Brain Res 104 (1995) 167). It has been suggested that ...

BACKGROUND Little is known about whether associations between childhood adiposity and later adverse cardiovascular health outcomes are driven by tracking of overweight from childhood to adulthood and/or by vascular and metabolic changes from childhood overweight that persist into adulthood. Our objective is to characterise associations between trajectories of adiposity across childhood and a wi...

BACKGROUND Dyspnea and fatigue are the main causes of exercise limitation in chronic heart failure (CHF) patients, whose peak inspiratory (Pi(max)) and expiratory pressures (Pe(max)) are often reduced. The aim of this study was to examine the relationship between respiratory muscle performance and oxygen kinetics. METHODS AND RESULTS A total of 55 patients (NYHA class I to III) and 11 healthy...

In this article we demonstrate the performance of a direct conversion amorphous selenium (a-Se) X-ray detector using biphenyldisnhydride/1,4 phenylenediamine (BPDA/PPD) polyimide (PI) as a hole-blocking layer. The use of a PI layer with a-Se allows detector operation at high electric fields (≥10 V/μm) while maintaining low dark current, without deterioration of transient performance. The hole m...

Intranasal administration of peptide Ac1-9[4Y], based on the N-terminal epitope of myelin basic protein, can induce CD4(+) T cell tolerance, and suppress experimental autoimmune encephalomyelitis induction. The peptide-induced regulatory T (PI-T(Reg)) cells failed to produce IL-2, but expressed IL-10 in response to Ag and could suppress naive T cell responses in vitro. Analysis of Jak-STAT sign...

Phytosanitary treatments disinfest traded commodities of potential quarantine pests. Phytosanitary irradiation (PI) treatments use ionizing radiation to accomplish this, and, since their international commercial debut in 2004, the use of this technology has increased by ~10% annually. Generic PI treatments (one dose is used for a group of pests and/or commodities, although not all have been tes...

The monocyte and granulocyte azurophilic granule proteinases elastase, proteinase 3, and cathepsin G are implicated in acute and chronic diseases thought to result from an imbalance between the secreted proteinase(s) and circulating serpins such as alpha1-proteinase inhibitor and alpha1-antichymotrypsin. We show here that the intracellular serpin, proteinase inhibitor 6 (PI-6), is present in mo...

Hyaluronan oligosaccharides (molecular weight: approximately 2.5 x 10(3)) inhibit growth of several types of tumors in vivo. In vitro, the oligomers inhibit anchorage-independent growth of several tumor cell types. In accordance with this finding, the oligomers also induce apoptosis and stimulate caspase-3 activity under anchorage-independent conditions. Since inhibitors of phosphoinositide 3-k...
