OBJECTIVE To evaluate clinical 3.0T magnetic resonance for tracking and quantifying superparamagnetic iron oxide (SPIO)-labeled endothelial progenitor cells (EPCs) in vitro and homing to liver with acute injury in vivo. METHODS The bone marrow-derived EPCs were isolated and cultured for 4 days and examined in vitro for lineage markers. Then the cultured cells were labeled with a ferumoxides-p...

Although administration of the vascular endothelial growth factor (VEGF), a potent angiogenic factor, could improve the overall survival of destroyed sinusoidal endothelial cells (SEC) in chemically induced murine acute hepatic failure (AHF), the mechanistic roles of the VEGF receptors have not been elucidated yet. The respective roles of VEGF receptors; namely, Flt-1 (VEGFR-1: R1) and KDR/Flk-...

A classical result states that every lower bounded superharmonic function on R2 is constant. In this paper the following (stronger) one-circle version is proven. If f : R2 → (−∞,∞] is lower semicontinuous, lim inf |x|→∞ f(x)/ ln |x| ≥ 0, and, for every x ∈ R2, 1/(2π) ∫ 2π 0 f(x + r(x)e) dt ≤ f(x), where r : R2 → (0,∞) is continuous, supx∈R2(r(x) − |x|) < ∞, and infx∈R2(r(x) − |x|) = −∞, then f ...

The aim of the present study was to investigate lower limb anthropometric and composition variables related to running economy (RE) and running performance in a homogeneous group of high level European distance runners. RE at the speeds of 14, 16 and 18 km·h-1 (189 ± 12; 188 ± 11; 187 ± 11 O2 ml·kg-1·km-1) and maximal oxygen uptake (VO2max) (67.3 ± 2.9 ml·kg-1·min-1) of 13 high level distance r...

A bstract The exchange of a pair neutrinos between two objects, seperated by distance r , leads to long-range effective potential proportional 1 /r 5 assuming massless and four-fermion contact interactions. In this paper, we investigate how known form neutrino-mediated potentials might be altered if the is sufficiently short, corresponding large momentum transfer which could invalidate We consi...

Mapping cerebrovascular reactivity (CVR) to hypercapnia is important both clinically and for improved understanding of the haemodynamic properties of the BOLD effect. In this work, BOLD/R2 CVR was investigated by using a device which provided small, repeatable and stable steps in PETCO2, whilst maintaining a steady PETO2 level. Significant CVR was observed in both grey and white matter at both ...

H. Steinhaus has asked whether inside each acute triangle there is a point from which perpendiculars to the sides divide the triangle into three parts of equal areas. We present two solutions of Steinhaus’ problem. The n-dimensional case of Theorem 1 below was proved in [6], see also [2] and [4, Theorem 2.1, p. 152]. For an earlier mass-partition version of Theorem 1, for bounded convex masses ...
