INTRODUCTION Low vitamin D (VD) is associated with secondary hyperparathyroidism and both contribute to deleterious consequences (reduced bone mineral density (BMD), risk of fractures and falls). OBJECTIVE To study the VD status and biological correlates in a group of postmenopausal women. MATERIAL AND METHODS We studied 123 postmenopausal women evaluated in the C.I.Parhon National Institut...

BACKGROUND Choroidal thickness (CTh) and choroidal vessel diameter (VD) in the Haler's layer were evaluated as markers of inflammatory insult in non-infectious uveitis (NIU). Spectral-domain optical coherence tomography (Spectralis®, Heidelberg Engineering Inc.) scans were acquired from 23 normal subjects (39 eyes - group 1), 7 subjects with high myopia (14 eyes - group 2), and 19 patients with...

OBJECTIVE Two methods of quantitating cerebral blood flow (CBF) with iodine-123-labeled N-isopropyl-p-iodoamphetamine (I-123 IMP) and a two-compartment model had been proposed; one is the table look-up (TLU) method and the other is the autoradiographic (ARG) method. The TLU method provides values of the cerebral blood flow (CBF) values and distribution volume of I-123 IMP (Vd) independently. In...

BACKGROUND Depression is the most widely acknowledged psychological problem among end-stage renal disease (ESRD) patients. Depression may be associated with VD deficiency. The aims of this study are to (a) elucidate the prospective association between HsCRP, VD contents and depressive symptoms in the dialyzed population, and (b) find the effect of calcitriol supplementation on depression in dia...

We identified a novel Drosophila protein of approximately 400 kDa, hemolectin (d-Hml), secreted from haemocyte-derived Kc167 cells. Its 11.7 kbp cDNA contains an open reading frame of 3843 amino acid residues, with conserved domains in von Willebrand factor (VWF), coagulation factor V/VIII and complement factors. The d-hml gene is located on the third chromosome (position 70C1-5) and consists o...

BACKGROUND The dead-space volume (VD) of face masks for metered-dose inhaler treatments is particularly important in infants and young children with asthma, who have relatively low tidal volumes. Data about VD have been traditionally obtained from water displacement measurements, in which masks are held against a flat surface. Because, in real life, masks are placed against the face, VD is like...

INTRODUCTION Dead-space fraction (Vd/Vt) has been shown to be a powerful predictor of mortality in acute lung injury (ALI) patients. The measurement of Vd/Vt is based on the analysis of expired CO2 which is not a part of standard practice thus limiting widespread clinical application of this method. The objective of this study was to determine prognostic value of Vd/Vt estimated from routinely ...

In this paper, we propose a novel single-electron device for computation of a Voronoi diagram (VD). A cellular-automaton model of VD formation [18] was used to construct the device that consisted of three layers of a 2-D array of single-electron oscillators. Through extensive numerical simulations, we show pattern formation on the proposed device and demonstrate the VD computation.

Let VD be the Shimura curve over Q attached to the indefinite rational quaternion algebra of discriminant D. In this note we investigate the group of automorphisms of VD and prove that, in many cases, it is the Atkin–Lehner group. Moreover, we determine the family of bielliptic Shimura curves ðover Q and over QÞ and we use it to study the set of rational points on VD over quadratic fields. Fina...
