The purpose of this study is to accurately and effectively automate the calculation of the water-equivalent diameter (DW) from 3D CT images for estimating the size-specific dose. DW is the metric that characterizes the patient size and attenuation. In this study, DW was calculated for standard CTDI phantoms and patient images. Two types of phantom were used, one representing the head with a dia...

Overhydration is an independent predictor of mortality in hemodialysis (HD) patients. More than 30% of HD patients are overhydrated, motivating the development of new methods for assessing hydration status. This study surveyed clinical praxis and local guidelines for dry weight (DW) assessment in Swedish and Danish HD units, and examined if differences in routines and utilization of bioimpedanc...

Mushrooms are included in the category of functional foods due to their culinary and pharmaceutical properties. In the present investigation, three wild edible mushrooms including Calocybe gambosa (Fr.) Donk (PUN 3538), Lentinus squarrosulus Mont. (PUN 3539), and Podaxis pistillaris (L.) Fr. (PUN 7151) collected from Haryana (India) were analyzed for their proximate composition and bioactive co...

Introduction The GRASE (GRadient And Spin Echo) pulse sequence was proposed about two decades ago for T2-weighted imaging. GRASE suffers however from image ghosting due to the T2-modulation of the data. A vertical GRASE pulse sequence (vGRASE) was for that reason later introduced by Oshio, in which the EPI trains, following each RF echo, were modified to cover each a vertical instead of a horiz...

Fig. 3. DWSI of rat brain using (a) DW-EPSI and (b) DW-LSEPSI. The left images show NAA maps and the right graphs show average spectra in the red rectangles in the left images. Yellow lines in the left images show edges of a rat head. (c) ADC map of NAA using DW-LSEPSI. Color represents ADC value. Fig. 1. Sequence diagram of DW-LSEPSI. Diffusion-weighted Line-scan Echo-planar Spectroscopic Imag...

Enhanced glucose flux via the hexosamine biosynthesis pathway (HNSP) has been implicated in insulin resistance. We measuredl-glutamine:d-fructose-6-phosphate amidotransferase activity (GFAT, a rate-limiting enzyme) and concentrations of UDP- N-acetyl hexosamines (UDP-HexNAc, major products of HNSP) in muscle and liver of growth hormone (GH)-deficient male dwarf (dw) rats. All parameters measure...

Synthesis of single-wavelength temporal phase-shifting algorithms (PSA) for interferometry is well-known and firmly based on the frequency transfer function (FTF) paradigm. Here we extend the single-wavelength FTF-theory to dual and multi-wavelength PSA-synthesis when several simultaneous laser-colors are present. The FTF-based synthesis for dual-wavelength (DW) PSA is optimized for high signal...

 Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...
