BACKGROUND The burden of lymphomas on the health care system in Nigeria is enormous. Correct diagnosis and identification of aetiological factor are important steps in reducing this burden. METHODS Eight cases diagnosed as HL within a period of six years at the Obafemi Awolowo University teaching Hospital, Ile-Ife, Nigeria by haematoxylin and eosin (Hand E) only were immunophenotyped using th...

normal 0 false false false en-us x-none ar-sa background: dry weight (dw) is an important concept related to patients undergoing hemodialysis. conventional method seems to be time consuming and operator dependent. bio impedance analysis (bia) is a new and simple method reported to be an accurate way for estimating dw. in this study, we aimed to compare the conventional estimation of dw with mea...

A comprehensive consideration of loading effects is essential to the design/analysis of high-frequency MRI radio frequency (RF) coils. In this study, a hybrid finite difference time domain (FDTD)-method of moments (MoM) simulation method is implemented for the accurate evaluation of RF coil-tissue interaction. Using this approach, the RF coil is modelled using the MoM algorithm, and the biologi...

B. Xu, B. K. Li, S. Crozier, F. Liu, Q. Wei School of Information Technology and Electrical Engineering, The University of Queensland, Brisbane, Queensland, Australia INTRODUCTION: High magnetic field (frequency) MRI technology has brought considerable engineering challenges in the form of ancillary hardware, including RF resonators. Studies in high frequency MRI have shown significant interact...

The isohydricity (pH constancy) as the property referred to mixtures of acids or bases, is illustrated on a simple example of the solutions: HL (C0, mol/L) and HL (C mol/L) mixed according to titrimetric mode (pH titration). A new derivation of the Michałowski formula 1 2 0 10 pK C C C    expressing this property is presented, and its applicability for determination of pK1 = – logK1 value is...

PURPOSE In this study, the authors examined diagnostic and intervention services for children identified with hearing loss (HL) after the newborn period. METHOD The authors compared ages at service delivery and length of delays between service delivery steps for 57 later-identified children with HL and 193 children who referred for assessment from the newborn hearing screen (NHS). For only la...

We describe a very efficient method based on ultrasound RF time series analysis and support vector machine classification for generating probabilistic prostate cancer colormaps to augment the biopsy process. To form the RF time series, we continuously record ultrasound RF echoes backscattered from tissue while the imaging probe and the tissue are stationary in position. In an in-vitro study inv...

PURPOSE To determine the effect of hearing loss (HL) on children's performance for an auditory task under demanding listening conditions and to determine the effect of digital noise reduction (DNR) on that performance. METHOD Fifty children with normal hearing (NH) and 30 children with HL (8-12 years of age) categorized words in the presence of auditory or visual competitors, or both. Stimuli...

The human telomere repeat sequence 5'-TTAGGG-3' is a hot spot for oxidation at guanine, yielding 8-oxo-7,8-dihydroguanine (OG), a biomarker of oxidative stress. Telomere shortening resulting from oxidation will ultimately induce cellular senescence. In this study, α-hemolysin (α-HL) nanopore technology was applied to detect and quantify OG in the human telomeric DNA sequence. This repeat sequen...
