Although total limb volume measurements are used to track the progress of lymphedema and its treatment, these measurements can be confounded by changes other than fluid excess namely muscle or fat gain. Bioelectrical impedance analysis (BIA) is a technique that specifically quantifies both total body fluid and extracellular fluid in extremities. Whereas BIA has potential as a quick, inexpensive...

Validation and interpretation of reconstructed images using a multi-frequency electrical impedance tomography (mfEIT) requires a conductivity phantom including imaging objects with known complex conductivity (sigma + iomegaepsilon) spectra. We describe imaging experiments using the recently developed mfEIT system called the KHU Mark1 with the frequency range of 10 Hz to 500 kHz. Using a bio-imp...

Lab-on-a-chip systems have been attracting a growing attention for the perspective of miniaturization and portability of bio-chemical assays. Here we present a the design and characterization of a miniaturized, USB-powered, self-contained, 2-channel instrument for impedance sensing, suitable for label-free tracking and real-time detection of cells flowing in microfluidic channels. This original...

In the previous lecture, we leant about impedance spectroscopy. Electrochemical impedance spectroscopy is the technique where the cell or electrode impedance is platted versus frequency. Thus, the impedance is measured as a function of the frequency of the AC source. Electrochemical impedance spectroscopy is a useful method for investigating porous electrodes, which are extensively used in the ...

BACKGROUND The impedance baseline has been shown to reflect esophageal integrity, and to be decreased in patients with esophagitis. However, different methods for the determination of the impedance baseline have not been compared. METHODS The median impedance baseline was calculated in 10 consecutive multichannel intraluminal impedance recordings in children with non-erosive reflux disease. A...

Introduction: Lower limb lymphedema (LLL) is one of the most disabling side effects surgical and radiotherapy treatment for gynecological cancers (carcinoma cervix, carcinoma ovary, endometrium, vulva). The incidence varies in patients undergoing surgery. This prospective study aims to determine lower after surgery malignancies.Methodology: A total 512 subjects who undergo malignancies departme...
