This paper reports the optimisation of the low-frequency response of a multi-stage bioelectric amplifier intended for use in the measurement of the electrocardiogram (ECG) using un-gelled electrodes. The frequency response was optimised to meet the International Electrotechnical Commission 60601 performance standards for electrocardiographs [1,2]. The low frequency response of a multi-stage amp...

Obesity/Overweight is a recognized risk factor for most of the disorders and risk stratification is based on Quetelets index, a surrogate measure of fatness. Currently used body mass index (BMI) cut-offs to classify people as overweight/obese does not accurately represent the BMI cut-offs in Nepalese population, due to differences in body structure and composition. This study was conducted to d...

BACKGROUND Weight gain during the childbearing years and failure to lose pregnancy weight after birth contribute to the development of obesity in postpartum Latinas. METHODS Madres para la Salud [Mothers for Health] was a 12-month, randomized controlled trial exploring a social support intervention with moderate-intensity physical activity (PA) seeking to effect changes in body fat, fat tissu...

Body hydration and extra- to intra-cellular water ratio (ECW: ICW) have been studied in 12 duchenne muscular dystrophy (DMD) patients and 15 healthy controls. Subjects underwent total body water (TBW) and extracellular water (ECW) assessment by deuterium and bromide dilution, respectively. Multifrequency bioelectric impedance analysis (MFBIA) was performed on all subjects with the aim to establ...

BACKGROUND--Bronchial epithelial function after heart-lung transplantation (HLT) for cystic fibrosis (CF) may be affected by the original disease as well as other factors such as prolonged organ ischaemic time, the interruption of bronchial arterial and lymphatic supply, infection, rejection, and cyclosporin. In vitro measurement of the bioelectric properties of the bronchial mucosal lining may...

Bacterial biofilms are the primary cause of infections in medical implants and catheters. Delayed detection of biofilm infections contributes to the widespread use of high doses of antibiotics, leading to the emergence of antibiotic-resistant bacterial strains. Accordingly, there is an urgent need for systems that can rapidly detect and treat biofilm infections in situ. As a step toward this go...

OBJECTIVE To assess body composition and lipid profile of women with and without breast cancer. METHODS We conducted a case-control study matched by age, including 62 women, 31 being newly diagnosed with breast cancer and 31 with benign breast changes. Data were collected through direct interview, with recording of sociodemographic characteristics, body composition assessment by anthropometry...

BACKGROUND AND OBJECTIVE Although Asian Indians have been shown to have increased body fat compared to Europeans, there have been very few studies in Asian Indians validating the various methods available for body fat measurement. The aim of this study was to test the validity of body fat measured by two commercial impedance analyzers (leg-to-leg and hand-held) as well as by skinfolds with Dual...
