several recent reports reveal that patients develop symptoms of gastorintestinal motility disorders after the standard whipple procedure. in the department of propedeutics of surgery at bulgarian medical academy in sofia we observed the same phenomenon in our whipple-operated group of patients. but the pathogenetic mechanism was so far unclear that prompted us to conduct an experimental study i...

A hand-held bioelectric impedance device was used to obtain body fat percentages from obese and lean healthy client-owned dogs. Bioelectric impedance values were compared with body condition scores assigned on a 9-point scale during physical examination to evaluate the correlation of these two methods for assessing body composition. A good correlation was revealed between body fat percentage as...

Artifacts in bioelectric signals can make bioelectric signals unreliable. Spectral and temporal overlap can make the removal of artifact or separation of different bioelectric signals extremely difficult. Often, the sources of the bioelectric signals may be considered as independent at the local level and this makes an argument for separating the signals using independent component analysis (IC...

The objective of this study was to evaluate the effect of soil moisture condition and irrigation regime on the bioelectric potential of crops with different growth stages. The bioelectric potential of broccoli (Brassica oleracea var. italica) plants at the initial and mid-growth stages was measured under different soil moisture conditions and irrigation regimes using pot experiments. The result...

Excised root tips from dark-grown mung bean seedlings (Phaseolus aureus) that adhere to a negatively charged glass surface when irradiated with red light and release when irradiated by far-red light develop a positive bioelectric potential (about 1.0 millivolt) at the tip in red light and a negative bioelectric potential in far-red light. The sign of the bioelectric potential was repeatedly pho...

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...

Electromagnetic source localization (ESL) provides non-invasive evaluation of brain electrical activity for neurology research and clinical evaluation of neurological disorders such as epilepsy. Accurate ESL results are dependent upon the use of patient specific models of bioelectric conductivity. While the effects of anisotropic conductivities in the skull and white matter have been previously...

OBJECTIVE The association between rarely used anthropometric measurements (e.g., mid-upper arm, forearm, and calf circumference) and metabolic syndrome has not been proven. The aim of this study was to assess whether mid-upper arm, forearm, calf, and waist circumferences, as well as waist/height ratio and waist-to-hip ratio, were associated with metabolic syndrome. METHODS We enrolled 387 sub...

We describe a sensitive plant monitoring system by the detection of the bioelectric potentials in plants with boron-doped diamond (BDD) electrodes. For sensor electrodes, we used commercially available BDD, Ag, and Pt plate electrodes. We tested this approach on a hybrid species in the genus Opuntia (potted) and three different trees (ground-planted) at different places in Japan. For the Opunti...
