In this paper we consider the influence of the concentration of oxalate ions and L-aspartic acid on the crystallization of calcium oxalate monohydrate — one of the main components of pathogenic minerals that are included in the composition of kidney stone humans. Crystallization of calcium oxalate was carried out from a model solution, the composition of which was close to the physiological solution...
We propose here derivation algorithms for physiological parameters like beat start point, systolic peak, pulse duration, peak-to-peak distance related to heart rate, dicrotic minima, diastolic peak from Photoplethysmogram (PPG) signals robustly. Our methods are based on unsupervised learning mainly following morphology as well as discrete nature of the signal. Statistical learning has been used as...
Cellular morphology is widely applied in digital pathology and is essential for improving our understanding of the basic physiological processes of organisms. One of the main issues of application is to develop efficient methods for cell deformation measurement. We propose an innovative indirect approach to analyze dynamic cell morphology in image sequences. The proposed approach considers both the...
Podocytes are the mature glomerular epithelial cells that processes highly branched architecture essential for glomerular filtration in the kidney. To resemble the filtration barrier in vivo, we use porous membranes in podocyte culture to mimic the glomerular basement membrane. We found that the morphology of the podocytes were dependent on pore sizes and membrane material. Podocytes grew on anodic...
Phosphorus deficiency was induced in sugar beet plants (Beta Vulgaris L., ‘var. 14’, ‘var. 17’ and ‘var. 20’ with different resistance ability to phosphorus stress), cultured hydroponically and sandily under standardized environmental conditions, by removing phosphorus from the nutrient supply at the seedling stage. Root morphology, H+ excretion and organic acid in rhizosphere were investigated. The...
Somatic embryos were induced from cotyledon explants cultured on MS medium supplemented with 1.0 mg·L−1 2,4-D. Morphological and protein changes were performed aiming at the developmental process of somatic embryogenesis of E. sativa. The observation revealed that the embryos pass through the characteristic globular, heart, torpedo, and cotyledon stages. The developmental process of the somatic embryo...
We report an approach to estimate the functional connection from the possible anatomical connections and physiological response of each neuron. Here we focus on the brain of Bombyx mori, a male silkmoth, which exhibits a programmed behavior for the pheromone orientation on a pheromone detection. The neuroethological experiments revealed that the motor command is generated in the premotor center, composed...
Simultaneous seismocardiogram (SCG) and ultra-low frequency ballistocardiogram (BCG) signals are recorded. Preliminary results from the BCG helped tag which waves on the SCG are related to the rapid systolic ejection and aortic valve closure events. These results agreed with and further confirmed previous findings using the echocardiogram. This is the first reported work on comparisons of SCG and...
