Cortisol is known to be correlated with cognition, aging, and quantitative electroencephalography (QEEG), although these factors have not yet been reported. This study aimed to evaluate an integrated model for estimating cortisol levels in elderly people. Sixty-four participants were included. Saliva cortisol levels were measured by enzyme-linked immunosorbent assay (ELISA). Cognitive function was...
Melatonin and cortisol are the main hormones of the circadian rhythm, which effect cognitive decline during aging. An imbalance of circadian rhythm hormones serves as an early sign of the progress of age-related disease and brain pathology in aging. The aim of this study was to determine the cortisol-melatonin ratio in relation to brain activity and cognitive function in aging. Sixty-four aging subjects...
Since a long time ago, one of a dangerous cancer that threatening human life is pulmonary cancer. Although, an open thoracic surgery is generally realized as a conventional gold standard for this malignant, but a new therapeutic method still be proposed as an alternative choice to deal with this hazard. In this paper, we present a FEM of microwave thermal treatment to ablate cancerous region in a...
The color and light have effect on physiology, psychology, cognitive performance and hormone production in the human. In this paper, we aim to study red and blue color with their effect on brain activity, cardiovascular activity, emotion and saliva hormone. Each participant was testing in red and blue room. Participant was measure the EEG, ECG, SpO2, pulse rate, saliva hormone (melatonin, cortisol,...
Light and color have been shown to have substantial physical, psychological and sociological effects on humans. Hence, an investigation on the effect of changes in light and color to the biological signals is a challenging problem. Five participants were measured the oxygen saturation (SpO2), pulse rate, and quantitative electroencephalogram (QEEG) in six colors (white, blue, green, yellow, red and...
Bone drilling is an important medical maneuver in a general orthopedic surgery. Hole drilling by using a conventional mechanical rotary drill is avoidable for a tiny bone chip and a corrosion of drill bit. An application of microwave energy to drill a hard cortical bone is even though proposed by some researchers but an investigation of thermal interaction at a drill site is still remain promising...
Melatonin is a circadian hormone transmitted via suprachiasmatic nucleus (SCN) in the hypothalamus and sympathetic nervous system to the pineal gland. It is a hormone necessary to many human functions such as immune, cardiovascular, neuron and sleep/awake functions. Since melatonin enhancement or suppression is reported to be closely related to the photic information from retina, in this paper, we...
The purpose of this research was to survey the maintenance systems of medical equipment in four general hospitals in the central region of Thailand under the Ministry of Public Health using the criteria from the medical equipment maintenance standard that is the standard for administrative organizations, human resources, technical equipment, work places, suppliers and stores, maintenance, and quality...
