Objective(s): This study was undertaken to determine the role of computed tomography (CT)-based methodology to segment the SI joint and quantify the metabolic activity using positron emission tomography (PET). We measured tracer uptake in the right and left SI joints independently to look for differences between the two sides. Further, we correlated tracer uptake with ...
Background and Objectives: Metabolic syndrome (MetS) is one of the most common diseases and a public health problem in most populations and predisposes to many metabolic disorders such as type 2 diabetes. Inflammatory processes and oxidative stress are the important factors in pathogenesis of MetS. Also, the effect of sex, race, age, nutrition and life style is very important in incidence of th...
Regular physical activity (PA) and healthy nutrition are effective strategies to improve crucial modifiable lifestyle factors that affect health status, both in people special populations suffering from metabolic disorders [...]
fructose consumption has increased dramatically in the last 40 years, and its role in the pathogenesis of the metabolic syndrome has been implicated by many studies. it is most often encountered in the diet as sucrose (glucose and fructose) or high-fructose corn syrup (55% fructose). at high levels, dietary exposure to fructose triggers a series of metabolic changes originating in the liver, le...
The production of reactive oxygen species occurs during the natural metabolism of oxidative-breathing cells. Among reactive oxygen species, hydrogen peroxide is more dangerous to cell life due to its long half-life, but it is meanwhile an important regulatory molecule in redox signaling in living things. Peroxidases are one of the key antioxidant enzymes that are widely distributed in nature an...
The 2017 Nobel Prize for medicine was awarded the biological clock Scientist, which shows the importance of this phenomenon in the life of living organisms. The circadian Rhythm (CR) through the created internal “clock” is responsible for regulating the daily performance of different organs of the body. The central body clock is the key factor to creating and maintaining this CR. External optic...
OBJECTIVE We examined the associations of objectively measured sedentary time and physical activity with continuous indexes of metabolic risk in Australian adults without known diabetes. RESEARCH DESIGN AND METHODS An accelerometer was used to derive the percentage of monitoring time spent sedentary and in light-intensity and moderate-to-vigorous-intensity activity, as well as mean activity i...
Phase contrast microscopy cannot give sufficient information on bacterial metabolic activity, or if a cell is dead, it has the fate to die or it is in a viable but non-growing state. Thus, a reliable sensing of the metabolic activity helps to distinguish different categories of viability. We present a non-invasive instantaneous sensing method using a fluorogenic substrate for online monitoring ...
Objective(s): Functional imaging presents a non-invasive process that may capture the hyper-metabolic nature of red bone marrow in myeloproliferative neoplasms, such as polycythemia vera (PV). Methods: This study analyzed the FDG-PET/CT scans (n=12) of six patients diagnosed with PV and six age-sex matched controls using a quantitative global analysis methodol...
To investigate the cytotoxicity mechanism of quinocetone from the perspective of chemical structure, quinocetone and other new quinoxaline-1,4-dioxide derivatives were synthesized, and evaluated for their activities, and analysed for the metabolic characteristics. Quinocetone and other new quinoxaline-1,4-dioxide derivatives were synthesized, and evaluated for their activities, and analysed for...
