Background: The metabolic syndrome (MS) is a group of cardiovascular risk factors whose prevalence is increased in rheumatic diseases. The aim of this study was to estimate de prevalence of MS and insulin resistance (IR) in systemic sclerosis (SSc).
Methods: Fifty five patients with SSc were included. The World Health Organization criteria were used to define MS. Demographic, anthropometric and blood pressure data were recorded. Blood glucose, high density lipoprotein cholesterol (HDL-c), triglycerides and insulin were measured. Oral glucose tolerance curve was performed to identify impaired glucose tolerance and diabetes mellitus in those patients with normal fasting blood glucose. The HOMA index was calculated as well as a quantified proteinuria in urine of 24 hours.
Results: The prevalence of MS was 36.4 % (20 of 55 patients). Seventy percent of the patients with MS had limited SSc and 30 % diffuse SSc. An increased IR was observed in the limited SSc in comparison with the diffuse SSc (2.948 vs. 1.817 ± 0.3844 ± 0.2771, p = 0.03). An association between IR and MS was found in the limited SSc (p = 0.0001). Regarding the rest of the MS criteria, hypertriglyceridemia and an abnormal waist/hip ratio were the variables most often encountered, 95 % and 85 % respectively. Fifty percent of MS patients had low levels HDL-c and 40 % of them were hypertensive. None of the patients had proteinuria.
Conclusion: The prevalence of MS in SSc was 36.4 %, similar to the found in other rheumatic diseases, but higher compared to the found in the Mexican population.

Seasonal variations in the environment induce observable changes in the human physiological system and manifest as various clinical symptoms in a specific human population. Our earlier studies predicted four global severe seasonal sensitive comorbid lifestyle diseases (SCLDs), namely, asthma, obesity, hypertension, and fibrosis. Our studies further indicated that the SCLD category of the human population may be maladapted or unacclimatized to seasonal changes.

Traditional sprayers are limited to applying spray mixture solely to the upper surfaces of crops. To overcome this limitation, a variable angle spraying machine (VASM) was designed using a linkage system. This machine enables the adjustment of both the spray position and angle through a single input signal, facilitating multi-directional spraying from the top to the bottom of crops.

Background: Monitoring of measurable residual disease (MRD) requires highly sensitive flow cytometry protocols to provide an accurate prediction of shorter progression-free survival. High assay sensitivity generally requires rapid processing to avoid cell loss from small bone marrow sample volumes, but this requirement conflicts with the need in most clinical cytometry laboratories for long processing and acquisition times, especially when multiple MRD studies coincide on the same day.
Methods: The proposed protocol was applied to 226 human bone marrow and 45 peripheral blood samples submitted for the study of MRD or the detection of rare cells.

Background: Dioscorea polystachya and its closely related species are original plants of the tuber crop "yam", which had been intensively use for medicinal and food purposes and widely cultivated in northern China and its surrounding areas with a long history. Many cultivars of these species are often confused with one another because of similar tuber morphology, however, conventional DNA barcoding faces practical limitations restricting the method to effectively identify closely related species. In addition, phylogenetic relationships among various cultivar groups of Chinese yam (D.
