Background: Nodal osteoarthritis is one of the most common arthropathy worldwide, the etiology is uncertain but many biochemical markers are recognized. Many studies have shown that leptin might have a role in the pathogenesis of osteoarthritis, but little is known about the relation between serum leptin and nodal osteoarthritis.
Subjects and method: 52 women with nodal osteoarthritis and 40 apparently healthy women as a control were included in the study; serum leptin was measured in all subjects. Student t-test was applied to find out the significance of difference in the mean v
Results: There was a significant difference in the mean of serum leptin between patients and control groups.
Conclusion: the results of the current study suggest that leptin might have a role in the pathogenesis of nodal osteoarthritis
The existing investigation explains the consequence of irradiation of violet laser on the structure properties of MawsoniteCu6Fe2SnS8 [CFTS] thin films. The film was equipped by the utilization of semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser. when the received films were processed by continuous red laser (700 nm) with power (>1000mW) for different laser irradiation time using different number of times a laser scan (0, 6, 9, 12, 15 and 18 times) with total irradiation time (0,30,45,60,75,90 min) respectively at room temperature.. The XRD diffraction gave polycrysta

The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. I
