The cations and anions of the chiral title compound, C(5)H(14)N(2) (2+)·2Cl(-)·0.42H(2)O, are linked by N-H⋯Cl hydrogen bonds into chains propagating in [100], which contain R(4) (2)(14) loops.
Measurement of 226-Ra, 232-Th, 40-K and 137-Cs concentrations in sediment samples determination annual effective dose due to these radionuclides vicinity hot springs Kerman Province
Background and purpose:Rheumatoid arthritis (RA) is an autoimmune-inflammatory disease that may lead to joint destruction and disability. The purpose of this study was to evaluate the influence of life style, reproduction, and some external factors on the development of rheumatoid arthritis. Materials and methods:This is a case-control study, comprised of 184 cases and 184 controls. Possible...
The residence time of fluids circulating through deep-sea hydrothermal systems influences the extent water-rock reactions and flux major minor elements to ocean. While fluid times in numerous basaltic gabbroic have been determined, those less studied ultramafic are currently unknown. Fluids that interact with mantle rocks fundamentally different chemistries therefore unique on seawater chemistr...
Gout and rheumatoid arthritis (RA) are relatively common diseases however, the coexistence of these two conditions has been rarely reported. The author presents a case that was followed for 20 years as RA and gout was also diagnosed based on nodular lesion on feet joints, tap nodules and noticing crystals of uric acid in synovial fluid. In RA patients with severe joint swelling, physicians shou...
بیماری قلبی-عروقی آترواسکلروتیک، علت اصلی مرگ بیماران آرتریت روماتوئید (ra) است. تعداد زیادی از فاکتورهای خطر سنتی (traditional) بیماری قلبی عروقی در ra افزایش یافته اند. این مطالعه به بررسی شیوع ریسک فاکتورهای سنتی بیماری های قلبی-عروقی در بیماران مبتلا به ra مراجعه کننده به درمانگاه های شهر اراک می پردازد.
Background: Rheumatoid arthritis (RA) is the most common inflammatory arthritis affecting 0.5 to 1% of the general population worldwide. The cause of RA remains unknown. In active RA, bone turnover markers change in serum and urine before the appearance of erosions in radiography. In this study, we compared RA activity index with bone turnover marker levels in serum of RA patients. Methods:...
Introduction: Methamphetamine (MA) acts as a powerful oxidant agent, while Rosmarinic Acid (RA) is an effective herbal antioxidant. Oxidative stress-mediated by MA results in apoptosis, and caspase-3 is one of the critical enzymes in the apoptosis process. MA can epigenetically alter gene regulation. In this paper, to investigate the effects of RA on MA-mediated oxidative stress, changes in the...
Investigations conducted during the GEOSECS program concluded that radium-226 (T 1/2 = 1602 y) and barium are tightly correlated in waters above 2500 m Atlantic, Pacific Antarctic Oceans, with a fairly uniform 226 Ra/Ba ratio of 2.3 ± 0.2 dpm µmol -1 (4.6 nmol Ra/mol Ba). Here, we report new Ra Ba data obtained at three different stations Ocean: K1 K3 North-West station old Hale Aloha, off Hawa...
