Spent or disused sealed radiation sources—no longer needed sources—may represent a risk of radiological accident or may be a target for criminal acts in countries where final disposal options are unavailable and where an increasing number of sources are being kept in extended storage. In developing countries, thousands of radium needles, teletherapy sources, oil well logging neutron sources, an...
The adsorption and desorption of paraquat (1, l'-dimethyl-4,4'-dipyridylium dichloride) in two tropical soils was determined under laboratory conditions. The two soils were taken from rice fields located in the North West of Perak state. The adsorption equilibrium time was 2 hours for both soil types. This adsorption equilibrium time was used to determine the effect of concentration on adsorpti...
The reaction of MgCl(2), NiCl(2), and Na(2)(i-mnt) (i-mnt is 1,1-dicyano-thene-2,2-dithiol-ate) with 15-crown-5 (15-C-5) leads to an infinite chain polymer, {[NiMg(2)(C(4)N(2)S(2))(2)(C(10)H(20)O(5))(2)]Cl(2)}(n) or {[Mg(15-C-5)](2)[Ni(i-mnt)(2)]Cl(2)}(n), which consists of two [Mg(15-C-5)](2+) complex cations, one [Ni(i-mnt)(2)](2-) complex anion and two Cl(-) ions per formula unit. In the [Ni...
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...
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...
It is believed that therapy for rheumatoid arthritis (RA) is the most effective and beneficial within a short time frame around RA diagnosis. This insight has caused a shift from research in patients with established RA to patients at risk of developing RA and recently diagnosed patients. It is important for improvement of RA therapy to understand when and what changes occur in patients develop...
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:...
