Carbonates from approximately 2.3-2.1 billion years ago show markedly positive δ(13)C values commonly reaching and sometimes exceeding +10‰. Traditional interpretation of these positive δ(13)C values favors greatly enhanced organic carbon burial on a global scale, although other researchers have invoked widespread methanogenesis within the sediments. To resolve between these competing models an...

BACKGROUND Glucosamine may be effective in treating and possibly slowing the progression of Osteoarthritis (OA). It is believed Glucosamine supplements may help to stop cartilage breakdown, build cartilage and decrease swelling. OBJECTIVE The objective of this study was glucosamine sulfate versus combination of glucosamine sulfate and Non-Steroidal anti-inflammatory drugs (NSAID) in mild to m...

the purpose of this research was to design a semi-industrial culture medium to obtain the maximum biomass production from bacterium bacillus subtilis utb96. in the first step, in order to reduce the cost of culture medium components, commercial products and industrial by products including, sugar beet molasses, sugar cane molasses, potato waste water and milk serum as carbon sources and corn st...

Background: Previous studies have shown that magnesium sulfate (MgSO4) administered in a patient with a diffuse axonal injury (DAI) can serve as a useful neuroprotective agent. The present study was conducted to examine whether magnesium sulfate has a therapeutic efficacy and safety in patients with a severe diffuse axonal injury. Methods: Adult patients admitted within 1 hour of a closed Traum...

Background and Aim. Aparallel, randomized, double blinded, placebo-controlled trial study was designed to assess the efficacy of single low dose of intravenous magnesium sulfate on post-total abdominal hysterectomy (TAH) pain relief under balanced general anesthesia. Subject and Methods. Forty women undergoing TAH surgery were assigned to two magnesium sulfate (N = 20) and normal saline (N = 20...

purpose: propofol is one of the most common drugs used in anesthesia induction and the pain during its intravenous injection is one of the most important side effectsthat it has. therefore, many methods and drugs have been examined so far to reduce or eliminate this side effect. in this study a lot the effects of alfentanil, magnesium sulfate and ketamine drugs on reducing the pain during intra...

OBJECTIVE The relationship between clinicalfeatures and biochemical parameters of synovialfluid after serial intra-articular injections of sodium hyaluronate (SI-6601D) was investigated. METHODS SI-6601D (sodium hyaluronate with an average molecular weight of 8.4 x 10(5); 25mg/2.5ml/syringe) was injected intra-articularly into the knees of 25 patients with rheumatoid arthritis (RA) every week...

BACKGROUND We report on a controlled trial of a mixed amphetamine salts compound (Adderall, dextroamphetamine sulfate, dextro-, levoamphetamine sulfate, dextroamphetamine aspartate, levoamphetamine aspartate, and dextroamphetamine saccharate) in the treatment of adult attention-deficit/hyperactivity disorder (ADHD). METHODS This was a 7-week, randomized, double-blind, placebo-controlled, cros...

Carboxymethyl-quaternized oligochitosan (CMQAOC) was prepared through carboxymethylization and N-quaternization of oligochitosan (OC) which was obtained from chitosan degradation. The structure was confirmed by Fourier transform infrared spectroscopy (FT-IR), H-NMR, and X-ray diffraction (XRD) analysis. The performances for both scale and microbial inhibition of CMQAOC were evaluated by static ...
