The existence and uniqueness (up to equivalence defined below) of code loops was first established by R. Griess in [3]. Nevertheless, the explicit construction of code loops remained open until T.Hsu introduced the notion of symplectic cubic spaces and their Frattini extensions, and pointed out how the construction of code loops followed from the (purely combinatorial) result of O. Chein and E....

Nitrate is the main form of dissolved inorganic nitrogen, playing an important role in both marine biogeochemical research and water environment management. In this work, most commonly used coppered cadmium column was modified a novel on-line Cu/Cd with spiral structure coupled de-bubbling device syringe-type filter developed. With advantages convenience, portability, stability, high reduction ...

Visceral leishmaniasis (VL), the second-most-serious parasitic illness after malaria, is currently endemic in more than 88 countries. Need for new anti-leishmanial compounds being taken into consideration by researchers due to resistance and lack of effective vaccinations. This research was conducted find out about effect artemisinin (ART). ART examined vitro promastigotes stages ex vivo amasti...

Astaxanthin and tocotrienols, known as antioxidants derived from natural compounds shown to have anti-inflammatory properties. This study aims investigate the effects of a combination astaxanthin extracted Hematococcus pluvialis microalga palm tocotrienols rich-fraction (TRF) on inflammatory reaction in lipopolysaccharide (LPS)-stimulated mouse RAW 264.7 macrophages cells. MTT assay was used te...

Abstract This study aimed at preparing and characterizing thymol, eugenol, piperine-loaded poly(D,L-lactic-co-glycolic acid) nanoparticles evaluating the effect on inflammatory mediators secretion apoptosis in Raw 264.7 macrophage cells. Nanoparticles were produced by solvent evaporation technique. Dynamic light scattering scanning electron microscopy used to physicochemical characteristics. ce...

Featured article: Moshage H, Kok B, Huizenga JR, Jansen PLM. Nitrite and nitrate determinations in plasma: a critical evaluation. Clin Chem 1995;41: 892– 6. The history of nitric oxide (NO•) is a remarkable one. In the early 1980s it was established that nitric oxide was produced in the human body. Shortly afterward it became clear that nitric oxide had important functions in the regulation of ...

various polymorphisms on endothelial nitric oxide synthase (enos) gene cause reduced production of no, the endothelial relaxing factor, and may accelerate the process of atherosclerosis. the study designed to investigate the frequency of t-786c polymorphism of the enos gene in patients suffering from coronary artery disease (cad) in north-west of iran. one hundred twenty subjects including 60 p...

Stress and chronic pain have been shown to prevent the development of tolerance to morphine analgesia, which appears to be related to neuroendocrine activity and alternation in neurochemicals. Also the involvement of nitric oxide (NO) has been implicated in tolerance to morphine analgesia. In our pervious study, we showed that co-administration of swim stress (ss) with chronic morphine, prevent...

Introduction: Cigarette smoking affects nitric oxide production. The aim of this study was to determine associations between tobacco smoke and serum nitric oxide metabolites (NOx) concentration. Methods: Serum NOx concentration was measured by the Griess method in 230 nonsmokers, 238 active, 196 passive and 29 waterpipe smokers. Subjects were selected from participants of Tehran Lipid and Gl...

Our previous studies revealed that echinocystic acid (EA) showed obvious attenuation of atherosclerosis in rabbits fed a high-fat diet. However, the underlying mechanisms remain to be elucidated. Considering importance endothelial progenitor cells (EPCs) atherosclerosis, we hypothesise EPCs may one targets for anti-atherosclerotic potential EA.After vitro cultivation, were exposed 100 μg/mL oxi...
