A novel sensor for the determination of warfarin based on a simple and sensitive method was developed on multiwalled-carbon-nanotube modified ZnCrFeO4 carbon paste electrodes（MWCNT/ZnCrFeO4/CPEs）. Cyclic voltammetry, differential pulse voltammetry, chronoamperometry, and electrochemical impedance spectroscopy were used to investigate the electrochemical behavior of warfarin at the chemically modified electrode. According to the results, MWCNT/ZnCrFeO4/CPEs showed high electrocatalytic activity for warfarin oxidation, producing a sharp oxidation peak current at about ＋0.97 vs Ag/AgCl reference electrode at pH = 4.0. The peak current was linearly dependent on warfarin concentration over the range of 0.02–920.0 μmol/L with a detection limit of 0.003 μmol/L. In addition, chronoamperometry was also used to determine warfarin＇s catalytic rate constant and diffusion coefficient at MWCNT/ZnCrFeO4/CPEs.

ObjectiveTo determine the seroprevalence of anti-Toxoplasma gondii (T. gondii) IgG and IgM antibodies in HIV/AIDS patients and uninfected subjects.MethodsThis cross sectional survey was carried out on 78 healthy and 62 HIV+/AIDS individuals in northern Iran between September 2007 and October 2008. Five mL of blood samples were collected from each person in case and control groups. Determination of CD4+ counts was performed by flow cytometry. The serum separated from blood samples was evaluated by conventional ELISA technique to determine the presence of antibodies to T. gondii.ResultsForty eight out of 62 (77.4%) HIV/AIDS serum samples were found positive for anti-T. gondii IgG antibody, compared with 59 among 78 (75.6%) HIV negative samples from the same area (P > 0.05). Six out of 62 (9.7%) HIV+/AIDS patients showed anti-T. gondii IgM antibody in their serum samples, compared with 7 among 78 (9%) HIV negative samples (P > 0.05). The mean of CD4+ counts in HIV+/AIDS was (430.8±182.3) cells/μL and in control group was (871.0±243.3)% cells/μL (P<0.01). CD4+ estimation in 5 (11.1%) of HIV+/AIDS patients was <200 cells/μL (P < 0.0001).ConclusionsSeroprevalence of latent toxoplasmosis in HIV patients is high, therefore the prevention of toxoplasmic encephalitis, administration of primary prophylaxis with co-trimoxazole to all HIV+/AIDS patients are necessary.

In order to investigate the development of forest soils formed on loess, six representative modern soil pedons were selected along a precipitation gradient extending from eastern Golestan(mean annual precipitation, MAP = 500 mm)to eastern Mazandaran Provinces(MAP = 800 mm).Physiochemical, micromorphological and magnetic properties, as well as clay mineralogy of soils were studied using standard methods. Soils are mainly classified as Alfisols and Mollisols. Downward decalcification and the subsequent clay illuviation were the main criteria of soil development in all study areas. Pedogenic magnetic susceptibility of pedons studied varied systematically across the precipitation gradient in Northern Iran, increasing from 14.66 ×10-8 m3 kg-1 at the eastern part to 83.75 × 10-8 m3 kg-1 at the western margin of this transect. The frequencydependent magnetic susceptibility showed an increasing trend with rainfall as well. The micromorphological study of soils indicated that there is a positive relationship between climate gradient (increasing rainfall) and the micromorphological index of soil development(MISECA). The area and thickness of clay coatings showed an increasing trend with rainfall. Grain size analysis indicates that pedogenic processes are responsible for changing original grain size distribution of loess in our *** correlation achieved among modern soil properties and precipitation could be applied to the buried paleosols in the whole study area to refer degree of paleosol development and to reconstruct the paleoclimate.

Objective: The aim of this study was to evaluate the analgesic and anti-inflammatory effects of the hydroalcoholic extracts of Malva sylvestris flowers or Carum carvi and Medicago sativa seeds, alone and in combination, which have been used in traditional Iranian ***: Male Wistar rats were divided into 6 treatment groups: distilled water, sodium salicylate(SS),M. sylvestris extract(600 mg/kg), C. carvi extract(600 mg/kg), M. sativa extract(300 mg/kg) and combined extract(including 300 mg/kg M. sylvestris and C. carvi extracts, and 150 mg/kg M. sativa extract). The formalin pain model was used to evaluate the antinociceptive effects of the treatments. For anti-inflammatory effect, acute(one hour after injection) and chronic(during a week after injection)paw inflammation was measured after subcutaneous injection of 2.5% formalin in the ***, tissue samples from all groups were prepared for histopathological ***: The combined extract significantly inhibited the nociception in the acute phase of the formalin test(P < 0.001). In the chronic phase, all the extracts and SS had significant analgesic effect(P < 0.001).Analgesic activity of the combined extract was significantly stronger than SS(P < 0.01). In the acute inflammation model, M. sylvestris, C. carvi and the combined drug had significant inhibitory effects against paw edema(P < 0.05). All extracts, individually and in combination, significantly alleviated chronic paw inflammation(P < 0.01). The combined extract had much more anti-inflammatory activity than SS(P < 0.05). Histopathological results indicated improvement and reduction of inflammatory factors in the treatment ***: M. sylvestris, C. carvi and M. sativa have analgesic and anti-inflammatory ***, each of these extracts or a mixture of them might be a valuable alternative drug to control pain and inflammation.
