Calcium phosphate cements (CPCs), using B-tricalcium phosphate (ß-TCP, Ca3 (P04)2), dicalcium phosphate (DCP, CaHP04), calcium carbonate (Ca CO3), and hydroxylapatite (HAp, Ca10(P04)6(OH)2) as powder cement and disodium hydrogen phosphate (Na2HP04) solution as liquid component were prepared. After mixing the powder and liquid constituents, injectable and self-setting calcium phosphate cements (...
In order to study the capability of microalgea Chlorella vulgaris in removal of nitrate and phosphate from water, the effects of initial concentration of nitrate and phosphate and photoperiod were investigated in 20 experiments proposed by response surface methodology. The most effective factors in nitrate removal include initial nitrate concentration, photoperiod and interaction of phosphate-p...
اتصال هگزوکیناز نوع i (i hk ) به میتوکندری بافت های طبیعی و تومورال مغز انسان مورد مطالعه قرار گرفته است . این بررسی با هدف یافتن تفاوت های احتمالی در چگونگی اتصال این آنزیم به غشای خارجی میتوکندری در بافت های مذکور انجام شده و نتایج آن نشان میدهد که مشابه مغز موش صحرایی، دو جایگاه اتصال برای آنزیم hk بر روی میتوکندری مغز انسان وجود دارد، جایگاه حساس به glucose 6-phosphate و جایگاه غیرحساس به آ...
inoculation of phosphate-solubilizing microorganisms along with rock phosphate is known to enhance the available p from soil. the success of such solubilization is largely dependent on the ability of the inoculant strain to survive under adverse environmental conditions. in this context, liquid inoculants are gaining importance and are becoming popular with longer shelf-life. in the present inv...
sised the capacity of the immune system to respond effectively to numerous simultaneous antigens. Using data linkage, Miller et al found no evidence for an increase in admissions to hospital for serious bacterial infections following MMR vaccination. 9 One disadvantage of giving vaccines in combination is that it may not always be clear which component is responsible for a particular adverse ev...
some kinetic properties of nad+- and nadp+- dependent glucose 6-phosphatedehydrogenase (g6pd) purified from streptomyces aureofaciens were studied. both nadh andnadph inhibited the enzyme competitively and noncompetitively, with respect to the correspondingcoenzymes and glucose 6-phosphate, respectively. atp inhibited the nad+ - linked reaction but not thatof the nadp+- linked activity. the inh...
the voltammetric behaviour of sulfadoxine (sdn) was studied at a glassy carbon electrode in 0.2 m phosphate buffer solutions using cyclic, differential-pulse (dpv) and square wave voltammetry (swv). the dependence of the current on ph, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of sdn. the oxidation process was shown to be diffusi...
in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...
Background: Phosphorus is an indispensable element for the growth of animals and plants. There are several environmental problems related to phosphate; therefore, the technical and economic methods of removing phosphate are of great importance. This study evaluated the efficiency of polyaniline/Ni0.5Zn0.5Fe2O4 magnetic nanocomposite in removing phosphate from aqueous environments. Methods: The...
OBJECTIVES The objectives of this study were (1) to determine the safety and immunogenicity of heptavalent pneumococcal CRM197 conjugate (PNCRM7) vaccine in infants and (2) to determine the effect of concurrent hepatitis B immunization during the primary series and the effect of concurrent diphtheria and tetanus toxoid and acellular pertussis [DTaP (ACEL-IMUNE)] and conjugate CRM197 Haemophilus...
