Zn-Al layered double hydroxide (LDH) nanoparticles with carbonate as the charge balancing anion in the interlayer space were synthesized using co-precipitation method. Then, the carbonate base Zn-Al LDH nanoparticles were doped with phosphate ion via anion-exchange reaction to synthesize Zn-Al-[PO43-]-[CO32-]. The structure and composition were characterized by X-ray diffraction (XRD), Fourier ...

Am J Physiol Cell Physiol 283: C1469–C1479, 2002. First published June 20, 2002; 10.1152/ajpcell.00114.2002.—We evaluated the dependency of neutrophil O2 production on PTK-Lyn and MAPKERK1/2 in rats after thermal inj...

in the present study the distribution of rubella hemagglutination inhibition (hi) antibody titer in the sera of 1486 women of 18 to 25 years old residing in tehran were examined. sera were pretreated with acid washed kaolin and pigeon red blood cell. titers below 1:10 and in some studies below 1:20 are considered nonimmune to rubella. our results show that 10, 29% of studied population had hi a...

Studies have shown that noxious cutaneous stimulation engages physiologically different antinociceptive systems to inhibit a spinal reflex, tail withdrawal from radiant heat. Two experiments are reported that examine the relationship between the inhibition of the tail-flick response and brain-mediated responses to nociception. The induction of a spinally mediated antinociception was accompanied...

BACKGROUND AND METHODS The role of the endogenous purine nucleoside, adenosine, in nociception is well established. Inhibition of the equilibrative nucleoside transporter (ENT1) prevents adenosine uptake into cells, and could therefore enhance the antinociceptive properties of adenosine. The effects of ENT1 inhibition were studied in two animal models of inflammatory pain. Analgesic activity wa...

conclusions all plants could inhibit mushroom tyrosinase, but more investigations on human tyrosinase and clinical studies are needed. results the hydroalcoholic extract of p. alkekengi showed the most tyrosinase inhibitory effect with ic50 of 0.09 mg/ml vs. 0.38, 0.38 and 2.82 mg/ml of b. persicum, a. rosea and m. vulgare, respectively. m. vulgare exhibited uncompetitive inhibition and other p...

background: the current study aimed to determine the effect and properties of surface-modified copper doped cu:zno nps on killing curves of bacterial pathogens. m ethods:   preparation  of   in  situ   surface-modified  copper  doped  zno nanoparticles (cu:zno nps) was done according to standard procedure.assay for antimicrobial activity of cu:zno nps against bacterial pathogens was carried out...
