sour cherry and orange juice were successfully cryoconcentrated. novel clarification (electro-flotation and ultra-filtration) improved cryconcentration efficiency. ef-uf clarified sour cherry and orange juices were cryoconcentrated in three stages up to 34.52±0.14, 44.42±0.19, 52.44±0.13 and 28.43±0.16, 40.51±0.15, and 45.42±0.19° brix at -10˚c respectively. duncan's multiple range test was use...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
BACKGROUND Because hemodiafiltration (HDF) involves large amounts of ultra-filtration and substitution fluid infusion, its effects on serum electrolytes may be different from those of hemodialysis (HD). Serum sodium and blood pressures were compared between patients undergoing online HDF and high-flux HD (HFHD). METHODS Thirty-two of 101 patients on HFHD switched voluntarily to online HDF. Th...
To determine the renal effects of inhibiting the uptake and subsequent metabolism of endogenous adenosine, dipyridamole, a nucleoside transport inhibitor, was infused intrarenally into anesthetized dogs. Dipyridamole (24 micrograms/kg per min) inhibited the cellular extraction of [14C]adenosine (72 +/- 3% vs. 9 +/- 3%) and elevated the excretion of endogenous adenosine (0.60 +/- 0.08 to 1.70 +/...

Date juice was treated by cross- flow ultra-filtration with molecular weight cut-off (MWCO) of 5 kDa. Optimized levels of feed brix, TMP and operation time were determined as 47.13, 82.11 psi and 30 min, respectively. Under such conditions, 80.94% decolourisation and 97.78 % turbidity reduction were obtained while loss of glucose and fructose were estimated to be only 3.49% and 9.62%, respectiv...

BACKGROUND AND OBJECTIVES This study aimed at evaluating acute radiological contrast effects in fluid restriction situations, observing renal and cardiovascular effects after intra-arterial injection of high osmolarity radiological contrast. METHODS Participated in this study 16 dogs anesthetized with sodium thiopental (15 mg.kg-1) and fentanyl (0.03 mL.kg-1), followed by continuous infusion ...
