The metabolism of transferrin-bound indium and iron were compared by in vivo studies in the rat. Rats were injected with serum transferrin labeled with “In and “Fe, and, at intervals ranging from 20 mm to 5 days after injection, they were killed. They were perfused through the portal vein with 200 ml of 0.9% saline, and the residual radioactivity, expressed as a percentage of the injected dose,...

STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...

Magnetite (Fe₃O₄) is a ferromagnetic iron oxide of both Fe(II) and Fe(III), prepared by FeCl₂ and FeCl₃. XRD was used for the confirmation of Fe₃O₄. Via the modification of Tetraethyl orthosilicate (TEOS), (3-Aminopropyl)trimethoxysilane (APTMS), and Alginate (AA), Fe₃O₄@SiO₂, Fe₃O₄@SiO₂-NH₂, and Fe₃O₄@SiO₂-NH₂-AA nanoparticles could be obtained, and IR and SEM were used for the characterizatio...

Fe Mössbauer spectroscopy was used to study the uptake and distribution of iron in the root of cucumber plants grown in iron-deficient modified Hoagland nutrient solution and put into iron-containing solution with 10 μM Fe citrate enriched with Fe (90%) only before harvesting. The Mössbauer spectra of the frozen roots exhibited two Fe components with typical average Mössbauer parameters of δ=0....

this work investigates the use of fenton’s process (ph 5.5 and 6; 0.10-0.50 mm fe(ii); molarratios fe(ii) to h2o2 of 1:5-1:20) combined with flocculation for the treatment of groundwater which is richin natural organic matter (nom) (10.6±0.37 mg c/l) and arsenic (110±6.7 μg/l). changes to the character ofthe residual nom fractions were followed, as well as the removal efficiencies of nom and ar...

Purpose The effect of sagittal plane angle of the tibial tunnel on the severity of tibial intra-articular aperture expansion caused by iatrogenic re-reaming in anterior cruciate ligament (ACL) reconstruction using a modified transtibial technique is unknown. The purpose of this study was to compare the severity of intra-articular aperture widening at different angles (40°, 45°, and 50°) of the ...

Summary The quality and provenance of seed are exceptional importance for the production yield cultivated plants. There numerous tests determination vigour. accelerated ageing test is one most important that provide degree germination preservation longevity in storages. aim this study was to observe effect different methods – organic conventional on vigour maize (variety Rumenka), using test. M...

Cytosine Deaminase (CD) from Aspergillus parasiticus was purified and characterized. Time course for maximal CD production (50 μmol/min/mg) was at 72 hrs. The enzyme was purified 387.73 folds with an overall yield of 13%. The CD had pH optimum of 7.2, a temperature optimum of 40 ̊C 45 ̊C, activation energy (Ea) of 8.4 KJ/mol and a t1/2 of 1.10 hr. A. parasiticus CD stoichiometrically deaminated C...
