BACKGROUND To quantitatively compare in-vitro and in vivo membrane transport studies of targeted delivery, one needs characterization of the magnetically-induced mobility of superparamagnetic iron oxide nanoparticles (SPION). Flux densities, gradients, and nanoparticle properties were measured in order to quantify the magnetic force on the SPION in both an artificial cochlear round window membr...

One of the ways to increase energy efficiency and intensity blast furnace smelting, especially when using pulverized coal fuel, is hot strength coke. In conditions OJSC NLMK, an oil additive was introduced into charge improve coke quality. At same time, sulfur content in increases, and, consequently, cast iron increases as well. this regard, task finding desulfurization becomes urgent. The main...

Background Because of the limited endogenous repair mechanisms that exist in the heart, exogenous stem cell therapies offer the potential to provide the building blocks for repair and/or evoke developmental pathways to recruit endogenous cells that can prevent adverse remodeling and promote healing. MR-labeling of stem cells with iron oxides has been used to track stem cells in the heart, but c...

there is documented evidence that infection in laboratory animals can often influence the outcome of experiments. all infections, apparent or inapparent, are likely to increase biological variability. as a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 ) and 105 guinea pigs (f...

The ligands that bind iron and heme in reticulocyte and may regulate their distribution are not known. Guinea pig reticulocyte hemolysates were labeled with 59Fe and filtered through molecular weight sieving columns. 59Fe-containing peaks of ferritin, transferrin, and hemoglobin were identified, as well as a low molecular weight peak containing predominantly nonheme iron, and a 17,000 mol wt he...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

47 NC and AC1 treatments (P<0.05). N digestibility was higher in both PC and AC3 treatments compared with NC and AC1 treatments (P<0.05). The RBC count was increased in ALA treatment compared with NC treatments (P<0.05). Hemoglobin in AC2 treatment was higher than NC treatment (P<0.05). Lymphocyte, WBC, IgG and total iron binding capacity were not affected among all treatments (P<0.05). The red...

WILLIAMS, ID. M., G. K. LEE, AND G. E CARTWRIGIIT. Fb-roxidasc nctivity of rat ccruloplasmin. Am. J. Physiol. 227(5) : 1094-1097. 1974.-The ferroxidase activity of rat ceruloplasmin was studied under various assay conditions. The ferroxidase activity was optimal at pH 6.0-6.2 in acetate buffer in the absence of ascorbate, and under these conditions the activity was about 1/3rd that of human cer...

The material comes from the Late Iron Age settlement of Dobrovăț-La Livadă in Iași County and represents food waste presenting butchering, burning, disarticulation marks. Considering total number specifically identified mammals, 90.36% them belong to domestic mammals rest 9.64% belongs only wild – Sus scrofa Cervus elaphus. Estimating slaughter ages provided little data, both due high degree bo...
