This study was conducted to determine the concentration of five heavy metals, including lead, cadmium, mercury, arsenic, and chromium in muscle, liver and gills of the gray mullet, Liza aurata in southern part of the Caspian Sea. The samples were collected during sexual maturity (in the fall) and sexual rest (in the spring). The mean concentration of lead, cadmium, mercury, arsenic, and chromiu...

Assessment of the ecological quality of theMinho estuary (Northwest Iberian Peninsula) based on metal concentrations in sediments and in Corbicula fluminea The concentrations of metals (Cd, Cr, Cu, Fe, Ni, Pb and Zn) in sediments and the soft tissues of Corbicula fluminea from the Minho estuary (Northwest Iberian Peninsula) were determined to assess the spatial variation of metal bioavailabilit...

The purpose of this work is to compare computed radiography (Kodak CR 400) and film/screen combination (Speed 400) systems in regards of patient dose, technique settings, and contrast-detail detectability. A special contrast-detail phantom with drilled holes of varying diameter (detail) and varying depth (contrast) was utilized. Various thicknesses of the Lucite sheets were utilized to simulate...

  The Akhal-Teke is an ancient horse originat-ing from Asia where it was used by nomadic tribes and used as a warhorse. Lameness examinations require proper interpretation of clinical and radiographic findings. Therefore, understanding of normal radiographic findings of the foot is necessary. Although the radiographic appearance of the normal foot must be understood to recognize abnormalities ...

Background: Persian Gulf is a semi-closed environment which is affected by pollution ‎from heavy metals. Entrance of heavy metals to the water column and binding to ‎sediment particles can affect the benthic organisms that can accumulate these ‎materials in their body. Noticing this ability, mussels are considered as bio-monitoring ‎agents.‎ Methods: The pearl oyster, Pinctada radiate, and sed...

BACKGROUND Human dirofilariasis is a zoonotic infection that continues to spread to previously unaffected areas of Europe. In the South Moravian Region of the Czech Republic (CR), imported as well as autochthonous canine infections were recorded in the last decade, and parasite DNA was detected in mosquitoes of Aedes vexans. In the present paper, human Dirofilaria infections are reported from t...

Using two biological characteristics of the land snail (subspecies Helix aspersa aspersa and Helix aspersa maxima), i.e., soil eating and crawling on wet surfaces, methods were developed to assess the bioavailability of heavy metals (Cd, Cr, Pb, and Zn) from soil and aqueous leachates of soil. Measurement of heavy-metal concentrations in soil, leachates, and soft tissues of snails showed that c...
