landscape ecology as a modern interdisciplinary science offers new concepts, theories, and methods for land evaluation and management. a main part of landscape ecology is describing patterns in the landscape and interpreting the ecological effects of these patterns on flora, fauna, flow of energy and materials. remote sensing and gis techniques have a high ability for landscape researchers to s...

Aflatoxins are a group of secondary fungal metabolites that occur widely in natural contaminants of many feeds under high humidity and temperature, and are potentially dangerous to fish. Therefore, this study was designed to investigate the effects of aflatoxins on some plasma biochemical indices, as clinical biomarkers, in common carp, Cyprinus carpio. Fish were fed diets contaminated with 0 (...

the relationship between different indices of the copper deficiency was studied in 136 slaughtered male cattle (< 2 years). copper status has been detected as marginally deficient in 57.4, 36.4, 34.6, and 28.2% of cattle based on the copper concentrations in plasma (5.5-14.5 μmol/l) and liver (19.7-189.1 mg/kgdm), plasma ceruloplasmin levels (85.4 - 178.2 mg/l) and erythrocyte superoxide dismut...

Sentinel missions provide widespread opportunities of exploiting inter-sensor synergies to improve the operational monitoring terrestrial photosynthetic activity and canopy structural variations using vegetation indices (VI). In this context, continuous consistent temporal data are logically required rapidly detect changes across sensors. Nonetheless, existing limitations inherent satellite orb...

INTRODUCTION Numerous studies performed in recent years have shown protective effects of N-acetylcysteine (NAC) on cardiac and renal tissue damage following ischemia/reperfusion injury. We assessed the effectiveness of systemic administration of NAC, at a therapeutic dose, in a rat model of a 1-hour 720-degree testicular torsion/detorsion. MATERIALS AND METHODS Sprague-Dawley rats were divide...
