European field evaluation of monensin, a new anticoccidial agent

Arohynapene D, a new anticoccidial agent produced by Penicillium sp. FO-2295.

from the strain led to the discovery of another active compound named arohynapene D (Fig. 1). In this paper, the isolation, physico-chemical properties, structure determination and biological characteristics of arohynapene D are described. The seed and production media for arohynapene D production were the same as reported previously1}. To obtain enough amount of arohynapene D, a jar fermentati...

The efficacy of a poultry commercial anticoccidial vaccine in experimental challenge with Eimeria field isolates

BACKGROUND: The control of coccidiosis in poultry industryis dominated by prophylactic chemotherapy; however,drug resistance is a serious problem. Alternative control methodssuch as vaccination have been accepted as a practical method forcontrolling coccidiosis in chickens. Considering the immunologicalvariation of Eimeria strains, the efficacy of live coccidiosisvaccines may be compromised. OB...

Evaluation of a new bombesin analogue labeled with 99mTc as potential targeted tumor scintigraphic agent

Background: Bombesin shows high affinity for Gastrin-releasing peptide (GRP) receptors which over expressed on the cell surfaces of several human tumors particularly in prostate and breast cancers. The aim of this study was labeling of designed analogue with99mTc via HYNIC and Tricine /EDDA and evaluation as potential targeted tumor scintigraphic agent. Materials and Methods: HYNIC-Bombesin wa...

fabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions

a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
