Paper chromatography has proved to be a powerful tool in an antibiotic screening program (1). It serves the following purposes: (a) it pro vides an early characterization of the antibiotic activity as new or old, (6) it determines whether single or multiple activities are present, and (c) it predicts the solubility characteristics of the activ ity and probable extraction behavior. Thus, at a ve...

The objective of this study was to determine the chemical compounds of Iranian propolis (IP) extracts and to show flavonoids and phenol effects on methane production, fermentation characteristics and rumen microbial population (in vitro). In this study two diets with different concentrate: forage ratios as (HC: high concentrate) and (MC: middle concentrate), respectively as non-supplemented or ...

Root iron mobilization genes are induced by iron deficiency downstream of an unknown signaling mechanism. The FER gene, encoding a basic helix-loop-helix domain protein and putative transcription factor, is required for induction of iron mobilization genes in roots of tomato (Lycopersicon esculentum). To study upstream regulatory events of FER action, we examined the control of FER gene and FER...

Introduction: The term malolactic fermentation (MLF) indicates a range of metabolic reactions by strains of lactic acid bacteria, usually Oenococcus oeni. MLF influences the organoleptic traits of wine and is necessary for the aging of red wines and certain white wines (LONVAUD-FUNEL 1999). However, the activities of malolactic bacteria (MB) in wine are affected by numerous factors, among which...

UNLABELLED Epidermal growth factor receptor (EGFR) is frequently amplified or mutated in non-small cell lung cancer (NSCLC). Although Fer protein-tyrosine kinase signals downstream of EGFR, its role in NSCLC tumor progression has not been reported. Here, Fer kinase was elevated in NSCLC tumors compared to normal lung epithelium. EGFR signaling in NSCLC cells fosters rapid Fer activation and inc...

FER tyrosine kinase (FER) has been demonstrated to play a critical role in tumorigenesis and metastasis; however, its potential value as a novel prognostic marker for clear cell renal cell carcinoma (ccRCC) remains unclear. In 48 paired samples of ccRCCs and normal adjacent tissues (ADTs), real-time PCR was used to evaluate the expression of FER mRNA. The expression of FER protein was assessed ...
