E. Anomohanran, U. B. Owhe-Ureghe, D. A. EhwariemeThe failure of antimicrobial agents in the treatment of some ailments has become a great concern to health care practitioners. This could be as a result of low quality drugs, sneaked into the market by those who fake them, thus, this study was carried out to evaluate the sensitivity of various brands of Amoxicillin and Ampicillin on clinical isolates of … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 22 Oct 2014 · 8,206 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Effect of Heat or Heat-Xylose Processing on Nitrogen Fractions and in Situ/In Vitro Ruminal and Post-Ruminal Protein Disappearance of Guar MealHossein Jahani-Azizabadi, Mohsen Danesh Mesgaran, Ali Reza Vakili et al.Problem statement: Guar meal is a by-product consisting of hull and germ and is mostly used as a protein source in poultry and ruminant rations. The aim was to determine the effect of heat or heat-xylose processing on nitrogen fractions, in situ ruminal degradation parameters and in situ/in vitro ruminal and post-ruminal disappearance of guar meal. Approach: Samples were intact … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 8,153 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,025 accessesView PDF Cite
