Protease activities were detected in quiescent and germinating spores of the ostrich fern (Matteuccia struthiopteris [L.] Todaro). Peak endopeptidase, aminopeptidase, and carboxypeptidase activities were detected 12 to 24 hours after spores began imbibing under light. There was a correlation between activities of proteases, the onset of a decline in levels of soluble protein, and an increase in...

In this work, we explore the potential of the metalloendopeptidase Lys-N for MALDI-MS/MS proteomics applications. Initially we digested a HEK293 cellular lysate with Lys-N and, for comparison, in parallel with the protease Lys-C. The resulting peptides were separated by strong cation exchange to enrich and isolate peptides containing a single N-terminal lysine. MALDI-MS/MS analysis of these pep...

In Pakistan, ostrich farming is becoming more popular as a means of obtaining inexpensive meat that also devoid cholesterol and other diseases when compared to chicken. the wild, ostriches dwell in flocks five fifty perform well captivity. Ostrich chicks' early development rate critical preparing bird for later growth up till slaughter mass. The original egg mass from which emerges determines h...

BACKGROUND: Newcastle disease virus (NDV) is the causativeagent of the Newcastle disease (ND), a highly contagiousdisease in birds that causes significant economic losses to thepoultry industry worldwide. ND is endemic in Iran and outbreaksare reported regularly in commercial poultry flocks and differentspecies of birds. OBJECTIVES:The current study was carried outto characterize NDV based on p...

there are significant structural differences between the mouth and pharyngeal cavity of birds and mammals. it is usual to refer to a common oropharyngeal cavity of birds because the soft palate, which forms such an obvious delineation between the mouth and pharyngeal cavity, is absent. six male adult ostriches were used to study the oropharyngeal cavity and its components including the beak, ha...

samples of formalin fixed gastrointestinal organs of three month ostrich chicks were submitted to the department of pathology, razi vaccine and serum research institute. histologically hepatitis and pancreatitis with large eosinophilic intra nuclear inclusion bodies were prominent in hepatic and pancreatic cells. these inclusions were suspected as adenovirus inclusion body hepatitis (ibh) in va...
