Introduction Successful completion of chromosome segregation and cytokinesis requires the coordinated activation and inactivation of numerous mitotic regulators. Inactivation is largely brought about by ubiquitindependent proteolysis, with the relevant E3 ubiquitin ligase being the anaphase promoting complex, or cyclosome (APC/C) (Irniger et al., 1995; King et al., 1995; Sudakin et al., 1995). ...

This work aims to evaluate its effect on cell density, biomass, and proximal composition in semicontinuous cultures. Thalassiosira weissflogii was cultivated five culture media, for which the f medium taken as reference, concentrations of nitrates, phosphates, silicates were modified up a factor four treatments (f/4, f/2, f, 2f, 4f). Cell density biomass increased initial nutrients rose treatme...

BackgroundRespiratory syncytial virus (RSV) is a major cause of lower respiratory infection among children and no vaccine available. The stabilized form the fusion (F) protein – pre-F leading candidate to target different populations, including pregnant women. This study aimed determine magnitude nature RSV-directed maternal antibodies (matAbs) in hospitalized with RSV infection.MethodsSixty-fi...

some factors affecting crude protein balance (cpb), as a measure of efficiency, were studied using 2824 records of 501 lactating holstein cows. the cpb (kg d-1) was calculated as crude protein (cp) intake (kg) minus cp yield (kg). two different statistical methods including principal components (pcs) and general linear model analyses were used to study the effects of different factors. crude pr...

Newcastle disease (ND), caused by the virus (NDV), is transmitted poultry with severe infectivity and a high fatality rate. The fusion (F) protein on NDV envelope facilitates merger of viral host cell membranes help homologous hemagglutinin-neuraminidase (HN). transmembrane (TM) domains proteins are typically required for fusion, but key amino acids in F TM have not been identified. Site-direct...

Hepatitis C virus (HCV) F protein is encoded by the +1 reading frame of the viral genome. It overlaps with the core protein coding sequence, and multiple mechanisms for its expression have been proposed. The full-length F protein that is synthesized by translational ribosomal frameshift at codons 9 to 11 of the core protein sequence is a labile protein. By using a combination of genetic, bioche...
