this experiment was conducted to evaluate the effect of different levels of crude protein and threonine on performance, carcass characteristics and immune system of broiler chickens during starter (7-24) and grower (25-42) periods. a total of 288 male broiler chicks of ross 308 strain were used in a completely randomized design with factorial arrangement (2×4) with three replicates in each trea...

Proteomics enables understanding the composition, structure, function and interactions of the entire protein complement of a cell, a tissue, or an organism under exactly defined conditions. Some factors such as stress or drug effects will change the protein pattern and cause the present or absence of a protein or gradual variation in abundances. Changes in the proteome provide a snapshot of the...

background: it seems that the success of vaccination for cancer immunotherapy such as dendritic cell (dc) based cancer vaccine is hindered through a powerful network of immune system suppressive elements in which regulatory t cell is the common factor. foxp3 transcription factor is the most specific marker of regulatory t cells. in different studies, targeting an immune response against regulat...

synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants the concept of synchronization energy and protein was first by jhonson, implying that maximum microbial protein synthesis could be achieved by matching the rate of organic matter and protein degradation. synchronization of rumen available...

Protein-protein interactions are essential in diverse cellular processes including signal transduction. It is not uncommon for protein-protein the transmembrane signaling to exhibit low binding affinities with a dissociation constant μM range or higher. Presumably, membrane proteins can selectively bind their partners via low-affinity because they only diffuse laterally plane and interact withi...
