Linguistic combinations are referred to as a chain of words that associate with one another and form a semantic phrases, such as adjectival and noun. Innovation in this field is one of the main tasks of creative poetry. Shams's sonnets are of the prominent works of Persian literature and their composition is characterized by its stylistic features. In order to express his sublime and mystical t...

It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...

Multi-sensory information is a generic concept since such information is of concern in all robotic systems where information processing is central. In such systems for the enhancement of the accurate action information redundant sensors are necessary where not only the number of the sensors but also the resolutional information of the sensors can vary due to information with different sampling ...

UNLABELLED HIV-1 Env glycoprotein-mediated fusion is initiated upon sequential binding of Env to CD4 and the coreceptor CXCR4 or CCR5. Whereas these interactions are thought to be necessary and sufficient to promote HIV-1 fusion, other host factors can modulate this process. Previous studies reported potent inhibition of HIV-1 fusion by selective P2X1 receptor antagonists, including NF279, and ...

Formation of a fusion pore between a vesicle and its target membrane is thought to involve the so-called SNARE protein complex. However, there is no mechanistic model explaining how the fusion pore is opened by conformational changes in the SNARE complex. It has been suggested that C-terminal zipping triggers fusion pore opening. A SNAP-25 mutant named SNAP-25Delta9 (lacking the last nine C-ter...

background: parathyroid hormone (pth) secreted by parathyroid glands regulates the metabolism of calcium and phosphorus in bone and kidney. thereby, it can stimulate bone formation, and is a promising agent in the treatment of osteoporosis. mature form of pth consists of 84 amino acids; however, the first 34 residues of pth cover the majority of hormonal action. methods: in this study, the fusi...
