vacuolar h+-translocation pyrophosphatase (v-ppase) and na+/h+ antiporter (v-na+/h+) are important transporters in plant cells and have essential roles against abiotic stresses. in this study, the effects of salt stress were surveyed on the transcription of v-ppase pump and na+/h+ antiporter genes at early times of nacl treatment in roots of halophytic grass leptochloa fusca through the real ti...

In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

objective: alpha-thalassemia is one of the most prevalent hemoglobin disorders in the world and it is a common hereditary condition caused by deletion of one or more α-globin genes. common α-thalassemia deletions like 3.7 kb, 4.2 kb, 20.5 kb and med can be detected by multiplex pcr. there are, however, some unknown deletions that can not be detected by the mentioned method or even by direct dna...

viruses are the most common causes of aseptic meningitis. early detection, treatment and management of viral meningitis are priority. this study aimed to evaluate common viral meningitis in children referred to taleghani pediatrics hospital in gorgan, south east of caspian sea, iran. in this descriptive study csf and blood samples were taken from 40 children with negative bacterial culture who ...

background contamination of therapeutic recombinant proteins with residual host cell dna must be controlled under the regulatory standards. objectives the current study established a new rapid, sensitive real time polymerase chain reaction (pcr) approach to measure the reliably of the residual escherichia coli (e. coli) host cell genomic dna in the recombinant streptokinase and alfa interferon ...
