In this work, we demonstrate the use of a single DNA strand and G-quadruplex-specific dye NMM as a label-free switch for the construction of series of basic logic gates (YES, NOT, OR, INHIBIT, NOR, AND). The simple GT-rich sequence could be used to interact with several molecules (K(+), thrombin, Hg(2+), and Pb(2+)) to form different structures that can be distinguished by the label-free dye NM...

We study the definable topological dynamics (G(M),SG(M)) of a group acting on its type space, where M is either an o-minimal structure or p-adically closed field, and G definably amenable group. focus problem raised in [13] whether weakly generic types coincide with almost periodic types, showing that answer positive when has boundedly many global types. also give two “minimal counterexamples” ...

Rotavirus is a major etiologic agent of gastroenteritis in infants and young children worldwide, and also in variety of mammals and birds. The most prevalent species of rotavirus, i.e., group A rotavirus is highly diverse antigenically and genetically. Two major outer capsid proteins of rotavirus, VP7 and VP4, contain neutralization antigens. Based on the antigenicities and gene sequence divers...

Dot and Northern blot hybridization assays were used to analyze field strains of group A bovine rotaviruses (BRVs) by using nucleic acid probes representing P and G type specificities. The probes were prepared by polymerase chain reaction amplification of hyperdivergent regions of the cloned VP4 (nucleotides 211 to 686) and VP7 (nucleotides 51 to 392) genes from four serotypically distinct (in ...

Aim: the present study aimed to design and validate decentering schemes for decision making about curriculum based on Schwab’s practical theory and features of the educational system in Iran. Method: in the first step, qualitative methods of "Speculative Essay", "Evaluative Inquiry: Situational Assessment", and "Integrative Inquiry: The Research Synthesis" were employed to explain decentering ...
