Protein synthesis inhibitors and catalytic RNA Effect of puromycin on tRNA precursor processing by the RNA component of Escherichia coli RNase P

AbstractRNase P and ribosomes must interact with similar substrate molecules, tRNA precursors in the case of RNase P and aminoacyl-, peptidyl- or free tRNAs in the case of ribosomes. In order to compare the substrate recognition mechanisms between ribosomes and RNase P, protein synthesis inhibitors have been assayed for their effect on the catalytic activity of the RNA component of Escherichia coli RNase P (M1 RNA). Puromycin has an inhibitory effect that could be related to similar substrate recognition mechanisms by rRNA in the ribosome and by M1 RNA in RNase P

On Montel's theorem and Yang's problem

AbstractLet F be a family of meromorphic functions defined in a domain D, and let ψ (≢0) be a function meromorphic in D. For every function f∈F, if (1) f has only multiple zeros; (2) the poles of f have multiplicity at least 3; (3) at the common poles of f and ψ, the multiplicity of f does not equal the multiplicity of ψ; (4) f(z)≠ψ(z), then F is normal in D. This gives a partial answer to a problem of L. Yang, and generalizes Montel's theorem. Some examples are given to show the sharpness of our result

Norovirus infection in immunocompromised hosts

AbstractAcute gastroenteritis caused by noroviruses often has a duration of 2–0 days and is characteristically self-limiting. In contrast, chronic infection caused by noroviruses in immunocompromised individuals can last from weeks to years, making clinical management difficult. The mechanisms by which noroviruses establish persistent infection, and the role of immunocompromised hosts as a reservoir for noroviruses in the general human population, are not known. However, study of this patient cohort may lead to new insights into norovirus biology and approaches to treatment
