Abstract:
... The rRNA genes [ribosomal DNA (rDNA)] are organized in a prominent nuclear compartment, the nucleolus. It is now well established that the nucleolus functions beyond ribosome biosynthesis, regulating several physiological cellular responses. The nucleoli constitute dynamic genomic/nuclear hubs and demonstrate unique inherent characteristics, rendering them ideal to sense, signal, and respond to va ...

The contents of f-SatIII and TR in schizophrenic (SZ) patients were found to be lower than in healthy controls (HC) in previous studies. The major question of this study was: ‘What are the f-SatIII and TR C ...

Abstract:
... Argophyllaceae is a small eudicot family of trees and shrubs of south-western Pacific distribution, comprising two genera: Corokia and Argophyllum. The phylogeny of Corokia, which contains six species, has attracted little attention so far, the genus being usually represented by a single species in studies looking at relationships at higher taxonomic levels. Here we bridge this knowledge gap with ...

These nematodes, with phyto-sanitary potential, are frequently ignored or misdiagnosed as pests, and this may pose a threat to food security. The accuracy of its identification based on a morphological approach has been challenged recently, due to the overlappi ...
