Cost-effectiveness analysis of Canada’s National Overdose Response Service [PDF]
BMJ OpenObjectives We evaluate the cost-effectiveness of Canada’s National Overdose Response Service (NORS) and in particular, highlight the conditions under which the cost-effectiveness decision would change, given the uncertainty in estimating the overall risk

Novel Nitric Oxide-Releasing Formulations Show Fungicidal Potential for Superficial Dermatophyte Infection [PDF]
Journal of FungiA commercially available nitric oxide (NO)-releasing solution (NORS) has demonstrated in vitro efficacy for dermatophytosis, but a NO-releasing gel (NORG) may be more suitable for patient self-application.

Positioning of NORs and NOR-bearing chromosomes in relation to nucleoli
Journal of Structural Biology, 2007 It is widely accepted that chromosomes occupy more or less fixed positions in mammalian interphase nucleus. However, relation between large-scale order of chromosome positioning and gene activity remains unclear. We used the model of the human ribosomal genes to address specific aspects of this problem.

Nucleolar number variation in Fritillaria (Liliaceae) taxa from Greece [PDF]
Botanica Serbica, 2023 The current study aims to estimate the most frequent number of nucleoli in taxonomically interesting Fritillaria species. Silver nitrate staining is applied using a modified protocol in 14 taxa and one hybrid from 17 populations from Greece.

Interplay of ribosomal DNA loci in nucleolar dominance: dominant NORs are up-regulated by chromatin dynamics in the wheat-rye system. [PDF]
PLoS ONE, 2008 BACKGROUND: Chromatin organizational and topological plasticity, and its functions in gene expression regulation, have been strongly revealed by the analysis of nucleolar dominance in hybrids and polyploids where one parental set of ribosomal RNA (rDNA ...
