Author:Magagula, L; Gagliardi, M; Naidoo, Jerolen; Mhlanga, MusaDate:Aug 2017Termed 'master gene regulators' long ncRNAs (lncRNAs) have emerged as the true vanguard of the 'noncoding revolution'. Functioning at a molecular level, in most if not all cellular processes, lncRNAs exert their effects systemically. Thus, ...Read more
Author:Shibayama, Y; Fanucchi, Stephanie; Magagula, L; Mhlanga, MusaDate:May 2014Recent functional studies have unveiled the significant role chromatin topology plays in gene regulation. Several lines of evidence suggest genes access necessary factors for transcription by forming chromatin loops. A clearer picture of the ...Read more
Author:Asaka, OT; Adejo, A; Onumanyi, Adeiza J; Bello-Salau, H; Oluwamotemi, FTDate:Jul 2021Cellular users are often considered to be uniformly distributed within the communication network for the purposes of simplified analysis. Based on this assumption, the inter-cell interference experienced by users has been handled using soft ...Read more
Author:O'Farrell, Patrick J; Donaldson, JS; Hoffman, MTDate:Aug 2009Renosterveld is a grassy shrubland with a diverse understory of geophytes. Exceptional plant diversity and endemism, combined with considerable fragmentation due to transformation to cropland, make this vegetation type a conservation priority. ...Read more
