While scholars have explored how business has increasingly been involved in socio-political issues (Scherer et al., 2016; van der Meer & Jonkman, 2021), less attention has been given to the process of how businesses are held accountable for those issues by stakeholders (Reinecke & Ansari, 2016). Current studies show that multinational corporations are sometimes forced to take a stand on di

Industrial symbiosis, a concept derived from industrial ecology, emphasizes the collaborative and synergic production among industries. The particular focus is on cyclical flows of resources (material, energy, water, and/or by-products), in order to minimize impacts on the environment. In this way, an industry could reuse the discarded resources of another industry as an input to production. Essen

Nonsense-mediated mRNA decay (NMD) is a surveillance mechanism that detects and degrades transcripts containing premature translation termination codons. Gene expression profiling experiments have shown that inactivation of the NMD pathway leads to the accumulation of both aberrant, nonsense-containing mRNAs, and many apparently wild-type transcripts. Such increases in transcript steady-state leve

Elongator has been reported to be a histone acetyltransferase complex involved in elongation of RNA polymerase II transcription. In Saccharomyces cerevisiae, mutations in any of the six Elongator protein subunit (ELP1-ELP6) genes or the three killer toxin insensitivity (KTI11-KTI13) genes cause similar pleiotropic phenotypes. By analyzing modified nucleosides in individual tRNA species, we show th

ObjectiveTo study the cumulative live birth rate (CLBR) after the first in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment in women with or without deep-infiltrating endometriosis (DIE) and/or endometrioma diagnosed by transvaginal ultrasonography (TVUS), using the International Deep Endometriosis Analysis (IDEA) group definitions.DesignProspective observational coho

The Saccharomyces cerevisiae Elongator complex consisting of the six Elp1-Elp6 proteins has been proposed to participate in three distinct cellular processes: transcriptional elongation, polarized exocytosis, and formation of modified wobble uridines in tRNA. Therefore it was important to clarify whether Elongator has three distinct functions or whether it regulates one key process that leads to m

A 5-methyluridine (m(5)U) residue at position 54 is a conserved feature of bacterial and eukaryotic tRNAs. The methylation of U54 is catalyzed by the tRNA(m5U54)methyltransferase, which in Saccharomyces cerevisiae is encoded by the nonessential TRM2 gene. In this study, we identified four different strains with mutant forms of tRNA(Ser)CGA. The absence of the TRM2 gene in these strains decreased t

Nonsense-mediated mRNA decay (NMD) is a conserved eukaryotic quality control mechanism which triggers decay of mRNAs harboring premature translation termination codons. In this chapter, I describe methods for monitoring the influence of NMD on mRNA abundance and decay rates in Saccharomyces cerevisiae. The descriptions include detailed methods for growing yeast cells, total RNA isolation, and Nort

The translational decoding properties of tRNAs are modulated by naturally occurring modifications of their nucleosides. Uridines located at the wobble position (nucleoside 34 [U(34)]) in eukaryotic cytoplasmic tRNAs often harbor a 5-methoxycarbonylmethyl (mcm(5)) or a 5-carbamoylmethyl (ncm(5)) side chain and sometimes an additional 2-thio (s(2)) or 2'-O-methyl group. Although a variety of models

The yeast Saccharomyces cerevisiae provides an ideal model system for elucidation of the molecular mechanisms that regulate the nonsense-mediated mRNA decay (NMD) pathway. This chapter describes an array of molecular biological, genetic, and biochemical tools that facilitate the characterization of transcripts that comprise NMD substrates and provide insights into the roles of the upf/nmd proteins

Inactivation of the yeast nonsense-mediated mRNA decay (NMD) pathway stabilizes nonsense mRNAs and promotes readthrough of premature translation termination codons. Although the latter phenotype is thought to reflect a direct role of NMD factors in translation termination, its mechanism is unknown. Here we show that the reduced termination efficiency of NMD-deficient cells is attributable to incre

The conserved pre-mRNA retention and splicing (RES) complex, which in yeast consists of Bud13p, Snu17p and Pml1p, is thought to promote nuclear retention of unspliced pre-mRNAs and enhance splicing of a subset of transcripts. Here, we find that the absence of Bud13p or Snu17p causes greatly reduced levels of the modified nucleoside N(4)-acetylcytidine (ac(4)C) in tRNA and that a lack of Pml1p redu

Kluyveromyces lactis killer strains secrete a heterotrimeric toxin (zymocin), which causes an irreversible growth arrest of sensitive yeast cells. Despite many efforts, the target(s) of the cytotoxic gamma-subunit of zymocin has remained elusive. Here we show that three tRNA species tRNA(Glu)(mcm(5)s(2)UUC), tRNA(Lys)(mcm(5)s(2)UUU), and tRNA(Gln)(mcm(5)s(2)UUG) are the targets of gamma-toxin. The

The presence of 5-methyluridine (m5U) at position 54 is a ubiquitous feature of most bacterial and eukaryotic elongator tRNAs. In this study, we have identified and characterized the TRM2 gene that encodes the tRNA(m5U54)methyltransferase, responsible for the formation of this modified nucleoside in Saccharomyces cerevisiae. Transfer RNA isolated from TRM2-disrupted yeast strains does not contain

The biogenesis of transfer RNA is a process that requires many different factors. In this study, we describe a genetic screen aimed to identify gene products participating in this process. By screening for mutations lethal in combination with a sup61-T47:2C allele, coding for a mutant form of, the nonessential TAN1 gene was identified. We show that the TAN1 gene product is required for formation o

Bakgrund: Att ha ett spädbarn som vårdas på en neonatalavdelning är påfrestande och ångestfyllt för föräldrar. Känguruvård är en vårdmetod där spädbarnet ligger hud mot hud med sin förälder, vilket medför hälsofördelar för både spädbarnet och föräldern. Syfte: Syftet med den systematiska litteraturöversikten var att undersöka föräldrars upplevelser av att vårda sitt prematurfödda spädbarn i kängur

Bakgrund - Barn som genomgår dagkirurgiska ingrepp upplever svår smärta i hemmet efteråt. För att minska risken för kronisk postoperativ smärta krävs en adekvat smärtlindring av den akuta postoperativa smärtan. Föräldrar har visat sig göra en bristfällig skattning av sina barns postoperativa smärta i hemmet. Syfte - Att undersöka barns, i åldern 8 till 17 år, postoperativa självskattade smärta i h
