Results suggest that emotion malleability beliefs predict avoidance and related psychological outcomes across the academic year.We investigated the effect of second language use on the experienced vividness and emotionality of negative autobiographical memories. Fifty native Swedish speakers with English as their second language were asked to recall a negative episodic memory from their past in their native language. Half the participants were then asked to reactivate the same memory in their first language while the other half were asked to reactivate it in their second language, and then rate their experienced vividness and emotionality a second time. Following this reactivation, experienced emotionality was reduced for both groups of participants, with a similar magnitude of reduction for both groups. Experienced vividness, however, was only reduced for the group who reactivated the memory in their second language. No difference in intrusion frequency was found between the groups at a one-week follow-up. The results provide increased insight into how a second language can affect the experienced emotionality and vividness of a negative autobiographical memory.WDR45 and WDR45B are β-propeller proteins belonging to the WIPI (WD repeat domain, phosphoinositide interacting) family. Mutations in WDR45 and WDR45B are genetically linked with beta-propeller protein-associated neurodegeneration (BPAN) and intellectual disability (ID), respectively. WDR45 and WDR45B are homologs of yeast Atg18. Atg18 forms a complex with Atg2 for autophagosome biogenesis, probably by transferring lipids from the ER to phagophores. We revealed that WDR45 and WDR45B are critical for autophagosome-lysosome fusion in neural cells. WDR45 and WDR45B, but not their disease-related mutants, bind to the tether protein EPG5 and facilitate its targeting to late endosomes/lysosomes. In Wdr45 Wdr45b-deficient cells, the formation of tether-SNARE fusion machinery is compromised. The macroautophagy/autophagy deficiency in wdr45 wdr45b DKO cells is ameliorated by suppression of O-GlcNAcylation, which promotes autophagosome maturation. Thus, our results provide insights into the pathogenesis of WDR45- and WDR45B-related neurological diseases.During spliceosome assembly, interactions that bring the 5' and 3' ends of an intron in proximity are critical for the production of mature mRNA. Here, we report synergistic roles for the stem-loops 3 (SL3) and 4 (SL4) of the human U1 small nuclear RNA (snRNA) in maintaining the optimal U1 snRNP function, and formation of cross-intron contact with the U2 snRNP. We find that SL3 and SL4 bind distinct spliceosomal proteins and combining a U1 snRNA activity assay with siRNA-mediated knockdown, we demonstrate that SL3 and SL4 act through the RNA helicase UAP56 and the U2 protein SF3A1, respectively. In vitro analysis using UV crosslinking and splicing assays indicated that SL3 likely promotes the SL4-SF3A1 interaction leading to enhancement of A complex formation and pre-mRNA splicing. Overall, these results highlight the vital role of the distinct contacts of SL3 and SL4 in bridging the pre-mRNA bound U1 and U2 snRNPs during the early steps of human spliceosome assembly.Breastfeeding is a health promoting social behavior but statistics suggest a persistent disparity of lower rates among African American mothers. The Theory of Normative Social Behavior (TNSB) explains when and how norms influence behaviors, but has produced inconsistent results with respect to proposed moderators group identity and injunctive norms (IN), limiting its predictive value in diverse cultural groups. Cultural norms are one of many influences on breastfeeding behaviors, yet little is known about their mechanisms of influence. The TNSB has not been tested in the breastfeeding context or within an exclusively African American cultural group. Given this knowledge gap, a survey of 528 African American mothers in the Washington, D.C. area was conducted to test the moderating effects of IN and subjective norms (SN) and social identity on the descriptive norms (DN) to intentions relationship as predicted by the TNSB. Structural equation modeling was used to show that when controlling for education and breastfeeding history, norms significantly predicted 26.4% of the variance in breastfeeding intentions. SN and DN interacted negatively to enhance breastfeeding intentions. Latent profile analysis using ethnic pride, collectivism, and religiosity scales detected four profiles of African American social identity. Social identity profile membership was a significant moderator on the DN to intentions pathway in the structural equation model. Profiles with the highest ethnic pride were significantly influenced by DN to intend to breastfeed. Implications from this study for public health intervention and communication messaging are discussed.The year 2020 will be synonymous with the coronavirus disease 2019 (COVID-19) for many global citizens. Millions have died from and tens of millions more have been infected globally by the COVID-19 pandemic. This has led to an urgent search for COVID-19 vaccines and treatments by the scientific and political communities and civil society. Through elements of events study and document and critical discourse analysis, this paper investigates the COVID-19 vaccines' regulatory emergency use authorisation and/or conditional marketing authorisation (regulatory authorisation) regimes and the contestations thereof. The key finding is that there was a regulatory authorisation rush, with at least 62, mostly high-income countries, doing so in 40 days from 2 December 2020-10 January 2021. This has led to one senior USA official describing the United Kingdom pioneer regulatory authorisation of the Pfizer-BioNTech vaccine as 'too quick'. https://www.selleckchem.com/ Regulatory authorisation regimes took place amid severe civil society contestations and appropriate political pressure. The paper recommends that as the COVID-19 vaccines' regulatory authorisation continue in 2021, national vaccines and treatments regulatory bodies must be informed by science, with governments, civil society, politicians and other key stakeholders taking responsibility to educate the masses and continue taking the necessary precautions.
