THE EFFECT OF COVID-19 PANDEMIC ON DEATH ANXIETY OF NURSING STUDENTS

Background: It is required to determine death anxiety of nursing students so that they who will become healthcare professionals can cope with the fast-spreading and high-mortality diseases such as COVID-19 infection upon graduation, can communicate with infected and dying patients, and can provide patients with the necessary support and care. The purpose of this study is to determine the death anxiety experienced by nursing students due to COVID-19, the related factors. Subjects and methods: This descriptive and correlational study was completed between June and September 2020. The data were collected by using the Socio-demographic and COVID-19 Pandemic Information Form and Death Anxiety Scale (DAS). The student nurses who agreed to participate in the study were asked to fill out an online questionnaire that was sent by the researchers. The study was conducted with 115 nursing students. Results: The DAS mean scores of the nursing students were found to be 8.01+-1,96. When the correlation between DAS scores of the nursing students and their knowledge and attitudes regarding COVID-19 pandemic was examined, it was determined that as their anxiety levels about transmission of coronavirus increased, DAS scores also increased (p=0.037). The scores of death anxiety scale decreased as the level of students\u27 attention to events other than coronavirus, their level of comforting themselves and their belief mentioning that they would heal if they catch coronavirus increased (p<0.05). No statistically significant correlation was found between DAS scores and other knowledge and attitudes of nursing students regarding COVID-19 pandemic (p<0.05). Conclusion: It would be an effective method to provide the training to nursing students, in order to change their negative attitudes and awareness towards COVID-19 related death anxiety and to improve their coping skills for death anxiety and help to reduce the burden of anxiety

One Juliet and four Romeos: VeA and its methyltransferases

Fungal secondary metabolism has become an important research topic with great biomedical and biotechnological value. In the postgenomic era, understanding the diversity and the molecular control of secondary metabolites (SMs) are two challenging tasks addressed by the research community. Discovery of the LaeA methyltransferase 10 years ago opened up a new horizon on the control of SM research when it was found that expression of many SM gene clusters is controlled by LaeA. While the molecular function of LaeA remains an enigma, discovery of the velvet family proteins as interaction partners further extended the role of the LaeA beyond secondary metabolism. The heterotrimeric VelB–VeA–LaeA complex plays important roles in development, sporulation, secondary metabolism, and pathogenicity. Recently, three other methyltransferases have been found to associate with the velvet complex, the LaeA-like methyltransferase F and the methyltransferase heterodimers VipC–VapB. Interaction of VeA with at least four methyltransferase proteins indicates a molecular hub function for VeA that questions: Is there a VeA supercomplex or is VeA part of a highly dynamic cellular control network with many different partners

Membrane-Bound Methyltransferase Complex VapA-VipC-VapB Guides Epigenetic Control of Fungal Development

Epigenetic and transcriptional control of gene expression must be coordinated in response to external signals to promote alternative multicellular developmental programs. The membrane-associated trimeric complex VapA-VipC-VapB controls a signal transduction pathway for fungal differentiation. The VipC-VapB methyltransferases are tethered to the membrane by the FYVE-like zinc finger protein VapA, allowing the nuclear VelB-VeA-LaeA complex to activate transcription for sexual development. Once the release from VapA is triggered, VipCVapB is transported into the nucleus. VipC-VapB physically interacts with VeA and reduces its nuclear import and protein stability, thereby reducing the nuclear VelB-VeA-LaeA complex. Nuclear VapB methyltransferase diminishes the establishment of facultative heterochromatin by decreasing histone 3 lysine 9 trimethylation (H3K9me3). This favors activation of the regulatory genes brlA and abaA, which promote the asexual program. The VapA-VipCVapB methyltransferase pathway combines control of nuclear import and stability of transcription factors with histone modification to foster appropriate differentiation responses

Control of development, secondary metabolism and light-dependent carotenoid biosynthesis by the velvet complex of Neurospora crassa

Neurospora crassa is an established reference organism to investigate carotene biosynthesis and light regulation. However, there is little evidence of its capacity to produce secondary metabolites. Here, we report the role of the fungal-specific regulatory velvet complexes in development and secondary metabolism (SM) in N. crassa. Three velvet proteins VE-1, VE-2, VOS-1, and a putative methyltransferase LAE-1 show light-independent nucleocytoplasmic localization. Two distinct velvet complexes, a heterotrimeric VE-1/VE-2/LAE-1 and a heterodimeric VE-2/VOS-1 are found in vivo. The heterotrimer-complex, which positively regulates sexual development and represses asexual sporulation, suppresses siderophore coprogen production under iron starvation conditions. The VE-1/VE-2 heterodimer controls carotene production. VE-1 regulates the expression of .15% of the whole genome, comprising mainly regulatory and developmental features. We also studied intergenera functions of the velvet complex through complementation of Aspergillus nidulans veA, velB, laeA, vosA mutants with their N. crassa orthologs ve-1, ve-2, lae-1, and vos-1, respectively. Expression of VE-1 and VE-2 in A. nidulans successfully substitutes the developmental and SM functions of VeA and VelB by forming two functional chimeric velvet complexes in vivo, VelB/VE-1/LaeA and VE-2/VeA/LaeA, respectively. Reciprocally, expression of veA restores the phenotypes of the N. crassa ve-1 mutant. All N. crassa velvet proteins heterologously expressed in A. nidulans are localized to the nuclear fraction independent of light. These data highlight the conservation of the complex formation in N. crassa and A. nidulans. However, they also underline the intergenera similarities and differences of velvet roles according to different life styles, niches and ontogenetic processes
