<P>Bacteriophytochromes (BphP) are phytochrome-like light sensing proteins in bacteria, which use biliverdin as a chromophore. In order to study the biochemical properties of the DrBphP protein, five (2B8, 2C11, 3B2, 3D2, and 3H7) anti-DrBphP monoclonal antibodies were produced through the immunization of mice with purified full-length DrBphP and DrBphN (1-321 amino acid) proteins, and epitope mapping was then carried out. Among the five antibodies, 2B8 and 2C11 preferentially recognized the N-terminal region of BphP whereas 3B2, 3D2, and 3H7 showed preference for the C-terminal region. We performed further epitope mapping using recombinant truncated BphP proteins to narrow down their target sequences. The results demonstrated that each of the five monoclonal antibodies recognized different regions on the DrBphP protein. Additionally, epitopes of 2B8 and 3H7 antibodies were discovered to be shorter than 10 amino acids (2B8: RDPLPFFPP, 3H7: PGEIEEA). These two antibodies with such specific recognition epitopes could be especially valuable for developing new peptide tags for protein detection and purification.</P>

Purpose: This study aimed to explore the knowledge and performance of sleep hygiene among nurses with shift work schedules and examine the influence on sleep disturbance. Methods: A total of 199 shift-work nurses from a tertiary hospital were included in the study. To examine the knowledge and performance of sleep hygiene, the participants were asked to respond to a self-reported survey. To assess sleep disturbance, the General Sleep Disturbance Scale was used. Descriptive statistics and multiple linear regression were applied using the SPSS/WIN 21.0 program to analyze the data. Results: Both the knowledge and performance of sleep hygiene among nurses with shift work schedules were measured at a moderate level. Nurses’ knowledge and the performance of sleep hygiene was not significantly associated with sleep disturbance, whereas age, experience with shift-working, and perceived health status were significantly associated. Conclusion: Strategies for providing more accurate information and motivating better sleep hygiene would help to enhance sleep hygiene in nurses with shift work schedules. Further studies examining the association of knowledge and the performance of sleep hygiene with sleep disturbances in nurses with shift work schedules are needed.
