    Introduction: In response to the coronavirus disease (COVID-19) pandemic, most universities experienced drastic operational changes with shifts to online learning, work-from-home policies, and social distancing measures. These changes have caused concern for social isolation and mental health. Purpose: This cross-sectional study explores differences in COVID-19 experiences, behaviors, beliefs, and well-being among students and employees (faculty and staff) at a rural Appalachian university. Methods: Data were collected with an online anonymous survey in September-October 2020 using convenience sampling. The survey measured multiple domains including COVID-19-related 1) beliefs, 2) symptoms and diagnoses, 3) exposure and preventive behavior, and 4) social, mental, and financial health. Chi-square tests and linear regression models were used to determine differences in survey responses between students and employees. Results: The final sample used for analysis included 416 respondents. The majority of respondents believed COVID-19 was a serious disease and followed mask and social distancing guidelines, although employees were more likely to adhere to mask and social distancing guidelines compared to students. Most of the respondents (\u3e50%) reported feeling more stressed, anxious, and sad since the pandemic began. Students were more impacted by the pandemic compared to employees as measured by the mental, social, and financial impact scale. A limitation of this study was that convenience sampling was used instead of a probability sampling technique, which limits the inference that can be made from the results. Implications: There may be a need for greater mental health support among university employees and students. However, future studies should confirm these findings

This study aims to (1) determine the prevalence of ECP use among girls who have had sexual intercourse and (2) comparatively analyze their family and psychological profiles according to whether they have used ECPs. Methods:The sample of 1735 Spanish girls aged 15 to 18 came from a representative sample of the 2014 edition of the Health Behaviour in School-aged Children (HBSC) study. Of this sample, 398 girls had sexual intercourse and reported their ECP use. Data collection for the HBSC study was performed through an online questionnaire to which adolescents responded anonymously in school. Data analyses were descriptive and bivariate and were performed with the statistical program IBM SPSS Statistics 23.Results:The results demonstrated that 30.65% of girls who had sexual intercourse used ECPs. Noticeable differences in paternal knowledge and communication with the father were observed between girls who used the ECP at least once and those who did not use it. In contrast, differences between girls who used the ECP once and those who used it twice or more were pronounced with regard to parental knowledge, communication with parents, maternal affection,life satisfaction, sense of coherence and depression. Conclusions:This work demonstrates a high prevalence of ECP use and a more positive family and psychological profile for girls who used ECP once compared with those who used it twice or more.Peer reviewedFinal Published versio

    Localization of diphtheria toxin nuclease activity to fragment A.

    We describe a series of experiments that aimed to establish whether nuclease activity is actually associated with diphtheria toxin (DTx) and its A subunit (DTA), as we originally reported (M. P. Chang, R. L. Baldwin, C. Bruce, and B. J. Wisnieski, Science 246:1165-1168, 1989). Here we show that (i) trypsinization of DTx does indeed produce nucleolytically active DTA, (ii) reduction of electroeluted, unreduced, cleaved DTx (58 kDa) yields nuclease-active DTA (24 kDa), and (iii) fractionation of DTx and DTA by anion-exchange chromatography leads to coelution of nuclease activity with both forms of the toxin, even though each form elutes at a distinct salt concentration. In addition, we show that Escherichia coli-derived DTA also expresses nuclease activity. These studies confirm our initial assertion that the nuclease activity observed in DTx preparations is intrinsic to the DTA portion of DTx
