Eukaryotic ribosome assembly is an intricate process that involves four ribosomal RNAs, 80 ribosomal proteins, and over 200 biogenesis factors that take part in numerous interdependent steps. This complexity creates a large genetic space in which pathogenic mutations can occur. Dead-end ribosome intermediates that result from biogenesis errors are rapidly degraded, affirming the existence of quality control pathway(s) that monitor ribosome assembly.

However, prostate cancer can develop into androgen-independent castration-resistant prostate cancer (CRPC) which is resistant to ADT. An alternative treatment strategy for CRPC can be targeting the epithelial-mesenchymal transition (EMT).

Perfectionism is a vulnerability factor for a wide array of psychopathology. Despite much evidence suggesting dysregulated stress response as an intermediary process that links perfectionism to psychopathology, the lack of a cross-lagged examination deterred researchers from making causal interpretations. This study examined the directionality of effects among perfectionism dimensions, stress reactivity, and depression.

Using a random split sample of 1199 young adult university students, results of exploratory factor analyses (EFA) identified a four-factor structure in the COVID-19 Stressors Questionnaire (C19SQ), which were labeled Resource Constraints, Social Restrictions, Future Uncertainty, and Health Concerns. This model was supported by a confirmatory factor analysis (CFA) when run on the other split sample of 1139 university students.

Objective: College drinking is a significant individual and societal problem, and thus, identifying risk factors to alcohol-related problems has been an important line of inquiry. Adding to this rich literature, the current study examined whether perfectionism dimensions were associated with alcohol-related problems and whether a poor self-regulation process linked these associations.
Participants: A total of 410 university students completed measures pertaining to perfectionism, procrastination, and negative consequences of alcohol use.
Objective: This study examined the differences in first-year college students' daily change trajectories in subjective happiness, depression, anxiety, stress, and state mindfulness.
Method: A 5-day, online mindfulness-based intervention (MI) condition and stress management (SM) condition were employed in 247 first-year college students.
Results: Students in both the MI and SM conditions displayed similar significant linear declines in anxiety and stress, but there were significant differences between the two conditions, including: (1) the MI condition showing a significant linear increase in subjective happiness compared with no change in the SM condition and (2) the SM condition showed a significant linear decrease in depression compared to no significant change in the MI condition.
We explored latent profiles based on mindfulness and difficulties in emotion regulation scores, and investigated each profiles' relations to work-family-school conflict (WFSC). A total of 194 first year college students (64.4% women) participated in this study.

Of particular interest was the examination of a moderator of delivery method (face-to-face vs. online) in testing the effectiveness of psychological interventions.

International (n = 434) and domestic (n = 387) students completed the Advisory Working Alliance Inventory (AWAI-S; Schlosser & Gelso, 2001) and measures of advising experiences, perceived academic stress, and desire to change advisor.

Despite the challenges, ensuring that a psychological distress measure works effectively has considerable potential value for assessment purposes. The current study evaluates the measurement properties of a short 10-item version of Radloff's Center for Epidemiologic Studies Depression Scale (CES-D).

In Study 1, a confirmatory factor analysis was performed on the Korean version with 27 items for 151 Korean college students, but the model fit was poor. Subsequently, an exploratory factor analysis was conducted, and the results yielded three factors as found in Hewitt, et al.
