ackground: Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. Objective: This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. Methods: A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. Results: The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they we...

Here, we present an in vitro protocol to assay mRNA translation inhibitors using the fluorescent assembly of split-GFP for translation test (FAST), based on the small fragment GFP11 binding to GFP1-10fast. We detail the expression and purification of the GFP1-10fast protein, DNA template amplification, in vitro GFP11-tagged CspA synthesis, FAST detection of the GFP11-tagged protein, and optional recovery of the fluorescent complex. In vitro synthesis of GFP11 maximizes the molar yield of synthesized proteins, providing enhanced sensitivity to test translation inhibitors. For complete details on the use and execution of this protocol, please refer to Pham et al.
