The present research, enlightened by the dynamic approach to language learning, aimed to trace the co-development of English as a foreign language (EFL) learners' perseverance of effort (PE) and consistency of interest (CI), the two subdomains of grit, over a course time. To this aim, a factor of curves model (FCM) was employed to trace the covariance of the subdomains of L2 grit longitudinally over time; to explore how changes in PE and CI are affected by their initial states; and to what extent the variations in PE and CI are explained by the underlying global factor of L2 grit. For data collection, the L2 grit scale was used with 1,384 adult EFL learners in four measurement occasions.

- Rhizodeposition significantly influences carbon cycling in soil, but accurately measuring it in natural settings has been challenging.
- Using a C-CO pulse-labeling technique, researchers quantified the role of rhizodeposition in below-ground respiration in a grassland environment.
- The study found that rhizodeposit decomposition contributes 7-31% to total respiration and is affected by drought and nitrogen treatments, showcasing the complexity of carbon dynamics in these ecosystems.
Purpose: Acneiform rash, a common toxicity of epidermal growth factor receptor inhibitors (EGFRIs), can cause patient discomfort, warranting changes in treatment. This study investigated the safety, tolerability, and efficacy of a novel doxycycline foam, FDX104 4%, for managing EGFRI-related skin toxicity.
Methods: This was an exploratory phase 2, randomized, double-blind, placebo-controlled study.
Objective: Our objective was to demonstrate the safety, tolerability, and efficacy of a minocycline foam, FMX103, in the treatment of moderate-to-severe facial papulopustular rosacea.
Methods: This was a phase II, randomized, double-blind, multicenter study. Healthy subjects aged ≥ 18 years with moderate-to-severe rosacea that had been diagnosed ≥ 6 months previously and with ≥ 12 inflammatory facial lesions were randomized (1:1:1) to receive once-daily 1.
