The yeast Xanthophyllomyces dendrorhous synthesizes astaxanthin, a high-value carotenoid with biotechnological relevance in the nutraceutical and aquaculture industries. However, enhancing carotenoid production through strain engineering remains an ongoing challenge. Recent studies have demonstrated that carotenogenesis in X.

Article Synopsis
  • Migrants and refugees often struggle with mental health issues but have limited access to proper services, prompting this study to explore ways to deliver psychological support in Colombia using a group intervention called gPM+.
  • The study compared two training methods for nonspecialists delivering gPM+: one receiving support from a psychologist and the other from a trained nonspecialist, enrolling 128 distressed adult women in the process.
  • Results showed higher attendance in the psychologist-supported group, but the trained nonspecialist group was more cost-effective and maintained fidelity in delivering the program, highlighting the potential for using community-based methods for mental health interventions.

Background: Communication and collaboration among health care professionals during bedside rounds improve patient outcomes and nurses' and physicians' satisfaction.

Objectives: To determine barriers to nurse-physician communication during bedside rounds and identify opportunities to improve nurse-physician collaboration at an academic medical center.

Methods: A survey with Likert-scale and open-ended questions regarding professional attitudes toward nurse-physician communication was administered to 220 nurses and physicians in medical-surgical units to assess perceptions of participation in bedside rounds.

The sterol regulatory element-binding protein (SREBP) pathway is an integral cellular mechanism that regulates lipid homeostasis, in which transcriptional activator SREBPs regulate the expression of various genes. In the carotenogenic yeast , Sre1 (the yeast SREBP homolog) regulates lipid biosynthesis and carotenogenesis, among other processes. Despite the characterization of several components of the SREBP pathway across various eukaryotes, the specific elements of this pathway in remain largely unknown.

Purpose: To assess the reliability of excising residual breast cancer lesions after neoadjuvant systemic therapy (NAST) using a previously localized paramagnetic seed (Magseed®) and the subsequent use of contrast-enhanced spectral mammography (CESM) to evaluate response.

Methods: Observational, prospective, multicenter study including adult women (> 18 years) with invasive breast carcinoma undergoing NAST between January 2022 and February 2023 with non-palpable tumor lesions at surgery. Radiologists marked tumors with Magseed® during biopsy before NAST, and surgeons excised tumors guided by the Sentimag® magnetometer.
