The Laboratory Opossum () Is a Unique Model for Research on Zika Virus: Robust Immune Response, Widespread Dissemination, and Long-Term Persistence.

The Zika virus (ZIKV) epidemic elicited a rapid commitment to the development of animal models for ZIKV research. Non-human primates (NHPs) and mice have made significant contributions to this research, but NHPs are expensive, have a long gestation period, and are available only in small numbers; non-genetically modified mice are resistant to infection. To address these deficiencies, we have established the laboratory opossum, , as a small animal model that complements the mouse and monkey models.

Unlocking Testosterone Production by Biotransformation: Engineering a Fungal Model of Strain Deficient in Steroid 11α-Hydroxylase Activity and Expressing 17β-Hydroxysteroid Dehydrogenase Enzyme as Proof of Concept.

Testosterone holds significant medical and economic importance, with the global market for testosterone replacement therapies valued at approximately USD 1.9 billion in 2023. This hormone is essential for the development and maintenance of male sexual characteristics as well as bone and muscle health.

The Impact of "Close Margins" in HPV-Associated Oropharyngeal Squamous Cell Carcinoma Treated with TORS.

Objective: Margin distance is a significant prognosticator in oral cavity cancer but its role in HPV-related oropharyngeal squamous cell carcinoma [HPV(+)OPSCC] remains unclear. Here, we investigate the impact of margin distance on locoregional recurrence in HPV(+)OPSCC.

Study Design: This is a retrospective cohort study of surgically treated HPV(+)OPSCC patients.

Effects of prior air pollution exposure on functional recovery after a myocardial infarction.

Air pollution is a major cardiovascular risk factor leading to higher rates of heart failure and myocardial infarction (MI), but its effects on functional recovery after an MI remain unknown. Cardiac rehabilitation is a cornerstone of post-MI care and leads to better performance and quality of life, but its benefits may be hampered in heavily polluted environments. To assess the effect of different pollutants on post-MI rehabilitation, we included 137 post-MI patients from 7 Spanish hospitals that were enrolled in a cardiac rehabilitation program who underwent two cardiopulmonary exercise tests (CPET) within a 12-week period.

Symbolic dynamics of joint brain states during dyadic coordination.

We propose a novel approach to investigate the brain mechanisms that support coordination of behavior between individuals. Brain states in single individuals defined by the patterns of functional connectivity between brain regions are used to create joint symbolic representations of brain states in two or more individuals to investigate symbolic dynamics that are related to interactive behaviors. We apply this approach to electroencephalographic data from pairs of subjects engaged in two different modes of finger-tapping coordination tasks (synchronization and syncopation) under different interaction conditions (uncoupled, leader-follower, and mutual) to explore the neural mechanisms of multi-person motor coordination.
