Ultrasound assisted extraction of amino acids and nucleobases from clay minerals and astrobiological samples.

The study of organic molecules in meteorite and return samples allows for the understanding of the chemistry that undergoes in our Solar System. The present work aims at studying ultrasound assisted extraction technique as effective extraction method for these molecules in extraterrestrial samples and analogs. Optimal conditions were selected from the investigation of ultrasonic frequency, irradiation duration and solvent effects on amino acids, nucleobases and dipeptides extraction yields from a model clay-rich mineral matrix.

Medicinal Product Development and Regulatory Agilities Implemented During the Early Phases of the COVID-19 Pandemic: Experiences and Implications for the Future-An Industry View.

The COVID-19 pandemic caused considerable disruption to the development, regulatory evaluation, production, and distribution of medicinal products. Key healthcare stakeholders were under pressure to develop and review medicinal products to address the health emergency, while preserving the continuity of activities to ensure patient access to other medicinal products. In the light of this challenging situation, the National Regulatory Authorities (NRAs) and the biopharmaceutical industry applied and utilized product development and regulatory agilities to accelerate the development and authorization of safe, effective and quality COVID-19 vaccines and treatments as well as other non-COVID-19 medicinal products.

Risk Factors of Progression in Low-tumor Burden Follicular Lymphoma Initially Managed by Watch and Wait in the Era of PET and Rituximab.

Patients (pts) with asymptomatic low-burden follicular lymphoma (FL) are usually observed at diagnosis. Time to lymphoma treatment (TLT) initiation can however be very heterogeneous and risk factors of progression are poorly studied. Our study evaluated 201 pts with grade 1-3a low-tumor burden FL diagnosed in four French centers between 2010 and 2020 and managed by a watch and wait strategy in real-life settings.

Metoclopramide Test in Hyperprolactinemic Women With Polycystic Ovarian Syndrome: Old Wine Into New Bottles?

Introduction: Polycystic ovarian syndrome (PCOS) is the most frequent etiology of anovulation, hyperandrogenism and infertility in women. Its pathophysiology remains poorly elucidated. Hyperprolactinemia (hPRL) is common in women of reproductive age and may partially mimic the clinical phenotype of PCOS.
