Zebrafish bioassay-guided isolation of antiseizure compounds from the Cameroonian medicinal plant Cyperus articulatus L.

Background: Epilepsy is a chronic neurological disorder affecting more than 50 million people worldwide, of whom 80% live in low- and middle-income countries. Due to the limited availability of antiseizure drugs (ASDs) in these countries, medicinal plants are the first-line treatment for most epilepsy patients. In Cameroon, a decoction of Cyperus articulatus L.

[Radiation Exposition of preparations of radiopharmaceuticals in routinely use, measured with optical-stimulated luminescence (OSL) dosimeters].

Aim:  Because of the new regulation of the radiation protection in Germany in 2018 (Strahlenschutzverordnung) it was meaningful to calculate an overview of the radiation exposition of the personal in the radiopharmaceutical "Hotlab". The regulation demands that the radiation exposition must be minimized, documented and reduced to an optimized level. In the Klinik und Poliklinik für Nuklearmedizin at the University Hospital of Dresden measurements were done with optical-stimulated luminescence (OSL) dosimeters.

The Foundation for the National Institutes of Health Biomarkers Consortium: Past Accomplishments and New Strategic Direction.

The Foundation for the National Institutes of Health (FNIH) Biomarkers Consortium (BC) is a public-private partnership that aims to facilitate drug development with biomarkers across a range of therapeutic areas. The BC is organized to address specific precompetitive biomarker projects, giving participating stakeholders a role in the design and conduct of projects and making the results freely public. Ultimately, the goals of the BC are to accelerate the development of new medicines, inform regulatory decision making, and improve patient care.

Trends in Modern Drug Discovery.

Drugs discovered by the pharmaceutical industry over the past 100 years have dramatically changed the practice of medicine and impacted on many aspects of our culture. For many years, drug discovery was a target- and mechanism-agnostic approach that was based on ethnobotanical knowledge often fueled by serendipity. With the advent of modern molecular biology methods and based on knowledge of the human genome, drug discovery has now largely changed into a hypothesis-driven target-based approach, a development which was paralleled by significant environmental changes in the pharmaceutical industry.
