STK19 positions TFIIH for cell-free transcription-coupled DNA repair.

In transcription-coupled nucleotide excision repair (TC-NER), stalled RNA polymerase II (RNA Pol II) binds CSB and CRL4, which cooperate with UVSSA and ELOF1 to recruit TFIIH. To explore the mechanism of TC-NER, we recapitulated this reaction in vitro. When a plasmid containing a site-specific lesion is transcribed in frog egg extract, error-free repair is observed that depends on CSB, CRL4, UVSSA, and ELOF1.

Improving the sustainability and quality of kidney health care through life cycle assessments, quality improvement, education and technical innovations: the KitNewCare approach.

The European Union (EU)-funded KitNewCare consortium aims to create and manage a comprehensive EU-wide programme focusing on sustainability in Kidney Care. Around 850 million people have chronic kidney disease (CKD) worldwide and by 2030, 6 million will need kidney replacement therapy, mainly haemodialysis. As the world population gets older, projections for the end of the century worsen.

Accumulation of F-actin drives brain aging and limits healthspan in Drosophila.

The actin cytoskeleton is a key determinant of cell structure and homeostasis. However, possible tissue-specific changes to actin dynamics during aging, notably brain aging, are not understood. Here, we show that there is an age-related increase in filamentous actin (F-actin) in Drosophila brains, which is counteracted by prolongevity interventions.

Genomes of Microtus Rodents Highlight the Importance of Olfactory and Immune Systems in Their Fast Radiation.

The characterization of genes and biological functions underlying functional diversification and the formation of species is a major goal of evolutionary biology. In this study, we investigated the fast radiation of Microtus voles, one of the most speciose group of mammals, which shows strong genetic divergence despite few readily observable morphological differences. We produced an annotated reference genome for the common vole, Microtus arvalis, and resequenced the genomes of 10 different species and evolutionary lineages spanning the Microtus speciation continuum.

Characterization of Flow with a V-Shaped NMR Sensor.

Quality control in a production plant shows its maximum potential in the form of inline measurements. Defects and imperfections can be detected early and directly, and waste and costs can be reduced. Nuclear Magnetic Resonance offers a wide range of applications but requires dedicated adaptation to the respective process and material conditions.
