Gene regulation by convergent promoters.

Convergent transcription, that is, the collision of sense and antisense transcription, is ubiquitous in mammalian genomes and believed to diminish RNA expression. Recently, antisense transcription downstream of promoters was found to be surprisingly prevalent. However, functional characteristics of affected promoters are poorly investigated.

Sex-related functional outcome after periacetabular osteotomy in mild to severe hip dysplasia.

Aims: Periacetabular osteotomy (PAO) is well established for acetabular reorientation and has shown successful improvement in patient-reported outcome measures (PROMs). Nevertheless, studies focusing on postoperative outcomes related to patient individual factors are still underrepresented. Therefore, this study aimed to analyze the functional outcome and activity level in relation to patient sex with a minimum follow-up of two years after PAO for mild to severe hip dysplasia.

Adaptive Laboratory Evolution of Flavin Functionality Identifies Dihydrolipoyl Dehydrogenase as One of the Critical Points for the Activity of 7,8-Didemethyl-Riboflavin as a Surrogate for Riboflavin in .

Riboflavin analogs lacking one methyl group (7α or 8α) can still serve as a surrogate for riboflavin in riboflavin-deficient microorganisms or animals. The absence of both methyl groups at once completely abolishes this substitution capability. To elucidate the molecular mechanisms behind this phenomenon, we performed an adaptive laboratory evolution experiment (in triplicate) on an strain auxotrophic for riboflavin.

Molecular Simulation Study of All-Silica Zeolites for the Adsorptive Removal of Airborne Chloroethenes.

Chloroethenes (CHCl with = 1, 2, 3, 4) are produced and consumed in various industrial processes. As the release of these compounds into air, water, and soils can pose significant risks to human health and the environment, different techniques have been exploited to prevent or remediate chloroethene pollution. Although several previous experimental and computational studies investigated the removal of chloroethenes using zeolite adsorbents, their structural diversity in terms of pore size and pore topology has hardly been explored so far.

Serially quantifying TERT rearrangement breakpoints in circulating tumor DNA enables minimal residual disease monitoring in patients with neuroblastoma.

Telomerase is reactivated by genomic TERT rearrangements in ~30% of diagnosed high-risk neuroblastomas. Dismal patient prognosis results if the RAS/MAPK/ALK signaling transduction network also harbors mutations. We present a liquid biopsy-based monitoring strategy for this particularly vulnerable pediatric patient subgroup, for whom real-time molecular diagnostic tools are limited to date.
