Amyloid-related changes in fluency in patients with subjective cognitive decline.

Introduction: We examined semantic and phonemic fluency in individuals with subjective cognitive decline (SCD) in relation to amyloid status and clinical progression.

Methods: A total of 490 individuals with SCD (62 ± 8 years, 42% female, 28% amyloid-positive, 17% clinical progression) completed annual fluency assessments (mean ± SD follow-up 4.3 ± 2.

The effect of early warning scoring systems on adverse outcome in surgical patients: A systematic review.

Background: An early warning scoring system aims to detect clinical deterioration at an early stage and prevent failure-to-rescue in hospitalized patients. In this systematic review we studied the effect of an early warning scoring system on adverse outcome in surgical patients.

Methods: This review was conducted and reported according to PRISMA and the protocol of this review is registered at PROSPERO, under the registration number CRD42018107799.

Silent silencers: Leave no trace.

The regulatory mechanisms of silencers have remained poorly understood. In this issue, Hofbauer et al. conduct a genome-wide screen in Drosophila melanogaster and reveal three silencer types that appear to work alone-without the need for combinatorial action, traditional chromatin marks, or open chromatin regions.

Precision Activity-Based α-Amylase Probes for Dissection and Annotation of Linear and Branched-Chain Starch-Degrading Enzymes.

α-Amylases are the workhorse enzymes of starch degradation. They are central to human health, including as targets for anti-diabetic compounds, but are also the key enzymes in the industrial processing of starch for biofuels, corn syrups, brewing and detergents. Dissection of the activity, specificity and stability of α-amylases is crucial to understanding their biology and allowing their exploitation.

Comparing robust proton versus online adaptive photon radiotherapy for short-course treatment of rectal cancer.

Background And Purpose: Image-guided proton beam therapy (IG-PBT) and cone-beam CT (CBCT)-based online adaptive photon radiotherapy (oART) have potentials to restrict radiation toxicity. They are both hypothesised to reduce therapy limiting bowel toxicity in the multimodality treatment of locally advanced rectal cancer (LARC). This study aimed to quantify the difference in relevant dose-volume metrics for these modalities.
