Maintenance and transformation of representational formats during working memory prioritization.

Nat Commun

September 2024

Department of Neuropsychology, Institute of Cognitive Neuroscience, Faculty of Psychology, Ruhr University Bochum, 44801, Bochum, Germany.

Visual working memory depends on both material-specific brain areas in the ventral visual stream (VVS) that support the maintenance of stimulus representations and on regions in the prefrontal cortex (PFC) that control these representations. How executive control prioritizes working memory contents and whether this affects their representational formats remains an open question, however. Here, we analyzed intracranial EEG (iEEG) recordings in epilepsy patients with electrodes in VVS and PFC who performed a multi-item working memory task involving a retro-cue.

Characterization of the angiomodulatory effects of Interleukin 11 cis- and trans-signaling in the retina.

J Neuroinflammation

September 2024

Eye Center, Medical Center, Faculty of Medicine, University of Freiburg, Klinik für Augenheilkunde, Kilianstrasse 5, 79106, Freiburg im Breisgau, Germany.

Article Synopsis
  • The study investigates the effects of IL-11, a member of the IL-6 cytokine family, on retinal angiogenesis, particularly in the context of proliferative diabetic retinopathy (PDR).
  • Findings show that IL-11 can have antiangiogenic effects when signaling directly (cis-signaling) and proangiogenic effects when interacting with soluble receptors (trans-signaling).
  • In vivo experiments indicated that both forms of signaling reduce retinal neovascularization and activate Müller cells, suggesting IL-11 influences different retinal cell types rather than just vascular endothelial cells.

ICU-Electroencephalogram Unit Improves Outcome in Status Epilepticus Patients: A Retrospective Before-After Study.

Crit Care Med

November 2024

Division of Intensive Care, Department or Anaesthesiology, Pharmacology, Intensive Care and Emergency Medicine Geneva University Hospitals, Faculty of Medicine, University of Geneva, Geneva, Switzerland.

Objectives: Continuous electroencephalogram (cEEG) monitoring is recommended for status epilepticus (SE) management in ICU but is still underused due to resource limitations and inconclusive evidence regarding its impact on outcome. Furthermore, the term "continuous monitoring" often implies continuous recording with variable intermittent review. The establishment of a dedicated ICU-electroencephalogram unit may fill this gap, allowing cEEG with nearly real-time review and multidisciplinary management collaboration.

Mitochondrial ribosomes (mitoribosomes) have undergone substantial evolutionary structural remodeling accompanied by loss of ribosomal RNA, while acquiring unique protein subunits located on the periphery. We generated CRISPR-mediated knockouts of all 14 unique (mitochondria-specific/supernumerary) human mitoribosomal proteins (snMRPs) in the small subunit to study the effect on mitoribosome assembly and protein synthesis, each leading to a unique mitoribosome assembly defect with variable impact on mitochondrial protein synthesis. Surprisingly, the stability of mS37 was reduced in all our snMRP knockouts of the small and large ribosomal subunits and patient-derived lines with mitoribosome assembly defects.

Bloodstream infections (BSI) are defined by the presence of viable bacteria or fungi, accompanied by systemic signs of infection. Choosing empirical therapy based solely on patient risk factors and prior antibiotic susceptibility test (AST) may lead to either ineffective treatment or unnecessarily broad-spectrum antibiotic exposure. In general, Clinical & Laboratory Standards Institute guideline-approved ASTs have a turnaround time of 48-72 h from sample to answer, a period that may result in a critical delay in the appropriate selection of therapy.
