Sleep

January 2025

UR2NF-Neuropsychology and Functional Neuroimaging Research Unit affiliated at CRCN - Centre for Research in Cognition and Neurosciences and UNI - ULB Neuroscience Institute, Université Libre de Bruxelles (ULB), Brussels, Belgium.

Enhancing the retention of recent memory traces through sleep reactivation is possible via Targeted Memory Reactivation (TMR), involving cueing learned material during post-training sleep. Evidence indicates detectable short-term microstructural changes in the brain within an hour after motor sequence learning, and post-training sleep is believed to contribute to the consolidation of these motor memories, potentially leading to enduring microstructural changes. In this study, we explored how TMR during post-training sleep affects performance gains and delayed microstructural remodeling, using both standard Diffusion Tensor Imaging (DTI) and advanced Neurite Orientation Dispersion & Density Imaging (NODDI).

The first of several phase 3 trials examining efficacy in relapsing MS has not been able to demonstrate a significant benefit and has also raised important safety concerns. More results are on their way and it will be important to understand whether the safety signals identified are drug- or class-specific and whether other BTKi also fail to reach their endpoints for relapsing MS. However, as reported in preliminary data for another BTKi, it may be that they will have more of a role in progressive disease as hinted by the unraveling of relevant molecular mechanisms and pathways.

Light plays an important role in determining the L-ascorbate (AsA) pool size in plants, primarily through the transcriptional regulation of AsA metabolism-related genes. However, the specific mechanism of transcriptional induction responsible for light-dependent AsA biosynthesis remains unclear. In this study, we used a promoter sequence containing light-responsive motifs from GDP-L-galactose phosphorylase 2 (RrGGP2), a key gene involved in AsA overproduction in Rosa roxburghii fruits, to identify participating transcription factors.

Cardiac amyloidosis represents a unique disease process characterized by amyloid fibril deposition within the myocardial extracellular space. Advances in multimodality cardiac imaging enable accurate diagnosis and facilitate prompt initiation of disease-modifying therapies. Furthermore, rapid advances in multimodality imaging have enriched understanding of the underlying pathogenesis, enhanced prognostication, and resulted in the development of imaging-based markers that reflect the amyloid burden, which is of increasing importance when assessing the response to treatment.

The global changes from 2001 that elevated substantially modified cell therapies to the definition of "medicinal product" have been the catalyst for the dramatic expansion of the field to its current and future commercial success. Europe was the first to incorporate human somatic cells into drug legislation with the medicines directive of 2001 (2001/83/EC), which led to the development of the term "advanced therapy medicinal products" (ATMPs) to cover all substantially modified products, tissue-engineered products and somatic cells that are not substantially modified but that are used non-homologously. For convenience, I use the term "ATMPs" throughout this review.

Manipulating the optical landscape of single quantum dots (QDs) is essential to increase the emitted photon output, enhancing their performance as chemical sensors and single-photon sources. Micro-optical structures are typically used for this task, with the drawback of a large size compared to the embedded single emitters. Nanophotonic architectures hold the promise to modify dramatically the emission properties of QDs, boosting light-matter interactions at the nanoscale, in ultracompact devices.

In both nature and industry, aerosol droplets contain complex mixtures of solutes, which in many cases include multiple inorganic components. Understanding the drying kinetics of these droplets and the impact on resultant particle morphology is essential for a variety of applications including improving inhalable drugs, mitigating disease transmission, and developing more accurate climate models. However, the previous literature has only focused on the relationship between drying kinetics and particle morphology for aerosol droplets containing a single nonvolatile component.

Transcriptional regulation of the piRNA pathway by Ovo in animal ovarian germ cells.

Genes Dev

December 2024

Cancer Research UK Cambridge Institute, Li Ka Shing Centre, University of Cambridge, Cambridge CB2 0RE, United Kingdom

The gene-regulatory mechanisms controlling the expression of the germline PIWI-interacting RNA (piRNA) pathway components within the gonads of metazoan species remain largely unexplored. In contrast to the male germline piRNA pathway, which in mice is known to be activated by the testis-specific transcription factor A-MYB, the nature of the ovary-specific gene-regulatory network driving the female germline piRNA pathway remains a mystery. Here, using as a model, we combined multiple genomics approaches to reveal the transcription factor Ovo as regulator of the germline piRNA pathway in ovarian germ cells.
