ZIC1 is a context-dependent medulloblastoma driver in the rhombic lip.

Nat Genet

January 2025

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Ontario, Canada.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

Bona fide diminished ovarian reserve or profound ovarian suppression by long-term oral contraceptive use?

BMJ Case Rep

January 2025

Obstetrics and Gynecology; Divison of Reproductive Endocrinology and Infertility, University of Toronto, Toronto, Ontario, Canada

Combined oral contraceptives (COCs) are widely used by reproductive-aged women. Current data suggest that long-term use of COCs can suppress ovarian reserve markers, including anti-mullerian hormone and antral follicle count, which may negatively impact ovarian response and oocyte yield in patients undergoing planned oocyte cryopreservation to preserve future reproductive potential. Discontinuation of COCs can improve ovarian stimulation outcomes, though the ideal duration of cessation is unknown.

Characterizing features affecting local ancestry inference performance in admixed populations.

Am J Hum Genet

December 2024

Department of Molecular and Human Genetics, Baylor College of Medicine, Houston, TX 77030, USA; The Jan and Dan Duncan Neurological Research Institute, Texas Children's Hospital, Houston, TX 77030, USA. Electronic address:

In recent years, significant efforts have been made to improve methods for genomic studies of admixed populations using local ancestry inference (LAI). Accurate LAI is crucial to ensure that downstream analyses accurately reflect the genetic ancestry of research participants. Here, we test analytic strategies for LAI to provide guidelines for optimal accuracy, focusing on admixed populations reflective of Latin America's primary continental ancestries-African (AFR), Amerindigenous (AMR), and European (EUR).

20∗20∗60: A multilevel climate change analysis framework.

J Environ Manage

January 2025

Centro Studi PLINIVS, University of Naples Federico II, 80134, Naples, Italy; Department of Architecture, University of Naples Federico II, 80134, Naples, Italy. Electronic address:

Cities worldwide have established plans and policies to achieve climate-neutral and climate-resilient objectives in recent decades. Researches have demonstrated that Climate Change Action Plans generally fail to include mitigation and adaptation approaches in their planning processes, despite their importance. A proposed multilevel assessment of Climate Change Action Plans, urban regeneration, and building projects was used to analyze the ten cities most sustainable in terms of developing environmental strategies, including local climate action to determine the degree of adaptation and mitigation integration in cutting-edge contexts and to identify measures that show synergies and co-benefits for urban design practices.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Purpose: Continuous EEG (cEEG) monitoring is increasingly used in the management of neonates with seizures. There remains debate on what clinically relevant information can be gained from cEEG in neonates with suspected seizures, at high risk for seizures, or with definite seizures, as well as the use of cEEG for prognosis in a variety of conditions. In this guideline, we address these questions using American Clinical Neurophysiology Society structured methodology for clinical guideline development.

We study image segmentation using spatiotemporal dynamics in a recurrent neural network where the state of each unit is given by a complex number. We show that this network generates sophisticated spatiotemporal dynamics that can effectively divide an image into groups according to a scene's structural characteristics. We then demonstrate a simple algorithm for object segmentation that generalizes across inputs ranging from simple geometric objects in grayscale images to natural images.

Dry deposition is an important yet poorly constrained process that removes reactive organic carbon from the atmosphere, making it unavailable for airborne chemical reactions and transferring it to other environmental systems. Using an aircraft-based measurement method, we provide large-scale estimates of total gas-phase organic carbon deposition rates and fluxes. Observed deposition rates downwind of large-scale unconventional oil operations reached up to 100 tC hour, with fluxes exceeding 0.

Effective global action against antimicrobial resistance (AMR) relies on the successful synthesis and translation of rigorous scientific evidence into policy and practice. Despite a call in 2019 by the Interagency Coordination Group on AMR to establish a policy-science interface, and the reaffirmation to establish a scientific panel in the 2024 Political Declaration on Antimicrobial Resistance, no authoritative entity currently exists that synthesizes the scientific evidence on AMR and outlines policy options based on the best scientific insight. A Scientific Panel on Evidence for Action against AMR (SPEA) could address this gap, as well as contribute to additional governance gaps in the space of AMR, by facilitating better global coordination and cooperation; establishing real-time evidence to guide policy actions; and monitoring progress towards any globally agreed upon AMR goals and targets.

Benzene degradation under anoxic conditions was first reported more than 25 years ago; however, the activation mechanism in the absence of oxygen remains elusive. Progress has been hindered by the difficulty in cultivating anaerobic benzene-degrading enrichment cultures. Our laboratory has sustained a methanogenic enrichment culture harboring ORM2, a benzene fermenter distinct from any known genus but related to other known or predicted benzene degraders.
