Zygotic genome activation (ZGA) is crucial for maternal to zygotic transition at the 2-8-cell stage in order to overcome silencing of genes and enable transcription from the zygotic genome. In humans, ZGA is induced by DUX4, a pioneer factor that drives expression of downstream germline-specific genes and retroelements. Here we show that herpesviruses from all subfamilies, papillomaviruses and Merkel cell polyomavirus actively induce DUX4 expression to promote viral transcription and replication.

Background: The idea of making science more accessible to nonscientists has prompted health researchers to involve patients and the public more actively in their research. This sometimes involves writing a plain language summary (PLS), a short summary intended to make research findings accessible to nonspecialists. However, whether PLSs satisfy the basic requirements of accessible language is unclear.

Postoperative hemorrhages (POHs) after pituitary adenoma surgery can have devastating consequences for patients. Many patients take acetylsalicylic acid (ASA) for the primary or secondary prevention of cardiovascular or stroke events. However, the impact of continued low-dose ASA use on the risk of postoperative hemorrhage and the frequency of thromboembolic events after discontinuing ASA in these patients remain poorly understood.

Background: Within the dermatological community, topical steroid withdrawal syndrome (TSWS) is a medically contested condition with a limited research base. Published studies on TSWS indicate that it is a distinct adverse effect of prolonged use of topical corticosteroids, but there is a paucity of high-quality research evidence. Among the "patient community," awareness has been increasing, with rapid growth in social media posts on TSWS and the introduction of online communities such as the International Topical Steroid Awareness Network.

Background/objectives: Patients with gliomas show an increased risk of spontaneous hemorrhages throughout the disease. Simultaneously, the number of patients taking acetylsalicylic acid (ASA) for primary and secondary prophylaxis is rising in daily clinical practice, and interrupting ASA intake before elective or emergency intracranial surgery is not always feasible. This study aims to evaluate the risks associated with continuing ASA use perioperatively while focusing on hemorrhage and potential thromboembolic events that may arise from discontinuing ASA, particularly in multimorbid patients undergoing glioma surgery.

Background: Oral anticoagulation is recommended after ablation for atrial fibrillation among patients at high risk for stroke. Left atrial appendage closure is a mechanical alternative to anticoagulation, but data regarding its use after atrial fibrillation ablation are lacking.

Methods: We conducted an international randomized trial involving 1600 patients with atrial fibrillation who had an elevated score (≥2 in men and ≥3 in women) on the CHADS-VASc scale (range, 0 to 9, with higher scores indicating a greater risk of stroke) and who underwent catheter ablation.

Neurointensive care primarily focuses on secondary injury reduction, utilizing a variety of guideline-based approaches (including administration of high-dose sedation) to reduce the injured state. However, titration of sedation is currently based on the Richmond Agitation Sedation Scale (RASS), a subjective clinical grading score of a patient's response to external physical stimuli, and not an objective measure. Therefore, it is likely that there exists substantial variation in objective sedation depth for a given clinical grade in these patients, leading to undesired sedation depths and cerebral physiological consequences.

Nonuniform local translation speed dictates diverse protein biogenesis outcomes. To unify known and uncover unknown principles governing eukaryotic elongation rate, we developed a machine learning pipeline to analyze RiboSeq datasets. We find that the chemical nature of the incoming amino acid determines how codon optimality influences elongation rate, with hydrophobic residues more dependent on transfer RNA (tRNA) levels than charged residues.
