Hepatovirus translation requires PDGFA-associated protein 1, an eIF4E-binding protein regulating endoplasmic reticulum stress responses.

The overexpression and misfolding of viral proteins in the endoplasmic reticulum (ER) may cause cellular stress, thereby inducing a cytoprotective, proteostatic host response involving phosphorylation of eukaryotic translation initiation factor 2 subunit alpha (eIF2α). Here, we show that hepatitis A virus, a positive-strand RNA virus responsible for infectious hepatitis, adopts a stress-resistant, eIF2α-independent mechanism of translation to ensure the synthesis of viral proteins within the infected liver. Cap-independent translation directed by the hepatovirus internal ribosome entry site and productive hepatovirus infection of mice both require platelet-derived growth factor subunit A (PDGFA)-associated protein 1 (PDAP1), a small phosphoprotein of unknown function with eIF4E-binding activity.

Homologation of Carboxylic Acids Using a Radical-Polar Conjunctive Reagent.

Homologations of organic molecules that add a carbon atom to the substrate are useful in drug discovery to access compounds with improved properties that otherwise present a synthetic challenge. Carboxylic acids are present in many bioactive molecules and are widely available building blocks for chemical synthesis, yet their direct homologation is unknown. This valuable transformation currently necessitates implementation of multistep processes that require the use of carboxylic acid derivatives rather than the native substrates, and commonly involves highly reactive and toxic reagents.

Evidence for dual roles of histone H3 lysine 4 in antagonizing Polycomb group function and promoting target gene expression.

Tight control over cell identity gene expression is necessary for proper adult form and function. The opposing activities of Polycomb and trithorax complexes determine the on/off state of cell identity genes such as the Hox factors. Polycomb group complexes repress target genes, whereas trithorax group complexes are required for their expression.

Influence of Matching the Processing Delays of Cochlear Implant and Hearing Aid Devices for Bimodal Listeners on Speech Recognition in Noise.

Purpose: Cochlear implant (CI) recipients who listen with a hearing aid (HA) in the contralateral ear, known as bimodal listeners, demonstrate individual variability in speech recognition in noise. This variability may be due in part to differences in the processing delays of the CI and HA devices. This study investigated the influence of matching the processing delays of CI and HA devices on masked speech recognition for bimodal listeners.

Effortful Control, Parent-Child Relationships, and Behavior Problems among Preschool-Aged Children Experiencing Adversity.

Young children who experience adversity are at increased risk for developing psychological difficulties across the lifespan. Among community samples, parent-child relationship dynamics interact with child effortful control to predict child behavior problems. The nature of these associations has not been examined among children who have experienced early childhood adversity and who may be particularly sensitive to familial effects on child development.

Leveraging Single-Cell RNA-Seq to Generate Robust Microglia Aging Clocks.

'Biological aging clocks' - composite molecular markers thought to capture an individual's biological age - have been traditionally developed through bulk-level analyses of mixed cells and tissues. However, recent evidence highlights the importance of gaining single-cell-level insights into the aging process. Microglia are key immune cells in the brain shown to adapt functionally in aging and disease.

Biological and prognostic relevance of epigenetic regulatory genes in high-grade gliomas.

Background: High-grade gliomas (HGGs) are the most aggressive type of gliomas and have the poorest outcomes. Chromatin remodeling (CR) genes have been implicated in multiple oncogenic pathways in numerous cancer types. In gliomagenesis, CR genes have been implicated in regulating the stemness of glioma cells, the tumor microenvironment (TME), and resistance to therapies.

Effect of an abdominal binder on postoperative outcomes after ventral hernia repair: a systematic review and meta-analysis of randomized controlled trials.

Introduction: Abdominal binders consist of a wide compression belt that encircles the abdomen, theoretically supporting the abdominal wall. However, their use after ventral hernia repair is debated. Therefore, this meta-analysis evaluates their efficacy.

Searching for Equity: Strategies for Enhancing Racial/Ethnic Diversity in Applicant Pools for Public Health Faculty Searches.

Low racial/ethnic diversity among public health academics undermines our research, teaching, and practice. One important step for addressing this problem is to increase the diversity of applicant pools for open faculty positions. In this commentary, we share our experience conducting a tenure-track faculty search at a large public university.

Development of a biocompatible 3D hydrogel scaffold using continuous liquid interface production for the delivery of cell therapies to treat recurrent glioblastoma.

Glioblastoma (GBM) is the most common primary malignant brain tumor diagnosed in adults, carrying with it an extremely poor prognosis and limited options for effective treatment. Various cell therapies have emerged as promising candidates for GBM treatment but fail in the clinic due to poor tumor trafficking, poor transplantation efficiency, and high systemic toxicity. In this study, we design, characterize, and test a 3D-printed cell delivery platform that can enhance the survival of therapeutic cells implanted in the GBM resection cavity.

Molecular Characterization and Photoreactivity of Organic Aerosols Formed from Pyrolysis of Urban Materials during Fires at the Wildland-Urban Interface.

Fires at the wildland-urban interface (WUI) are increasing in magnitude and frequency, emitting organic aerosol (OA) with unknown composition and atmospheric impacts. In this study, we investigated the chemical composition of OA produced through the 600 °C pyrolysis of ten urban materials in nitrogen, which were subsequently aged under UV light for 2 h. The analysis utilized ultrahigh-performance liquid chromatography (UHPLC) separation, coupled with a photodiode array (PDA) detector and a high-resolution mass spectrometer (HRMS) for molecular characterization.

Near-infrared spectroscopy-enabled electromechanical systems for fast mapping of biomechanics and subcutaneous diagnosis.

Fast and accurate assessment of skin mechanics holds great promise in diagnosing various epidermal diseases, yet substantial challenges remain in developing simple and wearable strategies for continuous monitoring. Here, we present a design concept, named active near-infrared spectroscopy patch (ANIRP) for continuously mapping skin mechanics. ANIRP addresses these challenges by integrating near-infrared (NIR) sensing with mechanical actuators, enabling rapid measurement (<1 s) of Young's modulus, high spatial sensing density (~1 cm), and high spatial sensitivity (<1 mm).
