A humanized antibody against mucormycosis targets angioinvasion and augments the host immune response.

Mucormycosis is a fungal infection caused by Mucorales fungi that cause severe disease and fatality, especially in immunocompromised individuals. Although vaccines and immunotherapeutics have been successful in combating viral and bacterial infections, approved antifungal immunotherapies are yet to be realized. To address this gap, monoclonal antibodies targeting invasive fungal infections have emerged as a promising approach, particularly for immunocompromised patients who are unlikely to maximally benefit from vaccines.

The pentameric complex is not required for congenital CMV transmission in seronegative rhesus macaques.

Congenital cytomegalovirus (cCMV) is the leading infectious cause of neonatal neurological impairment worldwide, but the viral factors enabling vertical spread across the placenta remain undetermined. The pentameric complex (PC), composed of the subunits gH/gL/UL128/UL130/UL131A, has been demonstrated to be important for entry into nonfibroblast cells in vitro. These findings link the PC to broad cell tropism and virus dissemination in vivo, denoting all subunits as potential targets for intervention strategies and vaccine development.

A human histidyl-tRNA synthetase splice variant therapeutic targets NRP2 to resolve lung inflammation and fibrosis.

Interstitial lung disease (ILD) consists of a group of immune-mediated disorders that can cause inflammation and progressive fibrosis of the lungs, representing an area of unmet medical need given the lack of disease-modifying therapies and toxicities associated with current treatment options. Tissue-specific splice variants (SVs) of human aminoacyl-tRNA synthetases (aaRSs) are catalytic nulls thought to confer regulatory functions. One example from human histidyl-tRNA synthetase (HARS), termed HARS because the splicing event resulted in a protein encompassing the WHEP-TRS domain of HARS (a structurally conserved domain found in multiple aaRSs), is enriched in human lung and up-regulated by inflammatory cytokines in lung and immune cells.

Spatial 3D genome organization reveals intratumor heterogeneity in primary glioblastoma samples.

Glioblastoma (GBM) is the most prevalent malignant brain tumor with poor prognosis. Although chromatin intratumoral heterogeneity is a characteristic feature of GBM, most current studies are conducted at a single tumor site. To investigate the GBM-specific 3D genome organization and its heterogeneity, we conducted Hi-C experiments in 21 GBM samples from nine patients, along with three normal brain samples.

A flexible pressure sensor array for self-powered identity authentication during typing.

The keyboard, a staple tool for information entry and human-machine interaction, faces demands for enhanced information security due to evolving internet technologies. This study introduces a self-powered flexible intelligent keyboard (SFIK) that harnesses the giant magnetoelastic effect to convert the mechanical pressure from key presses into electrical signals. The sensor boasts a wide sensing range (35 to 600 kPa) and a rapid response time (∼300 ms), allowing it to record and recognize individual keystroke dynamics.

Phagocytosis-driven neurodegeneration through opposing roles of an ABC transporter in neurons and phagocytes.

Lipid homeostasis is critical to neuronal survival. ATP-binding cassette A (ABCA) proteins are lipid transporters associated with neurodegenerative diseases. How ABCA transporters regulate lipid homeostasis in neurodegeneration is an outstanding question.

Y chromosome-linked UTY modulates sex differences in valvular fibroblast methylation in response to nanoscale extracellular matrix cues.

Aortic valve stenosis (AVS) is a progressive disease, wherein males more often develop valve calcification relative to females that develop valve fibrosis. Valvular interstitial cells (VICs) aberrantly activate to myofibroblasts during AVS, driving the fibrotic valve phenotype in females. Myofibroblasts further differentiate into osteoblast-like cells and produce calcium nanoparticles, driving valve calcification in males.

Active restoration of a long-lived octocoral drives rapid functional recovery in a temperate reef.

Whether restoration actions achieve full ecological recovery is still debated. This is particularly controversial in the marine realm, where the success of restoration is mostly evaluated in terms of the short-term survival of transplanted organisms. In view of this, we combined population and trait-based approaches to explore the long-term effectiveness of active restoration of a key Mediterranean octocoral.

Confronting Earth System Model trends with observations.

Anthropogenically forced climate change signals are emerging from the noise of internal variability in observations, and the impacts on society are growing. For decades, Climate or Earth System Models have been predicting how these climate change signals will unfold. While challenges remain, given the growing forced trends and the lengthening observational record, the climate science community is now in a position to confront the signals, as represented by historical trends, in models with observations.

Lipoylation inhibition enhances radiation control of lung cancer by suppressing homologous recombination DNA damage repair.

Lung cancer exhibits altered metabolism, influencing its response to radiation. To investigate the metabolic regulation of radiation response, we conducted a comprehensive, metabolic-wide CRISPR-Cas9 loss-of-function screen using radiation as selection pressure in human non-small cell lung cancer. Lipoylation emerged as a key metabolic target for radiosensitization, with lipoyltransferase 1 (LIPT1) identified as a top hit.

Shear flow patterns antimicrobial gradients across bacterial populations.

Bacterial populations experience chemical gradients in nature. However, most experimental systems either ignore gradients or fail to capture gradients in mechanically relevant contexts. Here, we use microfluidic experiments and biophysical simulations to explore how host-relevant shear flow affects antimicrobial gradients across communities of the highly resistant pathogen .

Counterions influence the isothermal self-assembly of DNA nanostructures.

DNA nanostructures are typically assembled by thermal annealing in buffers containing magnesium. We demonstrate the assembly of DNA nanostructures at constant temperatures ranging from 4° to 50°C in solutions containing different counterions. The choice of counterions and the assembly temperature influence the isothermal assembly of several DNA motifs and designed three-dimensional DNA crystals.

FlyVISTA, an integrated machine learning platform for deep phenotyping of sleep in .

There is great interest in using genetically tractable organisms such as to gain insights into the regulation and function of sleep. However, sleep phenotyping in has largely relied on simple measures of locomotor inactivity. Here, we present FlyVISTA, a machine learning platform to perform deep phenotyping of sleep in flies.

On-demand heralded MIR single-photon source using a cascaded quantum system.

We propose a mechanism for generating single photons in the mid-infrared (MIR) using a solid-state or molecular quantum emitter. The scheme uses cavity quantum electrodynamics (QED) effects to selectively enhance a Frank-Condon transition, deterministically preparing a single Fock state of a polar phonon mode. By coupling the phonon mode to an antenna, the resulting excitation is then radiated to the far field as a single photon with a frequency matching the phonon mode.

Synaptic-dependent developmental dysconnectivity in 22q11.2 deletion syndrome.

Chromosome 22q11.2 deletion increases the risk of neuropsychiatric disorders like autism and schizophrenia. Disruption of large-scale functional connectivity in 22q11 deletion syndrome (22q11DS) has been widely reported, but the biological factors driving these changes remain unclear.

Refugium amidst ruins: Unearthing the lost flora that escaped the end-Permian mass extinction.

Searching for land refugia becomes imperative for human survival during the hypothetical sixth mass extinction. Studying past comparable crises can offer insights, but there is no fossil evidence of diverse megafloral ecosystems surviving the largest Phanerozoic biodiversity crisis. Here, we investigated palynomorphs, plant, and tetrapod fossils from the Permian-Triassic South Taodonggou Section in Xinjiang, China.

Targeting the NPY/NPY1R signaling axis in mutant p53-dependent pancreatic cancer impairs metastasis.

Pancreatic cancer (PC) is a highly metastatic malignancy. More than 80% of patients with PC present with advanced-stage disease, preventing potentially curative surgery. The neuropeptide Y (NPY) system, best known for its role in controlling energy homeostasis, has also been shown to promote tumorigenesis in a range of cancer types, but its role in PC has yet to be explored.

Structure of coxsackievirus cloverleaf RNA and 3C dimer establishes the RNA-binding mechanism of enterovirus protease 3C.

In positive-strand RNA viruses, the genome serves as a template for both protein translation and negative-strand RNA synthesis. Enteroviruses use the cloverleaf RNA structure at the 5' end of the genome to balance these two processes. Cloverleaf acts as a promoter for RNA synthesis and forms a complex with viral 3CD protein, the precursor to 3C protease, and 3D polymerase.

Enhanced packaging of U6 small nuclear RNA and splicing-related proteins into extracellular vesicles during HIV infection.

U6 small nuclear RNA (U6 snRNA), a critical spliceosome component primarily found in the nucleus, plays a vital role in RNA splicing. Our previous study, using the simian immunodeficiency virus (SIV) macaque model, revealed an increase of U6 snRNA in plasma extracellular vesicles (EVs) in acute retroviral infection. Given the limited understanding of U6 snRNA dynamics across cells and EVs, particularly in SIV infection, this research explores U6 snRNA trafficking and its association with splicing proteins in the nucleus, cytoplasm, and EVs.

Privacy violations in election results.

After an election, should election officials release a copy of each anonymous ballot? Some policy-makers have championed public disclosure to counter distrust, but others worry that it might undermine ballot secrecy. We introduce the term vote revelation to refer to the linkage of a vote on an anonymous ballot to the voter's name in the public voter file and detail how such revelation could theoretically occur. Using the 2020 election in Maricopa County, Arizona, as a case study, we show that the release of individual ballot records would lead to no revelation of any vote choice for 99.

Collaborative role of two distinct cilium-specific cytoskeletal systems in driving Hedgehog-responsive transcription factor trafficking.

In vertebrate Hedgehog (Hh) signaling, the precise output of the final effectors, GLI (glioma-associated oncogene) transcription factors, depends on the primary cilium. Upon pathway initiation, generating the precise levels of the activator form of GLI depends on its concentration at the cilium tip. The mechanisms underlying this critical step in Hh signaling are unclear.

Public Insurance and Language Preferences Are Associated With a Longer Time to Surgery for Distal Radius Fractures.

Introduction: Insurance type can result in disparities in access to specialist orthopaedic care. Here, we sought to quantify how insurance type affects time to surgery in patients with a distal radius fracture that needs surgical treatment.

Methods: A retrospective cohort study of patients ≥18 years with surgically managed, closed distal radius fractures was conducted.

Nanoparticle-Based Pulmonary Immune Engineering.

Respiratory conditions represent a significant global healthcare burden impacting hundreds of millions worldwide and necessitating new treatment paradigms. Pulmonary immune engineering using synthetic nanoparticle (NP) platforms can reprogram immune responses for therapeutically beneficial or protective responses directly within the lung tissue. However, effectively localizing these game-changing approaches to the lung remains a significant challenge due to the lung's natural defense.

Intermediate-Term Oncologic Outcomes of Partial Nephrectomy Versus Cryoablation in Renal Tumors >3 cm: A Propensity Score Matched Analysis.

Purpose: Cryoablation (CA) and partial nephrectomy (PN) are effective nephron-sparing treatments for small renal masses. While guidelines list thermal ablation as an option for tumors <3 cm, limited data compare PN and CA in larger tumors. We compared intermediate-term oncologic outcomes between PN and CA in renal masses >3 cm.
