Direct Observation of Fully Spin-Polarized Tunnel Current Between Quantum Spins Using a Single Molecule Sensor.

Controlling spin-polarized currents at the nanoscale is of immense importance for high-density magnetic data storage and spin-based logic devices. As electronic devices are miniaturized to the ultimate limit of individual atoms and molecules, electronic transport is strongly influenced by the properties of the individual spin centers and their magnetic interactions. In this work, we demonstrate the precise control and detection of spin-polarized currents through two coupled spin centers at a tunnel junction by controlling their spin-spin interactions.

Direct Electrical Access to the Spin Manifolds of Individual Lanthanide Atoms.

Lanthanide atoms show long magnetic lifetimes because of their strongly localized 4 electrons, but electrical control of their spins has been difficult because of their closed valence shell configurations. We achieved electron spin resonance of individual lanthanide atoms using a scanning tunneling microscope to probe the atoms bound to a protective insulating film. The atoms on this surface formed a singly charged cation state having an unpaired 6 electron, enabling tunnel current to access their 4 electrons.

Isatuximab, Lenalidomide, Bortezomib, and Dexamethasone Induction Therapy for Transplant-Eligible Newly Diagnosed Multiple Myeloma: Final Part 1 Analysis of the GMMG-HD7 Trial.

Previously, addition of isatuximab (Isa) to standard-of-care lenalidomide-bortezomib-dexamethasone (RVd) in transplant-eligible patients with newly diagnosed multiple myeloma in the GMMG-HD7 trial (ClinicalTrials.gov identifier: NCT03617731) resulted in a significant increase of minimal residual disease negativity (MRD-) rates after induction therapy. A total of 662 patients were randomly assigned to receive induction therapy with Isa-RVd (n = 331) or RVd (n = 329), followed by single or tandem autologous stem-cell transplant and second random assignment to maintenance with lenalidomide alone or Isa-lenalidomide.

The Validation of Digital PCR-Based Minimal Residual Disease Detection for the Common Mutations in IDH1 and IDH2 Genes in Patients with Acute Myeloid Leukemia.

Accurate monitoring of minimal residual disease (MRD) is crucial for effective management of patients with acute myeloid leukemia (AML). This study aims to validate MRD detection of the seven most common IDH1 and IDH2 mutations in patients with AML using a QuantStudio 3D digital PCR platform. This assay demonstrated a high concordance for the variant allele frequencies between digital PCR and next-generation sequencing assays.

Emerging roles of cohesin-STAG2 in cancer.

Cohesin, a crucial regulator of genome organisation, plays a fundamental role in maintaining chromatin architecture as well as gene expression. Among its subunits, STAG2 stands out because of its frequent deleterious mutations in various cancer types, such as bladder cancer and melanoma. Loss of STAG2 function leads to significant alterations in chromatin structure, disrupts transcriptional regulation, and impairs DNA repair pathways.

The complex landscape of luminal breast cancer.

The breast epithelium, vital for mammary gland function, is influenced by oestrogen through the oestrogen receptor (ER) signalling pathway. Luminal breast cancer (BC), characterised by ER expression, comprises the majority of all BCs and presents significant clinical challenges due to therapy resistance and recurrence. Despite advancements in understanding luminal disease, improving long-term survival and reducing relapse of BC patients by predicting therapy efficacy and understanding resistance mechanisms remain critical challenges.

Clinico-pathological specificities of gingival carcinoma among 32 patients with oral cancer: a cross sectional retrospective and observational study.

Background: The study aimed to examine the prevalence of gingival cancers compared to other oral mucosal sites, analyze patient profiles, and identify risk factors.

Materials And Methods: A retrospective monocentric study was conducted at the Department of Oral Medicine of Bretonneau Hospital in Paris, France. 32 patients diagnosed with oral mucosal cancer were included.

Right Information, Right Care, Right Patient, Right Time: Community Preferences to Inform a Self-Management Support Tool for Upper Respiratory Symptoms.

Introduction: During and after the COVID-19 pandemic, communities must cope with several conditions that cause similar upper-respiratory symptoms but are managed differently. We describe community reactions to a self-management toolkit for patients with upper respiratory symptoms to inform mobile e-health app development. The toolkit is based on the '4R' (Right Information, Right Care, Right Patient, Right Time) care planning and management model.

Bone marrow transplantation increases sulfatase activity in somatic tissues in a multiple sulfatase deficiency mouse model.

Background: Multiple Sulfatase Deficiency (MSD) is an ultra-rare autosomal recessive disorder characterized by deficient enzymatic activity of all known sulfatases. MSD patients frequently carry two loss of function mutations in the SUMF1 gene, encoding a formylglycine-generating enzyme (FGE) that activates 17 different sulfatases. MSD patients show common features of other lysosomal diseases like mucopolysaccharidosis and metachromatic leukodystrophy, including neurologic impairments, developmental delay, and visceromegaly.

Characterization of Collaborative Cross mouse founder strain CAST/EiJ as a novel model for lethal COVID-19.

Mutations in SARS-CoV-2 variants of concern (VOCs) have expanded the viral host range beyond primates, and a few other mammals, to mice, affording the opportunity to exploit genetically diverse mouse panels to model the broad spectrum of responses to infection in patient populations. Here we surveyed responses to VOC infection in genetically diverse Collaborative Cross (CC) founder strains. Infection of wild-derived CC founder strains produced a broad range of viral burden, disease susceptibility and survival, whereas most other strains were resistant to disease despite measurable lung viral titers.

Impaired axon initial segment structure and function in a model of developmental and epileptic encephalopathy.

Developmental and epileptic encephalopathies (DEE) are rare but devastating and largely intractable childhood epilepsies. Genetic variants in , encoding a scaffolding protein important for the organization of the postsynaptic density of inhibitory synapses, are associated with DEE accompanied by complex neurological phenotypes. In a mouse model carrying a patient-derived variant associated with severe disease, we observed aggregation of postsynaptic proteins and loss of functional inhibitory synapses at the axon initial segment (AIS), altered axo-axonic synaptic inhibition, disrupted action potential generation, and complex seizure phenotypes consistent with clinical observations.

A Comprehensive Atlas of AAV Tropism in the Mouse.

Gene therapy with Adeno-Associated Viral (AAV) vectors requires knowledge of their tropism within the body. Here we analyze the tropism of ten naturally occurring AAV serotypes (AAV3B, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAVrh8, AAVrh10 and AAVrh74) following systemic delivery into male and female mice. A transgene expressing ZsGreen and Cre recombinase was used to identify transduction in a cell-dependent manner based on fluorescence.

Now in its 25th year, the Mutant Mouse Resource and Research Center (MMRRC) consortium continues to serve the United States and international biomedical scientific community as a public repository and distribution archive of laboratory mouse models of human disease for research. Supported by the National Institutes of Health (NIH), the MMRRC consists of 4 regionally distributed and dedicated vivaria, offices, and specialized laboratory facilities and an Informatics Coordination and Service Center (ICSC). The overarching purpose of the MMRRC is to facilitate groundbreaking biomedical research by offering an extensive repertoire of mutant mice that are essential for advancing the understanding of human physiology and disease.

Mechanisms that clear mutations drive field cancerization in mammary tissue.

Oncogenic mutations are abundant in the tissues of healthy individuals, but rarely form tumours. Yet, the underlying protection mechanisms are largely unknown. To resolve these mechanisms in mouse mammary tissue, we use lineage tracing to map the fate of wild-type and Brca1;Trp53 cells, and find that both follow a similar pattern of loss and spread within ducts.

Updated National and State-Specific Prevalence of Congenital Cytomegalovirus Infection, United States, 2018-2022.

Context: Congenital cytomegalovirus (cCMV) infection is the most common infectious cause of birth defects and the leading non-genetic cause of sensorineural hearing loss in the United States. Prior national cCMV infection prevalence estimates were based on one multi-site screening study conducted between 2007 and 2012 and were not adjusted for sociodemographic characteristics, such as maternal race and ethnicity or age.

Objective: This study sought to estimate national and state-specific prevalence of cCMV infection in the United States, adjusted for maternal race and ethnicity and maternal age group, by pooling estimates from published studies.
