Background And Purpose: The underlying transcriptomic signatures driving brain functional alterations in MS and neuromyelitis optica spectrum disorder (NMOSD) are still unclear.

Materials And Methods: Regional fractional amplitude of low-frequency fluctuation (fALFF) values were obtained and compared among 209 patients with MS, 90 patients with antiaquaporin-4 antibody (AQP4)+ NMOSD, 49 with AQP4- NMOSD, and 228 healthy controls from a discovery cohort. We used partial least squares (PLS) regression to identify the gene transcriptomic signatures associated with disease-related fALFF alterations.

Article Synopsis
  • Cardiac ischemia/reperfusion (I/R) injury is a significant concern for heart disease, but there's currently no effective treatment to minimize this type of heart damage.
  • This study recruited patients with acute myocardial infarction to examine the impact of plasma RIPK3 levels before and after treatment, using both patient data and lab experiments on cells and mouse models.
  • Elevated RIPK3 levels post-treatment were linked to worse outcomes, and experiments showed that RIPK3 worsens heart injury by triggering inflammation, suggesting its role as a damaging molecule that could be targeted for therapy.

Article Synopsis
  • The study aimed to identify predictors for relapse in patients with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and create a risk score to predict relapse.
  • Researchers followed 188 patients from the China National Registry of Neuro-Inflammatory Diseases (CNRID) and found key factors such as female sex and age at onset that influence relapse risk.
  • The developed MOG-AR score effectively predicts relapse risk, indicating that a score between 13-16 significantly correlates with a higher risk of relapse, suggesting the potential for better patient management and treatment strategies.

Background: Cardiac hypertrophy and its associated remodeling are among the leading causes of heart failure. Lysine crotonylation is a recently discovered posttranslational modification whose role in cardiac hypertrophy remains largely unknown. NAE1 (NEDD8 [neural precursor cell expressed developmentally downregulated protein 8]-activating enzyme E1 regulatory subunit) is mainly involved in the neddylation modification of protein targets.

Moiré superlattices formed by twisted stacking in van der Waals materials have emerged as a new platform for exploring the physics of strongly correlated materials and other emergent phenomena. However, there remains a lack of research on the mechanical properties of twisted-layer van der Waals materials, owing to a lack of suitable strategies for making three-dimensional bulk materials. Here we report the successful synthesis of a polycrystalline boron nitride bulk ceramic with high room-temperature deformability and strength.

Background And Objectives: The Ticagrelor or Clopidogrel with Aspirin in High-Risk Patients with Acute Nondisabling Cerebrovascular Events II (CHANCE-2) trial showed that among Chinese patients with minor ischemic stroke or transient ischemic attack (TIA) who were carriers of loss-of-function alleles, dual-antiplatelet therapy with ticagrelor-aspirin reduced the 90-day risk of stroke without increased severe or moderate bleeding compared with clopidogrel-aspirin. However, whether dual-antiplatelet therapy with ticagrelor was superior to clopidogrel beyond the 90 days of follow-up remained unclear. In this study, we reported 1-year follow-up outcomes of the CHANCE-2 trial.

Article Synopsis
  • Current atherosclerosis treatments struggle to reverse advanced plaque buildup, with high amino acid levels from a Western diet causing mTORC1-autophagy defects in macrophages, worsening the condition.* -
  • Research identified that the upregulation of Gpr137b-ps in atherosclerotic plaques impacts autophagy, with experiments on mice showing that reducing Gpr137b-ps enhances macrophage autophagy and reduces plaque lesions.* -
  • Gpr137b-ps seems to inhibit the binding of HSC70 to G3BP, which in turn affects mTORC1 signaling, suggesting targeting this pathway could offer a new avenue for treating advanced atherosclerosis.*

Background And Objective: Genotype data of the Clopidogrel with Aspirin in Acute Minor Stroke or Transient Ischemic Attack (CHANCE) trial showed that efficacy of clopidogrel aspirin depended on genotype and risk profile. A stratification of patients who carried loss-of-function (LOF) alleles according to the risk of recurrent stroke may be important for selecting optimal antiplatelet therapy. We aimed to compare the efficacy and safety of ticagrelor aspirin with clopidogrel aspirin in LOF carriers with minor stroke or transient ischemic attack (TIA) stratified by risk profile.
