dFCExpert: Learning Dynamic Functional Connectivity Patterns with Modularity and State Experts.

Characterizing brain dynamic functional connectivity (dFC) patterns from functional Magnetic Resonance Imaging (fMRI) data is of paramount importance in neuroscience and medicine. Recently, many graph neural network (GNN) models, combined with transformers or recurrent neural networks (RNNs), have shown great potential for modeling the dFC patterns. However, these methods face challenges in effectively characterizing the modularity organization of brain networks and capturing varying dFC state patterns.

Anticorrosion coating with near-infrared light triggered precisely controllable self-healing performances.

Great attentions have been paid to anticorrosion coatings with self-healing performances to enhance its reliability and protection period, but massive challenges still remain for developing a coating with selectively triggered and accurately controllable self-healing behaviors. Herein, by integrating lamellar graphene oxide (GO) into a polycaprolactone (PCL) nanofiber loaded with 8-hydroxyquinoline (8HQ) corrosion inhibitors, a composite coating with precisely controllable self-healing capabilities is developed. The coating defects can be remotely and accurately repaired under near-infrared (NIR) light irradiation within a very short time.

NRP1 instructs IL-17-producing ILC3s to drive colitis progression.

Group 3 innate lymphoid cells (ILC3s) control tissue homeostasis and orchestrate mucosal inflammation; however, the precise mechanisms governing ILC3 activity are fully understood. Here, we identified the transmembrane protein neuropilin-1 (NRP1) as a positive regulator of interleukin (IL)-17-producing ILC3s in the intestine. NRP1 was markedly upregulated in intestinal mucosal biopsies from patients with inflammatory bowel disease (IBD) compared with healthy controls.

Effect of freezing and thawing on ejaculated sperm and subsequent pregnancy and neonatal outcomes in IVF.

Background: Techniques for sperm cryopreservation have exhibited their potential in male fertility preservation. The use of frozen-thawed sperm in fertilization (IVF) cycles is widespread today. However, many studies reported that cryopreservation might have adverse effects on sperm DNA integrity, motility, and fertilization, probably due to cold shock, intra- and extracellular ice crystals, and excess reactive oxygen species (ROS).

SegCSR: Weakly-Supervised Cortical Surfaces Reconstruction from Brain Ribbon Segmentations.

Deep learning-based cortical surface reconstruction (CSR) methods heavily rely on pseudo ground truth (pGT) generated by conventional CSR pipelines as supervision, leading to dataset-specific challenges and lengthy training data preparation. We propose a new approach for reconstructing multiple cortical surfaces using from brain MRI ribbon segmentations. Our approach initializes a midthickness surface and then deforms it inward and outward to form the inner (white matter) and outer (pial) cortical surfaces, respectively, by jointly learning diffeomorphic flows to align the surfaces with the boundaries of the cortical ribbon segmentation maps.

The Therapeutic Potential of Pristimerin in Osteoarthritis: Mechanistic Insights from in vitro and in vivo Studies.

Objective: Osteoarthritis (OA), a degenerative disease marked by cartilage erosion and synovial proliferation, has led to an increased interest in natural plant-based compounds to slow its progression. Pristimerin(Pri), a triterpenoid compound derived from Tripterygium wilfordii, has demonstrated anti-inflammatory and antioxidant characteristics. This study explores the protective effects of Pri on OA and its potential mechanisms.

Osteoarthritis (OA) is a prevalent, degenerative joint disease that requires effective treatments to prevent its progression. Therefore, the development of novel therapeutic strategies to address this unmet clinical challenge is paramount. Marein (MA), the principal active compound of Coreopsis tinctoria Nutt, exhibits anti-inflammatory and anti-oxidant properties in various diseases, indicating its potential as a therapeutic agent for OA.

Brain-clinical pattern alterations after treatment in schizophrenia.

Discovering meaningful brain-clinical patterns would be a significant advancement for elucidating the pathophysiology underlying schizophrenia. In the present study, we analyzed associations between functional brain characters (average functional connectivity strength and its fluctuations) and clinical features (age onset, illness duration, and positive, negative, disorganized, excited, and depressed) using partial least squares. Also, we analyzed the brain-clinical relationship changes after 6-wk of treatment.

Examining the practical importance of nonstationary cardio-respiratory coupling detection in breathing training: a methodological appraisal.

This study investigates changes in cardiorespiratory coupling during clinic breathing training and its impact on autonomic nervous functioning compared with heart rate variability (HRV). A total of 39 subjects undergoing dynamic electrocardiogram-recorded breathing training were analyzed. Subjects were divided into early- and late-training periods, and further categorized based on changes in HRV indexes.

AMP-dependent protein kinase alpha 1 predicts cancer prognosis and immunotherapy response: from pan-cancer analysis to experimental validation.

Pancreatic cancer (PC) has poor prognosis. PRKAA1 (AMPK-α1) is the catalytic subunit of 5'-adenylate-activated protein kinase (AMPK), which plays a critical role in multiple stages of tumorigenesis and development. However, the biological mechanisms of PRKAA1 in the tumor microenvironment have not been well studied.

Littoral cell angioma of a huge spleen with peripheral blood pancytopenia in a 14-year-old boy: a case report and review of the literature.

Background: Splenic littoral cell angioma (LCA) is an exceptionally uncommon malignant potential vascular tumor with infrequent occurrences in pediatric patients. Due to its reliance on histopathological analysis for diagnosis, LCA may be mistakenly identified as other splenic tumors. Patients with LCA may experience anemia or thrombocytopenia, but peripheral blood pancytopenia is infrequent.

Engineering immune organoids to regenerate host immune system.

Recent advances in immunotherapy have underscored the potential of harnessing the immune system to treat disorders associated with immune dysregulation, such as primary and secondary immunodeficiencies, cancer, transplantation rejection, and aging. Owing to the cellular and structural complexity and the dynamic nature of immune responses, engineering immune organoids that replicate the function and key features of their corresponding immune organs continues to be a formidable challenge. In this overview, we will discuss the recent progress in bioengineering organoids of key primary and secondary immune organs and tissues, focusing particularly on their contributions to the host's immune system in animal models and highlighting their potential roles in regenerative medicine.

Relationship between MRI brain-age heterogeneity, cognition, genetics and Alzheimer's disease neuropathology.

Background: Brain ageing is highly heterogeneous, as it is driven by a variety of normal and neuropathological processes. These processes may differentially affect structural and functional brain ageing across individuals, with more pronounced ageing (older brain age) during midlife being indicative of later development of dementia. Here, we examined whether brain-ageing heterogeneity in unimpaired older adults related to neurodegeneration, different cognitive trajectories, genetic and amyloid-beta (Aβ) profiles, and to predicted progression to Alzheimer's disease (AD).
