Multi-omics analysis reveals the cerebral sex-specific responses to chronic hypoxia in yellow catfish (Pelteobagrus fulvidraco).

Hypoxia disrupts multiple physiological processes, including metabolism, immunity, and reproduction in teleosts. The brain plays a critical role in adapting to environmental changes, regulating the endocrine system, and controlling reproduction. The present study investigated the sex-specific cerebral responses to chronic hypoxia through an integrated analysis of the transcriptome, proteome, and metabolome of yellow catfish.

Females are Associated with Lower Risks of Long-Term Mortality in Patients Undergoing Off-Pump Coronary Artery Bypass Grafting.

Background: In patients who underwent off-pump coronary artery bypass grafting (OPCABG), females were reported to have lower rates of in-hospital mortality rate and postoperative atrial fibrillation than males. However, the association between gender and long-term prognosis following OPCABG is rarely reported.

Objective: This study aims to determine if women benefit more from OPCABG than men by comparing the difference in the risk of long-term all-cause mortality in patients with coronary chronic total occlusion (CTO).

Comparison of silent MRA and time-of-flight MRA in the depiction and grading of brain arteriovenous malformations.

Background: Preliminary small-sample studies suggest that silent magnetic resonance angiography (MRA) has an advantage over time-of-flight MRA (TOF MRA) in the characterization of brain arteriovenous malformation (BAVM), but did not examine whether the imaging performance of silent MRA was affected by the intrinsic features of BAVM or common clinical factors. This study sought to compare silent MRA and TOF MRA in terms of the visualization and grading of BAVMs in various clinical settings.

Methods: In total, 85 participants (50 males, 35 females; mean age: 33.

Intimal sarcoma of the aortic valve and ascending aorta: a case report.

Background: Intimal sarcomas are rare tumors that typically affect the major vessels, such as the pulmonary artery and aorta, and are associated with a particularly poor prognosis. Intimal sarcomas found in the aorta are most commonly located in the abdominal section between the celiac artery and the iliac bifurcation. The descending aorta is involved in 30% of cases, while involvement of the ascending aorta is rare.

Ultrasound-based radiomics to predict the volume reduction rate of benign thyroid nodules after microwave ablation.

Objective: To evaluate the predictive power of ultrasound-based radiomics models for benign thyroid nodules with a volume reduction rate (VRR) of < or ≥75% at 12 months after microwave ablation.

Methods: A retrospective study was conducted on 194 individuals with benign thyroid nodules who received ultrasound-guided microwave ablation between November 2019 and June 2023. The clinical and ultrasound features, including age, gender, volume, echogenicity, duration of ablation, and so on were analysed by t-test or chi-square test.

High-Affinity Peptides for Target Protein Screened in Ultralarge Virtual Libraries.

High-throughput virtual screening (HTVS) has emerged as a pivotal strategy for identifying high-affinity peptides targeting functional proteins, which are crucial for diagnostic and therapeutic applications. In the HTVS of peptides, expanding the library capacity to enhance peptide sequence diversity, thereby screening out excellent affinity peptide candidates, remains a significant challenge. This study presents a design strategy that leverages directed mutation driven HTVS to evolve vast virtual libraries and screen peptides with ultrahigh affinities for various target proteins.

Development of a predictive model for systemic lupus erythematosus incidence risk based on environmental exposure factors.

Objective: Systemic lupus erythematosus (SLE) is an autoimmune disease characterised by a loss of immune tolerance, affecting multiple organs and significantly impairing patients' health and quality of life. While hereditary elements are essential in the onset of SLE, external environmental influences are also significant. Currently, there are few predictive models for SLE that takes into account the impact of occupational and living environmental exposures.

Unlocking the potential of urban EV battery recycling: A dual optimization model.

As electric vehicles increase, they reduce greenhouse gas emissions but pose recycling challenges for their batteries. Economic and environmental impacts are significant concerns. This study proposes a dual optimization approach to develop a city-wide recycling network benefiting vehicle owners and recycling facilities.

Correlation between thyroid dysfunction and efficacy of immune checkpoint inhibitors in patients with advanced solid tumors.

Background: Immune checkpoint inhibitors (ICIs) are currently the first line of tumor immunotherapy for the treatment of a wide range of tumors. However, the main side effect of immune checkpoint inhibitors is that they cause immune-related adverse events (irAEs) in patients. The relationship between the occurrence of immune side effects in patients and efficacy is controversial.

FAMF-Net: Feature Alignment Mutual Attention Fusion with Region Awareness for Breast Cancer Diagnosis via Imbalanced Data.

Automatic and accurate classification of breast cancer in multimodal ultrasound images is crucial to improve patients' diagnosis and treatment effect and save medical resources. Methodologically, the fusion of multimodal ultrasound images often encounters challenges such as misalignment, limited utilization of complementary information, poor interpretability in feature fusion, and imbalances in sample categories. To solve these problems, we propose a feature alignment mutual attention fusion method (FAMF-Net), which consists of a region awareness alignment (RAA) block, a mutual attention fusion (MAF) block, and a reinforcement learning-based dynamic optimization strategy(RDO).

Development and applications of metabolic models in plant multi-omics research.

Plant growth and development are characterized by systematic and continuous processes, each involving intricate metabolic coordination mechanisms. Mathematical models are essential tools for investigating plant growth and development, metabolic regulation networks, and growth patterns across different stages. These models offer insights into secondary metabolism patterns in plants and the roles of metabolites.

Structure-guided design and photochemical synthesis of new carbamo(dithioperoxo)thioates with improved potencies to SARS-CoV-2 3CL.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has triggered a protracted global pandemic from 2019 to 2022, and posed a significant threat to human health. One of the non-structural proteins 3CL of SARS-CoV-2 is considered as a validated target for the development of inhibitors against the virus. Disulfiram has been reported as a covalent inhibitor of 3CL; however, its structure lacks bonding site with active pockets of 3CL and its highly symmetric structure doesn't match well with the irregular cavity of the active center, limiting its therapeutic applications.

An atlas of small non-coding RNAs in human preimplantation development.

Understanding the molecular circuitries that govern early embryogenesis is important, yet our knowledge of these in human preimplantation development remains limited. Small non-coding RNAs (sncRNAs) can regulate gene expression and thus impact blastocyst formation, however, the expression of specific biotypes and their dynamics during preimplantation development remains unknown. Here we identify the abundance of and kinetics of piRNA, rRNA, snoRNA, tRNA, and miRNA from embryonic day (E)3-7 and isolate specific miRNAs and snoRNAs of particular importance in blastocyst formation and pluripotency.
