1q gain/amplification (1q+) is the most common cytogenetic abnormality (CA), with a frequency of 30-50% in patients with newly diagnosed multiple myeloma (NDMM). Although accumulating evidence supports 1q+ as a "high-risk" CA (HRCA), several issues remain to be addressed to understand its true prognostic property. We retrospectively analyzed a cohort of 934 patients with NDMM from three centers in China, who had baseline data available for 1q+ [including 1q21 gain (3 copies) and amplification (> 3 copies)] detected by fluorescence in situ hybridization in isolated CD138 cells, and who received first-line treatment with novel agents including proteasome inhibitors, immunomodulatory drugs, or both.

Existing research on federated learning (FL) usually assumes that training labels are of high quality for each client, which is impractical in many real-world scenarios (e.g., noisy labels by crowd-sourced annotations), leading to dramatic performance degradation.

For single-view clothed human reconstruction, the fashionable PIFu-like framework depends on the pixel-aligned feature essentially, while this leads to depth ambiguity and inaccuracy of representation. Additionally, this task faces the inherent problem of the lack of invisible information. To solve these two problems, we propose depth-guided pixel-aligned feature and multi-view consistency prior to constrain representation learning of the single-view reconstruction task.

M6A modification is one of the most common regulatory mechanisms of gene expression in eukaryotic cells, influencing processes such as RNA splicing, degradation, stability, and protein translation. Studies have shown that m6A methylation is closely associated with tumorigenesis and progression, and it plays a key regulatory role in tumor immune responses. m6A modification participates in regulating the differentiation and maturation of immune cells, as well as related anti-tumor immune responses.

Diabetic peripheral neuropathy (DPN) is a common diabetic complication with no currently available curative treatments. Here, we demonstrated that the protein level of G-protein-coupled receptor 40 (GPR40) is significantly repressed in the sciatic nerves (SN) of DPN patients, as well as in the peripheral nerves, including dorsal root ganglia (DRG) and SN, of streptozotocin (STZ)-induced type 1 diabetic mice and BKS Cg-m+/+Lepr db/J (db/db) type 2 diabetic mice. We identified that amlodipine besylate (AB), a first-line clinical antihypertensive drug, as a GPR40 agonist capable of alleviating DPN-like pathologies in mice.

Background: Maternal-derived antibody (MDA) interferes with immune responses, leading to the failure of H9N2 avian influenza vaccinations in poultry. So far, none of the commercially available H9N2 avian influenza vaccines used in poultry have been able to overcome MDA interference.

Methods: To develop a vaccine that can overcome MDA interference, one or multiple copies of the minimum-binding domain (P29) from the complement protein C3d were inserted in between the signal peptide and the head domain of the hemagglutinin (HA) protein on a H9N2 avian influenza virus (A/Chicken/Shanghai/H514/2017, named H514).

Introduction: Complex respiratory models, including air-liquid interface (ALI) transwell cultures and airway organoids, have emerged as promising tools for studying human respiratory virus infections. These models address several limitations of conventional two-dimensional cell line and animal models. However, the lack of standardized protocols for the application of these models in infection studies limits the possibilities for comparing results across different research groups.

Objective: Thrombotic events (TEs) are common and severe complications of newly diagnosed multiple myeloma (NDMM). However, the impact of thrombosis on the survival of myeloma patients remains controversial. The aim of our study was to identify independent high-risk factors for thrombosis as well as to explore the association between the incidence of TEs and survival in patients with NDMM.

Renal impairment (RI) is a common complication of multiple myeloma (MM), which is associated with poor prognosis. Here, we revealed the association between regular examination data and RI incidence, RI response and survival in newly diagnosed multiple myeloma (NDMM) patients.

The aryl hydrocarbon receptor (AHR) possesses an extraordinary capacity to sense and respond to a wide range of small-molecule ligands, ranging from polycyclic aromatic hydrocarbons to endogenous compounds. Upon ligand binding, AHR translocates from the cytoplasm to nucleus, forming a transcriptionally active complex with aryl hydrocarbon receptor nuclear translocator (ARNT), for DNA binding and initiation of gene expression programs that include cellular detoxification pathways and immune responses. Here, we examine the molecular mechanisms governing AHR's high-affinity binding and activation by a diverse group of ligands.

Here, we present Link-Seq, a highly efficient droplet microfluidic method for combined sequencing of antibody-encoding genes and the transcriptome of individual B cells at large scale. The method is based on 3' barcoding of the transcriptome and subsequent single-molecule PCR in droplets, which freely shift the barcode along specific gene regions, such as the antibody heavy- and light-chain genes. Using the immune repertoire of COVID-19 patients and healthy donors as a model system, we obtain up to 91.

Multi-label zero-shot learning (ML-ZSL) strives to recognize all objects in an image, regardless of whether they are present in the training data. Recent methods incorporate an attention mechanism to locate labels in the image and generate class-specific semantic information. However, the attention mechanism built on visual features treats label embeddings equally in the prediction score, leading to severe semantic ambiguity.

Gastric ulcer (GU), a common digestive system disorder in clinical practice, often arises from excessive alcohol consumption and other factors that irritate the gastric mucosa. Effective treatment of GU remains challenging due to the poor targeting, limited efficacy, and significant side effects associated with current therapeutic approaches. To address these limitations, we developed a microenvironment-responsive hydrogel composed of sodium alginate (SA) and chitosan (CS), incorporating MnO nanoparticles and pachymic acid (PA).

The rapid and selective identification of microorganisms is of great significance for clinical therapy applications. To develop high performance probes for microbe determination, we systemically constructed series aggregation-induced emission (AIE) luminogens by modulating the structural planarity, the basicity of functional group, the length of linker moiety and the hydrophobicity based on our previous work. The detail structure-property relationship study based on experimental and theoretical observation revealed that: i) the planar skeleton is essential for probe insertion towards the cell wall via van n der Waals' force.

Objectives: Formyl peptide receptor 1 (FPR1) is a member of G protein-coupled receptor (GPCR) family that detects potentially danger signals characterized by the appearance of N-formylated peptides which originate from either bacteria or host mitochondria during organ injury, including sepsis. Mitochondrial-encoded NADH dehydrogenase 6 (MT-ND6) and Annexin A1 (ANXA1), as mitochondrial damage-associated molecular patterns (mtDAMPs) agonist and endogenous agonist of FPR1 respectively, interact with FPR1 regulating polymorphonuclear leukocytes (PMNs) function and inflammatory response during sepsis. However, there is no direct evidence of MT-ND6 or ANXA1 in the circulation of patients with sepsis and their potential role in clinical significance, including diagnosis and mortality prediction during sepsis.
