The Characteristics of Peripheral Blood Lymphocyte Subsets in HIV-related Diffuse Large B-cell Lymphoma Patients and Their Impact on Treatment Efficacy.

Introduction: Peripheral blood lymphocyte subsets have been shown to influence prognosis in HIV-associated Diffuse Large B-Cell Lymphoma (HIV-DLBCL), a rare and highly aggressive form of non-Hodgkin's lymphoma linked to immunosuppression and abnormal B-cell proliferation. To lay the foundation for individualized therapy based on factors such as CD4+/CD8+ ratio and Treg/NK cell characteristics, this retrospective study was conducted to explore the variations in lymphocyte subset levels.

Methods: Overall, 51 HIV-DLBCL patients, 50 DLBCL patients, and 42 Healthy Donors (HD) were enrolled in the study.

Nutritional and immune-inflammatory scoring system for predicting outcomes in newly diagnosed diffuse large B-cell lymphoma patients.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common aggressive non-Hodgkin lymphoma and often carries a poor prognosis. Current prognostic systems such as the International Prognostic Index (IPI) and National Comprehensive Cancer Network (NCCN)-IPI do not incorporate patients' nutritional, immune, or inflammatory status, which may affect outcomes.

Methods: We retrospectively analyzed 423 newly diagnosed DLBCL patients and collected 12 clinical indicators reflecting nutritional, immune, and inflammatory status.

Transposable elements as novel therapeutic targets for PARPi-induced synthetic lethality in PcG-mutated blood cancer.

Loss-of-function (LoF) mutations frequently found in human cancers are generally intractable by classical small molecule inhibitor approaches. Among them are mutations affecting polycomb-group (PcG) epigenetic regulators, EZH2 and ASXL1 frequently found in haematological malignancies of myeloid or lymphoid lineage, and their concurrent mutations associates with particularly poor prognosis. While there is clear need to develop novel and effective treatments for these patients, the lack of appropriate disease models and mechanistic insights have significantly hindered the progresses.

Salt-Assisted Fabrication of a Water-Based Covalent Organic Framework Ink and Its Hybrid Films for Photothermal Actuators.

The exceptional properties of two-dimensional covalent organic framework materials (2D-COFs), including their large π-conjugated structure at the molecular level and π-π multilayer stacking, have attracted interest for soft photothermal actuator applications. However, the conventional synthesis of COFs as microcrystalline powders limits their processing in water due to their limited dispersibility. Herein, we present a simple and environmentally friendly method to fabricate water-suspended COF inks by adjusting the surface potential of COF powders through adsorption of ionic species such as Na and Cl.

Ultrathin Covalent Organic Framework Nanosheets/TiCT-Based Photoelectrochemical Biosensor for Efficient Detection of Prostate-Specific Antigen.

Designable and ultrathin covalent organic framework nanosheets (CONs) with good photoelectric activity are promising candidates for the construction of photoelectrochemical (PEC) biosensors for the detection of low-abundance biological substrates. However, achieving highly sensitive PEC properties by using emerging covalent organic framework nanosheets (CONs) remains a great challenge due to the polymeric nature and poor photoelectric activity of CONs. Herein, we report for the first time the preparation of novel composites and their PEC sensing properties by electrostatic self-assembly of ultrathin CONs (called TTPA-CONs) with TiCT.

Ultrathin MOF nanosheet-based resistive sensors for highly sensitive detection of methanol.

Sensors with high-sensitivity for resistive methanol gas detection are highly desirable. Herein, we report newly designed ultrathin anionic metal-organic framework (MOF) nanosheets (NSs), with an average thickness of 10 nm and an electrical conductivity of 3.77 × 10 S cm.

Micro- and Macro-Anatomical Frameworks of Lymph Nodes Indispensable for the Lymphatic System Filtering Function.

In the lymphatic vascular system, lymph nodes (LNs) play a pivotal role in filtering and removing lymph-borne substances. The filtering function of LNs involves resident macrophages tightly associated with unique lymphatic sinus structures. Moreover, an intermittently arranged LN in the lymphatic pathway is considered to cooperatively prevent lymph-borne substances from entering blood circulation.

Synthesis and Visualization of Entangled 3D Covalent Organic Frameworks with High-Valency Stereoscopic Molecular Nodes for Gas Separation.

The structural diversity of three-dimensional (3D) covalent organic frameworks (COFs) are limited as there are only a few choices of building units with multiple symmetrically distributed connection sites. To date, 4 and 6-connected stereoscopic nodes with T , D , D and C symmetries have been mostly reported, delivering limited 3D topologies. We propose an efficient approach to expand the 3D COF repertoire by introducing a high-valency quadrangular prism (D ) stereoscopic node with a connectivity of eight, based on which two isoreticular 3D imine-linked COFs can be created.

Landscape of Prognostic m6A RNA Methylation Regulators in Hepatocellular Carcinoma to Aid Immunotherapy.

Hepatocellular carcinoma (HCC) is the sixth most common malignancy with a high mortality worldwide. N6-methyladenosine (m6A) may participate extensively in tumor progression. To reveal the landscape of tumor immune microenvironment (TIME), ESTIMATE analysis, ssGSEA algorithm, and the CIBERSORT method were used.

Multi-omics analysis reveals prognostic value of tumor mutation burden in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) was the sixth common malignancies characteristic with highly aggressive in the world. It was well established that tumor mutation burden (TMB) act as indicator of immunotherapeutic responsiveness in various tumors. However, the role of TMB in tumor immune microenvironment (TIME) is still obscure.

Immunological significance of prognostic alternative splicing signature in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) ranks the sixth prevalent tumors with high mortality globally. Alternative splicing (AS) drives protein diversity, the imbalance of which might act an important factor in tumorigenesis. This study aimed to construct of AS-based prognostic signature and elucidate the role in tumor immune microenvironment (TIME) and immunotherapy in HCC.
