The association between chronotype and social anxiety among Chinese university students: a moderated mediation analysis of loneliness and perceived social support.

Background: Social anxiety has been a burning problem among contemporary college students in China. Increasing evidence suggests that individual circadian typology-chronotype may play an important role in the development of social anxiety. However, little research has focused directly on examining the association between chronotype and social anxiety, and less is known about the mediating and moderating mechanisms underlying this relationship.

Multimodal targeting chimeras enable integrated immunotherapy leveraging tumor-immune microenvironment.

Although immunotherapy has revolutionized cancer treatment, its efficacy is affected by multiple factors, particularly those derived from the complexity and heterogeneity of the tumor-immune microenvironment (TIME). Strategies that simultaneously and synergistically engage multiple immune cells in TIME remain highly desirable but challenging. Herein, we report a multimodal and programmable platform that enables the integration of multiple therapeutic modules into single agents for tumor-targeted co-engagement of multiple immune cells within TIME.

A Bimetallic Metal-Organic-Framework-Based Biomimetic Nanoplatform Enhances Anti-Leukemia Immunity via Synchronizing DNA Demethylation and RNA Hypermethylation.

Epigenetic-alterations-mediated antigenicity reducing in leukemic blasts (LBs) is one of the critical mechanisms of immune escape and resistance to T-cell-based immunotherapy. Herein, a bimetallic metal-organic framework (MOF)-based biomimetic nanoplatform (termed as AFMMB) that consists of a DNA hypomethylating agent, a leukemia stem cell (LSC) membrane, and pro-autophagic peptide is fabricated. These AFMMB particles selectively target not only LBs but also LSCs due to the homing effect and immune compatibility of the LSC membrane, and induce autophagy by binding to the Golgi-apparatus-associated protein.

Glycyrrhetinic acid nanoparticles combined with ferrotherapy for improved cancer immunotherapy.

Programmed cell death protein 1 (PD-1)/Programmed Cell Death Ligand 1 (PD-L1) blockade immunotherapy has emerged as a promising strategy to treat both solid and hematological malignancies. Despite the considerable therapeutic effects obtained in pre-clinical and clinical studies, PD-1/PD-L1 blockade therapy is still limited by the low benefit rates and a large number of patients still do not respond to this treatment. In this study, we developed a highly efficient and cancer-specific immunogenic cell death nanoinducer for effective tumor immunotherapy.

Glutathione-Bioimprinted Nanoparticles Targeting of N6-methyladenosine FTO Demethylase as a Strategy against Leukemic Stem Cells.

The N6-methyladenosine (m A) demethylase FTO plays an oncogenic role in acute myeloid leukemia (AML). Despite the promising recent progress for developing some small-molecule FTO inhibitors, the clinical potential remains limited due to mild biological function, toxic side effects and low sensitivity and/or specificity to leukemic stem cells (LSCs). Herein, FTO inhibitor-loaded GSH-bioimprinted nanocomposites (GNPIPP12MA) are developed that achieves targeting of the FTO/m A pathway synergized GSH depletion for enhancing anti-leukemogenesis.

Gold Nanorods Exhibit Intrinsic Therapeutic Activity via Controlling 6-Methyladenosine-Based Epitranscriptomics in Acute Myeloid Leukemia.

Reprograming the 6-methyladenosine (mA) landscape is a promising therapeutic strategy against recalcitrant leukemia. In this study, we synthesized gold nanorods (GNRs) of different aspect ratios using a binary surfactant mixture of hexadecyltrimethylammonium bromide and sodium oleate. Following surface functionalization with chitosan and a 12-mer peptide, GNRa-CSP12 measuring 130 × 21 nm was selectively taken up by leukemia cells via targeted endocytosis.

Photothermal therapy mediated by gold nanocages composed of anti-PDL1 and galunisertib for improved synergistic immunotherapy in colorectal cancer.

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide. The primary treatment for CRC is surgical resection, along with chemotherapy in more advanced or inoperable cases. There is a growing interest to complement both curative and palliative treatment with immunotherapies such as the programmed cell death-1 (PD-1) and PD-ligand 1 (PDL1) checkpoint inhibitors and transforming growth factor (TGF) β inhibitors.

Ataxia telangiectasia mutated inhibitor-loaded copper sulfide nanoparticles for low-temperature photothermal therapy of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the most frequent type of primary liver cancer, and is ranked the sixth most common neoplasm and the third leading cause of cancer-related deaths. Photothermal therapy (PTT) for thermal ablation of local tumors has recently emerged as a therapeutic strategy. However, the relatively high temperature of over 50 °C may lead to unexpected heat-related damage to tumor-adjacent normal tissues.

Phytotoxicity of ionic liquids with different structures on wheat seedlings and evaluation of their toxicity attenuation at the presence of modified biochar by adsorption effect.

The toxic effects of eight common ionic liquids (ILs) on wheat seedlings was evaluated with specific emphasis on the influence of concentration range, anion species and cation chain length of ILs. The growth of wheat seeds was significantly inhibited by ILs, especially under higher concentration, presence of the fluoride anion and the longer alkyl chain length of the cation. The modified biochar (PB-K-N) efficiently removed the ILs from aqueous solutions, the order of the adsorption capacities was as follows: [Bmim]OAc [Bmim]CHO [Bmim]BF [Bmim]Br, [Domim]Br [BPy]Br [Omim]Br [Bmim]Br [Emim]Br.
