Baseline and interim F-FDG PET/CT metabolic parameters predict the efficacy and survival in patients with diffuse large B-cell lymphoma.

Introduction: The prognostic value of 18F-FDG PET/CT metabolic parameters, such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG), in diffuse large B-cell lymphoma (DLBCL) remains inadequately explored. This study aims to assess the correlation between these parameters and patient outcomes.

Methods: A cohort of 156 DLBCL patients underwent 18F-FDG PET/CT imaging at baseline and after 3-4 cycles of R-CHOP or CHOP-like regimen.

ALB-PRF facilitates chondrogenesis by promoting chondrocytes migration, proliferation and differentiation.

Cartilage injury is common in orthopedics and cartilage tissue engineering provides a therapeutic direction for cartilage regeneration. Albumin (ALB)-platelet-rich fibrin (PRF) is speculated to be an ideal natural scaffold material for cartilage tissue engineering theoretically as a product derived from human venous blood. Through and experiments, it was demonstrated that ALB-PRF displayed porous structure and slowly released growth factors (TGF-β1, PDGF-AA, PDGF-AB, PDGF-BB, EGF, IGF-1 and VEGF), ALB-PRF conditioned media promoted proliferation, migration, adhesion, phenotype maintenance and extracellular matrix secretion of rabbit chondrocytes.

TIPE2 aggravates experimental colitis and disrupts intestinal epithelial barrier integrity by activating JAK2/STAT3/SOCS3 signal pathway.

Ulcerative colitis (UC) is a chronic relapsing and progressive inflammatory disease of the colon. TIPE2 is a negative regulator of innate and adaptive immunity that maintains immune homeostasis. We found that TIPE2 was highly expressed in mucosa of mice with colitis.

Iron Single-Atom Nanozyme with Inflammation-Suppressing for Inhibiting Multidrug-Resistant Bacterial Infection and Facilitating Wound Healing.

Infection with drug-resistant bacteria and the formation of biofilms are the main factors contributing to wound healing insufficiency. Antibacterial agents with enzyme-like properties have exhibited considerable potential for efficient eradication of drug-resistant microorganisms due to their superior sensitivities and minimal side effects. In this work, we prepared a kind of Fe-centered single-atom nanozyme (Fe-SAzyme) with high biocompatibility and stability via a facile one-pot hydrothermal method, which was suitable for the treatment of wounds infected with drug-resistant bacteria.

Materials And Methods: Immunohistochemical method was used to investigate the expression of METTL3 in the human oral malignant transformation. Bioinformatics analysis was used to explore the role of METTL3 in oral malignant transformation.

Toward 95.5% Efficient Red Emissive Carbon Dots: Oxidation State Enhancing Radiative Electron-Transition of Indole Fluorophore.

Red fluorescence carbon dots (CDs) are promising for diverse applications and have attracted tremendous research interest. However, it is still challenging to achieve red fluorescence CDs with high fluorescence quantum yields (QYs > 50%). Herein, three kinds of red fluorescence CDs with QYs of 53.

Van der Waals Epitaxy of High-Quality Transition Metal Dichalcogenides on Single-Crystal Hexagonal Boron Nitride.

Van der Waals (vdW) heterostructures comprising of transition metal dichalcogenides (TMDs) and hexagonal boron nitride (h-BN) are promising building blocks for novel 2D devices. The vdW epitaxy provides a straightforward integration method for fabricating high-quality TMDs/h-BN vertical heterostructures. In this work, the vdW epitaxy of high-quality single-crystal HfSe on epitaxial h-BN/sapphire substrates by chemical vapor deposition is demonstrated.

SET facilitates immune escape of microsatellite stability colorectal cancer by inhibiting c-Myc degradation.

Microsatellite stability (MSS) colorectal cancer (CRC) exhibits a low mutation load and poor immunogenicity, contributing to immune escape of tumor cells and less benefit from immune checkpoint blockade (ICB) treatment. The mechanisms underlying immunotherapeutic resistance in MSS CRC remain to be elucidated. Here, we identified that nuclear proto-oncogene SET is significantly higher expressed in MSS CRC compared to microsatellite instability (MSI) CRC and facilitates immune escape of MSS CRC.

Ecohydrological changes recorded by sedimentary diatoms in the Dajiuhu Wetland in Shennongjia over the past 40 years.

Anthropogenic hydrological regulation is profoundly altering the structure and function of wetland ecosystems. Due to the scarcity of long-term monitoring records, the responses of wetland ecosystems to anthropogenic hydrological regulation remain unclear. We reconstructed past ecohydrological changes in Dajiuhu Wetland during the last 40 years and explored the driving forces, based on multiproxy records of a 44-cm-length sediment core collected from Wuhaohu Lake of Dajiuhu Wetland in Shennongjia, Hubei.

SESN2 Ameliorates Dihydrotestosterone-induced Human Ovarian Granulosa Cell Damage by Activating AMPK/ULK1-mediated Mitophagy.

Sestrin 2 (SESN2) has been reported to participate in the regulation of granulosa cell function in ovarian tissues. However, the role of SESN2 in polycystic ovarian syndrome (PCOS) is still incompletely understood. Here, we investigated the functional role and mechanism of SESN2 in dihydrotestosterone (DHT)-induced granulosa cells.

MASER: Enhancing EEG Spatial Resolution With State Space Modeling.

Consumer-grade Electroencephalography (EEG) devices equipped with few electrodes often suffer from low spatial resolution, hindering the accurate capture of intricate brain activity patterns. To address this issue, we propose MASER, a novel super-resolution approach for EEG recording. In MASER, we design the eMamba block for extracting EEG features based on the principles of state space models (SSMs).
