MFGE8 induces anti-PD-1 therapy resistance by promoting extracellular vesicle sorting of PD-L1.

Anti-PD-1 therapy, effective in patients with various advanced tumors, still encounters the challenge of insensitivity in most patients. Here, we demonstrate that PD-L1 on tumor cell-derived extracellular vesicles (TEVs) is critical for anti-PD-1 therapy resistance. Reducing endogenous and transferring exogenous TEVs abrogates and induces anti-PD-1 therapy resistance, respectively.

Feasibility and safety of transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) panhysterectomy: a polycentric retrospective study.

According to the operation mode, the patients were divided into two groups: the traditional multi-port laparoscopic surgery (MPLS) group (n = 45) and the Transvaginal Natural Orifice Transluminal Endoscopic Surgery (V-NOTES) group (n = 30).

CD7-targeting pro-apoptotic extracellular vesicles: A novel approach for T-cell haematological malignancy therapy.

T-cell haematological malignancies progress rapidly and have a high mortality rate and effective treatments are still lacking. Here, we developed a drug delivery system utilizing 293T cell-derived extracellular vesicles (EVs) modified with an anti-CD7 single-chain variable fragment (αCD7/EVs). Given the challenges of chemotherapy resistance in patients with T-cell malignancy, we selected cytochrome C (CytC) and Bcl2 siRNA (siBcl2) as therapeutic agents and loaded them into αCD7/EVs (αCD7/EVs/CytC/siBcl2).

Increased viperin expression induced by avian infectious bronchitis virus inhibits viral replication by restricting cholesterol synthesis: an in vitro study.

With the emergence of new variant strains resulting from high mutation rates and genome recombination, avian infectious bronchitis virus (IBV) has caused significant economic losses to the poultry industry worldwide. Little is known about the underlying mechanisms of IBV-host interactions, particularly how IBV utilizes host metabolic pathways for efficient viral replication and transmission. In the present study, the effects of the cell membrane, viral envelope membrane, and viperin-mediated cholesterol synthesis on IBV replication were explored.

The value of umbilical artery blood gas analysis in the rapid diagnosis of fetomaternal hemorrhage.

As a rare obstetric disease, fetomaternal hemorrhage (FMH) often causes severe fetal anemia, edema and even death, easily to be confused with severe neonatal asphyxia. Currently, there are several ways to detect or predict FMH, however, most of them are flawed and time-consuming, as well as unsuitable for rapid diagnosis and timely intervention of FMH. To explore the values of umbilical artery blood gas analysis in the rapid diagnosis of FMH, providing basis for rapid guidance of newborn rescue.

USP33 facilitates the ovarian cancer progression via deubiquitinating and stabilizing CBX2.

Post-translational modifications of proteins play a pivotal role in both the initiation and progression of ovarian cancer. Despite the recognition of USP33 as a significant factor in various cancers, its specific function and underlying mechanisms in ovarian cancer remain elusive. Proteomics and ubiquitinomics approaches were coupled to screen novel substrate proteins directly regulated by USP33.

Superalloys fracture process inference based on overlap analysis of 3D models.

Superalloy materials exhibit susceptibility to fracture failures stemming from the influence of thermomechanical factors. To comprehensively understand the fracture mechanisms, material properties, root causes of failure, and the subsequent optimization of alloys, a detailed analysis of the internal fracture process and the morphological traits of the fracture surface is imperative. Traditional analysis of fracture surfaces solely relies on 2D images, thus lacking crucial 3D information.

Progress on a Carbon Nanotube Field-Effect Transistor Integrated Circuit: State of the Art, Challenges, and Evolution.

As the traditional silicon-based CMOS technology advances into the nanoscale stage, approaching its physical limits, the Carbon Nanotube Field-effect Transistor (CNTFET) is considered to be the most significant transistor technology beyond Moore's era. The CNTFET has a quasi-one-dimensional structure so that the carrier can realize ballistic transport and has very high mobility. At the same time, a single CNTFET can integrate hundreds of nanowires as the conductive channels, enabling significant current transport capabilities even in low supply voltage, thereby providing a foundational basis for achieving nanoscale ultra-large-scale analog/logic circuits.

Adhesion between EVs and tumor cells facilitated EV-encapsulated doxorubicin delivery via ICAM1.

Doxorubicin (Dox) is an anti-tumor drug with a broad spectrum, whereas the cardiotoxicity limits its further application. In clinical settings, liposome delivery vehicles are used to reduce Dox cardiotoxicity. Here, we substitute extracellular vesicles (EVs) for liposomes and deeply investigate the mechanism for EV-encapsulated Dox delivery.

Establishment of a rapid real-time fluorescence-based recombinase-aided amplification method for detection of avian infectious bronchitis virus.

Infectious bronchitis (IB) is an acute, highly contagious contact respiratory disease of chickens caused by infectious bronchitis virus (IBV). IBV is very prone to mutation, which brings great difficulties to the prevention and control of the disease. Therefore, there is a pressing need for a method that is fast, sensitive, specific, and convenient for detecting IBV.

GSK3β and UCHL3 govern RIPK4 homeostasis via deubiquitination to enhance tumor metastasis in ovarian cancer.

Receptor-interacting protein kinase 4 (RIPK4) is increasingly recognized as a pivotal player in ovarian cancer, promoting tumorigenesis and disease progression. Despite its significance, the posttranslational modifications dictating RIPK4 stability in ovarian cancer remain largely uncharted. In this study, we first established that RIPK4 levels are markedly higher in metastatic than in primary ovarian cancer tissues through single-cell sequencing.
