A N7-methylguanosine modified circular RNA, circIPP2A2, promotes malignant behaviors in hepatocellular carcinoma by serving as a scaffold in modulating the Hornerin/PI3K/AKT/GSK3β axis.

Despite the advancements in treatment strategies, the long-term survival of hepatocellular carcinoma (HCC) is still pessimistic. Therefore, understanding the mechanisms of hepatocellular carcinoma may offer substantial benefits for patients. Our previous research has revealed that Hornerin promoted HCC progression by regulating the AKT signaling pathway.

METTL3 and IGF2BP2 coordinately regulate FOSL1 mRNA via m6A modification, suppressing trophoblast invasion and contributing to fetal growth restriction.

Fetal growth restriction (FGR) increases the risk of short-term and long-term complications. Widespread N6-methyladenosine (m6A) modifications on mRNAs have been found to be involved in various biological processes. However, the role of m6A modification in the pathogenesis of FGR remains elusive.

Matching Pursuit Network: An Interpretable Sparse Time-Frequency Representation Method Toward Mechanical Fault Diagnosis.

Rotatory machinery commonly operates in complex environments with strong noise and variable working conditions. Time-frequency representation offers a valuable method for capturing and analyzing nonstationary characteristics, making it particularly suitable for identifying transient fault-related features. However, despite these advantages, extracting robust and interpretable fault features in machinery operating under variable speeds remains a challenge with existing techniques.

Placenta-specific CYP11A1 overexpression lead to autism-like symptom in offspring with altered steroid hormone biosynthesis in the placenta-brain axis and rescued by vitamin D intervention.

Alterations in steroid hormone regulation have been implicated in the etiology and progression of autism spectrum disorders (ASD), with the enzyme cytochrome P450 family 11 subfamily A member 1 (CYP11A1)-a key catalyst in cholesterol side-chain cleavage, prominently expressed in the adrenal glands, ovaries, testes, and placenta-standing at the forefront of these investigations. The potential link between aberrations in placental Cyp11a1 expression and the resultant neurodevelopmental disorders, along with the mechanisms underpinning such associations, remains inadequately delineated. In this study, we employed a placental trophoblast-specific Cyp11a1 Hipp11 (H11) knock-in murine model to dissect the phenotypic manifestations within the placenta and progeny, thereby elucidating the underlying mechanistic pathways.

Stem Cell-Based Strategies: The Future Direction of Bioartificial Liver Development.

Acute liver failure (ALF) results from severe liver damage or end-stage liver disease. It is extremely fatal and causes serious health and economic burdens worldwide. Once ALF occurs, liver transplantation (LT) is the only definitive and recommended treatment; however, LT is limited by the scarcity of liver grafts.

Laparoscopic Anterior Right Hepatectomy: A Single-Center Experience.

Laparoscopic anterior right hepatectomy (LARH) has been used in some hospitals. However, data on the feasibility and safety of this procedure are still limited, due to the demanding technical requirements. The primary objective of this study was to compare the clinical outcomes of LARH with those of laparoscopic conventional right hepatectomy (LCRH) in patients with large right hepatocellular carcinoma, as well as to confirm the safety and feasibility of LARH.

A simple and efficient strategy for cell-based and cell-free-based therapies in acute liver failure: hUCMSCs bioartificial liver.

Acute liver failure (ALF) is a life-threatening condition. Cell-based and cell-free-based therapies have proven to be effective in treating ALF; however, their clinical application is limited by cell tumorigenicity and extracellular vesicle (EV) isolation in large doses. Here, we explored the effectiveness and mechanism of umbilical cord mesenchymal stem cells (hUCMSCs)-based bioartificial liver (hUCMSC-BAL), which is a simple and efficient strategy for ALF.

Aberrant expression of circular RNA DHPR facilitates tumor growth and metastasis by regulating the RASGEF1B/RAS/MAPK axis in hepatocellular carcinoma.

Background: Circular RNAs (circRNAs) are noncoding RNAs. Accumulating evidence suggests that circRNAs play a critical role in human biological processes, especially tumorigenesis, and development. However, the exact mechanisms of action of circRNAs in hepatocellular carcinoma (HCC) remain unclear.

Plasma-only circulating tumor DNA analysis detects minimal residual disease and predicts early relapse in hepatocellular carcinoma patients undergoing curative resection.

Background: Minimal residual disease (MRD) is considered an essential factor leading to relapse within 2 years (early relapse) after radical surgery, which is challenging to be detected by conventional imaging. Circulating tumor DNA (ctDNA) provides a novel approach for detecting MRD and predicting clinical outcomes. Here, we tried to construct a fixed panel for plasma-only ctDNA NGS to enable tumor-uninformed MRD detection in hepatocellular carcinoma (HCC).

Virome and metagenomic analysis reveal the distinct distribution of microbiota in human fetal gut during gestation.

Studies have shown that fetal immune cell activation may result from potential exposure to microbes, although the presence of microbes in fetus has been a controversial topic. Here, we combined metagenomic and virome techniques to investigate the presence of bacteria and viruses in fetal tissues (small intestine, cecum, and rectum). We found that the fetal gut is not a sterile environment and has a low abundance but metabolically rich microbiome.

[Latest Research Findings on Prediction of Preeclampsia in Pregnant Women Based on Analysis of Cell-Free RNA in Peripheral Blood].

Preeclampsia gravely threatens the health of mothers and infants. At present, treatment based on the relevant mechanisms of pathogenesis is still not available, and there is no independent reliable clinical index for early prediction of preeclampsia. According to recent studies, analysis of the cell-free RNA in the peripheral blood of pregnant women has shown that testing certain cell-free RNA levels can help predict in advance the occurrence of preeclampsia before clinical symptoms appear.

[Preeclampsia: An Obstetrician's Perspective].

Preeclampsia-eclampsia is a common obstetric critical disease and obstetricians have studied it assiduously for hundreds of years. We have attempted to explore the etiology, pathology, prevention, intervention, and treatment of preeclampsia-eclampsia, but we still have not arrived at a thorough understanding of its causes, and it is difficult to find effective prevention and treatment methods. Although the research process has been fraught with difficulties and frustrations, we are nonetheless gradually gaining a better understanding of the disease.

Bloodless Laparoscopic Partial Splenectomy Assisted by Bipolar Radiofrequency Excision Hemostatic Device.

Among the lymphatic system in the human body, the spleen is the most extensive one and has hematopoietic, hemofiltration, blood storage, and immune functions. As a new method of preserving the spleen, laparoscopic partial splenectomy (LPS) has been increasingly applied in clinical practice with people's deeper insights into minimally invasive treatment and the development of technical equipment. Compared with conventional open splenectomy, LPS can preserve normal spleen tissue as much as possible, decrease the occurrence of complications after total splenectomy, and reduce postoperative hospital stay.
