Background: Steroid-induced osteonecrosis of the femoral head (SIONFH) is a universal hip articular disease and is very hard to perceive at an early stage. The understanding of the pathogenesis of SIONFH is still limited, and the identification of efficient diagnostic biomarkers is insufficient. This research aims to recognize and validate the latent exosome-related molecular signature in SIONFH diagnosis by employing bioinformatics to investigate exosome-related mechanisms in SIONFH.

Introduction: Laennec's capsule serves as a critical anatomical landmark in anatomical liver resection. Despite its potential, a lack of large-scale prospective studies limits the widespread use of the Laennec approach for minimally invasive hepatectomy. This multicenter cohort study aimed to compare the outcomes of the traditional and Laennec approaches in minimally invasive anatomical hepatectomy across multiple centers in China.

Salt enhances flavor and salinity in Chinese curing; however, excessive use can pose health risks, while reducing NaCl may harm taste. This study utilized targeted and untargeted metabolomics to investigate the intrinsic molecular mechanisms that drive flavor formation in cured sea bass subjected to salt. Glycine, succinic acid, lactic acid and uridine significantly contributed to the taste profile of the cured sea bass.

Radionuclides used for imaging and therapy can show high molecular specificity in the body with appropriate targeting ligands. We hypothesized that local energy delivered by molecularly targeted radionuclides could chemically activate prodrugs at disease sites while avoiding activation in off-target sites of toxicity. As proof of principle, we tested whether this strategy of radionuclide-induced drug engagement for release (RAiDER) could locally deliver combined radiation and chemotherapy to maximize tumor cytotoxicity while minimizing off-target exposure to activated chemotherapy.

The regulation of reaction rate differentiation, catalytic precursor differentiation, and end-product differentiation during enzyme-mediated reactions within complex lipid systems is a key area of research in flavor regulation. A multilayer lipid oxidation model, utilizing Plaice bone oil (PBO), lipase, and lipoxygenase, was employed to investigate oxidation differences between various lipids and corresponding flavor formation patterns. Lipase treatment resulted in higher levels of non‑oxygenated volatile compounds and saturated aldehydes, whereas lipoxygenase treatment increased oxygenated compounds, particularly (E)-2-hexenal, 1-penten-3-one, and 2-pentylfuran.

Propranolol, a medication used to treat cardiovascular diseases, can be harmful when overdosed and hazardous to ecosystems if released into the environment. Here, a new molecularly imprinted fluorescent sensor was developed from carbon dots through a sol-gel method. Carbon dots served as both the fluorescent signal and the carrier, with propranolol as the template molecule and 3-aminopropyltriethoxysilane as the functional monomer to be grafted on carbon dots' surface.

Intervertebral disc degeneration (IVDD) is the leading cause of low back pain, where degeneration and death of nucleus pulposus cells within the intervertebral disc (IVD) can be obviously revealed. This degeneration can result in an imbalance in the extracellular matrix due to the loss of proteoglycans and water content, which can further lead to catabolic and anabolic dysfunction of the IVD. Recently, the dysfunction of cartilage endplate (CEP) during aging has drawn large attention due to its essential functions in contributing nutrient exchange and maintaining IVD homeostasis.

Triterpenoids are the major active constituents of licorice, a well-known traditional medicinal herb. Licorice triterpenoids, represented by glycyrrhizin and glycyrrhetic acid, have a high structural diversity and are excellent lead compounds for the development of potent pharmaceuticals. However, their further application can be limited by insufficient activities, low bioavailability, and the presence of side effects, as well as the inefficiency of traditional plant extraction processes for compound production.

We report the case of a 32-year-old female patient who presented with worsening symptoms of bloody diarrhea, abdominal pain, and fever. Based on the clinical presentation, colonoscopy findings, and CT imaging, the patient underwent colectomy for suspected intestinal perforation. Histopathological examination and immunohistochemistry analysis of the resected specimen ultimately led to the diagnosis of primary intestinal NK/T-cell lymphoma.

Wetland restoration can promote the recovery of ecosystem services. However, an increasing number of reports indicate that phosphorus leaching risk occurs in downstream water bodies during the early stages of agricultural utilized wetland restoration, it is unclear that whether this phenomenon depend on temporal dynamics. Therefore, in this study, we used soil phosphorus fractions and stoichiometry as indicators to investigate soil phosphorus leaching and examine their evolution during both short- and long-term wetland restoration, aiming to identify the key driving factors.

Background: Parkinson's disease (PD) is currently the second most common degenerative neurological disorder globally, with aspiration pneumonia caused by difficulty swallowing being the deadliest complication. The patient's subjective experience and the safety of swallowing have been the main focus of previous evaluations and treatment plans. The effectiveness of treatment may be attributed to the brain's ability to adapt and compensate.

Liver ischemia-reperfusion (I/R) injury is a clinically relevant pathophysiological process that determines the effectiveness of life-saving liver transplantation, to which aberrant ROS accumulation plays a key role. In the present study we investigated the role of SUV39H1, a lysine methyltransferases, in this process focusing on regulatory mechanism and translational potential. We report that SUV39H1 expression was up-regulated in the liver tissues of mice subjected to ischemia-reperfusion and in hepatocytes exposed to hypoxia-reoxygenation (H/R) in a redox-sensitive manner.

Liver cirrhosis, a common liver disease, currently lacks specific targeted therapies. This study investigates the potential therapeutic effects of serum circulating proteins on cirrhosis from a genetic perspective, and identified six associated plasma proteins (SERPINA1, PSG5, NCAN, APOE, ADH1B, GM2A). To search for therapeutic drugs associated with circulating proteins, databases such as DrugBank and DGIdb are utilized.

Hepatocellular carcinoma (HCC) is characterized by frequent intrahepatic and distant metastases, resulting in a poor prognosis for patients. Epithelial-mesenchymal transition (EMT) plays a pivotal role in this process. However, the expression of NOP2/Sun RNA methyltransferase 5 (NSUN5) in HCC and its role in mediating EMT remain poorly understood.

Tim-1 (T-cell immunoglobulin and mucin domain 1), also known as Kim-1 (kidney injury molecule 1) or hepatitis A virus cellular receptor 1 (HAVCR1), is a transmembrane protein expressed on various immune and epithelial cells. It plays a role in modulating inflammatory and immune responses. In this study, we find that Tim-1 is overexpressed in hepatocellular carcinoma (HCC) samples and that its expression is significantly correlated with postoperative survival.

Article Synopsis
  • Gastric cancer is a significant health issue worldwide, and this study explores the impact of fatty acid metabolism on the disease to improve clinical decisions by analyzing gene subtypes through public databases and machine learning.
  • The researchers identified 71 differentially expressed genes (DEGs) related to fatty acid metabolism, creating two gene subtypes (C1 and C2) and found notable differences in immune responses between them.
  • A prognostic model was developed based on these gene subtypes, allowing for classification of patients into high-risk and low-risk groups; this model can aid clinicians in evaluating patient prognosis and making informed treatment decisions.

Short-chain fatty acids (SCFAs), which are saturated fatty acids consisting of six or fewer carbon atoms, have been found to be closely associated with the biological behavior of malignant tumors. This manuscript provides a comprehensive review on the role of SCFAs in regulating cell cycle, apoptosis, tumor angiogenesis, epithelial-mesenchymal transition, protein regulatory pathways, and histone regulation in promoting the development of malignant tumors. Furthermore, we discuss the potential therapeutic strategies targeting SCFAs for treating malignant tumors.
