Rutaecarpine alleviates migraine in nitroglycerin-induced mice by regulating PTEN/PGK1 signaling pathway to activate NRF2 antioxidant system.

Background: Due to its widespread prevalence, migraine is a common neurovascular condition that has a major impact on people's health and quality of life. Rutaecarpine (RUT) is one of the main effective components of Evodia rutaecarpa, which has a wide range of biological activities. However, the exact mechanism by which RUT improves migraine remain unknown.

Analysis of the efficacy of a single subumbilical stoma for bilateral cutaneous ureterostomy after radical cystectomy.

Background: Radical cystectomy and urinary diversion are the standard surgical treatments for patients with muscle-invasive or high-risk, or recurrent non-muscle-invasive bladder cancer. Although this approach significantly prolongs patient survival, it can lead to postoperative complications. This study aims to compare the efficacy and complications of bilateral cutaneous ureterostomy with a single subumbilical stoma to those of cutaneous ureterostomy with two stomas and an ileal conduit as a means of urinary diversion after radical cystectomy.

11β-Hydroxysteroid Dehydrogenase Type 1 Facilitates Osteoporosis by Turning on Osteoclastogenesis through Hippo Signaling.

11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) is a key enzyme that transform cortisone to cortisol, which activates the endogenous glucocorticoid function. 11β-HSD1 has been observed to regulate skeletal metabolism, specifically within osteoblasts. However, the function of 11β-HSD1 in osteoclasts has not been elucidated.

The training dataset consisted of 5892 WLI images from 1283 patients, and the validation dataset included 4529 images from 1224 patients.

Comprehensive transcriptomic analyses identify KDM genes-related subtypes with different TME infiltrates in gastric cancer.

However, the relationship between KDMs and formation of tumor microenvironment (TME) in gastric cancer (GC) remain unclear and need to be comprehensively analyzed.In the present study, 24 KDMs were obtained and consensus molecular subtyping was performed using the "NMF" method to stratify TCGA-STAD into three clusters.

Hypoxia-elicited Exosomes Promote the Chemoresistance of Pancreatic Cancer Cells by Transferring LncROR via Hippo Signaling.

Recent studies have found that hypoxia contributes to tumor progression and drug resistance by inducing the secretion of exosomes. However, the mechanism underlying this resistance in pancreatic cancer remains to be explored. In this study, we investigated the effect of hypoxia-induced tumor-derived exosomes (Hexo) on stemness and resistance to gemcitabine in pancreatic cancer cells, as well as the molecular mechanisms involved in this process.

Recent advances of long non-coding RNAs in control of hepatic gluconeogenesis.

Gluconeogenesis is the main process for endogenous glucose production during prolonged fasting, or certain pathological conditions, which occurs primarily in the liver. Hepatic gluconeogenesis is a biochemical process that is finely controlled by hormones such as insulin and glucagon, and it is of great importance for maintaining normal physiological blood glucose levels. Dysregulated gluconeogenesis induced by obesity is often associated with hyperglycemia, hyperinsulinemia, and type 2 diabetes (T2D).

The Active Fraction of Polyrhachis vicina Roger (AFPR) activates ERK to cause necroptosis in colorectal cancer.

Ethnopharmacological Relevance: Polyrhachis vicina Roger (P. vicina), a traditional Chinese medicinal animal, has been used to treat rheumatoid arthritis, hepatitis, cancer, and other conditions. Due to its anti-inflammatory properties, our previous pharmacological investigations have demonstrated that it is effective against cancer, depression, and hyperuricemia.

An fMRI study of visual geometric shapes processing.

Cross-modal correspondence has been consistently evidenced between shapes and other sensory attributes. Especially, the curvature of shapes may arouse the affective account, which may contribute to understanding the mechanism of cross-modal integration. Hence, the current study used the functional magnetic resonance imaging (fMRI) technique to examine brain activity's specificity when people view circular and angular shapes.

Traditional Chinese Manual Therapy (Tuina) reshape the function of default mode network in patients with lumbar disc herniation.

Purpose: Investigating the changes of regional homogeneity (ReHo) values and both static and dynamic functional connectivity (FC) before and after Traditional Chinese Manual Therapy (Tuina) in patients with lumbar disk herniation (LDH) through resting-state functional magnetic resonance imaging (RS-fMRI). Based on this, we observe the effect of Tuina on the above abnormal changes.

Methods: Patients with LDH ( = 27) and healthy controls (HCs) ( = 28) were recruited.

Regional abnormalities of spontaneous brain activity in migraine: A coordinate-based meta-analysis.

Amplitude of low-frequency fluctuation after taste exposure revealed by resting-state fMRI.

Taste perception has been deeply explored from the behavioural level to delineating neural mechanisms. However, most previous studies about the neural underpinnings of taste perception have focused on task-related brain activation. Notably, evidence indicates that task-induced brain activation often involves interference from irrelevant task materials and only accounts for a small fraction of the brain's energy consumption.

USP51/ZEB1/ACTA2 axis promotes mesenchymal phenotype in gastric cancer and is associated with low cohesion characteristics.

poorly cohesive (PC) gastric cancer (GC) (PC-GC) is a distinct histological subtype of GC and is defined as a tumor consisting of isolated or small clusters of tumor cells with poorly differentiated and metastatic characteristics. According to multiple studies, PC-GC is intrinsically heterogeneous, with mesenchymal variants being the most aggressive. However, to date, the molecular mechanisms associated with PC-GC are still not fully understood.

Exosomes from Inflamed Macrophages Promote the Progression of Parkinson's Disease by Inducing Neuroinflammation.

Inflammation is a common feature both for Parkinson's disease (PD) and obesity-associated metabolic syndromes. Inflammation mediated by inflamed macrophages in white adipose tissue plays a pivotal role for the pathogenesis of metabolic syndromes. Exosomes are important carriers connecting peripheral tissues and the central nervous system (CNS).

A Rare Case of Thymic Rosai-Dorfman Disease Mimicking Malignancy on F-FDG PET/CT.
