Spatial metabolomics and feature-based molecular networking to unveiling in-situ quality markers landscape and reflecting geographic origins of pomegranate seeds.

Pomegranate seeds, a by-product of pomegranate processing, are gaining attention in food industries due to their high antioxidant activity. However, the lack of quality markers reflecting activity and spatial characteristics limits their utilization and product stability. In this research, a selective and sensitive method integrating ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry with feature-based molecular networking, and desorption electrospray ionization-mass spectrometry imaging developed to identify components and locate in-situ images of quality markers via spatial metabolomics analysis.

MDM2 up-regulates the energy metabolism in NSCLC in a p53-independent manner.

Although an E3 ligase MDM2 is the major negative regulator of the p53 tumor suppressor, a growing body of evidence suggests its p53-independent oncogenic properties. In particular, MDM2 has been shown to regulate serine metabolism independently of p53 status in several types of neoplasia, including NSCLC. Using the GSEA approach and publicly available molecular data on NSCLC tumors, our bioinformatics data suggest that MDM2 affects a number of metabolic genes, particularly those encoding components of the electron transport chain (ETC).

Isolation and biomimetic synthesis of acylphloroglucinol meroterpenoids as anti-breast cancer agents from .

Two new acylphloroglucinol-nerolidol meroterpenoids (APNMs) [(±)-1 and (±)-2], with a skeleton of mixed sesquiterpene and dimeric acylphloroglucinol biosynthetic origin, were isolated from the medicinal pteridophyte . Inspired by the proposed biosynthetic pathway, we initially completed the biomimetic syntheses of eight optically active APNMs (1-8) in a one-pot domino reaction. The structures of APNMs 1-8 including their absolute configurations were unambiguously established by a combination of NMR analysis, ECD calculations, and synthetic methods.

fertilization-induced extreme hypertriglyceridemia with secondary acute pancreatitis in emergency department: A case report and literature review.

Highly specific GSH-triggered bifunctional molecules to enable precise imaging and targeted therapy of cancer.

The utilization of diagnostic-integrated molecules can enable targeted delivery and controlled release to significantly enhance therapeutic effectiveness and minimize toxic effects. Herein, we developed a novel class of glutathione (GSH)-activated bifunctional molecules that respond to elevated levels of GSH in tumor microenvironment. These bifunctional molecules retained the pharmacodynamic effects of parent molecules and mitigated cytotoxicity.

Platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio as predictors of refractory anaphylaxis.

Background: Refractory anaphylaxis poses an ongoing, lethal hypersensitivity response that unpredictably involves multiple organs despite appropriate intramuscular (IM) adrenaline injections. Studies on the association of the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) concerning anaphylactic severity have yet to be carried out. The study aimed to evaluate the association between blood PLR and NLR levels and refractory anaphylaxis.

Comparative efficacy of therapeutic plasma exchange and insulin in hypertriglyceridemia-induced acute pancreatitis.

Introduction: Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) presents a therapeutic challenge with no currently definitive treatment, including therapeutic plasma exchange (TPE) and insulin. TPE aims to quickly reduce serum triglyceride (TG); however, its efficacy lacks convincing evidence. Intravenous insulin is a promising and convenient alternative, while comparative data is limited.

Prognostic Value of Acute Gastrointestinal Injury Combined with Disease Severity Scores in Critically Ill Patients.

With the sample size of 71,981 adults aged 15+ throughout 30 provinces and cities in Vietnam, data was collected using the Global Adult Tobacco Survey (GATS) questionnaire.

All-in-one nanotheranostic platform based on tumor microenvironment: new strategies in multimodal imaging and therapeutic protocol.

Conventional tumor diagnosis and treatment approaches have significant limitations in clinical application, whereas personalized theranostistic nanoplatforms can ensure advanced diagnosis, precise treatment, and even a good prognosis in cancer. Tumor microenvironment (TME)-targeted therapeutic strategies offer absolute advantages in all aspects compared to tumor cell-targeted therapeutic strategies. It is essential to create a TME-responsive all-in-one nanotheranostic platform to facilitate individualized tumor treatment.

Recent Advances in Signaling Pathways and Kinase Inhibitors for Leukemia Chemotherapy.

Leukemia is a malignant clonal disease of hematopoietic stem cells, which accounts for about 3% of the total incidence of tumors and is particularly prevalent among children and adolescents. It mainly includes four types of leukemia, namely ALL, AML, CLL, and CML, which are often aggressive and challenging diseases to treat. Several signaling pathways are dysregulated in almost all types of leukemia, such as JAK, PI3K, and MAPK, and others are dysregulated in specific types of leukemia, like Wnt/β-catenin, Hedgehog, FLT3, Bcr-Abl, and so on.

Nondestructive rapid identification of wild Cordyceps sinensis with portable instrument.

Introduction: Cordyceps sinensis (CS) is a precious medicinal fungus. Wild CS (WCS) and artificial CS (ACS) are destroyed for their identification using traditional methods, which are time consuming and labor-intensive. Therefore, it is crucial to establish a nondestructive identification method to rapidly screen WCS.

A bifunctional agent for efficient imaging of PD-L1 and antimelanoma activity.

Immune checkpoint inhibitors targeting PD-L1 lead to challenging patterns of efficacy and toxicity.
