UPLC-ESI-MS/MS-based chemometric approach for investigating the effect of conventional versus modern extraction methods on polyphenols recovery from grape seed wastes.

Grape seed wastes are a rich source of bioactive polyphenols. This study compares the recovery efficiency of traditional maceration extraction (ME) with modern extraction techniques (ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), and accelerated solvent extraction (ASE)), revealing the selective extraction of polyphenolic compounds by different methods. UPLC-ESI-MS/MS analysis was used to identify and quantify 24 polyphenols.

Vitamin C prevents myricetin degradation in boiling water by reducing ortho-quinone intermediates.

Myricetin, a bioactive flavonoid, degrades rapidly in boiling water, limiting its use in functional foods and pharmaceuticals. This study explores the protective effect of vitamin C on the thermal degradation of myricetin and its mechanism of action. O-phenylenediamine derivatization identified reactive ortho-quinone intermediates, while density functional theory (DFT) calculations (ΔG = -47.

Case report: A successful case of targeted immunotherapy for locally advanced pancreatic cancer under non-surgical conditions.

Introduction: Locally advanced pancreatic cancer (LAPC) is a borderline unresectable malignancy that presents significant treatment challenges. The management of LAPC remains a complex issue, particularly in patients who are not eligible for surgical resection.

Case: Here, we report the case of a 60-year-old woman diagnosed with LAPC through pathological biopsy who subsequently underwent targeted immunotherapy following the failure of a gemcitabine, oxaliplatin, and S-1 (G&S) chemotherapy regimen.

Exploring the mechanism of flavonoids modification by dimerization strategies and their potential to enhance biological activity.

Flavonoid dimers are being focused due to their particular structure that links two units through CC or C-O-C bonds. This paper provides a comprehensive and systematic overview of the reaction mechanism of flavonoid dimerization and discusses their synthesis process and methods to devise an ideal preparation scheme of flavonoid dimers. Given the polyphenolic hydroxyl groups of dimerized flavonoids as well as their unique bridging molecular structures, we preliminarily explored the link between conformation and function, and discovered their several reinforced bioactivities compared to flavonoid monomers, such as hypolipidemic, antidiabetic, and neuroprotective activities as well as other potential.

Analgesia of noninvasive electrical stimulation of the dorsolateral prefrontal cortex: A systematic review and meta-analysis.

Objective: The dorsolateral prefrontal cortex (DLPFC) is implicated in pain modulation, suggesting its potential as a therapeutic target for pain relief. However, studies on transcranial electrical stimulation (tES) over the DLPFC yielded diverse results, likely due to differences in stimulation protocols or pain assessment methods. This study aims to evaluate the analgesic effects of DLPFC-tES using a meta-analytical approach.

ERCP-Related adverse events in pediatric patients: a 10-years single-site review.

Purpose: This retrospective analysis aimed to assess the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric patients by examining ERCP-related adverse events (AEs) occurring over a decade at a single center.

Methods: Pediatric patients under 18 years old who underwent ERCP at the Second Hospital of Hebei Medical University from 1/2013 to 11/2023 were included. ERCP-related AEs were defined according to ERCP-related adverse events: European Society of Gastrointestinal Endoscopy (ESGE) Guideline.

Prostaglandin F synthase promotes oxaliplatin resistance in colorectal cancer through prostaglandin F-dependent and F-independent mechanism.

Background: Oxaliplatin (Oxa) is the first-line chemotherapy drug for colorectal cancer (CRC), and Oxa resistance is crucial for treatment failure. Prostaglandin F synthase (PGF) (PGFS), an enzyme that catalyzes the production of PGF, is involved in the proliferation and growth of a variety of tumors. However, the role of PGFS in Oxa resistance in CRC remains unclear.

Transcranial random noise stimulation over the left dorsolateral prefrontal cortex attenuates pain expectation and perception.

Objective: The dorsolateral prefrontal cortex (DLPFC) has been increasingly used as a neuromodulatory target in pain management. Transcranial random noise stimulation (tRNS) was shown to effectively elevate cortical excitability. Hence, this study aimed to characterize how tRNS over the left DLPFC affects pain expectation and perception, as well as the efficacy of conditioned-pain modulation (CPM) that reflects the function of the endogenous pain-inhibitory pathway.

Identification and validation of EMT-immune-related prognostic biomarkers CDKN2A, CMTM8 and ILK in colon cancer.

Colon cancer (CC) is a disease with high incidence and mortality rate. The interaction between epithelial-mesenchymal transition (EMT) and immune status has important clinical significance. We aim to identify EMT-immune-related prognostic biomarkers in colon cancer.

Effects of High-Definition Transcranial Direct Current Stimulation Over the Primary Motor Cortex on Cold Pain Sensitivity Among Healthy Adults.

Some clinical studies have shown promising effects of transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) on pain relief. Nevertheless, a few studies reported no significant analgesic effects of tDCS, likely due to the complexity of clinical pain conditions. Human experimental pain models that utilize indices of pain in response to well-controlled noxious stimuli can avoid many confounds that are present in the clinical data.

REC8 enhances stemness and promotes metastasis of colorectal cancer through BTK/Akt/β-catenin signaling pathway.

Cancer/testis antigens (CTAs) are often aberrantly expressed in cancer stem cells (CSCs) which are responsible for tumor metastasis. Rec8 meiotic recombination protein (REC8), a member of CTAs, shares distinct roles in various cancers, while its contribution to CSCs and colorectal cancer (CRC) remains unclear. We found that overexpression of REC8 facilitated the migration and invasion of CRC cells (DLD-1 and SW480 cells) in vitro and promoted the liver metastasis of CRC in vivo.

Soluble TREM-1, as a new ligand for the membrane receptor Robo2, promotes hepatic stellate cells activation and liver fibrosis.

Triggering receptor expressed on myeloid cells-1 (TREM-1) exists in two forms: a transmembrane form and a soluble form (sTREM-1). The levels of sTREM-1 are elevated in supernatants of activated HSCs. However, the role of sTREM-1 in HSC activation and liver fibrosis remains undefined.

Y-box binding protein 1 augments sorafenib resistance the PI3K/Akt signaling pathway in hepatocellular carcinoma.

Background: Sorafenib is the first-line treatment for patients with advanced hepatocellular carcinoma (HCC). Y-box binding protein 1 (YB-1) is closely correlated with tumors and drug resistance. However, the relationship between YB-1 and sorafenib resistance and the underlying mechanism in HCC remain unknown.

Effects of transcranial direct current stimulation on experimental pain perception: A systematic review and meta-analysis.

Objective: Many studies have examined the effectiveness of transcranial direct current stimulation (tDCS) on human pain perception in both healthy populations and pain patients. Nevertheless, studies have yielded conflicting results, likely due to differences in stimulation parameters, experimental paradigms, and outcome measures. Human experimental pain models that utilize indices of pain in response to well-controlled noxious stimuli can avoid many confounds present in clinical data.
