The effects of Olea europaea leaf extract (OLE) phenolics, including oleuropein (OL), hydroxytyrosol (HT), tyrosol (TYR), and rutin against glioblastoma (GB), independently in combination with temozolomide (TMZ), were investigated T98G A172 cells. Cell growth was assessed by WST-1, real-time cell analysis, colony formation, cycle distribution assays. A dual acridine orange propidium iodide (AO/PI) staining annexin V assay determined viability. sphere-forming assay, an intracellular oxidative...

Congenital lung malformations (CLMs) refer to structural abnormalities of the lungs that occur during fetal development. Matrix metalloproteinases (MMPs) constitute a group zinc-dependent enzymes, with certain members this family playing pivotal roles in remodeling both prenatally and postnatally. This study aimed explore expression levels MMP-2, MMP-7, MMP-9 CLMs which are recognized as contributors their clinical pathology. A total 41 patients between ages 0-17 years had undergone surgery...

Metastasectomy of liver metastases colorectal cancer (CRC) offers the greatest likelihood cure. Nevertheless, recurrence rates after this procedure are high, and chemotherapy is a reasonable choice with inconclusive evidence. In our study, we aimed to investigate parameters that can be used predict development metastasectomy by examining clinical, pathological molecular markers in primary tumor their metastases. Epithelial-mesenchymal-Transition (EMT) mechanism, stem cell (CSC) RAS, mTOR,...

<title>Abstract</title> Infliximab (IFX) is widely used in the treatment of inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD). Still, long-term use may be ineffective or suggest some side effects. This study investigated role Myricetin, a flavonoid, alone its complementary therapeutic potential combination with IFX against UC, CH, cancerization. DSS triggered development acute UC syndromes Wistar albino rats, while TNBS symptoms seen CD. The...

The overall survival of patients with the advanced and recurrent gastric cancer (GC) remains unfavorable. In particular, this is due to spreading resistance chemotherapy associated epithelial-mesenchymal transition (EMT) tumor cells. EMT can be identified by transcriptome profiling GC for markers. Indeed, analysis TCGA GTEx databases (n= 408) acohortof 43) revealed that expression theCDH2gene was significantly decreased in tumors vs. non-tumor tissues correlated patients. Expression...

Total resection of glioblastoma (GB) tumors is nearly impossible, and systemic administration temozolomide (TMZ) often inadequate. This study presents a hybrid layered composite nanofiber mesh (LHN) designed for localized treatment in GB tumor bed. The LHN, consisting polyvinyl alcohol core-shell polylactic acid layers, was loaded with TMZ rutin.

To describe the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in glioblastoma (GB) progression patients concurrently diagnosed with diabetes mellitus (DM).Formalin-fixed paraffin-embedded (FFPE) tumor samples 47 GB only and 13 DM (GB-DM) were enrolled this study. Data for p53 Ki67 immunohistochemical staining tumors blood HbA1c levels retrospectively collected. MALAT1 expression was assessed using quantitative real-time polymerase chain reaction.The coexistence...
