Hollow-fiber-based supported liquid membrane was modified utilizing nanostructures such as graphite, graphene oxide or nitrogen-doped graphene oxide, for electro-membrane extraction (EME) of imatinib and sunitinib from biological fluids. By applying these conductive nanostructures, a low-voltage EME device (6.0 V) was fabricated. A response surface methodology through central composite design was used to evaluate and optimize effects of various essential factors that influence on normalized recovery. Optimal extraction conditions were set as, 1-octanol with 0.01 % (w/v) graphene oxide functioning as the supported liquid membrane, an extraction time of 17.0 min, pH of the acceptor and the donor phase of 2.8 and 7.9, respectively. The method was successfully applied to quantify imatinib and sunitinib in biological fluids.

Objective: This study aims to clarify angiogenesis mechanisms in ulcerative colitis and identify potential therapeutic targets.
Methods: The Gene Expression Omnibus (GEO) database was used to obtain expression profiles and clinical data for UC and healthy colon tissues. Angiogenesis-related gene sets were acquired from GeneCards.

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Recent advent of tyrosine kinase inhibitors (TKIs) has significantly improved the prognosis of GIST patients. However, responses to TKI therapy can vary depending on the specific gene mutation.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal tract, and tyrosine kinase inhibitors (TKIs) have achieved great success in the treatment of GISTs. The role and value of surgery in advanced GISTs are still controversial. This article aims to review the progress related to surgery for advanced GIST in the context of targeted therapy, particularly exploring the issues related to the combination of surgery and targeted therapy.

Gastrointestinal stromal tumors (GISTs) are rare malignant tumors that arise from the connective tissues of the gastrointestinal tract. Reports about GISTs treated with imatinib for over five years are exceedingly rare. In this case report, we present a patient with GIST who remained alive for two decades after undergoing imatinib treatment.

Purpose: The prognosis of patients with metastatic GIST and imatinib-sensitive primary mutations has significantly improved. However, limited data are available to inform patients about outcomes across different lines of treatment. This retrospective analysis aims to evaluate patient outcomes at a large German GIST referral center over the past 15 years.
