Anandamide (AEA), an endogenous ligand of cannabinoid CB1 and CB2 receptors, which also binds transient receptor potential vanilloid type 1 receptor (TRPV1), has been shown to display substantial selective cytotoxicity toward some cancer cell lines in vitro, although the relevant data are not
Apomorphine cytotoxicity towards rat glioma C6 cells was recently demonstrated to be time- and concentration-dependent. In the present work, the mechanism of cytotoxicity of apomorphine was further studied in the C6 cell line. We showed that bovine serum albumin partially protects C6 cells against
The effect of human albumin on neuronal voltage-dependent Na+ channels was studied in NH15-CA2 neuroblastoma x glioma hybrid cells. At an albumin concentration of 32 g/l, the transient Na+ currents, elicited at 1 Hz and recorded with the whole-cell technique, were increased to 125% the control
Traditional glioma chemotherapy with those second-line drugs such as anthracyclines usually failed because they are inaccessible to blood-brain barrier (BBB) in tumor. In our study, we incorporated aclarubicin (ACL) into cationic albumin-conjugated pegylated nanoparticle (CBSA-NP-ACL) to determine
To compare the performance of macromolecular albumin gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA)30 and low molecular weight gadopentetate dimeglumine for microvessel characterization, we examined an intracranial 9L glioma model in which increased angiogenesis, hypervascularity, and
Intravenous MRI contrast agents are commonly used to improve the detection of intracranial tumors and other central nervous system (CNS) lesions for diagnosis and treatment planning. Two small-molecule, albumin-binding blood pool contrast agents (MP-2269 and MS-325) of potential clinical
Malignant gliomas remain refractory to several therapeutic approaches and the requirement for novel treatment modalities is critical to combat this disease. Etoposide is a topoisomerase-II inhibitor, which promotes DNA damage and apoptosis of cancer cells. In this study, we prepared albumin with
Biomaterial surface modification is an efficient way of improving cell-material interactions. In this study, sub-micrometer laser-induced periodic surface structures (LIPSS) were produced on polystyrene by laser irradiation. FT-IR analysis confirmed that this treatment also led to surface oxidation
The present study explored the predictive value of systemic inflammatory indexes in diagnosing grade III gliomas of oligodendroglial origin.A retrospective study of 154 patients with grade III gliomas was conducted. Systemic inflammatory indexes, including Brain tumors are hard to cure due to the life-threatening impact on the vital function areas of brain plus the blood-brain barrier caused poor drug delivery to brain. In this study, we utilized the human serum albumin (HSA) as a template to synthesize ultrasmall platinum nanoparticle for targeted
To delineate the tumor margins of malignant gliomas laser-induced fluorescence detection technique was applied using 5-aminofluorescein-albumin as the fluorescent dye. The 5-aminofluorescein was linked to serum albumin (= AFlc-SA) as a cumulative protein label using residualizing markers. In a
A total of 72 RG-2 transplanted gliomas were studied in 58 rats at three time points (1, 30, 240 min) after intravenous injection of [125I]radioiodinated serum albumin ([125I]RISA). The animals were divided into two groups: a control group that received no treatment and a second group that was
Preoperative systemic immune-inflammation index (SII) and the albumin/globulin ratio (AGR) have been used as prognostic markers in many malignancies. This study was conducted to evaluate the clinical significance of the preoperative SII and AGR in high-grade glioma (HGG) Previously, we successfully developed the c(phg-isoDGRk) peptide as a novel integrin α5β1-targeted SPECT imaging probe 99mTc-HisoDGR for Glioma imaging. However, the fast clearance of 99mTc-HisoDGR in blood reduced its tumor accumulation and retention,
Poor aqueous solubility is a serious problem for most chemotherapeutics. Docetaxel (DTX), an inhibitor of microtubule depolymerization, is frequently used to treat many malignancies. However, the surfactant used in its commercial preparation (Taxotere) has proven problematic in clinical use because
