Colon-specific controlled release of oral liposomes for enhanced chemo-immunotherapy against colorectal cancer.

A colon-specific drug delivery system has great potential for the oral administration of colorectal cancer. However, the uncontrollable fate of liposomes makes their effectiveness for colonic location, and intratumoral accumulation remains unsatisfactory. Here, an oral colon-specific drug delivery system (CBS-CS@Lipo/Oxp/MTZ) was constructed by covalently conjugating spores (CBS) with drugs loaded chitosan (CS)-coated liposomes, where the model chemotherapy drug oxaliplatin (Oxp) and anti-anaerobic bacteria agent metronidazole (MTZ) were loaded.

Performance of nutritional and inflammatory markers in patients with pancreatic cancer.

Background: Systemic inflammation and nutrition play pivotal roles in cancer progression and can increase the risk of delayed recovery after surgical procedures.

Aim: To assess the significance of inflammatory and nutritional indicators for the prognosis and postoperative recovery of patients with pancreatic cancer (PC).

Methods: Patients who were diagnosed with PC and underwent surgical resection at our hospital between January 1, 2019, and July 31, 2023, were enrolled in this retrospective observational cohort study.

Procyanidin A2, a polyphenolic compound, exerts anti-inflammatory and anti-oxidative activity in lipopolysaccharide-stimulated RAW264.7 cells.

Procyandin A2 (PCA2) is a polyphenolic compound which is isolated from grape seeds. It has been reported that PCA2 exhibits antioxidative and anti-inflammatory effects, but its molecular mechanism is still poorly understood. This study tests the hypothesis that PCA2 suppresses lipopolysaccharide (LPS)-induced inflammation and oxidative stress through targeting the nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), and NF-E2-related factor 2 (Nrf2) pathways in RAW264.

Procyanidin A1 Alleviates Inflammatory Response induced by LPS through NF-κB, MAPK, and Nrf2/HO-1 Pathways in RAW264.7 cells.

Inflammation is a complex physiological process that poses a serious threat to people's health. However, the potential molecular mechanisms of inflammation are still not clear. Moreover, there is lack of effective anti-inflammatory drugs that meet the clinical requirement.

Effect of Cyclocarya Paliurus on Hypoglycemic Effect in Type 2 Diabetic Mice.

BACKGROUND The aim of this study was to assess the hypoglycemic effect of Cyclocarya paliurus extract (CPE) on diabetes mellitus (DM) mice. MATERIAL AND METHODS A DM mouse model was established to test FBG, TC, and TG. The DM mice were divided into 3 groups: a DM group, a DM+CPE (0.

Astrocyte elevated gene-1 induces autophagy in diabetic cardiomyopathy through upregulation of KLF4.

Background: Astrocyte elevated gene-1 (AEG-1), also known as metadherin, 3D3, and lysine-rich carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) coisolated, has emerged as an important oncogene that is overexpressed in a variety of cancers. Previous studies revealed that AEG-1 is also involved in multiple physiological and pathological processes, such as development, inflammation, neurodegeneration, migraine, and Huntington's disease. However, the function of AEG-1 in diabetic cardiomyopathy (DCM) has not been reported yet.

Pharmacodynamic and pharmacokinetic characteristics of YMR-65, a tubulin inhibitor, in tumor-bearing mice.

YMR-65​, 5-(5-bromo-1-methyl-1H-indol-3-yl)-3-(3-methoxyphenyl)-4, 5-dihydro-1H-pyrazole-1-carboxamide, is a potential tubulin inhibitor exhibiting good anticancer activity. In our study, we illustrated the biological activities in HepG2 cells and the pharmacodynamic and pharmacokinetic profiles were evaluated in murine H22 hepatoma-bearing mice. Molecular docking assay and colchicine competition assay indicated that YMR-65 could bind tightly to the colchicine binding site of tubulin.

Co-delivery of docetaxel and palmitoyl ascorbate by liposome for enhanced synergistic antitumor efficacy.

Palmitoyl ascorbate (PA) as an antioxidant has the potential for the treatment of cancer. In the present study, a nanocarrier system was developed for co-delivery of docetaxel (DOC) with palmitoyl ascorbate and the therapeutic efficacy of a combination drug regimen was investigated. For this purpose, different ratios of docetaxel and palmitoyl ascorbate were co-encapsulated in a liposome and they all showed high encapsulation efficiency.

Pharmacokinetic effects of curcumin on docetaxel mediated by OATP1B1, OATP1B3 and CYP450s.

Curcumin can synergistically enhance docetaxel's in vitro and in vivo antitumor activity and has been co-administrated with docetaxel in clinical trials. The aim of our study is to investigate the effect of curcumin on the pharmacokinetics of docetaxel and explore its mechanism on OATP1B1, OATP1B3 and human liver microsomes (HLMs). In rats, curcumin increased the docetaxel area under the plasma concentration-time curve (AUC0-8h) and the terminal half-life (t1/2) to 1.

Enantioselective HPLC determination of oxiracetam enantiomers and application to a pharmacokinetic study in beagle dogs.

An enantioselective high-performance liquid chromatography method was developed and validated for the determination of oxiracetam enantiomers, a cognition and memory enhancer, in beagle dog plasma. The plasma samples were prepared by methanol extraction from 200μL plasma, and then the baseline resolution was achieved on a Chiralpak ID column (250mm×4.6mm, 5μm) with mobile phase of hexane-ethanol-trifluoroacetic acid (78:22:0.

Comparative pharmacokinetic studies of racemic oxiracetam and its pure enantiomers after oral administration in rats by a stereoselective HPLC method.

Oxiracetam (ORC), a nootropic drug used for improving the cognition and memory, has an asymmetric carbon in its structure and exists as (S)- and (R)-ORC. The pharmacokinetic profiles of racemic oxiracetam and its pure enantiomers in rats were evaluated and compared by enantioselective high-performance liquid chromatography, which was performed on a Chiralpak ID column with a mobile phase of hexane-ethanol-trifluoroacetic acid (78:22:0.1, v/v/v).

Investigation of the role of organic cation transporter 2 (OCT2) in the renal transport of guanfacine, a selective α2A-adrenoreceptor agonist.

1. Guanfacine is a selective α2A-adrenoreceptor agonist primarily excreted as its unchanged form through urine in human. This study was to investigate the involvement of organic cation transporter 2 (OCT2) in the renal tubular secretion of guanfacine.

Pharmacokinetics, tissue distribution, excretion and plasma protein binding studies of wogonin in rats.

Wogonin is a natural anticancer candidate. The purpose of this study was to explore the pharmacokinetic profiles, tissue distribution, excretion and plasma protein binding of wogonin in Sprague-Dawley rats. A rapid, sensitive, and specific LC-MS/MS method has been developed for the determination of wogonin in different rat biological samples.
