The therapeutic role of naringenin nanoparticles on hepatocellular carcinoma.
BMC Pharmacol Toxicol
January 2025
Biochemistry Department, Faculty of Science, Tanta University, Tanta, Egypt.
Background: Naringenin, a flavonoid compound found in citrus fruits, possesses valuable anticancer properties. However, its potential application in cancer treatment is limited by poor bioavailability and pharmacokinetics at tumor sites. To address this, Naringenin nanoparticles (NARNPs) were prepared using the emulsion diffusion technique and their anticancer effects were investigated in HepG2 cells.

Need For A Strategic Approach To Knowledge Transfer And Exchange: Late-phase clinical trials and systematic reviews find results that have the potential to improve health outcomes for people. However, there are often delays in these results influencing clinical practice. We developed a knowledge transfer and exchange strategy to support research teams, aiming to identify activities along the research process to maximise and accelerate the research impact.

Background: Tyrosine kinase inhibitors (TKIs) improve prognosis in chronic myeloid leukemia (CML). Nilotinib and ponatinib, second- and third-generation TKIs, respectively, have been reported to cause adverse vascular occlusive events such as myocardial infarction and peripheral arterial disease. However, little is known about the risk of cerebral infarction associated with severe cerebrovascular stenosis, which is a late complication of TKIs.

Among the known aromatic -heterocycles, pyrroles are significant and versatile privileged components in pharmacologically relevant molecules. Herein, we demonstrate a protocol for the selective construction of alkynylated pyrroles in a diversity-oriented fashion through divergent C2/C5 site-selective alkynylation of pyrrole derivatives by employing a palladium catalyst with two different solvent systems. In the presence of 1,4-dioxane, the C2-alkynylation process via chelation-assisted palladation is favored.

A mounting number of studies have been documenting strong pro-inflammatory and pro-fibrotic effects of carbon nanotube (CNT). However, the molecular mechanisms of single-walled CNT (SWCNT)-provoked lung injury remain to be elucidated. Here, we established a mice model of SWCNT-induced lung injury by intratracheal instillation and found that C5a-C5a receptor-1 (C5aR1) signaling was significantly activated along with abundant neutrophils recruitment in lungs at early phase post SWCNT administration, which were positively correlated with early lung inflammation and late pulmonary fibrosis.
