Inhalant toxicants are postulated to contribute to the pathogenesis of chronic rhinosinusitis. Permethrin is a pesticide widely used in agricultural, industrial, and residential settings. The objective of this pilot study is to investigate the in vitro effects of permethrin on sinonasal epithelial cells (SNECs). Sinus mucosa was collected from 4 patients undergoing transsphenoidal pituitary surgery without a history of chronic rhinosinusitis. Cultured SNECs were exposed to varied concentrations of permethrin (0-156 µM) for 6 days. Cell viability and proliferation were determined via the MTT colorimetric assay and the Incucyte Live Cell Imaging System. Cellular reactive oxygen species (ROS) activity was measured by the DCFDA ROS detection assay. A statistically significant reduction in cell viability and proliferation was observed between the exposure and control groups at certain concentrations, and a dose-dependent increase in ROS activity was also observed. These findings indicate that permethrin may have deleterious effects on SNECs in a dose-dependent manner.

In this study, a novel inhibitor of ERCC1/XPF heterodimerization, A4, was used as an inhibitor of repair for DNA damage by platinum-based chemotherapeutics. Nano-formulations of A4 were developed, using self-assembly of the following block copolymers: methoxy-poly(ethylene oxide)-block-poly(α-benzyl carboxylate-ε-caprolactone) (PEO-b-PBCL), methoxy-poly(ethylene oxide)-block-poly(ε-caprolactone) (PEO-b-PCL), or methoxy-poly(ethylene oxide)-block-poly (D, L, lactide) (PEO-b-PDLA 50-50). The nano-formulations were characterized for their average diameter, polydispersity, morphology, A4 encapsulation and in vitro release.

Plant-associated microbiome plays important role in maintaining overall health of the host plant. Xanthium strumarium displaying resilience to various environmental fluctuations may harbor some bacterial isolates which can help this plant to grow worldwide. The present study aims to isolate endophytic and rhizospheric bacteria from X.

Ginkgolide B (GB) is a bioactive constituent found in Ginkgo biloba leaves that has been long recognized as a protective agent against many neurological disorders. Our study aimed to examine the effect of GB in an in vitro Parkinson's disease (PD) model and to investigate its neuroprotective mechanism as a primary objective. SK-N-SH cells were challenged with 1-methyl-4-phenylpyridinium (MPP) to act as a PD-like model of neuronal damage.

Background: Breast carcinoma stands out as the most widespread invasive cancer and the top contributor to cancer-related mortality in women. Nanoparticles have emerged as promising tools in cancer detection, diagnosis, and prevention. In this study, the antitumor and apoptotic capability of silver nanoparticles synthesized through Scrophularia striata extract (AgNPs-SSE) was investigated toward breast cancer cells.
