Anti-Inflammatory and Antioxidant Effects of Rosmarinic Acid Trimetallic (CuZnFeO) Nanoparticles.

Newly, green metallic-nanoparticles (NPs) have received scientists' interest due to their wide variable medicinal applications owned to their economical synthesis and biologically compatible nature. In this study, we used rosmarinic acid (RosA) to prepare CuZnFeO NPs and later encapsulated them using PEG polymer. Characterization of NPs was done using the XRD method and SEM imaging.

Comparative anti-proliferative effects of potential HER2 inhibitors on a panel of breast cancer cell lines.

Background: Breast cancer is one of the most lethal types of cancer in women worldwide. The human epidermal growth factor receptor 2 (HER2) is considered as a validated target in breast cancer therapy. Previously, we have used quantitative structure activity relationship QSAR equations and their associated pharmacophore models to screen for new promising HER2 structurally diverse inhibitory leads which were tested against HER2-overexpressing SKOV3 ovarian cancer cell line.

Effect of light-emitting diodes, platelet-rich plasma, and their combination on the activity of sheep tenocytes.

Healthy tendons play an important role in joint movements and subjected to a group of pathologies called tendinopathy due to multiple factors. Tendons have a slowly repairing process due to the low vascularity and cellularity. Treatment options aimed at potentiating the healing response and relieving symptoms.

Culturing conditions highly affect DNA methylation and gene expression levels in MCF7 breast cancer cell line.

The levels of DNA methylation and their role in gene expression are key factors that could affect diagnosis, prognosis, and treatment options of different diseases. In this study, the methylation levels of 22 genes that are mostly correlated to breast cancer were determined using EpiTect methyl II PCR array. This analysis was performed to determine the effect of cells' passage number and the use of antibiotics in the culturing media on gene methylation levels in MCF7 cell line.

Discovery of new human epidermal growth factor receptor-2 (HER2) inhibitors for potential use as anticancer agents via ligand-based pharmacophore modeling.

To discover potential antitumor agents directed toward human epidermal growth factor receptor-2HER2/ErbB2 overexpression in cancer, we have explored the pharmacophoric space of 115 HER2/ErbB2 inhibitors. This identified 240 pharmacophores which were subsequently clustered into 20 groups and cluster centers were used as 3D-pharmacophoric descriptors in QSAR analysis with 2D-physicochemical descriptors to select the optimal combination. We were obliged to use ligand efficiency as the response variable because the logarithmic transformation of bioactivities failed to access self-consistent QSAR models.
