Nanoformulations derived from fine porous ZnO quantum dot nanoparticles (QD NPs) can offer strong potential medical applications; especially in cancer therapy. ZnO QD NPs was synthesized by sol-gel hydrothermal process, fast cold quenching and further smart surface functionalization methods to obtain ultrasmall size (1-4 nm) NPs. ZnO nanopolymer, a wetting agent, PEG co-solvent and water/oil emulsion stabilizer were considered in our nanofluid formulation. The resulting nanofluid was characterized by SEM, FTIR, photoluminescence, band gap energy, zeta potential and UV-Vis spectroscopy. The cytotoxic effects on the growth of four cancer cell lines were evaluated by MTT assay. The IC (µg/ml) values of 30, 41, 40 and 35 for KB44, MCF-7, HT29 and HeLa cells, respectively, after 48 h of nanoformulation treatment suggested the cytotoxic effect of this nanoformulation on these cell lines in a concentration-dependent manner (p < .05). ZnO nanofluid destroyed cancer cell lines more efficiently than the normal HFF-2 (IC= 105 µg/ml). The reduction in cell viability in response to ZnO nanofluid treatment induced apoptosis in the cultured cells. Skin sensitization test plus antibacterial activity were also measured. Side effect tests on 70 white mice in vivo resulted in only 3-4 abnormal situations in hepatic tissue section possibly due to the idiosyncratic drug reactions.

Background: This study was conducted to measure the antifungal activity of the extracts of 10 plant species used in traditional Iranian medicine against human pathogenic dermatophytes. Materials and Methods: In this experimental study, the leaves of these plants (Calendula officinalis, Acacia arabica, Altheae officinalis, Ginkgo biloba, Juglans regia, Osimum basilicum, Solanum nigrum, Hypericum perforatum, Urtica dioica, and Anagalis arvensis) were taken and extractions were made in methanol and were tested against Microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes, Trichophyton rubrum, Trichophyton schoenleinii, and Epidermophyton floccosum. The minimum inhibitory concentration (MIC) was determined using broth macrodilution method. The effects of plants extracts were compared with those of griseofulvin. Results: Plants under review showed antifungal activity against all the dermatophytes tested with MIC values ranging from 0.001 to 0.016 mg/mL using inhibitory zone estimation, 0.3 to 12.8 mg/mL using agar dilution method and 0.2 to 12.5 mg/mL using broth dilution method. The minimum fungicidal concentration (MFC) of the extracts ranged from 0.8 to 15.62 mg/mL. Conclusions: The results obtained suggested that H. perforatum, A. arvensis, and A. arabica have anti-dermatophyte activity.

The in vitro antimicrobial activities of crude ethanol, methanol and water extracts of the stem bark of O. gratissimumwere investigated. The extracts exhibited

Nanopharmaceuticals containing quantum dot nanoparticles (Q-Dot NPs) for treating serious cancers such as breast cancer have made fantastic proposals. In this study, ZnO quantum dot NPs are formulated via ZnO@PVP nanopolymer as co-assistants coordinating with efficacious suitable wetting agents, PEG-binding compound, and W/O emulsifier for producing eco-friendly water-based nanodrug. Several characterization techniques containing SEM, TEM, FTIR, photoluminescence, zeta potential, and UV-Vis absorption were employed for ZnO Q-Dot NPs in nanodrug. This work aims to investigate the anti-tumor effects of such nanomedicine on the 4T1 breast cancer cell line in BALB/c mice, being elaborated through intraperitoneal, injection (IVP) and oral therapy. The impressive findings showed that ZnO nanodrug caused changes in blood factors, having the most effectiveness at 40 µg/ml concentration after two weeks of oral treatments. The significant increase in white blood cells (WBC) neutrophils and meaningful decreases in lymphocytes and especially cholesterol were powerful simultaneous impacts, successfully treating malignant breast cancer masses. In this significant animal model research for breast cancer, the sick mice recovered entirely and even had a safe space to mate. Histopathological results showed no evidence of breast tumor How to cite this paper:
