In this study, zinc oxide nanoparticles were synthesized through a simple co-precipitation method starting from acetate dihydrate and sodium hydroxide as reactants. The as-obtained ZnO morphologically structurally characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), photocatalytic activity, determining the antimicrobial activity against Gram-negative Gram-positive bacteria. XRD pattern of showed...
As it is used in all aspects of human life, water has become more and polluted. For the past few decades, researchers scientists have focused on developing innovative composite adsorbent membranes for purification. The purpose this research was to synthesize a novel membrane removal toxic pollutants (namely heavy metals, antibiotics microorganisms). as-synthesized chitosan/TiO2 were successfully prepared through simple casting method. TiO2 nanoparticle concentration from kept low, at 1% 5%,...
This paper evaluated the chemical and biological properties of bee pollen samples from Romania. Firstly, alcoholic extracts (BPEs) were obtained raw harvested by Apis mellifera carpatica bees. The composition BPE was determination total phenol content flavonoid content, UHPLC-DAD-ESI/MS analysis phenolic compounds, GC-MS fatty acids, esters, terpenes. Additionally, antioxidant activity Trolox Equivalent Antioxidant Capacity method. Furthermore, (antimicrobial cytotoxic activity). BP studied...
Bee bread has received attention due to its high nutritional value, especially phenolic composition, which enhances life quality. The present study aimed evaluate the chemical and antimicrobial properties of bee (BB) samples from Romania. Initially, alcoholic extracts (BBEs) were obtained BB collected prepared by Apis mellifera carpatica bees. composition BBE was characterized Fourier Transform Infrared Spectroscopy (FTIR) total phenols flavonoid contents determined.

The gut microbiota dysbiosis that often occurs in cancer therapy requires more efficient treatment options to be developed. In this concern, the present research approach is develop drug delivery systems based on magnetite nanoparticles (MNPs) as nanocarriers for bioactive compounds. First, MNPs were synthesized through spraying-assisted coprecipitation method, followed by loading bee pollen or bread extracts and an antitumoral (5-fluorouracil/5-FU). loaded-MNPs morphologically structurally...
By the developmentof new antineoplastic drugs addressed tospecific sites (key to tumor growth), targeted agents, which do not interfere with most normal cells have many advantages like fewer side effects (as personalized treatment), and prolonged survival time of cancer patients compared conventional therapy. As current approaches in therapy, drug delivery systems based on polymers (synthetic, natural or combinations micelles, nanospheres, nanocapsules, nanogels, polymer-drug conjugates,...
