  • Nanoformulated rosemary extract impact on oral cancer: in vitro study

    • Authors: Ellithy, Marwa Mohamed;  Advisor: -;  Participants: Aly, Riham Mohamed; Tarek, Heba El-Sayed (2022)

  • Rosemary nanoparticles composite characterization Transmission electron microscope (TEM) informed us on the particle shape as well as their size. TEM micrographs of these nanoparticles are shown in Fig. 1. Electron microscopy analysis confirmed the presence of nanoparticles. RE-loaded chitosan nanoparticles were found to be spherical, distinct and regular with a size of 0.5 µm to 200 nm. Their surface is solid and has a dense structure. Chitosan nanoparticles appeared aggregated in the photomicrographs. The RE particles were well coated by chitosan. The particle size of the prepared nanoparticles ranged from 0.5 µm to 200 nm with an average size of 100 nm.

  • Nutraceutical with a promising oral anticancer effect: in vitro study on apricot oil extract

    • Authors: Ellithy, Marwa Mohamed;  Advisor: -;  Participants: Tarek, Heba Elsayed; Shalash, Heba Nader (2023)

  • One of the major threats to human health is malignancy. Treatment regimens usually followed by either chemo or radiotherapy have a wide range of collateral unwanted side effects. Scientists seek alternatives with less or no adverse consequences. Nutraceuticals possess disease-modifying implications in medicine related to Alzheimer’s, cardiovascular, Parkinson’s diseases and malignancy. Apricot oil extract is one such nutraceutical. Its active component is amygdalin, known also as vitamin B.17 or laetrile. It is found in a wide range of vegetable species. Amygdalin is found in high concentration in the kernels of rosaceous fruits such as bitter nuts and apricot kernels. Amygdalin is an...
