Essential oils of some medicinal plants and their biological activities: a mini reviewAbstract Medicinal herbs have an essential function in health and therapy. Bioactives of medicinal plants showed fewer side effects than manufactured drugs and their antioxidant properties are responsible for their different therapeutic properties. Essential oils (EOs) are an aromatic mixture of active components with a strong aroma obtained from aromatic plants. Na... ...

Review on synthesis of novel carbonyl derivatives of biological macromolecules by oxidation of polysaccharides with permanganate ion in alkaline media Abstract Synthesis of mono- and diketones as carbonyl group derivatives in biomacromolecular chemistry is very essential task for industrial biotechnology applications. However, there are various techniques to synthesize such carbonyl groups, the most common and efficient methods are the chemical oxidation of alcoholic biological macromolecule by suitable oxidizing ... ...
Upper Paleocene–lower Eocene calcareous nannofossil biostratigraphy at Nukhul, West Central Sinai, Egypt Abstract This research offers a comprehensive examination of calcareous nannofossils, isotopic ratios (δ18 O and δ13 C), and carbonate content spanning the critical Paleocene-Eocene transition at Gebel Nukhul. The study covers three lithostratigraphic formations: Tarawan, Esna, and Thebes. By meticulous analysis, we’ve identif... ...
Characterization and identification of Lactobacillus rhamnosus and Enterococcus durans as probiotic potential isolated from selected dairy products in EgyptAbstract Probiotics are living microbes that promote consumer health when taken in significant quantities with food. The aim of this research was identifying the probiotic properties (in vitro) of lactic acid bacteria (LAB) isolated from traditional fermented dairy products from Egypt (Kareish cheese, Rayeb milk, local yoghurt and buttermilk). Only 13 isolates were ... ...
