Laparoscopic versus open lumbar sympathectomy in critical limb threatening ischemia patients in Egypt

Autor: Wael E. Shaalan, Ali A. Elemam, Hassan Lotfy, Ahmad R. Naga, Mohamed I. Mohamed, Yomna E. Dean, Tamer N. Abdelbaki

Publikováno v: BMC Surgery, Vol 24, Iss 1, Pp 1-10 (2024)

Abstract Purpose The treatment of critical limb-threatening ischemia (CLTI) is revascularization. Lumbar sympathectomy (LS) could be attempted when this is not amenable. Using laparoscopic techniques to perform LS adds the advantages of minimally inv

Microwave-Assisted, Preparation, Characterization, and Biological Activities of Schiff Bases Derived from 4-Aminoantipyrine with Acetonyl Acetone for Some New Rare-Earth Metals

Autor: Kawther Adeeb Hussein, Naser Shaalan, Marwa Faeq

Publikováno v: Indonesian Journal of Chemistry, Vol 24, Iss 5, Pp 1470-1480 (2024)

Five new lanthanide complexes based on azomethine (Schiff bases) ligands have been synthesized, including La, Nd, Er, Gd, and Dy. Complexes were synthesized using the azomethine Schiff bases resulting from condensation reactions between 4-aminoantipy

The effect of three urease inhibitors on H. pylori viability, urease activity and urease gene expression

Autor: Hanaa Shaalan, Maya Azrad, Avi Peretz

Publikováno v: Frontiers in Microbiology, Vol 15 (2024)

BackgroundTreatment of Helicobacter pylori (H. pylori) infections is challenged by antibiotic resistance. The urease enzyme contributes to H. pylori colonization in the gastric acidic environment by producing a neutral microenvironment. We hypothesiz
