Determination of Elements in Gymnema inodorum Lour by Particle Induced X-Ray Emission (PIXE).

At present, Thailand uses medicinal plants to treat various diseases. Alternative medicine utilizes Gymnema inodorum Lour for antipyretic and anti-allergic purposes. There are also other research studies to treat diabetes mellitus, coronary artery disease, cataract, rheumatoid arthritis, gout, liver cancer, and stomach cancer.

Low-Energy Ion-Species-Dependent Induction of DNA Double-Strand Breaks: Ion Energy and Fluence Thresholds.

The goal of this study was to determine the critical ion-radiation conditions under which heavy ion beams can induce DNA double-strand breaks. Helium, nitrogen and argon-ion beams in the energy range of 20 eV to 2 keV were used to irradiate naked DNA plasmid pGFP to fluences of 1, 2 and 4 × 10 ions/cm. The topological forms of DNA were subsequently analyzed using gel electrophoresis.
