Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...

Complex structural effects in the nuclide production from the projectile fragmentation of 1 A GeV U nuclei in a titanium target are reported. The structure seems to be insensitive to the excitation energy induced in the reaction. This is in contrast to the prominent structural features found in nuclear fission and in transfer reactions, which gradually disappear with increasing excitation energ...

We show that the interplay between the Coulomb interaction and the strong interaction, which is enhanced in the nuclear surface, leads to a significant upward shift of the proton single–particle levels. This shift affects the position of the calculated proton drip line, a shift towards decreasing Z by several units. The same mechanism is responsible for significant corrections to the mass diffe...

Density-functional-based and ab initio calculations were implemented at different computational levels to estimate the binding energy of Zn2+ ion adsorbed on the available sites of a silicate MEL-type adsorbent. B3LYP and MP2 were used in combination with the 6-31G*, 6-31+G*, LanL2DZ, 6-311+G*, and Def2-TZVP basis sets. The zinc cation was found to preferentially occupy the 6MR sites followed b...

Nuclear Medicine was established in Myanmar in 1963 by Dr Soe Myint and International Atomic Energy expert Dr R. Hochel at Yangon General Hospital. Nuclear medicine diagnostic and therapeutic services started with Probe Scintillation Detector Systems and rectilinear scanner. In the early stage, many Nuclear Medicine specialists from the International Atomic Energy Agency (IAEA) spent some time ...

We study charmonia in electromagnetic and rotational fields the frame of a potential model. Different from temperature field which is isotropic leads to well-known charmonium dissociation, break down radial symmetry, competition between strong interaction direction Lorentz force makes transit an bound state with positive binding energy anisotropic negative energy. The transition seems possible ...

Background: The earlier Atomic Bomb explosion in Hiroshima and Nagasaki, and three worth mentioning nuclear accidents - detonation at Fukushima Daiichi nuclear plant, Chernobyl nuclear fallout and an accident at Three Mile Island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. The central focus of this paper is to review radiation-mediated health e...
