Objective: To evaluate the in vitro antioxidant power of cactus pear seed oil [Opuntia ficusincida L. MILL.(CPSO)] and its protective effect against chemically induced diabetes mellitus in mice. Methods: The in vitro antioxidant effect of CPSO was evaluated using 2,2-diphenyl-1-picrylhydrazyl(DPPH) scavenging assay. The preventive effect was conducted on Swiss albino mice treated with CPSO(2 m L/kg, per os), before and after a single intraperitoneal alloxan administration(100 mg/kg). Survival rate, body weight and fasting blood glucose were measured and histopathological analysis of pancreas was performed to evaluate alloxaninduced tissue injuries. Results: CPSO exhibited an antioxidant effect in DPPH scavenging assay. Moreover, the administration of CPSO(2 m L/kg) significantly attenuated alloxaninduced death and hyperglycemia(P<0.001) in treated mice. Morphometric study of pancreas revealed that CPSO significantly protected islets of langerhans against alloxan induced-tissue alterations. Conclusions: Based on theses results, CPSO can prevent alloxan-induced-diabetes by quenching free radicals produced by alloxan and inhibiting tissue injuries in pancreatic β-cells.

We have systematically analysed the dynamic moments of inertia of the experimental superdeformed (SD) bands observed in the A = 190, 150 and 60-80 mass regions as functions of rotational frequency. By combining the different mass regions, the dramatic features of the dynamic moments of inertia were found and explained based on the calculations of the pairing fields of SD nuclei with the anisotropic harmonic oscillator quadrupole pairing Hartree-Fock-Bogoliubov model

Platinum and gold have the similar crystal structure but different electronic affinities, as well as different effective electron densities near the implanted ions. Both the differences favour larger decay rate of 7Be in Pd than that in Au. We measured the variation of the decay rate of 7Be implanted in Pd and Au host materials. We have found that the decay rate of 7Be in Pd is larger than that in Au by 0.8%.

The root-mean-square (rms) radii of the last nucleons in the 2s1/2 states of ^21Ne, ^21Na, ^17O and ^17F are found to be 4.4±0.5, 5.2±0.6, 4.3±0.5 and 5.0±0.6 fm, respectively, from transfer reaction data. The results show that the 2s1/2 states of ^21Na and ^17F are proton halo states, while the analogous states in their mirror nuclei ^21Ne and ^17O can be considered as neutron skin states. Comparisons among the rms radii of these states lead us to expect that a neutron halo nucleus has a proton halo mirror partner, and the Coulomb barrier is a determinant factor limiting the extension of the rms radius of the loosely bound proton.

Phase diagrams and magnetic properties of the mixed spin-1 and spin-3/2 Ising film with different single-ion anisotropies are investigated, by the use of Monte Carlo simulation based on heat bath algorithms. The effects of the crystal-fields and the surface coupling on the phase diagrams are investigated in detail and the obtained phase diagrams are presented. Depending on the Hamiltonian parameters, the system exhibits both second-and first-order phase transitions besides tricritical point, triple point, and isolated critical end point.
