To highlight the importance of small earthquakes in seismic hazard, a study of the 11 may 2016, mw 4.9, Tesistan, mexico earthquake is presented. Due to the close proximity of the event to the city, accelerations were considerably higher than those caused by historical severe earthquakes (6.0 mw is paper addresses two objectives related to the Tesistan event: the fi rst is to estimate the focal mechanism solution in order to place the event in the context of the tectonic environment of this area. The second is focused on a vulnerability evaluation of buildings that suff ered resonance. Several building′s typologies with variations in construction system and height are assessed in terms of resonance with the structural and soil periods. The results show that around the Zapopan station, strong damage is expected in intermediate to high-rise buildings (12-30 m) with moment resistant frame systems and in reinforced concrete shear walls. masonry structures around this station may not present resonance. in contrast, in the surroundings of the Guadalajara station, all intermediate height buildings from 9 to 21 m may present resonance.

Reviewed are the present status and future prospects of the laser fusionresearch at the iLE Osaka. The Gekko Xii and Peta Watt laser system have been operated forinvestigating the implosion hydrodynamics, fast ignition, and the relativistic laser plasmainteractions and so on. in particular, the fast ignition experiments with cone shell target havebeen in progress as the UK and US-Japan collaboration programs. in the experiments, the implodedhigh density plasmas are heated by irradiating 500 J level peta-watt laser pulse. The thermalneutron yield is found to increase by three orders of magnitude by injecting the peta-watt laserinto the cone shell target. The Rayleigh-Taylor instability experiment results are also reviewed isthis paper.

The Fusability of Erythrocytes as a method for Evaluating the instability of Their membranes

引用

Open Journal of Biophysics 2013年第3期3卷 198-200页

作者： Yury A. Sheremet’ev Aleksandra n. Popovicheva methun m. Rogozin Gregory Y. Levin nizhny novgorod Scientific Research institute of Traumatology and Ortopedics Nizhny Novgorod Russia

A novel approach to the study of erythrocytes instability based on assessment fusability of their plasma membrane is presented. The fusability of erythrocytes normal blood, stored for 7 days at 4°C, and type 2 patients with diabetes were studied. Human erythrocytes were fused by incubation with La3+ at final concentrations from 50 to 200 μm. Erythrocytes aggregates were incubated at 37°C for 120 min. The fusability of erythrocytes was evaluated using a light microscope. it was shown that La3+ induced extensive fusion of erythrocytes after 7 days of blood storage and erythrocytes of patients with diabetes. incubation of normal erythrocytes at 37°C for 120 min does not induce cell fusion.

The inhibition of a-glucosidase and glucose-6-phosphatase,two enzymes involved in the carbohydrate metabolism,is an important target to control glycaemia on individuals with type 2 *** this work we report for the first time the inhibition of both enzymes by the antihyperglycemic n-butanol extract from Genista tenera(Fabaceae).This extract decreased a-glucosidase and glucose-6-phosphatase activities to 0.97 and 80.25%,respectively,being more effective than acarbose,and phlorizin,the positive controls,which reduced enzymes activities only to 17.39 and 96.06%.Once inflammation and oxidative stress are related to diabetic impairments,the anti-inflammatory activity of the extract was also evaluated,through its inhibitory activity over COX-1 enzyme(47.5%inhibition).moreover,after induction of oxidative stress by UV radiation,the viability of irradiated rat liver hepatoma cells exposed to the extract was significantly higher(67.82%)than that promoted by ascorbic acid,the positive control(45.05%).in addition,the stability of the extract under gastrointestinal conditions was evaluated by HPLC–Dad-ESi–mS/*** diglycosides were identified as the main constituents of the extract,and no alterations in the chemical composition nor in the antioxidant activity were observed after in vitro digestion with artificial gastric and pancreatic juices.
