conclusions large-scale studies on the healthy black african population could assess the relationship between diastolic dyssynchrony and changes in myocardial performance related to racial differences. results the frequency of some dyssynchrony markers was similar to that of other studies. the difference between maximal time-to-peak systolic velocity and minimal time-to-peak systolic velocity w...

the ionization effects of charged particles produced in neutron interactions for boron neutroncapture therapy are considered here using srim monte carlo code. the estimated values of these effects ina plexiglas acrylic phantom are shown to agree well with the available experimental values in high boronconcentration areas. as expected, the ionization effects from lithium and alpha particles are ...

Aging is characterized by loss of homeostasis across multiple tissues. The nervous system governs whole-body homeostasis by communicating external and internal signals to peripheral tissues. Here, we highlight neuronal mechanisms and downstream outputs that regulate aging and longevity. Targeting these neuronal pathways may be a novel strategy to promote healthy aging. To view this SnapShot, op...

the aim of this study was to detect the glutathione s-transferase(gst) enzyme activity of healthy / cystic liver as a diagnostic biomarker for hydatidosis. in order to compare with liver tissue, the level of the gsts enzyme activity of parasite was also determined.parasites were collected from sheep liver tissue with hydatid cysts at a local abattoir and washed with pbs buffer. collected parasi...

background: irreversible electroporation (ire) is a novel tumor ablation technique. ire is associated with high electrical fields and is often reported in conjunction with thermal damage caused by joule heating. for good response to surgery it is crucial to produce minimum thermal damage in both tumoral and healthy tissues named non-thermal irreversible electroporation(ntire). non-thermal irrev...
