Background: Deltamethrin (DTM) is a pyrethroid derivative, which is the most potent products of Type 2 insecticides and acts by delaying the closure of sodium channels. Estrogen as a vascular growth factor on ovarian tissue plays an essential impact further to its involvement in follicular growth. On the other hand, the role of angiogenesis on ovarian tissue in inhibiting the apoptotic provoker...

iran is located in an area with high earthquake risk. there are over 20 active faults with length of 500 km and also densely populated parts of the country have been rendered vulnerable to strong earthquakes. however, existence of eight faults of the main faults of iran along with at least 18 faults with length of more than 100 km in kerman province have turned the place into one of the riskies...

With advanced composites increasing replacing traditional metallic materials, the material inhomogeneity and inherent anisotropy of such materials lead to not only new attributes for aerospace structures, but also introduce new technology to damage tolerant design and analysis. The deleterious effects of changes in material properties and initiation and growth of structural damage must be addre...

background hypotension during spinal anesthesia is common and can lead to severe injuries and even death. administration of crystalloid fluids is advised to prevent occurrence of hypotension; however its effectiveness is still the matter of arguments. objectives this study was designed to compare the effects of ringer`s lactate and hydroxyethyl starch 6% on hemodynamic parameters after spinal a...

Peripheral neuropathy is a severe dose limiting toxicity associated with cancer chemotherapy. Ever since it was identified, the clear pathological mechanisms underlying chemotherapy induced peripheral neuropathy (CIPN) remain sparse and considerable involvement of oxidative stress and neuroinflammation has been realized recently. Despite the empirical use of antioxidants in the therapy of CIPN,...

To date, mapping of femoral head damage on a global implant level has been limited to representation by standard surface roughness parameters, usually the average roughness, Ra. Attempts to relate average regional roughness parameters to clinical wear rates however, have proven difficult [1]. Average surface roughness alone fails to suitably describe scratch damage as observed in retrievals, be...
