Objective(s): Aluminum phosphide (AlP) is commonly used pesticide which could cause poisoning mainly through the induction of oxidative stress. The present study aimed to evaluate the effects of nano-curcumin and curcumin on the oxidant and antioxidant system in the liver mitochondria using AIP-induced toxicity model.Materials and Methods: In this study, 36 male albino Wistar rats were ra...

In order to intelligently diagnose the vibration types corresponding to various errors in nano-imaging process, so that the experimental personnel could take corresponding measures, in this paper, firstly, all types of vibration signals were decomposed and reconstructed in nano-imaging process based on the wavelet transform, thus extracting feature vectors of all types of vibration signals. Sec...

Discovering the mechanical properties of biological composite structures at the Nano-scale is much interesting today. Top Neck mollusk shells are amongst biomaterials Nano-Composite that their layered structures are composed of organic and inorganic materials. Since the Nano indentation process is known as an efficient method to determine mechanical properties like elastic modulus and hardness ...

background sinusitis is one of the most prevalent infectious diseases among those who visit doctor, which requires antibiotic intervention. the most common types of bacteria causing this disease are streptococcus pneumonia, streptococcus pyogenes, staphylococcus aureus and pseudomonas aeroginosa. nonetheless due to dangerous side effects of chemical drugs on body and increased drug resistance o...
