This research presents the results of the effect of different concentrations (2, 4, 6, and 8 wt %) of multiwall carbon nanotubes (MWCNTs) and aluminum oxide nanoparticles (AlO) on the characteristics of lithium-calcium grease (LCG). The LCG/AlO and LCG/MWCNT were studied and illustrated by measuring the dropping point, consistency, thermal conductivity, and tribological characteristics of nanograins (wear, friction, and welding point) by using a four-ball tribometer. The morphologies of the additives and the nanogrease were examined and evaluated by X-ray diffraction and transmission electron microscopy.

<b>Background and Objective:</b> Despite advancements in modern therapeutic strategies, breast cancer still the most common cause of the high death rate among women worldwide. Wild plants and their extracts have been used in traditional medicine because of their efficient anti-cancer properties. This study aims to investigate <i>in vitro</i> the anti-cancer, anti-proliferative and potential therapeutic effects of <i>Convolvulus spicatus </i>(<i>C.

Evidence suggests that Metformin (Met) may have a therapeutic and protective effect against both DM and HCC. Therefore, the aim of this study was to evaluate the antioxidant effect of Met against DM and HCC-induced oxidative stress in rat model.

The present study was designed to examine the heptoprotective effect of ketoconazole in both in vitro and in vivo liver injury models. Hepatocyte injury was induced by 8mM CCl4 while hepatic fibrosis model was established by injecting 1 ml/kg CCl4 followed by treatment with ketoconazole.
