Bone marrow mesenchymal stem cells (BM-MSC) have recently been predicted to have a major therapeutic potential due to secretion of soluble factors and the release of cytokines and growth factors, which could mediate the cellular communication to induce cell differentiation/maturity. The aim of the present study was to determine the effect of mBM condition medium on morphine-induced cell death in PC12, U87, AGS and MCF-7 cell lines. The condition media were harvested as mBM soup (mBM soup 24 and mBM soup 48h, respectively). ⋯ Viability assay showed that mBM soup (24 and 48 h) in time-dependent manner increased cell viability (pndings suggest that mBM soup can enhance the proliferation and growth of cell lines and can suppress cell death induced by morphine (Fig. 8, Ref. 59).

Drug repurposing studies enable shorter routes to the clinic by skipping the steps like in vitro in vivo screening, chemical optimization and toxicological studies. In our study, we investigated the potent anti-cancer effect of Alzheimer's drug Memantine on 4T1 breast cancer cells. ⋯ Memantine inhibited 4T1 breast cancer cell proliferation at significantly lower doses than mostly studied re-purposed drug Metformin. Therefore, we believe that memantine might hold a great promise as a new repositioned drug in cancer treatment and it is our further interest to investigate its effects in vivo (Fig. 3, Ref. 22).

The study was designed to evaluate the possible adverse effects and consequences of metal oxide nanoparticles used on some major body organ functions and health parameters. ⋯ The present study confirmed the health risks of the use of metal oxide nanoparticles in the medical field without precautions and supervision; and may encourage application of nanoparticles from alternative origins, such as plants, algae, or microorganisms instead (Tab. 5, Fig. 4, Ref. 30) Keywords: nanoparticles, thyroid, parathyroid, kidney, oxidative stress, blood, green, alternative.

The present study investigated the role of redox balance, inflammation, mitochondrial dysfunction, and apoptosis in Tramadol (Tra)-induced testicular toxicity. ⋯ The present results suggest that Tra exposure may lead to reproductive toxicity due to the loss of the antioxidant defence system, mitochondrial dysfunction, and activation of inflammatory and apoptotic pathways (Tab. 4, Fig. 5, Ref. 63).
