Abstract
The main challenge of using nanoliposome systems is controlling their size and stability. In order to overcome this challenge, according to the research conducted at the Research Centre for New Technologies of Biological Engineering, University of Tehran, a model for predicting the size and stability of nanoliposome systems based on thermodynamic relations has been presented. In this model, by using the presented equations and without performing many experiments in the laboratory environment, the effect of temperature, ionic power and different pH can be considered simultaneously whereas examining the components of size, stability and any feature were considered before. Synthesis and application of liposomal nanocarriers in different operating conditions can be investigated and predicted, and due to the change in temperature and pH, the smallest size of th system can be obtained. In this study, we were able to model the synthesis and storage conditions of liposomal nanocarriers at different temperatures and acidic, neutral and alkaline pHs, based on the calculation of mathematical equations. This model also indicates that with increasing temperature, the radius increases but with increasing pH, the radius first increases and then decreases. Therefore, this model can be used to predict size and stability in different operating conditions. In fact, with this modelling method, there is no need to study through laboratory methods and analysis to determine the size, stability and surface loads, and in terms of Accuracy, time and cost savings are affordable.

Abstract
Therapeutic cancer drug efficacy can be limited by insufficient tumor penetration, rapid clearance, systemic toxicity and (acquired) drug resistance. The poor therapeutic index due to inefficient drug penetration and rapid drug clearance and toxicity can be improved by using a liposomal platform. Drug resistance for instance against pemetrexed, can be reduced by combination with docetaxel. Here, we developed a specific liposomal formulation to simultaneously deliver docetaxel and pemetrexed to enhance efficacy and safety. Hydrophobic docetaxel and hydrophilic pemetrexed were co-encapsulated into pH-sensitive liposomes using a thin-film hydration method with high efficiency. The physicochemical properties, toxicity, and immunological effects of liposomes were examined in vitro. Biodistribution, anti-tumor efficacy, and systemic immune response were evaluated in vivo in combination with PD-L1 immune checkpoint therapy using two murine colon cancer models. In cellular experiments, the liposomes exhibited strong cytotoxicity and induced immunogenic cell death. In vivo, the treatment with the liposome-based drug combination inhibited tumor development and stimulated immune responses. Liposomal encapsulation significantly reduced systemic toxicity compared to the delivery of the free drug. Tumor control was strongly enhanced when combined with anti-PDL1 immunotherapy in immunocompetent mice carrying syngeneic MC38 or CT26 colon tumors. We showed that treatment with liposome-mediated chemotherapy of docetaxel and pemetrexed combined with anti-PD-L1 immunotherapy is a promising strategy for the treatment of colon cancers.

Abstract
The simulated liposome models provide events in molecular biological science and cellular biology. These models may help to understand the cell membrane mechanisms, biological cell interactions, and drug delivery systems. In addition, the liposomes model may resolve specific issues such as membrane transports, ion channels, drug penetration in the membrane, vesicle formation, membrane fusion, and membrane protein function mechanism. One of the approaches to investigate the lipid membranes and the mechanism of their formation is by molecular dynamics (MD) simulations. In this study, we used the coarse-grained MD simulation approach and designed a liposome model system. To simulate the liposome model, we used phospholipids that are present in the structure of natural cell membranes (1,2-Dioleoyl-sn-glycero-3-phosphocholine (DOPC) and 1,2-Dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE)). Simulation conditions such as temperature, ions, water, lipid concentration were performed based on experimental conditions. Our results showed a liposome model (ellipse vesicle structure) during the 2100 ns was formed. Moreover, the analysis confirmed that the stretched and ellipse structure is the best structure that could be formed. The eukaryotic and even the bacterial cells have elliptical and flexible structures. Usually, an elliptical structure is more stable than other assembled structures. The results indicated the assembly of the lipids is directed through short-range interactions (electrostatic interactions and, van der Waals interactions). Total energy (Van der Waals and electrostatic interaction energy) confirmed the designed elliptical liposome structure has suitable stability at the end of the simulation process. Our findings confirmed that phospholipids DOPC and DOPE have a good tendency to form bilayer membranes (liposomal structure) based on their geometric shapes and chemical-physical properties. Finally, we expected the simulated liposomal structure as a simple model to be useful in understanding the function and structure of biological cell membranes. Furthermore, it is useful to design optimal, suitable, and biocompatible liposomes as potential drug carriers.

Effects of Hexachlorophene, a Chemical Accumulating in Adipose Tissue, on Mouse and Human Mesenchymal Stem Cells. Tissue Eng Regen Med 2018; 15:211-222.

Abstract
The hexachlorophene (HCP) is a highly lipophilic chlorinated bisphenol present in hygienic and dermatological products. The HCP accumulates preferentially in adipose tissue that is a privileged source of mesenchymal stem cells (MSCs). The evaluation of the potential effects of HCP on MSCs is important for their medical application. Here we examined the effects of HCP on murine adipose tissue-derived stem cells (ADSCs) and human umbilical cord-derived stem cells (UCSCs) in cell culture. We found that 10−4 and 10−5 M HCP inhibits proliferation, osteogenesis and increases apoptosis of ADSCs and UCSCs. While the effect of HCP on proliferation and differentiation potential of these two cell lines was similar, the UCSCs appeared much more resistant to HCP-induced apoptosis than ADSCs. These results suggest that the adipose tissue-derived ADSCs have higher sensitive for HCP than umbilical cord-derived UCSCs and indicate that the umbilical cord can be a preferable source of MSCs for prospective medical applications in the future.
