Fair Distribution of Medical Facilities is one of the most critical issues affecting economic and health indicators. Iranian Social Security Organization (ISSO) is a non-governmental organization responsible for providing medical services to insured individuals in 77 hospitals, 265 polyclinics, and clinics that has faced much demand from the insured to build a new medical center. So, Due to the significant role of ISSO in meeting the medical needs and its high coverage (almost 42%) in Iran, we aimed to identify the factors influencing medical facilities' fair distribution in the ISSO.

Introduction: Despite Iran's success in reducing neonatal mortality rate, it is still far behind some developing countries and some Asian countries. The aim of this study was to summarize the measures taken and proposed solutions to design a model to control neonatal mortality.

Methods: This applied cross-sectional analytical study was performed using a factor analysis method derived from 4 models of neonatal mortality reduction.

Photothermal therapy is one of the promising approaches toward cancer treatment. To date, several compounds have been developed for this application, among which nanoparticles are attracting ever-increasing attention. One of the obstacles in developing efficient photothermal nanoparticle agents is their off-target effect which is mainly mediated via non-specific interactions with proteins.

Multimodal cancer therapy has become a new trend in clinical oncology due to potential generation of synergistic therapeutic effects. Herein, we propose a multifunctional nanoplatform comprising alginate hydrogel co-loaded with cisplatin and gold nanoparticles (abbreviated as ACA) for triple combination of photothermal therapy, chemotherapy and radiotherapy (thermo-chemo-radio therapy). The therapeutic potential of ACA was assessed in combination with 532 nm laser and 6 MV X-ray against KB human mouth epidermal carcinoma cells.

Electroactive scaffolds derived from carbohydrate hydrogels were synthesized, resulting in a large shift in the conductivity of chitosan (CS) from 10 S/cm to about 10 S/cm, assigned to CS-oligoaniline. Several analyses including UV-vis spectroscopy and cyclic voltammetry were performed, before examining the carbohydrate-based scaffolds for their ability to recapitulate the neural tissue microenvironment. Good conductivity and resemblance of the modulus to soft tissue of the optimized hydrogels led to appropriate cellular activity and neural regeneration.

Developing a simple produces for efficient derivation of motor neurons (MNs) is essential for neural tissue engineering studies. Stem cells with high capacity for neural differentiation and scaffolds with the potential to promote motor neurons differentiation are promising candidates for neural tissue engineering. Recently, human olfactory ecto-mesenchymal stem cells (OE-MSCs), which are isolated easily from the olfactory mucosa, are considered a new hope for neuronal replacement due to their neural crest origin.

Photothermal therapy is achieving ever-increasing attention as a promising method for killing cancer cells. Although, gold nanoparticles are regarded as one of the most effective photothermal therapy agents, the mechanisms underlying their action have to be addressed. Moreover, studies have showed that gold nanoparticles induce apoptosis in treated cultures.

Regeneration and functional recovery after peripheral nerve damage still remain a significant clinical problem. In this study, alginate/chitosan (alg/chit) hydrogel was used for the transplantation of olfactory ectomesenchymal stem cells (OE-MSCs) to promote peripheral nerve regeneration. The OE-MSCs were isolated from olfactory mucosa biopsies and evaluated by different cell surface markers and differentiation capacity.

The generation of dopaminergic neurons from stem cells is a potential therapeutic approach to treat neurodegenerative disorders, such as Parkinson's disease. The current study aims to investigate the potential of two different types of mesenchymal stem cells derived from human Wharton's jelly and nasal cavity for differentiation into dopaminergic neurons. The differentiation capacities of both cell types were evaluated using real-time PCR, immunocytochemistry, flow cytometry and HPLC.

The production of dopaminergic (DA) neurons from stem cells holds a great promise for future clinical treatment of neurodegenerative diseases, such as Parkinson's disease (PD). Olfactory ecto-mesenchymal stem cells (OE-MSCs) derived from the adult human olfactory mucosa can be easily isolated and expanded in culture while maintaining their immense plasticity. In addition to reduced ethical concerns, OE-MSCs could be transplanted across allogeneic barriers, making them desirable stem cells for clinical applications.

To perform biological evaluations of newly-designed Pt(II) and Pd(II) complexes, the present study was conducted with targeted protein human serum albumin (HSA) and HCT116 cell line as model of human colorectal carcinoma. The binding of Pt(II) and Pd(II) complexes to HSA was analyzed using fluorescence spectroscopy and molecular docking. The thermal stability and alterations in the secondary structure of HSA in the presence of Pt(II) and Pd(II) complexes were investigated using the thermal denaturation method and circular dichroism (CD) spectroscopy.

In this study, gold coated iron oxide nanoparticle (Au@FeO NP) was synthesized in a core-shell structure. Photothermal and radiosensitization effects of Au@FeO NPs were investigated on KB human mouth epidermal carcinoma cell line. Cell death and apoptosis were measured to study the effects of nanoparticles in combination with both radiotherapy (RT) and photothermal therapy (PTT).

Cell transplantation is a potential therapeutic approach for repairing neuropathological and neurodegenerative disorders of central nervous system by replacing the degenerated cells with new ones. Among a variety of stem cell candidates to provide these new cells, olfactory ectomesenchymal stem cells (OE-MSCs) have attracted a great attention due to their neural crest origin, easy harvest, high proliferation, and autologous transplantation. Since there is no report on differentiation potential of these cells into motor neuron-like cells, we evaluated this potential using Real-time PCR, flowcytometry and immunocytochemistry after the treatment with differentiation cocktail containing retinoic acid and Sonic Hedgehog.

In this study, we explained in detail a targeted nano-photo-thermal therapy (NPTT) method to induce selective apoptosis in cancer cells. Folate-conjugated gold nanoparticles (F-AuNPs) were synthesized by tailoring the surface of AuNPs with folic acid to enhance the specificity of NPTT. KB cancer cells, as a folate receptor over-expressing cell line, and L929 normal cells with low level of folate receptors were incubated with the synthesized F-AuNPs and then irradiated with various laser intensities and exposure durations.
