Rheumatoid arthritis (RA) is a chronic inflammatory joint disorder that causes systemic inflammat... more Rheumatoid arthritis (RA) is a chronic inflammatory joint disorder that causes systemic inflammation, autoimmunity, and joint abnormalities that result in permanent disability. Exosomes are nanosized extracellular particles found in mammals (40–100 nm). They are a transporter of lipids, proteins, and genetic material involved in mammalian cell–cell signaling, biological processes, and cell signaling. Exosomes have been identified as playing a role in rheumatoid arthritis-related joint inflammation (RA). Uniquely functioning extracellular vesicles (EVs) are responsible for the transport of autoantigens and mediators between distant cells. In addition, paracrine factors, such as exosomes, modulate the immunomodulatory function of mesenchymal stem cells (MSCs). In addition to transporting genetic information, exosomes convey miRNAs between cells and have been studied as drug delivery vehicles. In animal models, it has been observed that MSCs secrete EVs with immunomodulatory properties...

GCs, also known as nurse cells, are an important protective element for the growth and survival of oocytes. Oocytes, which lack some of the metabolic processes, require granulosa cells for their development. Objectives: This manuscript was provided to explain the protocol of GCs primary culture extracted from NMRI mice ovaries. Methods: For choosing the optimum protocol, we used two methods with different culture mediums to obtain more GCs and expedite the process. Hematoxylin and Eosin (H&E) staining and flow cytometry were used to analyze the type of extracted cells from ovaries. Besides, we evaluated the effect of crocin and DPP as two common natural products in Iran on the proliferation of these cells via MTT assay. Results: Second protocol method and alpha-MEM culture medium were chosen based on the results. Our findings from HE staining and flow cytometry pro...

Common modalities do not offer lasting saffron preservation and it is urgent to develop novel packaging approaches from renewable resources and prevent packaging waste. Here, simultaneous decontamination and quality maintenance of saffron is demonstrated, for the first time, through the synergistic application of nano-clay-loaded carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) nanocomposites (CNCs) and cold plasmas (CP). Compared to the separate uses of CP and CMC/PVA/nano clay, our results confirm the synergies between CP and CMC/PVA/nano clay cause complete inactivation of Escherichia coli bacteria, while not significantly affecting the concentrations of the essential saffron components (safranal, crocin, and picrocrocin). Overall, the CP-treated CMC/PVA/nano clay fosters saffron preservation, through contamination removal and quality maintenance...

X-ray diffraction patterns confirmed the formation of the PbS cubic phase in all of the nanocomposites. FE-SEM images showed that PbS NPs are cubic in shape and the doping can alter the shape of grains. DLS analysis applied for solution NPs exhibited a 175 nm size distribution for PbS NPs and decreased by doping Ag and Sn to almost 100 nm and 110 nm, respectively. Optical absorption spectra showed the blue phenomena and the band gaps of Sn: PbS/PVA and Ag: PbS/PVA nanocomposites increased with adding Sn and Ag from 3.08 eV for pure PVA/PbS to 3.33 eV for Sn doped and 3.43 eV for Ag-doped samples. The nonlinear refractive index is decreased from 0.55 m2 W−1 for pure PVA/PbS to 0.11 m2 W−1 and 0.13 m2 W−1 for Sn and Ag-doped samples, respectively. Hence, doping Ag and Sn enhanced the optical sensitivi...

Herein, we propose a green, low-cost, and environmentally friendly synthesis method for titanium dioxide nanotubes using the anodizing process. The anodizing process was carried out in a chemical cell, and the effect of voltage and anodizing time on the creation of pure titanium dioxide nanotubes was investigated. A grade 4 titanium sheet with a thickness of 1 mm was utilized to make titanium oxide nanotubes. First, the titanium sheet was sliced into 1.5 × 1.5 cm squares, and the samples were sanded and polished with SiC sanding sheets ranging in grade from 180 to 3000. After that, the samples were immersed in an ultrasonic bath for 15 minutes to degrease and remove surface impurities in an equal amount of acetone-ethanol solution. A two-electrode cell was utilized for anodizing, with a graphite electrode as the cathode, a titanium sample as the anode, and an electrolyte solution containin...

Different electrolyte solution concentrations and anodization voltages altered wall thicknesses and tube diameters, according to our observations from the XRD pattern, TEM pictures, and optical examinations. While the band gap and band edge values of TiO2 nanotubes altered with different anodization voltages, the band gap, and band edge values remained constant. Furthermore, we discovered that at various electrolyte solution concentrations, the optimum solution concentration for growing compact TiO2 nanotubes is 70 percent porosity. Various morphologies of TiO2 nanostructures, such as sheet, rod, and tube, were obtained in the next section of the study by modifying the experimental settings (e.g., growth methods, differently used gases, and process temperatures).

We cultured GCS cells and the carboplatin-resistant SKOV-3 cells in vitro until the exponential growth phase and then treated with the different exposure time of CAP and PAM. We performed MTT assay to determine the proliferation of ovarian cells. Besides, morphological change and apoptosis and necrosis of cells were evaluated. Our results revealed that CAP and PAM with inducing selective effect, overcome the carboplatin resistance in human ovarian cancer. we found that there was a significant difference in the response of normal and cancer cells to CAP and PAM treatments. Our results showed that normal cells are more sensitive to CAP treatment. Thus, under CAP treatment, we found a further decrease in normal cell survival respect to PAM treatment. Given that the main difference between CAP and PAM methods is in the physical factors used in CAP treatment, it is expected that normal cells have been more sensitized than cancer cells to physical factors, such as the electric field and UV radiation. It is a promising finding because PAM can cover essential drawbacks of CAP treatment. Taken together, our data suggest that physical factors along with chemical factors have important role roles in the selective induction of CAP on ovarian cells.

The role of steroid hormones from fetal life to adulthood regulate by a wide variety of developmental and physiological processes. Qualitative regulation determining the type of steroid to be produced is mediated by many enzymes and cofactors. Steroidogenic enzymes fall into two groups: cytochrome P45 (CYP) or HSD enzymes and hydroxysteroid dehydrogenases. Granulosa cells are responsible for estrogens synthesis and essential for the development and survival of oocyte. Non-thermal plasma is a cocktail of chemical and physical factors such as short-lived reactive species, long-lived reactive species, electromagnetic field, and ultraviolet radiation. Recently, plasma has attracted attention in various fields of medicine. Here, we examine for the first time the efficiency of plasma, Crocus sativus L., and Date palm pollen (DPP) on Granulosa cells which are important and necessary for ovarian steroidogenesis. Based on our observation, we expect plasma acts ac a steroidogenesis inducer agent.
