Development of mobile application for cervical cancer screening in women: Protocol of a multi-phase study.

Background: Cervical cancer is one of the most common cancers in women. It is considered preventable due to the possibility of screening. The common barriers to cervical cancer screening include lack of knowledge, lack of time, and wrong beliefs.

Prediction of cervical cancer screening: application of the information-motivation-behavioral skills model.

Introduction: Screening is an effective method for preventing cervical cancer. The present study aimed to determine the predictability of cervical cancer screening using the information-motivation-behavioral skills (IMB) model, as this model can help understand the factors that influence health-related behaviors.

Method: The present cross-sectional study examined 310 women aged 20 to 60 in Isfahan, Iran, between 2020 and 2021.

Diabetic wound healing function of PCL/cellulose acetate nanofiber engineered with chitosan/cerium oxide nanoparticles.

The use of cerium oxide nanoparticles (CeONPs) in diabetic wound repair substances has shown promising results. Therefore, the study was conducted to introduce a novel nano-based wound dressing containing chitosan nanoparticles encapsulated with green synthesized cerium oxide nanoparticles using Thymus vulgaris extract (CeO-CSNPs). The physical properties and structure of the nanoparticles were analyzed using XRD, DLS, FESEM and FTIR techniques.

Analysis of the molecular alterations in cancer cells following nanotechnology-assisted targeted radiotherapy using Raman spectroscopy.

The study unveiled an innovative strategy for precise radiation targeting in cancer treatment, along with the monitoring of molecular changes induced by this therapeutic approach. In this research, we explored the impact of administering anti-HER2-AgNPs nanoconjugates either individually or in conjunction with gamma irradiation on the viability of SKBR3 breast cancer cells. The utilization of nanoconjugates resulted in an enhancement of cellular sensitivity toward radiation.

Polyethylenimine-based iron oxide nanoparticles enhance cisplatin toxicity in ovarian cancer cells in the presence of a static magnetic field.

Background: Drug resistance in cancer cells is a major concern in chemotherapy. Cisplatin (CIS) is one of the most effective chemotherapeutics for ovarian cancer. Here, we investigated an experimental approach to increase CIS cytotoxicity and overcome cell resistance using nanoparticle-based combination treatments.

Estimating the two graph dextran-stearic acid-spermine polymers based on iron oxide nanoparticles as carrier for gene delivery.

Non-viral gene carriers have shown noticeable potential in gene delivery because of limited side effects, biocompatibility, simplicity, and the ability to take advantage of electrostatic interactions. However, the low transfection rate of non-viral vectors under physiological conditions is controversial. This study aimed to decrease the transfection time using a static magnetic field.

New phosphoramides containing imidazolidine moiety as anticancer agents: An experimental and computational study.

In this study, two new phosphoramides containing imidazolidine; diphenyl (2-imidazolidinone-1-yl)phosphonate (DIOP) and diphenyl (2-Imidazolidinethione -1-yl)phosphonate (DITP) as cytotoxic agents, were synthesized and characterized by using IR, H NMR, C NMR, P NMR, Mass spectroscopy and elemental analysis. The target products were obtained in moderate to good yields (69-86%) by using the time (3 h) and solvent (MeCN). The crystal structure of DIOP was investigated using X-ray crystallography.

Influence of Static Magnetic Field on HeLa and Huo2 Cells in the Presence of Aloe vera Extract.

This research aimed to assess the impact of static magnetic field (SMF) on apoptosis rate and cell cycle progression in the presence of Aloe vera Crude Extract (ACE) in normal (Huo2) and cancer cells (HeLa). The specimens were split into one untreated group (control) and two experimental groups, including treatment with ACE (Alo) and compound treatment with SMF and ACE (Alo+SMF). MTT assay determined the IC50 value, and flow cytometry was employed to evaluate cell cycle distribution and apoptosis rates.

Improved features of a highly stable protease from Penaeus vannamei by immobilization on glutaraldehyde activated graphene oxide nanosheets.

In this study, we report the synthesis of graphene oxide nanosheets (GON) by a modified Hummers method. Then, a protease purified from the Penaeus vannamei shrimp was immobilized on the GON activated with glutaraldehyde. Several techniques such as SEM, DLS and FTIR were applied to characterize the different nano-structures at the different levels.

Stable morphological-physiological and neural protein expression changes in rat bone marrow mesenchymal stem cells treated with electromagnetic field and nitric oxide.

As an external physical factor, electromagnetic field (EMF) may influence cellular processes and nitric oxide (NO) by serving as a secondary messenger molecule in intracellular signaling cascades. Effects of these factors were evaluated simultaneously on viability, morphology, and variation of calcium ion content, and neural protein marker expression in rat bone marrow mesenchymal stem cells (BMSCs). The mesenchymal stem cells were isolated from rat bone marrow and cultured.

Effect of vermicompost on growth, yield and nutrition status of tomato (Lycopersicum esculentum).

An experiment was conducted to determine the effects of vermicompost on growth, yield and fruit quality of tomato (Lycopersicum esculentum var. Super Beta) in a field condition. The experiment was a randomized complete block design with four replications.
