According to related studies, their presence stands as the main reason of cancer associated fatalities. The fundamental feature of these cells is their ability to provide resistance towards conventional treatments or facilitate escaping routes, which include the overexpression of multifunctional ATP-binding cassette (ABC) efflux transporter gene family, metabolism reprogramming, and activation of survivance pathways . Conventional therapies are mainly capable of annihilating cancer cells, while lacking the ability to remove vital CSCs. The recurrence of tumors can be impeded through the targeting of CSCs by different therapies. Nanoparticles with unique properties have emerged as a promising approach for combating stem cancer cells. Therefore, the exertion of nanoparticles, especially metal nanoparticles ‐ based drug delivery systems in cancer imaging and remedial treatment, can surpass the obstacles of conventional treatments. Therefore, the possibility of achieving nonspecific toxicities through the administration of lower but more accurate targeted doses can be provided by the production of theranostic metal nanoparticles and the incorporation of payload drugs into metal nanoparticles carriers, which requires a particular focus on the significance of biomarker targeting for remedial purposes and the unique contrast‐enhancing features of theranostic metal nanoparticles for facilitating image‐guided delivery. Despite the benefits of using nanoparticles for treating cancer stem cells, yet it is necessary to surpass the numerous challenges and further conduct comprehensive researches.https://www.nanomedicine-rj.com/article_249479_1c95320768898368dc89422aded54740.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896420211101Effects of doping metal nanoparticles in hydroxyapatite in Improving the physical and chemical properties of dental implants32733624948010.22034/nmrj.2021.04.002ENFoadTosanStudent Research Committee, Semnan University of Medical Sciences, Semnan, Iran.NeginRahnamaSchool of Medicine, Semnan University of Medical Sciences, Semnan, Iran.DelaramSakhaeiSchool of Medicine, Sari branch, Islamic Azad University, Sari, Iran.Amir HosseinFathiAssistant professor, Dental Material Research Center and Department of Prosthodontics, School of Dentistry, Isfahan University of Medical Sciences, Isfahan, Iran.AmirYariDoctor of Dental Surgery, School of Dentistry/Dental Research Center, Tehran University of Medical Sciences, Tehran, Iran.Journal Article20211223There are strong proofs for the therapeutic benefits of dental implants utility in regards to the replacement of dental elements throughout the treatment of complete or partial edentulism. Many materials were used for the manufacturing of dental implants throughout the history of this field. Hydroxyapatite is one of the popular structures due to being highly biocompatible, however, its poor stability fences its application. Therefore, the approach of doping with other structures, such as metal nanoparticles, can be proposed to circumvent this obstacle. Various metal nanoparticles are exerted in the role of dopants, which include manganese, silver, magnesium ,cobalt, zinc, silicon, strontium, lithium,cerium, yttrium, neodymium, hafnium, erbium, and cadmium. According to available evidences, the doping of metal nanoparticles with hydroxyapatite can improve the obtained mechanical stability, biocompatibility, osteoinductivity, osteoinductivity, the integrity of bone tissues, antibacterial properties, and other features, which is effective in increasing their potential applications. Apart from the offered benefits, the process of doping metal nanoparticles in dental implants is still in its infancy and struggles with several challenges.https://www.nanomedicine-rj.com/article_249480_2987a476ca8a314f7c646fbdeb39c2fe.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896420211101Preparation and Characterization of PLGA Encapsulated Tamoxifen Citrate-Magnetite Nanoparticle Via Oil in Water Emulsion Evaporation Technique33734624948110.22034/nmrj.2021.04.003ENEmmellie LauraAlbertInstitute of Advanced Technology,

TAM is a good example of a drug that is difficult to dissolve. TAM is currently approved for the treatment of hormone-sensitive and early-stage breast cancer as an adjuvant endocrine therapy. The majority of the prescription medicine in today market is made up of poorly soluble, bioavailable, and quickly metabolized and eliminated drug which is a continuously challenges up to these days. Therefore, it is imperative to overcome this disadvantages by encapsulating TAM inside PLGA together with MNP for improved drug delivery. The MNP coated with oleic acid (OA) was synthesized using co-precipitation method and it is known as OAMNP. The fabricated nanohybrid is known as TAM-PLGA-OAMNP where the TAM was encapsulated together with OAMNP within PLGA. XRD results showed that OAMNP is Fe3O4. FTIR spectra revealed that the TAM was successfully encased into the PLGA structure. TAM-PLGA-OAMNP average size is about 131 ± 28 nm as shown in TEM results. The nanohybrid nanoparticles showed the absence of hysteresis loop indicative of superparamagnetic properties.https://www.nanomedicine-rj.com/article_249481_9bfbf0c924f8d8ecc31ef3cda2f26803.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896420211101Design and evaluation of sesamol loaded hyaluronic acid functionalized phospholipid nanovesicles: DPPH radical scavenging potential assay34735124948210.22034/nmrj.2021.04.004ENManish KumarGuptaSchool of Pharmaceutical Sciences, Jaipur National University, Jaipur, India- 3020170000-0001-5151-419XVipul ASansareSchool of Pharmaceutical Sciences, Jaipur National University, Jaipur, India- 3020170000-0002-1134-3549BirendraShrivastavaSchool of Pharmaceutical Sciences, Jaipur National University, Jagatpura, Jaipur,

Electrospray is a novel and interesting approach to prepare polymeric nanoparticles. In this study, effect of four independent parameters on size of nanoparticles, prepared via electrospray, was investigated using artificial neural networks (ANNs). The parameters included concentration of polymer, applied voltage, humidity and temperature, of which, the last two were investigated for the first time in this study.<br /><br />The developed ANNs model showed that there is a complex and non-linear relation between the four input parameters and the size of prepared nanoparticles. The model also showed that applied voltage and temperature had small and reverse effects on the size. However, the dominant factors determining the size of the nanoparticles were humidity and polymer concentration: an optimum value was required for obtaining the smallest size. The values above or lower the optimum value made the particle size of generated nanoparticles larger.https://www.nanomedicine-rj.com/article_249487_648ed2ca1f996e121a9d0dd82814fc9f.pdfTehran University of Medical SciencesNanomedicine Research Journal2476-34896420211101Fabrication and characterization of PLGA polymeric nanoparticles containing Berberine and its cytotoxicity on breast cancer cell (MCF-7)39640824948810.22034/nmrj.2021.04.009ENMohamadTaebpourDepatment of Medical Biotechnology, Faculty of Medicine, Shahid Sadoughi University of Medical sciences, Yazd, IranFatemehArastehMedical Nanotechnology & Tissue Engineering Research Center, Yazd Reproductive Sciences Institute, Shahid Sadoughi University of Medical Sciences, Yazd, IranMiladAkhlaghiDepartment of clinical biochemistry, Faculty of Medicine, Shahid Sadoughi University of Medical Sciences, Yazd, IranBibi FatemehHaghirosadatMedical Nanotechnology & Tissue Engineering Research Center, Yazd Reproductive Sciences Institute, Shahid Sadoughi University of Medical Sciences, Yazd, IranFatemehOroojalianDepartment of Advanced Sciences and Technologies in Medicine, School of Medicine, North Khorasan University of Medical Sciences, Bojnūrd, Iran0000-0002-6849-6853DavoodTofighiDepartment of Psychology, University of New Mexico, Albuquerque, New Mexico, USAJournal Article20211205Breast cancer is one of the most common types of cancer in the world which threatening the lives of millions of people every year.
