In this work, we experimentally studied the structure and magnetic properties of epitaxially grown ultrathin Pd/Co/Ta films. We have studied the effect of Ta on the structural and magnetic properties of Pd/Co epitaxial films. The deposition of a Ta layer on an epitaxial Co layer leads to a decrease in the saturation magnetization of the film due to strong magnetic disordering and the formation of a dead magnetic layer with a thickness of about 0.5 nm. Perpendicular magnetic anisotropy is observed for Co layer thicknesses less than 1.3 nm. The volume and surface components of magnetic anisotropy are determined. Additionally, the Dzyaloshinskii–Moriya interaction (DMI) is observed in epitaxial films with perpendicular magnetic anisotropy, with a DMI field value of about 30 mT.

Human health is affected by various factors such as air pollutants. Exposure to toxic air pollutants is impaired fertility in men and women. The purpose of this review study was investigation of the effect of toxic air pollutants on fertility and birth rate. Databases used to for searched were the PubMed, Web of Science, Springer and Science Direct (Scopus) and Google Scholar. Identify all relevant studies published 1999–2022. In this study, according to databases five hundred articles were retrieved. 33 studies were screened after review and 19 full-text articles entered into the analysis process. Finally, 11 articles were selected in this study. The literature signs a notable health effects from toxic air pollutants and increase risk of infertility in men and women and having a variety of reproductive system cancers such as prostate, bladder, ovary, kidney and uterus. According to the finding toxic air pollutants can increase the risk infertility in men and women, incidence of cancers of reproductive system and decrease the birth rate. Activities that play an important role in reducing the health effects of toxic air pollutants such as infertility in men and women and reducing the population rate of communities are improving the quality of fuel used in the home, car, industries, changing production processes in large industries, installing catalysts to reduce emissions in cars, use more public transportation, plant trees and increase green space per capita, increase public awareness about various effects of toxic air pollutants and protective measures.

Mesenchymal stem cells (MSCs) are one of the most prominent cells in the bone marrow. MSCs can affect acute lymphocytic leukemia (ALL) cells under hypoxic conditions. With this aim, we used MOLT‐4 cells as simulators of ALL cells cocultured with bone marrow mesenchymal stem cells (BMMSCs) under hypoxic conditions in vitro. Then, mRNA and protein expression of the MAT2A, PDK1, and HK2 genes were evaluated by real‐time PCR and Western blot which was also followed by apoptosis measurement by a flow‐cytometric method. Next, the methylation status of the target genes was investigated by MS‐qPCR. Additionally, candidate gene expressions were examined after treatment with rapamycin using 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT) assay. We found that the mRNA expression of the candidate genes was augmented under the hypoxic condition in which MAT2A was upregulated in cocultured cells compared to MOLT‐4, while HK2 and PDK1 were downregulated. Moreover, we found an association between gene expression and promoter methylation levels of target genes. Besides, expressions of the candidate genes were decreased, while their methylation levels were promoted following treatment with rapamycin. Our results suggest an important role for the BMMSC in regulating the methylation of genes involved in cell survival in hypoxia conditions; however, we found no evidence to prove the MSCs' effect on directing malignant lymphoblastic cells to apoptosis.
