    Abstract Objectives: Juvenile idiopathic arthritis (JIA) is a childhood autoimmune rheumatoid disease. Past studies have confirmed that JIA is a complex disease, which means that genes and environmental factors affect the aetiology of the disease. In this study, we analysed the expression of interleukin 32, forkhead box P3 (FOXP3), methyl-CpG binding domain protein 1 (MBD1), and methyl-CpG-binding protein 2 (MECP2) in peripheral blood mononuclear cells of children with JIA in comparison with the expression of those in healthy children. Interleukin 32 is an inflammatory factor, FOXP3 is a transcription factor, and MBD1 and MECP2 are binding proteins that bind to the methylated deoxyribonucleic acid (DNA).
    Material and methods: We collected blood from JIA patients who had been diagnosed and classified into clinical subtypes by a rheumatologist from the division of paediatric rheumatology. Healthy children, whose clinical and preclinical analysis confirmed they had no disease and just came to the hospital for a check-up or minor surgical procedures were considered as a control group. Age and gender were matched in patients and the control group. Total ribonucleic acid was extracted from blood, and cDNA was synthesized. Eventually, the transcript levels were analysed by quantitative polymerase chain reaction, and statistical analysis was carried out.
    Results: Statistical analysis of gene expressions in young females affected by JIA demonstrated that MECP2 and FOXP3 were increased significantly (
    Conclusions: Different expression levels of the mentioned genes between affected young females and males result from hormones in both gender and also methotrexate (MTX) drug. Also, the reason affected young females are more prone to JIA than males can be the lower level of FOXP3 expression in healthy females than healthy males.

    Abstract Circular RNAs (circRNAs) as a new class of non-coding RNAs (ncRNAs) play role in gene regulation in multicellular organisms via various interactions with nucleic acids, proteins and particularly microRNAs. They have been found to be involved in a number of biological functions particularly in regulation of cell cycle, and extracellular interactions. Thus, dysregulation of circRNAs is found to be associated with several human diseases and especially numerous types of cancers. ciRS-7 is an example of circRNAs which have been studied in a number of human diseases like neurological diseases, diabetes mellitus, and importantly different malignancies. It has been found to regulate cell proliferation and malignant features in cancer cells. CiRS-7 is upregulated in several cancers and its overexpression promoted malignant phenotype of cancer cells via enhancing cell proliferation, migration, and invasion in vitro and in vivo. As a competing endogenous RNA (ceRNA), ciRS-7 is found to sponge miR-7 as the most common miRNA target in interaction together. Functional analyses show role of ciRS-7 in downregulation of miR-7 and involvement of a series of signaling pathways in turn through them it is believed that ciRS-7 regulates malignant behaviors of cancer cells. Clinical studies demonstrate upregulation of ciRS-7 in cancer tissues compared to their non-cancerous adjacent tissues, correlation with worse clinicopathological features in cancerous patients and an independent prognostic factor. In this review, we have an overview to the role of ciRS-7 in development and progression of cancer and also assess its potentials as a diagnostic and prognostic biomarker in human cancers.

    Abstract Background: Obesity is regarded a global public health crisis. It has been implicated in a variety of health problems, but when it comes to male fertility, how and to what extent obesity affects it are poorly understood. Accordingly, semen samples from 32 individuals with obesity (body mass index (BMI) ≥ 30 kg/m
    Results: Based on our findings, there was a marked reduction in relative STL in individuals with obesity as compared to the normal-weight group. We also found a significant negative correlation between relative STL and age, BMI, DFI, percentage of sperm with immature chromatin, and intracellular ROS levels in patients with obesity. In the normal-weight group, relative STL was only negatively correlated with DFI and intracellular ROS levels. Regarding mRNA expression, there was considerable upregulation of Beclin1, ULK1, and BCL2 in the group with obesity compared to the normal-weight group. Obesity was also found to be associated with a considerable decline in semen volume, total sperm count, progressive motility, and viability in comparison to normal-weight individuals. Furthermore, obesity was associated with considerably higher percentages of DFI, sperm with immature chromatin, late-stage apoptosis, and elevated ROS levels.
    Conclusion: According to our findings, obesity is associated with sperm telomere shortening and aberrant autophagy-related mRNA expression. It should be emphasized that telomere shortening in sperm may be an indirect consequence of obesity due to the oxidative stress associated with the condition. Nevertheless, further investigation is required for a more comprehensive understanding.

    Abstract Background: Genome manipulation of Leishmania species and the creation of modified strains are widely employed strategies for various purposes, including gene function studies, the development of live attenuated vaccines, and the engineering of host cells for protein production.
    Objective: Despite the introduction of novel manipulation approaches like CRISPR/Cas9 technology with significant advancements in recent years, the development of a reliable protocol for efficiently and precisely altering the genes of Leishmania strains remains a challenging endeavor. Following the successful adaptation of the CRISPR/Cas9 system for higher eukaryotic cells, several research groups have endeavored to apply this system to manipulate the genome of Leishmania.
    Results: Despite the substantial differences between Leishmania and higher eukaryotes, the CRISPR/Cas9 system has been effectively tested and applied in Leishmania.  CONCLUSION: This comprehensive review summarizes all the CRISPR/Cas9 systems that have been employed in Leishmania, providing details on their methods and the expression systems for Cas9 and gRNA. The review also explores the various applications of the CRISPR system in Leishmania, including the deletion of multicopy gene families, the development of the Leishmania vaccine, complete gene deletions, investigations into chromosomal translocations, protein tagging, gene replacement, large-scale gene knockout, genome editing through cytosine base replacement, and its innovative use in the detection of Leishmania. In addition, the review offers an up-to-date overview of all double-strand break repair mechanisms in Leishmania.

    Abstract Breast cancer is the second cause of death in the world. Ionising radiation is a potent mutagen that can cause DNA damage, chromosomes breakage, and cell death. In the present study, radiotherapy and nanoparticle-antibodies (ABs) have been combined to enhance the efficacy of cancer cell treatment. Silver nanoparticles (SNP) were synthesised, coated with anti-HER2, and then characterised with different techniques such as X-ray diffraction, dynamic light scattering, transmission electron microscopy, Fourier transform infrared, and UV-Vis spectroscopy. SKBR3 cells were irradiated with cobalt-60 in the presence of nanoparticle-AB as the drug. Cell viability was measured using the diphenyltetrazolium bromide assay, and the cellular status was assessed by Raman spectroscopy. Irradiation considerably decreased cell viability proportionate to the dose increase and post-irradiation time. The surface-enhanced Raman spectroscopy increased the signal in the presence of SNP. Increasing the dose to 2 Gy increased the irradiation resistance, and higher dose increases (4 and 6 Gy) enhanced the irradiation sensitivity. Moreover, the cellular changes induced by irradiation in the presence of the drug were stable after 48 h. The authors results introduced the combination of the drug with radiation as an effective treatment for cancer and Raman spectroscopy as a suitable tool to diagnose effective irradiation doses.

    Abstract Small double-strand RNA (dsRNA) molecules can activate endogenous genes via an RNA-based promoter targeting mechanism. RNA activation (RNAa) is an evolutionarily conserved mechanism present in diverse eukaryotic organisms ranging from nematodes to humans. Small activating RNAs (saRNAs) involved in RNAa have been successfully used to activate gene expression in cultured cells, and thereby this emergent technique might allow us to develop various biotechnological applications, without the need to synthesize hazardous construct systems harboring exogenous DNA sequences. Accordingly, this thematic issue aims to provide insights into how RNAa cellular machinery can be harnessed to activate gene expression leading to a more effective clinical treatment of various diseases.

    Abstract Weakened wound healing is a popular, severe complication of patients with diabetes which poses a risk for foot infection and amputation. Researchers have searched for new treatments for treating diabetic foot ulcers (DFUs) in recent years. In this case report, for the first time, we applied photobiomodulation therapy (PBMT) and Altrazeal powder together to treat a severe case of DFU in a 47-year-old woman who was suffering from type 1 diabetes. Along with the progress of combination therapy, we observed that the ulcer area was significantly reduced, and the wound healed within 16 weeks. Furthermore, dermatitis and purulent secretion were treated, and the pain was reduced. This reported case study indicated the beneficial effect of the combination of PBMT and Altrazeal powder for the healing of a severe DFU in a patient with type one diabetes. The combined application of PBMT plus Altrazeal powder demonstrated an additive effect. Further clinical trials in the clinical setting are suggested to validate the results further. Besides, more studies in preclinical models are suggested to find the mechanism of the action of combination therapy.
