Abstract

Vitamin K2 (Menaquinone-4), a derivative of vitamin K in the body is synthesized by intestinal bacteria. This vitamin is present at a higher concentration in the brain more than the other tissues. There is a potential ability for conversion of vitamin K derivatives to the type of K2 in the body. Vitamin K2 in turn is the main form of the vitamin K in the nervous system. These all together are indicating the importance of the functions of this vitamin in the central nervous system. Some of them are including its importance in the process of myelin synthesis and development of the nervous system. Vitamin K2 is known as one of the factors involved in the inflammatory processes. Actually vitamin K2 is associated with inflammation, pain, Alzheimer's, osteoporosis and some types of cancers. Regard to the probable role of vitamin K2 in the treatment of many human diseases that today have fallen within the biggest human concerns (such as cancer and neurodegenerative diseases), vitamin K2 is hoped to be considered in new research as an effective strategy for prevent or treatment of such diseases with minimum possible side effects.

Abstract

Introduction: Acute alcohol consumption leads to induction of lipid peroxidation in renal tissues, but its chronic consumption has moderate effects on biochemical and histological characteristics of this organ. Antioxidants have protective effects against ethanol-induced oxidative stress and tissue injury. The aim of this study was to assess antioxidant activity of Glycyrrhiza glabra leaf and stem extracts and the protective effect of its leaf extract on ethanol-induced nephrotoxicity.
 
Materials & methods: Total phenol and flavonoid contents of leaf and stem extracts of G. glabra were measured by Folin Ciocalteu and AlCl3 assays, respectively. Antioxidant activity of both extracts was assessed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging. In addition, protective effect of the leaf extract was assessed using biochemical and histological analyses of renal tissues of male Wistar rats, which were divided into four groups including group 1 or control (received 1 ml distilled water daily), group 2 or ethanol group (received 1 ml of 50% ethanol daily), group 3 or ethanol + leaf extract group (received 1 ml of 50% ethanol + 500 mg/kg leaf extract daily), and group 4 (received 500 mg/kg of leaf extract daily). All treatments are performed through intragastric administration. Biochemical and histological analyses were used for the evaluation of nephrotoxicity. For histological study, the samples were stained with Hematoxylin-Eosin and examined by light microscopy. Finally, all the data were analyzed by SPSS (Ver. 20) and grouped by Duncan's Multiple Range Test at P <0.05 level.
 
Findings: There was no significant difference between total phenol contents of the stem and leaf extracts. However, the stem extract showed a higher total flavonoid content than the leaf extract. Also, both the extracts showed higher antioxidant activities (86-93%) than that of ascorbic acid (71%). Results from biochemical analysis indicated a significant increase in superoxide dismutase (SOD) activity and H2O2 content in the renal tissues of ethanol-treated rats in comparison with other groups; however, there were no significant changes in total protein and malondialdehyde (MDA) contents. Results from histological examination showed that alcohol consumption intensity injured kidney tissues, which was effectively moderated by the studied extract.
 
Discussion & Conclusions: Results from the present study showed that G. glabra extract has biological activity and can be used in future as a new natural antioxidant in food and drug industries.

Abstract

Introduction: Increasing levels of free radicals in the ova reduce the quality of their fertilization. Investigations have revealed the elevated production of tissue and serum-free radicals in women with polycystic ovary syndrome. Sirtuin-3 is located in mitochondria and plays an important role in the deactivation of free radicals. This study aimed to investigate the expression of the Sirtuin-3 gene in the ova of polycystic ovary syndrome affected mice.
Material & Methods: Polycystic ovary syndrome was induced by the injection of estradiol valerate (40 mg/kg) in six NMRI mice (age: six weeks old; weight: 25±5); moreover, six mice were selected as a control group. Following the induction, the structure of the ovaries was examined using the histotechnique, and the serum levels of sex hormones were determined using ELISA. The ova were collected from the ovaries, and their RNA was extracted by a special kit and converted to cDNA. Real-Time PCR was performed to analyze the expression of Sirtuin-3, and the Gapdh gene was selected as an internal control.
(Ethic code: 97/6505)
Findings: In the mice with polycystic ovary syndrome, hydatid cysts were formed in the ovaries. Furthermore, serum FSH hormone levels decreased in the affected mice, while LH and testosterone levels elevated, compared to those in the control mice (P<0.001). The expression of Sirtuin-3 was reduced in the ova of mice with polycystic ovary syndrome, compared to that in healthy mice in the ratio of 0.18 (P<0.05).
Discussion & Conclusion: The result of the present study showed that the expression of the Sirtuin-3 gene was decreased in the ovum of mice with polycystic ovary syndrome. Moreover, the disrupted expression of the Sirtuin-3 in the ovum can be suggested as one of the causes of reduced quality of the ovum in patients with polycystic ovary syndrome.

Abstract

Introduction: The unique properties of silver nanoparticles (Ag-NPs) produced using plant extract make them attractive for use in medical and industrial applications. Bunium persicum from the Apiaceae family is native to Iran, Afghanistan, Pakistan, and some Central Asian countries, which is locally known as "Kermanin Black Cumin" in Iran. In this study, Ag-NPs were synthesized using methanol extract of B. persicum as the regenerating and stabilizing agent for the first time and were followed by the characterization and evaluation of its biological potency.
Material & Methods: Synthesis of Ag-NPs was conducted using the B. persicum extract. Ultraviolet-visible (UV-VIS) spectroscopy was used to detect the presence of nanoparticles. Scanning Electron Microscope (SEM) was also employed to visualize the surface morphology, shape, and size distribution of nanoparticles. Fourier Transform Infrared Spectroscopy (FTIR) is very sensitive to the chemical surface of nanoparticles and was utilized to identify functional groups in the nanoparticles. Cytotoxicity against cancer cell lines and antileishmanial activities were investigated using MTT assay, and the well diffusion method was used to detect the antibacterial property of the synthesized nanoparticles.
Findings: UV-VIS spectrum exhibits an absorption band at around 400-450 nm suggesting the formation of biological Ag-NPs. The size and morphological properties of nanoparticles were assessed by SEM which showed that particles have spherical shapes with a diameter of about 20-70 nm. Ag-NPs showed cytotoxicity against human glioblastoma cancer cell line A-172 (IC50:7.2 µg/ml) and breast cancer cell line MCF-7 (IC50:7.6 µg/ml) after 48 h treatment. Ag-NPs presented antimicrobial activity against Gram-positive and Gram-negative bacteria. The present study confirmed good antileishmanial activity against the promastigote and amastigote stages of Leishmania major. The IC50 values of Ag-NPs and Glucantime® were 73.89 and 16.17μg/mL for promastigote, as well as 171.02 and 398.21 μg/mL for amastigotes assays, respectively.
Discussion & Conclusion: The extract of B. persicum has the ability to reduce Ag+ ions to Ag nanoparticles. Moreover, the fabricated Ag-NPs have good cytotoxicity, antibacterial, and antileishmanial activities.

The cytotoxicity of the Titanium Dioxide nanoparticles was evaluated by the MTT assay, and relative gene expression was studied by Real Time PCR method.
Findings: The results showed that the synthesized Titanium Dioxide nanoparticles were spherical with a size range of 59 to 82 nm. The particles had a considerable anti-proliferative effect on liver cancer cells line with IC50 of 80 µg/mL. The treatment of the cancer cell line with TiO2@Gln-TSC NPs significantly increased the expression of the CASP3, BAX, and BCL2 by 2.8, 2.7, and 1.3 folds, respectively, which indicated the activation of apoptotic pathways in the treated cells.
Discussion & Conclusion: The results showed that the TiO2@Gln-TSC NPs could inhibit the proliferation of liver cancer cells line and by triggering the apoptosis pathway.

Abstract

Introduction: Assisted reproductive techniques and Preimplantation Genetic Test (PGT) are performed to detect aneuploidy to achieve a euploid baby's birth in infertile or low-fertility couples. miRNAs are single-stranded, non-coding RNA molecules and essential regulators of gene expression in various biological and physiological processes. The present study aimed to investigate some miRNAs damaged in the culture media of human embryos (as diagnostic biomarkers) and their relationship with the degree of aneuploidy of the embryo and assisted reproductive methods.
Material & Methods: The PGT cycles derived sperm intracytoplasmic injection (April 2021 to June 2021) were evaluated using fluorescence in situ hybridization (FISH). Following that, the culture medium of three euploids and three aneuploid embryos with an X sex chromosome (Turner) was collected and the expression of has-miR-199a-5p, has-miR-199b-3p has-miR-379-5p, has-miR-483-5p, has-miR-99a-5p, and has-miR-432-5p were investigated using quantitative reverse transcription polymerase chain reaction (RT-qPCR).
Findings: In the culture medium of euploid embryos, a significant increase was observed in the expression of three miRNAs, including hsa-miR-379-5p, hsa-miR-199a-5p, hsa-miR-199b-3p. Moreover, a decrease was detected in the expression of three miRNAs, including hsa-miR-432-5p, hsa -miR-483-5p, and hsa-miR-99a-5p, with a significant difference (P<0.0001). The expression of these miRNAs in the culture medium of Turner embryos with the model was the opposite.
Discussion & Conclusion: In examining the expression level of miRNAs investigated in this project, the increase in the expression of three miRNAs and the decrease in the expression of three other miRNAs in euploid embryos demonstrated the opposite expression pattern of the same miRNAs in Turner embryos. These results can be considered promising for using non-invasive methods instead of fetal biopsy in the diagnostic studies of the number of sex chromosomes.
