Evaluation of Endoplasmic Reticulum Stress in an Experimental Intestinal Ischemia-Reperfusion Model in Rats: The Role of Ozone Therapy and Trimetazidine. Biomolecules 2024; 14:1051. [PMID: 39334818 PMCID: PMC11430474 DOI: 10.3390/biom14091051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Revised: 08/15/2024] [Accepted: 08/16/2024] [Indexed: 09/30/2024] Open
Abstract
AIM The objective of the study was to assess the impact of ozone (O3) and trimetazidine on the intestines following ischemia-reperfusion (I/R) injury through the investigation of endoplasmic reticulum stress. METHODS Forty Sprague Dawley rats were separated into five groups. The groups were named as follows: control, O3, I/R, I/R + trimetazidine (TMZ), and I/R + O3. The control group had laparotomy and exploration of the superior mesenteric artery (SMA) only. Furthermore, alongside laparotomy and SMA exploration, an intraperitoneal (i.p.) administration of a 0.7 mg/kg ozone-oxygen (O3-O2) combination was given to the O3 group. In the experimental groups, the SMA was blocked with the silk suture ligation technique for a duration of 1 h and then restored to normal blood flow for another hour. In the I/R + O3 group, ozone was delivered i.p. at a dosage of 0.7 mg/kg, 30 min after ischemia. In the I/R + TMZ group, a dose of 20 mg/kg/day of trimetazidine was administered orally via gavage for a duration of 7 days, beginning 1 week prior to the induction of ischemia. Intestinal tissues were taken to assess indicators of intestinal mucosal injury and oxidative stress. RESULTS The level of the lipid peroxidation marker malondialdehyde (MDA) was significantly reduced in the experimental groups as compared to the I/R group (p < 0.05). The experimental groups had considerably greater levels of glutathione (GSH), which reflects antioxidant capacity, compared to the I/R group (p < 0.05). Nevertheless, the concentration of GSH was observed to be increased in the I/R + O3 group in comparison to the I/R + TMZ group (p < 0.05). The histopathological damage score showed a substantial decrease in the experimental groups as compared to the I/R group (p < 0.05). The I/R + O3 group had the lowest injury score. The experimental groups exhibited significantly reduced positivity of the endoplasmic reticulum (ER) stress markers C/EBP homologous protein (CHOP) and glucose-regulated protein (GRP)-78 compared to the I/R group (p < 0.05). CONCLUSIONS The findings provide evidence for the potential advantages of utilizing ozone therapy in the treatment of intestinal ischemia-reperfusion injury. Additionally, they propose that ozone should be assessed in more extensive clinical trials in the future as a therapeutic agent that can disrupt endoplasmic reticulum stress.

Abstract
PURPOSE OF REVIEW There are significant differences in the transmission rate and mortality rate of COVID-19 under environmental conditions such as seasons and climates. However, the impact of environmental factors on the role of the COVID-19 pandemic and the transmission mechanism of the SARS-CoV-2 is unclear. Therefore, a comprehensive understanding of the impact of environmental factors on COVID-19 can provide innovative insights for global epidemic prevention and control policies and COVID-19 related research. This review summarizes the evidence of the impact of different natural and social environmental factors on the transmission of COVID-19 through a comprehensive analysis of epidemiology and mechanism research. This will provide innovative inspiration for global epidemic prevention and control policies and provide reference for similar infectious diseases that may emerge in the future. RECENT FINDINGS Evidence reveals mechanisms by which natural environmental factors influence the transmission of COVID-19, including (i) virus survival and transport, (ii) immune system damage, (iii) inflammation, oxidative stress, and cell death, and (iiii) increasing risk of complications. All of these measures appear to be effective in controlling the spread or mortality of COVID-19: (1) reducing air pollution levels, (2) rational use of ozone disinfection and medical ozone therapy, (3) rational exposure to sunlight, (4) scientific ventilation and maintenance of indoor temperature and humidity, (5) control of population density, and (6) control of population movement. Our review indicates that with the continuous mutation of SARS-CoV-2, high temperature, high humidity, low air pollution levels, and low population density more likely to slow down the spread of the virus.

Abstract
OBJECTIVES We examine how well ozone/oxygen gas therapy treats chronic hepatitis C patients with varying degrees of liver fibrosis. Also to study the effect of giving multiple anti-oxidants with the ozone/oxygen gas mixture, to see if this addition would have any additive or synergistic effect. METHODS Two hundred and twenty three patients with chronic hepatitis C. Liver biopsies were carried out at after 12 weeks of administering an ozone/oxygen gas mixture. RESULTS The mean stage of fibrosis decreased from 1.98 to 1.41 and the mean grade of inflammation decreased from 10.08 to 7.94, both with a p value less than 0.001. After 12 weeks of treatment, mean PCR values increased. No single significant complication was recorded in a total of >9,000 settings of ozone therapy. CONCLUSIONS Ozone oxygen gas mixture is safe and effective in treatment of hepatic fibrosis due to chronic viral hepatitis C.

Abstract
Cancer lactate metabolic reprogramming induces an elevated level of extracellular lactate and H+, leading to an acidic immunosuppressive tumor microenvironment (TEM). High lactic acid level may affect the metabolic programs of various cells that comprise an antitumor immune response, therefore, restricting immune-mediated tumor destruction, and leading to therapeutic resistance and unsatisfactory prognosis. Here, we report a metal-phenolic coordination-based nanocomplex loaded with a natural polyphenol galloflavin, which inhibits the function of lactate dehydrogenase, reducing the production of lactic acid, and alleviating the acidic immunosuppressive TME. Besides, the co-entrapped natural polyphenol carnosic acid and the synthetic PEG-Ce6 polyphenol derivative (serving as a photosensitizer) could induce immunogenic cancer cell death upon laser irradiation, which further activates immune system and promotes immune cell recruitment and infiltration in tumor tissues. We demonstrated that this nanocomplex-based combinational therapy could reshape the TME and elicit immune responses in a murine breast cancer model, which provides a promising strategy to enhance the therapeutic efficiency of drug-resistant breast cancer.

Abstract
The ex vivo treatment of a limited volume of blood with gaseous oxygen-ozone (O2-O3) mixtures and its rapid reinfusion into the patient is a widespread medical procedure. O3 instantly reacts with the blood's antioxidant systems, disappearing before reinfusion, although the molecules formed act as messengers in the organism, inducing multiple antioxidant and anti-inflammatory responses. An appropriate dose of O3 is obviously essential to ensure both safety and therapeutic efficacy, and in recent years, the low-dose O3 concept has led to a significant reduction in the administered O3 concentrations. However, the molecular events triggered by such low concentrations in the blood still need to be fully elucidated. In this basic study, we analysed the molecular modifications induced ex vivo in sheep blood by 5 and 10 µg O3/mL O2 by means of a powerful metabolomics analysis in association with haemogas, light microscopy and bioanalytical assays. This combined approach revealed increased oxygenation and an increased antioxidant capacity in the O3-treated blood, which accorded with the literature. Moreover, original information was obtained on the impact of these low O3 concentrations on the metabolic pathways of amino acids, carbohydrates, lipids and nucleotides, with the modified metabolites being mostly involved in the preservation of the oxidant-antioxidant balance and in energy production.

Abstract
Background/Aim Epidural fibrosis is one of the problems that can be seen after spinal surgery. The aim of this study was to investigate the possible preventive role of medical ozone (O) treatment on epidural fibrosis. Materials and Methods Twenty-four Sprague Dawley rats were randomly split into four groups: control (C), O, laminectomy (L), and L+O groups. Animals in the C group were sacrificed at the beginning of the experiment. The L and L+O groups had L procedure, while O treatment was supplied for the O and O+L groups. After 42 days of follow-up, for histological evaluation and biochemical measurements, the ratio of epidural fibrosis and catalase (CAT) with malondialdehyde (MDA) levels in serum, respectively, were analyzed in terms of statistical differences. Results Histologically, a distinct difference was o bserved in the epidural space after O treatment. A significant difference in epidural fibrosis areas is found to be between the O, L, and O+L groups (P < 0,0001). There was no statistically significant difference between CAT and MDA levels that were obtained by spectrophotometric analysis. Conclusion Histological results suggest that medical O treatment after L can be used as an alternative method to prevent epidural fibrosis. Further studies with wide cohorts and interval measures are required to detail the effects of doses.
