During CO poisoning, the body increases anti-inflammatory proteins, including heme oxygenase-1 (HO-1), in response to oxidative stress. Considering the myocardial injury resulting from CO poisoning and the lack of sufficient information about the effect of HBOT on HO-1, the present study evaluated the effect of hyperbaric oxygen therapy on heme oxygenase-1 (HO-1) in patients with acute carbon monoxide poisoning and myocardial injury. In this regard, in a before-after Quasi-Experimental study, 20 patients with carbon monoxide poisoning and myocardial injury were studied. All patients underwent 40 daily hyperbaric oxygen therapy sessions for 90 minutes at a pressure of 2.4 ATA. Also, 20 healthy individuals, as a control group, were participated. To evaluate and compare the mRNA level of the HO-1 gene, the Real-time PCR technique was used. Paired t-test was used to compare the two indices of 6min walking distance and pulmonary arterial pressure (PAP) before and after the intervention. The results showed that the difference during 12 weeks was 8.65 ± 4.91 for PAP, and this reduction in pressure was statistically significant (P = 0.0092). The distance traveled increased by 28 ± 10.88 m in 6 minutes at the end of the study (P = 0.0084). Regarding the expression level of HO-1, the results showed that the expression level in the intervention group before the test had a significant increase compared to the control group (p = 0.0004). However, after hyperbaric oxygen therapy, the expression of this gene decreased significantly, and there was no statistically significant difference with the control group (p = 0.062). Overall, the results showed that HBOT significantly decreased HO-1 gene expression in CO poisoning and myocardial injury patients. It indicates the importance of HBOT in the treatment and compensation of cardiac tissue damage caused by CO poisoning.</p>","PeriodicalId":520584,"journal":{"name":"Cellular and molecular biology (Noisy-le-Grand, France)","volume":" ","pages":"36-39"},"PeriodicalIF":1.6,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33504970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to compare intravenous anesthesia with and without thoracic epidural block (dezocine and ropivacaine) on oxygen saturation during lung ventilation in patients undergoing lung resection surgery. For this purpose, this study was performed as a double-blind, randomized clinical trial. Sixty patients who were candidates for lung resection were divided into two intervention groups (thoracic epidural block with dezocine and ropivacaine and intravenous anesthesia) and a control group (placebo thoracic epidural block and intravenous anesthesia). Hemodynamic variables, Aldert score, and possible complications were compared between the two groups before surgery and after recovery. Also, the expression level of the IDO gene was evaluated using the real-time PCR technique. SPSS, t-test, Mann-Whitney U, Chi-square, and Fisher performed data analysis and comparison.  The results showed that the changes in hemodynamic variables and PaO2, SaO2, and ETCO2 were not statistically significant between the two groups. Aldrete's score at entry and exit of recovery was similar between the two groups. During the recovery period, the percentage of pain or chills in the group under complete intravenous anesthesia was significantly higher. There was no significant difference between the two groups regarding the frequency of nausea and hypotension. Also, the results of IDO gene expression showed that general anesthesia with the thoracic epidural block (dezocine and ropivacaine), which is involved in inducing immunological tolerance and suppressing immune responses, has no significant effect. The stress of performing surgery before surgery can play a role in suppressing the patient's immunity, and anesthesia of the thoracic epidural block (dezocine and ropivacaine) has no significant effect on IDO expression.

In addition, immunoprecipitation study showed that HuR directly interacted with Snail, a repressor of E-cadherin, and upregulated the expression of Snail in A549 cells. These combined results suggested that the effect of HuR on A549 migration and invasion was realized by stabilizing and increasing the expression of Snail, which in-turn interfered with the expression of E-cadherin.

In this study, the virtual screening was performed among 200 compounds retrieved from several resources for the searching of potent lead against Caspase 8 (Casp8). Cryptophycin 52 was found to have a strong inhibiting efficacy based on the free energy of binding with the active site of Casp8. The lowest binding energy was found to be -8.05 kcal/mole and was further analyzed for molecular dynamic simulation. Casp8 enzyme was determined to interact with cryptophycin 52 through twelve amino acid residues, specifically ARG260, SER316, GLY318, ASP319, THR337, VAL354, PHE355, PHE356, ILE357, GLN358, ALA359 and CYS360 along with six hydrogen bond particular, ILE357:N-UNK1: O7, UNK1: O14-PHE355:O, UNK1: C25-PHE355:O, UNK1: C35-THR337:O, UNK1: H65-HE355:O and UNK1: C25-PHE356.
