In this investigation coconut oil was subjected to 0 to 5 L/min of ozone for 3 h and the chemical composition of both crude and ozonized oil was valued via Gas Chromatography-Mass Spectrometry (GC-MS). Some biological tests were done including antibacterial action versus Helicobacter pylori, anti-biofilm activity versus H. pylori, anti-hemolytic activity in the existence of H. pylori, anti-Alzheimer action, and cytotoxic effect towards A-413 cancer cell line to determine the activity of coconut oil and upon exposure to ozone. Fifteen compounds were detected in the coconut oil crude and ozonized oils where the fatty acid esters were the most common molecules in crude coconut oil, whereas alkenes were the most predominant compounds in ozonized coconut oil. A slight elevation of antibacterial action towards H. pylori from 23.0 ± 0.1 to 28.2 ± 0.5 mm was displayed upon exposure of the coconut oil to ozone. Both crude and ozonized coconut oil showed a bactericidal effect with MICs = 62.5 ± 0.1, 125.0 ± 0.2 µg/mL and MBCs = 15.62 ± 0.2, 31.25 0.2 µg/mL for crude and ozonized oil, respectively. A significant elevation in anti-biofilm activity was found upon using 25% of MBCs of ozonized oil relative to crude oil. A dramatic rise was observed in anti-hemolytic activity upon using 25 and 75% of MICs of ozonized oil relative to crude one. A notable elevation of anti-Alzheimer impact was evident upon exposing coconut oil to ozone. Besides, the cytotoxic impact towards A-431 cells was slightly increased after exposing the oil to ozone.

The addition of these supplements increased asymptotic gas production across all forages while simultaneously reducing CH<sub>4</sub>, CO, and H<sub>2</sub>S emissions, though the extent of reduction varied depending on forage type. Moreover, the treatments improved fermentation profiles, including pH and dry matter digestibility, and significantly influenced CH<sub>4</sub> conversion efficiency (CH<sub>4</sub>:ME, CH<sub>4</sub>:OM, and CH<sub>4</sub>:SCFA; P < 0.05).

The results of recent researches consider the relationship between microbiota and the immune system as a double-edged sword. Considering that the relationship between the composition of intestinal microbiota and the immunological and clinical status of the body has been confirmed, it is very important to investigate the effect of each genus and species of bacteria on the state of the immune system. The current study was determined using 16S rRNA gene sequencing to explore the 4 selected gut microbiota from 25 people suffering from rheumatism (RA group) with a time interval of at least 3 years from the onset of the disease and 25 Healthy people by real time PCR. Gut dysbiosis in patients with rheumatoid arthritis (RA) is identified alongside key serological and clinical markers such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), immunofluorescence (IF), anti-cyclic citrullinated peptide (Anti-CCP), white blood cell count (WBC), mean corpuscular volume (MCV), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), Platelet count (PLT), thyroid-stimulating hormone (TSH), creatinine (Cr), and hemoglobin (Hb). Additionally, data from individuals with incomplete or unverified records were excluded from the study to ensure accuracy and reliability. Bacteroides fragilis, Roseburia faecis and Fusobacterium nucleatum genera showed a much lower median in Rheumatoid arthritis patients in comparison with healthy people (P > 0.001, p = 0.002, P < 0.001 respectively). While the difference in the median of E. coli genera was not significant in the two studied groups (p = 0.31). In such a way that the change in the Gut normal flora homeostasis and the reduction of beneficial bacteria such as Bacteroides fragilis, Roseburia faecis, Fusobacterium nucleatum genera, may stimulate the immune system to initiate autoimmunity.</p>","PeriodicalId":7537,"journal":{"name":"AMB Express","volume":"14 1","pages":"138"},"PeriodicalIF":3.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11655736/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142852048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
