“…Free radical generation is normally regulated by antioxidants. Antioxidants have the ability to stabilize or inactivate free radicals before they cause harm to the various cell components [38]. The findings in Table 1 above were in line with other studies, including those by Gökdemir et al who examined TAS in MI patients and found a significant decrease in the patient group compared to that of healthy participants [39] and Shahzad et al who also found a decrease in TAS in MI patients [40].…”

One of the most prevalent illnesses in developing countries is myocardial infarction (MI), which develops when the heart's blood supply is suddenly interrupted and causes tissue damage. It is connected to several metabolic risk factors, including diabetes, hypertension, and obesity. The objective of this study was to assess how oxidative stress (OS) contributed to the pathophysiology of MI and T2DM. The current study examined 152 male samples, including 52 MI patients without T2DM (G1), 50 MI patients with T2DM (G2), and 50 seemingly healthy men as controls (C). The levels of fasting blood sugar (FBS), C-reactive protein (CRP), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), malondialdehyde (MDA), and total peroxidase activity were assessed. Based on the results, CRP levels increased significantly in both the G1 and G2 groups compared to the C group, with G2 reporting greater significant increases than G1. Both the G1 and G2 groups considerably exceeded the C group in terms of TOS, OSI, MDA, and total peroxidase activity. In contrast to the C group, the TAS was found to be much lower in the G1 and G2 groups. Additionally, there were no noticeable variations in the TOS, TAS, OSI, MDA, or total peroxidase activity between the G1 and G2 groups. According to our findings, individuals with MI and T2DM had an increased OS and a diminished antioxidant system. Consequently, OS may be crucial to the pathophysiology and prognosis of MI and T2DM.

“…While the decrease in TAC was more obvious in the smoker workers than in the nonsmoker workers. The results about the effect of smoking on TOS level and on OSI is in line with the result of Ozbay and Dulgers results that pointed to the presence of a significant increase in lipid peroxidation [25] and with Morrow et al Ref [26]as well as with Shermatov et. al., [27], who reported that the determined (TOS) level was significantly higher in children exposed to secondhand cigarette smoke than that of the group who not exposed to cigarette smoke [28].…”

The goal of this study was to investigate the effect of the pollutants emitted from the combustion of heavy fuel oil (HFO) on the workers’ health who are working at this unit. This was done by checking the changes in serum and saliva total oxidant status ( TOS), total antioxidant capacity (TAC) and the oxidative stress index (OSI).The participants of the study were male workers (N= 83) who are working at the combustion of HFO unit in the electricity Dora station. They were divided into subgroups according to: their age, smoking habit, and the service period. Age and gender matched healthy individuals, (N=53) were also included in the study as a control group. Serum and saliva total oxidant status (TOS) and total antioxidant capacity (TAC) were measured using Erel's methods and OSI was calculated. Serum (TOS) and (OSI) levels were found to be higher (p-value <0.000) in the workers than in controls with a reduced levels of antioxidants (p-value <0.05) in these workers.

“…The principle of immune work in the oral cavity is to induce cellular immune responses and humoral immune responses in the oral cavity to prevent the formation of dental plaque and colonization of Streptococcus mutans. 6 In accordance with the DMF-T index study and caries prevalence in the western district of Bandung, high natural radiation due to limestone and granite are 4.38 and 86% and so on the Mount Masigit and 5.94 and 98% in the village of Cipatat village. 9 DMF-S research index in these two villages is categorized as medium.10 Natural environmental radiation factors are suspected to be factors vital supporters who can improve the cause of the health of dental and mouth status.…”

Introduction: Environment and behaviour are the main factors affecting the health status of a human being. People living in high natural radiation exposure area (radon zone), which is as much as 85% of the air content, characterized by many presents of granite rocks. The village of Arjasari is an area with many granite rocks presence. The objective of this study was to determined the knowledge level of the elementary school students after education regarding natural background radiation and oral health care. Methods: The research was a descriptive survey research, with data sampling taken by using questionnaires towards as much as 150 elementary students. Previously, respondents were given first education regarding natural background radiation and oral health care. Instruments in this study using questionnaires that was tested for validation and reliabilities. Data analysis used was a descriptive survey technique processed by using computer program. Data was percentages of three rating categories, which were high, medium and low. Results: The results showed that the knowledge level of student regarding natural background radiation and oral health care. was as much as 14% in the high category; as much as 45% in the moderate category; and as much as 41% in the low category. Conclusion: Knowledge level of student after education about natural radiation and the effect of oral health was in the moderate category level.
