Abstract

Background and objectives:

most common causes of morbidity and mortality in industrial and

developing countries. Recent studies have suggested that

Helicobacter pylori

heart disease therefore, this study was carried out in Gorgan, Iran, to

show the relationship between coronary disease and Helicobacter

pylori infection.

Materials and Methods:

carried out on 109 patients suffering from acute coronary syndrome

and 85 healthy individuals, ELISA was used to determine Anti

Helicobacter pylori Anti bodies (IgA, IgG ).

Results:

while in control group were %32.9 and %62.4. There was significant

difference between IgA of two groups (p<0.007). Simultaneous

presence of both IgG and IgA in patients affected by Coronary disease

was meaningful (p<0.003).

Conclusion

be related to coronary disease, we suggest their investigation in

suspected individuals.

ABSTRACT
Background and Objectives: Exercise is a strong physiological stimulus that can affect apoptosis in the lungs by altering a number of extracellular and intracellular signaling pathways. The present study examined effects of regular aerobic exercise and vitamin D on expression of Bcl-2, Bax and caspase-3 in lung tissues of male rats exposed to hydrogen peroxide.
Methods: Forty-eight adult male Wistar rats were randomly assigned into six groups of eight, including 2 x H 2 O 2, 2H 2 O 2, Vit D (2HD), 2H2O2 + Regular Exercise Training (2HE), 2H2O2 + D3 + E (2HDE) ; Dimethyl sulfoxide (DMSO) and control (C). Subjects in the training groups performed aerobic exercise for eight weeks. Bax, Bcl-2, caspase-3 expression in the lung tissues was measured using RT-PCR.
Results: Bcl-2 expression in the exercise (P = 0.004) and vitamin D (P = 0.006) groups increased significantly compared to the control groups. Bax, Bcl-2 and caspase-3 expression was significantly lower in the exercise group and vitamin D supplementation group compared to the control group. On the other hand, concurrent exercise and vitamin D significantly reduce Bax expression but had no significant effect on Bcl-2 and caspase-3 expression.
Conclusion: Our results demonstrate that regular aerobic exercise along with vitamin D supplementation may play a role in reducing apoptosis in lungs following severe oxidative stress.

Background: Omentin-1 plays an important role in insulin function. Despite numerous studies, the effect of interval training on this adipokine is still vague. This study aimed to elucidate the effect of high-intensity interval training (HIIT) on serum glucose, insulin, insulin resistance (IR), omentin-1 serum levels, and gene expression in the visceral adipose tissue in type 2 diabetic (T2D) rats.
Methods: In an experimental study, 20 male rats (8-10 weeks, weight: 250-270 g) were randomly divided into 2 groups: diabetic control (N=10) and diabetic training (N=10). The training protocol was 30 minutes of HIIT (1-min run, 2-min rest) performed 5 days a week for 4 weeks. Fasting blood glucose, insulin resistance, omentin-1 serum level, and gene expression were measured in the visceral fat 48 hours after the last exercise for both groups.
Results: The HIIT resulted in lower serum glucose and insulin resistance (P = 0.001), higher serum omentin-1 levels (P = 0.001), and higher visceral fat gene expression (P = 0.004) in the training group compared to the control group.
Conclusion: Lower serum glucose and insulin resistance and higher omentin-1 serum levels and gene expression in the training group can prove the effectiveness of HIIT training in T2D, although further research is required.
