Long-term vegetarians have low oxidative stress, body fat, and cholesterol levels

Excessive oxidative stress and abnormal blood lipids may cause chronic diseases. This risk can be reduced by consuming an antioxidant- and fiber-rich vegetarian diet. We compared biomarkers of oxidative stress, antioxidant capacity, and lipid profiles of sex- and age-matched long-term vegetarians and omnivores in Korea. Forty-five vegetarians (23 men and 22 women; mean age, 49.5 ± 5.3 years), who had maintained a vegetarian diet for a minimum of 15 years, and 30 omnivores (15 men and 15 women; mean age, 48.9 ± 3.6 years) participated in this study. Their 1-day, 24-h recall, and 2-day dietary records were analyzed. Oxidative stress was measured by the levels of diacron reactive oxygen metabolites (d-ROM). Antioxidant status was determined by the biological antioxidant potential (BAP) and levels of endogenous antioxidant enzymes such as superoxide dismutase, catalase, and glutathione peroxidase. We observed that vegetarians had a significantly lower body fat percentage (21.6 ± 6.4%) than that of omnivores (25.4 ± 4.6%; P < 0.004). d-ROM levels were significantly lower in vegetarians than those in omnivores (331.82 ± 77.96 and 375.80 ± 67.26 Carratelli units; P < 0.011). Additionally, total cholesterol levels in the vegetarians and omnivores were 173.73 ± 31.42 mg/dL and 193.17 ± 37.89 mg/dL, respectively (P < 0.018). Low-density lipoprotein cholesterol was 101.36 ± 23.57 mg/dL and 120.60 ± 34.62 mg/dL (P < 0.005) in the vegetarians and omnivores, respectively, indicating that vegetarians had significantly lower lipid levels. Thus, oxidative stress, body fat, and cholesterol levels were lower in long-term vegetarians than those in omnivores.     

Sonoelastography findings of biceps tendinitis and tendinosis

Objective

The purpose of this study was to evaluate sonoelastography (SE) in the assessment of the long head of biceps tendon (LHBT) in patients with symptoms of biceps tendinitis or tendinosis and in patients without biceps lesion. The findings were compared with those obtained at clinical examination, using ultrasonography (US).

Materials and methods

36 shoulders of 34 consecutively registered patients with clinical symptoms and US findings of biceps tendinitis or tendinosis, and 114 shoulders of 98 patients without biceps lesions were assessed with SE. Transverse and longitudinal images of LHBT were obtained using SE. SE images were evaluated by reviewers using an experimentally proven color grading system.

Results

The transverse images of SE showed a mean sensitivity of 69.4 %, a mean specificity of 95.6 % and a mean accuracy of 89.3 %. Good correlation of conventional ultrasound findings was found (p < 0.001, r = 0.763). The longitudinal images of SE showed a mean sensitivity of 94.4 %, a mean specificity of 92.1 % and a mean accuracy of 92.7 %. Good correlation of conventional ultrasound findings was found (p < 0.001, r = 0.585). Inter-observer reliability of SE was in “almost perfect agreement” with a weighted kappa coefficient of 0.84.

Conclusions

SE has potential to be clinically useful in the detection of the intratendinous and peritendinous alterations of LHBT and has excellent accuracy and excellent correlation with conventional ultrasound findings.     

Hypermethylation of repetitive DNA elements in livers of mice fed an atherogenic diet

ObjectiveDNA methylation status was examined in C57BL/6J obese mice fed an atherogenic diet (AD) to establish the correlation between epigenetic alterations and obesity-related abnormalities.MethodsSix-week-old male C57BL/6J mice were fed a normal diet (ND) or AD for 8 wk. Methylation levels of global DNA and repetitive DNA elements in livers of ND-fed mice and AD-fed mice were examined.ResultsThe total amounts of 5-MeC genomic contents in livers of AD-fed mice were increased as compared with those of ND-fed mice. Hypermethylation of repetitive DNA elements was observed in livers of AD-fed mice.ConclusionHypermethylation of repetitive DNA elements in livers of AD-fed mice proposes epigenetic changes by nutritional intervention.
