Comprehensive effects of lifestyle reform, adherence, and related factors on hypertension control: A review.

Despite the effectiveness of currently available antihypertensive medications, there is still a need for new treatment strategies that are more effective in certain groups of hypertensive and for additional resources to combat hypertension. However, medication non-adherence was previously recognized as a major problem in the treatment of hypertension. The mechanisms behind the positive impacts of lifestyle changes might occur in different ways. In comparison with other studies, the efficacy and effectiveness of lifestyle modifications and antihypertensive pharmaceutical treatment for the prevention and control of hypertension and concomitant cardiovascular disease have been demonstrated in randomized controlled trials. However, in this review, the attitudinal lifestyle modifications and barriers to blood pressure control were elaborated on. An effective method for reducing blood pressure (BP) and preventing cardiovascular events with antihypertensive medications has been outlined. Maintaining healthy lifestyle factors (body mass index, diet, smoking, alcohol consumption, sodium excretion, and sedentary behavior) could lower systolic blood pressure BP by 3.5 mm Hg and reduce the risk of cardiovascular disease (CVD) by about 30%, regardless of genetic susceptibility to hypertension. Conducting a lifestyle intervention using health education could improve lifestyle factors, such as reducing salt, sodium, and fat intake, changing eating habits to include more fruits and vegetables, not smoking, consuming less alcohol, exercising regularly, maintaining healthy body weight, and minimizing stressful conditions. Each behavior could affect BP by modulating visceral fat accumulation, insulin resistance, the renin-angiotensin-aldosterone system, vascular endothelial function, oxidative stress, inflammation, and autonomic function. Evidence of the joint effect of antihypertensive medications and lifestyle reforms suggests a pathway to reduce hypertension.

Effects of iron-catalyzed oxidation and methemoglobin oxidation systems on endogenous enzyme activity and myofibrillar protein degradation in yak meat.

In this study, the effects of different oxidation intensities on the degradation of myofibrillar protein by endogenous enzymes in iron-catalyzed oxidizing (IOS) and metmyoglobin oxidizing system (MOS) were compared. The results showed that carbonyl content and endogenous enzyme activities (caspase-3, caspase-6 and calpain-1) increased significantly and the total sulfhydryl content decreased significantly with H2O2 concentration in both oxidation systems. Meanwhile, the rate of carbonyl formation and the inhibition of endogenous enzymes activities of IOS were significantly lower than MOS for the same oxidation intensity. In addition, IOS and MOS mainly produced myosin light chains degradation products of 20-25 kDa and 20-17 kDa. At the same oxidation intensity, MOS of myofibrillar protein significantly enhanced the degradation of troponin-T and desmin by caspase-3/-6 compared with IOS, while inhibiting the degradation of troponin-T by calpain-1. In conclusion, MOS inhibited endogenous enzyme degradation in vitro more than IOS during post-slaughter maturation of yak meat.
