The metabolic syndrome MS recognized as a major cause of type 2 diabetes and cardiovascular diseases, has become one of the major public health challenges worldwide. The pathogenesis of the metabolic syndrome is multiple and still poorly understood.

Ferreira 6. Metabolic syndrome MetS has a high prevalence around the world. Considering the components used to classify MetS, it is clear that it is closely related to obesity.

Biomarkers of Oxidative Stress in Metabolic Syndrome and Associated Diseases

Obesity is a principal causative factor in the development of metabolic syndrome. Here we report that increased oxidative stress in accumulated fat is an important pathogenic mechanism of obesity-associated metabolic syndrome. Fat accumulation correlated with systemic oxidative stress in humans and mice.

Production of ROS increased selectively in adipose tissue of obese mice, accompanied by augmented expression of NADPH oxidase and decreased expression of antioxidative enzymes. In cultured adipocytes, elevated levels of fatty acids increased oxidative stress via NADPH oxidase activation, and oxidative stress caused dysregulated production of adipocytokines fat-derived hormones , including adiponectin, plasminogen activator inhibitor—1, IL-6, and monocyte chemotactic protein—1.

Finally, in obese mice, treatment with NADPH oxidase inhibitor reduced ROS production in adipose tissue, attenuated the dysregulation of adipocytokines, and improved diabetes, hyperlipidemia, and hepatic steatosis. Collectively, our results suggest that increased oxidative stress in accumulated fat is an early instigator of metabolic syndrome and that the redox state in adipose tissue is a potentially useful therapeutic target for obesity-associated metabolic syndrome.

Previous evidence supports the important role that oxidative stress OxS plays in metabolic syndrome MetS -related manifestations. IRH and total nitrite levels were higher in subjects with 2 or 3 MetS components than subjects with 4 or 5 MetS components.

There is some evidence that suggest a higher dietary total antioxidant capacity DTAC is associated with a lower risk of metabolic syndrome MetS. Considering the conflicting results in this field, this paper aims to provide a comprehensive summary of studies on the association of DTAC and components of MetS. A systematic review of articles indexed in PubMed, Scopus and Google Scholar, published from inception to September , with defined keywords, was done. Duplicate or irrelevant reports were screened out and data were extracted through critical analysis. Finally, among the articles, 19 articles met the inclusion criteria.


Oxidative stress is associated with many of the components of the syndrome, leading to the concept that the amelioration of risk factors comprising metabolic syndrome, including insulin resistance, elevated blood pressure, elevated lipid levels, inflammation and endothelial dysfunction may ameliorate oxidative stress.


Role of oxidative stress in pathogenesis of metabolic syndrome

Metabolic syndrome MS represents worldwide public health issue characterized by a set of cardiovascular risk factors including obesity, diabetes, dyslipidemia, hypertension, and impaired glucose tolerance. The link between the MS and the associated diseases is represented by oxidative stress OS and by the intracellular redox imbalance, both caused by the persistence of chronic inflammatory conditions that characterize MS. The increase in oxidizing species formation in MS has been accepted as a major underlying mechanism for mitochondrial dysfunction, accumulation of protein and lipid oxidation products, and impairment of the antioxidant systems.

There is increasing evidence of the prevalence manifestations of metabolic syndrome worldwide. Metabolic syndrome is a cluster of abnormalities characterized by hypertension, central obesity, insulin resistance, endothelial dysfunction, dyslipidemia and oxidative stress. All these alterations predispose individuals to type 2 diabetes and cardiovascular disease that are major contributing factors to earlier mortality among people. The investigation of food nutrients that could reverse the features of metabolic syndrome is an important aspect for dietary-based therapies that may ameliorate the burden of the disorder. Antioxidant micronutrients are of great interest due to the recent described association between obesity, cardiovascular alterations and oxidative stress.

Metabolic syndrome MS represents a cluster of physiological and anthropometric abnormalities. The purpose of this study was to investigate the relationships between the levels of inflammation, adiponectin, and oxidative stress in subjects with MS. The levels of inflammatory markers [high sensitivity C-reactive protein hs-CRP and interleukin-6 IL-6 , adiponectin, an oxidative stress marker malondialdehyde , and antioxidant enzymes activities [catalase CAT , superoxide dismutase SOD , and glutathione peroxidase GPx ] were measured. Subjects with MS had significantly higher concentrations of inflammatory markers and lower adiponectin level, and lower antioxidant enzymes activities than the control subjects. The levels of inflammatory markers and adiponectin were significantly correlated with the components of MS.

As antioxidants play a protective role in the pathophysiology of diabetes and cardiovascular diseases, understanding the physiological status of antioxidant concentration among people at high risk for developing these conditions, such as Metabolic Syndrome, is of interest. In present study out of first degree non-diabetic relatives and non-diabetic spouses,

Does total antioxidant capacity affect the features of metabolic syndrome? A systematic review

Самый крупный мужчина из всех, с кем ей приходилось иметь. Нарочито медленно она взяла из ведерка кубик льда и начала тереть им соски. Они сразу же затвердели. Это было одной из ее многочисленных хитростей: мужчинам казалось, что она сгорает от страсти, поэтому они стремились прийти к ней снова и. Росио погладила руками свои пышные загорелые формы - дай Бог, чтобы они сохраняли свою привлекательность еще лет пять-шесть, пока она не накопит достаточно денег. Сеньор Ролдан забирал большую часть ее заработка себе, но без него ей пришлось бы присоединиться к бесчисленным шлюхам, что пытаются подцепить пьяных туристов в Триане.

Эти письма в моем компьютере скопированы с терминала Стратмора - это сообщения, которые КОМИНТ выкрал у Танкадо. - Чепуха. Ты никогда не смог бы проникнуть в почту коммандера. - Ты ничего не понимаешь! - кричал Хейл.  - На его компьютере уже стоял жучок! - Он говорил, стараясь, чтобы его слова были слышны между сигналами.

Потом закрыл глаза и глубоко вздохнул. Беккер не сразу почувствовал, что его кто-то подталкивает. Подняв глаза, он увидел старика с усыпанным родинками лицом, который стоял перед ним, намереваясь пройти. Беккера охватила паника. Он уже хочет уйти. Выходит, мне придется встать.

Сердце у Сьюзан бешено забилось. Правильно ли она поняла. Все сказанное было вполне в духе Грега Хейла. Но это невозможно.

 С вами хочет поговорить начальник шифровалки. Она сейчас будет. - Она? - Беккер рассмеялся. Он не заметил в АНБ ни одного существа женского пола.

Подобно своим природным аналогам они преследуют одну цель - внедриться в организм и начать размножаться. В данном случае организмом является ТРАНСТЕКСТ. Чатрукьяна всегда изумляло, что АНБ никогда прежде не сталкивалось с проблемой вирусов. Сквозь строй - надежная система, но ведь АНБ - ненасытный пожиратель информации, высасывающий ее из разнообразнейших источников по всему миру.

На противоположной стене висело распятие в натуральную величину. Беккер остановился. Тупик.

Глаза, которые еще не приобрели отсутствующего безжизненного взгляда, закатились вверх и уставились в потолок с застывшим в них выражением ужаса и печали. - Dоnde estan sus efectos? - спросил Беккер на беглом кастильском наречии.  - Где его вещи. - Alli, - ответил лейтенант с желтыми прокуренными зубами. Он показал на прилавок, где лежала одежда и другие личные вещи покойного.

И тут же забилась, задыхаясь от удушья. Ее снова сжали уже знакомые ей стальные руки, а ее голова была намертво прижата к груди Хейла. - Боль внизу нестерпима, - прошипел он ей на ухо. Колени у Сьюзан подкосились, и она увидела над головой кружащиеся звезды. ГЛАВА 80 Хейл, крепко сжимая шею Сьюзан, крикнул в темноту: - Коммандер, твоя подружка у меня в руках.

Стратмор приближался к ней, его лицо казалось далеким воспоминанием. Холодные серые глаза смотрели безжизненно. Живший в ее сознании герой умер, превратился в убийцу. Его руки внезапно снова потянулись к ней в отчаянном порыве.
