background: we investigated the effects of withania somnifera root (ws) on insulin resistance, tumor necrosis factor α (tnf-α), and interleukin-6 (il-6) in fructose-fed rats. methods: forty-eight wistar-albino male rats were randomly divided into four groups (n=12); group i as control, group ii as sham-treated with ws by 62.5mg/g per diet, group iii fructose-fed rats received 10%w/v fructose, a...

Jerusalem artichoke (JA) has the potential to attenuate lipid disturbances and insulin resistance (IR), but the underlying mechanisms are not well understood. In the present study, we elucidated the physiological responses and mechanisms of JA intervention with a comprehensive transcriptome analysis. Wistar rats were fed a control diet, a 60 % fructose-enriched diet (FRU), or a FRU with 10 % JA...

Fructose consumption in the USA has increased over the past three decades. During this time, obesity, insulin resistance and the metabolic syndrome have also increased in prevalence. While diets high in fructose have been shown to promote insulin resistance and increase TAG concentrations in animals, there are insufficient data available regarding the long-term metabolic effects of fructose con...

There has been much concern regarding the role of dietary fructose in the development of metabolic diseases. This concern arises from the continuous increase in fructose (and total added caloric sweeteners consumption) in recent decades, and from the increased use of high-fructose corn syrup (HFCS) as a sweetener. A large body of evidence shows that a high-fructose diet leads to the development...

1. Male and female baboons were fed a 75% sucroselfat free diet for 13 weeks. At the end of this period, and when tested by a sucrose meal, the glucose tolerance was improved, but the fructose tolerance impaired. 2. There was no difference between the male and female baboons with regard to the changes observed in glucose tolerance. The impairment of fructose tolerance as a result of the sucrose...

OBJECTIVE The aim of this study was to determine the effects of rilmenidine (an antihypertensive drug that lowers blood pressure by decreasing sympathetic outflow) in an animal model of hypertension associated with insulin resistance, i.e. rats fed on a high-fructose diet. DESIGN Wistar rats were fed for 4 weeks either on a standard diet (S group) or on a high-fructose diet (F group; 34.5% fr...

Nonenzymatic glycation of proteins, leading to chemical modification and cross-linking are of importance in the pathology of diabetic complications. We studied the effect alpha-lipoic acid (LA) on the content and characteristics of the protein collagen from skin of high-fructose fed rats. The rats were divided into 4 groups of 6 each. Two groups of rats were fed with a high fructose diet (60 g/...
