Diabetes comorbidities include disabling peripheral neuropathy (DPN) and an increased risk of developing cancer. Antimitotic drugs, such as paclitaxel, are well known to facilitate the occurrence of peripheral neuropathy. Practitioners frequently observe the development or co-occurrence of enhanced DPN, especially cold sensitivity, in diabetic patients(More)
A phenotypic feature of aging is skeletal muscle wasting. It is characterized by a loss of muscle mass and strength. Age-related loss of muscle mass occurs through a reduction in the rate of protein synthesis, an increase in protein degradation or a combination of both. However, the underlying mechanism is still poorly understood. To test the hypothesis(More)
Immune cell infiltration of expanding adipose tissue during obesity and its role in insulin resistance has been described and involves chemokines. However, studies so far have focused on a single chemokine or its receptor (especially CCL2 and CCL5) whereas redundant functions of chemokines have been described. The objective of this work was to explore the(More)
Obesity and aging are characterized by decreased insulin sensitivity (IS) and muscle protein synthesis. Intramuscular ceramide accumulation has been implicated in insulin resistance during obesity. We aimed to measure IS, muscle ceramide level, protein synthesis, and activation of intracellular signaling pathways involved in translation initiation in male(More)
Post-translational oxidative protein modifications which are more marked during aging and/or high-calorie (HC) diets affect protein function and metabolism. Protein function and metabolism are different according to the type of muscle proteins. Oxidative muscle protein modifications may thus be associated with age-related sarcopenia, and HC may be(More)
Epidemiological studies suggest that chronic consumption of trans MUFA may alter muscle insulin sensitivity. The major sources of dietary trans MUFA (dairy fat vs. industrially hydrogenated oils) have different isomeric profiles and thus probably different metabolic consequences. These effects may involve alterations in muscle mitochondrial oxidative(More)
BACKGROUND The diminished ability of aged muscle to self-repair is a factor behind sarcopenia and contributes to muscle atrophy. Muscle repair depends on satellite cells whose pool size is diminished with aging. A reduction in Notch pathway activity may explain the age-related decrease in satellite cell proliferation, as this pathway has been implicated in(More)
Adiponectin is an adipocyte-derived adipokine with potent antidiabetic, anti-inflammatory, and antiatherogenic activity. Long-term, high-fat diet results in gain of body weight, adiposity, further inflammatory-based cardiovascular diseases, and reduced adiponectin secretion. Vitamin A derivatives/retinoids are involved in several of these processes, which(More)
Although the management of malnutrition is a priority in older people, this population shows a resistance to refeeding. Fresh bee pollen contains nutritional substances of interest for malnourished people. The aim was to evaluate the effect of fresh bee pollen supplementation on refeeding efficiency in old malnourished rats. Male 22-month-old Wistar rats(More)
