We tested the efficacy of coenzyme Q10 (ubidecarenone, CoQ10) therapy in patients with Kearns-Sayre syndrome and other mitochondrial myopathies with chronic progressive external ophthalmoplegia (CPEO). We treated seven patients for 1 year with daily oral administration of 120 mg of CoQ10. Throughout the treatment most of our patients showed a progressive(More)
We report biochemical, immunological, and morphological findings in a patient with fatal Kearns-Sayre syndrome. Histochemical and biochemical findings from muscle biopsy specimens obtained 7 years apart documented the disease's evolution from a mild mitochondrial disorder affecting a small proportion of muscle fibers to a severe disorder affecting a large(More)
Visceral adipose tissue-derived serpin (vaspin) improves glucose tolerance and insulin sensitivity in diet-induced obese mice. Chemerin may increase insulin sensitivity in adipose tissue and seems to be associated with several key aspects of metabolic syndrome. Decreased levels of omentin-1 are associated with increasing obesity and insulin resistance. Our(More)
In an open-label study, we substituted conventional levodopa plus benserazide: 100/25 (Madopar) with a controlled-release form (HBS) in 18 fluctuating parkinsonian patients for 24 months. Significantly positive results were obtained in both peak-dose and diphasic dyskinesias up to 12 months of treatment; morning akinesias were also improved up to 6 months.(More)
The objective of this study is to investigate relationship between migraine and cerebral infarction in young people. Patients aging 16–44 years, referred for stroke and age- and gender-matched controls were investigated for migraine following the International Headache Society criteria. Included people were 314 strokes and 314 controls. Each group consisted(More)
Peptide YY (1-36) and peptide YY (3-36) are gut-derived hormones which are involved in feeding control in the hypothalamus. The hypothalamic mechanisms of feeding have been shown to be modulated by aminergic neurotransmitters, which could mediate the anorectic or orexigenic effects of neuropeptides and hormones. We have investigated the role of peptide YY(More)
Glucagon-like peptide 1 (7-36) amide (GLP-1) and exendin-4 are gastrointestinal hormones as well as neuropeptides involved in glucose homeostasis and feeding regulation, both peripherally and at the central nervous system (CNS), acting through the same GLP-1 receptor. Aminergic neurotransmitters play a role in the modulation of feeding in the hypothalamus(More)
Obestatin is a gastric derived 23 amino acid peptide, which has shown anorectic effects in a number of experimental paradigms after both peripheral and central administration. On the other hand, several researchers were not able to confirm these data. Since all previous experiments have been performed in animals fed a standard laboratory diet, we studied(More)
Adiponectin (Adipocyte Complement-Related Protein of 30 kDa, ACRP30) and resistin are adipocyte-derived polypeptide hormones playing a role in metabolic homeostasis. Their plasma levels are inversely (adiponectin) or directly (resistin) correlated to obesity and they have opposite effects on insulin sensitivity. Adipose tissue hormones such as leptin have(More)
