Besides its well-known regulatory role on circadian rhythm, the pineal gland hormone melatonin has other biological functions and a distinct metabolism in various cell types and peripheral tissues. In different tissues and organs, melatonin has been described to act as a paracrine and also as an intracrine and autocrine agent with overall homeostatic(More)
Oxidative stress has been implicated in mechanisms leading to neuronal cell injury in various pathological states of the brain. Alzheimer’s disease (AD) is a progressive disorder with cognitive and memory decline, speech loss, personality changes and synapse loss. Many approaches have been undertaken to understand AD, but the heterogeneity of the etiologic(More)
Cystic fibrosis is a lethal autosomal recessive condition caused by a defect of the transmembrane conductance regulator gene that has a key role in cell homeostasis. A dysfunctional cystic fibrosis transmembrane conductance regulator impairs the efflux of cell anions such as chloride and bicarbonate, and also that of other solutes such as reduced(More)
BACKGROUND Surgical operations which shorten the intestinal tract between the stomach and the terminal ileum result in an early improvement in type 2 diabetes, and one possible explanation is the arrival of undigested food in the terminal ileum. This study was designed to evaluate the role of the distal ileum in the improvement of glucose control in type 2(More)
BACKGROUND The present study was designed to test the biocompatibility of a new vitamin E-modified multi-layer membrane (CL-E filter), as well as its ability to protect against oxygen free radicals during hemodialysis (HD). METHODS We investigated, both in vitro and in vivo, the bioreactivity of the filter with respect to the blood antioxidants and its(More)
(5aS,8S,10aR)-5a,6,9,10-Tetrahydro,7H,11H-8,10a-methanopyrido[2',3':5,6]pyrano[2,3-d]azepine (SSR591813) is a novel compound that binds with high affinity to the rat and human alpha4beta2 nicotinic acetylcholine receptor (nAChR) subtypes (Ki = 107 and 36 nM, respectively) and displays selectivity for the alpha4beta2 nAChR (Ki, human alpha3beta4 > 1000,(More)
Oxidative response and inflammation constitute a major defense against infections, but if not properly regulated they could also lead to a number of deleterious effects. Patients affected by different stages of acute and chronic kidney disease, particularly patients on hemodialysis, present a marked activation of oxidative and inflammatory processes. This(More)
BACKGROUND It has been hypothesized that glucagon-like peptide-1 (GLP-1), secreted by ileal L cells, plays a key-role in the resolution of type 2 diabetes after bariatric operations whose common feature is an expedite nutrient delivery to the hindgut. Ileal transposition (IT), an operation that permits L-cell stimulation by undigested food, was employed to(More)
Oxidative stress, a hallmark of Alzheimer disease (AD), has been shown to induce lipid peroxidation and apoptosis disrupting cellular homeostasis. Normally, the aminophospholipid phosphatidylserine (PtdSer) is asymmetrically distributed on the cytosolic leaflet of the lipid bilayer. Under oxidative stress conditions, asymmetry is altered, characterized by(More)
The presence of high molecular weight toxins in the uraemic blood had largely been ignored until the beginning of the era of proteomics. In the last decade, increasing interest focused on these solutes has yielded evidence to suggest that some of these proteinaceous uraemic compounds can play pathogenic roles in the inflammatory and vascular comorbidities(More)
