Fourier transform infrared analysis of urinary calculi and metabolic studies in a group of Sicilian children

2017

Introduction. Prevalence of urinary calculi in children has been increasing in the past years. We performed an analysis of the chemical composition of stones formers of the pediatric population in our geographical area over the years 2005 to 2013. Materials and Methods. Fourier transform infrared spectroscopy was employed for the determination of the calculus composition of a group of Sicilian children, and metabolic studies were performed to formulate the correct diagnosis and establish therapy. Results. The prevalence of stone formation was much higher for boys than for girls, with a sex ratio of 1.9:1. The single most frequent component was found to be calcium oxalate monohydrate, and ca…

Role of chronic exposure to cigarette smoke on endoglin/CD105 expression in airway epithelium

2015

Dysregulation of airway epithelium function related to cigarette smoke exposure plays an important role in the pathophysiology of COPD and is associated to tissue damage and disease severity. CD105 is a component of the receptor complex of TGF-β, a pleiotropic cytokine involved in cellular proliferation, differentiation and migration. CD105 regulates the expression of different components of the extracellular matrix suggesting a role of CD105 in cellular transmigration and remodeling processes. The aim of the present study was to investigate the expression of endoglin/CD105 in airway epithelium of COPD patients and its involvement in tissue remodeling and COPD progression. We evaluated the …

Metabolomic analysis of plasma from Alzheimer disease patients

2011

Alzheimer Disease is a degenerative disease characterized by progressive impairment of cognitive function. The main feature of AD the generation of an abnormal peptide, beta amyloid 42 (Ab42) from Amyloid Precursor Protein (APP). Ab42 is the main constituent of neurotangles and amyloid plaques, microscopic lesions found in AD patients brain. Ab42 triggers an inflammatory response that is responsible for most of the observed tissue damage. The diagnosis of AD is a complex task, mostly based on imaging techniques and clinical evaluation of the patient’s neurological and cognitive functions. The search for plasma biomarkers able to detect early mild cognitive impairment is one of the recent at…

Role of chronic exsposure to cigarette smoke on endoglin/CD105 expression in airway epithelium.

Dysregulation of airway epithelial cell function related to cigarette smoke exposure plays an important role in the pathophysiology of COPD and is associated to tissue damage and disease severity. CD105 is a component of the receptor complex of TGF-β, a pleiotropic cytokine involved in cellular proliferation, differentiation and migration. CD105 regulates the expression of different components of the extracellular matrix suggesting a role of CD105 in cellular transmigration and remodeling processes.
