Publikováno v: Andrology. 4:808-815

The influence of seminal leukocytes on generation of oxidative damage to sperm DNA was here investigated on male partners of subfertile couples asymptomatic for a genital tract infection. The study included 111 ejaculates from men attending the Andro

Association between 25(OH)-vitamin D and testosterone levels: Evidence from men with chronic spinal cord injury

Autor: Felice Francavilla, Sandro Francavilla, Giorgio Felzani, Arcangelo Barbonetti, M. R. C. Vassallo

Publikováno v: Europe PubMed Central

As an independent linear association between 25-hydroxyvitamin D (25(OH)D) and testosterone levels is controversial, this study aimed to explore this topic in men with chronic spinal cord injury (SCI), who exhibit a high prevalence of both androgen a

Low testosterone and non-alcoholic fatty liver disease: Evidence for their independent association in men with chronic spinal cord injury

Autor: Felice Francavilla, Arcangelo Barbonetti, Giorgio Felzani, M. R. C. Vassallo, Michele Cotugno, Sandro Francavilla

Non-alcoholic fatty liver disease (NAFLD) has been claimed as a liver phenotype of metabolic syndrome, which in turn is associated with male hypogonadism. We assessed whether an independent association between NAFLD and androgen deficiency could be r

Energetic Metabolism and Human Sperm Motility: Impact of CB1 Receptor Activation

Autor: Arcangelo Barbonetti, Mauro Maccarrone, M. R. C. Vassallo, Sandro Francavilla, D. Fortunato, Felice Francavilla

Publikováno v: Endocrinology. 151:5882-5892

It has been reported that the endocannabinoid anandamide (AEA) exerts an adverse effect on human sperm motility, which has been ascribed to inhibition of mitochondrial activity. This seems to be at variance with evidence suggesting a major role of gl

Publikováno v: Biology of Reproduction. 79:649-656

Phosphorylation of tyrosine residues in cellular proteins represents a major event during sperm capacitaton, but its relationship with the acquisition of sperm-fertilizing ability is still unclear. In this study we explored the relationship between t

Retinol binding protein 4, low birth weight-related insulin resistance and hormonal contraception

Autor: Felice Francavilla, Maria Simonetta Colangeli, Arcangelo Barbonetti, Stefano Necozione, C. Pandolfi, Anatolia D’Angeli, Antonella Zugaro, Sandro Francavilla, M. R. C. Vassallo

Publikováno v: Endocrine. 32:166-169

It has been recently reported that increased serum levels of retinol binding protein 4 (RBP4), a molecule secreted by adipocytes and liver, could be an early marker of insulin resistance (IR). We determined whether serum RBP4 was increased in low bir

Publikováno v: Andrology. 2(5)

Summary Although high rates of serum testosterone deficiency have been reported in men with spinal cord injury (SCI), its determinants and attributes are not yet established. The aim of this study was to recognize, among putative determinants and att

Involvement of cannabinoid receptor-1 activation in mitochondrial depolarizing effect of lipopolysaccharide in human spermatozoa

Autor: Mauro Maccarrone, Felice Francavilla, Arcangelo Barbonetti, Natalia Battista, Sandro Francavilla, M. R. C. Vassallo, M. Costanzo

Gram-negative bacteria frequently involved in urogenital tract infections release the endotoxin lipopolysaccharide (LPS); its receptor, toll-like receptor-4 (TLR4), has been recently identified in human spermatozoa, and its direct activation has been
