Pollution exposure and high DNA fragmentation index in human sperms: a case-control study
2016
Study question: Could pollution exposure play a key role on sperm quality, in terms of DNA fragmentation index (DFI)? Summary answer: Patients exposed to high level of pollution show an higher percentage of sperm DNA fragmentation index in contrast with patient from control group. What is known already: Taranto area is characterized by a number of steel factories and petrochemical industries. Data about the detrimental effects of environmental pollution are alarming. Pollution coming from the industrial plants causes health and fertility risks, mainly due to the exposure to several pollutant (PM10, heavy metals, etc). Toxic substances can affect DNA directly or indirectly, through oxidative…

2012
Introduction: In the last decades sperm DNA quality has been recognized as one of the most important markers of male reproductive potential (Lewis and Aitken, 2005; Ozmen, 2007; Tarozzi, 2007), in contrast to standard semen parameters as sperm density, motility and morphology, which do not act as powerful discriminators between fertile and infertile men. DNA damage in the male germ line is a major contributor to infertility, miscarriage and birth defects in the offspring. In animal models, it has been unequivocally demonstrated that the genetic integrity of the male germ line plays a major role in determining the normality of embryonic development. In humans, many studies showed that sperm …
Functional and dysfunctional isoforms of human neuroserpin
2015
Neuroserpin (NS) is a serine protease inhibitor (SERPIN) involved in different neurological pathologies, including the Familial Encephalopathy with Neuroserpin Inclusion Bodies (FENIB), related to the aberrant polymerization of NS mutants. Here we present an in vitro and in silico characterization of native NS and its dysfunctional conformation isoforms: the proteolytically cleaved conformer, the inactive latent conformer, and the polymeric conformer. Using circular dichroism and fluorescence spectroscopy, we present an experimental validation of the latent model and highlight the main structural features of the different conformers. In par- ticular, emission spectra of aromatic residues yi…
