Fluorescence ratiometric properties induced by nanoparticle plasmonics and nanoscale dye dynamics.
ScientificWorldJournal 2013 , 624505, (2013) Nanoscale transport of merocyanine 540 within/near the plasmon field of gold nanoparticles was recognized as an effective inducer of single-excitation dual-emission ratiometric properties. With a high concentration of the signal transducer (ammonium), a 700% ... |

Acrosin activity is a good predictor of boar sperm freezability.
Theriogenology 83 , 1525-33, (2015) The main aim of this study was to determine whether acrosin activity could predict boar sperm freezability. For this purpose, we characterized the changes in sperm quality and acrosin activity throughout the cryopreservation procedure of sperm samples from 30... |

B cell development in the spleen takes place in discrete steps and is determined by the quality of B cell receptor-derived signals.
J. Exp. Med. 190 , 75-89, (1999) Only mature B lymphocytes can enter the lymphoid follicles of spleen and lymph nodes and thus efficiently participate in the immune response. Mature, long-lived B lymphocytes derive from short-lived precursors generated in the bone marrow. We show that select... |

Detrimental effects of non-functional spermatozoa on the freezability of functional spermatozoa from boar ejaculate.
PLoS ONE 7 , e36550, (2012) In the present study, the impact of non-functional spermatozoa on the cryopreservation success of functional boar spermatozoa was evaluated. Fifteen sperm-rich ejaculate fractions collected from five fertile boars were frozen with different proportions of ind... |

The Effect of Sperm Concentration and Storage Vessel on Quercetin-Supplemented Rabbit Semen During Chilled Storage.
Reprod. Domest. Anim. 50 , 567-73, (2015) Extending the shelf life of chilled rabbit spermatozoa is vital for the expansion of the farmed rabbit industry. This study evaluated the relationship between sperm concentration and packaging on in vitro quality of chilled rabbit semen over 96 h. Semen was c... |

Heat Shock Protein member A2 forms a stable complex with angiotensin converting enzyme and protein disulfide isomerase A6 in human spermatozoa.
Mol. Hum. Reprod. 22 , 93-109, (2016) Given the importance of the chaperone Heat Shock Protein A2 (HSPA2) in the regulation of male fertility, this study aimed to identify and characterize additional proteins that may rely on the activity of this chaperone in human spermatozoa.In view of the find... |

Penicillamine prevents ram sperm agglutination in media that support capacitation.
Reproduction 151 , 167-77, (2015) Ram spermatozoa are difficult to capacitate in vitro. Here we describe a further complication, the unreported phenomenon of head-to-head agglutination of ram spermatozoa following dilution in the capacitation medium Tyrodes plus albumin, lactate and pyruvate ... |

Effect of different media additives on capacitation of frozen-thawed ram spermatozoa as a potential replacement for estrous sheep serum.
Theriogenology 84 , 948-55, (2015) Capacitation is a key process through which spermatozoa acquire their fertilizing ability. This event is required for the successful application of assisted reproductive technologies such as IVF. The aim of the present study was to investigate the effect of u... |

The role of zinc in the modulation of neuronal proliferation and apoptosis.
Neurotox. Res. 17 , 1-14, (2009) Although a requirement of zinc (Zn) for normal brain development is well documented, the extent to which Zn can modulate neuronal proliferation and apoptosis is not clear. Thus, we investigated the role of Zn in the regulation of these two critical events. A ... |

Ionomycin causes susceptibility to phospholipase A2 while temperature-induced increases in membrane fluidity fail: possible involvement of actin fragmentation.
Biochim. Biophys. Acta 1838(10) , 2607-14, (2014) A diminution in the order of membrane lipids, which occurs during apoptosis, has been shown to correlate with increased membrane susceptibility to hydrolysis by secretory phospholipase A2. Studies with artificial membranes, however, have demonstrated that the... |
