An infertile couple was referred for intracytoplasmic sperm injection (ICSI) because of primary infertility and oligoasthenoteratozoospermia (OAT) in the male. It was observed that although the sperm cells presented with an unusual head size and multiple tails they were able to fertilize the oocytes after ICSI. Subsequent molecular cytogenetic analysis demonstrated de-novo chromosome abnormalit...

The problem of time-dependent particle transport in quantum conductors is nowadays a well established topic. In contrast, the way in which energy and heat flow in mesoscopic systems subjected to dynamical drivings is a relatively new subject that cross-fertilize both fundamental developments of quantum thermodynamics and practical applications in nanoelectronics and quantum information. In this...

Treated wastewater (TWW) reuse for crop irrigation has been developing in recent decades areas hampered by severe water shortages. However, humid conditions, the agronomic impacts of supplementary are less and poorly documented. On island Réunion, we measured sugarcane yield quality on a Nitisol over 2 years providing 2600 mm TWW or (control) as supplement to 3500 rainfall. Meanwhile, with same...

The present study was conducted to detect sperm apoptosis in fresh, capacitated and frozen ram semen and to determine its relationship with other seminal parameters as motility and viability. The cryopreservation process induces the plasma membrane disruptions, attended with increasing of phoshpatidylserine molecules expression on the extracellular surface, wherefore some of the live spermatozo...

http://dx.doi.org/10.1016/j.chempr.2017.01.012 The first record of hand pollination was in a relief from an Assyrian dynasty, 800 BC, now preserved in the Boston Museum of Fine Arts. In the relief, shown in Figure 1A, two winged deities gingerly fertilize a date palm tree by using a male flower. Nearly 3,000 years later, pollination has been automated. In this issue of Chem, Chechetka et al. de...

  SUMMARY This study was conducted to shed light on to the factors contributing to fertilizing ability of the caput epididymal spermatozoa. In this content, it should be stated that seminal plasma am! epididymal fluid of most mammalians contains inhibitory factors connected to spermatozoa surface. To do this, components of different regions of mouse epididymis centrifuged and a given volume o...
