Low-power density of 950 MHz radiation does not affect long-term potentiation in rat dentate gyrus
Introduction: Over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. This in vivo study was planned for evaluating the effects of whole-body exposure to 950 MHz field of GSM mobile phone system on rat dentate gyrus long-term potentiation. Materials and Methods: 24 naive male Wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...
متن کاملPancreatic ductal adenocarcinoma: long-term survival does not equal cure.
BACKGROUND Pancreatic ductal adenocarcinoma represents 90% of pancreatic cancers and is an important cause of cancer death in the United States. Operative resection remains as the only treatment providing prolonged survival, but even after a curative resection, 5-year survival rates are low. Our aim was to identify the prognostic factors for long-term survival after resection of pancreatic duct...

OBJECTIVE To achieve maximum post-thaw survival of frozen embryos. DESIGN Historical controlled study. SETTING Hospital-based fertility center. PATIENT(S) One hundred forty-five patients whose embryos were frozen and thawed according to the standard method, and 56 patients whose embryos were frozen and thawed according to a modified method.

متن کاملLong-term cryostorage of sperm in a human sperm bank does not damage progressive motility concentration.
BACKGROUND The use of quarantined cryopreserved semen is mandatory in donor insemination programs. Whether sperm cells can survive and retain their ability to fertilize after long-term storage remains a controversial issue. The objective of this study was to determine the effect of the duration of cryostorage in liquid nitrogen on the sperm cells' progressive motility concentration (PMC) in a l...
