OBJECTIVE To estimate the effectiveness of gonadotropin-releasing hormone (GnRH) analogues cotreatment in preventing chemotherapy-induced amenorrhea in young breast cancer patients undergoing cyclophosphamide-based chemotherapy. METHODS One hundred hormone-insensitive breast cancer participants (aged 18-40 years) were recruited from two(More)
We study rheotaxis of bull sperm inside microchannels to characterize the effects of flow and wall shape on sperm swimming behavior. We found that a large percentage of sperm cells, 80 to 84%, exhibited positive rheotaxis (sperm cells swimming against the flow) within flow velocities of 33 to 134 μm s(-1). Sperm cells were also found to reverse their(More)
Digital microfluidics has become a popular tool for biochemical and biomedical applications. However, its current format is restricted to actuation of droplets on a single plane. Here, we introduce a new method for fluid handling on flexible devices, which we have termed all-terrain droplet actuation (ATDA). We show that ATDA can be used to manipulate(More)
A simple method to fabricate circular microchannels in polydimethylsiloxane (PDMS) is presented. A coating of liquid PDMS is applied on the walls of rectangular microchannels, fabricated using standard soft-lithography, by introducing a pressurized air stream inside the PDMS filled microchannels. Surface tension of the liquid PDMS forces the coating to take(More)
Role of the transforming growth factor-β1 (TGF-β1) gene polymorphisms located at codons 10 and 25 in the genetic predisposition to type 2 diabetes (T2D) and in diabetic nephropathy (DN) in Egyptian patients was investigated. A case control study was done for 99 unrelated Egyptian patients with T2D (50 DN(-) and 49 DN(+)) and 98 age- and sex-matched healthy(More)
Leak is the second most common cause of death after bariatric surgery. The leak rate after laparoscopic sleeve gastrectomy (LSG) ranges between 1.1 and 5.3 %. The aim of the paper is to provide an overview of the current pathogenic and promoting factors of leakage after LSG on the basis of recent literature review and to report the evidence based preventive(More)
Crural closure in addition to laparoscopic sleeve gastrectomy (LSG) represents a valuable option for the synchronous management of morbid obesity and hiatal defects, providing good outcomes in terms of weight loss and gastroesophageal reflux disease (GERD) symptoms control. The aim of this prospective study was to evaluate the safety and effectiveness of(More)
Bleeding and gastric fistula are the most common postoperative complications after laparoscopic sleeve gastrectomy (LSG). The long stapler line represents the most frequent source of bleeding, which ranges between 0 and 20%. The aim of this retrospective study was to analyze the 4-year experience of a high-volume center with respect to the prevention and(More)
