conclusions surgical wound infections are less common by using reusable retrieval bag during laparoscopic appendectomy procedure. also, using reusable retrieval bag has less cost. patients and methods one hundred twenty laparoscopic appendectomies performed over one year, were included in this retrospective study. the patients were divided into 2 group; group a was the one in which la was done ...

Introduction: Protein kinase M zeta (PKMζ) is assumed to be actively involved in retainig long-term potentiation. The goal of this study was to investigate the role of PKMζ in basolateral amygdala (BLA) upon acquisition, consolidation, retention and retrieval of memory using a specific inhibitor of PKMζ. Methods: Sixty male wistar rats underwent stereotaxic surgery and were cannu...

purpose previous studies have shown that physical activity improves learning and memory. present study was performed to determine the effects of short term and long term treadmill exercise on learning, memory consolidation and retrieval of passive avoidance learning in an animal model. methods in this study fifty male wistar rats with 3-4 months of age were randomly divided into five groups (n=...

background: the most expensive variable in the operating room (or) is time. lean process management is being used in the medical field to improve efficiency in the or. streamlining individual processes within the or is crucial to a comprehensive time saving and cost-cutting health care strategy. at our institution, one hour of or time costs approximately $500, exclusive of supply and personnel ...

the aim of the present study was to investigate whether and by which mechanism; histamine can induce state-dependent retrieval of passive avoidance task. the pre-training or pre-test intracerebroventricular (i.c.v.) injection of histamine (20µg/mouse) impaired retrieval, when it was tested 24 h later. in the animals, which retrieval was impaired due to histamine pre-training administration, pre...

with the increase of the volume of information and the progress in technology, the deficiency of traditional algorithms for fast information retrieval becomes more clear. when large volumes of data are to be handled, the use of neural network as an artificial intelligent technique is a suitable method to increase the information retrieval speed. neural networks present a suitable representation...

during endodontic treatment, clinicians may face endodontic procedural mishaps such as broken instruments, which is a complex situation especially when the file breaks beyond the apex. this condition is associated with potential risk of contamination, which compromises the healing process. management of a broken instrument beyond the apex is difficult and time consuming and requires creativity ...
