The aim of this retrospective study was to examine the incidence and prognostic significance of abdominal wall metastases in patients with ovarian cancer present at the primary debulking at the entry sites of previous laparoscopy or paracentesis. The clinical records of 219 patients were studied. In 7 of 43 patients (16%) who had undergone laparoscopy and 3 of 30 patients (10%) who had undergon...
Industry life-cycle research on firm survival concentrates on the effects of entry timing, pre-entry experience, and innovativeness. However, findings on how these effects change over different stages of the life cycle are scarce. To fill this gap, we perform a fuzzy-set qualitative comparative analysis on a dataset of 58 video game device producers in six product generations. We find that both...
To investigate the effect of drought stress and plant density on yield and yield components of maize KSc 301 hybrid, a two-year study (2007-2008) was carried out in Varamin Agricultural Research Center by using strip split plot randomized based on complete block design in three replications. Four water stress levels (before flowering, during flowering and grain filling stage and no stress) were...
In this paper, a novel hybrid optimization algorithm, which combines a firefly algorithms and Artificial Bee Colony algorithm (FFAABC), is proposed for solving the economic power dispatch (EPD) problem. The hybrid algorithm is structured with two stages. The first stage uses the search by firefly algorithm (FFA) and second stage is a search with Artificial Bee Colony algorithm (ABC). The hybrid...
This study was set up in the research station of Rice Research Institute of Iran (RRII) to determine the response of three hetrotic Indica × Indica rice hybrids (Bahar1, IR75221H and IR69688H) to anther culture on four induction media (N6, modified N6, chu and modified chu). To evaluate hybrids, the percentage of calluses which had been made from anthers in early uni- to mid- uninucleate stage ...

objectives: the main purpose of this experimental research was to create an animal model of ptsd based on the main features of the disorder: trauma exposure, situational reminders (sr), behavioral anxiety and remedy in response to anxiolytic medications. method: 6 inbred female sprague-dawley rats were obtained and evaluated in the elevated plus-maze test in 3 stages: 1- baseline 2- underwater ...
Problem solving is one of the most important skills for students. Meanwhile, logical thinking ability to solve problems by relying on mental abilities. The purpose this research describe problem process students with different levels thinking. This an exploratory qualitative involving eighth grade SMP N 5 Tuban who have as subjects. subjects were interviewed 4 Instruments measure level used Gro...
A hybrid protein of ricin and the enzymatically active fragment A of diphtheria toxin (toxin A) has been synthesized and purified. The diphtheria toxin A fragment of the hybrid protein is shown to enter the cytosol compartment of HeLa cells, its presence assayed by the fall of intracellular elongation factor II (EF-2) and the rise of ADP-ribosylated EF-2. Hybrid entrance to HeLa cells is blocke...
