BACKGROUND/AIMS Cancer stem cells (CSCs) exhibit enhanced proliferative capacity and resistance to chemotherapy; however, choriocarcinoma CSCs have not yet been reported. In this study the human choriocarcinoma cell line JEG-3 was cultured in serum free media, and the characteristics of suspension and parental adherent JEG-3 cells were compared. METHODS Cell proliferation, colony-formation, s...

proteases play a key role in protein digestion in ticks and other haematophagous insects. our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. cells of the midgut endocytose blood components. blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. in this s...

Purpose – The purpose of this paper is to evaluate the locomotion performance of all-terrain rovers employing rocker-type suspension system. Design/methodology/approach – In this paper, a robot with advanced mobility features is presented and its locomotion performance is evaluated, following an analytical approach via extensive simulations. The vehicle features an independently controlled four...

Abstract The flow behavior of cementitious-like (limestone powder) suspension containing nano-Fe 3 O 4 particles at constant shear rate 10 s −1 , characterized by the evolution apparent viscosity over time, is investigated under various magnetic fields. Results show that limestone powder flow-state exhibits remarkable magneto-rheological responses, reflected a significant increase in after appl...

depression is a heterogenous, multifaceted disorder with symptoms manifested at the psychological, behavioral and physiological level. therefore, present study was designed as a model to analyze the long lasting effects of methylmercury chloride in male rats with a focus on depression like behavior. male albino rats of wistar strain were exposed orally to a dose of 2 mg/kg of methylmercury chlo...
