background: establishment of viable pregnancy requires embryo implantation and placentation. ectopic pregnancy (ep) is a pregnancy complication which occurs when an embryo implants outside of the uterine cavity, most often in a fallopian tube. on the other hand, an important aspect of successful implantation is angiogenesis. vascular endothelial growth factor (vegf) is a potent angiogenic facto...

Immobilization of cells inside microfluidic devices is a promising approach for enabling studies related to drug screening and cell biology. Despite extensive studies in using grooved substrates for immobilizing cells inside channels, a systematic study of the effects of various parameters that influence cell docking and retention within grooved substrates has not been performed. We demonstrate...

PURPOSE The low masticatory efficiency of denture prostheses impairs the ability of wearers to consume high-fiber foods. Hence, artificial teeth with high masticatory efficiency are required. This study aimed to establish an occlusal surface design for posterior artificial teeth in denture prostheses that is compatible with the existing artificial teeth arrangement and that has high masticatory...

The current paper studies the pressure generated between two parallel grooved surfaces, as occurs in oil control ring internal combustion engines. It is shown that depends significantly on position of groove intersections, and thus a single calculation cannot describe during full passage over pattern. Furthermore, it introduction distance variation reduces variation, but does not affect mean ge...
