ABSTRACT: Total hip replacement is considered to be a highly successful and routine surgery; however, the internal components produce particles through friction and wear in the device.These particles are identified as one of the main reasons for total hip revisions.The generated, biologically active, particles provoke the formation of osteolytic ar

The interactions of legumes with symbiotic nitrogen-fixing bacteria cause the formation of specialized lateral root organs called root nodules.It has been postulated that this root nodule symbiosis system has recruited factors that act in early signaling pathways (common SYM genes) partly from the ancestral mycorrhizal symbiosis.However, the origin
Tethering a fly for stationary flight allows for exquisite control of its sensory input, such as visual or olfactory stimuli or a punishing infrared laser beam.A torque meter measures the turning attempts of the tethered fly around its vertical body axis.By punishing, say, left turning attempts (in a homogeneous environment), one can train a fly to
