Background: Transcranial Ultrasound Stimulation (tUS) is an emerging technique that uses ultrasonic waves to noninvasively modulate brain activity. As with other forms of non-invasive brain stimulation (NIBS), tUS may be useful for altering cortical excitability and neuroplasticity for a variety of research and clinical applications. The effects of tUS on cortical excitability are still unclear, and further complications arise from the wide parameter space offered by various types of devices, transducer arrangements, and stimulation protocols. Diagnostic ultrasound imaging devices are safe, commonly available systems that may be useful for tUS. However, the feasibility of modifying brain activity with diagnostic tUS …

Bone is an engineering marvel that achieves a unique combination of stiffness and toughness exceeding that of synthesized materials. In orthopedics, we are currently challenged for the child population that needs a less stiff but a tougher bone substitute than adults. Recent evidence suggests that the relationship between inter-molecular connections that involve the two main bone building blocks, TropoCollagen molecules (TC) and carbonated Hydroxyapatite (cAp), and bone macroscopic mechanical properties, stiffness and toughness, are key to building bone substitute materials for children. The goal of our study is to establish how inter-molecular connections that occur during bone mineralization are related …

Atherosclerotic plaque localizes in predictable areas such as arches and bifurcations which are characterized by disturbed flow patterns and the resulting damage and dysfunction to the endothelium. Endothelial cells (ECs) under sustained laminar flow align in the direction of flow; however, under disturbed flow conditions, ECs sustain damage to their glycocalyx (GCX) which results in unaligned and rounder cells. An investigation into the role of NDST1 sulfation of heparan sulfate (HS), a key component of many proteoglycans which make up the GCX, was conducted. The descending aortas (DAs) of transgenic mice with conditional knockouts (KOs) of NDST1 in vascular ECs …
