Computational modeling of blast-induced traumatic brain injury
Blast-induced TBI has gained prominence in recent years due to the conflicts in Iraq and Afghanistan, yet little is known about the mechanical effects of blasts on the human head; no injury thresholds have been established for blast effects on the head, and even direct transmission of the shock …

Facial protective devices for blast-induced traumatic brain injury mitigation
… response of a human head subjected to a blast. Finite element models of the helmet with and without faceshields and goggles were developed from geometries of the Advanced Combat Helmet and the Enhanced Combat Helmet provided by the Natick Soldier Research, Development and Engineering …

Mechanics of blast-induced traumatic brain injury in porcine brain tissue
<p>Blast-induced traumatic brain injury (bTBI) often results from the detonation of improvised explosive devices (IEDs) in war settings. However, the material properties of the brain and their changes during and after bTBI are currently not well understood. Characterizing brain tissue is …

Mitochondrial Dynamics Alteration in Astrocytes Following Primary Blast-Induced Traumatic Brain Injury
Mild blast-induced traumatic brain injury (bTBI) is a modality of injury that has been of major concern considering a large number of military personnel exposed to the blast wave from explosives. bTBI results from the propagation of high-pressure static blast forces and their subsequent energy …

Fluid-filled helmet liner concept for protection against blast-induced traumatic brain injury
… survivability in combat has increased, but blast-induced Traumatic Brain Injury (TBI) has become a prevalent injury in the battlefield. Often referred to as the "signature wound" of the current U.S. conflicts, blast-induced TBI is not a very well understood injury. In an effort to gain more …

Design of a composite combat helmet liner for prevention of blast-induced traumatic brain injury
Air blast-induced traumatic brain injuries (TBIs) represent a significant percentage of military personnel injuries observed in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Prevalence of blast-induced TBIs is attributed to several factors, including improved body armor, …

Pressure versus impulse graph for blast-induced traumatic brain injury and correlation to observable blast injuries
… increased use of explosive devices in combat, blast induced traumatic brain injury (bTBI) has become one of the signature wounds in current conflicts. Animal studies have been conducted to understand the mechanisms in the brain and a pressure versus time graph has been produced. However, the …

The Influence of Biomechanics on Acute Spatial and Temporal Pathophysiology Following Blast-Induced Traumatic Brain Injury
Blast-induced traumatic brain injury (bTBI) remains a significant problem among military populations. When an explosion occurs, a high magnitude positive pressure rapidly propagates away from the detonation source. Upon contact, biological tissues throughout the body undergo deformation at high …

Understanding new regimes for light-matter interactions
… bone piezoelectricity may be a source of intense blast-induced electric fields in the brain, with magnitudes and timescales comparable to fields with known neurological effects, and may play a role in blast-induced traumatic brain injury. We will also shed new light on the localization of photons …

Experimental study of bubble rupture during shock-fluid interaction
… detonation. There are four distinct types of blast induced neurotrauma (BINT): 1) these caused by supersonic shock waves propagating in the atmosphere (primary), 2) high velocity impact of shrapnel and debris (secondary) 3) acceleration and deceleration of the body and collision with the solid …

High-Definition Fiber Tracking Study of the Executive Control Network in Blast-Related Traumatic Brain Injury
Blast-induced traumatic brain injury (bTBI) is common in Iraq and Afghanistan war veterans. However, subtle neural alterations and lack of a definitive biomarker impede clinical detection. The current study evaluated structure and functional correlates of executive control network (ECN) white …

Shock wave interaction with a fluid filled cylinder experimental methods
… and Afghanistan, many soldiers sustained bTBI (blast-induced traumatic brain injury). The blasts are created by extensive use of improvised explosive devices (IED's). Whether pure blast-shock waves cause TBI or what is the mechanism of injury are not fully known. Research efforts are underway to …

Development of MRI-based Yucatan Minipig Brain Template
… neuroscience where recent studies, investigating blast-induced traumatic brain injury, stroke, and glioblastoma, aim to uncover brain injury mechanisms [1-3]. Magnetic Resonance Imaging (MRI) has the potential to validate and optimize unknown parameters in controlled populations. The key to …

Shockwave energy dissipation by mechanoresponsive materials
… with extremely short duration about nanoseconds. Blast-induced traumatic brain injury sustained by personnel exposed to shockwave-generating high-energy explosives results in costly and debilitating health effects. Novel approaches for shockwave energy dissipation (SWED) are demanded since …
