Apoptosis, or programmed cell death, is a physiological form of cell death that is important for normal embryologic development and cell turnover in adult organisms. Cumulative evidence suggests that apoptosis can also be triggered in tissues without a high rate of cell turnover, including those within the central nervous system (CNS). In fact, a crucial(More)
Conventional and functional proteomics have significant potential to expand our understanding of traumatic brain injury (TBI) but have not yet been used. The purpose of the present study was to examine global hippocampal protein changes in postnatal day (PND) 17 immature rats 24 h after moderate controlled cortical impact (CCI). Silver nitrate stains or(More)
Poly(ADP-ribose) polymerase-1 (PARP-1) is a homeostatic enzyme that paradoxically contributes to disturbances in spatial memory acquisition after traumatic brain injury (TBI) in transgenic mice, thought to be related to depletion of its substrate nicotinamide adenine dinucleotide (NAD+). In this study, systemic administration of the PARP-1 inhibitor(More)
In this paper, we describe an internet-based signal processing laboratory that provides hands-on learning experiences in distributed learning environments. The laboratory is based on an object-oriented Java tool called Java Digital Signal Processing (J-DSP). J-DSP has been developed at Arizona State University (ASU) and is being used for a virtual(More)
Programmed cell death occurs after ischemic, excitotoxic, and traumatic brain injury (TBI). Recently, a caspase-independent pathway involving intranuclear translocation of mitochondrial apoptosis-inducing factor (AIF) has been reported in vitro; but whether this occurs after acute brain injury was unknown. To address this question adult rats were sacrificed(More)
Programmed cell death involves a complex and interrelated cascade of cysteine proteases termed caspases that are synthesized as inactive zymogens, which are proteolytically processed to active enzymes. Caspase-8 is an initiator caspase that becomes activated when Fas death receptor-Fas ligand (FasL) coupling on the cell surface leads to coalescence of a(More)
The stress response in injured brain is well characterized after experimental ischemic and traumatic brain injury (TBI); however, the induction and regulation of the stress response in humans after TBI remains largely undefined. Accordingly, we examined injured brain tissue from adult patients (n = 8) that underwent emergent surgical decompression after(More)
AIMS To evaluate the prevalence, associated risk factors and the impact on health related quality of life (HRQoL) of overactive bladder (OAB) among men and women aged ≥18 years in China, using the 2002 International Continence Society (ICS) definition. METHODS The population-based, cross-sectional field survey was conducted between June 2009 and February(More)
Increasing evidence suggests that apoptosis is a contributing factor to neuronal cell death in traumatic brain injury (TBI). There is increased expression, cleavage and activation of caspases as well as other proteins known to regulate apoptosis in neurons after TBI. These proteins include the proto-oncogene Bcl-2 which belongs to a family of proteins with(More)
OBJECTIVE The study aim was to assess the cumulative burden of polymorphisms located within four genetic loci previously associated with posttraumatic stress disorder (PTSD) among outpatients at risk for PTSD. METHODS Diagnostic interviews were completed and DNA samples collected among 412 pain patients to determine if FKBP5 (rs9470080), COMT (rs4680),(More)
