or saline vehicle. Injured parietal cortex and underlying hippocampus

were probed via western blotting on post-injury day (PID) 2, 4, and 14.

We examined various markers of NMDAR mediated plasticity, including

NR2A, NR2B, NR1, CaMKII, pCaMKII, CREB, and pCREB. This study

is novel in charting the time-course of plasticity-related molecular

changes after injury and with glutamatergic treatment. We found that

reductions in NR2A (16% reduction in untreated injured vs. uninjured,

p

<

0.1) and pCaMKII (39% reduction in untreated injured vs. uninjured,

p

<

0.05) in the injured rat hippocampus on PID4 were alleviated fol-

lowing treatment with DCS. Further, NR2A expression in injured PID4

hippocampus was significantly higher in treated injured animals than in

untreated injured animals at the p

<

0.1 level. Injured rats treated with

DCS have similar levels of NMDAR relatedmolecular markers compared

to uninjured, untreated controls (there were no significant differences

between treated injured animals and controls in NMDAR related mo-

lecular expression). Early DCS treatment helps to alleviate some early

deficits in NMDAR related signaling in injured hippocampus following

severe lateral fluid percussive injury. Thus, DCS administration following

pediatric TBI in the subacute phase represents a powerful potential target

for early intervention. This research was supported by UCLA BIRC,

The lack of reproducibility in many areas of science, including spinal

cord injury (SCI) research, results in increased operational costs and a

decline in the productivity of research and development. Poor repro-

ducibility is due in part to the lack of common reporting standards. To

address this significant problem, over the past four years an

ad hoc

consortium of scientists has developed a minimal information reporting

standard for SCI experiments, known as MIASCI. Our latest version of

MIASCI captures information about 11 aspects of an SCI experiment:

investigator, organism, surgery, perturbagen, cell transplantation, bio-

materials, histology, immunohistochemistry, imaging, behavior, bio-

chemistry, molecular biology, and data analysis and statistics. For each

of these aspects, MIASCI enables scientists to capture essential meta-

data about the study design, materials and methods. Collecting all the

information needed to comply with MIASCI is challenging and if an

entirely manual entry approach is used, it is difficult to describe ex-

perimental workflows or study groups, and the relationships between

them. Here, we present

MIASCI Online

, a web-based annotation tool

that makes use of existing ontologies and addresses these problems.

Importantly, MIASCI Online produces output that is both human

readable and ready for deposit and analysis in data- and knowledge-

bases. Example queries supported by MIASCI Online will be illustrated

and their role in facilitating scientific discovery discussed.

Increasing prevalence of traumatic brain injury (TBI) and comorbid

anxiety disorders such as post-traumatic stress disorder (PTSD)

warrants attention for better understanding of underlying patho-

mechanisms. The amygdala is involved in processing emotional and

stressful stimuli and is implicated in anxiety disorders, like PTSD.

The basolateral amygdala (BLA) receives rich inputs from sensory

and limbic structures and modulates stress, fear, and emotional

learning and memory. Structural plasticity within amygdala circuits

may underlie emotional sequelae of TBI. The purpose of this study

was to quantify temporal changes in dendritic complexity of excit-

atory neurons in the BLA after TBI. Adult male rats were subjected

to a diffuse brain injury by midline fluid percussion or a sham injury.

At post-injury days (PID) 1, 7 and 28, brain tissue from sham and

brain-injured rats was processed for Golgi or silver stain, and ana-

lyzed to quantify BLA dendritic complexity in pyramidal and stellate

neurons and regional neuropathology, respectively. Compared to

sham, brain-injured rats at all PID investigated showed enhanced

dendritic complexity proximal to the soma, and at later time points at

distal portions in both BLA cell types as revealed by Sholl analysis.

However, the BLA was spared from neuropathology demonstrated

by limited argyrophilic accumulation at all time points measured, in

contrast to other regions. These data suggest an immediate and

chronic enhancement of dendritic complexity within the BLA after a

single TBI, without neuropathology. Increased dendritic complexity

would alter information processing into and through the amygdala,

which may contribute to affective symptoms after TBI, and possibly

the development of PTSD.
