Bacillus subtilis is the best-characterized member of the Gram-positive bacteria. Its genome of 4,214,810 base pairs comprises 4,100 protein-coding genes. Of these protein-coding genes, 53% are represented once, while a quarter of the genome corresponds to several gene families that have been greatly expanded by gene duplication, the largest family(More)
Utilizing [18F]fluorodeoxyglucose positron emission tomography (FDG-PET), we studied the correlation between CMRglc and the level of consciousness within the first month following human traumatic brain injury. Forty-three FDG-PET scans obtained on 42 mild to severely head-injured patients were quantitatively analyzed for the determination of regional(More)
Changes in intracranial pressure (ICP) and mean arterial blood pressure (MABP) were measured for 30 min following an experimental fluid percussion traumatic brain injury in postnatal day 17 (P17), P28 and adult rats. Under enflurane anesthesia the left femoral artery was cannulated for MABP measurements and a 20 gauge needle was stereotaxically positioned(More)
STUDY DESIGN A retrospective study. OBJECTIVE To determine the safety of pedicle screw fixation in thoracic deformity correction. SUMMARY OF BACKGROUND DATA Pedicle screw fixation enables enhanced correction of spinal deformities. However, the technique is still not widely applied for thoracic deformities for fear of neurologic complications. (More)
To determine if a moderate traumatic brain injury (TBI) sustained early in life alters the capacity for developmental plasticity, 17-20-day-old rat pups received a lateral fluid percussion and then reared in an enriched environment for 17 days. Compared to sham-injured controls, this moderate TBI prevented the increase in cortical thickness (1.48 vs. 1.68(More)
There is growing evidence of the brain's ability to increase its reliance on alternative metabolic substrates under conditions of energy stress such as starvation, hypoxia and ischemia. We hypothesized that following traumatic brain injury (TBI), which results in immediate changes in energy metabolism, the adult brain increases uptake and oxidation of the(More)
Single-chain antigen-binding proteins are novel recombinant polypeptides, composed of an antibody variable light-chain amino acid sequence (VL) tethered to a variable heavy-chain sequence (VH) by a designed peptide that links the carboxyl terminus of the VL sequence to the amino terminus of the VH sequence. These proteins have the same specificities and(More)
The role of NAD(P)H:quinone reductase (QR; EC in the alcohol-derived protective effect against hepatotoxicity caused by acetaminophen (APAP) was studied. In mice pretreated with dicoumarol (30 mg/kg), an inhibitor of QR, hepatic necrosis caused by APAP (400 mg/kg) was potentiated. Hepatocellular injuries induced by APAP, as assessed by liver(More)
AIM Serum alpha-fetoprotein (AFP) is the most important tumor marker for hepatocellular carcinoma (HCC). Previous reports indicated that HCC was also associated with increased levels of interleukin (IL)-6, IL-10 and hepatocyte growth factor (HGF). This study investigated the role of these cytokines as tumor markers for HCC. METHOD A total of 128 adults(More)
Mitochondria are the major organelles that produce reactive oxygen species (ROS) and the main target of ROS-induced damage as observed in various pathological states including aging. Production of NADPH required for the regeneration of glutathione in the mitochondria is critical for scavenging mitochondrial ROS through glutathione reductase and peroxidase(More)
