Previously, we were able to demonstrate the neuroprotective effect of quercetin in an animal model of acute traumatic spinal cord injury. The objective of the present study was to determine whether any neuroprotective effect is seen when quercetin is administered in an animal model of traumatic brain injury. Twenty-six adult male Sprague-Dawley rats were(More)
We tested the hypothesis that quercetin, a potent Fe(2+)-chelating flavonoid, would decrease secondary damage following spinal cord trauma. MRI studies using the relaxation of the T1 proton signal caused by Fe(2+) ions and the dose-dependent reversal of this effect by addition of quercetin in aqueous solution were used to guide us to the dosage of quercetin(More)
BACKGROUND As has been shown previously, S-100beta levels in serum can be a useful predictor of brain damage after head trauma. This pilot study was designed to investigate whether urine samples, which are much easier to obtain, could be used for the same purpose instead of serum samples. METHODS Ninety-six consecutive patients admitted with head trauma(More)
The dominant hypothesis in multiple sclerosis is that it is an autoimmune disease; however, there is considerable evidence that the immune attack on myelin may be secondary to a cytodegenerative event. Furthermore, the immune modulating therapies longest in clinical use, although modulating the frequency and severity of exacerbation, do not affect long-term(More)
Dietary sulfur amino acid content is a major determinant of glutathione concentration in some tissues. We examined whether brain glutathione (GSH), a key component of antioxidant defense important for minimizing ischemic injury, was also responsive to short-term sulfur amino acid deficiency. Female Long-Evans adult rats were fed a sulfur-deficient L-amino(More)
In contrast to cardiovascular disease, the impact of nutritional status on the prevention and outcome of stroke has received limited investigation. We present a mechanism based on animal studies, clinical data, and epidemiological data by which protein-energy status in the acute stroke and immediate postinjury periods may affect outcome by regulating(More)
BACKGROUND It has been shown previously that S-100beta levels in serum correspond with the severity of central nervous system (CNS) trauma. It also has been suggested that S-100beta in CNS tissue is involved in neuroprotection and neuroregeneration. We have previously shown that administration of quercetin results in improved motor function in an animal(More)
We hypothesized that spinal manipulation (SM) would reduce strength imbalances between legs. Using an un-blinded randomized design, 28 males and 21 females (54 ± 19y) with at least a 15% difference in isometric strength between legs for hip flexion, extension, abduction, or knee flexion were randomized to treatment or placebo (mock spinal manipulation).(More)
