Example input: Abstract: This study was designed to determine the influence of a long-term, moderate-intensity treadmill training program on the distribution of blood flow within and among muscles of rats during exercise. One group (T) of male Sprague-Dawley rats trained for 1 h/day for 13-17 wk at 30 m/min on a motor-driven treadmill. A second group (UT) of rats was conditioned for 10 min/day for 4 wk at the same speed. Muscle succinate dehydrogenase activities were higher in T than UT rats indicating a significant training effect. Blood flows (BFs) in 32 hindlimb muscles or muscle parts and other selected organs were measured in the two groups with radiolabeled microspheres during preexercise and while the rats ran for 30 s, 5 min, or 15 min at 30 m/min on the treadmill. The data indicate 1) there were no differences in total hindlimb muscle BF between UT and T rats at any time; however, 2) T rats had higher preexercise heart rates and higher muscle BFs in the deep red extensor muscles, suggesting a greater anticipatory response to the impending exercise; 3) T rats demonstrated more rapid elevations in BF in the red extensor muscles at the commencement of exercise; 4) T rats had higher BFs in red extensor muscles during exercise, whereas UT rats had higher BFs in white muscles; and 5) T rats maintained higher BFs in the visceral organs during exercise. These findings demonstrate that exercise training results in changes in the distribution of BF within and among muscles and among organs during exercise. Specifically, data indicate the high-oxidative motor units that are primarily recruited in the muscles during the initial stages of moderate treadmill exercise receive higher blood flows in the trained rats; this presumably contributes to increased resistance to fatigue..

Example output: yes
Example explanation: Title is appropriate for the given abstract because the focus of this abstract is cerebral white matter assesment.
Q: Abstract: BACKGROUND & AIMS Helicobacter pylori is an important etiologic factor in the development of gastric cancer. The aim of this study was to analyze the role of H. pylori infections in the induction of mutagenic events in gastric epithelial cells. The effect of a high-salt diet as a genotoxic risk factor was also investigated.
METHODS Big Blue transgenic male mice (C57Bl/6) were inoculated with H. pylori (strain SS1) or Helicobacter felis (strain CS1) for 6 and 12 months. The frequency and spectrum of mutations at the stomach level were assessed. Inflammatory host response and inducible nitric oxide synthase (iNOS) expression by reverse-transcription polymerase chain reaction and immunohistochemistry analysis were also performed.
RESULTS After 6 months, the gastric mutant frequency was 4-fold and 1.7-fold higher in mice infected with H. pylori and H. felis, respectively, than in uninfected mice. It was associated with a high frequency of transversions (AT --> CG and GC --> TA) known to result from oxidative damages. The Helicobacter-infected mice exhibited severe gastritis and a high level of iNOS messenger RNA expression. Hyperplasia developed 12 months after inoculation, and both the mutagenic effects and iNOS expression decreased in H. pylori- and H. felis-infected mice. No synergistic effects of a high-salt diet and Helicobacter infection were observed regarding the frequency of gastric mutation.
CONCLUSIONS A direct gastric mutagenic effect due to H. pylori infection in the Big Blue transgenic mouse model has been shown 6 months after inoculation. This genotoxicity can be attributable to oxidative DNA damage involving the inflammatory host response.. Title: Chronic Helicobacter pylori infections induce gastric mutations in mice.
