Problem: 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..

Solution: yes
Explanation: Title is appropriate for the given abstract because the focus of this abstract is cerebral white matter assesment.

Problem: Abstract: Metastatic tumor cells that actively migrate and invade surrounding tissues rely on invadopodia to degrade extracellular matrix (ECM) barriers. Invadopodia are membrane protrusions that localize enzymes required for ECM degradation. Little is known about the formation, function, and regulation of invadopodia. Here, we show that invadopodia have two distinct aspects: (a) structural for organizing the cellular actin cytoskeleton to form membrane protrusions and (b) functional for using proteolytic enzyme(s) for ECM degradation. Small interfering RNA (siRNA) inhibition established that organization of invadopodia structure requires cortactin, whereas protease inhibitor studies identified membrane type 1 matrix metalloproteinase (MT1-MMP) as the key invadopodial enzyme responsible for gelatin matrix degradation in the breast carcinoma cell line MDA-MB-231. The inhibition of invadopodial structure assembly by cortactin depletion resulted in a block of matrix degradation due to failure of invadopodia formation. Either protease inhibition or MT1-MMP siRNA depletion moderately decreased the formation of invadopodial structures that were identified as actin-cortactin accumulations at the ventral cell membrane adherent to matrix. The invadopodia that were able to form upon MT1-MMP inhibition or depletion retained actin-cortactin accumulations but were unable to degrade matrix. Examination of cells at different time points as well as live-cell imaging revealed four distinct invadopodial stages: membrane cortactin aggregation at membranes adherent to matrix, MT1-MMP accumulation at the region of cortactin accumulation, matrix degradation at the invadopodia region, and subsequent cortactin dissociation from the area of continued MT1-MMP accumulation associated with foci of degraded matrix. Based on these results, we propose a stepwise model of invadopodia formation and function..
