Indeed, as shown in Figure 4 A, we observed an age-related decrease in the caffeine releasable SR calcium content [from 10.1 ± 0.8 amol/pF in the younger patients to 6.5 ± 0.4 amol/pF in the middle aged patients (P < 0.01) and 6.4 ± 0.6 amol/pF in the older group (P < 0.05)].
This may be related to an age-related decrease in the size and/or number of fast-twitch Type II muscle fibers in the dorsiflexor tibialis anterior and the plantarflexor gastrocnemius [59].
All four PFAA treatments produced a concentration-related decrease in the calculated average area occupied by lipid per cell.
Moreover, the high reduction of neutral detergent fiber digestibility (15.3% ± 3.65) in fermenters with high F/B suggested a pH-related decrease in the cellulolytic bacterial community as the F/B increased.
This decrease may be a result of both an increased recruitment to the sites of infection as well as a drug-related decrease in the proliferative capacity of CMV specific CD4 T cells.
Adding PTHrP (1-36) at concentrations of 0.1 nM to 100 nM caused a dose-related decrease in the number of bone nodules.
PTHrP (1-36) causedose-relatedatedecreasese in the number of bone nodules in low plating density cultures, but did not affect the number of AP-positive cell colonies.
A statistically significant reduction in the primordial/primary follicle pool was observed in the BDE01 group (p < 0.05), and a dose-related decrease in the number of secondary follicles was seen in females exposed to PBDE-99 that was significant in the BDE10 group (p < 0.05).
The number of open arm entries in the EPM) also demonstrated a stress-related decrease in the number of entries to the open arm in group ST (1.3 ± 0.4 times; P = 0.02) but not in group SC (2.7 ± 1.3 times), compared with group CT (6.6 ± 1.6 times; F 2,16) = 5.10, P = 0.022) immediately after stress.
Neuromuscular fatigue is an exercise-related decrease in the maximal voluntary force or power of a muscle or muscle group, whether or not the task can be sustained.
