To do so, the majority of work described herein refers to work performed using arm cycling (arm pedaling or arm cranking) as a model of a rhythmic motor output used to examine the neural control of human locomotion.The current study evaluated the hypothesis that 6 mo of exercise-based cardiac rehabilitation (CR) would improve sympathetic neural recruitment in patients with ischemic heart disease (IHD). Microneurography was used to evaluate action potential (AP) discharge patterns within bursts of muscle sympathetic nerve activity (MSNA), in 11 patients with IHD (1 female; 61 ± 9 yr) pre (pre-CR) and post (post-CR) 6 mo of aerobic and resistance training-based CR. Measures were made at baseline and during maximal voluntary end-inspiratory (EI-APN) and end-expiratory apneas (EE-APN). Data were analyzed during 1 min of baseline and the second half of apneas. At baseline, overall sympathetic activity was less post-CR (all P 0.05), but increases in both within-burst AP firing frequency (Δpre-CR 2 ± 3 AP spikes/burst vs. Δpost-CR 4 ± 3 AP spikes/burst; P = 0.02) and AP cluster recruitment (Δpre-CR -1 ± 2 vs. Δpost-CR 2 ± 2; P less then 0.01) were observed in post-CR tests. In contrast, during EE-APN, AP firing frequency was not different post-CR compared with pre-CR tests (Δpre-CR 269 ± 202 spikes/min vs. Δpost-CR 232 ± 225 spikes/min; P = 0.54), and CR did not modify the recruitment of new AP clusters (Δpre-CR -1 ± 3 vs. Δpost-CR 0 ± 1; P = 0.39), or within-burst firing frequency (Δpre-CR 3 ± 3 AP spikes/burst vs. Δpost-CR 2 ± 2 AP spikes/burst; P = 0.21). These data indicate that CR improves some of the sympathetic nervous system dysregulation associated with cardiovascular disease, primarily via a reduction in resting sympathetic activation. However, the benefits of CR on sympathetic neural recruitment may depend upon the magnitude of initial impairment. To explore whether prostate-specific antigen (PSA) affects the choice of prostate puncture methods by comparing MRI-ultrasound fusion targeted biopsy (MRI-TBx) with transrectal ultrasound systematic biopsy (TRUS-SBx) in the detection of prostate cancer (PCa), clinically significant prostate cancer (csPCa) and non-clinically significant prostate cancer (nsPCa) in different PSA groups (<10.0,10.0-20.0 and>20.0 ng ml ). A total of 190 patients with 215 lesions who underwent both MRI-TBx and TRUS-SBx were included in this retrospective study. PSA was measured pre-operatively and stratified to three levels. The detection rates of PCa, csPCa and nsPCa through different methods (MRI-TBx, TRUS-SBx, or MRI-TBx +TRUS SBx) were compared with stratification by PSA. Among the 190 patients, the histopathological results revealed PCa in 126 cases, including 119 csPCa. In PSA <10.0 ng ml group, although the detection rates of PCa and csPCa by MRI-TBx were higher than those of TRUS-SBx, no significant differences were observed ( = 0.741; = 0.400). In PSA 10.0-20.0 ng ml group, difference between the detection rate of csPCa with TRUS-SBx and the combined method was statistically significant ( = 0.044). As for PSA >20.0 ng ml , MRI-TBx had a higher csPCa rate than TRUS-SBx with no statistical significance noted ( = 0.600). MRI-TBx combined with TRUS-SBx could be suitable as a standard detection approach for csPCa in patients with PSA 10.0-20.0 ng ml . As for PSA >20.0 and <10.0 ng ml , both MRI-TBx and TRUS-SBx might provide effective solutions for tumor detection. This study gives an account of choosing appropriate prostate puncture methods through PSA level. This study gives an account of choosing appropriate prostate puncture methods through PSA level. This study aimed to determine the discrimination power of apparent diffusion coefficient (ADC) for cystic lesions in the jaw using MRI. We selected 127 cystic lesions, comprising dentigerous
