44%) over a ten-metre sprint. Additionally, angular variables of the ankles during sprint initiation were found to be significantly different between false and forward step conditions. Findings suggest that the false step may be beneficial for athletes and is an advantageous technique for achieving a rapid change in velocity.Rationale Angiogenesis promotes neurological recovery after stroke and is associated with longer survival of stroke patients. Cerebral angiogenesis is tightly controlled by certain microRNAs (miRs), such as the miR-15a/16-1 cluster, among others. However, the function of the miR-15a/16-1 cluster in endothelium on post-ischemic cerebral angiogenesis is not known. Objective To investigate the functional significance and molecular mechanism of endothelial miR-15a/16-1 cluster on angiogenesis in the ischemic brain. Methods and Results Endothelial cell -selective miR-15a/16-1 conditional knockout (EC-miR-15a/16-1 cKO) mice and WT littermate controls were subjected to 1h middle cerebral artery occlusion (MCAO) followed by 28d reperfusion. Deletion of miR-15a/16-1 cluster in endothelium attenuates post-stroke brain infarction and atrophy, and improves the long-term sensorimotor and cognitive recovery against ischemic stroke. Endothelium-targeted deletion of the miR-15a/16-1 cluster also enhances post-stroke angiogenwithin three prime untranslated regions (3'-UTRs) of those mRNAs. Conclusions Endothelial miR-15a/16-1 cluster is a negative regulator for post-ischemic cerebral angiogenesis and long-term neurological recovery. Inhibition of miR-15a/16-1 function in cerebrovascular endothelium may be a legitimate therapeutic approach for stroke recovery.Purpose To validate and compare a novel model based on the critical power (CP) concept that describes the entire domain of maximal mean power (MMP) data from cyclists.Methods An omni-domain power-duration (OmPD) model was derived whereby the rate of W' expenditure is bound by maximum sprint power and the power at prolonged durations declines from CP log-linearly. The three-parameter CP (3CP) and exponential (Exp) models were likewise extended with the log-linear decay function (Om3CP and OmExp). Each model bounds W' using a different nonconstant function, W'eff (effective W'). Models were fit to MMP data from nine cyclists who also completed four time-trials (TTs).Results The OmPD and Om3CP residuals (4 ± 1%) were smaller than the OmExp residuals (6 ± 2%; P less then 0.001). W'eff predicted by the OmPD model was stable between 120-1,800 s, whereas it varied for the Om3CP and OmExp models. TT prediction errors were not different between models (7 ± 5%, 8 ± 5%, 7 ± 6%; P = 0.914).Conclusion The OmPD offers similar or superior goodness-of-fit and better theoretical properties compared to the other models, such that it best extends the CP concept to short-sprint and prolonged-endurance performance.This study identified key somatic and demographic characteristics that benefit all swimmers and, at the same time, identified further characteristics that benefit only specific swimming strokes. Three hundred sixty-three competitive-level swimmers (male [n = 202]; female [n = 161]) participated in the study. We adopted a multiplicative, allometric regression model to identify the key characteristics associated with 100 m swimming speeds (controlling for age). The model was refined using backward elimination. Characteristics that benefited some but not all strokes were identified by introducing stroke-by-predictor variable interactions. The regression analysis revealed 7 "common" characteristics that benefited all swimmers suggesting that all swimmers benefit from having less body fat, broad shoulders and hips, a greater arm span (but shorter lower arms) and greater forearm girths with smaller relaxed arm girths. The 4 stroke-specific characteristics reveal that backstroke swimmers benefit from longer backs, a finding that can be likened to boats with longer hulls also travel faster through the water. Other stroke-by-predictor variable interactions (taken together) identified that butterfly swimmers are characterized by greater muscularity in the lower legs. These results highlight the importance of considering somatic and demographic characteristics of young swimmers for talent identification purposes (i.e., to ensure that swimmers realize their most appropriate strokes).Background The survival benefit associated with cumulative adherence to multiple clinical and lifestyle-related guideline recommendations for secondary prevention after acute myocardial infarction (AMI) is not well established. Selleckchem Linsitinib Methods and Results We examined adults with AMI (mean age 68 years; 64% men) surviving at least 30 (N=25 778) or 90 (N=24 200) days after discharge in a large integrated healthcare system in Northern California from 2008 to 2014. The association between all-cause death and adherence to 6 or 7 secondary prevention guideline recommendations including medical treatment (prescriptions for β-blockers, renin-angiotensin-aldosterone system inhibitors, lipid medications, and antiplatelet medications), risk factor control (blood pressure less then 140/90 mm Hg and low-density lipoprotein cholesterol less then 100 mg/dL), and lifestyle approaches (not smoking) at 30 or 90 days after AMI was evaluated with Cox proportional hazard models. To allow patients time to achieve low-density lipoprotein cholesterol less then 100 mg/dL, this metric was examined only among those alive 90 days after AMI. Overall guideline adherence was high (35% and 34% met 5 or 6 guidelines at 30 days; and 31% and 23% met 6 or 7 at 90 days, respectively). Greater guideline adherence was independently associated with lower mortality (hazard ratio, 0.57 [95% CI, 0.49-0.66] for those meeting 7 and hazard ratio, 0.69 [95% CI, 0.61-0.78] for those meeting 6 guidelines versus 0 to 3 guidelines in 90-day models, with similar results in the 30-day models), with significantly lower mortality per each additional guideline recommendation achieved. Conclusions In a large community-based population, cumulative adherence to guideline-recommended medical therapy, risk factor control, and lifestyle changes after AMI was associated with improved long-term survival. Full adherence was associated with the greatest survival benefit.
