Abstract
Prior research has found that cognitive benefits of physical exercise and brain health in older adults may be enhanced when mental exercise is interactive simultaneously, as in exergaming. It is unclear whether the cognitive benefit can be maximized by increasing the degree of mental challenge during exercise. This randomized clinical trial (RCT), the Aerobic and Cognitive Exercise Study (ACES) sought to replicate and extend prior findings of added cognitive benefit from exergaming to those with or at risk for mild cognitive impairment (MCI). ACES compares the effects of 6 months of an exer-tour (virtual reality bike rides) with the effects of a more effortful exer-score (pedaling through a videogame to score points). Fourteen community-dwelling older adults meeting screening criteria for MCI (sMCI) were adherent to their assigned exercise for 6 months. The primary outcome was executive function, while secondary outcomes included memory and everyday cognitive function. Exer-tour and exer-score yielded significant moderate effects on executive function (Stroop A/C; d's = 0.51 and 0.47); there was no significant interaction effect. However, after 3 months the exer-tour revealed a significant and moderate effect, while exer-score showed little impact, as did a game-only condition. Both exer-tour and exer-score conditions also resulted in significant improvements in verbal memory. Effects appear to generalize to self-reported everyday cognitive function. Pilot data, including salivary biomarkers and structural MRI, were gathered at baseline and 6 months; exercise dose was associated with increased BDNF as well as increased gray matter volume in the PFC and ACC. Improvement in memory was associated with an increase in the DLPFC. Improved executive function was associated with increased expression of exosomal miRNA-9. Interactive physical and cognitive exercise (both high and low mental challenge) yielded similarly significant cognitive benefit for adherent sMCI exercisers over 6 months. A larger RCT is needed to confirm these findings. Further innovation and clinical trial data are needed to develop accessible, yet engaging and effective interventions to combat cognitive decline for the growing MCI population.

Abstract
OBJECTIVE To assess the 'real-world' performance of the newer generation of hydrogel coils in ruptured aneurysms. METHODS A multicenter retrospective study was carried out of angiographic and clinical outcome data on consecutive patients with ruptured aneurysms treated with at least 70% of the newer generation of hydrogel coils. Demographics and data on clinical grade, smoking, use of statins, aneurysm size, location, technique used, packing density, immediate angiographic result, angiographic follow-up, rebleeding and clinical outcome were obtained and analyzed. RESULTS Eighty patients (54F; 26M) with an average age of 55.1 years were entered in the study. Forty-four presented good clinical grade (Hunt and Hess 1 or 2). Forty-two (52.5%) aneurysms were ≤5 mm. 56.7% of the aneurysms were treated with simple coil embolization and 39.6% with balloon-assisted coil. The packing density ranged from 9.3% to 92.6% (mean 48.5%). Immediate occlusion rates (Raymond-Roy Scale) were: complete occlusion (class I) in 57.5%, residual neck (class II) in 32.5% and residual aneurysm (class III) in 10%. Intraoperative rupture occurred in 3 cases (3.75%). Clinical follow-up, available in 73 patients, showed a good outcome (modified Rankin Scale 0-2) in 76.3%. Preliminary data on imaging follow-up were available in 54 patients (average 6.8 months) with complete occlusion in 77.8%, residual neck in 20.3% and residual aneurysm in 1.9%. There was no re-hemorrhage. CONCLUSIONS Our data show that the use of the newer-generation hydrogel coils in the treatment of ruptured aneurysms is feasible, safe and effective with high immediate and mid-term occlusion rates and low morbidity.

Abstract
We solve the long-standing problem of making n perfect clones from m copies of one of two known pure states with minimum failure probability in the general case where the known states have arbitrary a priori probabilities. The solution emerges from a geometric formulation of the problem. This formulation reveals that cloning converges to state discrimination followed by state preparation as the number of clones goes to infinity. The convergence exhibits a phenomenon analogous to a second-order symmetry-breaking phase transition.

Abstract
Research demonstrates a positive effect of aerobic exercise on cognitive functioning in older adults. Unfortunately, aerobic exercise is often contraindicated for older adults due to cardiovascular and functional limitations. Low-intensity strengthening exercise may offer a practical alternative, but the neuropsychological benefits and potential neurophysiological mechanisms are less well understood. The current study evaluated the effects of a 10-week strengthening exercise intervention on cognitive functioning and EEG in a sample of 13 older adults with early dementia, and 9 normative controls. Results revealed beneficial effects of strengthening exercise on verbal memory coupled with frontal beta and delta power asymmetries and N200 amplitude asymmetry. Results point to increased cognitive efficiency following 10 weeks of strengthening exercise. The findings suggest it is feasible to conduct a strengthening intervention with early dementia patients, and to gather neuropsychological and neurophysiological data to evaluate outcomes. Strengthening exercise may serve as a useful alternative to aerobic exercise.
