OBJECTIVE: With an aging population and the increasing prevalence of heart failure with preserved ejection fraction, developing strategies to prevent diastolic dysfunction is crucial. Regular endurance training has been suggested to be one such strategy. However, the underlying mechanisms of training, including the effect on left ventricular (LV) untwist, which promotes LV filling, are unclear and studies exploring the heart during exercise in the aging heart are lacking. METHODS: Cardiopulmonary exercise testing with speckle tracking echocardiography was realized in male subjects: 16 young athletes (YA), 19 young controls (YC), 22 middle-aged athletes (MA) with a lifelong history of endurance training, and 20 middle-aged controls (MC)...

BACKGROUND: Sexual dysfunction is common in midlife women and can have a significant negative impact on quality of life. Although treatments exist, there is little research on which sexual function outcomes and treatments midlife women prefer. AIM: To better understand the sexual function outcomes that were most important to sexually active women 45 to 60 years old and the types of treatments they would prefer from individual interviews and focus groups. METHODS: Twenty individual interviews and three focus groups (N = 39) were led by a trained facilitator, audio recorded, and transcribed...

Human behavior is supported by flexible neurophysiological processes that enable the fine-scale manipulation of information across distributed neural circuits. Yet, approaches for understanding the dynamics of these circuit interactions have been limited. One promising avenue for quantifying and describing these dynamics lies in multilayer network models. Here, networks are composed of nodes (which represent brain regions) and time-dependent edges (which represent statistical similarities in activity time series)...

BACKGROUND: Recently to improve depth perception, the performance of three-dimensional (3D) laparoscopic surgeries has increased. However, the effects of laparoscopic training using 3D are still unclear. This study aimed to clarify the effects of using a 3D monitor among novices in the early phase of training. METHODS: Participants were 40 novices who had never performed laparoscopic surgery (20 medical students and 20 junior residents). Three laparoscopic phantom tasks (task 1: touching markers on a flat disk with a rod; task 2: straight rod transfer through a single loop; and task 3: curved rod transfer through two loops) in the training box were performed ten times, respectively...

Surrogate-based simulation-optimization technique is an effective approach for optimizing the surfactant enhanced aquifer remediation (SEAR) strategy for clearing DNAPLs. The performance of the surrogate model, which is used to replace the simulation model for the aim of reducing computation burden, is the key of corresponding researches. However, previous researches are generally based on a stand-alone surrogate model, and rarely make efforts to improve the approximation accuracy of the surrogate model to the simulation model sufficiently by combining various methods...

BACKGROUND: Child abuse remains a national epidemic that has detrimental effects if unnoticed in the clinical setting. Extreme cases of child abuse, or non-accidental trauma (NAT), have large financial burdens associated with them due to treatment costs and long-term effects of abuse. Clinicians that have additional training and experience with pediatric trauma are better equipped to detect signs of NAT and have more experience reporting it. This additional training and experience can be measured by using the American College of Surgeons (ACS) Pediatric Trauma Verification...

OBJECTIVE: To estimate the risk for fetal trisomy 21 (T21) and other chromosomal abnormalities at 11-13 week's gestation using computational intelligence classification methods. METHODS: As a first step, we train the artificial neural networks with 72054 euploid pregnancies, 295 cases of T21 and 305 of other chromosomal abnormalities (OCA). Then, we sort the cases into two categories of "no-risk" and "risk". The cases of "no-risk" are no further examined, while the cases with "risk" are forwarded in Stage 2 for further examination where we classify them in three types of risk, namely "no-risk", "moderate-risk" and "high-risk"...

Sarcopenia and frailty are highly prevalent in older individuals, increasing the risk of disability and loss of independence. High intensity interval training (HIIT) may provide a robust intervention for both sarcopenia and frailty by achieving both strength and endurance benefits with lower time commitments than other exercise regimens. To better understand the impacts of HIIT during aging, we compared 24-month-old C57BL/6J sedentary mice with those that were administered 10-minute uphill treadmill HIIT sessions three times per week over 16 weeks...

Environmental enrichment techniques present animals with cognitive challenges while providing them opportunities to make choices and exert control over their environment. In this way, cognitive research and training is enriching to animals and can be used as a form of enrichment in zoos and aquariums. Cognitive research demonstrations also provide an opportunity to enhance visitor experience, as well as foster interactions between animals and keepers. We investigated how cognitive research sessions involving eastern box turtles (Terrapene carolina carolina) at Disney's Animal Kingdom(®) impacted both the rate of visitors coming to the exhibit and the amount of time they spent engaged...
