In another word, the actual faradaic efficiency was observed experimentally with IDA electrodes, which is often misled as 100% in many works. The diffusion of the reaction products has been 'seen' as well with the generator-collector mode. This general tool (IDA) may make more contributions on the study of reaction process of all electrocatalytical reactions.Although the contact electrification(CE) (or usually called "triboelectrification(TE)") effect has been known for over 2600 years, its scientific mechanism still remains debated after decades. Interest in studying CE has been recently revisited due to the invention of the triboelectric nanogenerators(TENGs), which are the most effective approach for converting random, low-frequency mechanical energy into electric power for distributed energy applications. This review is composed of three parts that are coherently linked ranging from basic physics, through classical electrodynamics, and to technological advances and engineering applications. First, the mechanisms of CE are studied for general cases involving solids, liquids and gas phases. Various physics models are presented to explain the fundamentals of CE by illustrating that electron transfer is the dominant mechanism for CE for solid-solid interfaces. Electron transfer also occurs in the CE at liquid-solid and liquid-liquid interfaces. An electron-cloud theory for quantifying the performance and electromagnetic behaviour of TENGs in general.Objective. Cognitive and memory impairments are common sequelae after stroke, yet how middle cerebral artery (MCA) stroke chronically affects the neural activity of the hippocampus, a brain region critical for memory but remote from the stroke epicenter, is poorly understood. Environmental enrichment (EE) improves cognition following stroke; however, the electrophysiology that underlies this behavioral intervention is still elusive.Approach.We recorded extracellular local field potentials simultaneously from sensorimotor cortex and hippocampus in rats during urethane anesthesia following MCA occlusion and subsequent EE treatment.Main results.We found that MCA stroke significantly impacted the electrophysiology in the hippocampus, in particular it disrupted characteristics of sharp-wave associated ripples (SPW-Rs) altered brain state, and disrupted phase amplitude coupling (PAC) within the hippocampus and between the cortex and hippocampus. Importantly, we show that EE mitigates stroke-induced changes to SPW-R characteristics but does not restore hippocampal brain state or PAC.Significance.These results begin to uncover the complex interaction between cognitive deficit following stroke and EE treatment, providing a testbed to assess different strategies for therapeutics following stroke.
The purpose of this study was to investigate the accuracy of the published prediction equations for determining level overground walking energy cost in young adults.

In total, 148 healthy young adults volunteered to participate in this study. Resting metabolic rate and energy expenditure variables at speeds of 4, 5, and 6km/h were measured by indirect calorimetry, walking energy expenditure was estimated by 3 published equations.

The gross and net metabolic rate per mile of level overground walking increased with increased speed (all P < .01). Females were less economical than males. The present findings revealed that the American College of Sports Medicine and Pandolf etal equations significantly underestimated the energy cost of overground walking at all speeds (all P < .01) in young adults. The percentage mean bias for American College of Sports Medicine, Pandolf etal, and Weyand etal was 12.4%, 16.8%, 1.4% (4km/h); 21.6%, 15.8%, 7.1% (5km/h); and 27.6%, 12%, 6.6% (6km/h). Bland-Altman plots and prediction error analysis showed that the Weyand etal was the most accurate in 3 existing equations.

The Weyand etal equation appears to be the most suitable for the prediction of overground walking energy expenditure in young adults.

To assess the feasibility and clinical benefits of supervised, intradialytic exercise in older patients.

Multicenter one-arm feasibility study. The main outcome was feasibility (ease of recruitment, dropout rate, adherence, affective valence, and adverse events). The secondary outcomes were physical capacity (five-repetition sit-to-stand, 60-s sit-to-stand tests, and grip strength), quality of life (36-Item Short-Form Health Survey), quality of sleep (Pittsburgh Sleep Quality Index), depressive symptoms (Beck Depression Inventory), and dialysis efficacy (Kt/V and urea reduction ratio).

About 79% of the screened patients agreed to participate (n = 25, 73 [66-77]years). The dropout rate was high (32%), but adherence remained high among the participants who completed the study (94%). Improvements were found in the five-repetition sit-to-stand (p < .001), 60-ssit-to-stand tests (p = .028), 36-Item Short-Form Health Survey mental component score (p = .008), depressive symptoms (p = .006), and quality of sleep (p = .035).

The investigation of the dynamic joint stiffness behavior may help to understand the lower limb joints' contribution to these changes. This study aimed to investigate the dynamic stiffness of lower limb joints in response to the increased load carried while walking. Thirteen participants walked in two conditions unloaded (an empty backpack) and loaded (the same backpack plus added mass corresponding to 30% of body mass). Dynamic stiffness was calculated as the linear slope of the regression line on the moment-angle curve during the power absorption phases of the ankle, knee, and hip in the sagittal plane. The results showed that ankle (P = .002) and knee (P less then .001) increased their dynamic stiffness during loaded walking compared with unloaded, but no difference was observed at the hip (P = .332). The dynamic stiffness changes were different among joints (P less then .001) ankle and knee changes were not different (P less then .992), but they had a greater change than hip (P less then .001). The nonuniform increases in lower limb joint dynamic stiffness suggest that the ankle and knee are critical joints to deal with the extra loading.
Performance in strength and assessment of patellar tracking is important for patients with arthrofibrosis after anterior cruciate ligament (ACL) reconstruction.

The study was to examine the difference of patellofemoral kinematics between the affected and the contralateral limb and to evaluate the relationship between knee extensor strength and patellofemoral kinematics in patients with arthrofibrosis after ACL reconstruction.

Cohort study (diagnosis); level of evidence, 3.

Laboratory.

A prospective cohort of 20 patients with arthrofibrosis after ACL reconstruction was recruited.

A total of 20 patients who underwent arthroscopic reconstruction of the double-bundle ACL with a hamstring tendon autograft received standardized patellofemoral kinematics testing and knee extensor strength testing within 6months after primary ACL reconstruction. Computed tomography and dual fluoroscopic imaging were used to evaluate in vivo patellofemoral kinematics of affected and contralateral knees during a lunge task.tic knee demonstrates the importance of knee extensor strength in the diagnosis and treatment of patients with knee arthrofibrosis. The knee extensor mechanism strength has high sensitivity but low specificity in identifying a decrease in patellar inferior shift in patients with arthrofibrosis after ACL reconstruction.
Patients with arthrofibrosis after ACL reconstruction presented decreased patellar mobility in the arthrofibrotic knee compared with the contralateral knee. buy Uprosertib The strong correlation between knee extensor strength and patellar inferior shift of the arthrofibrotic knee demonstrates the importance of knee extensor strength in the diagnosis and treatment of patients with knee arthrofibrosis.

The incidence of squamous cell carcinoma of the anus (SCCA) is increasing, particularly among the elderly (age ≥65 years). We sought to compare patterns of care for the treatment of SCCA in elderly versus nonelderly patients.

Data for patients with stages I-III SCCA diagnosed from 2004 through 2015 were obtained from the National Cancer Database. Patients were categorized as having received standard-of-care (SOC) chemoradiation (CRT) with multiagent chemotherapy, non-SOC therapy, palliative therapy, or no treatment. Differences in treatment groups were tested using the chi-square test. We used logistic regression to identify predictors of SOC CRT and multiagent versus single-agent chemotherapy in patients receiving CRT. Propensity score matching was used to compare overall survival (OS) in elderly patients receiving multiagent versus single-agent chemotherapy for those receiving CRT.

We identified 9,156 elderly and 17,640 nonelderly patients. A lower proportion of elderly versus nonelderly patients (54.the optimal treatment approach for this vulnerable population remains undefined.
In this comprehensive study of patients with stages I-III SCCA, elderly patients were less likely than nonelderly patients to receive SOC CRT. The low proportion of elderly patients receiving SOC CRT with multiagent chemotherapy for localized anal cancer suggests that the optimal treatment approach for this vulnerable population remains undefined.
Neonatal nurses require knowledge of evidence-based interventions that can be utilized for supporting oral feeding skills in preterm infants. Little is known about the impact of education/training programs on neonatal nurses' knowledge of this topic.

This study was conducted to determine the effect of a training program about evidence-based interventions for the transition to and support of oral feeding in preterm infants on the knowledge levels of neonatal nurses.

We conducted a pretest-posttest studywith 73 neonatal nurses in a research and training hospital. Participants completed a demographic information form and their knowledge about oral feeding in preterm infants was assessed before and after a 240-min training about the transition to oral feeding and evidence-based therapeutic interventions to promote preterm infants' oral feeding skills.

Posttest scores evaluated at 1 week (81.6 ± 6.8) and 1 month (79.5 ± 6.5) after the training were significantly higher than pre-test scores (66.8 ± 6.9) (p < 0.001).

Neonatal nurses showed higher levels of knowledge about evidence-based interventions for supporting oral feeding skills in preterm infants at 1 week and 1 month after the training program compared to their knowledge before training.

Providing training to neonatal intensive care nurses on the transition to oral feeding in preterm infants will increase their level of knowledge and ensure that oral feeding interventions for preterm infants can be implemented using evidence-based therapeutic methods.
