OBJECTIVE: To introduce a novel laparoscopic training system with a continuously perfused ex-vivo porcine liver for hepatobiliary surgery. BACKGROUND: Existing models for laparoscopic training, such as box trainers and virtual reality simulators, often fail to provide holistic training and real haptic feedback. We have formulated a new training system that addresses these problems. METHODS: Real-Liver Laptrainer consists of a porcine liver, customized mannequin, ex-vivo machine perfusion system, and monitoring software...

Gómez-Molina, J, Ogueta-Alday, A, Stickley, C, Tobalina, JC, Cabrejas-Ugartondo, J, and García-López, J. Differences in spatiotemporal parameters between trained runners and untrained participants. J Strength Cond Res 31(8): 2169-2175, 2017-The aim of this study was to compare the spatiotemporal parameters of trained runners and untrained participants with the same foot strike pattern (rearfoot) during running at controlled speeds. Twenty-one participants were classified in 2 groups according to their training experience: Trained (n = 10, amateur runners with long distance training experience) and Untrained (n = 11, healthy untrained participants)...

PURPOSE: New teacher evaluation systems have expanded the role of principals as instructional leaders, but little is known about principals' ability to promote teacher development through the evaluation process. We conducted a case study of principals' perspectives on evaluation and their experiences implementing observation and feedback cycles to better understand whether principals feel as though they are able to promote teacher development as evaluators. RESEARCH METHODS: We conducted interviews with a stratified random sample of 24 principals in an urban district that recently implemented major reforms to its teacher evaluation system...

DESIGN: Randomized controlled experimental study. SETTING: Local community welfare center. SUBJECTS: A total of 78 subjects with mild cognitive impairment (MCI) were randomly assigned to the NCT ( n = 39) or CCT group ( n = 39).

Therapeutic drug monitoring (TDM) is the clinical practice of measuring pharmaceutical drug concentrations in patients' biofluids at designated intervals to allow a close and timely control of their dosage. This practice allows for rapid medical intervention in case of toxicity-related issues and/or adjustment of dosage to better fit the therapeutic demand. Currently, TDM is performed in centralized laboratories employing instruments, such as immunoassay analyzers and mass spectrometers that can be run only by trained personnel...

High-throughput phenotyping (HTP) platforms can be used to measure traits that are genetically correlated with wheat ( L.) grain yield across time. Incorporating such secondary traits in the multivariate pedigree and genomic prediction models would be desirable to improve indirect selection for grain yield. In this study, we evaluated three statistical models, simple repeatability (SR), multitrait (MT), and random regression (RR), for the longitudinal data of secondary traits and compared the impact of the proposed models for secondary traits on their predictive abilities for grain yield...

BACKGROUND: Functional magnetic resonance imaging (fMRI) is a promising method for quantifying brain recovery and investigating the intervention-induced changes in corticomotor excitability after stroke. This study aimed to evaluate cortical reorganization subsequent to virtual reality-enhanced treadmill (VRET) training in subacute stroke survivors. METHODS: Eight participants with ischemic stroke underwent VRET for 5 sections per week and for 3 weeks. fMRI was conducted to quantify the activity of selected brain regions when the subject performed ankle dorsiflexion...

Hotspot residues are important in the determination of protein-protein interactions, and they always perform specific functions in biological processes. The determination of hotspot residues is by the commonly-used method of alanine scanning mutagenesis experiments, which is always costly and time consuming. To address this issue, computational methods have been developed. Most of them are structure based, i.e., using the information of solved protein structures. However, the number of solved protein structures is extremely less than that of sequences...

BACKGROUND: It has been argued that UK general practice specialist training should be extended to better prepare GPs for the challenges facing 21st-century health care. Evidence is needed to inform how this should occur. AIM: To investigate the experience of recently trained GPs undertaking a 1-year full-time fellowship programme designed to provide advanced skills training in urgent care, integrated care, leadership, and academic practice; and its impact on subsequent career development...

PURPOSE: Caring for children with acute lymphoblastic leukemia (ALL) is a distressing experience for parents without medical training. The experience can lead to parents' care burden. This study explored care burden among parents of children with ALL and its related factors. METHODS: A total of 130 parents were surveyed with the Zarit Burden Inventory (ZBI), Perceived Social Support Scale (PSSS), Zung's Self-rating Anxiety Scale (SAS), Zung's Self-rating Depression Scale (SDS), Medical Outcome Study Short Form 36 (SF-36), and a study specific demographic information questionnaire...

OBJECTIVE: We introduced a live animal model for training of minimally invasive implantation of a continuous-flow left ventricular assist device (CF-LVAD) without cardiopulmonary bypass for operator's performance improvement. DESIGN: After watching a videotape of LVAD implantation on the beating heart through the cardiac apex, the surgical team performed implantation of LVADs into 5 pigs during 3 training sessions in a time series. The procedure success rate, operating time, and technical and global performances by self-evaluation and senior evaluation were compared among the sessions...

BACKGROUND: NHS specialist chronic fatigue syndrome (CFS/ME) services in England treat approximately 8000 adult patients each year. Variation in therapy programmes and treatment outcomes across services has not been described. METHODS: We described treatments provided by 11 CFS/ME specialist services and we measured changes in patient-reported fatigue (Chalder, Checklist Individual Strength), function (SF-36 physical subscale, Work & Social Adjustment Scale), anxiety and depression (Hospital Anxiety & Depression Scale), pain (visual analogue rating), sleep (Epworth, Jenkins), and overall health (Clinical Global Impression) 1 year after the start of treatment, plus questions about impact of CFS/ME on employment, education/training and domestic tasks/unpaid work...

BACKGROUND: Despite being a recessive trait, the O blood group is the most frequent worldwide among the ABO blood types. Since running performance has been recognized as a major driver of evolutionary advantage in humans, we planned a study to investigate whether the ABO blood group may have an influence on endurance running performance in middle-aged recreational athletes. METHODS: The study population consisted of 52 recreational, middle-aged, Caucasian athletes (mean age: 49±13 years, body mass index, 23...

BACKGROUND: To assess the feasibility of texture analysis (TA) based on spectral attenuated inversion-recovery T2 weighted magnetic resonance imaging (SPAIR T2W-MRI) for the classification of hepatic hemangioma (HH), hepatic metastases (HM) and hepatocellular carcinoma (HCC). METHODS: The SPAIR T2W-MRI data of 162 patients with HH (n=55), HM (n=67) and HCC (n=40) were retrospectively analyzed. We used two independent cohorts for training (n = 112 patients) and validation (n = 50 patients)...

The aim of this study was to describe and compare the distances and displacement speeds of U12 Soccer-7 athletes during four tournament Soccer-7 games (TG) played in less than 24-h (experimental condition) with those recorded during two league Soccer-7 games (LG) with 24-h of rest prior to the match (control condition). Ten participants (age = 10.3 ± 0.5 years) were recruited for the study. Main data analyzed during games included distance completed relative to match duration (Drel), maximal velocity and distance completed at different running speeds (including acceleration, deceleration, standing, walking, jogging, medium-intensity running, high-intensity running and sprinting)...
