73 ± .09). Accuracy ranged between 0.65 and 0.93 based on varying repetition rate and duty cycle.<br /><br /> Hand posture and force prediction were possible using sEMG and ANNs, though there were important differences in the accuracy of predictions based on task characteristics including duty cycle and repetition rate.<br /><br /> The results of this study could be applied to the development of a dosimeter used for distal upper extremity biomechanical exposure measurement, risk assessment, job (re)design, and return to work programs.<br /><br />The results of this study could be applied to the development of a dosimeter used for distal upper extremity biomechanical exposure measurement, risk assessment, job (re)design, and return to work programs.Glioblastoma, the deadliest form of primary brain tumor, remains a disease without cure. Treatment resistance is in large part attributed to limitations in the delivery and distribution of therapeutic agents. Over the last 20 years, numerous preclinical studies have demonstrated the feasibility and efficacy of stem cells as antiglioma agents, leading to the development of trials to test these therapies in the clinic. In this review we present and analyze these studies, discuss mechanisms underlying their beneficial effect and highlight experimental progress, limitations and the emergence of promising new therapeutic avenues. We hope to increase awareness of the advantages brought by stem cells for the treatment of glioblastoma and inspire further studies that will lead to accelerated implementation of effective therapies.<br /><br /> To study the effects of age on the olfactory function recovery of chronic rhinosinusitis patients after endoscopic sinus surgery and related risk factors.<br /><br /> A total of 176 chronic rhinosinusitis (CRS) patients enrolled from February 2017 to October 2019 were divided into child, youth, middle-aged, and elderly groups. Their baseline data, T&amp;T olfactory test score, visual analogue scale (VAS) olfactory score, sinus computed tomography (CT) Lund-Mackay score, and Lund-Kennedy score were compared. Based on postoperative olfactory function, they were divided into good and poor improvement groups.<br /><br /> Complication with nasal polyps, allergic rhinitis history, and sinus surgery history had significant differences among patients of different ages (<br /><br /> &lt; .05). Three months after surgery, T&amp;T olfactory, VAS olfactory, Lund-Mackay, and Lund-Kennedy scores all rose with increasing age, with significant differences between any 2 groups (<br /><br /> &lt; .05). The improvement of postoperative olfactory function became pooative Lund-Mackay and Lund-Kennedy scores, complication with nasal polyps, allergic rhinitis history, sinus surgery history, and postoperative complications are risk factors for the poor improvement of postoperative olfactory function. Doctor-directed treatment is a protective factor for good improvement.Background Ruptured juxtarenal aortic aneurysms (RJAAA) represent a special challenge in clinical practice, but the evidence to guide therapeutic decision-making is scarce. The aim of this study was to present two different approaches, open surgical (OAR) and chimney endovascular repair (CHEVAR), for treating patients with RJAAA. Patients and methods This retrospective two-center study included all patients per center undergoing OAR or CHEVAR for RJAAA between February 2008 and January 2020. Juxtarenal aortic aneurysms were defined as having an infrarenal neck of 2-5 mm, measured after three-dimensional reconstruction of the computed tomography angiography scan. Results 12 OAR patients (10 male, median age 73 years [58-90 years]) and 6 CHEVAR patients (all male, median age 74 years [59-83 years]) were included. In the OAR group, the proximal aortic clamping was suprarenal in 7 and interrenal in 5 patients. Cold renal perfusion was used in 4 patients, in 2 with suprarenal aortic clamping and in 2 with interrenal aortic clamping. 3 CHEVAR patients received a single renal chimney, the other 3 received double renal chimneys. Technical success was 12/12 in the OAR group 5/6 in the CHEVAR group. In-hospital mortality and 30-day mortality were 3/12 after OAR and 0/6 after CHEVAR. 2 OAR patients required transient dialysis. Median in-hospital stay was 14 (10-63) and 8 (6-21) days and median follow-up (FU) was 20 (3-37) and 30 (7-101) months, respectively. No further deaths occurred during FU. One OAR patient and 4 CHEVAR patients required aortic reinterventions. Conclusions RJAAAs are rare. Both OAR and CHEVAR can represent adequate treatments for RJAAAs. OAR is the traditional approach, but CHEVAR has - in a high-volume center - promising early results with nonetheless a need for continuous FU to prevent reinterventions. Defining the studied aortic pathology precisely is essential for future research in order to draw valid conclusions.Physical activity improves quality of life and extends independence in older adults. Yet, how to motivate older adults to engage in physical activity is unclear. [https://www.selleckchem.com/products/abr-238901.html Selleckchem ABR-238901] In the present study, 4108 older women, aged 70-99, reported how they motivated themselves to move when they did not feel like it, and their hours of physical activity and walking each week. Findings indicated that participants who endorsed more strategies had more hours of physical activity and walking. Strategic categories that correlated with more physical activity include focusing on the benefits and utilizing the surrounding environment to help motivate movement.<br /><br /> Developing and validating a novel domain-agnostic, computer-based training tool for enhancing 2D cross-section understanding of complex 3D structures.<br /><br /> Understanding 2D cross-sections of 3D structures is a crucial skill in many disciplines, from geology to medical imaging . It requires a complex set of spatial/visualization skills including mental rotation, spatial structure understanding, and viewpoint projection. Prior studies show that experts differ from novices in these skills.<br /><br /> We have developed a novel training tool for inferring 2D cross-sections of 3D structures using a participatory design methodology. We used a between-subject study design, with 60 participants, to evaluate the training tool. Our primary effectiveness evaluation was based on pre- and postspatial tests that measured both cross-section abilities and specific spatial skills viewpoint, mental rotation, and card rotation.<br /><br /> Results showed significant performance gains on inferring 2D cross-sections for participants of the training group.
