Bioreactors are essential enabling technologies for the translation of Advanced Therapies Medicinal Products (ATMPs) from the research field towards a successful clinical application. In order to speed up the translation and the spreading of novel Tissue Engineering (TE) products into the clinical routine, TE bioreactors should evolve from laboratory prototypes towards industrialized products. In this work, we thus challenged the industrialization process of a novel technological platform, based on an established research prototype of perfusion bioreactor, following a GMP-driven approach...

Monopolar mapping of motor function differs from the most commonly used method of intraoperative mapping, i.e. bipolar direct electrical stimulation at 50-60Hz (Penfield technique mapping). Most importantly, the monopolar probe emits a radial, homogenous electrical field different to the more focused inter-tip bipolar electrical field. Most users combine monopolar stimulation with the short train technique, also called high frequency stimulation, or train-of-five techniques. It consists of trains of four to nine monopolar rectangular electrical pulses of 200-500μs pulse length with an inter stimulus interval of 2-4msec...

Sitting is part of our daily work and leisure activities and can be performed in different configurations. To date, the impact of different sitting configurations on hip joint loading has not been studied. We therefore evaluated the hip joint reaction force (HJRF) and hip flexion angle in a virtual representative male Caucasian population by means of musculoskeletal modelling of three distinct sitting configurations: a simple chair, a car seat and a kneeling chair configuration. The observed median HJRF in relation to body weight and hip flexion angle, respectively, was 22...

Adrenal tumors can vary from a benign adrenocortical adenoma with no hormonal secretion to a secretory adrenocortical malignancy (adrenocortical carcinoma) or a hormone-secreting tumor of the adrenal medulla (pheochromocytoma). Currently, laparoscopic adrenalectomy is regarded as the preferred surgical approach for the management of most adrenal surgical disorders, although there are no prospective randomized trials comparing this technique with open adrenalectomy. However, widespread adoption of robotic technology has positioned robotic adrenalectomy as an option in some medical centers...

INTRODUCTION: Night-shift works are basically accompanied by reduced cognitive performance, sleepiness, and higher possibility for human error and related incidents. It is therefore crucial to improve individuals' performance and alertness in sensitive places like industries' control room with the ultimate goal of increasing efficiency and reducing the number of possible incidents. Previous research has indicated that blue light is a critical cue for entraining circadian rhythm. As a result, the present study was an attempt to investigate whether blue-enriched white light illumination was a practical strategy to decrease sleepiness and improve cognitive performance during night shifts...

Recently, 2D/3D switchable displays have become the mainstream in 3D display technologies, and people can now watch 3D movies with a naked 2D/3D switchable display at home. However, some studies have indicated that people might encounter visual fatigue after enjoying a 3D film in the theater. Although 2D/3D switchable technologies have been widely developed, 3D display technologies are still lacking in ergonomic and human-care factors such as reducing visual fatigue. This study proposes a novel 2D/3D display auto-adjustment switch system to provide biofeedback functions to reduce users' visual fatigue...
