This study investigated the unique properties, fabrication technique and vascular applications of woven nanotextiles made from low strength nanoyarns, which are bundles of thousands of nanofibers. An innovative robotic system was developed to meticulously interweave nanoyarns in longitudinal and transverse directions, resulting in a flexible, but strong woven product. This is the only technique for producing seamless nanotextiles in tubular form from nanofibers. The porosity and mechanical properties of nanotextiles could be substantially tuned by altering the number of nanoyarns per unit area...

Transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a new approach to the central neck that avoids an anterior cervical incision. This approach can be performed with endoscopic or robotic assistance and offers access to the bilateral central neck. It has been completed safely in both North American and, even more extensively, international populations. With any new technology or approach, complications during the learning curve, expense, instrument limitations, and overall safety may affect its ultimate adoption and utility...

Introduction: Given the ubiquity of robot-assisted laparoscopic prostatectomy (RALP) for treatment of localized prostate cancer, more surgeons are encountering challenging cases, either secondary to difficult anatomy, prior abdominal surgery, or prior radiation therapy. Our case is of RALP in a patient after prior suprapubic prostatectomy. Case Presentation: A 61-year-old otherwise healthy Hispanic gentleman presented for consultation after being found to have Gleason 4 + 4 = 8 prostate cancer on transrectal ultrasound-guided biopsy by an outside provider in July 2017...

BACKGROUND: Positive surgical margins (PSMs) at radical prostatectomy (RP) are generally recognized as a surrogate of poor or difficult dissection of the prostatic gland. In open RP cohorts, obesity seems to be associated to an increased risk of PSMs, probably due to the technical challenge that obese men pose to surgical access. Minimally invasive RP has been claimed to possibly reduce PSM rate. Aim of the study was to explore the impact of obesity and body habitus on PSM risk and their localisation during laparoscopic and robotic-assisted RP...

Robotic transaxillary thyroidectomy, pioneered in South Korea, is firmly established throughout the Far East but remains controversial in Western practice. This relates to important population differences (anthropometry and culture) compounded by the smaller mean size of thyroid nodules operated on in South Korea due to a national thyroid cancer screening programme. There is now level 2 evidence (including from Western World centres) to support the safety, feasibility, and equivalence of the robotic approach to its open counterpart in terms of recurrent laryngeal nerve injury, hypoparathyroidism, haemorrhage, and oncological outcomes for differentiated thyroid cancer...

Robotic parathyroidectomy represents a novel surgical approach in the treatment of primary hyperparathyroidism when the parathyroid adenoma has been pre-operatively localised. It represents the "fourth generation" in the evolution of parathyroid surgery following a process of surgical evolution from cervicotomy and 4-gland exploration to a variety of minimally invasive, open and endoscopic, targeted approaches. The existing evidence (levels 2-3) supports it as a feasible and safe technique with equivalent results to targeted open parathyroidectomy for primary hyperparathyroidism in carefully selected patients...

BACKGROUND: Dexmedetomidine, a selective α2-adrenergic agonist currently approved for continuous intensive care unit sedation, is being widely evaluated for its role as a potential anesthetic. The closed-loop anesthesia delivery system (CLADS) is a method to automatically administer propofol total intravenous anesthesia using bi-spectral index (BIS) feedback and attain general anesthesia (GA) steady state with greater consistency. This study assessed whether dexmedetomidine is effective in further lowering the propofol requirements for total intravenous anesthesia facilitated by CLADS...

An automatic method is established for layer-by-layer (LbL) assembly of biomimetic coatings in cell culture microplates using a commercial liquid-handling robot. Highly homogeneous thin films are formed at the bottom of each microwell. The LbL film-coated microplates are compatible with common cellular assays, using microplate readers and automated microscopes. Cellular adhesion is screened on crosslinked and peptide-functionalized LbL films and stem cell differentiation in response to increasing doses of bone morphogenetic proteins (2, 4, 7, 9)...
