Advanced Materials, EarlyView.The development of hydrogel‐impregnated robust interlocking nano connector (HiRINC) aims to address stent migration by improving tissue adhesion and reducing mechanical mismatch in self‐expandable metallic stents (SEMSs). The network‐like porous layer of HiRINC enhances adhesion and energy dissipation, demonstrates through ex vivo and in vivo tests ...

Patient specific numerical simulation of flow in the human upper airways for assessing the effect of nasal surgery [PDF]
arXiv, 2017 The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative computed tomography (CT) of an OSAS patient, the pre- and post-operative geometries of the patient's upper airways were generated ...

Nasal irrigation delivery in three post-FESS models from a squeeze-bottle using CFD [PDF]
arXiv, 2022 Purpose: Nasal saline irrigation is highly recommended in patients following functional endoscopic sinus surgery (FESS) to aid the postoperative recovery. Post-FESS patients have significantly altered anatomy leading to markedly different flow dynamics from those found in pre-op or non-diseased airways, resulting in unknown flow dynamics. Methods: This

On the Relentless Pursuit of an Oral Insulin Delivery System: How Far is Too Far?
Advanced Therapeutics, EarlyView.Injectable insulin preparations have far outpaced oral ones by virtue of adequate bioavailability and are driven by innovations, including insulin pumps, real‐time blood glucose monitoring, and artificial intelligence. In contrast, oral insulin delivery systems, including nanomedicines, continue to struggle and lag due to varied reasons.

Inhalable Hsa‐miR‐30a‐3p Liposomes Attenuate Pulmonary Fibrosis
Advanced Science, EarlyView.The study explores inhalable hsa‐miR‐30a‐3p‐loaded liposomes as a treatment for bleomycin‐induced pulmonary fibrosis in mice. Hsa‐miR‐30a‐3p is electroporated into liposomes and formulated into a dry powder for inhalation. Delivered via dry powder inhalation, it improves pulmonary function, promotes myofibroblast de‐differentiation by targeting CNPY2 ...

Automated Objective Surgical Skill Assessment in the Operating Room Using Unstructured Tool Motion [PDF]
arXiv, 2014 Previous work on surgical skill assessment using intraoperative tool motion in the operating room (OR) has focused on highly-structured surgical tasks such as cholecystectomy. Further, these methods only considered generic motion metrics such as time and number of movements, which are of limited instructive value.
