We report here the design and multiple functions of a new hierarchical nanotheronostic platform consisting of an upconversion nanoparticle (UCNP) core: shell with an additional mesoporous silica (mSiO2) matrix load shell containing sealed, high concentration of ICG molecules. We demonstrate that this UCNP@mSiO2-ICG nanoplatform can perform the following multiple functions under NIR excitation at 800 nm: 1) Light harvesting by the UCNP shell containing Nd and subsequent energy transfer to Er in the Core to produce efficient green and red upconversion luminescence for optical imaging; 2) Efficient nonradiative relaxation and local heating produced by concentration quenching in aggregated ICG imbedded in the mesopourous silica shell to enable both photoacoustic imaging and photothermal therapy...

The chimney technique can be combined with thoracic endovascular aortic repair (TEVAR) to both obtain an appropriate landing zone and maintain blood flow of the arch vessels. However, surgical repair becomes more complicated if retrograde type A aortic dissection occurs after TEVAR with the chimney technique. We herein report a case involving a 73-year-old woman who developed a retrograde ascending dissection 3 months after TEVAR for acute type B aortic dissection. To ensure an adequate proximal sealing distance, the proximal edge of the stent graft was located at the zone 2 level and an additional bare stent was placed at the left subclavian artery (the chimney technique) at the time of TEVAR...

AIM: Platelet-rich plasma (PRP), which is a concentration of growth factors found in platelets, may be a suitable material for pulp regeneration. The aim of this animal study was a histological evaluation of PRP on pulp regeneration in nonvital teeth with immature apices. MATERIALS AND METHODS: A total of 40 premolar dogs' teeth were chosen for this study. After general anesthesia, the teeth were exposed, and subsequently, pulps were removed and the cavities were opened to the oral cavity...

Intraoperative bleeding is one of the main severe complications in complete video-assisted thoracic surgery (c-VATS) and post-operative air-leaks prevention still represents an important challenge. Usually, hemostasis is often difficult and unsafe when the VATS approach is performed and the potential role of bipolar sealing devices is still undefined, as proven by limited experiences reported in the literature. By introducing endostaplers in VATS surgery, it was possible to perform safe thoracoscopic resections of lung...

Artificial assembly of mature tissues in vitro is challenging from many viewpoints. Therefore, production of intermediate building blocks - cell spheroids expected to be a viable alternative. The purpose of this research is to develop a biomimetic system for scale up maintenance of spheroids in vitro, and to confirm basic performance of the device. The system consists of a 3D culture unit and a medium perfusion unit. The 3D culture unit is dedicated for spheroid culture without using scaffolds, eliminating concerns about biocompatibility of artificial materials...

Water storage is thought to play an integral role in the maintenance of whole plant water balance. The contribution of both living and dead cells to water storage can be derived from rehydration and pressure-volume curves on excised plant material, but the underlying tissue-specific emptying/refilling dynamics remain unclear. Here, we used X-ray computed micro-tomography (microCT) to characterize refilling of xylem fibers, pith cells and vessels under both excised and in-vivo conditions in Laurus nobilis. In excised stems supplied with H2O, water uptake exhibited a biphasic response curve, and microCT images showed that high water storage capacitance was associated with fiber and pith refilling as driven by capillary forces; fibers refilled more rapidly than pith cells while vessel refilling was minimal...

Despite being the most common training model for endoscopic vein harvesting, cadaveric legs are limited by their absence of blood flow, resulting in a faded vascular appearance. Because the saphenous vein and the surrounding tissue seem less distinguishable, dissection of the saphenous vein and bipolar coagulation of its branches becomes increasingly inefficient and difficult. An inexpensive artificial blood flow system was developed to overcome this limitation. A cadaveric leg was thawed to a soft and yielding degree, and the saphenous vein was dissected medial and proximal to the medial malleolus...

INTRODUCTION: Since the advent of laparoscopy there have been attempts to minimize abdominal wall incisions. For this purpose smaller instruments have been produced. Our aim was to develop the first 3 mm percutaneous clip applier and to make it better than the standard clips of today. MATERIAL AND METHODS: The ClipTip clip is made of Nitinol and has a crocodile shaped jaws, which when apposed effectively seal vessels. The shaft operates as a retractable needle permitting percutaneous insertion...

This study was designed to assess the efficacy of vacuum sealing drainage (VSD) on skull exposure wounds in rabbits and to investigate the underlying mechanism of the process. Full-thickness excisional circular wounds 2×2 cm with or without periosteum involvement were created in 88 New Zealand white rabbits (mean body weight: 3.0±0.65 kg). Animals were randomly divided into 4 groups: periosteum-intact wounds treated with traditional dressing (p+control), periosteum-intact wounds treated with VSD (p+VSD), periosteum-lacking wounds treated with traditional dressing (p-control) and periosteum-lacking wounds treated with VSD (p-VSD)...

INTRODUCTION: Seroma is defined as collection of fluid within the surgical site during postoperative period that causes several complications. Recognition of predisposing risk factors can lead to avoid seroma formation after thyroidectomy. MATERIALS AND METHODS: A cross-sectional study was carried out during a 3-year period and 678 patients were enrolled the study. We recorded demographic data, past medical history and the type of thyroidectomy were for all patients...

Phycocyanins from cyanobacteria are possible sources for new natural blue colourants. Their chromophore, phycocyanobilin (PCB), was cleaved from the apoprotein by solvolysis in alcohols and alcoholic aqueous solutions. In all cases two PCB isomers were obtained, while different solvent adducts were formed upon the use of different reagents. The reaction is believed to take place via two competing pathways, a concerted E2 elimination and a SN2 nucleophilic substitution. Three cleavage methods were compared in terms of yield and purity: conventional reflux, sealed vessel heated in an oil bath, and microwave assisted reaction...

OBJECTIVE: The aim of our study was to evaluate the feasibility of vaginal hysterectomy in an ambulatory care system and the best way to perform it between conventional and bipolar vessel sealing system ligatures. PATIENTS AND METHODS: This was a prospective study of 32 patients with vaginal hysterectomy at Lille University Hospital between December 2013 and May 2015.

BACKGROUND: Bipolar vessel sealing has been successfully introduced in a variety of procedures like prostatectomy, hysterectomy, and nephrectomy. In this study, we evaluated a new sealing mode-the thermoSEAL(®) mode (TSM)-operated with the VIO3 generator in an ex vivo and in vivo animal study and compared the results with the commercially available BiClamp mode (BCM), operated with the VIO300D generator. Two different instruments were used in combination with both modes, BiCision(®) and BiClamp(®) 201T (Erbe Elektromedizin GmbH)...

PURPOSE: To determine how many endovascular aneurysm sealing (EVAS) procedures with/without off-label use of chimneys (ChEVAS) could have been performed in a cohort of patients who had undergone fenestrated endovascular aneurysm repair (FEVAR). METHODS: Sixty patients (median age 76.3 years; 54 men) who underwent FEVAR in our institution between 2013 and 2015 were selected for the study. The median aneurysm diameter was 62.0 mm (interquartile range 59.3, 69.0). Preoperative computed tomography angiograms (CTA) were anonymized and sent to 2 physicians with experience of more than 40 ChEVAS interventions...

Economic losses in a range of fruit crops due to the Drosophila suzukii (Matsumura) have become severe. Removal and treatment of fruit waste, which may harbor D. suzukii, is a key step in preventing reinfestation of fruit production. Natural fermentation for disinfesting fruit wastes from D. suzukii was examined at ambient air temperatures of 12-20 °C. Soft and stone fruit wastes infested with eggs, larvae, and pupae of Drosophila melanogaster (Meigen) or D. suzukii were placed in sealed vessels containing fruit wastes, and samples were retrieved at intervals and tested for the emergence of adults...
