The cell-penetrating peptide (CPP) penetratin, has demonstrated potential as a carrier for transepithelial delivery of cargo peptides, such as the therapeutically relevant part of parathyroid hormone, i.e. PTH(1-34). The purpose of the present study was to elucidate the relevance of modifying the pH for PTH(1-34)-penetratin conjugates and for co-administered penetratin with PTH(1-34) in terms of transepithelial permeation of PTH(1-34) and cellular effects. Transepithelial permeation was assessed using monolayers of the Caco-2 cell culture model, and effects on Caco-2 cellular viability kinetics were evaluated by using the Real-Time-GLO assay as well as by microscopy following Tryphan blue staining...

Anaplastic lymphoma kinase (ALK) rearrangement is most commonly observed in lung adenocarcinoma in a subset of lung cancer. Large-cell neuroendocrine carcinoma (LCNEC) harboring an ALK rearrangement is very rare. Based on the findings from a transbronchial lung biopsy, a 75-year-old non-smoking woman was diagnosed with LCNEC with multiple liver and bone metastases. After seven cycles of cytotoxic chemotherapy, her genotype testing demonstrated ALK rearrangement. Subsequently, she was administered alectinib and exhibited a partial response...

An all-dielectric optical antenna supporting Mie resonances enables light confinement below the free-space diffraction limit. The Mie scattering wavelengths of the antenna depend on the structural geometry, which allows the antennas to be used for colored imprint images. However, there is still room for improving the spatial resolution, and new polarization-dependent color functionalities are highly desirable for realizing a wider color tuning range. Here, we show all-dielectric color printing by means of dual-color pixels with a subwavelength-scale resolution...

PURPOSE: Three-dimensional reconstruction of a vessel centerline from paired planar coronary angiographic images is critical to reconstruct the complex three-dimensional structure of the coronary artery lumen and the relative positioning of implanted devices. In this study, a new vessel centerline reconstruction method that can utilize non-isocentric and non-orthogonal pairs of angiographic images was developed and tested. METHODS: Our new method was developed in in vitro phantom models of bifurcated coronary artery with and without stent, and then tested in in vivo swine models (twelve coronary arteries)...

Tributyltin (TBT) has been recognized as an endocrine disrupting chemical (EDC) for several decades. However, only in the last decade, was its primary endocrine mechanism of action (MeOA) elucidated-interactions with the nuclear retinoid-X receptor (RXR), peroxisome proliferator-activated receptor γ (PPARγ), and their heterodimers. This molecular initiating event (MIE) alters a range of reproductive, developmental, and metabolic pathways at the organism level. It is noteworthy that a variety of MeOAs have been proposed over the years for the observed endocrine-type effects of TBT; however, convincing data for the MIE was provided only recently and now several researchers have confirmed and refined the information on this MeOA...

The monitor of sea fogs become more important with the rapid development of marine activities. Remote sensing through laser is an effective tool for monitoring sea fogs, but still challengeable for large distance. We demonstrated a Long-distance Lidar for sea fog with superconducting nanowire single-photon detector (SNSPD), which extended the ranging area to a 180-km diameter area. The system, which was verified by using a benchmark distance measurement of a known island, is applied to the Mie scattering weather prediction Lidar system...

The exact suppression of backscattering from rotationally symmetric objects requires dual symmetric materials where ε r = μ r. This prevents their design at many frequency bands, including the optical one, because magnetic materials are not available. Electromagnetically small non-magnetic spheres of large permittivity offer an alternative. They can be tailored to exhibit balanced electric and magnetic dipole polarizabilities a 1 = b 1, which result in approximate zero backscattering. In this case, the effect is inherently narrowband...

Many applications of nano- and microparticles require molecular functionalization. Assessing the heterogeneity of a colloidal sample in terms of its molecular functionalization is highly desirable, but not accessible by conventional ensemble experiments. Retrieving this information necessitates single-particle experiments which simultaneously detect both functionalized and non-functionalized particles via two separate imaging channels. In this contribution, we present an optical setup for performing correlative single-particle imaging using laser light-sheet illumination: the first detection channel records elastic light scattering (Rayleigh/Mie), while the second channel detects inelastic light scattering (Raman) or fluorescence...

The inerting effect of crystalline II type Ammonium Polyphosphate (APP-II) on explosion characteristics of micron-size Acrylates Copolymer (ACR) powders was experimentally studied. The inerting mechanism was analysed by combining thermogravimetry (TG) and differential scanning calorimetry (DSC) tests. The results indicated that the maximum explosion pressure (Pmax) and explosion index (Kst) was 10.4bar and 416bar m/s, respectively for ACR powders. The minimum explosion concentration (MEC) of ACR powders ranged from 20 to 30g/m(3), and the experimental minimum ignition energy (MIE) of the ACR dust cloud was 10mJ...

Imaging and chromosome conformation capture studies have revealed several layers of chromosome organization, including segregation into megabase-sized active and inactive compartments, and partitioning into sub-megabase domains (TADs). It remains unclear, however, how these layers of organization form, interact with one another and influence genome function. Here we show that deletion of the cohesin-loading factor Nipbl in mouse liver leads to a marked reorganization of chromosomal folding. TADs and associated Hi-C peaks vanish globally, even in the absence of transcriptional changes...

Mutations generate genetic variation and are a major driving force of evolution. Therefore, examining mutation rates and modes are essential for understanding the genetic basis of the physiology and evolution of organisms. Here, we aim to identify germline de novo mutations through the whole-genome surveyance of Mendelian inheritance error sites (MIEs), those not inherited through the Mendelian inheritance manner from either of the parents, using ultra-deep whole genome sequences (>150-fold) from a chimpanzee parent-offspring trio...

BACKGROUND: Minimally invasive esophagectomy (MIE) is increasingly performed worldwide. Unplanned events during thoracoscopy or laparoscopy can jeopardize the procedure, sometimes necessitating conversion to open surgery. The aim of this study was to evaluate the impact of unplanned events on early postoperative outcomes after MIE. METHOD: A consecutive group of 303 patients who underwent MIE between January 2011 and December 2015 were reviewed. The patients were allocated to two groups comprising those with (G-UPE, 85 patients) and without unplanned events (G-Regular, 218 patients)...

Esophageal cancer is the eight most common cancer in the world and surgical resection remains the gold standard not only in providing the optimal chance for cure but also the best palliation for dysphagia. Esophagectomy is a complex operation and is associated with significant morbidity and mortality that are reported as 23-50% and 2-8% in western country. At the moment no gold standard techniques exist for esophagectomy. The choice of the technique depends on several factors; location of tumor and surgeon's experience are probably the most relevant...

Minimally invasive esophagectomy (MIE) has gained popularity over the last two decades as an oncologically sound alternative to open esophagectomy. Robotic assisted minimally invasive esophagectomy (RAMIE) has been developed at few highly-specialized centers, and overall experience with this technique remains limited. Herein, we describe our overall approach to this operation and specific technical issues.
