INTRODUCTION: Patients with esophageal cancer frequently cannot tolerate thoracotomy due to their overall debilitated condition. Moreover, some patients have severe adhesions in the thoracic cavity. Eversion stripping of the esophagus is an option for resection in these patients. PRESENTATION OF CASE: A 64-year-old man was admitted to our institution with the chief complaint of epigastric pain. Endoscopic examination showed a protruding lesion 22cm from the incisors, with a superficial and circumferential mucosal irregularity on the distal side of the lesion...

Thoracic aortic aneurysm (TAA) is a genetic disease predisposing to aortic dissection. It is important to identify the genetic modifiers controlling penetrance and expressivity to improve clinical prognostication. Exome sequencing was performed in 27 subjects with syndromic or familial TAA presenting with extreme phenotypes (15 with severe TAA; 12 with mild or absent TAA). Family-based analysis of a subset of the cohort identified variants, genes, and pathways segregating with TAA severity among three families...

OBJECTIVE: The aim of this study was to investigate the value of [18F]fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in predicting lymph node status in node-negative endometrial cancer on preoperative magnetic resonance imaging (MRI). METHODS: Patients with endometrial cancer who underwent both preoperative MRI and FDG-PET/CT followed by hysterectomy and lymphadenectomy were initially included. We then enrolled patients with MRI-defined node-negative disease (lymph nodes <1 cm in the short-axis diameter, or no visible lymph node)...

Prolyl oligopeptidase (PREP) is conserved in many organisms across life. It is involved in numerous processes including brain function and neuropathology, that require more than its strict proteolytic role. It consists of a seven-bladed β-propeller juxtaposed to a catalytic α/β-hydrolase domain. The conformational dynamics of PREP involved in domain motions and the gating mechanism that allows substrate accessibility remain elusive. Here we used Hydrogen Deuterium eXchange Mass Spectrometry (HDX-MS) to derive the first near-residue resolution analysis of global PREP dynamics in the presence or absence of inhibitor bound in the active site...

Mutations in lysyl oxidase (LOX) are associated with thoracic aortic aneurysm and dissection (TAAD). Mice that do not express Lox (Lox(-/-)) die soon after birth and have 60% and 40% reductions in elastin- and collagen-specific crosslinks, respectively. LOX inactivation could also change the expression of secreted factors, structural matrix, and matrix-associated proteins that constitute the aortic matrisome. We hypothesize that the absence of Lox will change the mechanical behavior of the aortic wall due to reduced elastin and collagen crosslinking and alter the expression levels of matrisome and smooth muscle cell (SMC) genes in a vascular location-specific manner...

How essential, regulatory genes originate and evolve is intriguing because mutations of these genes not only lead to lethality in organisms, but also have pleiotropic effects since they control the expression of multiple downstream genes. Therefore, the evolution of essential, regulatory genes is not only determined by genetic variations of their own sequences, but also by the biological function of downstream genes and molecular mechanisms of regulation. To understand the origin of essential, regulatory genes, experimental dissection of the complete regulatory cascade is needed...

BACKGROUND: Graph theory is widely used to dissect structural communication in biomolecular systems. Here, graph theory-based approaches were applied to the headpiece of integrins, adhesion cell-surface receptors that transmit signals across the plasma membranes. METHODS: Protein Structure Network (PSN) analysis incorporating dynamic information either from molecular dynamics simulations or from Elastic Network Models was applied to the β3 domains from integrins αVβ3 and αIIbβ3 in their apo and ligand-bound states...

The trochlear nerve is generally considered to be a purely motor nerve supplying one extraocular muscle, the superior oblique. In the current study, 28 orbits were dissected and in one orbit (3.6%), the trochlear nerve divided into two main branches. The medial branch followed the classical course, entered the superior oblique muscle and was presumed to be motor in function. However, before entering the muscle, it partially fused with the frontal nerve, and gave a bundle of nerve fibres to the frontal nerve...

BACKGROUND: The role of axillary lymph node dissection (ALND) has increasingly been called into question among patients with positive sentinel lymph nodes. Two recent trials have failed to show a survival difference in sentinel node-positive breast cancer patients who were randomized either to undergo completion ALND or not. Neither of the trials, however, included breast cancer patients undergoing mastectomy or those with tumors larger than 5 cm, and power was debatable to show a small survival difference...

Cystic hygroma is a benign tumor of lymphatic tissue. It usually develops before the second year of life and is rarely seen in adults. A 26-year-old woman was referred to our clinic with a swelling in the left supraclavicular region, which had appeared 5 months earlier and grown rapidly. Ultrasonography, computed tomography, and magnetic resonance imaging showed a 7-cm cystic lesion in the neighborhood of the carotid artery and jugular vein medially and the supraclavicular region inferiorly The lesion was dissected completely from the surrounding tissue...

Fluorescent dyes are commonly used in the sterile insect technique (SIT) for marking insects for a proper identification after recapture. However, the quality of the mark must be balanced against insect performance, because dyes can negatively affect some parameters of insect performance and reduce their effectiveness in control with the SIT. We determined the visibility and persistence and the effect of dyes on the quality of Anastrepha obliqua (Macquart) and Anastrepha ludens (Loew) (bisexual and genetic sexing strains) by testing four concentrations of a dye (Day-Glo) from 0 to 2...

The patient was a 67-year-old woman with a history of advanced lung adenocarcinoma. Eight days after pegfilgrastim administration, her computed tomography scan revealed thickened bilateral common carotid arteries and thoracic aorta, which led to the diagnosis of pegfilgrastim-associated aortitis. Thirty-six days after pegfilgrastim administration, asymptomatic Stanford type B aortic dissection was detected. Her serum biomarker analysis suggested that interleukin-6 might be involved in the pathogenesis. Physicians should be aware of these adverse effects of filgrastim...

OBJECTIVE: Although the benefits of minimally invasive valvular surgery are well established, the applicability of extending these techniques to reoperative aortic valve surgery is unknown. We evaluated our experience with a minimally invasive approach to this patient population. METHODS: From January 2010 to September 2015, 21 patients underwent reoperative isolated aortic valve replacement via a minimally invasive approach by a single surgeon. All patients had preoperative evaluation with computerized tomography and coronary catheterization...

The pluripotency transcriptional network in embryonic stem cells (ESCs) is composed of distinct functional units including the core and Myc units. It is hoped that dissection of the cellular functions and interconnections of network factors will aid our understanding of ESC and cancer biology. Proteomic and genomic approaches have identified Nac1 as a member of the core pluripotency network. However, previous studies have predominantly focused on the role of Nac1 in psychomotor stimulant response and cancer pathogenesis...

This analysis compared the angiographic outcomes of patients treated with orbital atherectomy for calcified common femoral artery (CFA) and superficial femoral artery (SFA) disease. The ideal revascularization strategy for CFA disease is unknown. Endarterectomy has been considered the standard of care for CFA disease for over 50 years. Endovascular intervention is becoming more commonly used to revascularize the CFA given the advances in technology and the less invasive nature of the procedure. Patient demographics, lesion characteristics, and procedure data for all CONFIRM patients with at least one CFA lesion location ( n=147 patients; n=200 lesions) were compared to patients with at least one SFA lesion location ( n=1508 patients; n=2367 lesions)...

We treated a 64-year-old man for rectal cancer with direct invasion to the seminal vesicles and no distant metastases by complete resection with laparoscopy and transanal minimally invasive surgery (TAMIS). We inserted the TAMIS device into the anal canal to above the anorectal ring and dissected to prostate level. High ligation of the inferior mesenteric artery and vein was performed by standard medial laparoscopy. The sigmoid and descending colon were mobilized, and in the postrectal space, we dissected to the space made by TAMIS...
