#1
Takuhiro Otosu, Shoichi Yamaguchi
We present standing evanescent-wave fluorescence correlation spectroscopy (SEW-FCS). This technique utilizes the interference of two evanescent waves which generates a standing evanescent-wave. Fringe-pattern illumination created by a standing evanescent-wave enables us to measure the diffusion coefficients of molecules with a super-resolution corresponding to one fringe width. Because the fringe width can be reliably estimated by a simple procedure, utilization of fringes is beneficial to quantitatively analyze the slow diffusion of molecules in a supported lipid bilayer (SLB), a model biomembrane formed on a solid substrate, with the timescale relevant for reliable FCS analysis...

BACKGROUND: Surgical aortic valve replacement (SAVR) is the treatment of choice in severe symptomatic aortic valve disease. New techniques and prostheses have been recently developed to facilitate the procedure and reduce aortic cross-clamp time (AOx). The aim of this study was to analyse the different procedural steps in order to identify the most time-consuming part during aortic clamping time and to compare impact of experience on procedural aspects. METHODS: AOx during SAVR was divided into five consecutive steps...

Aortic aneurysms involving the ascending aorta, aortic arch, and descending thoracic aorta have been a challenging entity to surgically treat for over 60 years. Despite the mortality of the disease, early open surgical procedures also had significant morbidity and mortality. The inherent risk in treating multiple anatomic segments simultaneously led to the innovation of the staged elephant trunk (ET) approach by Borst in 1983. To avoid the thoracotomy and associated complications related to the second stage of the procedure, an endovascular completion paradigm was begun by Volodos in 1991...

Giant left atrial diverticulum is a rare congenital malformation that is most commonly diagnosed in incidental finding. Here, we reported a case of a 1-year-old asymptomatic child with a giant left atrial diverticulum. Diagnosis was established by transthoracic echocardiography (TTE), and confirmed by multidetector computed tomography (MDCT) and transesophageal echocardiography (TEE). We excised the diverticulum and sewed its base under cardiopulmonary bypass and cardiac arrest.  The patient had a good postoperative result...

Phytoplankton-derived dissolved organic matter (PDOM) and macrophyte-derived dissolved organic matter (MDOM) exist ubiquitously in eutrophic freshwater lakes. To understand the heterogeneous roles of individual fluorescent DOM components in the adsorption of antibiotics onto sediment minerals, the adsorptive fractionation of DOM on goethite (α-FeOOH) and its interaction with sulfamethazine (SMT) were investigated using fluorescence excitation-emission matrix combined with parallel factor analysis (EEM-PARAFAC)...

BACKGROUND: We previously reported the use of an inverted T-shaped method to obtain a suitable view for hand sewing to close the common entry hole when the linear stapler was fired for esophagojejunostomy after laparoscopic total gastrectomy (LTG). This conventional method involved insertion of the fixed cartridge fork to the Roux limb and the fine movable anvil fork to the esophagus to avoid perforation of the jejunum. However, insertion of the movable anvil fork to the esophagus during this procedure often requires us to strongly push down the main body of the stapler with the fixed cartridge fork to bring the direction of the anvil fork in line with the direction of the long axis of the esophagus while controlling the opening of the movable anvil fork...

Aortoenteric fistulas (AEF) are a rare but life-threatening cause of gastrointestinal (GI) bleeding. We present the case of a primary AEF caused by ingestion of a toothpick by a 47-year-old male. This is the 10th known case in the literature in which a foreign body was found to be the cause of a communication between the aorta and the GI tract. Most foreign objects have been sewing needles; this is the first known case of a toothpick penetration. The patient presented to our institution with polymicrobial sepsis and bilateral pulmonary septic emboli...

OBJECTIVE: Obtaining the proficiency on the robotic platform necessary to safely perform a robotic pancreatoduodenectomy is particularly challenging. We hypothesize that by instituting a proficiency-based robotic training curriculum we can enhance novice surgeons' skills outside of the operating room, leading to a shorter learning curve. DESIGN: A biotissue curriculum was designed consisting of sewing artificial organs to simulate a hepaticojejunostomy (HJ), gastrojejunostomy (GJ), and pancreaticojejunostomy (PJ)...

Malaria surveillance data provide opportunity to develop forecasting models. Seasonal variability in environmental factors correlate with malaria transmission, thus the identification of transmission patterns is useful in developing prediction models. However, with changing seasonal transmission patterns, either due to interventions or shifting weather seasons, traditional modelling approaches may not yield adequate predictive skill. Two statistical models,a general additive model (GAM) and GAMBOOST model with boosted regression were contrasted by assessing their predictive accuracy in forecasting malaria admissions at lead times of one to three months...

Background: ETV6/RUNX1 gene fusion is the most frequently seen chromosomal abnormality in childhood acute lymphobastic leukamia (ALL). However, additional genetic changes are known to be required for the development of this type of leukaemia. Therefore, we here aimed to assess the somatic mutational profile of four ALL cases carrying the ETV6/RUNX1 fusion gene using whole-exome sequencing. Methods: DNA was isolated from bone marrow samples using a QIAmp DNA Blood Mini kit and subsequently sequenced using the Illumina MiSeq system...

Coronary sinus injury is a very rare complication of cardiac surgery and is usually related to coronary sinus perfusion catheter placement for retrograde cardioplegia infusion. It can be either a catheter-related perforation or high-perfusion pressure-related injury to the coronary sinus. Primary repair of the coronary sinus or over-sewing are two possible options to resolve this complication. Decellularized extracellular matrix from porcine intestinal submucosa is widely used as an approved material for repairing cardiac structures...

BACKGROUND: The occurrence of malignant mesothelioma is almost always causally associated to asbestos exposure but, considering women occurrences, this association is often difficult to demonstrate and consequently the asbestos exposure is defined as 'unknown'. OBJECTIVES: To describe the working activity and to give occupational asbestos exposure probability estimation related to an uncommon and poorly investigated productive sector: doll manufacture. METHODS: From the Province of Brescia Mesothelioma Registry, established in 1993 on population-based criteria, we have extracted the certified mesothelioma diagnosis cases, related to patients who were employed for some time in doll manufacture...

A rare example of highly selective σ N-C bond difunctionalization in bridged twisted lactams through N-C cleavage has been achieved. In combination with the intramolecular Heck cyclization, this method affords a two-step bond reorganization event ("sew-and-cut") to access functionalized isoquinoline ring systems directly with high atom economy. C-H bond functionalizations directed by a weakly coordinating bridged amide bond increase scaffold diversity. Preliminary mechanistic studies on the effect of amide distortion and the role of electrophile in this unusual σ N-C amide difunctionalization are described...
