OBJECTIVES: This study investigated the incidence and clinical significance of arterial graft-associated uptake of fluorodeoxyglucose in large-vessel vasculitis (LVV). BACKGROUND: The role of (18)F-labeled fluorodeoxyglucose-positron emission tomography/computed tomography ([(18)F]FDG-PET/CT) in the management of LVV remains to be defined. Although [(18)F]FDG uptake at arterial graft sites raises concerns regarding active arteritis or infection, its clinical significance in LVV has never been formally studied...

BACKGROUND: The potential survival benefit of bilateral internal thoracic artery (BITA) grafting in patients undergoing off-pump coronary artery bypass graft surgery (OPCABG) is controversial owing to the technical complexity of these operations. Our objective was to compare the outcome of patients undergoing OPCABG with BITA to the outcome of patients undergoing OPCABG with a single internal thoracic artery (SITA) and saphenous vein grafts or radial artery. METHODS: Five hundred and thirty-five consecutive patients who underwent OPCABG BITA at our institute between 2000 and 2008 were compared with 422 patients who underwent OPCABG with SITA...

In this work, a "solvent-free" and green method for controllable and quantitative preparation of chromatographic stationary phase has been proposed. About the method, the largely excess of functional monomer and strict control of the proportion between silane and silica are the two most important points. Due to the existence of excessive functional monomer, silane can be utilized at the maximum extent, thereby achieving quantitative and reproducible bonding. Meanwhile, the excessive monomer can also be well recycled...

Since the 1990s, a large body of literature has been published regarding minimally invasive coronary artery bypass grafting. Varying techniques, complexity of the procedures and the necessity of patient selection have led to its inconsistent application. We describe the standardized technique of left internal mammary artery grafting to the left anterior descending coronary artery, off-pump through a left inferior J-hemisternotomy (JOPCAB). This approach is straightforward, safe, effective, and replicable in virtually all patients...

In this work, we have demonstrated a novel route for one-pot synthesis of two dimensional gold nanoplates (2-D AuNPLs) on carbon nanotube (CNT) sheet. Well-defined AuNPLs are grafted onto CNT sheet via a facile hydrothermal reduction process, during which bromine ions are employed as the surfactant for gold anisotropic growth. Scanning electron microscopy (SEM) shows large-scale AuNPLs with micrometer-scaled length and sub-100 nm thickness are deposited uniformly on the CNT sheet. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) results confirm the synthesized AuNPLs are single-crystalline with preferential {111} orientation...

<p>Successful subretinal transplantation is limited by considerable early graft loss, despite pharmacological suppression of adaptive immunity. We postulated that early innate immune activity is a dominant factor in determining graft survival and chose a non-immunosuppressed mouse model of retinal pigment epithelial (RPE) cell transplantation to explore this.</p><p>Expression of almost all measured cytokines by DH01 RPE cells increased significantly following graft preparation and the neutrophil chemoattractant, KC/GRO/CINC, was most significantly increased...

Dacron grafts have been used as a conduit for large caliber arteries for many years successfully. However, these grafts can undergo complications such as aneurysm formation, rupture, and failure. Evaluation of these complications are of paramount importance because of its tendency to rupture and cause death. Imaging plays an important role in identifying and monitoring of these complications, and also provides a road map to the vascular surgeons for early intervention and revascularization.

OBJECTIVES: The techniques and outcomes of outflow reconstruction in living donor liver transplantation (LDLT) using cryopreserved homologous veins at the University of Tokyo Hospital are presented. METHODS: We performed 540 LDLTs from January 1996 to March 2015. Graft types included right liver graft (n = 262), left liver graft (n = 196), left lateral sector graft (n = 53), and posterior sector graft (n = 28). We routinely use cryopreserved homologous vein grafts for the hepatic vein reconstructions to secure the large outflow of the graft...

Scar contracture deformity, which can lead to dysfunction of hand and low quality of life, is one of the common complication after hand burns. The prevention measures of scar contracture after hand burns include large skin grafting, prevention of infection, insistence on wearing pressure gloves, use of silicone sheets, wearing orthosis, accepting proper physical therapy, and early functional exercise. The primary treatments of postburn contractures of the hand are surgery, drugs, laser treatment, and rehabilitation therapy...

While transplantation represents a key tool for assessing in vivo functionality of neural stem cells and their suitability for neural repair, little is known about the integration of grafted neurons into the host brain circuitry. Rabies virus-based retrograde tracing has developed into a powerful approach for visualizing synaptically connected neurons. Here, we combine this technique with light sheet fluorescence microscopy (LSFM) to visualize transplanted cells and connected host neurons in whole-mouse brain preparations...

BACKGROUND: Total hip arthroplasty is an increasingly common procedure. The large number of cases inevitably includes patients who require filling of their acetabular defect even in their primary surgery. The use of a utogenous grafts and allografts as well as resistance rings requires patients to avoid loading the limb for a long time to enable implant integration. This disadvantage may be partially eliminated by using trabecular titanium implants. The aim of this paper is to present the outcomes of the use of trabecular titanium implants in primary hip arthroplasty...

BACKGROUND: Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized that mucosal thickening would not alter the predictability for sinus floor augmentation and dental implant placement. The purpose of this retrospective study was to evaluate the outcomes of dental implant placement in sinus-augmented areas with preexisting sinus mucosal thickening...

Giant basal cell carcinomas (GBCCs) are large basal cell carcinomas (BCCs; <5 cm) with a greater propensity to invade and metastasize than standard BCCs. The presence of 2 GBCCs in a single individual is rare. We present the case of a 71-year-old Caucasian male with bilateral GBCCs on the dorsal forearms, measuring 130 cm(2) and 24 cm(2), respectively, that developed over a 21-year period. Over this period, the patient treated the tumors with herbal remedies. Histologic evaluation showed a conventional nodular BCC for both tumors...

BACKGROUND: The rise of antimicrobial use in the twentieth century has significantly reduced morbidity due to infection, however it has also brought with it the rise of increasing resistance. Some patients are on prolonged, if not "life-long" course of antibiotics. The reasons for this are varied, and include non-infectious indications. We aimed to study the characteristics of this potential source of antibiotic resistance, by exploring the antibiotic dispensing practices and describing the population of patients on long-term antibiotic therapy...

The large volume of adult living donor liver transplantations (ALDLTs) at our center affords a unique opportunity to examine the impact of acute-on-chronic liver failure (ACLF) among high-MELD score patients. From February 1998 to March 2010, 1958 cirrhotic recipients were analyzed to study the relationship between MELD scores and ALDLT outcomes. A total of 327 high-MELD score recipients were categorized into ACLF and non-ACLF groups, and their outcomes were compared. The five-year graft and patient survival in the high MELD group were 75...

Arrays of probe molecules integrated into a microfluidic cell are utilized as analytical tools to screen the binding interactions of the displayed probes against a target molecule. These assay platforms are useful in enzyme or antibody discovery, clinical diagnostics, and biosensing, as their ultraminiaturized design allows for high sensitivity and reduced consumption of reagents and target. We study here a platform in which the probes are first grafted to microbeads which are then arrayed in the microfluidic cell by capture in a trapping course...

Regeneration and establishment of osseointegration within oral peri-implant bone defects remains a clinical challenge. Bone tissue engineering (BTE) is emerging as a promising alternative to autogenous and/or biomaterial-based bone grafting. The objective of this systematic review was to answer the focused question: in animal models, do cell-based BTE strategies enhance bone regeneration and/or implant osseointegration in experimental peri-implant defects, compared to grafting with autogenous bone or only biomaterial scaffolds? Electronic databases were searched for controlled animal studies reporting on peri-implant defects and implantation of mesenchymal stem cells (MSC) or other cells seeded on biomaterial scaffolds, following PRISMA guidelines...

Genetic organization is governed by the interaction of DNA with histone proteins, and differential modifications of these proteins is a fundamental mechanism of gene regulation. Histone modifications are primarily studied through chromatin immunoprecipitation (ChIP) assays, however conventional ChIP procedures are time consuming, laborious and require a large number of cells. Here we report for the first time the development of ChIP in droplets based on a microfluidic platform combining nanoliter droplets, magnetic beads (MB) and magnetic tweezers (MT)...
