Objectives: To evaluate the transition process from conventional carotid endarterectomy (cCEA) to eversion carotid endarterectomy (eCEA). Methods: Patients operated with carotid endarterectomy (CEA; 164 patients, 171 CEA) in 2002-2003 were retrospectively included. Results: In 2002, cCEA was applied in 64 (80%) and eCEA in 16 (20%) patients. There was an inversion on the preponderant surgical tech

To evaluate the incidence and possible predictors associated with port-site metastases following robotic surgery.

Neutrophil extracellular traps (NETs) have been visualized at the site of ANCA-associated vasculitis (AAV) lesions. Increased levels of NET remnants in the circulation have been reported in some AAV patients with active disease. The aim of the present study was to analyse NET remnants in a larger cohort of AAV patients with varying degrees of disease activity and to elucidate possible factors resp

Introduction - Antioxidants are known to avert oxidation processes and they are found in trees and other plant materials. Tree bark is a major waste product from paper pulp industries; hence it is worthwhile to develop an extraction technique to extract the antioxidants. Objective - To develop a fast and environmentally sustainable extraction technique for the extraction of antioxidants from bark

The number of cancer patients living with metastatic disease is growing. The increased survival has led to an increase in the number of cancer-induced complications, such as pathologic fractures due to bone metastases. Surgery is most commonly needed for mechanical complications, such as fractures and intractable pain. We determined survival, disease free interval and complications in surgically t

Background: Alpha-1 antitrypsin (A1AT) is a protease inhibitor that protects the tissues from degradation by neutrophil elastase under certain pathological process. Alpha-1 antitrypsin deficiency (A1ATD) could associate with both lung and liver pathogenicities. Of all the deficiency alleles, Z mutant is the most common variant and causes severe complications. Here, we described a novel and quick m

Objective: To describe the characteristics of activity bursts in the early preterm EEG, to assess inter-rater agreement of burst detection by visual inspection, and to determine the performance of an automated burst detector that uses non-linear energy operator (NLEO). Methods: EEG recordings from extremely preterm (n = 12) and very preterm (n = 6) infants were analysed. Three neurophysiologists i

The purpose of this study was to assess if the presence of information including the pretest probability (Wells score), other known risk factors, and symptoms given on referrals for computed tomography (CT) pulmonary angiography correlated with prevalence rates for pulmonary embolism (PE). Also, to evaluate for differences between a university and a regional hospital setting regarding patient char

In this study we derive a single-particle equation of motion, from first principles, starting out with a microscopic description of a tracer particle in a one-dimensional many-particle system with a general two-body interaction potential. Using a harmonization technique, we show that the resulting dynamical equation belongs to the class of fractional Langevin equations, a stochastic framework whic

In situ synchrotron powder X-ray diffraction (PXRD) measurements have been conducted to follow the nucleation and growth of crystalline CexZr1-xO2 nanoparticles synthesized in supercritical water with a full substitution variation (x = 0, 0.2, 0.5, 0.8, and 1.0). Direction-dependent growth curves are determined and described using reaction kinetic models. A disctinct change in growth kinetics is o

Chondroadherin (CHAD), a class IV small leucine rich proteoglycan/protein (SLRP), was hypothesized to play important roles in regulating chondrocyte signaling and cartilage homeostasis. However, its roles in cartilage development and function are not well understood, and no major osteoarthritis-like phenotype was found in the murine model with CHAD genetically deleted (CHAD(-/-)). In this study, w

The Idefjorden Terrane of the Sveconorwegian Orogen, Fennoscandia, is known to be an area of comparatively juvenile Mesoproterozoic continental growth. Here we provide an improved model of crustal growth based on new coupled zircon U-Pb-O-Lu-Hf isotopic data on thirteen samples of mafic to intermediate plutonic rocks from different domains of the Idefjorden Terrane. The new data support a retreati

Ensuring occupants' safety in building fires is one of the most important aspects for fire safety engineering. Many uncertainties are inevitably introduced when estimating the occupant safety level, due to the high complexity of fire dynamics and the human behaviour in fires. Safety factor methods are traditionally employed to deal with such uncertainties. This kind of methods is easy to apply but

We report a study of final states containing a W boson and hadronic jets, produced in proton-proton collisions at a center-of-mass energy of 7 TeV. The data were collected with the ATLAS detector at the CERN LHC and comprise the full 2010 data sample of 36 pb(-1). Cross sections are determined using both the electron and muon decay modes of the W boson and are presented as a function of inclusive

Incidence rates of differentiated thyroid carcinoma (TC) have increased in many countries. Adiposity and dietary risk factors may play a role, but little is known on the influence of energy intake and macronutrient composition. The aim of this study is to investigate associations between TC and the intake of energy, macronutrients, glycemic index (GI) and glycemic load in the European Prospective

Key points Hematopoietic stem cell aging associate with stable transcriptional alterations that persist through transplantation.Somatic cell reprogramming of aged hematopoietic stem and progenitor cells reverses functional defects associated with hematopoietic aging.

Transplantation of hematopoietic stem cells (HSCs) to treat hematological disorders is routinely used in the clinic. However, HSC therapy is hindered by the requirement of finding HLA-matched donors, as well as attaining sufficient numbers of long-term HSCs in the graft. Therefore, ex vivo expansion of transplantable HSC remains one of the "holy grails" of hematology. Without the ability to mainta

SWENOTECA has since 1998 offered patients with clinical stage I (CS I) nonseminoma, adjuvant chemotherapy with one course of bleomycin, etoposide and cisplatin (BEP). The aim has been to reduce the risk of relapse, sparing patients the need of toxic salvage treatment. Initial results on 312 patients treated with one course of adjuvant BEP, with a median follow-up of 4.5 years, have been previously

The glycoprotein osteopontin plays important roles in several states of disease associated with inflammation, for example by recruiting neutrophils but its expression and possible roles in cystic fibrosis (CF) have not been investigated.
