Extraction of Antioxidants from Spruce (Picea abies) Bark using Eco-friendly Solvents

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

Insight opinion to surgically treated metastatic bone disease: Scandinavian Sarcoma Group Skeletal Metastasis Registry report of 1195 operated skeletal metastasis

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

A novel method of detecting alpha-1 antitrypsin deficiency of Z mutant (GAG(342)AAG) in a single PCR reaction using base-quenched probe

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

Detection of 'EEG bursts' in the early preterm EEG: Visual vs. automated detection

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

Associations between Presence of Relevant Information in Referrals to Radiology and Prevalence Rates in Patients with Suspected Pulmonary Embolism.

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

Foundation of fractional Langevin equation: Harmonization of a many-body problem

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 Radiation Study of Formation and Growth of Crystalline CexZr1-xO2 Nanoparticles Synthesized in Supercritical Water

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

Nanomechanical phenotype of chondroadherin-null murine articular cartilage.

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

Mesoproterozoic continental growth: U-Pb-Hf-O zircon record in the Idefjorden Terrane, Sveconorwegian Orogen

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

A method for linking safety factor to the target probability of failure in fire safety engineering

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

Study of jets produced in association with a W boson in pp collisions at root s=7 TeV with the ATLAS detector

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

Energy and macronutrient intake and risk of differentiated thyroid carcinoma in the European Prospective Investigation into Cancer and Nutrition (EPIC) study.

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

Two new routes to make blood: Hematopoietic specification from pluripotent cell lines vs. reprogramming of somatic cells.

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

One Course of Adjuvant BEP in Clinical Stage I Nonseminoma Mature and Expanded Results from the SWENOTECA group.

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

Rapid bond rearrangement in molecules after core-electron excitation

Experimental studies of core-excited molecules using three-dimensional multi particle momentum imaging are presented where bond rearrangement processes in dication species are analysed. The aim of the study is to understand the relation between the geometric changes associated with core-excited states and the kinetic energy released in particular molecular dissociation processes. The kinematics of

Escaping peril: perceived predation risk affects migratory propensity.

Although migratory plasticity is increasingly documented, the ecological drivers of plasticity are not well understood. Predation risk can influence migratory dynamics, but whether seasonal migrants can adjust their migratory behaviour according to perceived risk is unknown. We used electronic tags to record the migration of individual roach (Rutilus rutilus), a partially migratory fish, in the wi

The role of the transient receptor potential (TRP) superfamily of cation-selective channels in the management of the overactive bladder

center dot The transient receptor potential (TRP) channel superfamily has been shown to be involved in nociception and mechanosensory transduction in various organ systems, and studies of the LUT have indicated that several TRP channels, including TRPV1, TRPV2, TRPV4, TRPM8, and TRPA1, are expressed in the bladder, and may act as sensors of stretch and/or chemical irritation. center dot However, t
