Glycobiology is the world of sugars: how they are made, what they look like, and what they do. Despite the importance of glycan structures in life, knowledge has been hampered due to their inherent complexity. Lectins are nature's way to decipher the intricate code held by glycans, which makes them important players in both normal and pathological physiology. A key to the understanding of lectins
We present a parameter-free model that estimates the density of excitons in Cu2O, related to experiments that have tried to create an excitonic Bose-Einstein condensate. Our study demonstrates that the triplet-state excitons move along adiabats and obey classical statistics, while the singlet-state excitons are a possible candidate for forming a Bose-Einstein condensate. Finally we show that the r
BACKGROUND: Acute pancreatitis (AP) results in elevated concentrations of trypsinogen (T) isoenzymes in serum. Immunoreactive anionic trypsinogen in urin (irAT/u) is elevated in AP, and has recently been proposed as a rapid diagnostic instrument and severity predictor. These results have not been confirmed by other groups, and irAT/u has not been further characterized. The concentration of immun
A known problem of the HCCI engine is its lack of direct control andits requirements of feedback control. Today there exists severaldifferent means to control an HCCI engine, such as dual fuels,variable valve actuation, inlet temperature and compression ratio.Independent of actuation method a sensor is needed. In this paper weperform closed-loop control based on two different sensors, pressureand
A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for non-small cell lung cancer (NSCLC) is based on data from 4 meta-analys
We present evidence for ultra-fast dissociation of molecular ammonia when photo-excited to the Nls --> 4a(1) core-hole state. This finding is based on resonant Auger spectroscopical results as well as qualitative arguments concerning the photon energy dependence of the Auger structures. Calculations of the excited state potential based on the Z + l approximation were performed. Both the calculatio
Background. Plasma markers for intestinal ischemia have not proven to be accurate. The value of L-lactate is unclear. Experimental models based on open surgery confound the effects of surgical trauma with that of ischemia. The aim was to create an endovascular model for acute superior mesenteric artery thromboembolism, and then to study L-lactate and lactate dehydrogenase (LD) activity in plasma a
Question: How can we link genotypic, phenotypic, individual, population, and community levels of organization so as to illuminate general ecological and evolutionary processes and provide a framework for a quantitative, integrative evolutionary biology? Framework: We introduce an evolutionary framework that maps different levels of biological diversity onto one another. We provide (1) an overview
The first evidence for excited states in In-101 is presented. In-101 is the lightest In isotope observed in an in-beam experiment. Two gamma-ray transitions at 1309 and 341 keV, respectively, are strong candidates for a cascade to the ground state in this nucleus. In shell-model terms it has one proton hole and two neutron particles outside the double shell closure at Sn-100. New ideas for improvi
The Trianon treaty has been a prominent site of memory in Hungarian historical culture from the day it was undersigned on 4 June 1920. 564,000 Hungarian Jews became victims of the Holocaust. In the first years after the end of World War II, the Holocaust was not a concept in Hungarian politics and historical culture. In the interwar period, in Hungarian historical culture the Trianon syndrome exhi
Background: Low adherence is a key factor in explaining impaired effectiveness and efficiency in the pharmacological treatment of hypertension. However, little is known about which factors determine low adherence in actual practice. The purpose of this study is to examine whether low social participation is associated with low adherence with antihypertensive medication, and if this association is
Persistent organic pollutants such as polychlorinated biphenyls (PCBs) and the pesticide DDT, known to harm wildlife, have been shown to reach pristine Subarctic and Arctic areas by global atmospheric transport. Another transport route for pollutant entry into these ecosystems is provided by migrating salmon. Pollutant transport was studied in a population of sockeye salmon (Oncorhynchus nerka) in
There are few investigations of the type and the outcome of interventions aimed at supporting nurses caring for psychiatric patients. Therefore a prepost-test design study was used in which 22 psychiatric nurses, on a general psychiatric ward were examined before, during and after one year of systematic clinical supervision combined with supervised documented, planned, individualized care. The met
