Effect of nonrelativistic interface Hamiltonian on optical transitions in broken-gap heterostructures
Using the Burt-Foreman envelope function theory and an eight-band k.p model, we have extended our previous work [Semenikhin et al. Phys. Rev. B 76, 035335 (2007)] on optical transitions in InAs/GaSb quantum wells grown along the [001] direction by completing the interface Hamiltonian with the inclusion of its nonrelativistic part. We found a substantial contribution of the nonrelativistic term to
Synthesis and self-aggregation of enantiopure and racemic molecular tweezers based on the bicyclo[3.3.1]nonane framework.
A pair of molecular tweezers (syn-4) that consists of quinoline and pyrazine units fused to a bicyclic framework is presented. The tweezers were synthesised both as a racemic mixture (rac-4) and an enantiomerically pure form ((R,R,R,R)-4) starting from either racemic or enantiomerically pure bicyclo[3.3.1]nonane-2,6-dione (3). Homochiral dimers were observed in the solid state for rac-4. The self-

European policy approaches to promote servicizing
Servicizing is a business model that holds the potential to support a shift towards more sustainable production and consumption by selling to the consumer the product's function, rather than the material product itself. This can offer direct environmental benefits by reducing the material and energy intensity of market transactions. Servicizing based business offers are starting emerging on the ma

Association and electrostatic steering of alpha-lactalbumin-lysozyme heterodimers
The salt and pH dependent association of hen egg white lysozyme with alpha-lactalbumin whey proteins has been studied using molecular level Monte Carlo simulations. A highly uneven charge distribution of alpha-lactalbumin leads to strongly ordered heterodimers that may facilitate the formation of structured, mesoscopic aggregates. This electrostatic steering gives rise to 80% alignment at 5 mM 1:1
Comparing aerodynamic efficiency in birds and bats suggests better flight performance in birds.
Flight is one of the energetically most costly activities in the animal kingdom, suggesting that natural selection should work to optimize flight performance. The similar size and flight speed of birds and bats may therefore suggest convergent aerodynamic performance; alternatively, flight performance could be restricted by phylogenetic constraints. We test which of these scenarios fit to two meas
Hydroxyapatite as a novel reversible in situ adsorption matrix for enzyme thermistor-based FIA
The application of the easily available and inexpensive chromatographic matrix hydroxyapatite for reusable and reversible immobilization of enzymes for enzyme thermistor-based flow injection analysis of glucose and Urea was tested. The immobilization was achieved by simple affinity adsorption of glucose oxidase and urease by a suitable pH-induced alteration of the protein charge. A linear detectio
Current Vaccination Strategies for Prostate Cancer
Context: The first therapeutic cancer vaccine demonstrating effectiveness in a phase 3 study was approved by the US Food and Drug Administration on 29 April 2010. The pivotal trial demonstrated overall survival (OS) benefit in patients treated with antigen-loaded leukapheresis cells compared with a control infusion. Results of other prostate cancer (PCa) vaccination strategies are awaited, as this

Documentation of atrial fibrillation prior to first-ever ischemic stroke.
We assessed the prevalence of atrial fibrillation (AF) prior to first-ever ischemic stroke by examining a comprehensive electronic ECG archive.
Growth is dependent on the exocrine pancreas function in young weaners but not in growing-finishing pigs
A correlation between the exocrine pancreatic function and growth has been previously demonstrated in growing pigs but the data are inconsistent. This was investigated by studying the growth performance of pigs with exocrine pancreatic insufficiency (EPI) at different ages and maintained under similar conditions. Twelve 7 week old (10.5 +/- 1.3 kg) weaners, and twelve 16 week old (43 +/- 5 kg) gro
Prevalence of eating difficulties and malnutrition among persons within hospital care and special accommodations
Objectives: The aim of this study was to explore the prevalence of eating difficulties and malnutrition among persons in hospital care and in special accommodations. Design: The cross-sectional observational study was performed in Nov. 2005. Setting: Hospitals and special accommodations. Participants: Out of 2945 persons, 2600 (88%) agreed to participate (1726 from special accommodations and 874 f
Biodistribution and pharmacokinetics of recombinant α1-microglobulin and its potential use in radioprotection of kidneys.
Peptide-receptor radionuclide therapy (PRRT) is a systemically administrated molecular targeted radiation therapy for treatment of neuroendocrine tumors. Fifteen years of clinical use show that renal toxicity, due to glomerular filtration of the peptides followed by local generation of highly reactive free radicals, is the main side-effect that limits the maximum activity that can be administrated
Analytical theory of ideal polydisperse polymers at interfaces
We use a recently developed continuum theory to present an exact treatment of the interfacial properties of ideal polymers displaying Schulz-Flory polydispersity. Our results are remarkably compact and can be derived from the properties of equilibrium, ideal polymers at interfaces. We apply our theory to a number of cases, including, non-adsorbing and adsorbing surfaces, as well as telechelic chai
Efficacy of preoperative radiochemotherapy in patients with locally advanced pancreatic carcinoma
Background. The optimal care for patients with unresectable, non-metastatic pancreatic adenocarcinoma (PAC) is debated. We treated 17 consecutive cases with preoperative radiochemotherapy (RCT) as a means for downstaging their tumours and compared outcome with 35 patients undergoing direct surgery for primarily resectable PAC during the same time period. Methods. The patients had biopsy proven, un
Binding of complement regulators to invasive nontypeable Haemophilus influenzae is not increased compared to nasopharyngeal isolates, but serum resistance is linked to disease severity.
The aim of the present study was to analyse the importance for non-typeable Haemophilus influenzae (NTHi) isolated from patients with sepsis (invasive isolates) compared to nasopharyngeal isolates from patients with upper respiratory tract infection to resist the complement-mediated attack in human serum and to correlate this to disease severity. We in detail studied and characterized cases of inv
