The use of amino acids for the synthesis of novel surfactants with vesicle-forming properties potentially enhances the biocompatibility levels needed for a viable alternative to conventional lipid vesicles. In this work, the formation and characterization of catanionic vesicles by newly synthesized lysine- and serine-derived surfactants have been investigated by means of phase behavior mapping and

Aerodynamic theories of bird flight predict that horizontal flight speed will increase with increasing load whereas vertical Eight speed will decrease. Horizontal flight speed for birds minimizing overall time on migration is predicted to be higher than flight speed for birds minimizing energy expenditure. In this study we compare flight speeds of Brent Geese Branta b. bernicla recorded by trackin

Cellular uptake of several viruses and polybasic macromolecules requires the expression of cell-surface heparan sulfate proteoglycan (HSPG) through as yet ill-defined mechanisms. We unexpectedly found that among several cell-surface binding scFv anti-HS antibody (alphaHS) clones only one, AO4B08, efficiently translocated macromolecular cargo to intracellular vesicles through induction of HSPG endo

We report on the realization of a novel interdigitated cantilever array with electrostatic control of the shape of the interdigitated array. It consists of an array of SiO2/metal double-finger cantilevers in a grating configuration together with an electrical connection part. The complete grating structure is fabricated with nanoimprint lithography, UV lithography and reactive ion etching. The pat

The role of c-Jun activation for survival and regeneration of sensory neurons is unclear. Here we report that c-Jun N-terminal kinase (JNK)-mediated c-Jun activation is important for axonal outgrowth of sensory neurons in rat nodose and dorsal root ganglia (DRG). Peripheral severance of the vagus or the sciatic nerve resulted in a massive and rapid, but transient increase of the activated JNK (p-J

This study aimed to determine the effect of supplementation with conjugated linoleic acids (CLAs) plus n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) on body composition, adiposity, and hormone levels in young and older, lean and obese men. Young (31.4 +/- 3.9 years) lean (BMI, 23.6 +/- 1.5 kg/m(2); n = 13) and obese (BMI, 32.4 +/- 1.9 kg/m(2); n = 12) and older (56.5 +/- 4.6 years) lea

Fermentation of pure teff (Eragrostis teff), pure grass-pea (Lathyrus sativus), and their mixtures, 9:1 and 8:2 (teff/grass-pea) has been done at two temperatures (room temperature and 35 C) in duplicate using the strains of Lactobacillus plantarum, for bacterial fermentation, and Aspergillus oryzae and Rhizopus oligosporus in succession for solid-state fungal fermentation as inocula. In addition,

Abstract in UndeterminedIntestinal epithelial cells (IECs) play a key role in Crohn's disease, a chronic inflammatory bowel disease which requires invasive examinations to be diagnosed. The comparison of the cellular protein expression profiles of Crohn's disease patients and healthy subjects is fundamental for the identification of proteins clinically relevant as new biomarkers or as drug targets

The Euro50 is a telescope for optical and infrared wavelengths. It has an aspherical primary mirror with a size of 50 meters and 618 segments. The optical configuration is of Gregorian type and the secondary mirror is deformable for adaptive optics. Observations can take place in prime focus, Gregorian foci, and Nasmyth foci using additional relay mirrors. The telescope provides seeing limited obs

Background: A recent estimation in a psychiatric cohort showed numbers of noncompliance between 10% and 60%. Therapeutic drug monitoring (TDM) is one method assessing compliance by analysis of drug concentration in the blood. Method: During a 24-week phase IV clinical trial, five repeated serum samples of sertraline (SERT) and N-desmethylsertraline (DSERT), trough values in steady state, were coll

Micromotion of the tibial component in 40 knee arthroplasties for gonarthrosis was studied rising Roentgen stereophotogrammetric analysis. The stability of this component was assessed for 2 years' postoperatively. in all arthroplasties, an attempt was made to reconstruct the preoperative posterior slope. Posterior cruciate-retaining (CR) and posterior-stabilized (PS) components showed at 2 years a

An interference quenching of the nu"=1 vibrational line in the resonant Auger decay of N 1s-->pi(*) core-excited N-2 is observed and analyzed. The intensity ratio between the nu"=1 and nu"=0 vibrational levels of the X(2)Sigma(g)(+) final state shows a surprising nonmonotonous variation as a function of frequency detuning, going through a minimum with a complete suppression of nu"=1. We have devel

Objective: Hyperostosis-hyperphosphataemia syndrome (HHS) is a rare hereditary disorder characterized by hyperphosphataemia, inappropriately normal or elevated 1,25-dihydroxyvitamin D-3 and localized painful cortical hyperostosis. HHS was shown to be caused by inactivating mutations in GALNT3, encoding UDP-N-acetyl-alpha-D-galactosamine: polypeptide N-acetylgalactosaminyltransferase 3 (GalNAc-tran

Seventy-one patients with neuroblastoma (NB) and 25 patients with other neoplastic or nonneoplastic diseases were studied with MIBG scintigraphy. Sensitivity and specificity at diagnosis were 94% and 88%, respectively. Of 52 patients with NB studied during follow-up, 14 had on one or several occasions conflicting results, when the findings at MIBG scintigraphy were compared to standard investigati

In this paper, we demonstrate, for the first time, how an external osmotic gradient can be used to regulate diffusion of solutes across a lipid membrane. We present experimental and theoretical studies of the transport of different solutes across a monoolein membrane in the presence of an external osmotic gradient. The osmotic gradient introduces phase transformations in the membrane, and it cause
