Arrays of silicon nanowires (Si NW) may be used in the development of implantable drug delivery systems. Here, we performed short-and long-term cultures of mouse retinal cells on substrates consisting of high aspect ratio Si NW, which confers high porosity to the surface. As controls, cells were grown on flat silicon substrates. The cell phenotype was assessed using immunocytochemistry, fluorescen

This publication describes the methods used to measure the centrality of inelastic Pb-Pb collisions at a center-of-mass energy of 2.76 TeV per colliding nucleon pair with ALICE. The centrality is a key parameter in the study of the properties of QCD matter at extreme temperature and energy density, because it is directly related to the initial overlap region of the colliding nuclei. Geometrical pr

Background: The Southern Swedish Malignant Melanoma (SSMM) research team is a truly cross functional group with members from oncology, clinical, surgery, bioinformatics, proteomics, and genomics initiatives. The SSMM’s objectives and goals are to develop, build and utilize cutting edge biobanks and OMICS platforms to better understand disease pathology and drug mechanisms. Within the research team

Activated sludge model (ASM) is now widely used for wastewater treatment plant design, optimization and operation. Values for parameters to be used are vital for the accuracy of the modeling approach. This study aims to establish the scientific link between typical treatment and biodegradability of different chemical oxygen demand (COD) fractionation of palm oil mill effluent (POME), by means of r

Magnetic properties of particles are generally determined from randomly oriented ensembles and the influence of the particle orientation on the magnetic response is neglected. Here, we report on the magnetic characterization of anisotropic spindle-type hematite particles. The easy axis of magnetization is within the basal plane of hematite, which is oriented perpendicular to the spindle axis. Two

All aerobic organisms are to some degree affected by oxidative stress, which is an imbalance between pro-oxidants and antioxidants in favor of the former. Pro-oxidants can damage DNA, proteins and lipids, and as such oxidative stress can carry considerably fitness costs. In mammals excessive calorie intake is a known cause of oxidative stress. We investigated whether in migrant birds, which typica

Addition of surfactants to aqueous solutions of polyelectrolytes carrying an opposite charge causes the spontaneous formation of complexes in the bulk phase in certain concentration ranges. Under some conditions, compact monodisperse multichain complexes are obtained in the bulk. The size of these complexes depends on the mixing procedure and it can be varied in a controlled way from nanometers up

We prove that in linear periodic gravity water waves there are no closed orbits for the water particles in the fluid. Each particle experiences per period a backward-forward motion that leads overall to a forward drift.

The residual stresses generated during D-Gun spraying process act as pre-existing stresses and seriously affect the various types of coating performance. To produce a reliable coating, it is necessary to know the influence of residual stress on the adhesive behavior of coating/substrate system. Based on the residual stress formula for thick coatings and accurate curvature measurements, the residua

We study the dynamic admission control for a finite shared buffer with support of multiclass traffic under Markovian assumptions. The problem is often referred to as buffer sharing in the literature. From the linear programming (LP) formulation of the continuous-time Markov decision process (MDP), we construct a hierarchy of increasingly stronger LP relaxations where the hierarchy levels equal the

SUMMARY: The bacterial ω-transaminase from Chromobacterium violaceum (Cv-ωTA, EC 2.6.1.18) catalyzes industrially important transamination reactions by use of the coenzyme pyridoxal 5'-phosphate (PLP). Here, we present four crystal structures of Cv-ωTA: two in the apo form, one in the holo form and one in an intermediate state, at resolutions between 1.35 and 2.4 Å. The enzyme is a homodimer with

Background. Male breast cancer (MBC) is an uncommon disease and there is limited information on the prognostic impact of routinely used clinicopathological parameters. Material and methods. In a retrospective setting, we reviewed 197 MBC patients with accessible paraffin-embedded tumor tissue and clinicopathological data. Immunohistochemical (IHC) stainings were performed on tissue microarrays and

Based on simultaneous analysis of the frequency-resolved transient grating, peak shift, and echo width signals, we present a model for the third-order optical response of carotenoids including population dynamics and system-bath interactions. Our frequency-resolved photon echo experiments show that the model needs to incorporate the excited-state absorption from both the S-2 and the S-1 states. We

Self-inflicted aggressive behaviour is a cross diagnostic phenomenon of major clinical relevance in psychiatric setting. Accumulating evidence speaks for a role of metabolic and immunological factors in aggressive behaviour. The aim of this thesis is to enlighten the role of leptin, insulin, glucagon, glucose and IL-1beta in the context of self-inflicted aggressive behaviour. We used cerebrospinal
