The tissue distribution and some properties of human alpha-mannosidase (alpha-D-mannoside mannohydrolase EC 3.2.1.24) have been studied. The acidic forms of the enzyme were fairly stable, whereas the neutral forms easily lost enzymic activity. The acidic forms were sensitive to neuraminidase but the neutral forms were unaffected. The experiments indicate that the acidic components are closely rela

Aims: This study investigates the risk of small for gestational age (SGA) in relation to country of origin of the mother. The role of psychosocial resources, socioeconomic and lifestyle factors was examined in different causal models. Methods: Among all pregnant nulliparous women in the city of Malmo¨ , Sweden, who gave birth in 1991 – 92, 872 (87.7%) women completed a questionnaire during their f

Aim: To study collagen-induced arthritis in human leucocyte antigen (HLA)-DR1 transgenic mice lacking endogenous major histocompatibility complex class II molecules (MHC-II) and to determine T cell specificity against the arthritogenic CII259-273 epitope of type II collagen either unmodified or post-translationally glycosylated at Lys(264). Methods: Arthritis was induced by immunisation with human

3,4-Dihydroxyphenyl-(L)-alanine ((L)-DOPA)-induced dyskinesia is associated with molecular and synaptic plasticity in the basal ganglia, but the occurrence of structural remodeling through cell genesis has not been explored. In this study, rats with 6-hydroxydopamine lesions received injections of the thymidine analog 5-bromo-2'-deoxyuridine (BrdU) concomitantly with (L)-DOPA for 2 weeks. A large

The CELLION project is directed towards the studies on cellular response to targeted single ions. This paper gives an account of the modifications made at the Lund sub-micron beam line in order to create a Single Ion Hit Facility for biological applications within the CELLION project. The most relevant new feature is the specially developed software used to locate the cells. A program for cell rec

We present a scheme for generating multiple, strongly interacting qubits in rare-earth-ion-doped inorganic crystals at cryogenic temperatures. Two ground state hyperfine levels, with hour long lifetimes and ms decoherence times are chosen as qubit states. Controlled logic between the qubits is accomplished using the change in permanent dipole moment induced by an optical transition between the gro

Control loops that are closed over a communication network get more and more common. A problem with such systems is that the transfer delays will be varying with different characteristics depending on the network hardware and software. The network delays are typically varying due to varying network load, scheduling policies in the network and the nodes, and due to network failures. Two network mod

Dynamic fracture experiments on crack initiation and crack growth in single edge bend specimens are performed. The impact velocity is in the range of 14 to 50 m/s and the specimen size is 320 x 75 mm with a thickness varying from 18 to 40 mm. The experiments are recorded by high speed photography. Two different steel qualities are investigated and their constitutive characterisation are obtained f

The phase behavior of ternary mixtures containing an alkyltrimethylammonium polyacrylate complex salt, water, and a nonpolar "oil" (n-decanol, p-xylene or cyclohexane) is investigated. The complex salts were prepared with short or long polyacrylates (30 or 6000 repeating units) and with hexadecyltrimethylammonium or dodecyltrimethylammonium surfactant ions. Phase diagrams and structures were deter

The precision of single-shot coherent anti-Stokes Raman spectroscopy (CARS) thermometry is an important characteristic for the application of CARS in various combustion devices such as internal combustion engines. It is generally assumed that the precision of CARS is directly related to the spectral noise of the interacting laser fields, and previous studies have presented a theoretical model desc

Tänk er en stad som ligger i en öken. När det blir riktigt hett kan det bli upp till 45 grader i skuggan. Medeltemperaturen på årsbasis är cirka 22 och som varmast är det i juli och augusti med 33 grader i genomsnitt. Med sådan hetta är det inte förvånansvärt att man förr i tiden dödade varandra för tillgången till vatten. Tänk er att denna stad är den snabbast expanderande staden i landet. Mellan

Structures of concentrated mixtures of associating polymer-surfactant mixtures are important in many technical applications. Yet an in-depth understanding of how molecular parameters affect these structures is lacking. We here summarize the results of ongoing work using a novel simplified approach to the study of associating oppositely charged polymer-surfactant mixtures, introducing a minimum num

Low-lying excited states in the odd-odd N = Z nucleus 62Ga have been investigated following the heavy-ion fusion-evaporation reaction 40Ca(24Mg,pn)62Ga near the Coulomb barrier. Special emphasis is devoted to the search for nonyrast states. The extended decay scheme of 62Ga is compared to spherical shell-model calculations employing the pf5/2g9/2 valence space.

We report the outcome of 71 consecutive posterolateral lumbar fusions without spinal instrumentation. The indication for the operation was spondylolysis-olisthesis, degenerative disc disease/facet joint arthrosis, or pain after prior laminectomy. Concerning pain relief, 29/43 patients with spondylolysis-olisthesis were classified as good. The corresponding figures in the group with degenerative di

The thesis concerns the characterization and evaluation of nonsteady heat transfer in building components and building enclosures. The major aim of the underlaying research has been to assemble and develop simplified calculation procedures for this purpose. To establish a simple model for heat balance calculations three main items are treated: simplification of the heat transfer operators, the des

Aims and objectives. The aim of this study was to describe characteristics in burn injuries in children (zero to six years old), consulting primary care and hospital-based care in Malmo, Sweden. Burn-injured children consulting the University Hospital or the 21 Health Centres, during year 1998 and year 2002, were included. Background. Epidemiological studies of burns in children have mostly been h
