A Feudal Way to Gentrify? The current understanding of gentrification and changes of social-topography in a medieval and early modern town
Gentrification is a current and often debated concept that concerns social changes in our cities. The concept relates to a development whereby areas earlier inhabited by less wealthy social groups are taken over by middle and upper middle-class residents. In the discussions of these changes, two perspectives have dominated. Representatives for the consumer perspective argue that gentrification occ
The influence of initial pressurization and cup introduction time on the depth of cement penetration in an acetabular model.
Background Acetabular cementation during total hip arthroplasty is considered difficult mainly due to the appearance and anatomy of the acetabulum. Improved cementation technique has been shown to improve the longevity of acetabular components. Method We designed a ceramic model to investigate the effect of varying the initial cement pressurization and cup introduction times on the depth of cemen
Islet constitutive nitric oxide synthase: biochemical determination and regulatory function
Recent immunohistochemical findings suggested that a constitutive nitric oxide synthase (cNOS) resides in endocrine pancreas. Here we provide direct biochemical evidence for the presence of cNOS activity in isolated islets. The regulating influence of this nitric oxide synthase (NOS) activity for islet hormone release was also investigated. We observed that cNOS activity could be quantitated in is
Colour development in copper ruby alkali silicate glasses. Part 1. The impact of tin(II) oxide, time and temperature
The development of the red colour in copper ruby alkali silicate glasses has been studied by means of ultraviolet/visible spectroscopy, TEM and EXAFS. The results show that in both red and slightly overstruck, brownish glasses the colour is due to clusters of metallic copper. Before striking non-coloured glasses contain mainly cuprous ions, Cu+. Tin acts as a reducing agent but also has an acceler

alpha-Trinositol inhibits FGF-stimulated growth of smooth muscle and breast cancer cells
alpha-Trinositol (D-myo-inositol-1,2,6-trisphosphate), an isomer of the intracellular messenger IP3, has been studied for its anti-inflammatory and other effects in animal experiments and in human. The mechanisms of action remain unknown. Several human pathologies are associated with uncontrolled production of fibroblast growth factors (FGFs). FGF-2 induces vascular smooth muscle cell proliferatio
Development and testing of a frequency-agile optical parametric oscillator system for differential absorption lidar
An all-solid-state fast-tuning lidar transmitter for range- and temporally resolved atmospheric gas concentration measurements has been developed and thoroughly tested. The instrument is based on a commercial optical parametric oscillator (OPO) laser system, which has been redesigned with piezoelectric transducers mounted on the wavelength-tuning mirror and on the crystal angle tuning element in t
Wind-dependent foraging flight in the Osprey Pandion haliaetus
We studied the foraging technique of Ospreys Pandion haliaetus during different wind speed conditions at Lake Hammarsjon, Sweden in autumn 2003. Different fishing techniques were used with a shift in relation to wind speed: (1) without hovering, (2) hovering with pure flapping flight, (3) hovering with flapping flight and gliding into the wind, and (4) hovering with pure gliding. The results suppo
MRSA in children from foreign countries adopted to Swedish families
Aim: To determine if children adopted to Swedish families from countries with a high carrier rate of methicillin-resistant Staphylococcus aureus (MRSA) are infected or colonized with MRSA. Methods: From January 2000 to May 2005, 23 adopted children from 6 countries were examined for MRSA at the University hospital in Lund after their arrival in Sweden. Results: Thirteen of the 23 children (57%) we

A hint at quark deconfinement in 200 GeVAu+Au data at RHIC
We give the emission function of the axially symmetric Buda-Lund hydro, model and present its simultaneous, high quality fits to identified particle spectra, two-particle Bose-Einstein or HBT correlations and charged particle pseudorapidity distributions as measured by BRAHMS and PHENIX in 0-30% central, roots(NN) = 200 GeV Au+Au collisions at RHIC. The best fit is achieved when the most central r

Determination of allotypes G1m(f) and G1m(z) at the genomic level by subclass specific amplification of DNA and use of allele specific probes
Two oligonucleotide primers were used for selective enzymatic amplification of a DNA segment encoding a major portion of the first constant region domain (CH1) of the human IgG1 heavy chain. The selective amplification was confirmed by use of subclass-specific oligonucleotide probes. Two 15-mer oligonucleotides, hybridizing with the alleles for the allotypes G1m(f) and (z), respectively, could the

Interactions between streptococcal M proteins and human plasma proteins
Popular Abstract in Swedish Streptokocker orsakar flera olika infektioner hos människa såsom halsfluss, svinkoppor och sällsynta livshotande sjukdomstillstånd som blodförgiftning, toxiskt chock syndrom, nekrotiserande fasciit, glomerulonefrit, och reumatisk feber. För att orsaka dessa infektioner måste bakterierna undvika immun-försvaret. Komplementsystemet utgör en viktig del av det medfödda immuStreptococcus pyogenes is a common human pathogen, which causes a variety of diseases. A major virulence factor of S. pyogenes is the surface-associated M protein, which mediates resistance to phagocytosis. Several studies indicate that M proteins inhibit complement deposition and thereby phagocytosis. It is often assumed that S. pyogenes lacking M protein activates complement via the alternative
The influence of plasma insulin concentrations on tissue insulin levels in rodents: a study of the diabetic Chinese hamster and the ob/ob mouse
Immunoreactive insulin was measured in acid-ethanol extracts of kidney, brain, liver, and heart from genetically diabetic Chinese hamsters and their nondiabetic controls and from obese (ob/ob) mice and their thin littermates. Selected samples were filtered on Sephadex G-50 columns and the insulin concentration determined. There was a good correlation between the insulin level measured in the acid-
