Populations previously included in Xanthoparmelia lineola and X. digitiformis from Australia and North America have been investigated using ITS rDNA sequences, chemistry and morphology and have been compared with possible related species. The new species, Xanthoparmelia knudsenii Elix, A. Thell & Søchting is described and the new combination Xanthoparmelia rimalis (Kurok.) Elix, A. Thell &

Iron-mediated synthesis of alkali metal iodides was quite unexpectedly demonstrated to be able to serve as a cost-efficient and reliable source of spherical single crystalline near-stoichiometric magnetite (Fe3O4) nanoparticles as revealed by TEM and XRD studies and also by XANES spectroscopic quantification of the Fe2+-content. Using the particles as nuclei for the Stoeber synthesis of silica nan

Background: Gaucher disease (GD) is the most common inherited lysosomal storage disorder in humans, caused by mutations in the gene encoding the lysosomal enzyme glucocerebrosidase (GBA1). GD is clinically heterogeneous and although the type of GBA1 mutation plays a role in determining the type of GD, it does not explain the clinical variability seen among patients. Cumulative evidence from recent

Popular Abstract in Swedish Vårt blod består av flera olika specialiserade typer av celler. Dessa utför allt från transport av syre (röda blodkroppar) och sårläkning (blodplättar) till att utgöra vårt immunsystem (vita blodkroppar). Vårt immunförsvar kommer ständigt i kontakt med virus, bakterier och sjuka celler som måste kännas igen och bekämpas. Därför finns det ett kontinuerligt behov av att bB-cells are an essential part of our adaptive immune system. A network of transcription factors together with external signals facilitate the gradual developmental progression from progenitor cells towards the B-cell fate. Several key factors participating in this network have been identified. Among these are the transcription factors E2A, HEB, EBF1 and FOXO1 as well as the IL7 signaling cascade.

Malaria is a major global cause of deaths and a vaccine is urgently needed.

We analyse the first-passage properties of two random walkers confined to a finite one-dimensional domain. For the case of absorbing boundaries at the endpoints of the interval, we derive the probability that the two particles meet before either one of them becomes absorbed at one of the boundaries. For the case of reflecting boundaries, we obtain the mean first encounter time of the two particles

BACKGROUND: Low nuclear expression of the RNA-binding motif protein 3 (RBM3) has previously been found to be associated with poor prognosis in several cancer forms e.g. breast, ovarian, colorectal, prostate cancer and malignant melanoma. The aim of this study was to examine the prognostic impact of RBM3 expression in urinary bladder cancer.METHODS: Immunohistochemical RBM3 expression was examined

A variety of palaeoclimatic records show a shift towards cooler, wetter and windier conditions in Europe around 2800 cal a BP. The shift broadly coincides with an increase of the atmospheric C-14 concentration, suggesting a connection between solar activity variations and climate change. Here we investigate a peat record from Undarsmosse in southern Sweden. In a previous study, based on a low-reso

A monographic book volume on the history of the rural landscape of Europe is presented (Emanuelsson, The rural landscape of Europe. How man has shaped European nature, 383, 2009). The focus is on various land-use phases, their history from the Neolithic period to modern time and the survival of traditional farming today in Europe. This is described and illustrated by examples from marginal farming

The volume presents the results of an international project carried out in cooperation between the Uppsala University, the Hebrew University in Jerusalem, Lund University and the University of Gothenburg. The questions put forward in the project were: How is hypotaxis marked in Semitic, other than by conjunctions? How does this affect the organization of texts? More specifically, what constitutes

One of the major problems in contemporary Swedish society is an increasing proportion of psychologically ailing young people. It is often argued that one of the reasons for this situation is declining possibilities for young people to actively participate and engage in Swedish society. One important area of participation and involvement for young people could be religious organizations. Thus, the

This note is based on a literature search and a recent review of bat mortality data from wind farms in Europe (published elsewhere). We suggest that mortality of bats at wind turbines may be linked to high-altitude feeding on migrating insects that accumulate at the turbine towers. Modern wind turbines seem to reach high enough into the airspace to interfere with the migratory movements of insects

Background: Despite the fact that HIV-positive women carry an increased risk of developing cervical cancer (CC) in comparison with HIV-negative women, HIV and CC screening programs in many developing countries have remained unintegrated. The objective of this study is to explore perceptions and preferences of community members in Uganda, including women, men, and village health teams, regarding th

Objectives To determine the detection rate of fetal malformations and chromosomal abnormalities and the rate of false-positive ultrasound diagnoses at routine ultrasound examinations carried out by specially trained midwives in an unselected pregnant population front 2000 to 2005, and to describe the consequences of true-positive and false-positive ultrasound diagnoses of fetal malformations.
