The 8p11 myeloproliferative syndrome (EMS) is a chronic myeloproliferative disorder molecularly characterized by fusion of various 5' partner genes to the 3' part of the fibroblast growth factor receptor 1 (FGFR1) gene at 8p, resulting in constitutive activation of the tyrosine kinase activity contained within FGFR1. EMS is associated with a high risk of transformation to acute myeloid leukemia (A
In the present study, we investigated if the previously observed JNK-mediated activation of c-Jun and induction of ATF3 could be ascribed to axonal transport of JNK signaling components, or if axonal transport of the transcription factors themselves contributes to the nuclear changes in injured sensory neurons. We observed retrograde axonal transport of a number of JNK upstream kinases in ligated
Pulsed field gradient NMR spectroscopy was used to determine the poly(ethylene glycol) (PEG) self-diffusion coefficient (D-PEG) as a function of NaCl concentration (C-NaCl) and denaturation time (t(D)) in whey protein solutions and gels. D-PEG in the gel decreased with increasing C-NaCl concentrations and increased with increasing t(D); the increase ceased for all PEGs when the gel was fixed. This
The system that regulates insulin secretion from beta-cells in the islet of Langerhans has a capsaicin-sensitive inhibitory component. As calcitonin gene-related peptide (CGRP)-expressing primary sensory fibers innervate the islets, and a major proportion of the CGRP-containing primary sensory neurons is sensitive to capsaicin, the islet-innervating sensory fibers may represent the capsaicin-sensi
A diverse conodont collection representing the Oelandodus elongatus-Acodus deltatus deltatus Subzone of the Paroistodus proteus Zone has been retrieved from a sample from the E bed at Holsbrotten on the west side of Mt. Hunneberg. This bed marks the base of the Tetragraptus approximatus Zone at the nearby Diabasbrottet section, the recently ratified stratotype for the base of the Second Global Sta
Streptomyces coelicolor A3(2) undergoes at least two kinds of cell division: vegetative septation leading to cross-walls in the substrate mycelium; and developmentally regulated sporulation septation in aerial hyphae. By isolation and characterization of a non-sporulating ftsZ mutant, we demonstrate a difference between the two types of septation. The ftsZ17(Spo) allele gave rise to a classical wh
The biliary tract is normally sterile, but bile-tolerant bacteria are frequently isolated from patients with cholecystitis. Since the identification of about 25 Helicobacter species, some of which may grow in bile, studies have addressed the role of these organisms in primary biliary cirrhosis, primary sclerosing cholangitis, and cholelithiasis. Most of these bacteria show the presence of Helicoba
A method is described for measurement of freely dissolved copper concentrations in natural water samples using supported liquid membrane (SLM) extraction under equilibrium conditions, a technique denoted "equilibrium sampling through membranes" (ESTM). For this purpose, 1,10-dibenzyl-1,10-diaza-18-crown-6 as neutral carrier and oleic acid were used in the membrane phase. The main variables optimis
In this paper, we present Vendian palaeomagnetic data for continent Baltica, based on results from the 608 +/- 1 Ma old Sarek Dyke Swarm in northern Sweden. The dykes sit in the Sarektjahkka Nappe of the Seve Nappes, which were thrust eastwards over the Baltic craton during the early Palaeozoic Caledonian Orogeny. In spite of long transport distances as well as deformation and metamorphism in the
The emerging genomic technologies and bioinformatics provide novel opportunities for studying life-threatening human pathogens and to develop new applications for the improvement of human and animal health and the prevention, treatment, and diagnosis of infections. Based on the ecology and population biology of pathogens and related organisms and their connection to epidemiology, more accurate typ
The Homogeneous charge compression ignition (HCCI) principle holds promise to increase efficiency and to reduce emissions from internal combustion engines. As HCCI combustion lacks direct ignition timing control and auto-ignition depends on the operating condition, control of auto-ignition is necessary. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, a fast
The rarefaction technique applied to fossil pollen sequences for analyzing palynological richness, interpreted as a signal of biological diversity of landscapes and vegetation, has been developed since 1988. Errors including population evenness and vegetation disturbance have been considered in this study. Information from two sites is discussed, one with a pollen diagram covering Late-Glacial (La
Expression of C-terminal flanking peptide of neuropeptide Y (CPON) in DRG and cell proliferation (incorporation of BrdU) in sciatic nerve of rats following chronic nerve compression (silicone tubes with different internal diameters) was studied by immunocytochemistry. An increased number of CPON-positive neurons and cells incorporating BrdU was induced on the compressed side, most pronounced when
The aim of the present study is to investigate the relationship between language comprehension and language production in Swedish children. This was done longitudinally with 10 children with specific language impairment (SLI), aged 4;0 to 6;3 at Time I, and 10 children with unimpaired language development, aged 3;1 to 3;7 at Time I. The target structure was subordination, more precisely relative c
