The large-scale geomorphology of the Huang He (Yellow River) headwaters, centered around the Bayan Har Shan (5267 m asl) in the northeastern part of the Tibetan Plateau, is dominated by an uplifted remnant of a low-refief relict plateau with several mountain ranges. We have performed geomorphological mapping using SRTM topographic data and Landsat 7 ETM+ satellite imagery to evaluate landscape cha

An application of a flexible polyvinylimidazole osmium functionalised polymer for efficient electrical wiring of whole Gluconobacter oxydans cells is described. The performance of the redox polymer as a mediator for intact bacterial cells was tested with glucose, ethanol and glycerol, typical substrates of the periplasmically localised PQQ-dependent membrane bound dehydrogenases. The efficiency of

The extracellular matrix of the intervertebral disc structures contains many molecules also found in cartilage. The extremely polyanionic proteoglycans play a central role, particularly in the nucleus, by creating an osmotic environment leading to retention of water and ensuing resistance to deformation—important for the resilience of the tissue. Another major structural entity particularly impor

Sixty-nine consecutive patients ( median age 54 years) were prospectively enrolled in a single-institution protocol for allogeneic transplantation with adjusted non-myeloablative fludarabine - melfalan-based conditioning including cyclosporin A and MMF, and one of three modes of serotherapy. Thirty-one donors (45%) were unrelated. The first cohort of 29 had ATG (Thymoglobulin 2 mg/kg x 3 days), th

BRCA1 mutations predispose to early-onset breast cancer. We previously reported an association between absence of the common IGF1 19 CA-repeat allele (IGF1-19/-19) and being a BRCA1 mutation carrier in young women from breast cancer high-risk families. Others have reported a four-fold risk of premenopausal breast cancer in women with a family history and the IGF1-19/-19 genotype. The aim of this s

The stratospheric ozone layer, which protects the biosphere from biologically active (mostly harmful) ultraviolet-B (UV-B) solar radiation, thinned during the latter half of the 20th century. In this paper some of the effects of UV-B radiation on cryptogams (cyanobacteria, algae, lichens, mosses, liverworts, pteridophytes and fungi) are reviewed. Effects vary among species, and therefore changes i

The genetic variation of Duddingtonia flagrans, which has become a promising biocontrol agent of animal parasitic nematodes, was investigated in a worldwide collection of 22 isolates. We analysed the sequence variation in four nuclear genes, tubA (beta-tubulin), CMD1 (calmodulin), EF1alpha (translation elongation factor 1alpha), and PII (extracellular serine protease). 1428 aligned base pairs (bp)

The use of beam data for open photon fields when calculating absorbed dose distributions for beams with wedge filters has been studied. The depth doses for beams with wedge filters are changed through beam hardening and the dose maximum can be shifted; both these changes result in errors in the final dose calculations of several per cent if open beam data are used. The errors are larger for 6 MV t

The prevalence of HCV genotypes in four republics of the former Soviet Union (Russia, Belarus, Moldova, and Uzbekistan) was investigated. Overall, 197 HCV isolates from 66 blood donors and 131 patients with chronic hepatitis were typed. Viral sequences from sera of infected subjects were amplified by nested RT-PCR using primers from the core region and typed by one or two techniques: (1) DNA enzym

Purpose. The aim of this study was to describe the treatment from other people as experienced by people with moderate or severe traumatic brain injury (TBI) and their close relatives. Method. Twelve people with moderate or severe TBI and eight of their close relatives were interviewed. The interviews were analysed using thematic content analysis. Results. The results were described by the means of

The aim was to elucidate families' lived experience during a child's cancer treatment. Interviews were conducted with members of 11 affected families. A hermeneutical phenomenological approach was chosen. "Focus on the ill child-An everyday struggle" emerged as an essential theme. The families' lived experience of daily life was described as "feeling drained," "disrupting family life," "feeling lo

Genotypic and phenotypic analyses were carried out to clarify the taxonomic position of the naturally transformable Acinetobacter sp. strain ADP1. Transfer tDNA-PCR fingerprinting, 16S rRNA gene sequence analysis, and selective restriction fragment amplification (amplified fragment length polymorphism analysis) indicate that strain ADP1 and a second transformable strain, designated 93A2, are membe

During development, information about the three-dimensional shape and mechanical properties of the body is laid down in the synaptic connectivity of sensorimotor systems through unknown adaptive mechanisms. In spinal reflex systems, this enables the fast transformation of complex sensory information into adequate correction of movements. Here we use a computer simulation to show that an unsupervis

Three different series of xylosylated naphthoic acid-amino acid conjugates containing one or two amino acid residues were synthesized for the investigation of glycosaminoglycan priming and potential use as anti-tumor drugs. All xylosylated naphthoic acid-conjugates inhibited the growth of normal lung fibroblasts to some extent, whereas the growth of tumor derived T24 carcinoma cells was not affect

We have recently described frequency-dependent effects of mobile phone microwaves (MWs) of global system for mobile communication (GSM) on human lymphocytes from persons reporting hypersensitivity to electromagnetic fields and healthy persons. Contrary to GSM, universal global telecommunications system (UMTS) mobile phones emit wide-band MW signals. Hypothetically, UMTS MWs may result in higher bi

The legacy of Nisbett and Wilson's classic article, Telling More Than We Can Know: Verbal Reports on Mental Processes (1977), is mixed. It is perhaps the most cited article in the recent history of consciousness studies, yet no empirical research program currently exists that continues the work presented in the article. To remedy this, we have introduced an experimental paradigm we call choice bli

A previous study has shown that serum levels of the active vitamin D metabolite 1,25-(OH)2-vitamin D were inversely related to blood pressure levels while the prohormone 25-OH-vitamin D was found to be related to insulin metabolism. Also other clinical and experimental data support the view that vitamin D metabolism is involved in blood pressure regulation and other metabolic processes. The presen
