Cytogenetic findings in 33 osteosarcomas

Thirty-three osteosarcomas (OS) were analyzed cytogenetically. Clonal chromosome changes were detected in 17 cases. Six tumors had chromosome numbers in the diploid range, 6 in the triploid range, 1 in the tetraploid range and 1 in the pentaploid range, while 3 tumors had multiple clones with different ploidy levels. Including the present 17 tumors, a total of 27 OS with clonal aberrations have be

"A Token of Gratitude"? A Morally Ambiguous Case of Bribery

The phenomenon of bribery is characterized by its elastic features, both morally and legally. This study sets out to investigate a court case of bribery: how the people involved construct and argue for their particular version. A single case of bribery is chosen in order to clarify the range and potential of various descriptions of the very same event. The material consists of interviews with the

Long-term vegetation history of a Picea abies stand in south-western Norway : implications for the conservation of biological values

The development of a forest stand in south-eastern Norway during the last 9000 years is investigated by pollen and charcoal analyses. The aims are to identify factors that have influenced current biodiversity, which includes the lichen Usnea longissima, and examine the immigration and establishment of the current dominant tree Picea abies. Fire has been a variable but major disturbance factor at t

CYP17 genotype is associated with short menstrual cycles, early oral contraceptive use and BRCA mutation status in young healthy women

The CYP17 gene is involved in steroid hormone metabolism and has been proposed as a low penetrance gene for breast cancer. We aimed to investigate the associations between the CYP17 genotype and breast cancer risk factors, such as age at menarche, menstrual cycle length, oral contraceptive (OC) use, and BRCA mutation status among 258 healthy young women, aged <= 40, from 158 breast cancer high-ris

Cutaneous Human Papillomaviruses Persist on Healthy Skin.

Cutaneous human papillomaviruses (HPVs) are frequently found in healthy skin and have also been implicated in non-melanoma skin cancer. For genital HPV types, a persistent infection with one of the high-risk types is a prerequisite for the development of cervical cancer. However, there is only limited data on whether infections with cutaneous HPV types persist over time. Serial forehead swab sampl

The STAT4 gene influences the genetic predisposition to systemic sclerosis phenotype

The aim of this study was to investigate the possible role of STAT4 gene in the genetic predisposition to systemic sclerosis (SSc) susceptibility or clinical phenotype. A total of 1317 SSc patients [896 with limited cutaneous SSc (lcSSc) and 421 with diffuse cutaneous SSc (dcSSc)] and 3113 healthy controls, from an initial case-control set of Spanish Caucasian ancestry and five independent cohorts

Processing of seminal plasma hCAP-18 to ALL-38 by gastricsin - A novel mechanism of generating antimicrobial peptides in vagina

The human cathelicidin, hCAP-18, is expressed both in neutrophils and in epithelial cells. hCAP-18 is processed to the antimicrobial peptide LL-37 by proteinase 3 in neutrophils. hCAP-18 is highly expressed in the epididymis with a subsequent high concentration in seminal plasma where the protein is present in its unprocessed and antimicrobially inactive form. We report here that hCAP-18 in semina

Microfluidic biosensing systems - Part I. Development and optimisation of enzymatic chemiluminescent mu-biosensors based on silicon microchips

Chemiluminescent (CL) enzyme-based flow-through microchip biosensors (mu-biosensors) for detection of glucose and ethanol were developed for the purpose of monitoring real-time production and release of glucose and ethanol from microchip immobilised yeast cells. Part I of this study focuses on the development and optimisation of the mu-biosensors in a microfluidic sequential injection analysis (mu

Synovial fluid level of aggrecan ARGS fragments is a more sensitive marker of joint disease than glycosaminoglycan or aggrecan levels: a cross-sectional study

Introduction Aggrecanase cleavage at the (392)Glu-(393)Ala bond in the interglobular domain (IGD) of aggrecan, releasing N-terminal (393)ARGS fragments, is an early key event in arthritis and joint injuries. Here, we use a quantitative immunoassay of aggrecan ARGS neoepitope fragments in human synovial fluid to determine if this cleavage-site specific method better identifies joint pathology than

Access to highly active antiretroviral therapy (HAART) for injecting drug users in the WHO European Region 2002-2004

Providing equitable access to highly active antiretroviral treatment (HAART) to injecting drug users (IDUs) is both feasible and desirable. Given the evidence that IDUs can adhere to HAART as well as non-IDUs and the imperative to provide universal and equitable access to HlV/AlDS treatment for all who need it, here we examine whether IDUs in the 52 countries in the WHO European Region have equita

An atypical intra-platform environment and biota from the Silurian of Gotland, Sweden

A condensed shale from the middle Silurian of Gotland (Sweden) is herein described with regard to its biotic and environmental significance. The fauna is characterised by an overall low diversity and anomalous abundance patterns, notably a mass-occurrence of scolecodonts. Other elements include abundant chitinozoans, dendroid and graptoloid graptolites, conodonts, eurypterids, and the brachiopod L

Effects of low-dose X-irradiation on mouse-brain aggregation cultures

Biochemical and morphological differentiation in reaggregating mouse-brain cell cultures after low-dose radiation (0.5 Gy) in vitro was studied. Cells were irradiated on culture day 2, corresponding to embryonic day 15-16, and different glial and neuronal markers were followed through development to postnatal day 40. The shape and size of irradiated aggregates were more irregular and smaller compa

Binding of adenosine to pendant phenylboronate groups of thermoresponsive copolymer: a quantitative study

Binding of adenosine to the thermosensitive copolymer of N-isopropylacrylamide and 3-(acrylamido)aminophenylboronic acid (82:18, m ($) over bar (n)=47000 g center dot mol(-1)) was studied by equilibrium dialysis at 22 degrees C and 37 degrees C, in a 0.1 m glycine buffer containing 0.1 m NaCl at pH 9.2. The copolymer exhibited a the phase transition temperature (T-p) of 26.5 degrees C under the ab
