Genetic and expression profiles of squamous cell carcinoma of the head and neck correlate with cisplatin sensitivity and resistance in cell lines and patients

Purpose: The choice of treatment for squamous cell carcinoma of the head and neck (SCCHN) is still primarily based on the tumor-node-metastasis classification. However, it is reasonable to believe that biological profiles of SCCHN may be independently associated with response to therapy. The aim of the present study was to examine genetic changes and gene expression profiles that might correlate w

Individualized screening interval for prostate cancer based on prostate-specific antigen level - Results of a prospective, randomized, population-based study

Background: The aim of the present study was to evaluate the future cumulative risk of prostate cancer in relation to levels of prostate-specific antigen (PSA) in blood and to determine whether this information could be used to individualize the PSA testing interval. Methods: The study included 5855 of 9972 men (aged 50-66 years) who accepted an invitation to participate in a prospective, randomiz

Effect of two novel CGRP-binding compounds in a closed cranial window rat model

We investigated the in vivo effects of two novel calcitonin gene-related peptide (CGRP) binding molecules in the genuine closed cranial window model in the rat. The RNA-Spiegelmer (NOX-C89) and the monoclonal CGRP antibody are CGRP scavengers and might be used as an alternative to CGRP-receptor antagonists in the treatment of migraine. Rats were anaesthetized and a closed cranial window establishe

Slepian models for chi²-processes with dependent components with application to envelope upcrossings

A Slepian model for the local behaviour near the level upcrossings of a chi²-process with dependent Gaussian components is presented. In case of independent components, this model is shown to take on a rather simple form, thereby simplifying earlier results by Aronowich and Adler. The Slepian model is applied to the envelope of a stationary Gaussian process and used to approximate the probabilit

Selective supercritical fluid extraction as a tool for determining the PCB fraction accessible for uptake by chironomid larve in a limnic sediment

Selective supercritical fluid extraction (SFE) at 40 degrees C, 400 bar and 60 min was used to selectively remove bioavailable PCBs from a naturally contaminated limnic sediment. The extraction decreased the sediment concentrations of the nine studied PCBs by 54% (on average). Chironomid larvae were thereafter cultured in pre-extracted sediment as well as in untreated sediment to study the differe

Influence of elevated CO2 on the fungal community in a coastal scrub oak forest soil investigated with terminal-restriction fragment length polymorphism analysis

Sixteen open-top chambers (diameter, 3.66 m) were established in a scrub oak habitat in central Florida where vegetation was removed in a planned burn prior to chamber installation. Eight control chambers have been continuously exposed to ambient air and eight have been continuously exposed to elevated CO2 at twice-ambient concentration (similar to700 ppm) for 5 years. Soil cores were collected fr

Ambient Air Contamination by Micron and Submicron Particles from Welding Operations

Impactor sampling and PIXE analysis constitute a good combination in detecting the influence of fugitive emission and ventilation air on ambient air quality. In total filter samples heavier natural particles mask the increase in mass due to the smaller industrial particles. Multielemental analysis of many samples is important in finding unknown sources and in evaluating the effect of all the sourc

Higher risk of colic in infants of nonmanual employee mothers with a demanding work situation in pregnancy.

In this population-based study, we assessed the relation between socioeconomic and psychosocial conditions in 1,094 pregnant women and subsequent infantile colic by means of self-administered questionnaires measuring exposures in the 17th pregnancy week and telephone interviews at infant age 5 weeks. There was a higher risk of colic in infants born to younger mothers, mothers with low instrumental

Gut associated lymphoid tissue primed CD4+ T cells display CCR9 dependent and independent homing to the small intestine.

CD4(+) T-cell entry to the intestinal mucosa is central to the generation of mucosal immunity as well as chronic intestinal inflammation, yet the mechanisms regulating this process remain poorly defined. Here we show that murine small intestinal CD4+ lamina propria lymphocytes express a heterogeneous but restricted array of chemokine receptors including CCR5, CCR6, CCR9, CXCR3, and CXCR6. CD4+ T-c

Social capital, the miniaturization of community and cannabis smoking among young adults.

Objectives: The impact of social participation, trust and the miniaturization of community, i.e. the combination of high social participation and low trust, on cannabis smoking was investigated. Methods: The 2000 public health survey in Scania is a cross-sectional study. A total of 13,715 persons aged 18–80 years, of which 3,978 persons aged 18–34 years were included in this study, answered a pos

Socioeconomic position, macroeconomic environment and overweight among adolescents in 35 countries

Objective: It is important to understand levels and social inequalities in childhood overweight within and between countries. This study examined prevalence and social inequality in adolescent overweight in 35 countries, and associations with macroeconomic factors. Design: International cross-sectional survey in national samples of schools. Subjects: A total of 11-, 13- and 15-year-olds from 35 co

A desymmetrization route to fused Troger's base analogues: Synthesis, isolation, and characterization of the first anti-anti diastereomer of a fused tris-Troger's base analogue

A desymmetrization route to fused Troger's base analogues was developed. In this way, the synthesis of the first example of an anti-anti diastereomer of a fused tris-Troger's base analogue was accomplished. The resulting compound 5b is a nonlinear symmetric regioisomer obtained from p-bromoaniline in 7% yield. The corresponding syn-anti diastereomer 5a was obtained in 4% yield.

Structures and stabilities of Cd(II) and Cd(II)-phthalate complexes at the goethite/water interface

The complexation of Cd(II) and Cd(II)-phthalate at the goethite/water interface were investigated by EXAFS and IR spectroscopy, by batch adsorption experiments and by potentiometric titrations at 298.15 K. The EXAFS spectra showed Cd(IT) to form only inner-sphere corner-sharing complexes with the goethite surface sites in the presence and absence of phthalate. EXAFS spectra also showed the presenc

Fracture incidence in GH-deficient patients on complete hormone replacement including GH

Fracture risk in GHD patients is not definitely established. Studying fracture incidence in 832 patients on GH therapy and 2581 matched population controls, we recorded a doubled fracture risk in CO GHD women, but a significantly lower fracture risk in AO GHD men. Introduction: The objective of this study was to evaluate fracture incidence in patients with confirmed growth hormone deficiency (GHD)

The importance of atmospheric deposition, charge and atomic mass to the dynamics of minor and rare elements in developing, ageing, and wilted leaves of beech (Fagus sylvatica L.)

The amounts of sixty elements in developing, maturing, senescent and wilting leaves, and in the wintering dead leaves attached to the branches, are reported for a beech (Fagus sylvatica) forest on mor Podzol in south Sweden, a site with no local sources of pollution or geological anomalies. The amounts (contents per leaf) of K (potassium), Rb (rubidium), Cs (caesium), Cu (copper) and P (phosphorus

Psychosocial work conditions, unemployment, and generalized trust in other people: A population-based study of psychosocial health determinants

The association between psychosocial work conditions, unemployment, and generalized trust was investigated. The health survey in Skane is a cross-sectional postal questionnaire study with a 59% participation rate. A total of 5,180 persons that belonged to the work force and the unemployed were included. Logistic regression models were used to investigate the associations between psychosocial facto
