Using near-infrared femtosecond absorption spectroscopy, we have determined the S-1 energies of the carotenoids spheroidene and rhodopin glucoside in LH2 complexes of purple bacteria. The S-1 energies in the LH2 complexes yield values of 13400 +/- 100 cm(-1) for spheroidene and 12550 +/- 150 cm(-1) for rhodopin glucoside, which are very close to the S-1 energies obtained for both carotenoids in so

Kan sociologin användas till att förstå filosofiskt tänkande? De senaste decennierna har en ny typ av studie växt fram som studerar filosofiskt tänkande ur ett sociologiskt perspektiv. På engelska benämns denna desciplin sociology of philosophy respektive sociology of philosophical knowledge. En lämplig svensk översättning torde bli filosofisociologi. Filosofisociologisk forskning syftar till at

This study investigates the toxic effect of E(2)nonenal (trans-2-nonenal, T2N) and its conjugate with horse muscle myoglobin (Mb) tested on murine cell line L929 and human cell line A549, as well as the genotoxic effect of these compounds assayed by measuring of micronuclei in human cells K562. It is an aldehyde, which is occurring as the substance responsible for an off flavour in aged beers, but

The prevalence of abdominal aortic aneurysm (AAA) in a defined population of elderly men and its correlation to some risk factors were studied in the population cohort "men born in 1914 from Malmo". A total of 499 were invited to attend and 375 (75%) did so. The aorta could be visualised with ultrasound in 364 patients, 39 (10.7%) of whom had aneurysmal changes. The presence of an AAA was related

Context: Insulin-stimulated glucose uptake in skeletal muscle is mediated through translocation of the insulin-sensitive glucose transporter 4 ( GLUT4)-containing vesicles to the plasma membrane. Thus, skeletal muscle GLUT4 content plays an important role in whole-body insulin sensitivity. Objectives: The objectives of this study were 1) to examine the relative impact of genetic vs. environmental

We review the present status of the hadronic light-by-light contribution to muon g - 2 and critically compare recent calculations.

This paper gives an overview of the cadmium (Cd) situation in agricultural systems and human exposure in Sweden. Cadmium levels in agricultural soils (the plow layer) increase by 0.03% to 0.05% per year. Feed can give substantial contributions of Cd to local agricultural systems. Effects on human kidney function are indicated by some measurements already at today's exposure levels. If food product

PURPOSE: Hereditary prostate cancer accounts for 5% to 10% of all prostate cancer cases. We assessed clinical characteristics and survival in patients with hereditary prostate cancer MATERIALS AND METHODS: The study comprised 201 patients from 62 Swedish hereditary prostate cancer families and 402 controls with prostate cancer who were matched for age and calendar year at diagnosis, and the hospit

When water is coadsorbed with oxygen at coverages above 0.25ML an intact water species is observed in high resolution X-ray photoelectron spectroscopy up to 220 K, which is significantly more stable than intact water on the clean surface. The presence of this species causes a shift in the O 1s binding energy of the pre-adsorbed oxygen, which indicates the formation of hydrogen bonds between the tw

Endotoxin was measured in air and dust samples collected during four commercial aircraft flights. Samples were analyzed for endotoxin biological activity using the Limulus assay. 3-hydroxy fatty acids (3-OH FA) of carbon chain lengths C10:0-C18:0 were determined in dust by gas chromatography-ion trap tandem mass spectrometry. The geometric mean (geometric standard deviation) endotoxin air level wa

he study focuses on two elicitation methods for language sampling in children with language impairment: conversation and narration. It has been noted in other studies on different clinical groups that language elicited in different speaking contexts varies in aspects such as MLU, fluency and syntactic complexity. The purpose of this study was to compare genre effects on different aspects of langua

BACKGROUND: The brain-derived protein S100B has been shown to be a useful marker of brain injury of different etiologies. Cognitive dysfunction after cardiac surgery using cardiopulmonary bypass has been reported to occur in up to 70% of patients. In this study we tried to evaluate S100B as a marker for cognitive dysfunction after coronary bypass surgery with cardiopulmonary bypass in a model wher

The deformation of a drop flowing along the centre streamline of a four-roll mill (4RM) has been investigated. The velocities and elongation rates along the centre streamline in the 4RM were measured using particle tracking velocimetry. The deformation and position of the deforming drops were photographed with a video camera. A dynamic, one-dimensional, analytical simulation model describing the d

This article presents the second study in a series that has been designed to manifest the emergence of consciousness and to measure developed competence. Its major aim has been to demonstrate that an invariant formulation of the Agent-action-Objective model and an analysis of its A-O kinematics have the capacity to re-produce contour similarity over time. Within the studied evolutionary-developmen

OBJECTIVE: To determine whether the combined use of Lerner's morphologic score and color Doppler ultrasound examination results in better discrimination of benign and malignant adnexal masses than the use of Lerner's score alone or Doppler variables alone. DESIGN: One hundred and seventy-three consecutive women with a pelvic mass judged clinically to be of adnexal origin underwent preoperative ult
