An aqueous system containing fluorapatite (Ca-5(PO4)(3)F), (FAP) and varying amounts of goethite (alpha-FeOOH) has been investigated. Batch experiments and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy were used to monitor the dissolution products of FAP, as well as the adsorption, and phase transformation of phosphate at the goethite surface over a period of 129
The aim of the present case-control study was to investigate the role of migraine as a potential risk factor for a delayed ischaemic neurological deficit (DIND) after subarachnoid haemorrhage (SAH). A telephone interview was performed in patients or their relatives to determine the prevalence of migraine. Thirty-six women aged < 60 years had SAH with Hunt & Hess grade I-III and DIND (group A).
Two well dated Holocene sediment records bordering the Denmark Strait region have been used to reconstruct past climate variability. The content of biogenic silica, clastic and organic material and moss in a lacustrine record from Lake N14 has been used to infer past variability in precipitation and temperature in southern Greenland. Sedimentologic and petrologic composition of sand in a shelf sed
Background Patch test reactivity to nickel varies over time. To what extent this variation is associated with fluctuations in the T-cell reactivity to nickel is not known. Objectives Our aim was to investigate the relationship between variation over time in the patch test and the systemic T-cell reactivity to nickel. Methods Patients (n = 15) with a history of contact allergy to nickel were subjec
In order to identify integral proteins and peripheral proteins associated with the plasma membrane, highly purified Arabidopsis plasma membranes from green tissue (leaves and petioles) were analyzed by mass spectrometry. Plasma membranes were isolated by aqueous two-phase partitioning, which yields plasma membrane vesicles with a cytoplasmic-side-in orientation and with a purity of 95%. These vesi
Simultaneous overexpression of c-erbB-2 and p53 has been reported to be prognostically unfavorable in breast cancer. Herein, we show that concurrent overexpression of these 2 proteins is associated with a marked reduction in the relative fraction of cells in G(1) phase of the cell cycle, indicating an accelerated cell cycle progression. Using an immunohistochemical approach, we examined 261 cases
In prospective cohort studies, person-time time is calculated from baseline until the first definite event occurs or until censoring. A way to correctly identify and date definite events when only routine registers are available is to retrieve all hospital discharge notes and death certificates with a diagnosis of probable event and perform a consecutive revision. It is important to detect all pos
Background: The aim was to investigate ethnic differences in daily smoking in Malmö, Sweden, and whether these differences could be explained by psychosocial and economic conditions. Methods: The public health survey in Malmö 1994 is a cross-sectional study. A total of 5,600 individuals aged 20–80 years were randomly chosen to respond to a postal questionnaire. The participation rate was 71%. The
Lung cancer has emerged as one of the leading causes of cancer death in most developed and many developing countries of the world. In the absence of effective screening and early detection methods of lung cancer and overall poor prognosis, the 5-year survival following treatment has not improved significantly over the last two decades. It is hoped that the risk of the disease can be minimized by p
Analyses of testate amoebae and aeolian sediment influx (ASI) were used to reconstruct effective humidity changes and aeolian activity in the coastal zone of south-west Sweden. Cores were taken from an ombrotrophic peat sequence from the Undarsmosse bog. Since both types of analysis were carried out on the same core, a direct comparison between humidity fluctuations in the bog and aeolian activity
The aim of this study was to describe the course of untreated or conservatively treated arthrosis of the knee joint. Of 265 patients presenting with knee pain who had weightbearing radiographs taken between 1970 and 1973, 132 (33 men and 99 women) responded to and participated in a clinical followup 20 years later using the Hospital for Special Surgery score and new weightbearing radiographs. Arth
In this article we describe Tibetan indigenous women's perceptions and experiences of their own health and life situation in Shichuan Province, China. Fifteen focus group discussions (FGDs) and 10 interviews were conducted. Repeat FGDs were used to empower the women and as a tool to collect data. Content analysis was used to analyze the data, and three subthemes were identified: 'shouldering respo
This study describes the outcome of patients receiving haematopoietic stem cell transplantation (HSCT) to treat severe refractory autoimmune cytopenia. The registry of the European Group of Blood and Marrow Transplantation holds data on 36 patients receiving 38 transplants, the first transplant was autologous for 27 and allogeneic for nine patients. Patients had autoimmune haemolytic anaemia (auto
Basic helix-loop-helix PAS domain proteins form a growing family of transcription factors. These proteins are involved in the process of adaptation to cellular stresses and environmental factors such as a change in oxygen concentration. We describe the identification and characterization of a recently cloned PAS domain protein termed Npas4 in ischemic rat brain. Using gene expression profiling fol
We investigate the spectral and temporal structure of high harmonic emission from argon exposed to an infrared laser field and its second harmonic. For a wide range of generating conditions, trains of attosecond pulses with only one pulse per infrared cycle are generated. The synchronization necessary for producing such trains ensures that they have a stable pulse-to-pulse carrier envelope phase,
We compare assimilation and respiration rates, and water use strategies in four divergent ecosystems located in cold-continental central Siberia and in semi-arid southern Africa. These seemingly unrelated systems have in common a harsh and highly seasonal environment with a very sharp transition between the dormant and the active season, with vegetation facing dry air and soil conditions for at le
Smoking is a well-established risk factor for cardiovascular disease. Studies have indicated that smoking may outweigh the benefit of blood pressure (BP) control. Our aim was to compare cardiovascular risk factors in smokers vs non-smokers from a national sample of treated hypertensives. Data were collected on smoking habits, BP control, total and low-density lipoprotein (LDL) cholesterol, diabete
