Is the variability of nickel patch test reactivity over time associated with fluctuations in the systemic T-cell reactivity to nickel?

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

Arabidopsis Plasma Membrane Proteomics Identifies Components of Transport, Signal Transduction and Membrane Trafficking

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

Concurrent overexpression of p53 and c-erbB-2 correlates with accelerated cycling and concomitant poor prognosis in node-negative breast cancer

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

Comparison of different procedures to identify probable cases of myocardial infarction and stroke in two Swedish prospective cohort studies using local and national routine registers

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

Ethnic differences in daily smoking in Malmö, Sweden. Varying influence of psychosocial and economic factors.

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

Black tea extract can modulate protein expression of H-ras, c-Myc, p53, and Bcl-2 genes during pulmonary hyperplasia, dysplasia, and carcinoma in situ

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

Increased aeolian activity during humidity shifts as recorded in a raised bog in south-west Sweden during the last 1700 years

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 natural course of arthrosis of the knee

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

Endurance of Aloneness Among Tibetan Indigenous Women in Western China: Application of Repeat Focus Group Discussions as a Tool for Empowerment and for Data Collection

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

Haematopoetic stem cell transplantation for refractory autoimmune cytopenia

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

Npas4, a novel helix-loop-helix PAS domain protein, is regulated in response to cerebral ischemia

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

Attosecond pulse trains generated using two color laser fields

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,

Water use strategies and ecosystem-atmosphere exchange of CO2 in two highly seasonal environments

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

Hypertensive smokers have a worse cardiovascular risk profile than non-smokers in spite of treatment - A national study in Sweden

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

Law and participation

The main problem discussed in this paper is that the legal system might be dysfunctional to various political participatory ambitions. Participation implies inclusion, but we see examples of exclusion that originate from internal operations of the legal system. Considering the many instances of participatory instruments embedded in legal frameworks in many sectors of society, it is important to as

Peripheral serotonergic markers in patients with suicidal behavior

Peripheral serotonergic parameters were studied in 17 patients with a history of suicidal behavior and in 17 age- and sex-matched healthy controls. Serotonin2 receptor function in platelets, measured as serotonin-induced [32P]phosphatidylinositol 4,5-bisphosphate hydrolysis, was significantly higher in patients than in age- and sex-matched controls. Increased serotonin2 receptor transduction was n

Exercise during growth and bone mineral density and fractures in old age

If exercise is to be recommended during growth, benefits in bone mineral density (BMD) must be maintained in old age and shown to prevent fractures. Our cross-sectional study of soccer players suggests that a high BMD is no longer recorded after retirement and fracture frequency is no less than predicted in old age.
