The influence of major surgery on HIV disease progression and decline in CD4+ cell count was evaluated in 23 seropositive haemophilia patients. 24 HIV-infected patients served as non-operated controls. In addition, 32 age-matched seronegative subjects were included. The follow-up time was up to 5 years. During the course of the study, eight of the operated (35%) and 11 of the non-operated (48%) su
Promoter methylation is a common phenomenon in tumours, including haematological malignancies. In the present study, we investigated 36 cases of high hyperdiploid (> 50 chromosomes) acute lymphoblastic leukaemia (ALL) with methylation-specific multiplex ligase-dependent probe amplification to determine the extent of aberrant methylation in this subgroup. The analysis, which comprised the promoters
Between May and December 1996, monthly samples of surface sediment (0-1 cm), settling matter, and water were taken at a shallow site and a deep site in each of two consecutive Hg-polluted riverine lakes. In the upper lake, the sediment was polluted also with cellulose fiber. Both hypolimnia turned anoxic, but sulfide was detected only in the upper lake. When sulfide appeared, hypolimnetic methyl m
Objectives: To assess the changes in HIV prevalence and incidence between 1996 and 2006 in urban areas of Bissau. Design: A cross-sectional survey of 384 randomly selected houses within a community-based follow-up study of HIV-1 and HIV-2. Methods: A total of 3242 individuals aged at least 15 years were eligible for inclusion. Participants were interviewed about behavioral and socio-economic facto
In this study, we first determined the low molecular weight dissolved organic carbon (LMW DOC) concentration-dependent kinetics of soil respiration in a temperate grassland soil sampled on successive occasions. We then used the established relationship to estimate in situ LMW DOC concentrations from basal respiration measurements. C-14-labelled glucose was used as a model substrate and was added t
Global warming and energy shortage have aroused a great interest in climate responsive strategies of vernacular dwellings during recent years. This study focuses on a qualitative analysis of ancient dwellings located in the village of Xinye, in the hot summer and cold winter region of China. Furthermore, a typical ancient dwelling located in the village was selected for assessment of its indoor th
We investigated whether aminoguanidine (AG), an inhibitor of advanced glycated end product formation, or probucol (PB), a free radical scavenger, could influence signs of glomerular and distal tubular function and morphological changes in kidneys of male Wistar rats after 6 months of streptozocin (STZ)-induced diabetes. Diabetic rats had a higher kidney weight/body weight ratio (P<.001), but neith
In a previous experimental study, a novel method for in vivo dosimetry has been investigated, based on radioluminescence (RL) and optically stimulated luminescence (OSL). However, because of (fie large difference in atomic composition between the detector material and the breast tissue, relatively large energy dependence in low-energy X-ray beams can be expected. In the present work, the energy de
Breast cancer is one of the most common cancer forms affecting many women. The disease nevertheless has widely varying behavior and therefore patient outcome, and an important undertaking is to define and understand the molecular mechanisms behind these actions. Defects in the G1/S transition in the cell cycle affect both tumor proliferation and the fidelity of check points responsible for chromos
Background and Purpose - Regular endurance exercise has been shown to reduce the age-related increase in arterial stiffness that is thought to contribute to cardiovascular risk. The aim of this study was to evaluate the influence of age and habitual physical activity on carotid artery wall thickness and stiffness in a population of young to middle-age subjects at low cardiovascular risk. Methods -
Greenhouse-grown clones of Viola tricolor were used to evaluate the importance of genetic effects on in vit ro pollen tube growth rate in relation to the influence of two environmental soil factors-pH and phosphorus content. After 1 mo in different soil treatments, individual pollen tube growth rate was affected by a genotype by phosphorus interaction, while it was unaffected by either main effect
BACKGROUND: Asthma-like symptoms, methacholine hyperresponsiveness, use of inhaled steroids, airway inflammation, and increased tenascin expression in the reticular basement membrane have been reported in competitive cross-country skiers. OBJECTIVE: To investigate the effect of inhaled budesonide, 400 mug twice daily, on indices of airway inflammation in 'ski asthma', defined as asthma-like sympto
Background: The Multiple Outcomes of Raloxifene Evaluation (MORE) study showed that treatment with raloxifene reduces the risk of vertebral fracture and breast cancer in postmenopausal women with osteoporosis. Objective: Based on the MORE study the aim of the present study was to assess the cost effectiveness of raloxifene (compared with no treatment) for the treatment of osteoporosis in postmenop
