A pyridoxamine equivalent, 9-aminothioxanthene 10,10-dioxide, has been designed that is capable of affording transamination in good to excellent yields of natural as well as artificial amino acids. Amidines and guanidines in catalytic amounts were capable of performing [1,3]-proton transfer in the imines under mild conditions, whereas various simple amines failed. The use of chiral catalysts resul
Aim To assess at a broad scale the vulnerability of Mediterranean vegetation to alien plant invasion under different climatic and disturbance scenarios. Location We simulated the vegetation biogeography and dynamics on five of the main islands of the Mediterranean Basin: Mallorca, Corsica, Sardinia, Crete and Lesvos. Methods We used LPJ-GUESS, a generalized ecosystem model based on dynamic process
OBJECTIVE: We sought to evaluate the management of women with abnormal cytology in terms of subsequent risk of invasive cervical cancer. STUDY DESIGN: The screening histories of all invasive cervical cancer cases diagnosed in Sweden 1999-2001 and of 5 population-based controls per case were reviewed. In all, 159 patients and 258 control subjects aged < 67 years had an abnormal smear result 0.5-6.5
Objective - To analyse potential gender differences in cardiovascular risk factors and treatment patterns, reflecting clinical practice in secondary prevention. Design - Observational national study during 3 years of patients eligible for secondary prevention of coronary heart disease (CHD). Setting - Fifty-two healthcare districts in Sweden, involving primary health care and hospitals in collabor
Issues: HIV/hepatitis coinfection in Europe; WHO European clinical protocols on the management of people coinfected with HIV/AIDS and hepatitis B or C (HBV or HCV); stakeholder recommendations for better HCV services. Introduction: The increasing availability of highly active antiretroviral therapy throughout Europe and central Asia has changed comorbidity and mortality patterns among people livin
The Serial Color Word Test was administered at baseline to 253 hypertensive men participating in the prospective cohort study of cardiovascular diseases "Men born in 1914" in Malmo, Sweden. This test of psychological adaptation to a stressful encounter was used to investigate whether susceptibility to stress moderates the risk of a cardiac event in association with hypertension. Adaptive behavior,
Sera from patients with sexually acquired reactive arthritis (SARA) with antibodies reacting with C. trachomatis and C. pneumoniae (group 1; n = 20) and also with C. psittaci (group 2; n = 19) were analyzed for antibody specificity. Sera from group 2 reacted significantly more often with C. trachomatis serotype E, H and K and had higher antibody titers to serotype E, as tested by microimmunofluore
The MYCN proto-oncogene is frequently amplified in a subgroup of highly aggressive neuroblastomas. The molecular mechanism(s) by which the overexpressed MYCN contributes to an aggressive tumor cell behavior is not well understood. Recently, it was reported that the ID2 gene is a direct target for the MYCN and MYC transcription factors, and that ID2 expression and MYCN amplification correlate posit
1. We examined the response to chemical cues from fish and crayfish, two predators with contrasting feeding modes, and their single and combined effect on shell morphology in the freshwater snail Radix balthica. 2. Snails were subjected to four treatments: tench (Tinca tinca), signal crayfish (Pacifastacus leniusculus), a combination of tench and signal crayfish and no predators (control). Shell
Background: The aim of this study was to explore the feasibility of using a technique based on artificial neural networks for quality assurance of image reporting. The networks were used to identify potentially suboptimal or erroneous interpretations of myocardial perfusion scintigrams (MPS). Methods: Reversible perfusion defects (ischaemia) in each of five myocardial regions, as interpreted by on
Background— Inflammation is an important pathophysiological feature of abdominal aortic aneurysms (AAA). Whether elevated levels of inflammation-sensitive plasma proteins (ISPs) predict the long-term risk of fatal or repaired AAA is largely unknown. Methods and Results— Five ISPs (fibrinogen, orosomucoid, {alpha}1-antitrypsin, haptoglobin, and ceruloplasmin) were measured in 6075 healthy men, mea
The in-line ultrasound Doppler-based UVP-PD rheometry method was evaluated for non-invasive, real-time theological characterization of complex model- and industrial suspensions. The method is based on the combination of ultrasound velocity profile (UVP) and pressure drop (PD) measurements. Experiments were carried out in pressure driven, steady shear flow at different volumetric flow rates in a fl
Aim. This paper reports a study to investigate coping strategies and sense of coherence in relation to gender, the extent of care, caregiving activities and health-related quality of life in a population-based sample of caregivers aged 75 and over. Background. Caring for another person can be stressful both emotionally, and caregiver burden may affect quality of life in a negative way for the car
Nutritional classification of dietary saccharides considers as indigestible saccharides those that are incompletely or not absorbed in small intestine. Resistant starch (RS) as a part of dietary fibre (DF) is a type of indigestible saccharide. The addition of natural RS from some fruits, legumes or cereals to commonly eaten starchy foods is a good alternative to increase the DF intake representing
During embryonic development and adult life a wide range of cell behaviors such as differentiation, proliferation and migration are in effect to maintain tissue integrity and function. An integral part of these dynamic processes is the interplay between the cells and their environment, i.e. the extracellular space. Complex polysaccharides, such as dermatan sulfate play a key role in these processe
