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

Many of the morphological features of animals are considered to be adaptations to the habitat that the animals utilize. The habitats utilized by birds vary, perhaps more than for any other group of vertebrates. Here, we study possible adaptations in the morphology of the skeletal elements of the hind limbs to the habitat of birds. Measurements of the lengths of the femur, tibiotarsus and tarsometa

Cholecystokinin (CCK) is a hormone with well-known secretory and trophic effects on the pancreas. This also is true for epidermal growth factor (EGF), which acts in a paracrine and autocrine way. The aim was to study the influence of CCK on cell proliferation in rat pancreas with special reference to the expression of EGF, the EGF receptor, and phosphorylated tyrosine. Twenty-four male Sprague-Daw

Powdery mildew is a common disease of field pea, Pisum sativum L., and is caused by the ascomycete fungus Erysiphe pisi. It can cause severe damage in areas where pea is cultivated. Today breeders want to develop new pea lines that are resistant to the disease. To make the breeding process more efficient, it is desirable to find genetic markers for use in a marker-assisted selection (MAS) strategy

Staying aloft when hovering and flying slowly is demanding. According to quasi-steady-state aerodynamic theory, slow-flying vertebrates should not be able to generate enough lift to remain aloft. Therefore, unsteady aerodynamic mechanisms to enhance lift production have been proposed. Using digital particle image velocimetry, we showed that a small nectar-feeding bat is able to increase lift by as

The concentration of the protein S100B in serum is used as a brain damage marker in various conditions. We wanted to investigate whether a voluntary, prolonged apnea in trained breath-hold divers resulted in an increase of S100B in serum. Nine trained breath-hold divers performed a protocol mimicking the procedures they use during breath-hold training and competition, including extensive preapneic

Aims: To devise clinically applicable methods for assessing p53 and Ki67 immunohistochemical (IHC) reactivity in Barrett's oesophagus (BE) and to compare the interobserver agreement between these methods and routine haematoxylin and eosin (H&E) evaluation. Methods and results: One hundred and fifteen biopsies diagnosed as BE, selected from the files of the University Hospital MAS, Malmö, were

Hormone-sensitive lipase (HSL) is a key enzyme in fatty acid mobilization in many cell types. Two isoforms of HSL are known to date, namely HSLadi (84 kDa in rat) and HSLtes (130 kDa in rat). These are encoded by the same gene, with exons 1-9 encoding the parts that are common to both and an additional 5'-exon encoding the additional amino acids in HSLtes. HSL of various tissues, among these the i

Background: Evidence points to a link between systemic lupus erythematosus (SLE) and an increased risk of lung cancer. Our objective was to provide a brief report of the lung cancer cases from an SLE cohort, with respect to demographics, histology, and exposures to smoking and immunosuppressive medications. Methods: Data were obtained from a multi-site international cohort study of over 9500 SLE p

The judgment of the Court of First Instance in Microsoft represents a major success for the European Commission in its fight against abuses of a dominant position. The Court upholds the Commission's findings that Microsoft abused its dominant position by refusing to supply interoperability information that is indispensable for competitors to be able to viably compete in the work group server opera

Objective. The present study investigates the cross-sectional relationship between tobacco smoking and body fatness. Methods. This cross-sectional study consisted of 469,543 men and women who participated in the European Prospective Investigation into Cancer and Nutrition (EPIC) study between 1992 and 2000 providing anthropometric measurements and information on smoking. Adjusted multilevel mixed-

BACKGROUND: Polymorphisms of the vitamin D receptor (VDR) gene have been implicated in the genetic regulation of bone mineral density (BMD). However, the clinical impact of these variants remains unclear.OBJECTIVE: To evaluate the relation between VDR polymorphisms, BMD, and fractures.DESIGN: Prospective multicenter large-scale association study.SETTING: The Genetic Markers for Osteoporosis consor

In this study, we assessed the prevalence of self-rated post-traumatic stress in relation to reported trauma in an unselected primary care population. A total of 1113 out of 1378 consecutive attenders (response rate 81%) to 10 health centres completed the self-report instruments Impact of Event Scale (IES), and Post Traumatic Symptom Scale (PTSS-10). A horizontal visual analogue scale (VAS; 0-100

BACKGROUND: The method of treatment of aortic valve stenosis in early infancy is still controversial. This study was performed to evaluate short-term and long-term outcome in our center during a 14-year period.METHODS: Between 1991 and 2004, 64 consecutive patients younger than 3 months old underwent open surgical commissurotomy because of aortic valve stenosis. Median age was 18 days (range, 1 to

To examine the influence of phosphorus on the commercial V2O5(WO3)/TiO2 SCR catalyst, measurements were carried out by means of infrared and Raman spectroscopy, XPS, and NO reduction measurement as a function of phosphorus loading. Phosphorus added to the catalyst was found to disperse well over the catalyst without a significant agglomeration up to 5 wt% P2O5 addition. The number of the hydroxyl

PURPOSE: To correlate quantification of collateral flow in aortic coarctation with the morphological visualization of the collateral vessels and to compare different approaches to measurement of collateral flow. MATERIALS AND METHODS: Thirteen children with coarctation were examined with T1-weighted spin-echo (T1-W SE) imaging and 3D contrast-enhanced magnetic resonance angiography (MRA). MR veloc

OBJECTIVE: To study the outcome after acidaemia at term birth, and the relation to gender and duration of pathological fetal heart rate changes. DESIGN: Population based study of 154 infants with umbilical artery pH < 7.05 at term birth. Neonatal outcome and the result of developmental screening at age four years were compared with a control group with pH > 7.10. Fetal heart rate traces in infants

Adenosine triphosphate (ATP), a co-transmitter in sympathetic nerves and released from platelets, has recently been shown to stimulate growth of vascular smooth muscle cells. It might therefore contribute to the development of vascular hypertrophy seen in hypertension and atherosclerosis. We aimed at characterising the receptor mediating this mitogenic effect in rat aorta smooth muscle cells. The
