Background: Monoclonal antibodies (mAb) are important tools in the management of tumor disease, and the discovery of antibodies with both specific cancer cell targeting and capacity to enter the cells by internalization are critical to improve the therapeutic efficacy. Method: Antibody cancer cell targeting and internalization properties of fluoroscein-conjugated mAb made against Lewis Y (BR96) we

Pollen dispersal between local plant populations within a range of 6 kin in a geographically defined metapopulation of the lepidopteran-pollinated deceptive orchid Anacamptis pyramidalis was studied on the island Oland in the Baltic Sea. Local A. pyramidalis populations were examined for pollinators, flowering individuals, and fruit set. Population sizes of pollen vector species were estimated usi

BACKGROUND: Albers-Schonberg disease, or autosomal dominant osteopetrosis type II (ADO2), is caused by ineffective osteoclastic bone resorption resulting from mutations in the chloride channel 7 (ClCN7) gene. Individuals with ADO2 have increased numbers of large ineffective osteoclasts in addition to increased serum total tartrate-resistant acid phosphatase (TRACP) activity. METHODS: We investigat

Temporin A (TA) is a hydrophobic peptide isolated from the skin of the European red frog Rana temporaria. Strong antimicrobial activity against gram-positive cocci and Candida, as well as its small molecular weight (10-13 aa residues), makes TA an interesting antimicrobial compound. However, its synthesis is rather problematic. Here, the synthesis of two retro-analogues of TA--retro-TA and (6-1)(7

Using the Cayley–Hamilton theorem and unique solubility of scalar Volterra convolution equations of the second kind, the inverse problem of determining the four time-dependent susceptibility dyadics of a linear, homogeneous, bi-anisotropic slab from generic scattering data at oblique incidence is shown to be well posed. An explicit formula for the crucial step is given.

Three-dimensional (3-D) ultrasound (US) has greatly improved evaluation of organ circulation. The aim of this study was to explore the possible use of this new technique in normal and high-risk pregnancies. Fetal brain, lung and placenta 3-D power Doppler signal intensity were recorded in 115 normal singleton pregnancies (24 to 42 weeks gestation) and in 67 high-risk pregnancies. Mean image pixel

With the recent expansions of the European Union, there are now 12 new member states that are implementing European policy. One of these policies, with implications for energy production and security, is the Common Agricultural Policy. This article will focus on the impact the Common Agricultural Policy can have on farmers in Poland who have been encouraged by calls to cultivate energy crops. In a

OBJECTIVE: To assess the risk of over-diagnosing and over-treating prostate cancer if population-based screening with serum prostate-specific antigen (PSA) is instituted. PATIENTS AND METHODS: From a serum bank stored in 1980, PSA was analysed in 658 men with no previously known prostate cancer from a well-defined cohort from Goteborg, Sweden (men born in 1913); the incidence of clinical prostate

A general model for through drying of tissue was developed based on the equations of continuity in combination with correlations for heat and mass transfer. The model incorporates different geometric descriptions together with corresponding heat and mass transfer correlations for flow through cylindrical conduits and flow through packed beds of cylindrical fibers. At low intensities, i.e., at low

A particle image velocimetry (PIV) method has been developed to measure the velocity field inside and around a forming drop with a final diameter of 1 mm. The system, including a microscope, was used to image silicon oil drops forming in a continuous phase of water and glycerol. Fluorescent particles with a diameter of 1 μm were used as seeding particles. The oil was forced through a 200 μm diamet

Objectives: To explore the effect of social characteristics of residential areas on carotid atherosclerosis prevalence. Methods and results: The associations among area social characteristics and B-mode ultrasound determined carotid plaque-score (a semi-quantitative scale measuring the degree of atherosclerosis in the carotid bifurcation area) were cross-sectionally investigated in a general popul

Partial hemitransection was performed through a knife lesion at the meso-diencephalic level in rats to sever the mesostriatal dopamine system. During the subsequent 2 weeks the animals received 0.125 mg/kg/h of nicotine continuously via an osmotic minipump implanted s.c. To achieve prompt high nicotine levels, 4 i.p. injections of 0.5 mg/kg nicotine were, in addition, given during the first 2 h fo

Abstract The yeast Saccharomyces kluyveri (Lachancea kluyveri), a far relative of Saccharomyces cerevisiae, is not a widely studied organism in the laboratory. However, significant contributions to the understanding of nucleic acid precursors degradation in eukaryotes have been made using this model organism. Here we review eukaryotic pyrimidine degradation with emphasis on the contributions made

Background Empirical data about end-of-life decision-making practices are scarce. We aimed to investigate frequency and characteristics of end-of-life decision-making practices in six European countries: Belgium, Denmark, Italy, the Netherlands, Sweden, and Switzerland. Methods In all participating countries, deaths reported to death registries were stratified for cause (apart from in Switzerland)

GRACILE syndrome (growth retardation, aminoaciduria, cholestasis, iron overload, lactacidosis, and early death; OMIM 603358) is a rare metabolic disorder with autosomal recessive mode of inheritance. So far it has been diagnosed only in patients with Finnish ancestors. The GRACILE locus has been positioned to a restricted region of chromosome 2q33-37, but the causative gene remains to be identifie

This paper argues for the relevance of the media history of the press. Using a broad and open media concept, this perspective should be understood as the study of the construction and communication of the self-images and ideology of the press. Rather than describing the complex of problems as images that are ‘spread’ through one channel (newspapers) by one actor (the press), it should be seen as a

When describing isokinetic effects by the model of selective energy transfer by resonance, it is sometimes found that the frequency of the forcing oscillator is quite different to that of the reacting molecule, i.e."resonance" is not a very good concept to use. By noting that the two frequencies thus found are related to each other as the ratios of small integers, e.g. 4:3, this dilemma is resolve

Atomic processes like e.g. molecular vibrations, chemical reactions or phase transitions happen on picosecond down to femtosecond time scales. Novel pulsed X-ray sources or alternatively ultrafast X-ray detectors allow the investigation of these processes in real time. A powerful tool for the investigation of the dynamics in crystalline materials is time resolved X-ray diffraction (TRXD). As an ex
