Light-induced immobilization of biomolecules as an attractive alternative to micro-droplet dispensing-based arraying technologies

The present work shows how UV light-induced molecular immobilisation (LIMI) of biomolecules onto thiol reactive surfaces can be used to make biosensors, without the need for traditional microdispensing technologies. Using LIMI, arrays of biomolecules can be created with a high degree of reproducibility. This technology can be used to circumvent the need for often expensive nano/microdispensing tec

The bladder cancer genome; chromosomal changes as prognostic makers, opportunities, and obstacles.

During the past decades, the complexity of the bladder cancer genome has become evident. Early cytogenetic studies identified several patterns of chromosomal changes, particularly the frequent loss of chromosome 9. The cytogenetic approach was replaced by molecular methods, such as comparative genome hybridization (CGH) and loss of heterozygosity (LOH) analyses that describe genomic changes at a m

Universal method for synthesis of artificial gel antibodies by the imprinting approach combined with a unique electrophoresis technique for detection of minute structural differences of proteins, viruses, and cells (bacteria). III: Gel antibodies against cells (bacteria)

Artificial antibodies in the form of gel granules were synthesized from the monomers acrylamide and N,N’-methylenebisacrylamide by the imprinting method in the presence of Echerichia coli bacteria as template. The electrophoretic migration velocities of the gel antibodies (i) saturated with the antigen (Escherichia coli MRE-600), (ii) freed of the antigen, and (iii) resaturated with bacteria, were

From cradle to grave: tracking socioeconomic inequalities in mortality in a cohort of 11 868 men and women born in Uppsala, Sweden, 1915-1929.

Ample evidence has shown that early-life social conditions are associated with mortality later in life. However, little attention has been given to the strength of these effects across specific age intervals from birth to old age. In this paper, we study the effect of the family's socioeconomic position and mother's marital status at birth on all-cause mortality at different age intervals in a Swe

Effect of androgen deprivation therapy on the expression of prostate cancer biomarkers MSMB and MSMB-binding protein CRISP3.

We have investigated the effects of short-term neoadjuvant and long-term androgen deprivation therapies (ADTs) on beta-microseminoprotein (MSMB) and cysteine-rich secretory protein-3 (CRISP3) expression in prostate cancer patients. We also studied if MSMB expression was related to genotype and epigenetic silencing. Using an Affymetrix cDNA microarray analysis, we investigated the expression of MSM

Miniaturisation is mandatory unravelling the human proteome.

An insight into the proteome status of today is presented, covering aspects of market values, new scientific literature sources, new technology initiatives and future developments. The authors give a personal view of the importance and the expected progress of microtechnology in proteome research. The background to some of the fundamental analytical technologies where for example, chromatography h

Abstinence, occasional drinking and binge drinking in middle-aged women. The Women's Health in Lund Area (WHILA) Study.

Although drinking patterns in women have received increased attention, few studies have focused on middle-aged women. Drinking patterns were investigated in a population sample of 513 Swedish women aged 50-59, and analysed in relation to social situation, and mental and physical health. The chi-square test was used to analyse differences in proportions. Variables showing significant differences we

Follow-up of intracranial aneurysms treated with detachable coils: comparison of 3D inflow MRA at 3T and 1.5T and contrast-enhanced MRA at 3T with DSA.

INTRODUCTION: The purpose of this prospective study was to compare 3T and 1.5T magnetic resonance angiography (MRA) with digital subtraction angiography (DSA) for the follow-up of endovascular treated intracranial aneurysms to assess the grade of occlusion. MATERIALS AND METHODS: Thirty-seven patients with 41 aneurysms who had undergone endovascular treatment with detachable coils were included. M

Helicobacter species and common gut bacterial DNA in gallbladder with cholecystitis.

AIM: To analyze the association between Helicobacter spp. and some common gut bacteria in patients with cholecystitis. METHODS: A nested-polymerase chain reaction (PCR), specific to 16S rRNA of Helicobacter spp. was performed on paraffin-embedded gallbladder samples of 100 cholecystitis and 102 control cases. The samples were also analyzed for some common gut bacteria by PCR. Positive samples were

The role of Caveolin-1 in cardiovascular regulation.

Abstract Caveolae are omega-shaped membrane invaginations present in essentially all cell types in the cardiovascular system, and numerous functions have been ascribed to these structures. Caveolae formation depends on caveolins, cholesterol, and PTRF-Cavin (polymerase I and transcript release factor-Cavin). The current review summarizes and critically discusses the cardiovascular phenotypes repor

Proteolysis of human thrombin generates novel host defense peptides.

The coagulation system is characterized by the sequential and highly localized activation of a series of serine proteases, culminating in the conversion of fibrinogen into fibrin, and formation of a fibrin clot. Here we show that C-terminal peptides of thrombin, a key enzyme in the coagulation cascade, constitute a novel class of host defense peptides, released upon proteolysis of thrombin in vitr

Arsenic trioxide is highly cytotoxic to small cell lung carcinoma cells.

Small cell lung carcinoma (SCLC) is an extremely aggressive form of cancer and current treatment protocols are insufficient. SCLC have neuroendocrine characteristics and show phenotypical similarities to the childhood tumor neuroblastoma. As multidrug-resistant neuroblastoma cells are highly sensitive to arsenic trioxide (As2O3) in vitro and in vivo, we here studied the cytotoxic effects of As2O3

Accuracy of typical approximations in classical models of intermolecular polarization

One of the largest limitations of standard molecular-mechanics force fields is the neglect of intermolecular polarization. Several attempts to cure this problem have been made, but the results have not always been fully satisfactory. In this paper, we present a quantitative study of the fundamental approximations that underlie polarization models for classical force fields. The induced charge dens
