Wnt-5a-induced phosphorylation of DARPP-32 inhibits breast cancer cell migration in a CREB-dependent manner.

Tumour cell migration plays a central role in the process of cancer metastasis. We recently identified dopamine and cAMP regulated phospho-protein of 32 kDa (DARPP-32) as an anti-migratory phospho-protein in breast cancer cells. Here we link this effect of DARPP-32 to Wnt-5a signalling by demonstrating that recombinant Wnt-5a triggers cAMP elevation at the plasma membrane and Thr34-DARPP-32 phosph

Genetic bottlenecks and the hazardous game of population reduction in cell line based research.

Established tumour cell lines are ubiquitous tools in research, but their representativity is often debated. One possible caveat is that many cell lines are derived from cells with genomic instability, potentially leading to genotype changes in vitro. We applied SNP-array analysis to an established tumour cell line (WiT49). Even though WiT49 exhibited chromosome segregation errors in 30% of cell d

An Architecture for Integrated Test Data Compression and Abort-on-Fail Testing in a Multi-Site Environment

The semiconductor technology development makes it possible to fabricate increasingly advanced integrated circuits (ICs). However, because of imperfections at manufacturing, each individual IC must be tested. A major problem at IC manufacturing test is the increasing test data volume as it leads to high automatic test equipment (ATE) memory requirement, long test application time and low throughput

Acceptance of HIV testing among women attending antenatal care in south-western Uganda: risk factors and reasons for test refusal.

A problem commonly encountered in programs for prevention of mother-to-child-transmission (PMTCT) of HIV in sub-Saharan Africa is low rates of HIV test acceptance among pregnant women. In this study, we examined risk factors and reasons for HIV test refusal among 432 women attending three antenatal care clinics offering PMTCT in urban and semi-urban parts of the Mbarara district, Uganda. Structure

Rapid cortical reorganisation and improved sensitivity of the hand following cutaneous anaesthesia of the forearm.

The cortical representation of various body parts constantly changes based on the pattern of afferent nerve impulses. As peripheral nerve injury results in a cortical and subcortical reorganisation this has been suggested as one explanation for the poor clinical outcome seen after peripheral nerve repair in humans. Cutaneous anaesthesia of the forearm in healthy subjects and in patients with nerve

A revised Swedish version of the Ward Atmosphere Scale: Usability and psychometrics.

Background: The ward atmosphere of psychiatric care units has a major impact on treatment and satisfaction for both patients and staff. The Ward Atmosphere Scale (WAS) was developed to capture the ward atmosphere in different psychiatric settings and is a well-established instrument for this purpose. However, there is need for an update and revision of the WAS. Aim: The aim of the present study wa

EuroQol-5 dimensions utility gain according to British and Swedish preference sets in rheumatoid arthritis treated with abatacept, rituximab, tocilizumab, or tumour necrosis factor inhibitors: a prospective cohort study from southern Sweden.

The development of EuroQol-5 dimensions (EQ-5D) utility over time in rheumatoid arthritis (RA) patients, treated with biologics other than tumour necrosis factor inhibitors (TNFi), based on the standard British (UK) and the new Swedish (SE) EQ-5D preference sets, has not been previously described.

Blood-brain barrier permeability and nerve cell damage in rat brain 14 and 28 days after exposure to microwaves from GSM mobile phones.

We investigated the effects of global system for mobile communication (GSM) microwave exposure on the permeability of the blood-brain barrier and signs of neuronal damage in rats using a real GSM programmable mobile phone in the 900 MHz band. Ninety-six non-anaesthetized rats were either exposed to microwaves or sham exposed in TEM-cells for 2 h at specific absorption rates of average whole-body S

P2 receptors in cardiovascular regulation and disease.

The role of ATP as an extracellular signalling molecule is now well established and evidence is accumulating that ATP and other nucleotides (ADP, UTP and UDP) play important roles in cardiovascular physiology and pathophysiology, acting via P2X (ion channel) and P2Y (G protein-coupled) receptors. In this article we consider the dual role of ATP in regulation of vascular tone, released as a cotrans

Antibiotic prophylaxis in urological surgery, a European viewpoint.

Surgical site infections (SSI) including urinary tract infections (UTI) cause a significant morbidity in urological surgery. Antibiotic prophylaxis is one of several factors impacting on infection rates. Antibiotic prophylaxis is relevant only for clean and clean-contaminated operations and in the absence of bacterial growth in the urine. Strict classification of urological procedures is lacking,

Ubiquitin chain cleavage: CYLD at work.

The tumor suppressor CYLD is a deubiquitylating enzyme that negatively regulates different signaling pathways by removing lysine 63-linked polyubiquitin chains from several specific substrates. In various tumor types, CYLD loss can lead to cell survival or cell proliferation. In addition to its loss due to mutations, CYLD expression can also be decreased through transcriptional and post-transcript

Dermatan Sulfate Epimerase 1-Deficient Mice have Reduced Content and Changed Distribution of Iduronic acids in Dermatan Sulfate and an Altered Collagen Structure in Skin.

Dermatan sulfate epimerase 1 (DS-epi1) and 2 convert glucuronic acid to iduronic acid in chondroitin/dermatan sulfate biosynthesis. Here we report on the generation of DS-epi1-null mice and the resulting alterations in the chondroitin/dermatan polysaccharide chains. The numbers of long blocks of adjacent iduronic acids are greatly decreased in skin decorin and biglycan chondroitin/dermatan sulfate

Reducing delirium in elderly patients with hip fracture: a multi-factorial intervention study.

Background: There is an evident need for improved management of elderly patients with trauma in order to avoid common and troublesome complications such as delirium. The aim of this study was to investigate whether an implementation of a multi-factorial program including intensified pre-hospital and perioperative treatment and care could reduce the incidence of delirium in elderly patients with hi

The Short-Term Results of 3 Common UKA Implants During Different Periods in Sweden.

We studied 13299 operations of 3 common unicompartmental implants inserted during 1984 to 2004 and compared their cumulative revision rate during different periods, as well as whether minimally invasive surgery (MIS) had been used. In this way, we tried to evaluate how the introduction of implants and approaches affected the short-term results. The oldest implant, the Link, had stable results over

CYP2C8 and CYP2C9 polymorphisms in relation to tumour characteristics and early breast cancer related events among 652 breast cancer patients.

BACKGROUND: CYP2C8/9 polymorphisms may influence breast cancer-free survival after diagnosis due to their role in the metabolism of tamoxifen, paclitaxel, and other chemotherapy. cytochrome P450 (CYP)2C8/9 metabolise arachidonic acid to epoxyeicosatrienoic acids, which enhance migration and invasion in vitro and promote angiogenesis in vivo. We aimed to investigate the frequency of CYP2C8/9 polymo
