Digital telecommunication technology has expanded the potential of the mobile phone to be used increasingly as a weapon against authoritarian rule and censorship. Since the content of mobile communication is unpredictable and unregulated, mobile phones have the capability to breach state-sponsored blockage of information. This in turn helps the Chinese people to maintain contact with each other, r
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
The levels of care in the Swedish healthcare system comprise self-care, primary care as well as accident and emergency care. The Swedish system of specialist ambulance nurses enables referral by prehospital triage. However, little is known about patients' experiences of not being triaged to the emergency department.
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
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
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
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
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
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.
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
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
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,
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 (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
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
