Methods: NHERF1 expression was evaluated by immunohistochemistry in 167 patients with CRC primary tumors, 37 patients with no disease, and 27 patients with metastatic CRC (mCRC); and in the orthotopically implanted tumors in mice.

An Open Platform for Seamless Sensor Support in Healthcare for the Internet of Things.

Population aging and increasing pressure on health systems are two issues that demand solutions. Involving and empowering citizens as active managers of their health represents a desirable shift from the current culture mainly focused on treatment of disease, to one also focused on continuous health management and well-being. Current developments in technological areas such as the Internet of Things (IoT), lead to new technological solutions that can aid this shift in the healthcare sector.

Ezrin expression and cell survival regulation in colorectal cancer.

Colorectal cancer (CRC) is the second largest cause of cancer deaths in the United States. A key barrier that prevents better outcomes for this type of cancer as well as other solid tumors is the lack of effective therapies against the metastatic disease. Thus there is an urgent need to fill this gap in cancer therapy.

In vivo analysis of insulin-like growth factor type 1 receptor humanized monoclonal antibody MK-0646 and small molecule kinase inhibitor OSI-906 in colorectal cancer.

The development and characterization of effective anticancer drugs against colorectal cancer (CRC) is of urgent need since it is the second most common cause of cancer death. The study was designed to evaluate the effects of two IGF-1R antagonists, MK-0646, a recombinant fully humanized monoclonal antibody and OSI-906, a small molecule tyrosine kinase inhibitor on CRC cells. Xenograft study was performed on IGF-1R-dependent CRC cell lines for analyzing the antitumor activity of MK-0646 and OSI-906.

Barriers and facilitators to the implementation of clinical practice guidelines: a cross-sectional survey among physicians in Estonia.

Background: In an era when an increasing amount of clinical information is available to health care professionals, the effective implementation of clinical practice guidelines requires the development of strategies to facilitate the use of these guidelines. The objective of this study was to assess attitudes towards clinical practice guidelines, as well as the barriers and facilitators to their use, among Estonian physicians. The study was conducted to inform the revision of the clinical practice guideline development process and can provide inspiration to other countries considering the increasing use of evidence-based medicine.

The updated clinical guideline development process in Estonia is an efficient method for developing evidence-based guidelines.

Clinical practice guidelines are one of the tools available to improve the quality of health care. However, it may be difficult for countries to develop their own national guidelines "from scratch" because of limitations in time, expertise, and financial resources. The Estonian Health Insurance Fund (EHIF), in collaboration with other stakeholders, has launched a national effort to develop and implement evidence-based clinical practice guidelines aimed at improving the quality of care.

Heating of indoor dust causes reduction in its ability to stimulate release of IL-8 and TNFalpha in vitro compared to non-heated dust.

Unlabelled: Dust is a major contaminant of the indoor air environment and may affect human health. Indoor dust accumulates on surfaces including heaters and light fixtures, and will be heated when these devices are used. Heat treatment of the dust may change its biologic properties and in this study we simulated the heat treatment with a dust-heating model (50-250 degrees C).

Emissions from indoor dust inhibit proliferation of A549 cells and TNFalpha release from stimulated PBMCs.

Dust accumulating on hot indoor surfaces, e.g., heaters and light fixtures, are likely to emit chemicals when heated.

A screening assessment of emissions of volatile organic compounds and particles from heated indoor dust samples.

This paper characterizes and compares emissions during heating of different dust samples relevant to the indoor environment. Characterization includes emission of volatile organic compounds when dust samples were heated to 150 and 250 degrees C (gas chromatograph-mass spectrometer), weight loss during heating to 450 degrees C (thermogravimetric analysis), and the number of particles emitted during heating towards 200 degrees C (condensation nucleus counting). Element analyses were performed for non-heated dust (inductively coupled plasma discharge instrument).

Ribozyme termination of RNA transcripts down-regulate seed fatty acid genes in transgenic soybean.

We investigated whether termination of transcripts with a self-cleaving ribozyme can enhance nuclear retention and serve as a tool to decrease specific plant gene expression. Nuclear retention was first monitored in tobacco using the beta-glucuronidase gene terminated with either the 35S CaMV 3' untranslated sequence (UTR) or a cis-acting ribozyme. Northern blot analysis of nuclear RNA and total RNA, and in situ hybridizations showed that the ribozyme-terminated transcripts were preferentially retained in the nucleus of transgenic tobacco.

Emissions from heated indoor dust.

Settled indoor dust was collected from a university building, and the fine fraction was heated in the temperature range of 50-250 degrees C. Emissions of compounds were analysed and identified in a system consisting of a thermal desorption unit coupled to a gas chromatograph-mass spectrometer (GC-MS). The heating took place in both an oxidative (air) and an inert (He) atmosphere.

Nonsymbiotic hemoglobins in rice are synthesized during germination and in differentiating cell types.

Nonsymbiotic hemoglobins (ns-Hbs) previously have been found in monocots and dicots; however, very little is known about the tissue and cell type localization as well as the physiological function(s) of these oxygen-binding proteins. We report the immunodetection and immunolocalization of ns-Hbs in rice (Oryza sativa L.) by Western blotting and in situ confocal laser scanning techniques.

Prevalence of Brachyspira species isolated from diarrhoeic pigs in Brazil.

Pathogenic intestinal spirochaetes of pigs include Brachyspira (formerly Serpulina) hyodysenteriae, the cause of swine dysentery, and Brachyspira pilosicoli, the cause of porcine colonic spirochetosis (PCS). The purpose of this study was to assess the relative importance of Brachyspira species in diarrhoeal disease of growing pigs on farms in southern Brazil. The intensity and pattern of haemolysis, the production of indole and the hydrolysis of hippurate by reference and field porcine intestinal spirochaetes were compared with 16S-ribosomal RNA (mRNA)- and 23S-rRNA-based polymerase chain reaction assays for the identification of B hyodysenteriae and B pilosicoli.

Elimination of methoxyacetic acid and ethoxyacetic acid in rat.

1. The pharmacokinetics of methoxyacetic acid (MAA) and ethoxyacetic acid (EAA) have been determined in the male and female rat following bolus intravenous administration at 100 mg/kg. The plasma-concentration data of MAA fitted well to a one-compartment model, and the plasma-concentration data of EAA to a two-compartment model.

Peptide-based OspC enzyme-linked immunosorbent assay for serodiagnosis of Lyme borreliosis.

Sera from 210 patients with Lyme borreliosis (LB) were studied by an enzyme-linked immunosorbent assay (ELISA) based on a synthetic peptide (pepC10) comprising the C-terminal 10-amino-acid residues of OspC of Borrelia burgdorferi. We found that 36.3 and 45.

In vitro activity of four antimicrobial agents against North American isolates of porcine Serpulina pilosicoli.

Porcine colonic spirochetosis is a nonfatal diarrheal disease that affects pigs during the growing and finishing stages of production. The disease is caused by Serpulina pilosicoli, a newly recognized species of pathogenic intestinal spirochete. Antimicrobial therapy aimed at reducing the infection may be helpful in controlling spirochetal diarrhea.

The dominant epitope of Borrelia garinii outer surface protein C recognized by sera from patients with neuroborreliosis has a surface-exposed conserved structural motif.

Epitope mapping of outer surface protein C (OspC) by using sera from patients with neuroborreliosis led to the identification of one single major immunodominant epitope within the C-terminal 10 amino acid residues. Peptide binding studies and alanine replacement scanning of the C-terminal decapeptide, PVVAESPKKP, revealed a critical role for the PKKP sequence and its terminal carboxyl group for the binding of immunoglobulin M (IgM) antibodies from patients with Lyme borreliosis. Electron microscopy of antibody-labeled spirochetes indicated that the C-terminal region is exposed on the surface of the spirochete.

Canine intestinal spirochetes consist of Serpulina pilosicoli and a newly identified group provisionally designated "Serpulina canis" sp. nov.

The spirochetes inhabiting the large intestines of humans and animals consist of a diverse group of related organisms. Intestinal spirochetosis caused by Serpulina pilosicoli is a newly recognized enteric disease of human beings and animals with potential public health significance. The purpose of this study was to determine the species identity of canine intestinal spirochetes by comparing 30 isolates obtained from dogs in Australia (n = 25) and the United States (n = 5) with reference strains representing Serpulina species and Brachyspira aalborgi, by phenotypic and genetically based typing methods.

Cecal spirochetosis associated with Serpulina pilosicoli in captive juvenile ring-necked pheasants.

Spirochetes similar to those described in the ceca of broilers with diarrhea and in laying hens with decreased egg production and growth were identified in the ceca of captive-raised juvenile ring-necked pheasants (Phasianus colchicus). The birds were submitted for diagnostic investigation of an illness characterized by a seromucoid ocular discharge, sneezing, swollen infraorbital sinuses, and weight loss. In addition to cecal spirochetosis, the birds had mild enteric coccidiosis, trichomoniasis, and nematodiasis (Heterakis spp.
