Little is known about the pattern of genetic testing and frequency of genetic diagnoses among children enrolled in structured complex care programs (CCPs). Such information may inform the suitability of emerging genome diagnostics for this population. The objectives were to describe the proportion of children with undiagnosed genetic conditions despite genetic testing and measure the testing period, types and costs of genetic tests used. A retrospective analysis of 420 children enrolled in Toronto's Hospital for Sick Children's CCP from January 2010 until June 2014 was conducted...

INTRODUCTION: Rheumatoid arthritis (RA) is a crippling disease with a global prevalence of approximately 0.5%-1% in adults. Genetic, environmental and immunologic factors contribute importantly to pathogenesis of RA. American College of Rheumatology (ACR) assists in early diagnosis of the disease. AIM: The aim of this study was to investigate the effects of HLA-DRB1 gene and anti-Cyclic Citrullinated Peptide (CCP) antibody on Clinical Disease Activity Index (CDAI) and to determine the frequency of HLA-DRB1 alleles in the patients with RA...

The goal of this study was to investigate the glycosylation profile of native IgG present in serum immune complexes in patients with rheumatoid arthritis (RA). To accomplish this, lectin binding assays, detecting the accessibility of glycans present on IgG-containing immune complexes by biotinylated lectins were employed. Lectins capturing fucosyl residues (AAL), fucosylated tri-mannose N-glycan core sites (LCA), terminal sialic acid residues (SNA) and O-glycosidically-linked galactose/N-acetylgalactosamine (GalNac-L) were used...

Discrimination between different gases is an essential aspect for industrial and environmental applications involving sensing and separation. Several classes of porous materials have been used in this context, including zeolites and more recently MOFs. However, to reach high selectivities for the separation of gas mixtures is a challenging task that often requires the understanding of the specific interactions established between the porous framework and the gases. Here we propose an approach to obtain an enhanced selectivity based on the use of compartmentalized coordination polymers, named CCP-1 and CCP-2, which are crystalline materials comprising isolated discrete cavities...

The Orange Carotenoid Protein (OCP) governs photoprotection in the majority of cyanobacteria. It is structurally and functionally modular, comprised of a C-terminal regulatory domain (CTD), an N-terminal effector domain (NTD) and a ketocarotenoid; the chromophore spans the two domains in the ground state and translocates fully into the NTD upon illumination. Using both the canonical OCP1 from Fremyella diplosiphon and the presumably more primitive OCP2 paralog from the same organism, we show that an NTD-CTD heterodimer forms when the domains are expressed as separate polypeptides...

Carbonic anhydrases (CAs; EC 4.2.1.1) are metalloenzymes with a pivotal potential role in the biomimetic CO2 capture process (CCP) because these biocatalysts catalyse the simple but physiologically crucial reaction of carbon dioxide hydration to bicarbonate and protons in all life kingdoms. The CAs are among the fastest known enzymes, with kcat values of up to 10(6) s(-1) for some members of the superfamily, providing thus advantages when compared with other CCP methods, as they are specific for CO2. Thermostable CAs might be used in CCP technology because of their ability to perform catalysis in operatively hard conditions, typical of the industrial processes...

Understanding the molecular basis of adaptive response to variable environmental conditions is a central goal of evolutionary biology. Here we sought to identify potential outlier SNPs (single nucleotide polymorphisms) in three wild populations of a freshwater prawn (Macrobrachium australiense) that are exposed to differing osmotic niches by using a comparative transcriptomics approach. De novo assembly of approximately 542 million (75 nt) pair end reads collected from 10 individuals revealed 123,396 longer contigs/transcripts of variable length, that showed 97...

Abatacept is a fusion protein (CTLA4-Ig) and therapeutic molecule labeled for the treatment of rheumatoid arthritis (RA). Abatacept acts both by disrupting the CD28-mediated activation of T cells and by interacting with CD80/CD86 molecules present on antigen presenting cells such as monocytes and memory B cells. Accordingly and to evaluate clinical and biological parameters associated with response to abatacept, a retrospective monocentric study was conducted in 43 patients with RA, and the clinical response was evaluated at 6 months according to EULAR response criteria...

Specific human leukocyte antigen (HLA)-DRB1 alleles encode a "shared epitope" (SE) associated with rheumatoid arthritis (RA), especially more severe cyclic-citrullinated peptide antibody-positive (anti-CCP+) RA. Associations of SE alleles (0, 1 or 2) with total and cardiovascular disease (CVD) mortality and incident coronary heart disease (CHD), CVD and malignancy over mean (SD) = 8.9(3.5) years of follow-up were evaluated, stratified by baseline anti-CCP (+ vs. -). The longitudinal Women's Health Initiative (WHI) -RA study (1993-2010), sampled postmenopausal women who reported RA at baseline (1993-1998) or follow-up in WHI, classified as anti-CCP+ RA (n = 556) or anti-CCP- not RA (n = 1,070)...

microRNAs (miRNAs) are derived from self-complementary hairpin structures, while small-interfering RNAs (siRNAs) are derived from double-stranded RNA (dsRNA) or hairpin precursors. The core mechanism of sRNA production involves DICER-like (DCL) in processing the smallRNAs (sRNAs) and ARGONAUTE (AGO) as effectors of silencing, and siRNA biogenesis also involves action of RNA-Dependent RNA Polymerase (RDR), Pol IV and Pol V in biogenesis. Several other proteins interact with the core proteins to guide sRNA biogenesis, action, and turnover...

BACKGROUND: Undifferentiated arthritis (UA) is a label applied to patients with joint complaints which cannot be classified according to current criteria, which implies a need for precision diagnostic technologies. We studied serum galectin-3, a proinflammatory mediator, and seromarkers of structural joint elements in patients with early, UA and their associations with disease profile and biochemical and imaging findings. METHODS: One hundred and eleven UA patients were followed-up for at least 12 months and reclassified according to appropriate criteria (TUDAR)...
