Human adenovirus infects terminally differentiated cells and to replicate it must induce S-phase. The chief architects that drive adenovirus-infected cells into S-phase are the E1A proteins, with 5 different isoforms expressed during infection. E1A remodels the infected cell by associating with cellular factors and modulating their activity. The C-terminus of E1A is known to bind to only a handful of proteins. We have identified a novel E1A C-terminus binding protein, Ku70 (XRCC6), which was found to bind directly within the CR4 of E1A from human adenovirus type 5...

The toxoplasma ICT IgG-IgM rapid diagnostic test for the simultaneous detection of specific toxoplasmic immunoglobulin (Ig) G and IgM was compared with the Architect fully automated chemiluminescence test. Four hundred sera were included, among which 248 scored negative in Architect. The cassettes were easily read with the naked eye. Diagnostic sensitivity and specificity were 97% and 96%, respectively. The test scored 8 false-positive IgG and yielded negative results in 3 sera displaying unspecific IgM in Architect...

A maternal Toxoplasma gondii infection during pregnancy is a risk for congenital infection through maternal-fetal transplacental transmission. Estimation of the date of infection is of the utmost importance for management and treatment recommendations. In this setting, IgG avidity has been shown to be useful as high avidity rules out an infection dating less than 4 months. The estimated date of infection can also be obtained by the ratio of T. gondii IgG titers measured by the Vidas (bioMérieux) assay versus T...

BACKGROUND: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor caused by a malignant transformation in the parafollicular C-cells of the thyroid, where calcitonin (CT) is released. Nowadays the main tumor markers (TM) used in the diagnosis and follow-up of MTC patients are CT and carcinoembryonic antigen (CEA). Nonetheless, progastrin releasing peptide (proGRP) has been recently proposed as a TM useful in the MTC. Our aims were to investigate the release of proGRP in thyroid tumors, its role in the assessment of advanced MTC and its utility in the differential diagnosis between MTC and non-MTC thyroid tumors...

BACKGROUND: Periostin is being investigated as a potential biomarker for T-helper-2 (Th2)-driven asthma or eosinophilic inflammation and may help to identify patients more likely to benefit from interleukin-13-targeted treatments. We report the development and analytic performance of the investigational use only Architect Periostin Immunoassay, a new automated assay developed to detect serum periostin concentrations. METHODS: We assessed assay performance in terms of precision, sensitivity, linearity, interference from classical immunoassay interferents and representatives of common asthma medications, specimen handling, and isoform reactivity...

Toxoplasmosis, a benign infection, is asymptomatic or pauci-symptomatic in over 80% of cases, excepting immunocompetent patients suffering from ocular toxoplasmosis, as well as immunocompromised patients with opportunistic or congenital toxoplasmosis. Diagnosis is mainly based on serology testing. We thus compared the performance of the nine most commonly-used commercial automated or semi-automated immunoassays for IgG and IgM T. gondii antibody detection: Advia Centaur®, Architect®, AxSYM®, Elecsys®, Enzygnost®, Liaison®, Platelia®, VIDAS®, and VIDIA® assays...

BACKGROUND: Syphilis testing conventionally relies on a combination of non-treponemal and treponemal tests. The primary objective of this study was to describe the positive predictive value (PPV) of a screening algorithm in a combination of a treponemal rapid diagnostic test (RDT) and rapid plasma reagin (RPR) test at Komfo Anokye Teaching Hospital (KATH), Ghana. MATERIALS AND METHODS: From February 2014 to January 2015, 5 mL of venous blood samples were taken from 16 016 blood donors and tested with a treponemal RDT; 5 mL of venous blood was taken from 526 consenting initial syphilis sero-reactive blood donors...

BACKGROUND: Diabetes-induced oxidative stress and hypertension play a major role in the development of nephropathy. Hence, the present study was undertaken to evaluate the protective effects of molsidomine, a nitric oxide donor in streptozotocin (STZ)-induced diabetic nephropathy (DN) in rats. MATERIALS AND METHODS: Type 1 diabetes was induced through a single dose of STZ (52 mg/kg, i.p.) in male Wistar rats and then treated with molsidomine (5 and 10 mg/kg; p.o...

The coefficient of thermal expansion (CTE) of architected materials, as opposed to that of conventional solids, can be tuned to zero by intentionally altering the geometry of their structural layout. Existing material architectures, however, achieve CTE tunability only with a sacrifice in structural efficiency, i.e. a drop in both their stiffness to mass ratio and strength to mass ratio. In this work, we elucidate how to resolve the trade-off between CTE tunability and structural efficiency and present a lightweight bi-material architecture that not only is stiffer and stronger than other 3D architected materials, but also has a highly tunable CTE...

Though only one component product of the larger eugenics movement, the eugenic family study proved to be, by far, its most potent ideological tool. The Kallikak Family, for instance, went through eight editions between 1913 and 1931. This essay argues that the current scholarship has missed important ways that the architects of the eugenic family studies theorized and described the subjects of their investigation. Using one sparsely interrogated work (sociologist Frank Wilson Blackmar's "The Smoky Pilgrims") and one previously unknown eugenic family study (biologist Frank Gary Brooks' untitled analysis of the flood-zone Oklahomans) from the Southern Plains, this essay aims to introduce "environment" as a schema that allows for how the subjects of the eugenic family study were conceptualized with respect to their surroundings...

Integrins are cell surface receptors that bind cells to their physical external environment, linking the extracellular matrix to cell function. They are essential in the biology of all animals. In the late 1980s, we discovered that integrins are required for the ability of breast epithelia to do what they are programmed to do, which is to differentiate and make milk. Since then, integrins have been shown to control most other aspects of phenotype: to stay alive, to divide, and to move about. Integrins also provide part of the mechanism that allows cells to form tissues...

Behaviour models are the most commonly used input for predicting the reliability of a software system at the early design stage. A component behaviour model reveals the structure and behaviour of the component during the execution of system-level functionalities. There are various challenges related to component reliability prediction at the early design stage based on behaviour models. For example, most of the current reliability techniques do not provide fine-grained sequential behaviour models of individual components and fail to consider the loop entry and exit points in the reliability computation...

Soft materials featuring both 3D free-form architectures and high stretchability are highly desirable for a number of engineering applications ranging from cushion modulators, soft robots to stretchable electronics; however, both the manufacturing and fundamental mechanics are largely elusive. Here, we overcome the manufacturing difficulties and report a class of mechanical metamaterials that not only features 3D free-form lattice architectures but also poses ultrahigh reversible stretchability (strain > 414%), 4 times higher than that of the existing counterparts with the similar complexity of 3D architectures...

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive form of cancer and the therapeutic outcome for T-ALL patients remains poor. Thus innovative therapeutic strategies with less toxic drugs are of immense need. Moreover combinational effect of redox imbalance with modulated EGFR/PI3K/Akt axis in T-ALL is still elusive. To explore more effective drugs we developed and characterized 5-SMAG, Cu-5-SMAG and Cu-OBPHA complexes by different spectroscopic methods and revealed that introduction of methoxy group and copper to the previously synthesized Schiff base ligand, NG can efficiently target leukemia by sparing the normal cells and overcomes MDR in T-ALL through induction of caspase3 dependent apoptosis as assessed by MTT, Cell-cycle, Annexin-V and caspase3 activation assay...

CONTEXT: The short ACTH stimulation test (250 μg) is the dynamic test most frequently used to assess adrenal function. It is possible that a single basal cortisol could be used to predict the dynamic response, but research has been hampered by the use of different assays and thresholds. OBJECTIVE: To propose a morning baseline cortisol criterion of three of the most commonly used modern cortisol immunoassays - Advia Centaur (Siemens), Architect (Abbott) and the Roche Modular System (Roche) - that could predict adrenal sufficiency...

The aim of this article is to demonstrate how women of color feminism predates and disrupts dominant dialogues in the field of White affect studies. I introduce the concept of White affect studies as an arena of inquiry that draws from Western-European theories and literatures and architects a sociopolitical structure of affect that positions White affects as universal. Scholars contributing to the field of White affect studies posit theories of affect, embodiment, subjectivity, phenomenology, violence, war, and more, while disregarding the theoretical contributions made by women of color feminism in thinking through these notions and social issues...
