During a medical entomology course in Boa Vista, Roraima, colonies of Triatoma maculata closely associated with pigeon nests were observed in concrete air-conditioner box located on the external plastered and cemented walls of a modern brick-built apartment block. In only one eight-hole ceramic brick, located inside one air-conditioner box, 127 specimens of T. maculata were collected. T. maculata is a recognised vector of Trypanosoma cruzi in the surrounding area and its domiciliation increases the risk of Chagas disease transmission...

Adult T-cell leukemia/lymphoma (ATLL) is a rare and often aggressive lymphoid malignancy known to be associated with human T-cell lymphotropic virus type 1. There are 2 broad categories: acute and chronic. In the acute category, there is a leukemic and a lymphomatous variant, whereas in the designated "chronic" form, there is mild peripheral blood lymphocytosis. The intermediate "smoldering" category is without peripheral blood lymphocytosis with only discernible skin involvement. We present a 68-year-old human T-cell lymphotropic virus type 1 seropositive female with a mild peripheral blood atypical lymphocytosis who had indurated nodules on her hands of 2 years duration and a new scaly ichthyosiform eruption on her lower extremities...

Fragments of small nucleolar RNAs (snoRNAs) were found among various non-coding RNAs (ncRNAs) circulating in human blood. Currently, the function of such cell-free sno-derived-RNAs is not clearly defined. This work is aimed at identifying regulatory pathways controlled by extracellular snoRNAs. In order to determine the molecular targets and pathways affected by artificial snoRNAs, we performed Illumina array analysis of MCF-7 human adenocarcinoma cells transfected with box C/D RNAs. The genes related to the innate immune response and apoptotic cascades were found to be activated in transfected cells compared with control cells...

Neuralized Homology Repeats (NHRs) were first identified in Neuralized, an E3-ubiquitin ligase that plays a key role in the Notch signalling pathway. Since their original discovery, NHR domains have been shown to regulate protein-protein interactions in a broad range of developmental processes and in a wide variety of species from flies to humans. The NHR family of proteins can be categorized into three groups: (1) those that contain a RING finger, (2) those that contain a SOCS box and, (3) those that only have NHR domains...

Potatoes are one of the commodities with the highest loss shares along the entire supply chain. In the present study, we analyzed six potential loss reduction scenarios concerning their environmental-socio-economic sustainability compared with the current situation by using the "SustainOS" methodology. For this purpose, life cycle assessments, full-cost calculations and an online consumer survey were conducted. Environmental improvements through loss reduction were rather small and did not cross limits of significance, but the socio-economic performance of the entire supply chain can be improved considerably...

BACKGROUND: Sequence specific polyamide HxIP 1, targeted to the inverted CCAAT Box 2 (ICB2) on the topoisomerase IIα (topo IIα) promoter can inhibit NF-Y binding, re-induce gene expression and increase sensitivity to etoposide. To enhance biological activity, diamino-containing derivatives (HxI*P 2 and HxIP* 3) were synthesised incorporating an alkyl amino group at the N1-heterocyclic position of the imidazole/pyrrole. METHODS: DNase I footprinting was used to evaluate DNA binding of the diamino Hx-polyamides, and their ability to disrupt the NF-Y:ICB2 interaction assessed using EMSAs...

Handover communication improvement initiatives typically employ a "one size fits all" approach. A human factors perspective has the potential to guide how to tailor interventions to roles, levels of experience, settings, and types of patients. We conducted ethnographic observations of sign-outs by attending and resident physicians in 2 medical intensive care units at one institution. Digitally audiotaped data were manually analyzed for content using codes and time spent using box plots for emergent categories...

Hepatocellular carcinoma (HCC) remains one of the most common types of cancer worldwide and prognosis remains poor. Previous studies have suggested that long non‑coding RNAs (lncRNAs) may be key regulators of tumor development and progression in HCC. It has been determined that 61‑72% of transcribed regions contain lncRNAs in the antisense orientation (aslncRNAs). However, the function of aslncRNAs in HCC remains to be elucidated. The present study investigated the function of the aslncRNA zinc finger E‑box binding homeobox 2 antisense RNA 1 (ZEB2‑AS1) in 40 HCC tissues and 5 different human HCC cell lines using reverse transcription‑quantitative polymerase chain reaction...

Prostate carcinoma is a devastating disease which is characterized by insidious early symptoms, rapid progression and a poor prognosis. Tripartite motif-containing protein 16 (TRIM16) was identified as an estrogen- and antiestrogen-regulated gene in epithelial cells stably expressing estrogen receptors. The protein encoded by this gene contains two B-box domains and a coiled-coiled region that are characteristic of the B-box zinc finger protein family. Proteins belonging to this family have been reported to be involved in a variety of biological processes including cell growth, differentiation and pathogenesis...

BACKGROUND & OBJECTIVES: The PAX5, a paired box transcription factor and B-cell activator protein (BSAP), activates B-cell commitment genes and represses non-B-cell lineage genes. About 14 transcript variants of PAX5 have been observed in human. Any alteration in its expression pattern leads to lymphogenesis or associated diseases and carcinogenesis in non-lymphoid tissues. Its mechanisms of function in pathophysiology of non-Hodgkin's lymphoma (NHL) are unclear. This study was intended to explore influence of PAX5 in cascade of NHL pathogenesis and diagnosis...

BACKGROUND: In 2013, the Amateur International Boxing Association (AIBA) introduced a rule banning headgear for male-senior open class boxers during competition. The AIBA has defended the rule change as motivated by safety and supported by internal unpublished studies. As a result, in 2018, the AIBA plans to universally prohibit headgear in competition: for all competitors (male and female), all ages and all levels. Within Canada, this ruling has generated controversy in the boxing community, yet there has been no overall measure of opinion...

In bacteria, chromosome replication is initiated by the interaction of the initiator protein DnaA with a defined region of a chromosome at which DNA replication starts (oriC). While DnaA proteins share significant homology regardless of phylogeny, oriC regions exhibit more variable structures. The general architecture of oriCs is universal, i.e., they are composed of a cluster of DnaA binding sites, a DNA-unwinding element, and sequences that bind regulatory proteins. However, detailed structures of oriCs are shared by related species while being significantly different in unrelated bacteria...

BACKGROUND: In cognitive neuroscience the potential of Deep Neural Networks (DNNs) for solving complex classification tasks is yet to be fully exploited. The most limiting factor is that DNNs as notorious 'black boxes' do not provide insight into neurophysiological phenomena underlying a decision. Layer-wise Relevance Propagation (LRP) has been introduced as a novel method to explain individual network decisions. NEW METHOD: We propose the application of DNNs with LRP for the first time for EEG data analysis...

GATA transcription factors regulate an array of genes important in cell proliferation and differentiation. Here we report the identification of regulator of G protein signaling 4 (RGS4) as a novel target for GATA-6 transcription factor. Although three sites (a, b, c) within the proximal region of rabbit RGS4 promoter for GATA transcription factors were predicted by bioinformatics analysis, only GATA-a site (16 bp from the core TATA box) is essential for RGS4 transcriptional regulation. RT-PCR analysis demonstrated that only GATA-6 was highly expressed in rabbit colonic smooth muscle cells but GATA-4/6 were expressed in cardiac myocytes and GATA-1/2/3 expressed in blood cells...
