BACKGROUND: Asthma is a chronic respiratory disease without a cure, though there exists spontaneous remission. Genome wide association(GWA) studies have pinpointed genes associated with asthma development, but did not investigate asthma remission. OBJECTIVES: We performed a GWA study to develop insights in asthma remission. METHODS: Clinical remission (ClinR) was defined by absence of asthma treatment and wheezing in the last year and asthma attacks in the last 3 years, and complete remission (ComR) similarly but additionally with normal lung function and absence of bronchial hyperresponsiveness (BHR)...

BACKGROUND: Alcohol use disorders (AUDs) are influenced by complex interactions between the genetics of the individual and their environment. We have previously identified hundreds of polygenic genetic variants between the selectively bred high and low alcohol drinking (HAD and LAD) rat lines. Here we report allele specific expression (ASE) differences, between the HAD2 and LAD2 rat lines. METHODS: The HAD2 and LAD2 rats which have been sequenced were reciprocally crossed to generate 10 litters of F1 progeny...

The effect of utilizing a pure cis -α-dimethoxy carbonyl fulleropyrrolidine C70 (DMEC70 ) isomer as the electron transporting material (ETM) in inverted perovskite solar cells (PSCs) was evaluated. The as-prepared C70 mono-adduct products are mixtures of regioisomers and the interest was to evaluate them independently as ETMs. Three different cis -DMEC70 isomers (α, β- endo and β- exo ) (mix-DMEC70 ) were synthesized and purified by HPLC. It was found that PSCs based on the pure α-DMEC70 exhibit a substantially enhanced maximum power conversion efficiency (PCE) of 18...

Rice, a staple food crop, is often subjected to drought and salinity stresses thereby limiting its yield potential. Since there is a cross talk between these abiotic stresses, identification of common and/or overlapping regulatory elements is pivotal for generating rice cultivars that showed tolerance towards them. Analysis of the gene interaction network (GIN) facilitates identifying the role of individual genes and their interactions with others that constitute important molecular determinants in sensing and signaling cascade governing drought and/or salinity stresses...

Widespread mRNA 3' UTR shortening through alternative polyadenylation 1 promotes tumor growth in vivo 2 . A prevailing hypothesis is that it induces proto-oncogene expression in cis through escaping microRNA-mediated repression. Here we report a surprising enrichment of 3'UTR shortening among transcripts that are predicted to act as competing-endogenous RNAs (ceRNAs) for tumor-suppressor genes. Our model-based analysis of the trans effect of 3' UTR shortening (MAT3UTR) reveals a significant role in altering ceRNA expression...

(+)-Cyclazosin [(+)-1] is one of most selective antagonists of the α1B -adrenoceptor subtype (selectivity ratios, α1B /α1A  = 13, α1B /α1D  = 38-39). To improve the selectivity, we synthesized and pharmacologically studied the blocking activity against α1 -adrenoceptors of several homochiral analogues of (+)-cyclazosin featuring different substituents on the carbonyl or amine groups, namely (-)-2, (+)-3, (-)-4-(-)-8, (+)-9. Moreover, we studied the activity of some their opposite enantiomers, namely (-)-1, (-)-3, (+)-6, and (-)-9, to evaluate the influence of stereochemistry on selectivity...

In this paper, we present an attractive method for the fabrication of long, straight, highly crystalline ultra-thin platinum nanowires. The fabrication is simply achieved using an inverse hexagonal (HII) lyotropic liquid crystal phase of the commercial surfactant phytantriol as a template. A platinum precursor dissolved within the cylindrical aqueous channels of the liquid crystal phase is chemically reduced by galvanic displacement using stainless steel. We demonstrate the production of nanowires using the HII phase in the phytantriol/water system which we obtain either by heating to 55 °C, or at room temperature by the addition of a hydrophobic liquid, 9-cis-tricosene, to relieve packing frustration...

Cochlear implants (CIs) often work very well for many children and adults with profound sensorineural (SNHL) hearing loss. Unfortunately, while many CI patients display substantial benefits in recognizing speech and understanding spoken language following cochlear implantation, a large number of patients achieve poor outcomes. Understanding and explaining the reasons for poor outcomes following implantation is a very challenging research problem that has received little attention despite the pressing clinical significance...

Objective: Neurocognitive functions, specifically verbal working memory (WM), contribute to speech recognition in postlingual adults with cochlear implants (CIs) and normal-hearing (NH) listener shearing degraded speech. Three hypotheses were tested: (1) WM accuracy as assessed using three visual span measures - digits, objects, and symbols - would correlate with recognition scores for spectrally degraded speech (through a CI or when noise-vocoded); (2) WM accuracy would be best for digit span, intermediate for object span, and lowest for symbol span, due to the increasing cognitive demands across these tasks...
