Using multiple parallel sequencing on Illumina platform, we identified eight microRNAs that showed significant opposite changes of gene expression in cells of the hormone-sensitive LNCaP prostate cancer cell line and in cells of the hormone-resistant DU-145 cell line, in comparison to the microRNA expression in the normal prostate tissue cells. We found that the insulin-like growth factor 1 receptor (IGF1R) gene is a target of five microRNAs whose expression is increased in LNCaP cells and reduced in DU-145 cells...

A newly developed integrated cell culture reverse transcriptase quantitative PCR (ICC-RTqPCR) method and its applicability in UV disinfection studies is described. This method utilizes a cell culture system coupled with four RTqPCR assays to detect four species of human enterovirus (e.g., Enterovirus A, Enterovirus B, Enterovirus C and Enterovirus D). Evaluation of the RTqPCR assays was conducted with coxsackievirus A10, echovirus 30, poliovirus 1 and enterovirus 70 and resulted in 100% specificity for the tested assays...

BACKGROUND: While naloxone, the overdose reversal medication, has been available for decades, factors associated with its availability through pharmacies remain unclear. Studies suggest that policy and pharmacist beliefs may impact availability. Indiana passed a standing order law for naloxone in 2015 to increase access to naloxone. OBJECTIVE: To identify factors associated with community pharmacy naloxone stocking and dispensing following the enactment of a statewide naloxone standing order...

Five simple, rapid, accurate, and precise spectrophotometric methods are developed for the determination of Silodosin (SLD) in the presence of its acid induced and oxidative induced degradation products. Method A is based on dual wavelength (DW) method; two wavelengths are selected at which the absorbance of the oxidative induced degradation product is the same, so wavelengths 352 and 377 nm are used to determine SLD in the presence of its oxidative induced degradation product. Method B depends on induced dual wavelength theory (IDW), which is based on selecting two wavelengths on the zero-order spectrum of SLD where the difference in absorbance between them for the spectrum of acid induced degradation products is not equal to zero so through multiplying by the equality factor, the absorption difference is made to be zero for the acid induced degradation product while it is still significant for SLD...

Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates have been increasingly reported in different reservoirs. The aims of this study were to investigate the presence of ESBL-producing E. coli in fresh vegetables and to characterise their ESBL gene-carrying plasmids. Among the 245 samples from vegetables investigated during 2011-2013, seven putative ESBL-producing E. coli (salad n = 2, sprouts n = 5) were found. They were subjected to ESBL phenotypic confirmatory tests, detection/sequencing of ESBL genes, antimicrobial susceptibility testing (AST), phylotyping, XbaI-macrorestriction analysis, multilocus sequence typing and transformation...

OBJECTIVES: We aimed to assess patient-related determinants potentially influencing antibiotic use. METHODS: Studies published in MEDLINE until 30/09/2015 were searched. We included: (1) qualitative studies describing patients' self-reported determinants of antibiotic use; (2) quantitative studies on either self-reported or objectively assessed determinants associated with antibiotic use. Whenever possible, reported determinants were categorized as "barriers" or "facilitators" of responsible antibiotic use...

Both CD-1 and C57BL/6 wildtype (C57BL/6-WT) mice show equivalent short-term lung toxicity from exposures to styrene, while long-term tumor responses are greater in CD-1 mice. We analyzed lung gene expression from styrene exposures lasting from 1-day to 2-years in male mice from these two strains, including a Cyp2f2(-/-) knockout (C57BL/6-KO) and a Cyp2F1/2A13/2B6 transgenic mouse (C57BL/6-TG). With short term exposures (1-day to 1-week), CD-1 and C57BL/6-WT mice had thousands of differentially expressed genes (DEGs), consistent with changes in pathways for cell proliferation, cellular lipid metabolism, DNA-replication and inflammation...

BACKGROUND: Basal cell carcinomas are the most common periocular malignant tumor. In advanced periocular basal cell carcinoma, vismodegib is a new treatment option which might potentially avoid surgical eye removal. CASE REPORT: We treated a 76-year-old patient unwilling to consent to surgery with vismodegib for advanced periocular basal cell carcinoma on the left forehead that had already undergone several previous treatments. After initial partial remission, the tumor regrew under ongoing therapy, so that radical surgical excision including orbital exenteration was performed...

Neuroinflammation appears to contribute to neurotoxicity observed with heavy alcohol consumption. To assess whether chronic alcohol results in neuroinflammation we used PET and [11 C]PBR28, a ligand that binds to the 18-kDa translocator protein (TSPO), to compare participants with an alcohol use disorder (AUD: n = 19) with healthy controls (HC: n = 17), and alcohol-dependent (n = 9) with -nondependent rats (n = 10). Because TSPO is implicated in cholesterol's transport for steroidogenesis, we investigated whether plasma cholesterol levels influenced [11 C]PBR28 binding...

Porcine Reproductive and Respiratory Syndrome (PRRS) is an elusive model of host/virus relationship in which disease is determined by virus pathogenicity, pig breed susceptibility and phenotype, microbial infectious pressure and environmental conditions. Successful disease control in PRRS-endemic Countries corresponds to "stability", i.e. a condition with no clinical signs of PRRS in the breeding-herd population and no viremia in weaning-age pigs. The aim of this work was to compare the profile and time-course of humoral and cell-mediated immunity in stable and unstable herds, respectively...

In the highly aluminum-resistant tree Eucalyptus camaldulensis, hydrolyzable tannins are proposed to play a role in internal detoxification of aluminum, which is a major factor inhibiting plant growth on acid soils. To understand and modulate the molecular mechanisms of aluminum detoxification by hydrolyzable tannins, the biosynthetic genes need to be identified. In this study, we identified and characterized genes encoding UDP-glucose:gallate glucosyltransferase, which catalyzes the formation of 1-O-galloyl-β-d-glucose (β-glucogallin), the precursor of hydrolyzable tannins...

While chronic infection with the human hepatitis B virus (HBV) and hepatitis delta virus (HDV) inflict major health burdens worldwide, current therapies cannot cure patients. One possible novel approach is blocking virus entry to prevent the establishment of infection in naïve hepatocytes. As HBV and HDV use identical viral envelope proteins and the same entry mechanisms, such a strategy would target both viruses. Entry inhibitors (e.g. neutralizing antibodies) have been relegated to the limited role of prophylaxis...

In recent years, intriguing hints for the violation of lepton flavor universality (LFU) have been accumulated in semileptonic B decays, both in the charged-current transitions b→cℓ^{-}ν[over ¯]_{ℓ} (i.e., R_{D}, R_{D^{*}}, and R_{J/ψ}) and the neutral-current transitions b→sℓ^{+}ℓ^{-} (i.e., R_{K} and R_{K^{*}}). Hints for LFU violation in R_{D^{(*)}} and R_{J/ψ} point at large deviations from the standard model (SM) in processes involving tau leptons. Moreover, LHCb has reported deviations from the SM expectations in b→sμ^{+}μ^{-} processes as well as in the ratios R_{K} and R_{K^{*}}, which together point at new physics (NP) affecting muons with a high significance...

Although American Indian (AI) women continue to experience cancer at higher rates and have not seen the same decline in cancer prevalence as the general U.S. population, little research examines how interactions with health care providers may influence and exacerbate these health disparities. The purpose of the study was to understand the experiences of AI women who receive cancer treatment, which is integral for eradication of AI cancer disparities among women. A qualitative descriptive methodology was used with a sample of 43 AI women with breast, cervical, colon, and other types of cancer from the Northern Plains region of South Dakota...

We consider the problem of model-based clustering in the presence of many correlated, mixed continuous, and discrete variables, some of which may have missing values. Discrete variables are treated with a latent continuous variable approach, and the Dirichlet process is used to construct a mixture model with an unknown number of components. Variable selection is also performed to identify the variables that are most influential for determining cluster membership. The work is motivated by the need to cluster patients thought to potentially have autism spectrum disorder on the basis of many cognitive and/or behavioral test scores...
