High Throughput Sequencing Identifies Misregulated Genes in the Drosophila Polypyrimidine Tract-Binding Protein (hephaestus) Mutant Defective in Sper…
2015
The Drosophila polypyrimidine tract-binding protein (dmPTB or hephaestus) plays an important role during spermatogenesis. The heph2 mutation in this gene results in a specific defect in spermatogenesis, causing aberrant spermatid individualization and male sterility. However, the array of molecular defects in the mutant remains uncharacterized. Using an unbiased high throughput sequencing approach, we have identified transcripts that are misregulated in this mutant. Aberrant transcripts show altered expression levels, exon skipping, and alternative 5' ends. We independently verified these findings by reverse-transcription and polymerase chain reaction (RT-PCR) analysis. Our analysis shows m…
Circulation and diagnostics of Puumala virus in Norway: nephropatia epidemica incidence and rodent population dynamics.
2017
Hantaviruses pose a public health concern worldwide causing haemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Puumala virus (PUUV) is the most prevalent hantavirus in Central and Northern Europe, and causes a mild form of HFRS, also known as nephropathia epidemica (NE). In nature, the main host of PUUV is the bank vole (Myodes glareolus), and transmission to humans occurs through inhalation of aerosols from rodent excreta. Nephropathia epidemica is particularly prevalent in Nordic countries, however, few studies of PUUV have been performed in Norway. The aim of this study was to analyse the dynamics of PUUV in Norway and compare with bank vole population…
Performance evaluation of gastrointestinal viral ELIte panel multiplex RT-PCR assay for the diagnosis of rotavirus, adenovirus and astrovirus infecti…
2019
Rotavirus, adenovirus, norovirus and astrovirus are considered to be among the major causes of sporadic cases and outbreaks of acute gastroenteritis globally. Rapid and accurate identification of enteric viruses is still a challenge for the clinical laboratory. Recently, several molecular platforms for the detection of viral enteric pathogens have become available. In this study, the diagnostic accuracy of InGenius Gastrointestinal Viral (GV) Elite Panel, a newly developed one-step multiplex real-time RT-PCR assay simultaneously detecting rotavirus, adenovirus and astrovirus, was evaluated retrospectively analyzing an archival collection of 128 stool samples of children hospitalized with ac…
Family meal participation is associated with dietary intake among 12-month-olds in Southern Norway
2021
Abstract Background Family meal participation is associated with healthier eating among children and adolescents. Less is known about family meal participation among infants and toddlers. The objective of the present study was to explore whether family meal participation at 12 months of age is associated with dietary intake and whether a potential relationship differs according to maternal education or child sex. Methods Follow-up data from children born to mothers participating in the Norwegian Fit for Delivery (NFFD) trial during pregnancy were used to assess the frequency of intake of 11 dietary items according to frequency of participating in the respective family meals. Dietary differe…
Simultaneous Inhibition of Peripheral CB1R and iNOS Mitigates Obesity-Related Dyslipidemia Through Distinct Mechanisms.
2020
Diabetic dyslipidemia, characterized by increased plasma triglycerides and decreased HDL cholesterol levels, is a major factor contributing to nonalcoholic steatohepatitis and cardiovascular risk in type 2 diabetes. Activation of the cannabinoid-1 receptor (CB1R) and activation of inducible nitric oxide synthase (iNOS) are associated with nonalcoholic steatohepatitis progression. Here, we tested whether dual-targeting inhibition of hepatic CB1R and iNOS improves diabetic dyslipidemia in mice with diet-induced obesity (DIO mice). DIO mice were treated for 14 days with (S)-MRI-1867, a peripherally restricted hybrid inhibitor of CB1R and iNOS. (R)-MRI-1867, the CB1R-inactive stereoisomer that …
Establishment of two quantitative nested qPCR assays targeting the human EPO transgene.
2016
International audience; For ethical and safety reasons it is critical to develop easily implemented assays with high sensitivity and specificity for gene doping surveillance. Two nested quantitative real-time PCR (qPCR) assays were developed that target the human EPO (hEPO) cDNA sequence in a circular form, representative of recombinant adeno-associated viral (rAAV) vector genomes found in vivo. Through an interlaboratory evaluation, the assays were validated and utilized in an in vitro blinded study. These assays are specific and extremely sensitive with a limit of detection (LOD) of 1 copy of circular plasmid DNA and a limit of quantification (LOQ) of 10 to 20 copies in the presence of 50…
Retrospective Analysis of Checkpoint Inhibitor Therapy-Associated Cases of Bullous Pemphigoid From Six German Dermatology Centers
2021
Immune-related adverse events (irAEs) are a class-effect of checkpoint inhibitors (CIs). The development of a Bullous pemphigoid (BP)-like blistering disease, driven by autoantibodies against the hemidesmosomal protein BP180, is a potentially serious irAE whose incidence seems to be increasing. We therefore set out to characterize the clinical and (immuno)histopathological features and treatment responses of cases of BP which developed during or after CI therapy collated in six German tertiary referral centers between 2014 and 2018. We identified twelve cases of BP which emerged during and/or after CI therapy. The time interval between the initiation of CI therapy and the diagnosis of BP wa…
Verrucous Plaque With Unusually Large Candida Blastoconidia: A Unique Clinicopathological Presentation of Systemic Mucocutaneous Candidiasis.
2018
Mucocutaneous candidiasis is a common infection affecting both immunocompetent and immunosuppressed individuals. Diversity in the clinical and histopathological presentation of mucocutaneous candidiasis is well known. However, the occurrence of cutaneous verrucous lesions and giant yeast-like structures has been rarely reported. In this article, we describe a case of disseminated mucocutaneous candidiasis in an immunosuppressed patient who presented as a verrucous plaque on the scrotum with giant Candida blastoconidia. This peculiar presentation expands the clinicopathological spectrum of mucocutaneous candidiasis and highlights the wide range of clinical manifestations and great morphologi…
Performance evaluation of a newly developed molecular assay for the accurate diagnosis of gastroenteritis associated with norovirus of genogroup II
2018
The performance of a newly proposed fully automated cassette-based sample-to-results solution for norovirus (NoV) detection, InGenius Norovirus ELITe MGB®, was evaluated. A total of 120 selected archival stool samples from children hospitalized for acute gastroenteritis were used to compare the results to a reference real-time RT-PCR. The InGenius NoV assay showed optimal diagnostic accuracy (sensitivity, 100%; specificity, 95.7%) and was able to correctly detect the entire wide panel of epidemiologically relevant genotypes tested. These preliminary results suggest that the InGenius NoV assay can be recommended as a valuable method for accurate diagnosis of NoV GII infection in epidemic and…
Infant Formula Feeding Increases Hepatic Cholesterol 7α Hydroxylase (CYP7A1) Expression and Fecal Bile Acid Loss in Neonatal Piglets.
2018
BACKGROUND: During the postnatal feeding period, formula-fed infants have higher cholesterol synthesis rates and lower circulating cholesterol concentrations than their breastfed counterparts. Although this disparity has been attributed to the uniformly low dietary cholesterol content of typical infant formulas, little is known of the underlying mechanisms associated with this altered cholesterol metabolism phenotype. OBJECTIVE: We aimed to determine the molecular etiology of diet-associated changes in early-life cholesterol metabolism with the use of a postnatal piglet feeding model. METHODS: Two-day-old male and female White-Dutch Landrace piglets were fed either sow milk (Sow group) or d…
