BACKGROUND: Parechoviruses (HPeV) are endemic seasonal pathogens detected from the respiratory tract, gut, blood and central nervous system (CNS) of children and adults, sometimes in conjunction with a range of acute illnesses. HPeV CNS infection may lead to neurodevelopmental sequelae, especially following infection by HPeV-3, hence screening and genotyping are important to inform epidemiology, aetiology and prognosis. OBJECTIVES: To identify and characterise HPeVs circulating during an outbreak between November 2013 and April 2014 in Queensland, Australia...

Rapid diagnosis of respiratory infections is of great importance for adequate isolation and treatment. Due to the batch-wise testing, laboratory-developed real-time polymerase chain reaction (PCR) assays (LDT) often result in a time to result of one day. Here, LDT was compared with rapid ePlex® Respiratory Pathogen (RP) Panel testing of GenMark Diagnostics (Carlsbad, CA, USA) with regard to time to result, installed isolation precautions, and antibacterial/antiviral treatment. Between January and March 2017, 68 specimens of 64 patients suspected of an acute respiratory infection were tested with LDT and the ePlex® RP panel...

Subtle molecular differences indicate the heterogeneity present in a number of disease settings. Digital-PCR (dPCR) platforms achieve the necessary levels of sensitivity and accuracy over standard quantitative RT-PCR (qPCR) that promote their use for such situations, detecting low abundance transcript and subtle changes from gene expression. An underlying requisite is good quality RNA, principally dictated by appropriate tissue handling and RNA extraction. Here we consider the application of dPCR to measures of gene expression in pathological tissues with inherent necrosis, focusing on rheumatoid subcutaneous nodules...

Insulin degrading enzyme (IDE) is believed to act as a junction point of type 2 diabetes (T2D) and Alzheimer's disease (AD), however, the underlying mechanism was not completely clear yet. Transgenic APPSwe/PS1 mice were used as the AD model and were treated with streptozocin/streptozotocin (STZ) to develop a mixed mice model presenting both AD and T2D. Morris Water Maze (MWM) and recognition task were performed to trace the cognitive function. The detection of fasting plasma glucose (FPG) and plasma insulin concentration, and Oral Glucose Tolerance Test (OGTT) were used to trace the metabolism evolution...

Ovarian cancer (OC) is one of the most lethal cancers among all gynecological malignancies. An effective and non-invasive screening approach is needed urgently to reduce high mortality rate. The purpose of this study was to identify the salivary protein signatures (SPS) for non-invasive detection of ovarian cancer. Differentially expressed SPS were identified by fluorescence-based 2D-DIGE coupled with MALDI/TOF-MS. The expression levels of three differential proteins (Lipocalin-2, indoleamine-2, 3-dioxygenase1 (IDO1) and S100A8) were validated using western blotting and ELISA...

C-C chemokine receptor type 5 (CCR5) is a chemokine receptor that influences the immune response to infectious and parasitic diseases. This study aimed to determine whether the CCR5Δ32 and CCR5 59029 A/G polymorphisms are associated with the development of ocular toxoplasmosis in humans. Patients with positive serology for Toxoplasma gondii were analyzed and grouped as 'with ocular toxoplasmosis' (G1: n=160) or 'without ocular toxoplasmosis' (G2: n=160). A control group (G3) consisted of 160 individuals with negative serology...

Leishmania infantum is a protozoan that causes visceral leishmaniasis, a potentially deadly neglected tropical disease. The gold standard for diagnosis has traditionally been detection of amastigotes in bone marrow or spleen aspirates, but this is an invasive procedure that carries the risk of serious complications. Newer PCR techniques are opening new avenues and tissues for testing. Therefore, we tested if amastigotes and DNA from L. infantum could be detected in patient urine. We detected L. infantum DNA in six out of 30 urine samples from patients with visceral leishmaniasis and the promastigotes were isolated in culture from the urine of one patient...

The use of engineered nucleases combined with a homologous DNA donor template can result in targeted gene correction of the sickle cell disease mutation in hematopoietic stem and progenitor cells. However, because of the high homology between the adjacent human β- and δ-globin genes, off-target cleavage is observed at δ-globin when using some endonucleases targeted to the sickle mutation in β-globin. Introduction of multiple double-stranded breaks by endonucleases has the potential to induce intergenic alterations...

The role of a 32 base pair deletion in the CCR5 gene (CCR5Δ32) in HIV-disease progression and response to combined antiretroviral therapy (cART) is well established. However, the impact of CCR5Δ32 in the long-term survival pre-cART and after cART introduction in a large cohort of HIV-infected patients is unknown. We analyzed the association of CCR5Δ32 deletion in the long-term survival of HIV-infected patients recruited between June 1981 and October 2016 (n = 1006). Clinical and epidemiological variables were recorded and CCR5Δ32 deletion was assessed by PCR and electrophoretic analysis...

microRNAs (miRNAs) have been reported to play crucial roles in malignant tumor progression, including cell development, proliferation, and progression. Increasing evidence suggests that miR-495 functions as either an oncogene or tumor suppressor in several tumor types. However, its biological role in the development of colorectal cancer (CRC) still remains unclear. In this study, we found that miR-495 expression level was remarkably down-regulated in CRC tissues samples and cell lines when compared to adjacent normal tissues and cell line by using qRT-PCR detection...
