Article Abstract
is a flagellated protozoan parasite in the family that causes an enteric disease of turkeys and ducks known as cochlosomosis. Following the withdrawal of effective antiprotozoal medications from commercial poultry production, this organism has become of increased concern for the turkey industry. Historically, this organism has been detected by light microscopic evaluation of enteric mucosal scrapings. However, live trophozoites must be present in the sample for this method of detection because the parasite is differentiated from other protozoa by its characteristic movement. There is currently no real-time PCR (rtPCR) assay published for this organism; thus, we designed and validated a rtPCR assay. Ten-fold serial dilutions of gBlocks DNA representing the targeted region of the organism were evaluated to determine the limit of detection of the organism, which was ~50 copies per reaction. The assay was specific for , with no cross-detection of 3 other poultry flagellates: , , and . Sensitivity and specificity compared to microscopic detection of live organisms were 100%. Coinfections of with other pathogens have been reported. Thus, this assay can be added to syndromic panels for detection of enteric pathogens of turkeys.

Background And Aims: Gestational diabetes mellitus (GDM) is defined as glucose intolerance first identified during pregnancy that does not meet the criteria for overt diabetes. Its pathophysiology shares key features with type 2 diabetes mellitus (T2D), including insulin resistance and inflammation. Emerging evidence suggests that long non-coding RNAs (lncRNAs) are implicated in T2D.

Background: The chaperoning system, which is responsible for protein homeostasis, plays a significant role in cardiovascular diseases. Among molecular chaperones or heat shock proteins (HSPs), the HSP40 family, the main co-chaperone of HSP70, remains largely underexplored, especially in ischemic heart disease (IHD) risk.
Materials And Results: We genotyped 834 IHD patients and 1,328 healthy controls for three SNPs (rs2034598 and rs7189628 DNAJA2 and rs4926222 DNAJB1) using probe-based real-time PCR.
Myopathology and Immune Profile of Granulomatous Myositis in Sarcoid Myopathy.

Aims: Sarcoid myopathy (SaM) is characterised by granulomatous myositis (GM) and can overlap with inclusion body myositis (IBM), a late-onset chronic idiopathic inflammatory myopathy with a still enigmatic pathogenesis. As GM can occur in different clinical contexts, we aimed to examine the histomorphologic features and gene expression profiles in cases of definite SaM that may inform diagnostic and therapeutic considerations.
Methods: We performed a multidimensional characterisation of muscle biopsy specimens from patients with 'pure SaM' (n=17), SaM with concomitant IBM (SaM-IBM) (n=2), including histopathologic and ultrastructural analysis in addition to quantitative real-time polymerase chain reaction.

The effect of non-functionalized polystyrene nanoparticles (PS-NPs) with diameters of 29, 44, and 72 nm on plasmid DNA integrity and the expression of genes involved in the architecture of chromatin was investigated in human peripheral blood mononuclear cells (PBMCs). The cells were incubated with PS-NPs at concentrations ranging from 0.001 to 100 µg/mL for 24 hours.

Porcine reproductive and respiratory syndrome virus (PRRSV) is an RNA virus that induces reproductive disorders in sows and respiratory diseases in growing pigs. Recently, the NADC34-like strain of PRRSV has become more prevalent, with outbreaks occurring across pig farms in China. However, a reliable diagnostic method for the clinical detection of this strain has been absent.
