Cell-free microRNAs (miRNAs) are transferred in disease state including inflammatory lung diseases and are often packed into extracellular vesicles (EVs). To assess their suitability as biomarkers for community-acquired pneumonia (CAP) and severe secondary complications such as sepsis, we studied patients with CAP (n = 30), sepsis (n = 65) and healthy volunteers (n = 47) subdivided into a training (n = 67) and a validation (n = 75) cohort. After precipitating crude EVs from sera, associated small RNA was profiled by next-generation sequencing (NGS) and evaluated in multivariate analyses. A subset of the thereby identified biomarker candidates was validated both technically and additionally by reverse transcription quantitative real-time PCR (RT-qPCR). Differential gene expression (DGE) analysis revealed 29 differentially expressed miRNAs in CAP patients when compared to volunteers, and 25 miRNAs in patients with CAP, compared to those with sepsis. Sparse partial-least discriminant analysis separated groups based on 12 miRNAs. Three miRNAs proved as a significant biomarker signature. While expression levels of miR-1246 showed significant changes with an increase in overall disease severity from volunteers to CAP and to sepsis, miR-193a-5p and miR-542-3p differentiated patients with an infectious disease (CAP or sepsis) from volunteers. Cell-free miRNAs are potentially novel biomarkers for CAP and may help to identify patients at risk for progress to sepsis, facilitating early intervention and treatment.

To provide a chronological overview of the evolution of continent urinary diversion (CUD) over the last 50years and to highlight important milestones.

We performed an extensive literature review and analysed different forms of urinary diversion worldwide. After the evaluation of surgical techniques, we assessed the advantages and disadvantages of assorted CUD approaches based on published long-term follow-up data.

A wide variety of surgical options for CUD is available and feasible to date, although consensus among urologists regarding the 'gold standard' is still lacking. read more Several forms of orthotopic bladder substitutes and continent cutaneous urinary reservoirs have been shown to provide excellent long-term results.

The last 50years of CUD have seen constant evolution and refinement of techniques, but the best surgical approach remains unclear and there is no 'one-size-fits-all' option, but rather tailor-made approaches are necessary to ensure patient satisfaction.

So far, thousands of circRNAs have been discovered in eukaryotic cells. CircRNAs are more stable due to its resistance to exonuclease implying important biological functions in all kingdoms of life. They could function as miRNA sponges, interfere with splicing and bind to protein to regulate the expression of host genes and so on. In addition, emerging evidence suggests that circRNAs are closely related to a series of physiological processes in livestock and poultry. In this review, we summarized the biogenesis mechanism, major biological function and detection methods and focused on research advance of circRNAs in livestock and poultry, aiming at providing certain reference value and novel techniques for the development of new molecular genetic markers and breeding of livestock and poultry. Meanwhile, we hope this review could show significant prospect for other researches.

Astatine-211 (At-211) is a promising alpha emitter for radionuclide therapy. High-resolution in vivo imaging of At-211 in small animals is needed for the development of At-211 radiopharmaceuticals. For this purpose, we developed a low-energy x-ray camera using a thin YAlO

Ce (YAP(Ce)) plate to image the low-energy x rays (73-87keV) from the daughter radionuclide of At-211 (Po-211).

We optically coupled a 38×38×1-mm YAP (Ce) plate to a position-sensitive photomultiplier (PSPMT) to develop an imaging detector. A pinhole or a parallel hole collimator was attached to the imaging detector, and the performance was measured for 60-keV gamma photons. With the developed x-ray camera, we carried out imaging of a mouse that had been administered At-211-NaAt.

The intrinsic spatial resolution of the YAP (Ce) x-ray camera was approximately 1.2mm FWHM, and the energy resolution was 22% FWHM. With a 5-mm-thick parallel hole collimator, the spatial resolution was 3.8mm FWHM with a sensitivity of 8×10

at 10mm, which is a typical distance from the surface of the collimator to a subject in mouse imaging. Using a 1-mm diameter pinhole collimator, the spatial resolution was 1.8mm FWHM with a sensitivity of 3.5×10

at 10mm from the collimator. In the mouse images measured by the developed x-ray camera, we could clearly observe that the At-211 accumulated in the thyroid gland and the stomach of the mouse.

We concluded that the YAP (Ce) x-ray camera is useful forin vivo imaging of At-211.

We concluded that the YAP (Ce) x-ray camera is useful for in vivo imaging of At-211.The revolution in genetic technology has ushered in a new age for our understanding of the underlying causes of neurodevelopmental, neuromuscular and neurodegenerative disorders, revealing that the presynaptic machinery governing synaptic vesicle fusion is compromised in many of these neurological disorders. This builds upon decades of research showing that disturbance to neurotransmitter release via toxins can cause acute neurological dysfunction. In this review, we focus on disorders of synaptic vesicle fusion caused either by toxic insult to the presynapse or alterations to genes encoding the key proteins that control and regulate fusion the SNARE proteins (synaptobrevin, syntaxin-1 and SNAP-25), Munc18, Munc13, synaptotagmin, complexin, CSPα, α-synuclein, PRRT2 and tomosyn. We discuss the roles of these proteins and the cellular and molecular mechanisms underpinning neurological deficits in these disorders.
