TL;DR: The localization of COX-2 suggests that this enzyme may be primarily involved in the regulation of renal perfusion and glomerular hemodynamics, and its expression in podocytes of the fetal kidney and its absence in adult glomeruli suggest that this isoform might be involved in glomerulogenesis.
Abstract: To gain insight into the roles of cyclooxygenase (COX)-1 and -2 in human kidney, we analyzed their expressions and localization in adult and fetal normal kidney. Immunohistology showed expression of COX-1 in collecting duct cells, interstitial cells, endothelial cells, and smooth muscle cells of pre- and postglomerular vessels. Expression of COX-2 immunoreactive protein could be localized to endothelial and smooth muscle cells of arteries and veins and intraglomerularly in podocytes. In contrast to the rat, COX isoforms were not detected in the macula densa. These data were confirmed by in situ mRNA analysis using digoxigenin-labeled riboprobes. In fetal kidney, COX-1 was primarily expressed in podocytes and collecting duct cells. Expression levels of COX-1 in both cell types increased markedly from subcapsular to juxtamedullary cortex. Glomerular staining of COX-2 was detectable in podocytes only at the endstage of renal development. In summary, the localization of COX-2 suggests that this enzyme may be primarily involved in the regulation of renal perfusion and glomerular hemodynamics. The expression of COX-1 in podocytes of the fetal kidney and its absence in adult glomeruli suggests that this isoform might be involved in glomerulogenesis.

TL;DR: This is a review of recommendations for diagnostic criteria, differential diagnosis, and guidelines for the evaluation of patients on Proteus syndrome held in March 1998 at the National Institutes of Health.
Abstract: Proteus syndrome is a complex disorder comprising malformations and overgrowth of multiple tissues. The disorder is highly variable and appears to affect patients in a mosaic manner. This intrinsic variability has led to diagnostic confusion associated with a dearth of longitudinal data on the natural history of Proteus syndrome. To clarify some of these issues, a workshop on Proteus syndrome was held in March 1998 at the National Institutes of Health, and participants developed recommendations for diagnostic criteria, differential diagnosis, and guidelines for the evaluation of patients. This is a review of those recommendations.

TL;DR: It is unknown whether differences in the abundances of specific bacterial taxa can be observed in individuals at high risk, for example, with idiopathic rapid eye movement sleep behavior disorder, a prodromal condition of α‐synuclein aggregation disorders including PD.
Abstract: Background
Increasing evidence connects the gut microbiota and the onset and/or phenotype of Parkinson's disease (PD). Differences in the abundances of specific bacterial taxa have been reported in PD patients. It is, however, unknown whether these differences can be observed in individuals at high risk, for example, with idiopathic rapid eye movement sleep behavior disorder, a prodromal condition of α-synuclein aggregation disorders including PD.
Objectives
To compare microbiota in carefully preserved nasal wash and stool samples of subjects with idiopathic rapid eye movement sleep behavior disorder, manifest PD, and healthy individuals.
Methods
Microbiota of flash-frozen stool and nasal wash samples from 76 PD patients, 21 idiopathic rapid eye movement sleep behavior disorder patients, and 78 healthy controls were assessed by 16S and 18S ribosomal RNA amplicon sequencing. Seventy variables, related to demographics, clinical parameters including nonmotor symptoms, and sample processing, were analyzed in relation to microbiome variability and controlled differential analyses were performed.
Results
Differentially abundant gut microbes, such as Akkermansia, were observed in PD, but no strong differences in nasal microbiota. Eighty percent of the differential gut microbes in PD versus healthy controls showed similar trends in idiopathic rapid eye movement sleep behavior disorder, for example, Anaerotruncus and several Bacteroides spp., and correlated with nonmotor symptoms. Metagenomic sequencing of select samples enabled the reconstruction of genomes of so far uncharacterized differentially abundant organisms.
Conclusion
Our study reveals differential abundances of gut microbial taxa in PD and its prodrome idiopathic rapid eye movement sleep behavior disorder in comparison to the healthy controls, and highlights the potential of metagenomics to identify and characterize microbial taxa, which are enriched or depleted in PD and/or idiopathic rapid eye movement sleep behavior disorder. © 2017 The Authors.

TL;DR: Overexpression of NSP1 and infection with live SARS-CoV strongly increased signalling through the Calcineurin/NFAT pathway and enhanced the induction of interleukin 2, compatible with late-stage immunopathogenicity and long-term cytokine dysregulation as observed in severe SARS cases.
Abstract: Coronaviruses (CoVs) are important human and animal pathogens that induce fatal respiratory, gastrointestinal and neurological disease. The outbreak of the severe acute respiratory syndrome (SARS) in 2002/2003 has demonstrated human vulnerability to (Coronavirus) CoV epidemics. Neither vaccines nor therapeutics are available against human and animal CoVs. Knowledge of host cell proteins that take part in pivotal virus-host interactions could define broad-spectrum antiviral targets. In this study, we used a systems biology approach employing a genome-wide yeast-two hybrid interaction screen to identify immunopilins (PPIA, PPIB, PPIH, PPIG, FKBP1A, FKBP1B) as interaction partners of the CoV non-structural protein 1 (Nsp1). These molecules modulate the Calcineurin/NFAT pathway that plays an important role in immune cell activation. Overexpression of NSP1 and infection with live SARS-CoV strongly increased signalling through the Calcineurin/NFAT pathway and enhanced the induction of interleukin 2, compatible with late-stage immunopathogenicity and long-term cytokine dysregulation as observed in severe SARS cases. Conversely, inhibition of cyclophilins by cyclosporine A (CspA) blocked the replication of CoVs of all genera, including SARS-CoV, human CoV-229E and -NL-63, feline CoV, as well as avian infectious bronchitis virus. Non-immunosuppressive derivatives of CspA might serve as broad-range CoV inhibitors applicable against emerging CoVs as well as ubiquitous pathogens of humans and livestock.
