Formation of epiblast (EPI) - the founder line of all embryonic lineages - and extra-embryonic supportive tissues is one of the key events in mammalian development. The prevailing model of early mammalian development is based almost exclusively on the mouse. Here we provide a comprehensive, stage-by-stage analysis of the EPI and extraembryonic primitive endoderm (PrE) formation during pre-implantation development of the rabbit. Whilst we observed that rabbit embryos have several features in common with mouse embryos, including a stage-related initiation of lineage specification, our results demonstrate the existence of some key differences in lineage specification among mammals...

The association between glomerular hyperfiltration and cardiovascular events is not well known. To investigate whether glomerular hyperfiltration is independently associated with risk of adverse outcome we analyzed 8794 participants, average age 52 years enrolled in 8 prospective studies. Of these, 89% had hypertension. Using the 5th and 95th percentiles of the age- and sex-specific quintiles of CKD-EPI-calculated estimated glomerular filtration rate (eGFR), we identified three participant groups with low, high and normal eGFR...

BACKGROUND: Underweight is a well-known complication of chronic pancreatitis (CP), but little is known about its prevalence in the outpatient setting. We investigated the prevalence of underweight in outpatients with CP and its association with quality of life (QOL) and various risk factors. METHODS: This was a cross-sectional study of 166 outpatients with CP that was conducted at a tertiary referral center. The primary outcome was the prevalence of underweight (body mass index [BMI] <20 kg/m(2)) in patients with CP compared with 160 age- and sex-matched controls...

BACKGROUND/OBJECTIVES: Exocrine pancreatic insufficiency (EPI) is an important complication of chronic pancreatitis (CP). Guidelines recommend to rule out EPI in CP, to detect those patients who would benefit from pancreatic enzyme replacement therapy. The aim of this study was to evaluate the prevalence of EPI in patients with CP without follow-up in the last 2 years and to describe their nutritional status and quality of life (QoL). METHODS: This was a cross-sectional, multicenter Spanish study...

Calculating the estimated glomerular filtration rate (eGFR) using creatinine-based equations may underestimate cardiovascular risk. Cystatin C-based eGFR may be a stronger prognostic biomarker than creatinine-based eGFR when assessing cardiovascular outcomes and mortality. Our aim was to determine whether levels of serum cystatin C, as an estimator of GFR, had a higher predictive value than creatinine-based eGFR for incident cardiovascular disease among hypertensive patients. We retrospectively analyzed the records of 2016 hypertensive patients from the Hypertension Unit at Mostoles University Hospital between 2006 and 2016...

Since 2011, the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) has typically been notified of three or fewer cases of hepatitis A virus (HAV) infection each year among men who have sex with men (MSM) who reported no travel to countries where HAV is endemic. This year, DOHMH noted an increase in HAV infections among MSM with onsets in January-March 2017, and notified other public health jurisdictions via Epi-X, CDC's communication exchange network. As a result, 51 patients with HAV infection involving MSM were linked to the increase in NYC...

In this report, originally proposed apratoxin E (30S-7), revised apratoxin E (30R-7), and (30S)/(30R)-oxoapratoxin E (30S)-38/(30R)-38 were efficiently prepared by two synthetic methods. The chiral lactone 10, recycled from the degradation of saponin glycosides, was utilized to prepare the key non-peptide fragment 9. Our alternative convergent assembly strategy was applied to the divergent synthesis of revised apratoxin E and its three analogs. Moreover, ring-closing metathesis (RCM) was first time found to be an efficient strategy for the macrocyclization of apratoxins...

OBJECTIVE: Signal drop-off occurs in echo-planar imaging in inferior brain areas due to field gradients from susceptibility differences between air and tissue. Tailored-RF pulses based on a hyperbolic secant (HS) have been shown to partially recover signal at 3 T, but have not been tested at higher fields. MATERIALS AND METHODS: The aim of this study was to compare the performance of an optimized tailored-RF gradient-echo echo-planar imaging (TRF GRE-EPI) sequence with standard GRE-EPI at 7 T, in a passive viewing of faces or objects fMRI paradigm in healthy subjects...

Alpha TC1 (αTC1) and Beta-TC-6 (βTC6) mouse islet cell lines are cellular models of islet (dys)function and type 2 diabetes (T2D). However, genomic characteristics of these cells, and their similarities to primary islet alpha and beta cells, are undefined. Here, we report the epigenomic (ATAC-seq) and transcriptomic (RNA-seq) landscapes of αTC1 and βTC6 cells. Each cell type exhibits hallmarks of its primary islet cell counterpart including cell-specific expression of beta (e.g., Pdx1) and alpha (e.g., Arx) cell transcription factors (TFs), and enrichment of binding motifs for these TFs in αTC1/βTC6 cis-regulatory elements...

Background International Society of Nephrology/ Renal Pathology Society (ISN/RPS) consensus on the classification of lupus nephritis (LN) subdivided class IV into diffuse segmental (IV-S) and diffuse global (IV-G). Nephrologists and nephropathologists believe that this subclassification would be clinically relevant based on hypothetical distinct immunopathogenesis of those subclasses guiding therapy as well as judging prognosis. Methods All adult patients with a renal biopsy-confirmed diagnosis of LN class IV undergoing regular follow-up in the Nephrology Division between January 2004 and December 2014 were enrolled excluding those with diabetes, hepatitis B, hepatitis C, HIV as well as those with insufficient clinical and hystopathological data...
