In the past 20 years, extraction and quantification of mRNA from urinary sediment has emerged as a novel laboratory technique. The potential application of urinary mRNA quantification to the clinical care of patients with SLE has become an active field of research. However, published studies in this area are limited to small-scale ones. mRNA levels of several of cytokine and transcript factor genes have been found to have the potential for the diagnosis or monitoring of disease activity in patients with lupus nephritis...

Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication...

Confocal microscopy utilizing fluorescent dyes is widely gaining use in the clinical setting as a diagnostic tool. Reflectance confocal microscopy is a method of visualizing tissue specimens without fluorescent dyes while relying on the natural refractile properties of cellular and subcellular structures. We prospectively evaluated 76 CNS lesions with confocal reflectance microscopy (CRM) to determine cellularity, architecture, and morphological characteristics. A neuropathologist found that all cases showed similar histopathological features when compared to matched hematoxylin and eosin-stained sections...

Tachykinins (tachykinin-related peptides, TRPs) are multifunctional neuropeptides that have widespread distribution in the central nervous system (CNS) and in the gastrointestinal tract of many insects, and most have been shown to stimulate contractions of visceral muscles. Invertebrate TRPs carry a characteristic conserved C-terminal pentapeptide (FXGXR-amide) and most of them share some amino acid sequence similarities (approx. 45%) with the vertebrate and mammalian tachykinin family. We have functionally characterized the tachykinins in R...

REVIEW

Mitochondria play a pivotal role in the fatty acid oxidation and have been found to be affected early during the macrovesicular fat accumulation in the hepatocytes. The fatty infiltration is the primary cause of oxidative stress and inflammation in the non-alcoholic fatty liver disease (NAFLD), which can lead to the peroxidation of phospholipids, such as cardiolipin. Oxidative stress-induced damage to mitochondrial DNA can result in the impairment of oxidative phosphorylation and further increases the generation of reactive oxygen species...

BACKGROUND/AIMS: Enterococcal peritonitis in peritoneal dialysis (PD) patients is associated with a high complication rate. The optimal treatment regimen of PD-related enterococcal peritonitis is controversial. The latest international guideline recommends intra-peritoneal (IP) vancomycin. Although ampicillin is often effective for systemic enterococcal infections, they have little in vitro activity when added to common PD solutions. Since oral amoxicillin achieves therapeutic drug level in the peritoneal cavity, we explore the efficacy of oral amoxicillin for enterococcal peritonitis...

Lipid lowering properties of glucagon have been reported. Blocking glucagon signaling leads to rise in plasma LDL levels. Here, we demonstrate the lipid lowering effects of acute dosing with Glp1r/Gcgr dual agonist (DualAG). All the experiments were performed in 25 week-old male diet-induced (60% kCal fat) obese mice. After 2 hrs of fasting, mice were injected subcutaneously with vehicle, liraglutide (25nmol/kg) and DualAG (25nmol/kg). De novo cholesterol and palmitate synthesis was measured by deuterium incorporation method using D2O...

GPR40 agonists are effective antidiabetic agents believed to lower glucose through direct effects on the beta cell to increase glucose stimulated insulin secretion. However, not all GPR40 agonists are the same. Partial agonists lower glucose through direct effects on the pancreas, whereas GPR40 AgoPAMs may incorporate additional therapeutic effects through increases in insulinotrophic incretins secreted by the gut. Here we describe how GPR40 AgoPAMs stimulate both insulin and incretin secretion in vivo over time in diabetic GK rats...

Aims: In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities. We sought to evaluate the prognostic impact of a newly-defined staging classification characterizing the extent of extravalvular (extra-aortic valve) cardiac damage among patients with severe AS undergoing AVR. Methods and results: Patients with severe AS from the PARTNER 2 trials were pooled and classified according to the presence or absence of cardiac damage as detected by echocardiography prior to AVR: no extravalvular cardiac damage (Stage 0), left ventricular damage (Stage 1), left atrial or mitral valve damage (Stage 2), pulmonary vasculature or tricuspid valve damage (Stage 3), or right ventricular damage (Stage 4)...

BACKGROUND: Mitochondrial dysfunction contributes to the pathogenesis of acute kidney injury (AKI). The urinary mitochondrial DNA (mtDNA) level was previously shown to predict renal function recovery in AKI following cardiac surgery. Herein, we determine whether urinary mtDNA is a marker of severity and predictor of recovery in AKI due to other etiologies. METHODS: We recruited 107 AKI patients. The urinary mtDNA level was measured, the severity of AKI was quantified, and patients were followed for 90 days...
