BACKGROUND: Constitutional hypotension (CHT) is defined as a SBP below 105 mmHg. As autonomic-related symptoms are frequently reported in CHT, these symptoms suggest that the cardiovascular autonomic control is perturbed in individuals with CHT. METHODS: We investigated the autonomic cardiovascular control of 15 women with CHT and 12 women with NBP (SBP >110 mmHg). We monitored BP and ECG for autonomic function test. Supine and head up tilt (HUT) spectral analysis of RR interval and BP variability, baroreflex sensitivity and plasma levels of plasma renin activity and aldosterone were determined...

INTRODUCTION: Currently, there is no specific immunosuppressive protocol for hepatitis C (HCV)-positive renal transplants recipients. Thus, the aim of this study was to evaluate the conversion effect to everolimus (EVR) on HCV in adult kidney recipients. METHOD: This is an exploratory single-center, prospective, randomized, open label controlled trial with renal allograft recipients with HCV-positive serology. Participants were randomized for conversion to EVR or maintenance of calcineurin inhibitors...

Although a nationwide activation system has been developed to increase deceased donor kidney transplantation (DDKT), there is still enormous discrepancy between transplant need and deceased donor supply in Korea, and therefore waiting time to DDKT is still long. We need to determine the current status of waiting time and the risk factors for long waiting time. We retrospectively analyzed the medical records of the patients on the wait list for DDKT at the Seoul National University Hospital from 2000 to 2017...

BACKGROUND: Practical application of prospective risk analysis (PRA) in clinical laboratories should reflect processes as they are carried out, while making the PRA results obtained from different processes comparable. This means that not only STAT and standard testing and testing for critical and less critical parameters should be distinguished (as published), but also that the throughput in processes and process steps should be taken into account. METHODS: Building on our previously published PRA, a method was developed to compensate for the throughput in processes and process steps...

BACKGROUND: The aldosterone/renin ratio (ARR) is recommended to screen for primary aldosteronism (PA) in hypertension. We estimated fully automated chemiluminescence immunoassays (CLIA) for plasma aldosterone concentrations (PAC) and plasma direct renin concentrations (PRC) and investigated their reference intervals in Chinese Han population. METHODS: PAC and PRC were measured on a fully automated analyzer (LIAISON XL, DiaSorin, Italy). Performance characteristics were estimated according to CLSI proved guidelines...

The process by which committed precursors mature into cardiomyocytes is poorly understood. We found that TLR3 inhibition blocked cardiomyocyte maturation; precursor cells committed to the cardiomyocyte lineage failed to express maturation genes and sarcomeres did not develop. Using various approaches, we found that the effects of TLR3 upon cardiomyocyte maturation were dependent upon the RelA subunit of nuclear factor kappa B (NFκB). Importantly, under conditions that promote the development of mature cardiomyocytes NFκB became significantly enriched at the promoters of cardiomyocyte maturation genes...

We evaluated the influence of hesperidin and vitamin C (VitC) on glycemic parameters, lipid profile, and DNA damage in male Wistar rats treated with sucrose overload. Rats were divided into six experimental groups: I-water control; II-sucrose control; III-hesperidin control; IV-VitC control; V-co-treatment of sucrose plus hesperidin; VI-co-treatment of sucrose plus VitC. We measured the levels of triglycerides, total cholesterol, HDL-c, LDL-c, fasting glucose, and glycated hemoglobin (A1C). DNA damage was evaluated in blood and brain cells using the comet assay and the micronucleus test was used to evaluate chromosomal damages in the rat bone marrow...

BACKGROUND: Plasma renin is an important regulator of blood pressure (BP). Plasma renin activity (PRA) has been shown to correlate with variability in BP response to antihypertensive agents. We conducted a genome-wide association study to identify single-nucleotide polymorphisms (SNPs) associated with baseline PRA using data from the PEAR study (Pharmacogenomic Evaluation of Antihypertensive Responses). METHODS: Multiple linear regression analysis was performed in 461 whites and 297 blacks using an additive model, adjusting for age, sex, and ancestry-specific principal components...

BACKGROUND: Identifying preoperative risk factors that may portend poorer operative outcomes remains a topic of current interest. In hip and knee arthroplasty patients, the presence of patient-reported allergies (PRAs) has been associated with worse pain and function after joint replacement. However, these results have not been replicated across studies, including in shoulder arthroplasty cases. The impact of PRAs on foot and ankle outcomes has yet to be studied. The purpose of our study was to evaluate whether PRAs influence patient-reported outcome in foot and ankle surgery...

Progressive retinal atrophy (PRA) is a common cause of blindness in many dog breeds. It is most often inherited as a simple Mendelian trait, but great genetic heterogeneity has been demonstrated both within and between breeds. In many breeds the genetic cause of the disease is not known, and until now, the Old Danish Pointing Dog (ODP) has been one of those breeds. ODP is one of the oldest dog breeds in Europe. Seventy years ago the breed almost vanished, but today a population still exists, primarily in Denmark but with some dogs in Germany and Sweden...

Background: Pathogenic variations in HSD11B2 gene triggers the apparent mineralocorticoid excess syndrome (AME). There is scarce information regarding the phenotypes of subjects carrying heterozygous pathogenic variants in HSD11B2 gene. We investigated if serum cortisol/cortisone(F/E) ratio and cortisone are useful for identifying partial 11βHSD2 deficiency in those heterozygous subjects. Methods: We studied two patients diagnosed with AME and their families carrying either D223N or R213C mutation...

The objective was to study the relationship between crystal structure, particle deformation properties and tablet-forming ability for the monoclinic form of paracetamol (PRA), two cocrystals and a salt crystal of PRA in addition to two coformers (oxalic acid and 4,4'-bipyridine). Thus, the structure - property - performance relationship was investigated. Analytical powder compression was used for determination of effective plasticity, as inferred from the Heckel yield pressure and the Frenning parameter, and the elastic deformation was determined from in-die tablet elastic recovery...
