Previous studies have examined the association between elevated serum uric acid (SUA) level and hypertension; however, the association in the Chinese elderly is still uncertain. A cross-sectional study was performed in a rural district of Beijing. A total of 2,397 participants (967 men and 1,430 women) completed the survey. The SUA levels of participants were categorized into four levels using the quartiles (P25, P50, and P75) as cutoff values. Participant was diagnosed as hyperuricemia if the SUA level was ≥417 μmol/L (male) or ≥357 μmol/L (female)...

INTRODUCTION: Deficient 25-hydroxyvitamin D (25(OH)D) levels have been associated with dyslipidemia and cardiovascular diseases, though the underlying mechanism of these associations is uncertain. We analyzed associations between vitamin D and other non-lipid biomarkers of cardiovascular risk to better elucidate possible relationships between deficient 25(OH)D and cardiovascular disease. MATERIAL AND METHODS: We performed a cross-sectional analysis of 4,591 adults included in a clinical laboratory database from 2009 to 2011 with available measurements for 25(OH)D and the following biomarkers: homocysteine (Hcy), high-sensitivity C-reactive protein (hs-CRP), cystatin-C, creatinine, γ-glutamyltransferase (GGT), uric acid, and hemoglobin A1c (HbA1c)...

Tetracarpidium conophorum leaves are used in traditional medicine for the treatment of male infertility, without considering its toxicity and side effects. In this study, we investigated the effects of T conophorum leaves on some biochemical parameters such as alanine aminotransferase, aspartate aminotransferase, bilirubin, albumin, creatinine, and uric acid. Histology of the liver and kidney were also assessed. The result revealed that the alanine aminotransferase and aspartate aminotransferase levels of the control group were not significantly different from the experimental groups...

BACKGROUND: Asians have among the highest prevalence of chronic kidney disease (CKD) or end-stage renal disease in the world. A risk score capable of identifying high risk individuals at the primary care level could allow targeted therapy to prevent future development of CKD. Risk scores for new CKD have been developed in US general populations, but the impact of various risks factors for development of CKD may differ in Asian subjects. In this study, we aimed to develop risk models and simplified risk scores to predict the development of decreased glomerular filtration rate (GFR) at 10 years in an Asian general population using readily obtainable clinical and laboratory parameters...

Knowledge of intracellular metabolite levels is important for the understanding of metabolic flux distributions. Whole-cell biosensors of key metabolites are ideal for the monitoring of carbon flow in important metabolic pathways, thus guiding metabolic engineering for microbial improvement. However, lack of biosensors for metabolites of interests has limited their applications. In this study, a genetically encoded whole-cell biosensor specifically responding to shikimic acid has been developed by screening a site-saturation mutagenesis library of the binding pocket of a uric acid-responsive regulatory protein...

BACKGROUND: Clinical assessment of dehydration in children with acute gastroenteritis (AGE) is crucial for treatment. The gold standard for assessment is acute weight loss. A previous study showed dehydration severity, as determined by weight loss, significantly correlated with serum urea (UN) in children with AGE. However, the limitation of using UN as a marker of dehydration severity is that the level can be affected by nutrition. Serum uric acid (UA) theoretically could serve as an alternative in this regard, but there have been no reports analyzing a direct relationship between serum UA and weight loss...

REVIEW
Tony Merriman
Genome-wide association studies (GWAS) have identified nearly 30 loci associated with urate concentrations that also influence the subsequent risk of gout. The ABCG2 Q141 K variant is highly likely to be causal and results in internalization of ABCG2, which can be rescued by drugs. Three other GWAS loci contain uric acid transporter genes, which are also highly likely to be causal. However identification of causal genes at other urate loci is challenging. Finally, relatively little is known about the genetic control of progression from hyperuricemia to gout...

BACKGROUND: Insulin resistance (IR) is a key factor in diabetes mellitus, metabolic syndrome (MetS) and obesity and may occur in mood disorders and tobacco use disorder (TUD), where disturbances of immune-inflammatory, oxidative and nitrosative stress (IO&NS) pathways are important shared pathophysiological pathways. METHODS: This study aimed to a) examine IR and β-cell function as measured by the homeostasis model assessment of insulin resistance (HOMA-IR) and insulin sensitivity and β cell function (HOMA-B) and glucotoxicity (conceptualized as increased glucose levels versus lowered HOMA-B values) in 74 participants with major depressive disorder (MDD) and bipolar disorder, with and or without MetS and TUD, versus 46 healthy controls, and b) whether IR is associated with IO&NS biomarkers, including nitric oxide metabolites (NOx), lipid hydroperoxides (LOOH), plasma advanced oxidation protein products (AOPP), C-reactive protein (CRP), haptoglobin (Hp) and uric acid...
