Elevated serum uric acid is associated with hypertension and chronic kidney disease. We evaluated the relationship between birthweight and uric acid in a nationally representative sample of 5390 US adolescents aged 12-15 in the National Health and Nutrition Examination Survey from 1999 to 2012. There was an inverse association between birthweight and uric acid after adjustment for sex, age, race, obesity, and dietary sodium intake. Each 1 kg increase in birthweight was associated with decreased uric acid by 0...

Persistent hyperglycaemia coupled with inflammation plays an important role in the pathogenesis of diabetic nephropathy (DN). Present study examined the therapeutic potential of taraxerol isolated from the methanol extract of Abroma augusta leaf against DN using rodent model of type 2 diabetes (T2D). T2D was experimentally induced by high fat diet and a single low-single dose of streptozotocin (35mg/kg, i.p.). Accumulation of serum creatinine, urea, and uric acid, activation of lactate dehydrogenase and creatinin kinase, and release of urinary albumin represented the glomerular damage and the progression of nephropathy in T2D rats...

Biomarker research in Parkinson's disease (PD) has long been dominated by measuring dopamine metabolites or alpha-synuclein in cerebrospinal fluid. However, these markers do not allow early detection, precise prognosis or monitoring of disease progression. Moreover, PD is now considered a multifactorial disease, which requires a more precise diagnosis and personalized medication to obtain optimal outcome. In recent years, advanced metabolite profiling of body fluids like serum/plasma, CSF or urine, known as "metabolomics", has become a powerful and promising tool to identify novel biomarkers or "metabolic fingerprints" characteristic for PD at various stages of disease...

BACKGROUND AND PURPOSE: Xanthine oxidoreductase (XOR), which catalyzes purine catabolism, has two interconvertible forms, xanthine dehydrogenase and xanthine oxidase, the latter of which produces superoxide during uric acid (UA) synthesis. An association between plasma XOR activity and cardiovascular and renal outcomes has been previously suggested. We investigated the potential association between cardiac parameters and plasma XOR activity among cardiology patients. METHODS AND RESULTS: Plasma XOR activity was measured by [13C2,15N2]xanthine coupled with liquid chromatography/triplequadrupole mass spectrometry...

OBJECTIVE: Serum uric acid levels increase in postmenopausal women, but decrease when hormone therapy (HT) is administered. No study has, however, evaluated the effects of different types of HT on serum uric acid levels. We therefore examined whether estrogen therapy (ET), estrogen plus progestogen therapy (EPT), and tibolone use affected serum uric acid levels in this population. METHODS: We performed a retrospective cohort study of postmenopausal women. From 2005 to 2015, postmenopausal women who had undergone blood uric acid-level testing at least twice were enrolled...

Nilanjan Dey, Santanu Bhattacharya
A pyrene-based amphiphilic receptor has been utilized in the nanomolar detection of uric acid at physiological pH in water. The compound shows a unique concentration-dependent modulation in optical response towards uric acid. In intramolecu-lar/static excimer form (low concentration range), it displays ratiometric response, while a 'turn-off' sensing is observed specifically in the presence of intermolecular/dynamic excimer (high concentration range). The present protocol is then employed for the estimation of uric acid in blood serum samples of healthy individuals...

INTRODUCTION: One of the most important issues in patients with chronic kidney disease is fluid retention and volume overload accompanied by retention of nitrogenous waste products and some electrolytes. Bowel fluid contains high levels of urea, creatinine, uric acid, and electrolytes, which make it a potential candidate for intestinal excretion of nitrogen wastes and electrolytes. Cross-linked polyelectrolyte (CLP) is a polymer that, given orally, absorbs excess fluid, electrolyte, and nitrogenous waste products...
