Change of Uric Acid and its Clinical Implications
"요산은 주로 뇌-심혈관계 위험인자를 많이 가지고 있는 사람들에서 증가되어 있고, 최근 뇌-심혈관계 질환의 새로운 위험인자로 대두되고 있는 대사증후군에서도 종종 증가되어 있으며, 뇌-심혈관계의 발생이나 예후를 예측할 수 있는 인자라고 알려져 있다. 하지만 요산은 우리의 몸에서 매우 강력한 항산화제이다. 한편 우리 몸 산소를 가장 많이 소비하고 산화손상의 주요 기질인 지방산이 풍부한 뇌는 근본적으로 산화손상에 취약하다. 게다가 이러한 산화손상을 일시적으로 받을 수 밖에 없는 급성 뇌경색에서 자유유리기가 폭발적으로 나오는 급성 …

Uric acid metabolism in the Dalmatian coach hound
… exhibits three characteristic abnormalities of uric acid metabolism, namely hyperuricaemia, hyperuricosuria and increased renal uric acid clearance. These properties are associated with hypoallantoinaemia and hypoallantoinuria. A result of these abnormalities is a high incidence of urate …

Spray coated bentonite/MWCNT composite enzymatic biosensor for uric acid detection
… study presents the development of an enzymatic uric acid (UA) biosensor based on a nanocomposite of bentonite (BT) and multi-walled carbon nanotubes (MWCNTs) fabricated via spray coating. The composite utilizes the high conductivity and surface area of MWCNTs along with the ion-exchange capacity …

Potential influence of serum uric acid concentration on regulation of the human cardiovascular system
… epidemiological associations between high serum uric acid concentrations and increased cardiovascular risk. However, it is unclear if uric acid is an independent causal risk factor, serves a protective role due to its antioxidant properties, or simply acts as a passive marker of risk through …

Modeling Uric Acid Kidney Stones Disease in D. melanogaster using RNAi and Dietary Modulation
… humans, the major predictor for gout and forming uric acid kidney stones is elevated uric acid in the serum and urine respectively. It is known that uric acid is an end metabolite of purine degradation in humans, but in other species from <em>D. melanogaster </em>to lower apes,<em> </em>uric acid …

Effect of dietary protein on plasma uric acid, body weight, and oxidative stress in broilers
Uric acid is an important antioxidant due to its role as a free radical scavenger, and methods to elevate its plasma concentration may be important in animal health. In a preliminary study, the effect of dietary protein on plasma uric acid (PUA) was determined in 3-wk-old chicks. Twenty-four …

Role of Protein Phosphatase-2A in Regulating Monocyte Activation by Soluble and Crystalline Uric Acid in Gout
… signals e.g. lipopolysaccharide (LPS) or soluble uric acid (UA), crystal phagocytosis and subsequent NLRP3 inflammasome activation and conversion of pro-IL-1β to active IL-1β. Protein-phosphatase-2A (PP2A) is a serine/threonine phosphatase that plays an important role in cell growth and …

The incorporation of glycine-2-C14 into urinary uric acid and serum bilirubin in normal and porphyric subjects
The porphyrias are a group of disorders characterized by the excessive excretion of haem precursors in urine and stool. in the past two decades, isotopic studies led to impressive progress in our understanding of both normal and disordered porphyrin metabolism but despite these advanaces, many …

Effect of allopurinol and hemin on some biological markers of aging in broiler chickens
Uric acid has been hypothesized as one of the most important antioxidants in limiting the accumulation of advanced glycolated endproducts in broiler breeder hens. This study was designed to quantitatively manipulate the plasma uric acid concentrations using hemin and allopurinol and determine its …

Anthropometric status, dietary intake and uric acid levels in adults aged 40 to 60 years residing in Giyani Location of Greater Giyani Municipality in Mopani District, Limpopo Province
Background: Elevated serum uric acid levels (hyperuricemia) are influenced by several dietary and lifestyle factors, including high intake of sugar, alcohol, and purine-rich foods. Hyperuricemia is a major risk factor for gout, an inflammatory condition that has become increasingly prevalent in …

Purine Degradation and Ureide Catabolism by Soybean (Glycine Max (L.) Merrill); Cell Suspension Cultures
… of growth on the ureides allantoin and allantoic acid, and their purine precursors uric acid and inosine-5$\sp\prime$-mono- phosphate (IMP), as sole nitrogen sources. The inhibitors of purine degradation, allantoxanamide and allopurinol, caused accumulation of uric acid and hypoxanthine, …

The Effect of Allopurinol and Inosine Administration on Xanthine Oxidoreductase Gene Expression, Mitochondrial Respiration, and Inflammation in Broiler Chickens
… do not, in part due to the powerful antioxidant, uric acid. As the end-product of purine degradation, uric acid is generated in the xanthine/hypoxanthine reactions catalyzed by xanthine oxiodreductase (XOR). In the first study, inosine, a purine precursor, was fed to 3 groups of 5 birds: Group 1 …

An investigation into the physiology of urate pellet excretion by Parcoblatta fulvescens (Saussure and Zehntner) (Dictyoptera: Blattellidae)
… <i>Parcoblatta fulvescens</i> were investigated. Uric acid excretion by last instar juvenile <i>P. fulvescens</i> was studied first. Food consumption, urate and non-urate pellet excretion patterns show a skewed distribution with peak feeding occurring on day six and peak voiding of both pellet …

Effect of Procedural Pain on Purines, MDA and Allantoin in Premature Infants
… pain, ATP utilization (hypoxanthine and uric acid), and oxidative stress (MDA and allantoin) in premature infants. Through these studies we found that 1) a single heel-lance significantly increases plasma uric acid in rabbit kits, 2) tape removal increases MDA and prevents a decrease in …
