Hemoglobin glycation index (HGI), defined as the difference between the observed HbA1c value and the value of HbA1c predicted from plasma glucose levels, represents a measure of the degree of non-enzymatic glycation of hemoglobin and it has been found to be positively associated with micro- and macro-vascular complications in subjects with type 2 diabetes. To investigate the pathophysiological abnormalities responsible for the increased cardiovascular risk of patients with higher HGI, we evaluated the association of HGI with cardio-metabolic characteristics in nondiabetic offspring of type 2 diabetic individuals...

BACKGROUND/AIM: Psoriasis has been accepted as a systemic disease and it is known to be associated with various disorders including metabolic syndrome. High serum uric acid levels are also associated with the components of metabolic syndrome. In this study, we aimed to determine serum uric acid levels in patients with psoriasis and the association of uric acid levels with disease activity by taking the presence of metabolic syndrome criteria into account, since it is one of the most important factors that affect serum uric acid levels...

Emma D Deeks
Lesinurad (Zurampic(®)) is an oral selective inhibitor of the URAT1 and OAT4 uric acid (UA) transporters of the kidney, via which it inhibits UA reabsorption and thus increases renal UA excretion and lowers serum UA (sUA) levels. Lesinurad 200 mg once daily is indicated for use in combination with a xanthine oxidase inhibitor (XOI) to treat hyperuricaemia in adults with gout who have not achieved target sUA levels with an XOI alone. Approval was based on three 12-month phase 3 trials that evaluated lesinurad in combination with allopurinol in adults with gout inadequately responsive to allopurinol (CLEAR 1 and 2) and in combination with febuxostat in adults with tophaceous gout (CRYSTAL)...

BACKGROUND AND AIMS: Metabolic Syndrome (Mets) and increased serum uric acid (SUA), are well known renal risk predictors and often coexist in patients with type 2 diabetes (T2D). Whether they independently contribute to the onset of CKD is at present unclear. METHODS AND RESULTS: Within the AMD Annals database we identified patients with T2D and normal renal function and urine albumin excretion at baseline and regular follow-up visits during a 4-year period. Blood pressure, BMI, HDL, triglycerides, and SUA were available in 14,267 patients...

There is a direct relationship between fructose intake and serum levels of uric acid (UA), which is the final product of purine metabolism. Recent preclinical and clinical evidence suggests that chronic hyperuricemia is an independent risk factor for hypertension, metabolic syndrome, and cardiovascular disease. It is probably also an independent risk factor for chronic kidney disease, Type 2 diabetes, and cognitive decline. These relationships have been observed for high serum UA levels (>5.5 mg/dL in women and >6 mg/dL in men), but also for normal to high serum UA levels (5-6 mg/dL)...

The demands for electrochemical sensor materials with high strength and durability in physiological conditions continue to grow and novel approaches are being enabled by the advent of new electromaterials and novel fabrication technologies. Herein, we demonstrate a probe-style electrochemical sensor using highly flexible and conductive multi-walled carbon nanotubes (MWNT) yarns. The MWNT yarn-based sensors can be fabricated onto micro Pt-wire with a controlled diameter varying from 100 to 300 µm, and then further modified with Nafion via a dip-coating approach...

Surfactant exfoliated 2D hexagonal Boron Nitride (2D-hBN) nanosheets are explored as a potential electrochemical sensing platform and evaluated towards the electroanalytical sensing of dopamine (DA) in the presence of the common interferents, ascorbic acid (AA) and uric acid (UA). Surfactant exfoliated 2D-hBN nanosheets (2-4 layers) fabricated using sodium cholate in aqueous media are electrically wired via a drop-casting modification process onto disposable screen-printed graphite electrodes (SPEs). We critically evaluate the performance of these 2D-hBN modified SPEs and demonstrate the effect of 'mass coverage' towards the detection of DA, AA and UA...

Uric acid (UA) and folic acid (FA) are compounds of biomedical interest. In humans, about 70% of daily uric acid disposal occurs via the kidneys, and in 5-25% of humans, impaired renal (kidney) excretion leads to hyperuricemia. Folate is another form folic acid of which is known as, is one of the B vitamins. It is used as a supplement by women to prevent neural tube defects developing during pregnancy. Polyortho-methoxyaniline nanostructures (POMANS) was synthesized with a new two phase (organic-water) synthesis method...

BACKGROUND: Formerly, hyperuricemia was mainly restricted to the rich population, but now-a-days it is a condition affecting wide parts of western civilization. Although only a minority of our population develops clinically relevant symptomatic hyperuricemia, there is growing evidence that elevated serum uric acid levels might be associated with elevated cardiovascular risk and cardiovascular disease progression. But it is not clear whether uric acid is just a biomarker or exerts detrimental effects itself...

Clozapine is one of the most promising medications for managing schizophrenia but it is under-utilized because of the challenges of maintaining serum levels in a safe therapeutic range (1-3μM). Timely measurement of serum clozapine levels has been identified as a barrier to the broader use of clozapine, which is however challenging due to the complexity of serum samples. We demonstrate a robust and reusable electrochemical sensor with graphene-chitosan composite for rapidly measuring serum levels of clozapine...

Biological drugs are exquisitely tailored components offering the advantages of high specificity and efficacy that are considered safe for treating diseases. Nevertheless, the effectiveness of biological drugs is limited by their inherent short biological half-life and poor stability in vivo. Herein, we engineered a novel delivery platform based on hybrid injectable hydrogels, in which pH- and temperature-responsive biodegradable copolymers were site-specifically coupled to the sulfhydryl group of human serum albumin, which effectively enhances the stability and circulation half-life of the biological drug, recombinant uricase enzyme (Uox)...

As a proof of concept, here it is established that curcumin integrated chitosan oligosaccharide lactate (COL) self-assembles on silica nanoparticle surface to form nano hybrid particles (NHPs). These NHPs have size in the ranges of 25-35nm with silica nanoparticle as its core and curcumin-COL as outer layer having thickness of 4-8nm. The fluorescence intensity of these NHPs are found to be quenched and emission maximum is ~50nm red shifted compared to free curcumin implying inner filter effect and/or homo-FRET between curcumin molecules present on the surface of individual nano hybrid particle...
