Natamycin has been widely applied in medical treatments and food protection widely due to its effective inhibition to the growth of yeast and mold. As polyene macrolide antibiotic, the biosynthesis pathway of natamycin is relatively clear. To regulate the biosynthesis of natamycin, additions of precursors affecting cell growth and natamycin production were investigated. The results showed that 0.003% (w/v) potassium ferrocyanide and sodium propionate: n-butanol at a ratio of 4:1 was added into the broth at 0 h and 24 h respectively and they contributed to yield natamycin, reaching 1...

BACKGROUND & AIMS: In June 2016, South Africa implemented legislation mandating maximum sodium levels in a range of processed foods with a goal of reducing population salt intake and disease burden from hypertension. Our aim was to explore the relationship between salt and blood pressure (BP) in a subsample of the World Health Organization Study on global AGEing and adult health (SAGE) Wave 2 before implementation of legislation in South Africa. METHODS & RESULTS: Blood pressure (BP) was measured in triplicate (n = 2722; median age 56 years; 33% male) and 24-h urine collected in a nested subsample (n = 526) for sodium, potassium and creatinine analysis...

The effect of potassium iodide (KI) and sodium nitrite (NaNO₂ inhibitor on the corrosion inhibition of mild steel in chloride bicarbonate solution has been studied using electrochemical techniques. Potentiodynamic polarisation data suggest that, when used in combination, KI and NaNO₂ function together to inhibit reactions at both the anode and the cathode, but predominantly anodic. KI/NO₂(-) concentration ratios varied from 2:1 to 2:5; inhibition efficiency was optimized for a ratio of 1:1. The surface morphology and corrosion products were analysed using scanning electron microscopy (SEM) and X-ray diffractometry (XRD)...

This study aimed to evaluate the urinary excretion of sodium and potassium, and to estimate the main food sources of sodium in Maputo dwellers. A cross-sectional evaluation of a sample of 100 hospital workers was conducted between October 2012 and May 2013. Sodium and potassium urinary excretion was assessed in a 24-h urine sample; creatinine excretion was used to exclude unlikely urine values. Food intake in the same period of urine collection was assessed using a 24-h dietary recall. The Food Processor Plus(®) was used to estimate sodium intake corresponding to naturally occurring sodium and sodium added to processed foods (non-discretionary sodium)...

Dietary intake is pointed as one of the major determinants in hypertension development. Data in the area are mostly obtained from cross-sectional studies. We aimed to investigate the prospective association between (1) individual nutritional factors and (2) adherence to the Dietary Approach to Stop Hypertension and the risk of incident hypertension in a large cohort study. We prospectively examined the incidence of hypertension among 80 426 French adults participating in the NutriNet-Santé cohort study. Self-reported sociodemographic, lifestyle health questionnaires and dietary consumption assessed by three 24-hour records were completed at baseline and yearly thereafter...

In 2011, the accident at the Fukushima-Daiichi nuclear power plant dispersed radioactive cesium throughout the environment, contaminating the land, rivers, and sea. Suspended particles containing clay minerals are the transportation medium for radioactive cesium from rivers to the ocean because cesium is strongly adsorbed between the layers of clay minerals, forming inner sphere complexes. In this study, the adsorption and desorption behaviors of radioactive cesium from suspended clay particles in river water have been investigated...

Primary aldosteronism (PA) is the most common form of secondary hypertension (HTN), with an estimated prevalence of 4% of hypertensive patients in primary care and around 10% of referred patients. Patients with PA have higher cardiovascular morbidity and mortality than age- and sex-matched patients with essential HTN and the same degree of blood pressure elevation. PA is characterized by an autonomous aldosterone production causing sodium retention, plasma renin supression, HTN, cardiovascular damage, and increased potassium excretion, leading to variable degrees of hypokalemia...

Cardiovascular risk management is an integral part of treatment in Type 2 Diabetes Mellitus (T2DM), and requires pharmacological as well as nutritional management. We hypothesize that a systematic assessment of both pharmacological and nutritional management can identify targets for the improvement of treatment quality. Therefore, we analysed blood pressure (BP) management in the DIAbetes and LifEstyle Cohort Twente (DIALECT). DIALECT is an observational cohort from routine diabetes care, performed at the ZGT Hospital (Almelo and Hengelo, The Netherlands)...

REVIEW
Toshiyuki Iwahori, Katsuyuki Miura, Hirotsugu Ueshima
Pathogenetic studies have demonstrated that the interdependency of sodium and potassium affects blood pressure. Emerging evidences on the sodium-to-potassium ratio show benefits for a reduction in sodium and an increase in potassium compared to sodium and potassium separately. As presently there is no known review, this article examined the practical use of the sodium-to-potassium ratio in daily practice. Epidemiological studies suggest that the urinary sodium-to-potassium ratio may be a superior metric as compared to separate sodium and potassium values for determining the relation to blood pressure and cardiovascular disease risks...

Food in industrialized countries is rich in processed products with a high sodium and low potassium content. There is abundant evidence in the literature depicting the relationship between a high daily sodium/potassium intake ratio and the high prevalence of arterial hypertension in modern societies. There is also increasing evidence suggesting a blood pressure lowering effect of potassium, especially in cases of high sodium intake or in patients with increased salt sensibility. Our dietary advice for the prevention and treatment of hypertension should follow a thorough evaluation of our patients' daily nutritional habits and should not only focus on sodium intake but also aim for a balanced sodium/potassium uptake...

The substitution of potassium ions (K(+)) by sodium ions (Na(+)) in the nutrition of plants is restricted. It was shown earlier that net protein synthesis is the process which is most sensitive to the substitution of K(+) by Na(+) in young sugar beet. We hypothesized that the activity of ribosomes is inhibited by the substitution. This hypothesis was tested in an in vitro approach. Cytosolic polysomes were isolated from growing leaves of sugar beet and maize by means of differential centrifugation. In vitro systems of both plant species were tested for functionality and comparability...
