The epsilon domain of Hepatitis B virus plays a crucial role in encapsidation of viral pregenomic RNA and its partial NMR structure has been determined. However, we recently described a potassium-dependent ribonucleolytic activity associated with this region, so that a 53 nt long RNA containing the epsilon domain could release itself and cleaved ot...

Potassium is an inorganic mineral element in biomass and has a significant catalytic effect on biomass pyrolysis. In this work, the effect of potassium on the pyrolysis of biomass components (cellulose, xylan and lignin) was investigated with the help of thermogravimetric analyzer coupled to fourier transform infrared spectrometer (TG-FTIR) and pyr...
The aim of this study was to evaluate the nutrient fluxes for lactating cows in a pasture-based dairy system and the impact of a nutritional management strategy on the environmental performance indicators. Fourteen lactating cows were divided into two experimental groups with seven animals each. The nutritional managements were a diet containing 20...

Plant physiology and development essentially depend on sufficient uptake of various essential nutritive ions via their roots and their appropriate transport and distribution within the organism. Many of these essential nutrients are heterogeneously distributed in the soil or are available in fluctuating concentrations. This natural situation requir...

The macronutrient potassium (K) has vital physiological functions in plants and its availability can strongly impact quality of crops like tomato. The impact of K nutrition on conventional tomato fruit quality parameters has been described several times, but detailed investigations on the effect of K supply on the fruit metabolite profile are still...
The objective of this work was to evaluate the influence of irrigation and fertilization with nitrogen and potassium on the sterol and triterpene dialcohol contents in two trials of cv. Arbequina in super-intensive orchards in Madrid and Lleida (Spain), using a completely randomized block design. No significant differences in total sterols between ...

High potassium intake has been suggested to lower the risk for renal and cardiovascular outcome, but data are conflicting. This may be explained by the use of different methods for potassium intake assessment across studies. Also, most data are limited to the general population. We investigated the optimal potassium intake, as measured with multipl...

BackgroundEstimates of daily sodium (Na) and potassium (K) excretion were explicitly biased when using equations for adults. We aimed to develop equations to estimate them using overnight urine from Japanese children and adolescents.MethodsThe subjects comprised 70 students aged 10.49–15.76 years: validation group, n = 34; and verification group, n...

BackgroundFinger millet, a subsistence food crop, is a unique cereal with high nutritional quality particularly in hilly regions in Nepal. Hence, grain nutrients (protein, calcium, and iron percent) of ten different landraces of finger millet and soil quality (SOC, N, P and K) at different altitudes in central Nepal were analyzed.MethodsTriplicate ...

Although low sodium intake (3·5g/day) are proposed as public health interventions to reduce stroke risk, there is uncertainty about the benefit and feasibility of this combined recommendation on prevention of stroke and its subtypes. We obtained random urine samples from 9,275 cases of acute first stroke and 9,726 matched controls (8,761 matched pa...
