Calcium and strontium ions enhanced rishitin but not lubimin accumulation in tuber tissue of potato (Solanum tuberosum cv Kennebec) treated with arachidonic acid (AA). The same cations in the presence of poly-l-lysine (PL) enhanced the accumulation of lubimin more than rishitin. In contrast, Mg(2+) did not affect AA-elicited rishitin and lubimin accumulation and inhibited the accumulation of th...

Aluminium- or calcium-based phosphate-binding agents traditionally have been used to treat hyperphosphataemia in patients with end-stage renal disease. Although these agents effectively lower serum phosphorus levels, they are associated with serious side effects. Aluminium-based agents are associated with bone toxicity, renal osteodystrophy and encephalopathy, and calcium-based agents increase ...

The effect of extracellular lanthanum on neuromuscular transmission was studied in cockroach leg muscle and larval mealworm ventral muscle by means of microelectrodes. Miniature excitatory postsynaptic potential (MEPSP) frequency was markedly increased after lanthanum was added, in the presence and absence of calcium. The potentiation by La3+ was suppressed in a high Ca2+ saline and enhanced in...

The effect of the presence of different anions on the biosorption of La(3+) (Lanthanum) using Sargassum polycystum Ca-loaded biomass was studied in this work. Different types of metal salts were used, such as nitrate, sulphate and chloride. The presence of the anion sulphate decreased the metal uptake for tested pH values of 3--5 when compared to the nitrate and chloride systems. The presence o...

BACKGROUND Serum phosphorus control is critical for chronic kidney disease (CKD) 5D patients. Currently, clinical profile for an oral phosphorus binder in the mainland Chinese population is not available. OBJECTIVE To establish the efficacy, safety, and tolerability of lanthanum carbonate in CKD 5D patients. DESIGN Multicenter, randomized, double blind, placebo-controlled study. A central r...

The extraction-separation of lanthanum and europium ions with bis(2-ethylhexyl) phosphoric acid (DEHPA) in cyclohexane was improved by adding 12-crown-4 (12C4) to the aqueous phase as a masking agent. In the presence of this crown ether the extraction curve of lanthanum ions versus pH shifts to the higher pH region, while the curve is not influenced for the europium ions. Consequently the s...

Cardiovascular mortality is the leading cause of death in the uremic patient. Hyperphosphatemia is considered an independent risk factor associated with cardiovascular morbidity and mortality in dialysis patients. As phosphate control is not efficient with diet or dialysis, phosphate binders are commonly prescribed in patients with chronic renal failure. Aluminum salts, the first phosphate bind...

BACKGROUND Lanthanum carbonate and sevelamer carbonate are non-calcium-based phosphate binders used to manage hyperphosphataemia in patients with chronic kidney disease (CKD). Patients with CKD may require intravenous or oral active vitamin D. We investigated the effects of lanthanum carbonate and sevelamer carbonate on the bioavailability of oral calcitriol. METHODS This was a three-period, ...

background: control of the phosphorus in hemodialysis patients is very important and can be done in many ways. the purpose of the study was to compare the effects of nicotinic acid and lanthanum carbonate on hyperphosphatemia in the hemodialysis patients. materials and methods: this double-blind randomized clinical trial was done in imam hossein hospital (shahroud, iran) in 2014. the participan...
