Lanthanum carbonate (LaCO(3)) is an oral phosphate binder widely used in end-stage renal disease (ESRD). Preclinical animal studies reported the highest La concentrations outside the gut to be in mesenteric lymph nodes. We observed previously unreported La deposition visible by light microscopy and confirmed by scanning electron microscopy with energy dispersive x-ray spectroscopy in a mesenter...

Lanthanum substituted Ni-Zn ferrite nanoparticles (Ni0.5Zn0.5LaxFe1-xO4; 0.00 ≤x≤ 1.00) synthesized by sol-gel method were presented. X-ray diffraction patterns reveal the typical single phase spinel cubic ferrite structure, with the traces of secondary phase for lanthanum substituted nanocrystals. In addition, the structural analysis also demonstrates that the average crystallite size varied i...

Investigations were conducted on a series of calcium and lanthanum oxides catalyst for biodiesel production. Mixed oxides catalyst showed a superior transesterification activity over pure calcium or pure lanthanum oxide catalysts. The catalyst activity was correlated with surface basicity and specific surface areas. The effects of water and free fatty acids (FFA) levels in oil feedstock, water ...

2 Abstract Apatite-type lanthanum silicates/germanates have been attracting considerable interest as a new class of oxide ion conductors, whose conductivity is mediated by oxide ion interstititials. For the germanates, it has been shown that, depending on composition, the cell can be either hexagonal or triclinic, with evidence for reduced low temperature conductivities for the latter, attribut...

A laboratory plasma experiment has been built to study the eruption of arched magnetic flux ropes (AMFRs) in the presence of a large magnetized plasma. This experiment simulates the eruption of solar AMFRs in two essential steps: i) it produces an AMFR (n= 6.0 × 1012 cm−3, Te = 14 eV, B ≈ 1 kilo-gauss, L= 0.51 m) with a persistent appearance that lasts several Alfvén transit times using a lanth...

The ultrastructure of low resistance junctions between segments of lateral giant fibers in crayfish is studied in sections from specimens fixed either by conventional methods or by glutaraldehyde-H(2)O(2) or by glutaraldehyde-lanthanum. Cross sections through junctions fixed by conventional glutaraldehyde display the usual trilaminar profile of two parallel membranes separated by a narrow gap. ...

Dear Editor, A 58-year-old Asian woman hung herself. When emergency medical service arrived, she was under cardiopulmonary arrest with asystolic rhythm. Sixty minutes later, her circulation was restored and she was then transferred from a rural hospital to our hospital. When the patient was brought to our hospital, she was unconscious, and her pupils were dilated and had no light reflex. Comput...

8 The isothermal section of the La–B–C phase diagram at 1270 K has been investigated by 9 means of X-ray, neutron powder diffraction, microstructure and EPMA analyses. Eight ternary 10 compounds were found, and for six of them the crystal structures have been established. The 11 phase with the structure type of La5B2C6 has a broad homogeneity range described by the 12 formula La5(BC)x (5.6x8....

Lanthanum carbonate (LC) is used as a phosphate binder in dialysed patients. Abdominal pain and constipation are known side effects of its use. Furthermore, in radiological studies, LC tablets are seen as intense radio-opaque deposits within the entire gastrointestinal tract-findings which can lead to diagnostic misinterpretations. An elderly patient on peritoneal dialysis and taking LC present...
