Intratubular injection of electron-opaque tracers (lanthanum hydroxide, peroxidase) by micromanipulation showed that the intercellular spaces of the adluminal compartment are in continuity with the lumen of the rat seminiferous tubule at all stages of the spermatogenic cycle. This continuity involves
A polymeric microgel template/ultrasonic degradation method for the preparation of organic-inorganic nano-composites is proposed and successfully used in the preparation of poly(sodium acrylate) (PAANa) and lanthanium hydroxide nano-composites (PAANa/La(OH)(3)). The nano-composites were prepared via three steps. La(NO(3))(3) was trapped within
A new and simple method to directly synthesize stable and crystalline pure phase La(OH)(3) nanorods was developed using cationic surfactant (cetyltrimethylammonium bromide, CTAB). The advantages of the method are facile synthesis, at room temperature, and low cost. X-ray diffraction (XRD)
Paracellular pathways in the haemotrichorial placenta of the rat were studied by electron microscopy using lanthanum hydroxide as an electron dense marker. Near term placentae were dually perfused in situ, adding lanthanum to the fetal perfusate. In some placentae outflow
Colloids and surfaces. B, Biointerfaces, 100, 185-189 (2012-07-07)
A novel material, sol-gel derived La(OH)(3) nanorods (La(OH)(3)NRs) with excellent film forming ability was prepared, and it was first designed to incorporate with carbon nanotubes (CNTs) to modify glassy carbon electrode (GCE) to simultaneously voltammetric determine ascorbic acid (AA), dopamine
The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.
