Single-frequency operation of a diode-pumped lanthanum-neodymium-hexaaluminate laser using a twisted mode geometry is reported. Single-mode output without additional intracavity frequency-selective elements was observed. The laser was tunable from 1.054 to 1.059 microm and from 1.077 to 1.088
OBJECTIVE:The present study was to investigate the effects of combined application of lanthanum,cerium and fluoride-contained gel on root surface caries.METHODS:2000ppm lanthanum.cerium and fluoride-contained gels were used by various procedures to treat 164 teeth with root surface
In order to evaluate the anticaries effects of several trace elements by combined and respective treating procedure, studies on inhibiting demineralization and improving remineralization were carried out with lanthanum, cerium and fluoride in a pH-cycling condition. The analysis of polarized
Lesioned skin tissues from a female Caiabi indian with lobomycosis were processed for routine electron microscopy using, in the initial steps, solutions containing 2% lanthanum nitrate. The pattern of tracer distribution suggests that the tracer penetrates into the cavity containing the parasite
The present study included rinses with aqueous solutions of lanthanum prior to and after traditional chlorhexidine mouthrinses. Lanthanum has an extremely high affinity for phosphate, and the experiments were designed to examine the role of this anion as a receptor site for chlorhexidine in the oral
OBJECTIVE
To compare the effect of different does of lanthanum-contained rinse solution on carious-resistance, and to investigate the acid-resistant abilities of dental enamel and root surface that treated with lanthanum-contained rinse solution.
METHODS
Human dental root surfaces were treated in
The organization of tight junctional complexes (TJs) was studied in cultured porcine thyroid cells during the inversion of polarity induced by collagen-embedding of inside-out follicles, using freeze-fracture replicas and lanthanum penetration. During the early steps of polarity reversal,
The retinular (R) cell junction between adjacent photoreceptor cells in the house-fly ommatidium was characterized by freeze fracture, thin section and tracer (lanthanum) studies. Focal tight junctions occur between cells, and some P face ridge-E face groove correspondences are present in this
The title compound, triaquatris(glutarato)dilanthanum(III) dihydrate, [[La2(C5H6O4)3(H2O)3] x 2H2O]n, is the first reported glutarate coordination polymer of lanthanum(III) without a protonated ligand. The noteworthy features in the structure are, firstly, the unusual binuclear lanthanum cage formed
We present a novel electro-optically tuned external-cavity diode laser (ECDL) that utilizes a volume Bragg grating (VBG) as the frequency selective feedback element and a piece of high electro-optic coefficient Lead Lanthanum Zirconate Titanate (PLZT) transparent ceramic as the frequency tuning
The external surface coat on mouse epidermal cells has been studied during epidermal wound healing in suction-induced intact subepidermal blisters. By sequentially incorporating the cationic dye Alcian blue and the electron opaque tracer lanthanum nitrate into the primary and secondary fixatives for
