Shear bond strength of resin cement on moist dentin and its relation to the flexural strength of resin cement.

We sought to compare the bond strength of resin cement on moist dentin to that on dry dentin, and determine the relationship between the bond strength and flexural strength of resin cement. The water content of the moist and dry dentins was estimated using infrared spectroscopy. Four adhesive and three self-adhesive resin cements were used.

Use of an intraoperative navigation system and piezoelectric surgery for styloidectomy in a patient with Eagle's syndrome: a case report.

Background: Elongated styloid process syndrome (Eagle's syndrome) is the term given to the symptomatic elongation of the styloid process or the mineralization of the stylohyoid or stylomandibular ligament. The two commonly used approaches for the surgical treatment of this syndrome are the transcervical and transoral approaches. Both have their limitations and specific intraoperative risks.

Single-shot magnetic resonance spectroscopic imaging with partial parallel imaging.

A magnetic resonance spectroscopic imaging (MRSI) pulse sequence based on proton-echo-planar-spectroscopic-imaging (PEPSI) is introduced that measures two-dimensional metabolite maps in a single excitation. Echo-planar spatial-spectral encoding was combined with interleaved phase encoding and parallel imaging using SENSE to reconstruct absorption mode spectra. The symmetrical k-space trajectory compensates phase errors due to convolution of spatial and spectral encoding.

Zinc is involved in the expression of a nuclear-encoded alternative oxidase gene in the yeast Hansenula anomala.

When Hansenula anomala cells were treated by the combined addition of pyrithione, a zinc ionophore, and metal chelating agents such as EDTA and N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine, the antimycin A3-dependent induction of cyanide-resistant respiratory activity was suppressed. Among the chelators we tested, Zn-saturated EDTA failed to sustain the inhibitory effect, and added zinc ions restored the induction in the treated cells. Further, the antimycin A3-inducible mRNA level of the nuclear-encoded alternative oxidase gene detected by reverse transcriptase-PCR was significantly decreased by the treatment, and recovered to the level of untreated cells upon the addition of zinc ions.
