Background and Aim: High chipping rates of the veneering porcelain in zirconia ce-ramic restorations have been reported in many clinical studies. However, information on the bonding behavior of veneering porcelain to zirconia and lithium disilicate frameworks is limited. The purpose of this study was to evaluate the bond-ing strength of porcelain veneering to zirconia, lithium disilicate, nicke...

Considering the physiological role of epiphysis in functional activity and defense reactions of the body, this study was carried out to evaluate changes of lithium level due to biorhythms of epiphysis. For this purpose, albino mice (6-month old) were used. The animals were kept in light (resulting in inhibition of the activity of epiphysis) and dark (which increases the activity of epiphysis) e...

introduction: recombinant human thyroid-stimulating hormone(rhtsh) increases radioactive iodine uptake(raiu) in selected populations, while lithium is used as an adjunct to radioactive iodine (rai) therapy in graves’ disease with low raiu. in this report, both drugs used in combination, overcame low iodine-131 uptake in a graves’ patient. clinical case: a 39-year old female with graves’ disease...

Lithium-brine is an important potential source of lithium. Much research and investigation has been carried out aimed at lithium recovery from brine. Although the distribution and occurrence status of lithium in brine have important implications for lithium recovery, few reports had correlated to this issue. In this article, a study was carried out to explore the lithium migration behavior duri...

The unfolding of ribonuclease A by urea, guanidine hydrochloride, lithium perchlorate, lithium chloride, and lithium bromide has been followed by circular dichroic and difference spectral measurements. All three abnormal tyrosyl residues are normalized in urea and guanidine hydrochloride (delta epsilon 287 = -2700), only two are normalized in lithium bromide and lithium perchlorate (delta epsil...

BACKGROUND Analyzing 24-h urine for lithium after consumption of lithium-tagged foods or supplements provides a validated compliance marker but is laborious. OBJECTIVE Most studies involve blood sampling; therefore, we tested whether serum lithium concentration could be used as a compliance marker. DESIGN We used serum lithium as a compliance marker in a dietary trial and an evaluation stud...

Lithium was investigated for its possible use as a marker for identifying the various sources of NaCl in the diet. Micromolar concentrations of lithium can be detected in various vegetables, tap water and also in urine specimens of adult volunteers. The lithium content of vegetables varied from 6.1 to 24.5 mumol of lithium/kg dry weight, with the exception of spinach and aubergines which had mu...
