Objective(s) It is believed that the mesenchymal stem cell (MSC) differentiation and proliferation are the results of activation of wnt signaling pathway. On the other hand, lithium chloride is reported to be able to activate this pathway. The objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived MSC. Materials and ...

Experiment 1 sought to determine whether schedule-induced drinking could be abolished by means of a taste aversion. Polydipsic rats were given access to a .4% saccharin solution while they were exposed to an intermittent food schedule. Immediately after the session, they received an intraperitoneal injection of either lithium chloride or sodium chloride. Following a recovery day with water in t...

Electron probe x-ray microanalysis of the composition of rabbit portal anterior mesenteric vein smooth muscle was performed following sodium loading and washout into sodium-free lithium solutions. Sodium and lithium were also measured with atomic absorption spectrophotometry. Cellular uptake of sodium and loss of potassium during sodium loading were much faster at high (37 degrees C) than at lo...

background:   objective: this study was designed to evaluate effects of lithium chloride on the release of steroid hormones and steroidogenic enzymes in gonadotropin-stimulated rats.   materials and methods: immature 23 days old wistar rats were divided into 10 groups; each group comprised of 8 rats, and induced with single injection of pregnant mare’s serum gonadotrophin (pmsg) and followed by...

objective: the influence of cholinergic drugs on lithium-induced statedependent learning has been investigated in adult male mice. method: a single-trial step-down inhibitory avoidance task was selected. the drugs used in the study were lithium chloride physostigmine , nicotine hydrogen tartrate and scopolamine hydrobromide, atropine sulphate. the drugs were administrated through the peritoneal...

The physics of the dew cell sensor are investigated and the resulting limitations upon application and errors in use are discussed. Specific consideration is given to the measurable range of dew point temperatures and relative humidities, response at different temperatures and under different aspiration conditions, and to errors arising from change in the water of hydration of lithium chloride ...

There are two errors in Scheme 32 on page 6987. The first is that the substituted phenylmagnesium bromide-lithium chloride complex reagent (left) should be substituted pyridylmagenesium bromide-lithium chloride in the synthesis of GSK 269984B in the middle of Scheme 32. The structure should appear as follows: The second error, in the last row of Scheme 32 is that the structures of the fluoroqui...

The main goal was to standardize the FETAX (Frog Embryos Teratogenesis Assay: Xenopus) test. Since lithium ions are known to be teratogenic for embryos of many organisms, they were prefferred for our first standardization assay. Xenopus laevis embryos were exposed to lithium chloride (from 2x10–4 to 6 x 10–3 M concentrations) for 96 hours at 2–4 cell stages of development. Exposure to lower LiC...

Experiments are described, showing that DNA solutions with lithium chloride present a hypochromicity, which increases with the molarity of the salt. Different absorbancy versus temperature curves are obtained for different solutions, and it is found that the melting point (Tm) increases with the lithium chloride concentration. When cooling the samples, the absorbancy decreases in a symmetric wa...
