we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-...

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...

conclusions our study demonstrated that the b1 gene, more so than the re gene, showed positive samples and can be used to detect toxoplasmosis, although the b1 gene, in comparison to the re gene, did not show any superiority of molecular diagnosing capability. results also showed that toxoplasma molecular detection methods can be used instead of routine serological detection methods in a clinic...

thinking simultaneously of humor and battlefield is hardly expectable; however, the most genuine jokes can be seen in this very battlefield verbal culture in a simple and sensitive form which has rarely been paid attention to. this witticism can be categorized into four classes; namely, devotional, fight and martyrdom, drinking and eating, and social interactions which have the most similitude ...

Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...

Economists know how to calculate optimal prices for electricity transmission. These are rarely applied in practice. This paper develops a thirteen node model, based on the transmission system in England and Wales, incorporating losses and transmission constraints. It is solved with optimal prices, and with uniform prices for demand and for generation, but re-dispatching to take account of trans...

A number of attitudinal expressions are identified and analyzed using dependency based syntactic analysis. A claim is made that attitudinal loading of lexical items is dynamic rather than lexical and that attitudinal loading of individual lexical items is acquired through their use in attitudinally loaded structures.
