OBJECTIVE The aim of this study in pregnant women with hypothyroidism treated by levothyroxine is to examine the interrelations between thyroid-stimulating hormone (TSH), free thyroxine (FT(4)) and free tri-iodothyronine (FT(3)), and examine whether in such patients the treatment is adequate. METHODS This was a retrospective cross-sectional study. Maternal serum concentrations of FT(3), FT(4)...

PURPOSE To compare reduced colonic cleansing based on dietary fecal tagging (FT) with standard (non-FT) colonic cleansing with regard to patient acceptance, sensitivity, and specificity. MATERIALS AND METHODS In 50 patients (FT group), FT was performed by means of diet, magnesium citrate, and a barium suspension. In another 50 patients (non-FT group), preparation was based on polyethylene gly...

BACKGROUND The growing interest in measuring blood free testosterone (FT) is constrained by the unsuitability of the laborious reference methods for wider adoption in routine diagnostic laboratories. Various alternative derived testosterone measures have been proposed to estimate FT from either additional assay steps or calculations using total testosterone (TT) and sex hormone-binding globulin...

In this note we prove the backwards uniqueness of the mean curvature flow in codimension one case. More precisely,let Ft, e Ft : M → M n+1 be two complete solutions of the mean curvature flow on M×[0, T ] with bounded second fundamental form in a complete ambient manifold with bounded geometry. Suppose FT = e FT , then Ft = e Ft on M n × [0, T ]. This is an analog of a recent result of Kotschwa...

The Drosophila protocadherin Fat (Ft) regulates growth, planar cell polarity (PCP) and proximodistal patterning. A key downstream component of Ft signaling is the atypical myosin Dachs (D). Multiple regions of the intracellular domain of Ft have been implicated in regulating growth and PCP but how Ft regulates D is not known. Mutations in Fbxl7, which encodes an F-box protein, result in tissue ...

FLOWERING LOCUS T (FT) encodes a systemic signal communicating the perception of long day photoperiod from leaves to the shoot apex to induce the floral transition. Transient expression of FT in the phloem companion cells of rosette leaves for one to several days was previously shown to be sufficient to commit plants to flowering. Here we show that partial commitment results in pleiotropic infl...
