was added to the well, and the lumi-nescence was measured (ALOKA lu-minometer). The IgG fraction of serum samples from the patient and from five control individuals was purified with a MAbTrap TM Kit (Amer-sham Biosciences), and the IgG concentration was adjusted to 4.0 g/L. The purified IgG (0.08 mL) was incu-bated at 4 °C for 24 h with 0.08 mL of PBS alone or with T 2 , T 3 , or T 4 (Sig-ma; ...

Signals produced in leaves are transported to the shoot apex where they cause flowering. Protein of the gene FLOWERING LOCUS T (FT) is probably a long day (LD) signal in Arabidopsis. In the companion paper, rapid LD increases in FT expression associated with flowering driven photosynthetically in red light were documented. In a far red (FR)-rich LD, along with FT there was a potential role for ...

Let t=t1t2⋯ be an element of the full shift with map τ on a finite alphabet symbols A and let Σ=closure{τi(t):i∈N∪{0}}. ft=ft1,∞=⋯∘ft2∘ft1 non-autonomous system over compact metric space X where ti∈A. The set Ft+={fτi(t):i∈N} is called shifted family ft. If t transitive in AN, then Ft+‾ classical IFS; otherwise, Σ subshift Ft+‾={fσ=fσ1,∞:σ∈Σ} “generalized” IFS. We show that if ft has some shado...

The production of erythrocytes bearing an "immature" antigen (Im+ cells) and a "fetal" antigen (Ft+ cells) has been studied in irradiated adult mice grafted either with fetal liver or adult bone marrow cells. The Im+ cells reach a peak 8-11 days after grafting. Ft+ cells are detected only after graft of fetal liver cells; the younger the liver, the greater the number. Since Ft+ cells are rapidl...

BACKGROUND The clinical value of free thyroxine (FT(4)) and free triiodothyronine (FT(3)) analysis depends on the reference intervals with which they are compared. We determined age- and sex-specific reference intervals for neonates, infants, and children 0-18 years of age for FT(4) and FT(3) using tandem mass spectrometry. METHODS Reference intervals were calculated for serum FT(4) (n = 1426...
