Deprotonation of 8bH-tetrabenzo[a,c,g,i]fluorene (8bH-Tbf), an extremely large benzannulated cyclopentadienyl derivative, by [NR3R'][OH] (R = (n)Bu, Et; R' = (n)Bu, Et, Bn) leads to a series of Tbf ammonium salts of the type [NR3R'][Tbf]. These cyclopentadienide analogs were smoothly isolated from a hydrous medium and structurally characterized by single X-ray diffraction. Subsequent reactions ...

We have studied the in vitro interactions of amphotericin B (AMB) with terbinafine (TBF), itraconazole, voriconazole (VCZ), albaconazole, and ravuconazole (RVZ), as well as TBF combined with the same azoles, against 11 isolates of Fusarium spp. using the fractional inhibitory concentration index. The highest percentage of synergistic interactions was observed for the combinations AMB-RVZ, TBF-V...

Background: The nucleus raphe magnus (NRM) is involved in thermoregulatory processing. There is a correlation between changes in the firing rates of the cells in the NRM and the application of the peripheral thermal stimulus. Introduction: we examined the effect of reversible inactivation and excitation of NRM on mechanisms involved in tail blood flow (TBF) regulation in hypothermia. Methods: H...

Tail blood flow (TBF) in the rat markedly increases during sympathetic withdrawal such as hyperthermia or lumbar sympathetic blockade. However, a long-term alteration of TBF after chronic sympathetic denervation is not well understood. In the present study, TBF following lumbar sympathectomy (LSX) was observed to ascertain whether subsequent changes in TBF occur in the absence of the sympatheti...

In this paper, we introduce an efficient real-time decision diagram, TBF BDD, characterizing both logical functionality and timing information of circuits. In contrast to the conventional timing methods that discretize time, this decision diagram permits real and continuous time and is applicable to both combinational and synchronous sequential circuits. First, we demonstrate how circuits can b...

UNLABELLED Noninvasive methods for quantifying tumor blood flow (TBF) have a potentially important role in the field of drug development. (15)O-water PET has been used in several studies aimed at monitoring response to novel treatments. Assessing the significance of changes in TBF requires knowledge of the reproducibility of the technique. This article quantifies the reproducibility of the (15)...

The components of body composition were studied in 56 second class rugby union football players: 28 forwards and 28 backs. Fowards were found to have 19.5% TBF (TOTAL BODY FAT) and 80.5% LBM (LEAN BODY MASS); backs 12.2% TBF and 87.8% LBM. It was felt that greater attention should be given to the ratio of TBF to LBM in determining body weight and that there should be an increased emphasis of th...
