The existence of the cyclotron & PET centre of UJV Rez, a.s., at Masaryk Memorial Cancer Institute allows the Masaryk Memorial Cancer Institute and RECAMO researchers to engage in the research, development and application of new radiopharmaceuticals including compounds labelled by short-living positron emitters (especially [11C]). Currently, a [11C]-labelled tracer, L-[methyl-11C]methionine, is...

In the survey paper, along one of several main lines of bounding the ratio of two gamma functions, the authors retrospect and analyse Wendel’s double inequality, Kazarinoff’s refinement of Wallis’ formula, Watson’s monotonicity, Gautschi’s double inequality, Kershaw’s first double inequality, and the (logarithmically) complete monotonicity results of functions involving ratios of two gamma or q...

Background Trigeminal Neuralgia is characterized by episodic severe facial pain possibly the result of “pulsatile” compression of the nerve Root Entry Zone (REZ) of the Trigeminal Nerve (TN) by the adjacent superior cerebellar artery (SCA). The exact role of pulsatility of SCA remains unknown and currently no methods are available to measure the pulsatility of the SCA. Herein we investigate the...

This paper establishes in two completely different ways that the abstract degenerate initial value problem —(Mu(t)) + Lu{t) = f(t),Q < t < r ,Mu(0) = Uh Muo, has always an integrated solution, provided that for ali complex numbers z in the half-plane Rez > a > 0 the operator pencil P(z) = zM + L has a bounded inverse from the Banach space X to T>(L), endowed with the graph-norm, and its norm ha...

Until now only six out of the 51 species which constitute the genus Packera (Weber and LoK ve, 1981) had been studied chemically (Pettit et al., 1980; Bohlmann et al., 1981; McCoy et al., 1983; Zalkow et al., 1988; PeH rez et al., 1991; Bah et al., 1994). In order to contribute to the chemistry of the genus, we decided to study Packera coahuilensis (Grenm.) C. Je!rey (MEXU 781268) and Packera b...
