The purpose of this study was to assess tracer uptake (%ID/g) in tumor-bearing mice and the relationship between uptake values and Ki-67 expression. In our model experiment, accumulation of the tracer in the tumor samples correlates with its malignancy which indicates that 18F-FLT could be a feasible PET tracer.

Begonias hold significant importance due to their use as culinary plants, medicinal remedies, decorative elements, and high-value crops. This research aims to find new explant materials for regeneration shoots and direct flowering with high frequency. In this study, high frequency shoot regeneration and in vitro flowering from petal explants of Begonia x hiemalis Fotsch were achieved. Whole petal explants disinfected with an AgNPs solution at 0.5 g/L for 15 min achieved the highest survival rate.

In this study, the antidengue virus activity of the ethanol extract from the leaves and twigs of E. cyathophora on four virus serotypes DENV1-DENV4 was examined. The result showed that the ethanol extract displayed antidengue activity on DENV1-4 with PRNT50 values of 15.625-62.5 µg/mL. This extract was fractionated to the n-hexane and ethyl acetate fractions.

In parallel with these results, the diagrams of Gibbs et al. supported the same seawater intrusion phenomena. Brackish karst springs first roseand then fell below sea level with epirogenic movements during the geological period, and therefore, karstification progressed. The samples were oversaturated with calcite, dolomite, and quartz, whereas they were undersaturated with gypsum and halite. The Al, Cu, and Zn values of some of the water samples exceeded the tolerance limit of aquatic life standards.

Wet periods are evidenced by dark olive green mixed lithology (sandy, clay, and silts) and high values in MS and log(Sr/Ca). On the other hand, dry periods are associated with light olive green clayey mud lithology and high values in log(Ca/K). We relate the wet periods to negative North Atlantic Oscillation (NAO–) and the dry periods to NAO+. Additionally, all wet periods are related with time of low solar activity and dry periods, except Dalton Minimum, are related with periods of high solar activity.

In recent years, seismicity has increased considerably in the Aegean Sea region and there have been earthquakes in which people lost their lives. The major earthquakes, Kos Island-Gökova Bay (Mw = 6.6), Lesvos Island-Karaburun (İzmir) (Mw = 6.2) and Samos Island-Aegean Sea (Mw = 6.9) occurred in the Aegean Sea and affected Aegean region strongly. Within the scope of this study, the seismic b-value of these major earthquakes was calculated in order to perform earthquake statistical analysis.

The antimitotic depsipeptide dolastatin 15 was radiolabeled with tritium in its amino-terminal dolavaline residue. Dolastatin 15, although potently cytotoxic, is a relatively weak inhibitor oftubulin assembly and does not inhibit the binding ofany other ligand to tubulin. The only methodo-logy found to demonstrate an interaction between the dep-sipeptide and tubulin was Hummel–Dreyer equilibrium chromatography on Sephadex G-50 superfine. The average apparent Kd value obtained in these studies was about 30lM, with no difference observed when column size or tubulin concentration was varied....

The order of subject and object is an adequate criterion for distinguishing between them when other grammatical properties are ambiguous.HARPERl AND LEHISTE2 have discussed the order of subjects and predicates in Russian scientific text. Lehiste concludes that "form and function" should be used to distinguish the subject from the predicate of a Russian sentence; although her conclusion may be accepted (subject to assumptions about the value of maintaining customary English order in the output), her dictum must be converted into programmable instructions....

We have investigated the existence of a precoupled form of the distal C-ter-minal truncated cannabinoid receptor 1 (CB1-417) and heterotrimeric G proteins in a heterologous insect cell expression system. CB1-417 showed higher production levels than the full-length receptor. The production lev-els obtained in our expression system were double the values reported in the literature.

Suppose that G is a locally compact abelian group, and write M(G) for the algebra of bounded, regular, complex-valued measures under convolution. A measure µ ∈ M(G) is said to be idempotent if µ ∗ µ = µ, or alternatively if µ takes only the values 0 and 1. The Cohen-Helson-Rudin idempotent theorem states that a measure µ is idempotent if and only if the set {γ ∈ G : µ(γ) = 1} belongs to the coset ring of G, 1. Introduction Let

We prove that in every finitely generated profinite group, every subgroup of finite index is open; this implies that the topology on such groups is determined by the algebraic structure. This is deduced from the main result about finite groups: let w be a ‘locally finite’ group word and d ∈ N. Then there exists f = f (w, d) such that in every d-generator finite group G, every element of the verbal subgroup w(G) is equal to a product of f w-values.

Let E be an elliptic curve over Q, let p be an ordinary prime for E, and let K be an imaginary quadratic field. Write K∞/K for the anticyclotomic Zp-extension of K and set G∞ = Gal(K∞/K). Following a construction of Section 2 of [BD1] which is recalled in Section 1, one attaches to the data (E,K, p) an anticyclotomic p-adic L-function Lp(E,K) which belongs to the Iwasawa algebra Λ := Zp[[G∞]]. This element, whose construction was inspired by a formula proved in [Gr1], is known, thanks to work of Zhang ([Zh, §1.

MULTIPLE SOLUTIONS FOR QUASILINEAR ELLIPTIC NEUMANN PROBLEMS IN ORLICZ-SOBOLEV SPACES NIKOLAOS HALIDIAS AND VY K. LE Received 15 October 2004 and in revised form 21 January 2005 We investigate the existence of multiple solutions to quasilinear elliptic problems containing Laplace like operators (φ-Laplacians).

SAMKO Received 9 July 2004 We study the Riemann boundary value problem Φ+ (t) = G(t)Φ− (t) + g(t), for analytic functions in the class of analytic functions represented by the Cauchy-type integrals with density in the spaces L p(·) (Γ) with variable exponent. We consider both the case when the coefficient G is piecewise continuous and the case when it may be of a more general nature, admitting its oscillation.

Let G be a graph with vertex set V (G) = {1, . . . , n} and edge set E(G). We are interested in studying the functions of the graph G whose values belong to the interval [(G), (G)]. Here (G) is the size of the largest stable set in G and (G) is the smallest number of cliques that cover the vertices of G. It is well known (see, for example, [1]) that for some  0 it is impossible to approximate in polynomial time (G) and (G) within a factor of n, assuming P 6= NP. We suppose that better approximation could...
