Colorectal cancer has emerged as a major cause of death in Western countries. Down-regulation of β-catenin expression has been considered a promising approach for cytotoxic drug formulation. Eight 4,9-friedodrimane-type sesquiterpenoids (1-8) were acquired using the oxidative potential of Verongula rigida on bioactive metabolites from two Smenospongia sponges. Compounds 3 and 4 contain a 2,2-di...

Fifteen strains of chlamydial agents, 2 Chlamydia trachomatis and 13 Chlamydia psittaci, were tested for plaque formation on chick embryo fibroblast cells. C. trachomatis strains did not form plaques; 12 strains of C. psittaci did form plaques and 1 strain did not. The distribution of plaque sizes with C. psittaci strains was studied and it was found that the 12 strains could be tentatively gro...

We give holomorphic Chern-Simons-like action functionals on supertwistor space for self-dual supergravity theories in four dimensions, dealing with N = 0, . . . , 8 supersymmetries, the cases where different parts of the Rsymmetry are gauged, and with or without a cosmological constant. The gauge group is formally the group of holomorphic Poisson transformations of supertwistor space where the ...

In order to assess possible observable effects of noncommutativity in deformations of quantum mechanics, all irreducible representations of the noncommutative Heisenberg algebra and WeylHeisenberg group on the two-torus are constructed. This analysis extends the well known situation for the noncommutative torus based on the algebra of the noncommuting position operators only. When considering t...

In commercially raised poultry, chlamydiosis mostly seems to occur on turkey or duck farms, sometimes associated with zoonotic transmission and disease (psittacosis) in humans. However, Chlamydia infections are apparently emerging in chickens, and information on the virulence of Chlamydia in chickens is limited. Up-to-date Chlamydia psittaci genotypes B and D are most frequently found in broile...

The C( He,d) N proton transfer reaction has been measured at an incident energy of 26.3 MeV. Angular distributions for proton transfer to the ground state and excited states at 2.313 and 3.948 MeV in N are analyzed within the framework of the modified DWBA. Asymptotic normalization coefficients ~ANC’s! defining the amplitude of the tails of the N bound-state wave functions in the C1p channel ar...

Storage proteins in cotyledons of legume plants are degraded by proteinases after germination. We examined whether abscisic acid (ABA), gibberellin (GA) and brassinosteroid (BR) are involved in the expression of cysteine proteinases in cotyledons of common bean seeds with RNA blotting using cDNAs for five papain-like proteinases, EP-C1, CP1, CP2, CP3, CP4 and two legumain-like proteinases, LLP1...

A new technique is developed for displaying disjoint convex polyhedra. The method has the following properties: It is output-sensitive, displays the objects in scanline mode, and it is naturally robust. There is no complex data structure uniting the different polyhedra, so dynamic insertions and deletions are simple. Its robustnes is based on a novel method of comparing depths by representative...
