Published: June 2006

AbstractWe describe a fetus with abnormal ultrasound (US) imaging at 20 weeks showing hydrocephalus and radial aplasia. Post‐mortem examination followed pregnancy termination and confirmed the diagnosis of oculo‐auriculo‐vertebral spectrum (OAVS). To delineate the pattern of prenatal features in OAVS, we reviewed 20 published fetuses showing abnormal US and/or magnetic resonance imaging. Gestational age at diagnosis ranged from 14 to 34–35 weeks. Cephalic abnormalities were found in only 52.4% (i.e., micro/anophthalmia, ear anomalies, hemifacial microsomia, and facial cleft). CNS defects occurred in 47.6% (i.e., hydrocephalus, occipital encephalocele, cerebellar hemisphere/vermis hypoplasia, and lipoma of the corpus callosum), together with abnormal amniotic fluid volume (AFV), either poly‐ or oligohydramnios. Nineteen percent had congenital heart disease, mainly atrioventricular septal defect. Hydroureteronephrosis, radial aplasia, lung, and kidney agenesis were additional findings. Recurrent patterns of anomalies included multiple asymmetric facial lesions (i.e., hemifacial microsomia, ipsilateral micro/anophthalmia, malformed ear) and CNS (particularly hydrocephalus) plus AFV abnormalities. In addition, prognosis of prenatally detected OAVS patients resulted more severe than generally observed in this condition. © 2006 Wiley‐Liss, Inc.

AbstractSynthesis of novel 4‐(4‐methylsulfonylphenyl)‐3‐phenyl‐2(3H)‐thiazole thione derivatives with functionalized diarylheterocycle pharmacophore as potential COX‐2 inhibitors was described. The title compounds were synth‐ esized by cyclocondensation of corresponding dithiocarbamate and 2‐bromo‐1‐(4‐methylsulfonylphenyl)ethanone, followed by dehydration with H2SO4. All of the target compounds were characterized by 1H NMR, IR and mass spectral data.
Domino Michael/Retro‐Michael/Mukaiyama‐Aldol Reactions of 1,3‐Bis‐Silyl Enol Ethers with 3‐Acyl‐ and 3‐Formylbenzopyrylium Triflates – Synthesis of Functionalised 2,4′‐Dihydroxybenzophenones
Authors: Appel Bettina , Rotzoll Sven , Kranich Remo , Reinke Helmut , Langer Peter 
Published: June 2006

AbstractThe reaction of 1,3‐bis‐silyl enol ethers with 3‐acyl‐ and 3‐formylbenzopyrylium triflates, which can be generated in situ from 3‐acyl‐ and 3‐formylchromones, affords a great variety of functionalised 2,4′‐dihydroxybenzophenones and 4‐(2‐hydroxybenzoyl)salicylates. These products are formed by a domino Michael/retro‐Michael/Mukaiyama‐aldol reaction. This methodology is successfully applied to the synthesis of novel UV‐A/B and UV‐B filters. Three 4‐(2‐hydroxybenzoyl)salicylic acids show a good in vitro activity in a selectin bioassay. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

Maximum pebbling number of graphs of diameter three
Authors: Bukh Boris 
Published: June 2006

AbstractGiven a configuration of pebbles on the vertices of a graph G, a pebbling move consists of taking two pebbles off some vertex v and putting one of them back on a vertex adjacent to v. A graph is called pebbleable if for each vertex v there is a sequence of pebbling moves that would place at least one pebble on v. The pebbling number of a graph G is the smallest integer m such that G is pebbleable for every configuration of m pebbles on G. We prove that the pebbling number of a graph of diameter 3 on n vertices is no more than (3/2)n + O(1), and, by explicit construction, that the bound is sharp. © 2006 Wiley Periodicals, Inc.

α‐Glucan phosphorylase and its use in carbohydrate engineering
Authors: Yanase Michiyo , Takaha Takeshi , Kuriki Takashi 
Published: June 2006

AbstractAmylose is expected to be a functional biomaterial for various industries but is not produced on an industrial scale, since the purification of natural amylose from starch is difficult. The authors have recently established a system to produce synthetic amylose from either sucrose or cellobiose using the combined action of α‐glucan phosphorylase (EC 2.4.1.1) together with sucrose phosphorylase (EC 2.4.1.7) or cellobiose phosphorylase (EC 2.4.1.20). In these combined enzymic systems, α‐glucan phosphorylase is a key enzyme. This paper summarises the authors' work to engineer practical α‐glucan phosphorylase for industrial processes and its use in the enzymatic synthesis of essentially linear amylose and other glucose polymers.

Differential operators and boundary value problems on hypersurfaces
Authors: Duduchava L. Roland , Mitrea Dorina , Mitrea Marius 
Published: June 2006

AbstractWe explore the extent to which basic differential operators (such as Laplace–Beltrami, Lamé, Navier–Stokes, etc.) and boundary value problems on a hypersurface 𝒮 in ℝn can be expressed globally, in terms of the standard spatial coordinates in ℝn . The approach we develop also provides, in some important cases, useful simplifications as well as new interpretations of classical operators and equations. (© 2006 WILEY‐VCH Verlag GmbH & Co.

When a lattice homomorphism is a Riesz homomorphism
Authors: Ercan Z. , Wickstead A.W. 
Published: June 2006

AbstractLet E and F be uniformly complete vector lattices with disjoint complete systems (ui )i ∈I and (vi )i ∈I of projection elements of E and F respectively. In this paper we prove that if T is a lattice homomorphism from E into F with T (λui ) = λvi for each λ ∈ ℝ and i ∈ I then T is linear. This generalizes the main results of [4] and [5].

Littlewood–Paley decompositions and Besov spaces on Lie groups of polynomial growth
Authors: Furioli G. , Melzi C. , Veneruso A. 
Published: June 2006

AbstractWe introduce a Littlewood–Paley decomposition related to any sub‐Laplacian on a Lie group G of polynomial volume growth; this allows us to prove a Littlewood–Paley theorem in this general setting and to provide a dyadic characterization of Besov spaces B s,q p (G ), s ∈ ℝ, equivalent to the classical definition through the heat kernel.

Equivalence of AMLE, strong AMLE, and comparison with cones in metric measure spaces
Authors: Juutinen Petri , Shanmugalingam Nageswari 
Published: June 2006

AbstractIn this paper, we study the relationship between p ‐harmonic functions and absolutely minimizing Lipschitz extensions in the setting of a metric measure space (X, d, μ ). In particular, we show that limits of p ‐harmonic functions (as p → ∞) are necessarily the∞ ‐energy minimizers among the class of all Lipschitz functions with the same boundary data. Our research is motivated by the observation that while the p ‐harmonic functions in general depend on the underlying measure μ , in many cases their asymptotic limit as p → ∞ turns out have a characterization that is independent of the measure.

The approach‐dependent, time‐dependent, label‐constrained shortest path problem
Authors: Sherali Hanif D. , Jeenanunta Chawalit , Hobeika Antoine G. 
Published: June 2006

AbstractIn this article, we consider an approach‐dependent, time‐dependent, label‐constrained shortest path problem. This is a variant of the shortest path problem defined on a transportation network comprised of a set of nodes and a set of directed arcs such that each arc has an associated label designating a mode of transportation, and an associated travel‐time function that depends on the time of arrival at the tail node, as well as on the link via which this node was approached. A label constraint is specified that controls the admissible sequence of transportation modes, and the approach‐dependent travel‐time feature models turn‐penalties and prohibitions in transportation networks, whereby the time spent at an intersection before entering the next link depends on whether we travel straight through the intersection, or make a right turn at it, or make a left turn at it, as permissible. We propose two effective algorithms to solve this problem and present related theoretical complexity results. In addition, we also explore various heuristic delay estimation and network curtailment schemes that can be used to confine the search to only the more promising subsets of the network to reduce computational effort while preserving near‐optimality. Extensive empirical results using available data for the Portland, OR, and Blacksburg, VA, transportation networks are presented to demonstrate the efficacy of the developed procedures. © 2006 Wiley Periodicals, Inc.

Published: June 2006

AbstractBackgroundEuropean Surveillance of Congenital Anomalies (EUROCAT) is a network of population‐based congenital anomaly registries in Europe surveying more than 1 million births per year, or 25% of the births in the European Union. This paper describes the potential of the EUROCAT collaboration for pharmacoepidemiology and drug safety surveillance.MethodsThe 34 full members and 6 associate members of the EUROCAT network were sent a questionnaire about their data sources on drug exposure and on drug coding. Available data on drug exposure during the first trimester available in the central EUROCAT database for the years 1996–2000 was summarised for 15 out of 25 responding full members.ResultsOf the 40 registries, 29 returned questionnaires (25 full and 4 associate members). Four of these registries do not collect data on maternal drug use. Of the full members, 15 registries use the EUROCAT drug code, 4 use the international ATC drug code, 3 registries use another coding system and 7 use a combination of these coding systems. Obstetric records are the most frequently used sources of drug information for the registries, followed by interviews with the mother. Only one registry uses pharmacy data. Percentages of cases with drug exposure (excluding vitamins/minerals) varied from 4.4% to 26.0% among different registries. The categories of drugs recorded varied widely between registries.ConclusionsPractices vary widely between registries regarding recording drug exposure information. EUROCAT has the potential to be an effective collaborative framework to contribute to post‐marketing drug surveillance in relation to teratogenic effects, but work is needed to implement ATC drug coding more widely, and to diversify the sources of information used to determine drug exposure in each registry.
