Birth defects interstate data exchange: A battle worth fighting?
Authors: Cassell Cynthia , Mai Cara , Rickard Russel 
Published: November 2007

AbstractBACKGROUND:Regardless of where infants and children are delivered, diagnosed, or treated, an important aspect of population‐based birth defects surveillance is ensuring the inclusion of children with birth defects in the catchment area. However, little is known as to how the lack of interstate birth defects data exchange affects program surveillance, monitoring, prevention, and referral activities. The study objectives were to determine the status of interstate birth defects data exchange agreements and to quantify statewide data on resident births occurring in nonresident states.METHODS:In 2004, surveys were distributed to all population‐based birth defects programs in the United States to determine: 1) the types of interstate birth defects data exchange agreements that exist among birth defects programs, 2) perceived barriers in establishing exchange agreements, and 3) the extent to which out‐of‐state births affect a program's catchment area. The National Center for Health Statistics (NCHS) data for 2002 on live birth residency were used to determine the actual frequency of out‐of‐state live birth occurrence.RESULTS:Of the 52 states and territories that were surveyed, 65% (n = 34) responded. Approximately 21% (n = 7) of those that responded had an interstate data exchange agreement that allowed sharing of birth defects data with another state or a facility within another state. Approximately 53% (n = 18) of responding states indicated plans to develop an interstate birth defects data exchange agreement with other states, hospitals, or both. The NCHS data showed that the actual percentage of resident out‐of‐state live births ranged from 0.16 to 11.51. NCHS data also reveal that 78% of states would be able to capture >75% of their out‐of‐state births by sharing data on out‐of‐state births with the three neighboring states ranking highest in terms of such occurrences.CONCLUSIONS:Few states have interstate birth defects data exchange agreements, though all states have resident births occurring out of state. While suggestive, data beyond residency of live births are needed to quantify the degree to which the objectives of state‐based birth defects programs are compromised. Resources exist to guide programs in establishing interstate data exchange agreements. Efforts to establish such agreements with only a few neighboring states could be a large step toward improving birth defects surveillance on a state, regional, and national level.

Zr‐TUD‐1: A Lewis Acidic, Three‐Dimensional, Mesoporous, Zirconium‐Containing Catalyst

Published: November 2007

AbstractA three‐dimensional, mesoporous, silicate containing zirconium, Zr‐TUD‐1, was synthesized by a direct hydrothermal treatment method with triethanolamine as a complexing and templating reagent to ensure that zirconium was incorporated as isolated atoms. The mesoporosity of Zr‐TUD‐1 was confirmed by X‐ray diffraction (XRD), N2 sorption and high‐resolution transmission electron micrograph (HR‐TEM) studies. The nature and strength of the Lewis acid sites present in Zr‐TUD‐1 were evaluated by FTIR studies of pyridine adsorption and temperature‐programmed desorption of ammonia. FTIR, X‐ray photoelectron spectroscopic (XPS) and UV/Vis spectroscopic studies showed that, at Si/Zr ratios of 25 and higher, all the zirconium was tetrahedrally incorporated into the mesoporous framework, while at low Si/Zr ratios, a small part of the zirconium was present as ZrO2 nanoparticles. Zr‐TUD‐1 is a Lewis acidic, stable and recyclable catalyst for the Meerwein–Ponndorf–Verley (MPV) reaction and for the Prins reaction.
A Gd3+‐Based Magnetic Resonance Imaging Contrast Agent Sensitive to β‐Galactosidase Activity Utilizing a Receptor‐Induced Magnetization Enhancement (RIME) Phenomenon

Published: November 2007

AbstractMagnetic resonance imaging (MRI) permits noninvasive three‐dimensional imaging of opaque organisms. Gadolinium (Gd3+) complexes have become important imaging tools as MRI contrast agents for MRI studies, though most of them are nonspecific and report solely on anatomy. Recently, MRI contrast agents have been reported whose ability to relax water protons is triggered or greatly enhanced by recognition of a particular biomolecule. This new class of MRI contrast agents could open up the possibility of reporting on the physiological state or metabolic activity deep within living specimens. One possible strategy for this purpose is to utilize the increase in the longitudinal water proton r1 relaxivity that occurs upon slowing the molecular rotation of a small paramagnetic complex, a phenomenon which is known as receptor‐induced magnetization enhancement (RIME), by either binding to a macromolecule or polymerization of the agent itself. Here we describe the design and synthesis of a novel β‐galactosidase‐activated MRI contrast agent, the Gd3+ complex [Gd‐5], by using the RIME approach. β‐Galactosidase is commonly used as a marker gene to monitor gene expression. This newly synthesized compound exhibited a 57 % increase in the r1 relaxivity in phosphate‐buffered saline (PBS) with 4.5 % w/v human serum albumin (HSA) in the presence of β‐galactosidase. Detailed investigations revealed that RIME is the dominant factor in this increase of the observed r1 relaxivity, based on analysis of Gd3+ complexes [Gd‐5] and [Gd‐8], which is generated from [Gd‐5] by the activity of β‐galactosidase, and spectroscopic analysis of their corresponding Tb3+ complexes, [Tb‐5] and [Tb‐8].
Environmentally Friendly Chemoselective Oxidation of Primary Aliphatic Amines by Using a Biomimetic Electrocatalytic System
Authors: Largeron Martine , Chiaroni Angèle , Fleury Maurice‐Bernard 
Published: November 2007

AbstractEnvironmentally friendly oxidation of primary aliphatic amines to imines has been successfully achieved, under metal‐free conditions, by the use of diverse electrogenerated o‐azaquinone mediators. High catalytic performance, together with high chemoselectivity, were observed with electron‐poor o‐azaquinone catalysts generated from 2‐aminoresorcinol derivatives. Similar to copper amine oxidase enzymes, these mediators exhibited lower reactivity toward α‐branched primary amines and no reactivity toward secondary amines. In the case of 3,4‐aminophenol derivatives lacking a 2‐hydroxy group, the generated o‐azaquinone species failed to catalyze the oxidation of the amine to the corresponding imine. Further mechanistic considerations allowed a rationalization of the crucial role of the 2‐hydroxy group in converting a catalytically inert species into a highly effective biomimetic catalyst.
Stable Silanetriols That Contain tert‐Alkoxy Groups: Versatile Precursors of Siloxane‐Based Nanomaterials
Authors: Suzuki Jumpei , Shimojima Atsushi , Fujimoto Yasuhiro , Kuroda Kazuyuki 
Published: November 2007

AbstractNovel tert‐alkoxysilanetriols (ROSi(OH)3, R=adamantyl and 3‐ethyl‐3‐pentyl) have been prepared from the corresponding tert‐alkoxytrichlorosilanes and successfully used as molecular building blocks to produce ordered siloxane‐based nanomaterials. Controlled hydrolysis of the alkoxytrichlorosilanes led to the formation of crystalline powders of alkoxysilanetriols that were stable under ambient conditions. Solid‐state polycondensation of the alkoxysilanetriols occurred upon heating, which led to the formation of ordered silica–organic nanocomposites with laminated morphologies. On the other hand, silylation of the tert‐alkoxysilanetriols with chlorotrimethoxysilane enabled us to synthesize well‐defined oligomeric alkoxysilanes (ROSi[OSi(OMe)3]3). Hydrolysis and polycondensation of these oligomers followed by acid treatment gave microporous silica with narrow pore size distributions. Thus, tert‐alkoxy groups serve not only as protecting groups of siloxane species to regulate hydrolysis and polycondensation, but also as templates to generate micropores thereby providing unique synthetic pathways for the design of ordered silica‐based materials.
Stereoselective Isomerisation of N‐Allyl Aziridines into Geometrically Stable Z Enamines by Using Rhodium Hydride Catalysis

Published: November 2007

AbstractIn the presence of rhodium(I) hydride catalysts, tertiary N‐allylamines are known to isomerise into E enamines. In contrast, we have recently found that N‐allylaziridines isomerise to form Z enamines. On the basis of literature data, the most likely mechanism of isomerisation would involve a rhodium hydride addition/β‐hydride elimination sequence. We show that the observed selectivity cannot be adequately explained by this pathway and is more consistent with initial CH‐activation followed by rearrangement to form a five‐membered cyclometallated rhodium intermediate. This intermediate subsequently undergoes reductive elimination to form a CH bond. The resulting geometrically stable Z enamines are useful building blocks for stereoselective synthesis.

AbstractBiologically important and structurally unique marine natural products avarone (1), avarol (2), neoavarone (3), neoavarol (4) and aureol (5), were efficiently synthesized in a unified manner starting from (+)‐5‐methyl‐Wieland–Miescher ketone 10. The synthesis involved the following crucial steps: i) Sequential BF3⋅Et2O‐induced rearrangement/cyclization reaction of 2 and 4 to produce 5 with complete stereoselectivity in high yield (2 → 5 and 4 → 5); ii) strategic salcomine oxidation of the phenolic compounds 6 and 8 to derive the corresponding quinones 1 and 3 (6 → 1 and 8 → 3); and iii) Birch reductive alkylation of 10 with bromide 11 to construct the requisite carbon framework 12 (10 + 11 → 12). An in vitro cytotoxicity assay of compounds 1–5 against human histiocytic lymphoma cells U937 determined the order of cytotoxic potency (3 > 1 > 5 > 2 > 4) and some novel aspects of structure‐activity relationships.
