Published: January 2007

AbstractBACKGROUND: Maternal exposure to flu or fever has been associated with increased risk for neural tube defects (NTDs); however, few studies have considered the effects of medications on the effects of flu or fever. We evaluated the effect of maternal flu or fever, medication use (antibiotics, antipyretics), and their joint effect on NTDs. METHODS: Data came from an ongoing population‐based case‐control study of infants with external malformations in northern China. The case group included 363 infants with NTDs identified between January 2003 and June 2005. Controls were 523 newborn infants without identified congenital anomalies matched by county, sex, maternal ethnic group, and the closest date of conception for infants with any major external malformation. Data were collected by a trained health worker through face‐to‐face interviews after delivery. RESULTS: NTD risks were significantly associated with maternal flu or fever (adjusted odds ratio [AOR] = 3.93, 95% CI: 2.48–6.23) and antipyretic use (AOR = 4.86, 95% CI: 1.33–17.78), but not with antibiotic use (AOR = 1.75, 95% CI: 0.91–3.38) after adjusting for potential confounders. NTD risk associated with maternal antipyretic use was markedly higher for anencephaly (AOR = 7.03, 95% CI: 1.70–29.04) than for spina bifida (AOR = 3.98, 95% CI: 0.95–16.74). Mothers with flu or fever who were also using antipyretics showed a markedly higher AOR for anencephaly (14.75 vs. 4.52), spina bifida (16.30 vs. 3.85), and all NTDs combined (13.91 vs. 4.04) than mothers with flu or fever who were not using antipyretics. Maternal antibiotics did not markedly change the effects of flu or fever on anencephaly (4.17 vs. 4.83), spina bifida (5.08 vs. 4.21), and all NTDs combined (5.05 vs. 4.29). CONCLUSIONS: Maternal flu or fever and antipyretic use during the periconceptional period increases the risk for NTDs. Maternal exposure to antipyretics together with flu or fever results in a markedly higher risk of NTDs than exposure to flu or fever alone.

Fmoc‐based solid‐phase synthesis of GPR54‐agonistic pentapeptide derivatives containing alkene‐ and fluoroalkene‐dipeptide isosteres
Authors: Tomita Kenji , Narumi Tetsuo , Niida Ayumu , Oishi Shinya , Ohno Hiroaki , Fujii Nobutaka 
Published: January 2007

AbstractFmoc‐protected Phe‐Gly‐type (Z)‐alkene dipeptide isostere (ADI) and (E)‐fluoroalkene dipeptide isostere (FADI) were synthesized and applied to Fmoc‐based solid‐phase peptide synthesis (SPPS). These cis‐peptide bond mimetics were introduced into a bioactive pentapeptide [H‐Amb‐Phe‐Gly‐Leu‐Arg‐Trp‐NH2; Amb = 4‐(aminomethyl) benzoic acid], which has potent GPR54 agonistic activity. The resulting pentapeptide derivatives showed low GPR54 agonistic activity, as compared with the parent peptide and (E)‐ADI‐containing derivative. This suggests that the trans‐amide conformer of Phe‐Gly peptide bond of the parent peptide would be significantly important for bioactivity. Contrary to our expectations, a (Z)‐FADI‐containing derivative exhibited essentially no activity, revealing the necessity of critical validation of FADI‐bioisosterism. © 2007 Wiley Periodicals, Inc.

Leptin acts as a mitogenic and antiapoptotic factor for colonic cancer cells
Authors: Hoda M R , Keely S J , Bertelsen L S , Junger W G , Dharmasena D , Barrett K E 
Published: January 2007

Abstract

Background
Obesity is associated with increased levels of leptin. The mitogenic actions of leptin have been identified in various cell types. Because obesity may be a risk factor for colonic cancer, the proliferative and antiapoptotic effects of leptin on colonic cancer cells and the role of mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3-K) signalling were investigated.

Methods
Three human colonic cancer cell lines (T84, HT29/Cl.19A and Caco-2) were treated with leptin. Cell proliferation was measured using the XTT® colorimetric assay and apoptosis by a cell death enzyme-linked immunosorbent assay. Inhibitors of MAPK and PI3-K were used to evaluate the role of these signalling pathways. Phosphorylation of the downstream components extracellular signal-regulated kinase (ERK) 1/2 and Akt was detected by western blotting.

Results
Leptin increased cell number in all cell lines in a dose-dependent manner and reduced the number of apoptotic cells in a cell line-dependent manner. Leptin also caused ERK1/2 and Akt phosphorylation. Pretreatment with inhibitors of MAPK and PI3-K inhibited these responses, attenuated the mitogenic action of leptin and abolished its antiapoptotic effects.

Conclusion
Chronic increases in leptin concentration may enhance the growth of colonic cancers via MAPK and PI3-K pathways. These effects of leptin could provide a link between obesity and colonic cancer, and may represent a target for anticancer drug development.
Development of a Microreactor for Amino Acid Polymerization
Authors: Miyazaki M. , Honda T. , Nakamura H. , Maeda H. 
Published: January 2007

AbstractA microreaction system consisting of a micromixer and a capillary reaction component was developed for the continuous production of amino acid polymers. A silicon glass based chip‐type micromixer tethered with a three dimensional microchannel network was fabricated by a combination of maskless technique, dry‐etching, and sequential anode bonding. The microreactor was constructed by connecting the micromixer with a microcapillary reaction component and a syringe pump. The resulting microreactor showed excellent controllability of molecular weight distribution of polyamino acid synthesis. The microreactor also produced amino acid copolymers with a more highly controlled molecular weight distribution than that of a batchwise reaction system operating for two months. These features demonstrate that the new microreactor is extremely suitable for the production of polyamino acids.
Controlled Hydrogen Oxidation in a Microstructured Mixer‐Reactor Module
Authors: Görke O. , Pfeifer P. , Schubert K. 
Published: January 2007

AbstractFor different applications it is necessary to perform a controlled oxidation of hydrogen. Apart from the safety‐relevant aspect, it can be also necessary to utilize as much heat as possible. The experimental results showed that hot spots and therefore thermal stress can be avoided with this new reactor concept. In addition, it has been demonstrated, that a cold‐start of such microstructured components is quick and stationary conditions are reached within less than 10 minutes in dependence of the reaction parameters. Conversions of hydrogen were in the range of 98 % when stoechiometric conditions or oxygen excess were applied. The temperature gradients and heat losses in the stationary mode of the operation of such catalytic burners were depending on the flow directions and parameters.
CO‐Bond Cleavage of Esters with a Naphthyl Group in the Higher Triplet Excited State during Two‐Color Two‐Laser Flash Photolysis

Published: January 2007

AbstractA CO‐bond cleavage of esters having a naphthyl group, NpCO‐OR and RCO‐ONp (Np=α‐ and β‐naphthyl (αNp and βNp, respectively), R=Ph and Me), was found during the two‐color two‐laser flash photolysis in acetonitrile. The CO‐bond cleavage occurred when NpCO‐OR and RCO‐ONp were excited to the singlet excited states (S1). On the other hand, no reaction occurred from the lowest triplet excited states (T1). When NpCO‐OR(T1) and RCO‐ONp(T1) were excited to the higher triplet excited states (Tn) using the second laser during the two‐color two‐laser flash photolysis, the CO‐bond cleavage occurred. The CO‐bond cleavage quantum yield (Φ) was estimated from the plots of the T1‐state esters disappeared within a laser flash versus the second laser intensities. The CO‐bond cleavage in βNpCO‐OPh(Tn) occurred more efficiently than in αNpCO‐OPh(Tn) and that in PhCO‐OβNp(Tn) occurred more efficiently than in PhCO‐OαNp(Tn). The Φ value for ester with Ph and β‐Np groups was larger than that for ester with Ph and α‐Np groups. The Φ value for MeCO‐OαNp(Tn) was similar to those for PhCO‐ONp(Tn), while that for MeCO‐OβNp(Tn) was much smaller than those for PhCO‐ONp(Tn) and MeCO‐OαNp(Tn). On the other hand, no CO‐bond cleavage was observed in NpCO‐OMe(Tn). The Φ value depended on the characters of the groups (Np, Ph, and Me) on the ester. Whether R is Ph or Me with or without π electron, respectively, is important for the CO‐bond cleavage. In other words, electronic delocalization of the Tn state including Np and ester groups is necessary for the occurrence of the CO‐bond cleavage in NpCO‐OR(Tn) and RCO‐ONp(Tn).
Dipyrrolyl‐Functionalized Bipyridine‐Based Anion Receptors for Emission‐Based Selective Detection of Dihydrogen Phosphate

Published: January 2007

AbstractNew cationic anion receptors, based on the use of pyrrole‐substituted bipyridine and coordinated to transition metals, are described. Specifically, polypyridine–ruthenium and –rhodium cores have been functionalized to generate an anion binding site. The design was chosen to probe the influence of the pyrrole‐to‐pyrrole separation on anion‐binding affinities and selectivities; this distance is greater in the new systems of this report (receptors 1 and 2) relative to that present in related dipyrrolyl quinoxaline based receptors 3 and 4. Solution‐phase anion‐binding studies, carried out by means of 1H NMR spectroscopic titrations in [D6]DMSO and isothermal titration calorimetry (ITC) in DMSO, reveal that 1 and 2 bind most simple anions with substantially higher affinity than either 3 or 4. In the case of chloride anion, structural studies, carried out by means of single‐crystal X‐ray diffraction analyses, are consistent with the solution‐phase results and reveal that receptors 1 and 2 are both able to stabilize complexes with this halide anion in the solid state.
