Building Better Environmental Risk Assessments.

Frontiers in bioengineering and biotechnology

Layton R, Smith J, Macdonald P, Letchumanan R, Keese P, Lema M.
PMID: 26301217
Front Bioeng Biotechnol. 2015 Aug 06;3:110. doi: 10.3389/fbioe.2015.00110. eCollection 2015.

Risk assessment is a reasoned, structured approach to address uncertainty based on scientific and technical evidence. It forms the foundation for regulatory decision-making, which is bound by legislative and policy requirements, as well as the need for making timely...

Highly regioselective synthesis of 4-tosylthiomorpholine via intramolecular cyclization of N-tethered thioalkenols.

Organic & biomolecular chemistry

Saikia AK, Deka MJ, Borthakur U.
PMID: 27762410
Org Biomol Chem. 2016 Nov 08;14(44):10489-10495. doi: 10.1039/c6ob01869f.

A one-pot, metal-free procedure has been developed for the synthesis of 4-tosylthiomorpholine from N-tethered thioalkenols via bromination, cyclization and subsequent elimination reaction in good yields. The reaction is found to be highly regioselective.

Cyclodextrin-polysaccharide-based, in situ-gelled system for ocular antifungal delivery.

Beilstein journal of organic chemistry

Fernández-Ferreiro A, Fernández Bargiela N, Varela MS, Martínez MG, Pardo M, Piñeiro Ces A, Méndez JB, Barcia MG, Lamas MJ, Otero-Espinar F.
PMID: 25550757
Beilstein J Org Chem. 2014 Dec 08;10:2903-11. doi: 10.3762/bjoc.10.308. eCollection 2014.

Fluconazole was studied with two different hydrophilic cyclodextrins (hydroxypropyl-β-cyclodextrin (HPBCD) and sulfobutyl ether-β-cyclodextrin (SBECD)) for the formation of inclusion complexes. HPBCD and SBECD showed low cell cytotoxicity in human keratocytes as assessed by the label-free xCELLigence system for real-time...

The DNA content of polytene nuclei in midgut and Malpighian tubule cells of adultDrosophila melanogaster.

Wilhelm Roux's archives of developmental biology

Lamb MJ.
PMID: 28305263
Wilehm Roux Arch Dev Biol. 1982 Nov;191(6):381-384. doi: 10.1007/BF00879628.

The amounts of DNA in midgut and Malpighian tubule cells of adult maleDrosophila melanogaster have been determined by Feulgen-DNA cytophotometry. The DNA values fall into discrete classes reflecting different levels of polyteny. The maximum level is 64C in the...

Tuning first molecular hyperpolarizabilities through the use of proaromatic spacers.

Journal of the American Chemical Society

Andreu R, Blesa MJ, Carrasquer L, Garín J, Orduna J, Villacampa B, Alcalá R, Casado J, Ruiz Delgado MC, López Navarrete JT, Allain M.
PMID: 15954792
J Am Chem Soc. 2005 Jun 22;127(24):8835-45. doi: 10.1021/ja051819l.

In this paper, we describe the second-order nonlinear optical properties of a series of 1,3-dithiole-based electron donor-acceptor systems incorporating proaromatic donor and spacer groups. Modification of the proaromaticity of the quinoid spacer gives rise to NLO-phores with mubeta values...

Tetrathiafulvalene in a perylene-3,4:9,10-bis(dicarboximide)-based dyad: a new reversible fluorescence-redox dependent molecular system.

The Journal of organic chemistry

Leroy-Lhez S, Baffreau J, Perrin L, Levillain E, Allain M, Blesa MJ, Hudhomme P.
PMID: 16050692
J Org Chem. 2005 Aug 05;70(16):6313-20. doi: 10.1021/jo050766n.

A donor-acceptor dyad system involving tetrathiafulvalene (TTF) as donor attached by a flexible spacer to perylene-3,4:9,10-bis(dicarboximide) (PDI) as acceptor was synthesized and characterized. The strategy used the preliminary synthesis of an unsymmetrical PDI unit bearing an alcohol functionality as...

Continuous production of manganese peroxidase by Phanerochaete chrysosporium immobilized on polyurethane foam in a pulsed packed-bed bioreactor.

Biotechnology and bioengineering

Moreira MT, Feijoo G, Palma C, Lema JM.
PMID: 18636618
Biotechnol Bioeng. 1997 Oct 20;56(2):130-7. doi: 10.1002/(SICI)1097-0290(19971020)56:2<130::AID-BIT2>3.0.CO;2-Q.

The bottleneck of the application of manganese peroxidase (MnP) on an industrial scale in pulp biobleaching or in degradation of hazardous compounds is the lack of an efficient production system. Three main problems arise for the continuous production of...

Spreading and infiltration of inkjet-printed polymer solution droplets on a porous substrate.

Journal of colloid and interface science

Holman RK, Cima MJ, Uhland SA, Sachs E.
