Epithelial topography for repetitive tooth formation.

Biology open

Gaete M, Fons JM, Popa EM, Chatzeli L, Tucker AS.
PMID: 26538639
Biol Open. 2015 Nov 04;4(12):1625-34. doi: 10.1242/bio.013672.

During the formation of repetitive ectodermally derived organs such as mammary glands, lateral line and teeth, the tissue primordium iteratively initiates new structures. In the case of successional molar development, new teeth appear sequentially in the posterior region of...

ChIP-less analysis of chromatin states.

Epigenetics & chromatin

Su Z, Boersma MD, Lee JH, Oliver SS, Liu S, Garcia BA, Denu JM.
PMID: 24872844
Epigenetics Chromatin. 2014 Apr 24;7:7. doi: 10.1186/1756-8935-7-7. eCollection 2014.

BACKGROUND: Histone post-translational modifications (PTMs) are key epigenetic regulators in chromatin-based processes. Increasing evidence suggests that vast combinations of PTMs exist within chromatin histones. These complex patterns, rather than individual PTMs, are thought to define functional chromatin states. However,...

Exploring the environmental drivers of waterfowl movement in arid landscapes using first-passage time analysis.

Movement ecology

Henry DA, Ament JM, Cumming GS.
PMID: 27042310
Mov Ecol. 2016 Apr 01;4:8. doi: 10.1186/s40462-016-0073-x. eCollection 2016.

BACKGROUND: The movement patterns of many southern African waterfowl are typified by nomadism, which is thought to be a response to unpredictable changes in resource distributions. Nomadism and the related movement choices that waterfowl make in arid environments are,...

Gene transcription and steviol glycoside accumulation in Stevia rebaudiana under polyethylene glycol-induced drought stress in greenhouse cultivation.

FEBS open bio

Hajihashemi S, Geuns JM.
PMID: 27642557
FEBS Open Bio. 2016 Aug 30;6(9):937-44. doi: 10.1002/2211-5463.12099. eCollection 2016 Sep.

Stevia rebaudiana is a sweet herb of the Astraceae family, which is cultivated for the natural sweeteners it contains. The aim of this study was to assess the effect of drought, simulated by the application of polyethylene glycol (5%,...

Modifications hemodynamiques durant la cœlioscopie: étude menée par bioimpédance électrique thoracique.

Canadian journal of anaesthesia = Journal canadien d'anesthesie

Torrielli R, Cesarini M, Winnock S, Cabiro C, Mene JM.
PMID: 27709531
Can J Anaesth. 1990 Jan;37(1):46-51. doi: 10.1007/BF03007483.

Au cours de 18 cœlioscopies chez des jeunes femmes A.S.A. status physique 1, les conséquences hémodynamiques du pneumopéritoine et de la position de Trendelenburg ont été évaluées par la méthode non invasive de bioimpédance électrique thoracique. L'index cardiaque chute...

Roles of mycobacterium tuberculosis ESAT-6 in the development of renal injury.

International journal of clinical and experimental medicine

Gao YT, Sun L, Feng JM.
PMID: 26885168
Int J Clin Exp Med. 2015 Nov 15;8(11):21964-74. eCollection 2015.

OBJECTIVE: The present study was designed to evaluate the role of mycobacterium tuberculosis early secretory antigen target-6 (MtbESAT-6) in the development of renal injury.METHODS: PET42a (+) ESAT6 prokaryotic expression plasmid was constructed and the purified ESAT6 protein without endotoxin...

Dehydrochlorination of alpha-Chlorophosphines, a Simple and General Route to Phosphaalkenes.

Inorganic chemistry

Gaumont AC, Pellerin B, Cabioch JL, Morise X, Lesvier M, Savignac P, Guenot P, Denis JM.
PMID: 11666827
Inorg Chem. 1996 Nov 06;35(23):6667-6675. doi: 10.1021/ic960417z.

Primary and secondary alpha-chlorophosphines 2a-g are prepared in ca. 70% yield by chemoselective reduction of the corresponding phosphonic and phosphinic esters with AlHCl(2) and are characterized by (31)P, (13)C, and (1)H NMR and by HMRS. They can be kept...

Manipulation of individual double-walled carbon nanotubes packed in a casing shell.

Nanotechnology

Wu S, Feng JM, Fu X, Hu XD, Dorantes D, Li YL, Hu XT.
PMID: 21646698
Nanotechnology. 2011 Jul 15;22(28):285308. doi: 10.1088/0957-4484/22/28/285308. Epub 2011 Jun 07.

Controlled placement of carbon nanotubes is important for carbon-based nanodevice assembly. However, it is difficult to manipulate individual nanotubes because of their extremely small dimensions. Ultra-fine tubes are often in the form of bundles and are hard to efficiently...

Pb(II) and Zn(II) adsorption onto Na- and Ca-montmorillonites in acetic acid/acetate medium: experimental approach and geochemical modeling.

Journal of colloid and interface science

Ghayaza M, Le Forestier L, Muller F, Tournassat C, Beny JM.
PMID: 21641613
J Colloid Interface Sci. 2011 Sep 01;361(1):238-46. doi: 10.1016/j.jcis.2011.05.028. Epub 2011 May 15.

Smectites are usually used as a clay barrier at the bottom of subsurface waste landfills due to their low permeability and their capacity to retain pollutants. The Na- and Ca-saturated SWy2 montmorillonites were interacted with initial Zn(NO(3))(2) or Pb(NO(3))(2)...

Structures and characterizations of bundles of collapsed double-walled carbon nanotubes.

Nanotechnology

Zhong XH, Wang R, Liu LB, Kang M, Wen YY, Hou F, Feng JM, Li YL.
PMID: 23196759
Nanotechnology. 2012 Dec 21;23(50):505712. doi: 10.1088/0957-4484/23/50/505712. Epub 2012 Nov 29.

The performance of carbon nanotube fibers (CNTFs) significantly depends on the packing styles of carbon nanotube (CNT) bundles. Revealing the structures and characterizations of CNT bundles is contributive to understanding the structures, properties and even the formation of CNTFs...

Winter Depression: Integrating mood, circadian rhythms, and the sleep/wake and light/dark cycles into a bio-psycho-social-environmental model.
