Dynamic nonlinear focal shift in amplitude modulated moderately focused acoustic beams.

Ultrasonics

Jiménez N, Camarena F, González-Salido N.
PMID: 27939786
Ultrasonics. 2017 Mar;75:106-114. doi: 10.1016/j.ultras.2016.11.021. Epub 2016 Nov 28.

The phenomenon of the displacement of the position of the pressure, intensity and acoustic radiation force maxima along the axis of focused acoustic beams under increasing driving amplitudes (nonlinear focal shift) is studied for the case of a moderately...

Carotenoid metabolism during chloroplast to chromoplast transformation in Capsicum annuum fruit.

Planta

Camara B, Brangeon J.
PMID: 24301979
Planta. 1981 Apr;151(4):359-64. doi: 10.1007/BF00393291.

Lipid and carotenoid metabolism associated with the structural transformations of the plastids during the ripening of Capsicum annuum fruits were studied. The early ripening stage is characterized by chloroplasts with a typical grana-intergranal structure and a highly developed peripheral...

Some characteristics of terpenoid biosynthesis by leucoplasts of Citrofortunella mitis.

Planta

Gleizes M, Camara B, Walter J.
PMID: 24232851
Planta. 1987 Jan;170(1):138-40. doi: 10.1007/BF00392390.

The capacity of leucoplasts to synthesize monoterpene hydrocarbons has been further investigated by studying the synthesis of higher-terpene homologues. Isolated leucoplasts were unable to esterify chlorophyllides into chlorophylls and to synthesize carotenoids. In addition, the later steps of α-tocopherol...

Carotenoid biosynthesis: Isolation and characterization of a bifunctional enzyme catalyzing the synthesis of phytoene.

Proceedings of the National Academy of Sciences of the United States of America

Dogbo O, Laferriére A, D'Harlingue A, Camara B.
PMID: 16578835
Proc Natl Acad Sci U S A. 1988 Oct;85(19):7054-8. doi: 10.1073/pnas.85.19.7054.

Phytoene is the first C(40) intermediate in the biogenesis of carotenoids. It is formed by two enzyme activities, catalyzing (i) the coupling of two molecules of geranylgeranyl diphosphate to yield prephytoene diphosphate and (ii) the conversion of prephytoene diphosphate...

Terpenoid metabolism in plastids : sites of phytoene synthetase activity and synthesis in plant cells.

Plant physiology

Camara B.
PMID: 16663362
Plant Physiol. 1984 Jan;74(1):112-6. doi: 10.1104/pp.74.1.112.

The biosynthesis of phytoene from prephytoene pyrophosphate has been localized exclusively in the plastid compartment of ruptured protoplasts derived from Triticum leaves and Capsicum fruits.The phytoene synthetase activity in Triticum leaves deficient in plastid ribosomes was comparable to those...

Terpenoid Metabolism in Plastids : Isolation and Biochemical Characteristics of Capsicum annuum Chromoplasts.

Plant physiology

Camara B, Bardat F, Dogbo O, Brangeon J, Monéger R.
PMID: 16663194
Plant Physiol. 1983 Sep;73(1):94-9. doi: 10.1104/pp.73.1.94.

A technique for the isolation and the purification of Capsicum annum L. var. Yolo Wonder chromoplasts is described. The degree of purity of the isolated chromoplasts is greatly improved by the absence of MgCl(2) in the extraction medium and...

Group Composition of Guinea Baboons (Papio papio) at a Water Place Suggests a Fluid Social Organization.

International journal of primatology

Patzelt A, Zinner D, Fickenscher G, Diedhiou S, Camara B, Stahl D, Fischer J.
PMID: 21654901
Int J Primatol. 2011 Jun;32(3):652-668. doi: 10.1007/s10764-011-9493-z. Epub 2011 Feb 11.

Baboon social systems are among the most studied in primates. Solid knowledge of the hamadryas and savannah baboon systems has accumulated, leading to a dichotomic view of baboon social systems. Hamadryas baboons live in multilayered troops based on 1-male...

Approaching the quantum limit of a nanomechanical resonator.

Science (New York, N.Y.)

LaHaye MD, Buu O, Camarota B, Schwab KC.
PMID: 15064412
Science. 2004 Apr 02;304(5667):74-7. doi: 10.1126/science.1094419.

By coupling a single-electron transistor to a high-quality factor, 19.7-megahertz nanomechanical resonator, we demonstrate position detection approaching that set by the Heisenberg uncertainty principle limit. At millikelvin temperatures, position resolution a factor of 4.3 above the quantum limit is...

Prenylation and methylation reactions in phylloquinone (vitamin K1) synthesis in Capsicum annuum plastids.

Plant cell reports

Gaudillière JP, d'Harlingue A, Camara B, Monéger R.
PMID: 24253576
Plant Cell Rep. 1984 Dec;3(6):240-2. doi: 10.1007/BF00269302.

The biosynthesis of phylloquinone (vitamin K1) was examined using Capsicum fruit chloroplasts and chromoplasts (apparently phylloquinone free). In both cases, the synthesis of phylloquinone from α-naphthoquinone, dihydro-α-naphthoquinone, 1,4-dihydroxy-2-naphthoic acid (as precursors of the ring moiety) and (S)-adenosyl-L-methionine was achieved....

Demonstration and solubilization of S-adenosylmethionine: γ-tocopherol methyltransferase from Capsicum chromoplasts.

Plant cell reports

Camara B, d'Harlingue A.
PMID: 24253640
Plant Cell Rep. 1985 Feb;4(1):31-2. doi: 10.1007/BF00285499.

Through the use of Capsicum chromoplast membranes, we report for the first time the direct methylation of γ-tocopherol into α-tocopherol in the presence of S-adenosylmethionine. Furthermore the S-adenosylmethionine: γ-tocopherol methyltransferase activity has been solubilized. On a protein basis, the...
