11.000.000 de km2 pour quoi faire? Le cas de la Nouvelle-Calédonie. Synthèse et perspectives en termes de forme et de degré de protection des milieux naturels marins ArchiMer
Loubersac, Lionel.
This text, published in the magazine “Challenge. Le magazine du Pacifique” deals with the quite unique Caledonian case as far as its maritime character is concerned and is part of a related research programme of the French Institute for the Sea (IFM) on the issue: “11.000.000 square kilometres, what for?” To better address this question, an analysis grid sets the stage with regard to six main issues: legal status; parties involved; characteristics of natural habitats; safety and hazards; patterns of development and operational procedures; protection policies and tools. We deal below with the basic elements relative to the sixth of these points: policies and tools of the environmental protection in New Caledonia. Il reminds the history gradually established...

1-MCP efficiency in quality of ornamental peppers Horticultura Brasileira
Ribeiro,Wellington S; Carneiro,Clebson dos S; França,Christiane de Fátima M; Pinto,Cleide Maria F; Lima,Paula Cristina C; Finger,Fernando L.
ABSTRACT 1-MCP has been effectively used as an antagonist of ethylene deleterious actions in flowers and ornamental plants. The objective was to evaluate the efficiency of 1-MCP (0.0, 0.5, 1.0 and 1.5 g m-3) in maintaining post-production quality of exogenous ethylene sensitive ornamental pepper. Two commercial varieties were evaluated: Pimenta Colorida and Pimentão Ornamental, both Capsicum annuum. The pre-treatment with 1-MCP, regardless of the applied concentration, was effective in blocking the ethylene action reducing the leaves abscission, flowers and fruits of both genotypes by 100%. Plants pretreated with 1-MCP had postproduction life increased by eight and nine days for Pimenta Colorida and Pimentão Ornamental, respectively. The 1-MCP application...

2- Isopentenyladenine in the induction of direct somatic embryogenesis capacity of Coffea arabica L. Ciência Rural
Alves,Ivanilda dos Santos; Carmazini,Valéria Cristina Barbosa; Santos,Cosme Damião dos; Almeida,Julieta Andrea Silva de.
ABSTRACT: This study evaluated the effect of different concentrations of 2-isopentenyladenine (2-iP) on the direct somatic embryogenesis capacity of the Mundo Novo cultivar of Coffea arabica. Leaf explants were cultivated with half the MS salt concentration and the addition of sucrose (20gL-1) and 2-iP (0; 2.5; 5; 7.5 and 10µM). The 2-iP doses of 7.5 and 10µM produced the greatest responses with respect to the percentage of explants with embryogenic structures and the size of the embryogenic structures. However, the greatest production of somatic embryos occurred on the explants treated with 10µM of 2-iP, followed by 7.5µM, whereas their production was absent or reduced with 0 and 5µM, respectively.

2,3,8-Trisubstituted Quinolines with Antimalarial Activity Anais da ABC (AABC)
MARTINEZ,PABLO D.G.; KRAKE,SUSANN H.; POGGI,MAITIA L.; CAMPBELL,SIMON F.; WILLIS,PAUL A.; DIAS,LUIZ C..
ABSTRACT Combination therapy drugs are considered a fundamental way to control malaria as it mimimizes the risk of emergence of resistance to the individual partner drugs. Consequently, this type of therapy constitutes a driving force for the discovery of new drugs with different modes of action, since this will provide options for combining different drugs to achieve the optimum antimalarial treatment. In this context, a 2,3,8-trisubstitued quinoline compound was found in a high throughput screen (HTS) to show an excellent inhibition of P. falciparum NF54 (IC50 = 22 nM) and low cytotoxicity. We performed a detailed evaluation of the substituents to improve the metabolic stability and solubility liabilities of the original hit and identified derivatives...

2-Methyl 2-butanol suppresses human retinoblastoma cells through cell cycle arrest and autophagy BJMBR
Li,Xiangyun; Zhu,Xiangxiang; Xu,Chong; Wu,Jianhua.
2-Methyl-2-butanol (MBT) is a chemical compound from the group of alcohols more specifically pentanols, which has shown an excellent anti-cancer activity in our previous study. However, its mechanism of action remains unclear. The present study was designed to investigate the anti-cancer effect of MBT on human retinoblastoma cells. The results showed that the use of MBT leads to HXO-RB44 cell death but is cytotoxic to normal cells at higher concentrations. It showed a dose- as well as a time-dependent inhibition of HXO-RB44 cells. P27 is a cell cycle inhibitory protein, which plays an important role in cell cycle regulation whereas cyclin-B1 is a regulatory protein involved in mitosis. MBT increased the cell cycle arrest in a dose-dependent manner by...

30 years of research on insect galls in Brazil: a scientometric review Pap. Avulsos de Zool. (São Paulo)
Araújo,Walter Santos de.
Abstract The first systematic studies on insect galls in Brazil date to the early 20th century, after which research on insect galls remained dormant in the country, with interest not reviving until the 1980s. The aim of this study was is to document historical trends in publications about insect galls in Brazil over the last 30 years. Papers about insect galls and galling species in Brazil published in peer-reviewed journals from 1988 to 2017 were compiled. A total of 1,378 papers were analyzed, of which 182 addressed insect galls in Brazil. The results showed that the number of publications on the subject has been increasing over the last 30 years, and especially in the last decade. The diversity of journals that published on the subject has also been...

3D Dense Reconstruction of Plant or Tree Canopy Based on Stereo Vision CIGR Journal
Ni, Zhijiang; Burks, Thomas F..
Three dimensional (3D) reconstruction of the plant or tree canopy is an important step in order to measure canopy geometry, such as, height, width, volume, and leaf cover area. In this research, binocular stereo vision was used to recover the 3D information of the canopy. A revised camera calibration method was provided to calibrate the cameras in world coordinate system. Only two images were used to realize a dense reconstruction. These two images were firstly rectified to make sure the corresponding feature points in the left and right images were on the same horizontal line. An efficient large scale stereo matching (ELAS) algorithm was used to find the disparity map. The plant or tree canopy was finally reconstructed based on these calibrated camera...

3D-printed lab-on-valve for fluorescent determination of cadmium and lead in water ArchiMer
Mattio, Elodie; Robert-peillard, Fabien; Vassalo, Laurent; Branger, Catherine; Margaillan, Andre; Brach-papa, Christophe; Knoery, Joel; Boudenne, Jean-luc; Coulomb, Bruno.
In recent years, the development of 3D printing in flow analysis has allowed the creation of new systems with various applications. Up to now, 3D printing was mainly used for the manufacture of small units such as flow detection cells, preconcentration units or mixing systems. In the present study, a new 3D printed lab-on-valve system was developed to selectively quantify lead and cadmium in water. Different technologies were compared for lab-on-valve 3D printing. Printed test units have shown that stereolithography or digital light processing are satisfactory techniques for creating complex lab-on-valve units. The lab-on-valve system was composed of two columns, eight peripheral ports and a central port, and a coil integrating baffles to increase mixing...

4-Phenyl-1,3-thiazole-2-amines as scaffolds for new antileishmanial agents J. Venom. Anim. Toxins incl. Trop. Dis.
Rodrigues,Carina Agostinho; Santos,Paloma Freire dos; Costa,Marcela Oliveira Legramanti da; Pavani,Thais Fernanda Amorim; Xander,Patrícia; Geraldo,Mariana Marques; Mengarda,Ana; Moraes,Josué de; Rando,Daniela Gonçales Galasse.
Abstract Background: There is still a need for new alternatives in pharmacological therapy for neglected diseases, as the drugs available show high toxicity and parenteral administration. That is the case for the treatment of leishmaniasis, particularly to the cutaneous clinical form of the disease. In this study, we present the synthesis and biological screening of eight 4-phenyl-1,3-thiazol-2-amines assayed against Leishmania amazonensis. Herein we propose that these compounds are good starting points for the search of new antileishmanial drugs by demonstrating some of the structural aspects which could interfere with the observed activity, as well as suggesting potential macromolecular targets. Methods: The compounds were easily synthesized by the...

6 weeks consumption of pure fresh coconut milk caused up-regulation of eNOS and CSE protein expression in middle-aged male rats BJPS
Jansakul,Chaweewan; Naphatthalung,Jomkarn; Pradab,Sakda; Yorsin,Somruedee; Kanokwiroon,Kanyanatt.
Coconut milk (CCM) has been an important cooking ingredient in the Asia-Pacific region since ancient time. Due to its high content of saturated fatty acids, it has been considered atherogenic. We have tested if chronic consumption of fresh coconut milk by middle-aged male rat affects vascular function, plasma glucose and lipid profiles. Compared to control, CCM caused lower maximal contraction to phenylephrine of thoracic aortic rings and increased relaxation to acetylcholine that was abolished by N G-nitro-L-arginine (L-NA) or disruption of the endothelium. DL-propargylglycine caused slight increase in baseline tension of L-NA treated aortic rings of CCM-treated rats and produced higher contractile response of the aortic rings to low concentrations of...

A 3D study of the bubble sweep-down phenomenon around a 1/30 scale ship model ArchiMer
Mallat, Bachar; Germain, Gregory; Billard, Jean-yves; Gaurier, Benoit.
The bubble sweep-down phenomenon around oceanographic research vessels generates acoustic disturbances. A specific experimental protocol in a wave and current circulating tank is used to study this phenomenon around a 1/30 scale ship model in a configuration with current, waves and ship motions. 3D visualizations of the bubble clouds and Stereo-PIV (Particle Image Velocimetry) measurements results, both obtained in the bow vicinity of the ship model, are presented in this paper. The behaviour of the breaking wave with bubble generation is studied and the spatial evolution of the bubble clouds is investigated. It is demonstrated that the bubble cloud generation is mainly conditioned by the ascending vertical velocity of the flow near the bow. It is observed...
