Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

Part I. Coenzyme B12 as a hydroformylation-type catalyst. Part II. Mechanisms of hydrogen transfer in the methylmalonyl coenzyme a mutase reaction

Part I

The mechanism of the hydroformylation reaction was studied. Using cobalt deuterotetracarbonyl and 1-pentene as substrates, the first step in the reaction, addition of cobalt tetracarbonyl to an olefin, was shown to be reversible.

Part II

The role of coenzyme B₁₂ in the isomerization of methylmalonyl coenzyme A to succinyl coenzyme A by methylmalonyl coenzyme A mutase was studied. The reaction was allowed to proceed to partial completion using a mixture of methylmalonyl coenzyme A and 4, 4, 4-tri-²H-methylmalonyl coenzyme A as substrate. The deuterium distribution in the product, succinyl coenzyme A, was shown to best fit a model in which hydrogen is transferred from C-4 of methylmalonyl coenzyme A to C-5’ of the adenosyl moiety of coenzyme B₁₂ in the rate determining step. The three hydrogens at the 5’-adenosyl position of the coenzyme B₁₂ intermediate are then able to become enzymatically equivalent before hydrogen is transferred from the coenzyme B₁₂ intermediate to form succinyl coenzyme A.

A Neural Theory of Attentive Visual Search: Interactions of Boundary, Surface, Spatial, and Object Representations

Visual search data are given a unified quantitative explanation by a model of how spatial maps in the parietal cortex and object recognition categories in the inferotemporal cortex deploy attentional resources as they reciprocally interact with visual representations in the prestriate cortex. The model visual representations arc organized into multiple boundary and surface representations. Visual search in the model is initiated by organizing multiple items that lie within a given boundary or surface representation into a candidate search grouping. These items arc compared with object recognition categories to test for matches or mismatches. Mismatches can trigger deeper searches and recursive selection of new groupings until a target object io identified. This search model is algorithmically specified to quantitatively simulate search data using a single set of parameters, as well as to qualitatively explain a still larger data base, including data of Aks and Enns (1992), Bravo and Blake (1990), Chellazzi, Miller, Duncan, and Desimone (1993), Egeth, Viri, and Garbart (1984), Cohen and Ivry (1991), Enno and Rensink (1990), He and Nakayarna (1992), Humphreys, Quinlan, and Riddoch (1989), Mordkoff, Yantis, and Egeth (1990), Nakayama and Silverman (1986), Treisman and Gelade (1980), Treisman and Sato (1990), Wolfe, Cave, and Franzel (1989), and Wolfe and Friedman-Hill (1992). The model hereby provides an alternative to recent variations on the Feature Integration and Guided Search models, and grounds the analysis of visual search in neural models of preattentive vision, attentive object learning and categorization, and attentive spatial localization and orientation.

3-D Object Recognition by the ART-EMAP Evidence Accumulation Network

ART-EMAP synthesizes adaptive resonance theory (AHT) and spatial and temporal evidence integration for dynamic predictive mapping (EMAP). The network extends the capabilities of fuzzy ARTMAP in four incremental stages. Stage I introduces distributed pattern representation at a view category field. Stage 2 adds a decision criterion to the mapping between view and object categories, delaying identification of ambiguous objects when faced with a low confidence prediction. Stage 3 augments the system with a field where evidence accumulates in medium-term memory (MTM). Stage 4 adds an unsupervised learning process to fine-tune performance after the limited initial period of supervised network training. Simulations of the four ART-EMAP stages demonstrate performance on a difficult 3-D object recognition problem.

Conception, synthèse et diversification de l'azaGly-Pro : un mime de tour beta, outil d'étude structure-activité : application au développement d'un nouvel agent tocolytique

Les accouchements prématurés constituent un problème médical majeur en constante augmentation et ce, malgré tous les efforts mis en œuvre afin de contrer le déclenchement des contractions avant terme. Cette thèse relate du ''design'' rationnel d'un nouvel agent thérapeutique (i.e., tocolytique) qui serait capable de 1) arrêter les contractions, et 2) prolonger la gestation. Pour ce faire, une nouvelle cible, la prostaglandine F2α et son récepteur ont été sélectionnés et le peptidomimétisme a été choisi afin de résoudre cette problématique. L'introduction contient un historique rapide de la conception à la synthèse (''drug design'') du peptide parent, le PDC113, premier peptide a avoir démontré des aptitudes tocolytiques suffisantes pour faire du peptidomimétisme. La deuxième partie de l'introduction présente les concepts du peptidomimétisme appliqués au PDC113 qui ont permis d'accéder au PDC113.824, inhibiteur allostérique du récepteur de la prostaglandine F2α, et explique comment ce mime nous a permis d'élucider les mécanismes de signalisation intracellulaire impliqués dans la contraction musculaire lisse. Cette thèse présente la conception, la synthèse et l'étude structure-activité de mimes de repliement de tour β au sein du mime peptidique original (PDC113.824) dans lequel nous avons remplacé l'azabicycloalkane central (l'indolizidin-2-one) par une série d'autres azabicycloalcanes connus et des acides aza-aminés dont nous avons élaboré la synthèse. Dans un premier temps, une nouvelle stratégie de synthèse en solution de l'aza-glycyl-proline à partir de la diphényle hydrazone et du chloroformate de p-nitrophényle a été réalisée. Cette stratégie a permis d'éliminer les réactions secondaires de cyclisation intramoléculaires communément obtenues lors de l'introduction d'acides aza-aminés avec les protections traditionnelles de type carbamate en présence de phosgène, mais aussi de faciliter l'accès en une étape à des dérivés peptidiques du type aza-glycyle. L'élongation de l'aza-glycyl-proline en solution nous a permis d'accéder à un nouveau mime tetrapeptidique du Smac, un activateur potentiel de l'apoptose au sein de cellules cancéreuses. Par la suite, nous avons développé une stratégie de diversification sélective de l'azote α du résidu azaglycine en utilisant différents types d'halogénures d'alkyle en présence de tert-butoxyde de potassium. Afin de valider le protocole d'alkylation de l'aza-dipeptide, différents halogénures d'alkyle ont été testés. Nous avons également démontré l'utilité des aza-dipeptides résultants en tant que ''building block'' afin d'accéder à une variété d'azapeptides. En effet, l'aza-dipeptide a été déprotégée sélectivement soit en N-terminal soit en C-terminal, respectivement. D'autre part, la libération de l'amine de l'ester méthylique de l'aza-alkylglycyl-proline a conduit à une catégorie de composés à potentiel thérapeutique, les azadicétopipérazines (aza-DKP) par cyclisation intramoléculaire. Enfin, notre intérêt quant au développement d'un nouvel agent tocolytique nous a amené à développer une nouvelle voie de synthèse en solution du PDC113.824 permettant ainsi d'élucider les voies de signalisation intracellulaires du récepteur de la prostaglandine F2α. Afin de valider l'importance de la stéréochimie et d'étudier la relation structure/ activité du mime, nous avons remplacé l'indolizidin-2-one (I2aa) centrale du PDC113.824 par une série d'autres azabicycloalcanes et azadipeptides. Les azabicycloalcanes D-I2aa, quinolizidinone, et indolizidin-9-one ont été synthétisés et incorporés au sein du dit peptide ne donnant aucune activité ni in vitro ni ex vivo, validant ainsi l'importance du tour β de type II' pour le maintien de l'activité biologique du PDC113.824. Finalement, l'insertion d'une série de dérivés aza(alkyl)glycyl-prolyles a mené à de nouveaux inhibiteurs allostériques du récepteur de la PGF2α, l'un contenant l'azaglycine et l'autre, l'azaphénylalanine. Cette thèse a ainsi contribué, grâce à la conception et l'application de nouvelles méthodes de synthèse d'aza-peptides, au développement de nouveaux composés à potentiel thérapeutique afin d'inhiber le travail prématuré.

A Review on the Challenges for Increased Production of Castor

Castor (Ricinus communis L.) is one of the oldest cultivated crops, but currently it represents only 0.15% of the vegetable oil produced in the world. Castor oil is of continuing importance to the global specialty chemical industry because it is the only commercial source of a hydroxylated fatty acid. Castor also has tremendous future potential as an industrial oilseed crop because of its high seed oil content (more than 480 g kg(-1)), unique fatty acid composition (900 g kg(-1) of ricinoleic acid), potentially high oil yields (1250-2500 L ha(-1)), and ability to be grown under drought and saline conditions. The scientific literature on castor has been generated by a relatively small global community of researchers over the past century. Much of this work was published in dozens of languages in journals that are not easily accessible to the scientific community. This review was conducted to provide a compilation of the most relevant historic research information and define the tremendous future potential of castor. The article was prepared by a group of 22 scientists from 16 institutions and eight countries. Topics discussed in this review include: (i) germplasm, genetics, breeding, biotic stresses, genome sequencing, and biotechnology; (ii) agronomic production practices, diseases, and abiotic stresses; (iii) management and reduction of toxins for the use of castor meal as both an animal feed and an organic fertilizer; (iv) future industrial uses of castor including renewable fuels; (v) world production, consumption, and prices; and (vi) potential and challenges for increased castor production.

Transthoracic cardiac ultrasonic stimulation induces a negative chronotropic effect

The objective of this study is to investigate cardiac bioeffects resulting from ultrasonic stimulation using a specific set of acoustical parameters. Ten Sprague-Dawley rats were anesthetized and exposed to 1-MHz ultrasound pulses of 3-MPa peak rarefactional pressure and approximately 1% duty factor. The pulse repetition frequency started slightly above the heart rate and was decreased by 1 Hz every 10 s, for a total exposure duration of 30 s. The control group was composed of five rats. Two-way analysis of variance for repeated measures and Bonferroni post hoc tests were used to compare heart rate and ejection fraction, which was used as an index of myocardial contractility. It was demonstrated for the first time that transthoracic ultrasound has the potential to decrease the heart rate by similar to 20%. The negative chronotropic effect lasted for at least 15 min after ultrasound exposure and there was no apparent gross damage to the cardiac tissue.
