Nocturnal substrate association of four coral reef fish groups (parrotfishes, surgeonfishes, groupers and butterflyfishes) in relation to substrate architectural characteristics
Authors: Nanami Atsushi 
Published: July 2024

Although numerous coral reef fish species utilize substrates with high structural complexities as habitats and refuge spaces, quantitative analysis of nocturnal fish substrate associations has not been sufficiently examined yet. The aims of the present study were to clarify the nocturnal substrate associations of 17 coral reef fish species (nine parrotfish, two surgeonfish, two grouper and four butterflyfish) in relation to substrate architectural characteristics. Substrate architectural characteristics were categorized into seven types: (1) eave-like space, (2) large inter-branch space, (3) overhang by protrusion of fine branching structure, (4) overhang by coarse structure, (5) uneven structure without large space or overhang, (6) flat and (7) macroalgae. Overall, fishes were primarily associated with three architectural characteristics (eave-like space, large inter-branch space and overhang by coarse structure). The main providers of these three architectural characteristics were tabular and corymbose Acropora, staghorn Acropora, and rock. Species-specific significant positive associations with particular architectural characteristics were found as follows. For the nine parrotfish species, Chlorurus microrhinos with large inter-branch space and overhang by coarse structure; Ch. spilurus with eave-like space and large inter-branch space; Hipposcarus longiceps with large inter-branch space; Scarus ghobban with overhang by coarse structure; five species (Scarus forsteni, S. niger, S. oviceps, S. rivulatus and S. schlegeli) with eave-like space. For the two surgeonfish species, Naso unicornis with overhang by coarse structure; N. lituratus with eave-like space. For the two grouper species, Plectropomus leopardus with eave-like space; Epinephelus ongus with overhang by coarse structure. For the four butterflyfish species, Chaetodon trifascialis with eave-like space and large inter-branch space; C. lunulatus and C. ephippium with large inter-branch space; C. auriga showed no significant associations with any architectural characteristics. Four species (Ch. microrhinos, H. longiceps, S. niger and N. unicornis) also showed clear variations in substrate associations among the different fish size classes. Since parrotfishes, surgeonfishes and groupers are main fisheries targets in coral reefs, conservation and restoration of coral species that provide eave-like space (tabular and corymbose Acropora) and large inter-branch space (staghorn Acropora) as well as hard substrates with coarse structure that provide overhang (rock) should be considered for effective fisheries management in coral reefs. For butterflyfishes, coral species that provide eave-like space (tabular Acropora) and large inter-branch space (staghorn Acropora) should also be conserved and restored for provision of sleeping sites.
Influence of Crack Inclination Angle and Thickness on Mode-Mixity Using FEM
Authors: Rani Nisha , Bisht Neeraj 
Published: July 2024

Mode mixity is common in fatigue growth problems to assess the integrity of components by obtaining the fracture parameters as stress intensity factor, T-stress, J-integrals etc. Present study aims to investigate the effects of fracture parameters in a modified Compact Tension (CT) specimen using finite element methods (FEM) with ANSYS 2022 software. Crack orientation angle (α) and thickness (t) have their effects on crack growth which affect the life of a mechanical component. With increasing the crack inclination angle (0°, 15°, 30°, 45° and 60°), an increase in mode III stress intensity factor is noticed while mode I showed a significant decrement. Pure mode I is notice at 0°. With further increase in the angle mode-mixity (mode I and mode III) is obtained. Also, with an increase in the thickness (8mm, 10mm and 12mm) of component there is a noticeable decrease in all modes of stress intensity factor. This mode-mixity play a crucial role in the cracked model of the specimen.
Retroviral Gene Expression Control in Primary Organoid Cultures
Authors: Koo Bon‐Kyoung , Sasselli Valentina , Clevers Hans 
Published: November 2013

AbstractIn this unit, we describe a protocol for regulated gene expression in primary endodermal organoid culture using retroviral vectors. The study of gene function in endodermal epithelia such as those lining the stomach, small intestine, and colon has so far mainly relied on the generation of transgenic mouse lines. Establishing such animal models is laborious, expensive, and time‐consuming. Ever‐expanding endodermal organoids, grown in an in vitro 3‐D epithelial culture system, faithfully recapitulate the in vivo counterpart and represent a sustainable alternative. Gene overexpression and knockdown can be achieved in organoids by retroviral transduction. The technique can also be applied to organoids derived from pre‐established mutant mouse lines or used in combination with chemical and biological inhibitors or activators. This method provides a novel, versatile tool for phenotypic analysis of endodermal epithelium in vitro. Curr. Protoc. Stem Cell Biol. 27:5A.6.1‐5A.6.8. © 2013 by John Wiley & Sons, Inc.

A high‐throughput assay for the determination of acyltransferase activity of lipase CAL‐A
Authors: Müller Janett , Fredrich Birte , Kohlmann Christina , Maksym Lukas , Bornscheuer Uwe T. 
Published: November 2013

Certain lipases such as Candida antarctica lipase A (CAL‐A) are known to possess acyltransferase activity, which allows ester synthesis even in the presence of water. Discovery of novel lipases and identification of lipase variants with improved acyltransferase activity is laborious using standard methods such as gas chromatography. To overcome this limitation, an enzyme cascade was established based on quantification of the alcohol consumed in fatty acid ester synthesis from plant oils. For this, an alcohol oxidase converts the remaining alcohol to the corresponding aldehyde with concomitant formation of hydrogen peroxide. This is then quantified by the action of horseradish peroxidase leading to the oxidation of the co‐substrate ABTS, which is determined spectrophotometrically at 695 nm. The conversions thus determined correspond well to data measured by off‐line gas chromatography analysis and the assay could be adapted to the microtiterplate format.Practical applications: Fatty acid esters are valuable compounds in various industrial applications, i.e., fatty acid methyl esters are used as biofuels and ethyl esters can serve as fragrance or flavoring compounds in the cosmetic industry. The enzymatic synthesis of these compounds is possible, but often enzymes need to be adapted to meet process requirements. This assay simplifies the identification of suitable enzymes. Moreover, substrate specificities of a lipase for a certain alcohol or acyl acceptor can also be easily studied with this assay.
Total Synthesis of Cercidinin A
Authors: Yamada Hidetoshi , Ohara Kenya , Ogura Takahito 
Published: November 2013

AbstractAn ellagitannin, cercidinin A, was synthesized through both intramolecular coupling of gallates on a glucose moiety and double esterification of protected hexahydroxydiphenic acid to a diol. The total synthesis confirmed the revised structure of cercidinin A as 1,2,6‐tri‐O‐galloyl‐3,4‐(R)‐hexahydroxydiphenoyl (HHDP) β‐D‐glucose. This is the first synthesis of 3,4‐HHDP‐bridged ellagitannins and was achieved after overcoming two challenges: (1) full galloylation of β‐glucose hindered the formation of the 3,4‐HHDP group, and (2) the fully benzylated galloyl group, which is a routine component in ellagitannin synthesis, was not always appropriate. The solutions to these problems can be used to form a strategy for the synthesis of complex ellagitannins.

AbstractDetection of the genotoxic impurity hydrazine (HZ) in the presence of active pharmaceutical ingredients (APIs) represents a significant challenge to the pharmaceutical industry. Here we show how the use of electrochemical strategies in conjunction with metal nanoparticle (NP) functionalised polycrystalline boron‐doped diamond (BDD) electrodes enables detection of HZ in the presence of two different electrochemically active APIs. By simply changing the chemical identity of the metal NP, which shifts the detection potential for HZ, it is possible to selectively screen out the API signature from the HZ current – voltage response. HZ detection limits of 11.1 µM (Au NP BDD) and 3.3 µM (Pt NP BDD) in the presence of excess acetaminophen and promazine respectively, were determined using differential pulse voltammetry in quiescent solution.
Evaluation of donor factors contributing to plateletpheresis yields among apheresis platelet donors
Authors: Woodall William J. , Nguyen Vinh Q. , Tran Minh‐Ha 
Published: November 2013

BackgroundThe University of California, Irvine Blood Donor Center operates a plateletpheresis donor program utilizing the Amicus Cell Separator. Plateletpheresis donors may donate one or more apheresis platelet (PLT) units per collection event. This study seeks to characterize UC Irvine's donor pool by identifying biometric and demographic attributes predictive of double product (DP) collections.Study Design and MethodsBiometric, demographic and procedural data from 1,786 apheresis donors were collected and entered into Excel spreadsheets. Of the 1,786 successful plateletpheresis procedures performed from January 2009 to April 2012, 1,442 of the donations were performed using double‐needle (DN) kits. Only data from DN‐kit collections were used for statistical analyses. The Classification And Regression Tree (CART) algorithm was used to help identify variables predictive of donating multiple PLT units in a single collection event.ResultsDonors weighing 75.7 kg or greater appear to be twice as likely to donate DPs as those weighing less than 75.7 kg. For donors weighing less than 75.7 kg, females appear to be twice as likely to donate DPs as males. Donors exhibiting platelet counts of 216.5 K/mcL or greater appear to be twice as likely to donate DPs as those with platelet counts fewer than 216.5 K/mcL.ConclusionWeight, sex, and PLT count were identified as the most predictive donor attributes that separate UCI donors into DP donors and non‐DP donors. Greater weights, greater PLT counts, and female sex confer to greater PLT yields per given amount of time. J. Clin. Apheresis 29:139–147, 2014. © 2013 Wiley Periodicals, Inc.
Reduction of motion artifacts in carotid MRI using free‐induction decay navigators
Authors: Dyverfeldt Petter , Deshpande Vibhas S. , Kober Tobias , Krueger Gunnar , Saloner David 
Published: November 2013

PurposeTo develop a framework for prospective free‐induction decay (FID)‐based navigator gating for suppression of motion artifacts in carotid magnetic resonance imaging (MRI) and to assess its capability in vivo.Materials and MethodsAn FID‐navigator, comprising a spatially selective low flip‐angle sinc‐pulse followed by an analog‐to‐digital converter (ADC) readout, was added to a conventional turbo spin‐echo (TSE) sequence. Real‐time navigator processing delivered accept/reject‐and‐reacquire decisions to the sequence. In this Institutional Review Board (IRB)‐approved study, seven volunteers were scanned with a 2D T2‐weighted TSE sequence. A reference scan with volunteers instructed to minimize motion as well as nongated and gated scans with volunteers instructed to perform different motion tasks were performed in each subject. Multiple image quality measures were employed to quantify the effect of gating.ResultsThere was no significant difference in lumen‐to‐wall sharpness (2.3 ± 0.3 vs. 2.3 ± 0.4), contrast‐to‐noise ratio (CNR) (9.0 ± 2.0 vs. 8.5 ± 2.0), or image quality score (3.1 ± 0.9 vs. 2.6 ± 1.2) between the reference and gated images. For images acquired during motion, all image quality measures were higher (P < 0.05) in the gated compared to nongated images (sharpness: 2.3 ± 0.4 vs. 1.8 ± 0.5, CNR: 8.5 ± 2.0 vs. 7.2 ± 2.0, score: 2.6 ± 1.2 vs. 1.8 ± 1.0).ConclusionArtifacts caused by the employed motion tasks deteriorated image quality in the nongated scans. These artifacts were alleviated with the proposed FID‐navigator. J. Magn. Reson. Imaging 2014;40:214–220. © 2013 Wiley Periodicals, Inc.

Objectives/HypothesisThe purpose of this study was to report on a series of 162 patients presenting with juvenile nasopharyngeal angiofibroma in a single academic hospital during the past 17 years, in an effort to compare outcomes between open and transnasal endoscopic approach, and to define an ideal treatment strategy.Study DesignPatients who received either open or endoscopic surgery with a minimum follow‐up of 6 months were selected. Local control and complications were compared between groups.MethodsRetrospectively, clinical data, surgical reports, pre‐ and postoperative images, and follow‐up information were reviewed and analyzed.ResultsAll patients were male subjects from 8 to 41 years old. Ninety‐six patients were treated by transpalatal or transmaxillary approach, and the remaining 66 patients were treated using transnasal endoscopic approach with/without labiogingival incision. When compared to the open surgery group, the endoscopic surgery group showed a lower median intraoperative blood loss (800 vs. 1100 mL, P = .017) and a lower number of postoperative complications (one vs. 10). In addition, recurrence statistically correlated with Radkowski's classification and patient age.ConclusionsTransnasal endoscopic approach can be successfully used for Radkowski's stages I‐IIb tumors and selective IIc‐IIIb lesions, allowing for less blood loss, fewer postoperative complications, and a lower percentage of recurrence in comparison to open surgery. The management of recurrent tumor is complex, should be individually tailored, and should take into account tumor location, patient age, complications of treatment, and the possibility of spontaneous involution, to better define treatment strategy.Level of Evidence4.

Emotional variability during mother–adolescent conflict interactions: Longitudinal links to adolescent disclosure and maternal control
Authors: Van der Giessen Daniëlle , Branje Susan , Keijsers Loes , Van Lier Pol A.C. , Koot Hans M. , Meeus Wim 
Published: November 2013

ABSTRACTThe aim of this study was to examine relations of emotional variability during mother–adolescent conflict interactions in early adolescence with adolescent disclosure and maternal control in early and late adolescence. Data were used from 92 mother–adolescent dyads (M age T1 = 13.05; 65.20% boys) that were videotaped at T1 while discussing a conflict. Emotional variability was derived from these conflict interactions. Mothers also completed questionnaires at the start of the study (T1) and five years later (T6) on adolescent disclosure and maternal control. Path analysis showed that more emotional variability during conflict interactions in early adolescence was associated with higher levels of adolescent disclosure in early adolescence and with relative decreases in maternal control from early to late adolescence. More emotional variability of mother–adolescent dyads serves an important function in adaptively dealing with relational challenges that arise during adolescence.
Le neurofeedback comme outil de compréhension et de régulation de l’attention
Authors: Micoulaud Franchi J.-A. 
Published: November 2013

Le « neurofeedback » est une technique de biofeedback, appelée également « EEG biofeedback », utilisant l’enregistrement électroencéphalographique (EEG). Cette technique existe depuis près de 30 ans. Deux grands types de protocoles de neurofeedback en fonction du type de traitement en temps réel réalisé sur le signal EEG sont retrouvés. Dans le premier, la puissance spectrale d’une bande fréquentielle EEG en regard d’une région cérébrale est calculée. Il peut être par exemple demandé au sujet d’augmenter la puissance spectrale de la bande bêta ou de diminuer celle de la bande thêta enregistrées sur l’électrode Cz, donc en regard de la région centrale médiale. Dans le second, l’amplitude d’un potentiel lent, appelé SCP pour Slow Cortical Potential, en Cz est calculé. Il est alors demandé au sujet soit d’augmenter, soit de diminuer l’amplitude du SCP. Le neurofeedback permet principalement de favoriser les capacités attentionnelles et d’éveil d’un sujet. Ainsi son application thérapeutique est principalement le trouble déficit de l’attention avec hyperactivité (TDAH), où il s’agit d’une technique désormais considérée comme valide. Il est également utilisé comme thérapeutique complémentaire non pharmacologique dans la prise en charge des troubles envahissant du développement et dans les épilepsies pharmacorésistantes. Ces applications dans d’autres troubles psychiatriques restent plus marginales. Le neurofeedback est très peu connu et développé en France. Pourtant, il permet un renouveau de la neurophysiologie clinique en psychiatrie en proposant une approche thérapeutique et ouvre des voies de recherches neurophysiologiques novatrices.
L’adaptation cognitive, un processus sensorimoteur ? Homologies cingulaires entre le singe et l’homme
Authors: Procyk E. 
Published: November 2013

Le dysfonctionnement des mécanismes d’adaptation cognitive se retrouve dans diverses pathologies et sous différentes formes : altérations de l’organisation temporelle du comportement, hyper- ou hypo-réactivité aux feedbacks de l’action, persévérations, etc. Le cortex frontal des primates est une des pièces maîtresses de l’adaptation cognitive et, de fait, une cible privilégiée pour les études fondamentales et cliniques. Cet exposé se concentre sur une subdivision du cortex frontal des primates humain et non humain, le cortex cingulaire médian. Le rôle précis de cette région est extrêmement débattu, et son organisation fonctionnelle méconnue même si elle est la cible d’approches thérapeutiques modernes, notamment pour le traitement de dépressions ou de TOC résistants, qui peuvent être considérés sous l’angle de dysfonctionnements adaptatifs. Nous proposons ici d’éclairer le débat en combinant recherches fondamentales chez le singe et neuro-imagerie individuelle chez l’Homme. Nous montrerons, sur la base d’études histologiques, électrophysiologiques et d’IRM fonctionnelle chez l’Homme et le singe, que les cartes somatomotrices identifiables dans le cortex cingulaire médian traitent les informations pertinentes pour l’adaptation. Nos expériences ont deux caractéristiques importantes. Elles utilisent tout d’abord des protocoles comportementaux similaires chez l’humain et le singe. Par ailleurs, elles tirent partie des variations morphologiques cérébrales inter-individuelles chez l’Homme, afin d’affiner au mieux les cartographies fonctionnelles obtenues par l’imagerie fonctionnelle. Nos expériences chez le singe, puis leur réplication chez l’Homme, montrent que le cortex cingulaire médian traite en priorité les feedbacks de l’action qui sont pertinents pour l’adaptation, mais pas ceux obtenus lorsque l’adaptation n’est pas nécessaire [2,3]. De façon remarquable, le traitement des feedbacks de l’action implique les représentations somatomotrices cingulaires correspondantes à la nature de ces feedbacks (gustatifs, tactiles) [1]. Ces approches comparatives chez le singe et l’Homme suggèrent donc que le cortex cingulaire médian fonctionne comme un système de surveillance incarné des informations nécessaires ou pertinentes pour l’adaptation cognitive.
Mélancolie suite à une accusation de vol : à propos de trois observations cliniques

Published: November 2013

La mélancolie ou « folie calme » de Pinel a perdu depuis les années 80, son caractère de maladie autonome. Actuellement dans le DSM, elle désigne seulement une caractéristique des états dépressifs. Pourtant ce terme renvoie à un concept psychopathologique particulier dont la connaissance permet une meilleure compréhension de la maladie et une meilleure approche des patients. Nous mettrons ce concept à l’épreuve de la clinique chez trois patients ayant été hospitalisés pour un épisode mélancolique suite à une accusation de vol. Deux de nos patients ont présenté un syndrome délirant à thématique de persécution. Chez l’un d’eux, l’évolution s’est malheureusement faite vers le suicide. Nous essaierons à travers les vignettes cliniques de faire le point sur le rôle du narcissisme dans la psychopathologie de la mélancolie. En effet, chez nos trois patients, l’accusation de vol représente un événement traumatisant venant ébranler la relation à l’objet. Le moi appauvri en libido et fragile, s’identifie à l’objet frustrant afin de le préserver et le protéger de sa haine et de son activité destructrice. Il procède ainsi à une régression narcissique au stade oral tardif. Mais le moi ayant incorporé l’objet se trouve en conflit avec une autre instance qui est le surmoi. Ce dernier par sa fonction culpabilisante permet au mélancolique de se défendre contre l’incapacité du moi à être conforme à son idéal. Dans notre contexte culturel, le surmoi se trouve être plus collectif qu’individuel. Devant la perte de l’objet, l’introjection laisse la place à la projection de la haine sur un objet extérieur faisant émerger le délire de persécution. Enfin, quand l’identification à l’objet devient totale, les mouvements agressifs envers l’objet sont alors dirigés vers le moi aboutissant au non réparable qu’est le suicide.
