Ascidian photosymbiosis: Diversity of cyanobacterial transmission during embryogenesis
Authors: Hirose Euichi 
Published: April 2014

SummarySome tropical ascidians of the family Didemnidae invariably harbor cyanobacterial cells in the common cloacal cavities and/or tunic. This is the only lifelong, obligate photosymbiosis reported in chordates. Photosymbionts are transferred from the maternal colony to embryos or prehatching larvae brooded in the colonies. Here we review the diversity of modes of cyanobacterial transmission to shed a light on the evolutionary history of ascidian photosymbiosis. Ascidian species exhibit several modes of cyanobacterial transmission. In Diplosoma species, the mode is constrained phylogenetically; all photosymbiotic Diplosoma have the same mode of transmission using a unique organ known as the rastrum. In other photosymbiotic species, the mode is constrained by the distribution pattern of photosymbionts in the host colony. Species of different genera have similar modes of transmission wherein they harbor cyanobacterial cells at similar sites within colonies. Accordingly, host species of distinct lineages likely acquired similar modes of transmission convergently. Why obligate photosymbiosis was established exclusively in these didemnid ascidians remains uncertain. Ascidian photosymbiosis is discussed from the viewpoint of evolution and diversification of vertical transmission. genesis 53:121–131, 2015. © 2014 Wiley Periodicals, Inc.
Neural crest cell‐specific inactivation of Nipbl or Mau2 during mouse development results in a late onset of craniofacial defects
Authors: Smith Terence Gordon , Laval Steve , Chen Fangli , Rock Matthew James , Strachan Tom , Peters Heiko 
Published: April 2014

SummaryNipbl (Scc2) and Mau2 (Scc4) encode evolutionary conserved proteins that play a vital role for loading the cohesin complex onto chromosomes, thereby ensuring accurate chromosome segregation during cell division. While mutations in human NIPBL are known to cause the developmental disorder Cornelia de Lange syndrome, the functions of Nipbl and Mau2 in mammalian development are poorly defined. Here we generated conditional alleles for both genes in mice and show that neural crest cell‐specific inactivation of Nipbl or Mau2 strongly affects craniofacial development. Surprisingly, the early phase of neural crest cell proliferation and migration is only moderately affected in these mutants. Moreover, we found that Mau2 single homozygous mutants exhibited a more severe craniofacial phenotype when compared to that of Nipbl;Mau2 double homozygous mutants. This raises the possibility that the Mau2/Nipbl protein interaction is not only required for cohesin loading, but may also be required to restrict the level of Nipbl involved in regulating gene expression. Together, the data suggest that proliferating neural crest cells tolerate a substantial reduction of cohesin loading proteins and we propose that the successive decrease of cohesin loading proteins in neural crest cells may alter developmental gene regulation in a highly dynamic manner. genesis 52:687–694, 2014. © 2014 Wiley Periodicals, Inc.
Salinity, groundwater, and water uptake depth of plants in coastal uplands of Everglades National Park (Florida, USA)
Authors: Saha Sonali , Sadle Jimi , van der Heiden Craig , Sternberg Leonel 
Published: April 2014

AbstractWe examine salinity, ground water depth, and water uptake of common plant species in coastal upland communities: buttonwood hammocks, hardwood hammocks, and buttonwood prairies of Everglades National Park. We show that the elevation gradient is gentle with a mean gradient of 0.12 m North American Vertical Datum of 1988 from buttonwood prairie to hardwood hammocks, but the species composition and canopy cover among communities are different. Plant communities differ significantly in groundwater salinity. Hardwood hammocks have brackish groundwater [14–27 parts per thousand (PPT)], buttonwood hammocks have brackish to saline groundwater (23–35 PPT), and buttonwood prairies have saline groundwater (30–44 PPT). The depth to water table is greater for plants in hardwood and buttonwood hammocks than in buttonwood prairies, which makes the freshwater recharge capacity of vadose zone larger in hammocks than in buttonwood prairies. The majority of species accessed water from deep soil (5–30 cm) and groundwater in dry season and switched to using shallow soil water (0–5 cm) in wet season. Exception to this pattern is herbaceous Chromolaena frustrata, endemic to buttonwood hammocks of South Florida, which accessed shallow soil water in dry season and deep soil water in wet season. Our study assesses susceptibility of coastal upland species to sea level rise (SLR)‐driven changes in water table and salinity; the results of which can be incorporated into planning for adaptation to SLR.

Rescaling of Resource Governance as Institutional Change: Explaining the Transformation of Water Governance in Southern Spain
Authors: Thiel Andreas 
Published: April 2014

ABSTRACTThis paper develops a conceptual framework highlighting the functional and constitutional (two‐level) negotiation aspects of water governance rescaling, illustrated by the case of southern Spanish water governance reorganization for the Guadalquivir River Basin. The framework is derived from theories of institutional change and multi‐level governance. A necessary precondition for rescaling is changes in actor‐specific perceptions concerning how to best address priorities of water management through water governance. Predominant in rescaling is its coincidence with a contingent political majority of these actors enabling agreement on changes in governance conforming to existing constitutional rules for negotiation. Ultimately, in southern Spain, the constitutional setting prevented re‐scaling. It had initially been promoted by regional actors benefitting from a contingent political majority at the federal as well as at the state level. The paper highlights that, in the context of transformations of European water governance, in Spain supranational policy‐making is of low significance domestically.

Innovative substructuring technique for hybrid simulation of multistory buildings through collapse
Authors: Hashemi M. Javad , Mosqueda Gilberto 
Published: April 2014

SUMMARYHybrid simulation combines numerical and experimental methods for cost‐effective, large‐scale testing of structures under simulated dynamic earthquake loads. Particularly for experimental seismic collapse simulation of structures, hybrid testing can be an attractive alternative to earthquake simulators due to the limited capacity of most facilities and the difficulties and risks associated with a collapsing structure on a shaking table. The benefits of hybrid simulation through collapse can be further enhanced through accurate and practical substructuring techniques that do not require testing the entire structure. An innovative substructuring technique for hybrid simulation of structures subjected to large deformations is proposed to simplify the boundary conditions by overlapping the domains between the numerical and experimental subassemblies. The advantages of this substructuring technique are the following: it requires only critical components of the structure to be tested experimentally; it reduces the number of actuators at the interface of the experimental subassemblies; and it can be implemented using typically available equipment in laboratories. Compared with previous overlapping methods that have been applied in hybrid simulation, this approach requires additional sensing in the hybrid simulation feedback loop to obtain internal member forces, but provides significantly better accuracy in the highly nonlinear range. The proposed substructuring technique is verified numerically and validated experimentally, using the response of a four‐story moment‐resisting frame that was previously tested to collapse on an earthquake simulator.

Emotion recognition processing as early predictor of response to 8‐week citalopram treatment in late‐life depression
Authors: Shiroma Paulo R. , Thuras Paul , Johns Brian , Lim Kelvin O. 
Published: April 2014

BackgroundIn subjects with depression, exposure to antidepressants improves recognition of positive emotions. This phenomenon, which occurs early in the course of treatment, has been proposed as the initial step in the mechanism of action to subsequent therapeutic effects of antidepressants. To this date, it has not been well examined among older depressed patients.MethodOlder subjects with non‐psychotic major depressive disorder were treated with citalopram in an 8‐week open‐label study. The main predictor of response and remission was the change in emotion recognition between baseline and day 7. Covariates included executive functions, baseline anxiety level, medical comorbidity, level of subjective stress, serum citalopram level, and level of social support.ResultsTwenty‐seven patients were considered for final analysis. Overall, accuracy of emotion recognition significantly improved between baseline (75%) and day 7 (83%) (X2 = 34.50, df = 1, p < 0.001). Improvement to identify happy expressions occurred at 25% and 50% intensity with ceiling effect at 0%, 75%, and 100%. Change in emotion processing was marginally significant in predicting antidepressant response at day 56. Multivariate analysis showed that emotion processing is a significant predictor of response and remission when considered along with perceived level of social support.ConclusionsRecognition of mildly intense happy expression, which improved early in the course of citalopram treatment, predicts subsequent antidepressant response and remission when considered along with perception of social support. Further studies would be necessary to examine specific neural substrates in the affective network involved in the acute therapeutic action of antidepressant in late‐life depression.

Hundred forty eight more days with depression: the association between marital conflict and depression‐free days
Authors: Park Mijung , Unützer Jürgen 
Published: April 2014

BackgroundAlthough collaborative care programs are effective in improving late‐life depression, only about half of treated patients achieve clinically meaningful improvement. Thus, we need to examine what characteristics may predict poor late‐life depression course. Despite the robust evidence for the negative association between the quality of couple relationships and depression outcomes, few studies have examined these associations in the context of long‐term late‐life depression course.AimThe objective of this study is to examine the relations between the severity of couple conflict, receiving collaborative depression care program, and 24‐months depression outcomes.MethodsStudy sample comprised 840 depressed older adults subsample from the improving mood, promoting access to collaborative treatment for late‐life depression trial (IMPACT). Depression and couple conflict were assessed at baseline, 12‐month, and 24‐month follow‐up. Descriptive statistics and multivariate regression analyses were performed to examine mean 24‐month depression‐free days (DFD) and the marginal effects of receiving IMAPCT program over usual care among participants with varying degrees of 24‐month couple conflict.ResultsCompared with those who never endorsed frequent couple conflict over the three observation points, those who did twice had 63 fewer DFD (p = 0.01), and those who did three times experienced 148 fewer DFD (p < 0.001). Although the marginal effects of receiving IMPACT program over usual care was greater in overall sample, it was not statistically significant among those who endorsed frequent conflict at two or three times.ConclusionFrequent couple conflict is associated with worse long‐term late‐life depression outcomes among the patients in primary care clinics.

Published: April 2014

AbstractPresurgical monitoring with intracerebral electrodes in patients with drug‐resistant focal epilepsy represents a standard invasive procedure to localize the sites of seizures origin, defined as the epileptogenic zone (EZ). During presurgical evaluation, intracerebral single‐pulse electrical stimulation (SPES) is performed to define the boundaries of eloquent areas and to evoke seizure‐associated symptoms. Extensive intracranial exploration and stimulation generate a large dataset on brain connectivity that can be used to improve EZ detection and to understand the organization of the human epileptic brain. We developed a protocol to analyse field responses evoked by intracranial stimulation. Intracerebral recordings were performed with 105–162 recording sites positioned in fronto‐temporal regions in 12 patients with pharmacoresistant focal epilepsy. Recording sites were used for bipolar SPES at 1 Hz. Reproducible early and late phases (<60 ms and 60–500 ms from stimulus artefact, respectively) were identified on averaged evoked responses. Phase 1 and 2 responses recorded at all and each recording sites were plotted on a 3D brain reconstructions. Based on connectivity properties, electrode contacts were primarily identified as receivers, mainly activators or bidirectional. We used connectivity patterns to construct networks and applied cluster partitioning to study the proprieties between potentials evoked/stimulated in different regions. We demonstrate that bidirectional connectivity during phase 1 is a prevalent feature that characterize contacts included in the EZ. This study shows that the application of an analytical protocol on intracerebral stimulus‐evoked recordings provides useful information that may contribute to EZ detection and to the management of surgical‐remediable epilepsies.

Nonlinear Interdependence Between the US and Emerging Markets' Industrial Stock Sectors
Authors: Choudhry Taufiq , Osoble Bashir Nur 
Published: April 2014

AbstractThis paper investigates the time‐varying, long‐run and short‐run dynamic relationships between stock industrial sectors of the US and three leading emerging markets/countries: Brazil, Malaysia, and South Africa between January 2000 and December 2009. A crucial empirical contribution of the study is the application of the nonlinear econometric time series techniques for the evaluation of the long‐run global relationships and causality linkages. Further contribution is the application of industrial sector indices rather than national indices. The results of the time‐varying analysis reaffirm the view that relationships between global financial markets tend to be quite volatile over time and particularly high in a time of high financial turbulence. Overall, the relatively weak interdependence between the US and the emerging markets' industry sectors suggests potential diversification benefits for investors in diversifying their portfolio investment across industrial sectors of emerging markets.

Authors: Liu Vincent , Lei Xingye , Prescott Hallie C. , Kipnis Patricia , Iwashyna Theodore J. , Escobar Gabriel J. 
Published: April 2014

BACKGROUNDSepsis, the most expensive cause of hospitalization in the United States, is associated with high morbidity and mortality. However, healthcare utilization patterns following sepsis are poorly understood.OBJECTIVETo identify patient‐level factors that contribute to postsepsis mortality and healthcare utilization.DESIGN, SETTING, PATIENTSA retrospective study of sepsis patients drawn from 21 community‐based hospitals in Kaiser Permanente Northern California in 2010.MEASUREMENTSWe determined 1‐year survival and use of outpatient and facility‐based healthcare before and after sepsis and used logistic regression to identify the factors that contributed to early readmission (within 30 days) and high utilization (≥15% of living days spent in facility‐based care).RESULTSAmong 6344 sepsis patients, 5479 (86.4%) survived to hospital discharge. Mean age was 72 years with 28.9% of patients aged <65 years. Postsepsis survival was strongly modified by age; 1‐year survival was 94.1% for <45 year olds and 54.4% for ≥85 year olds. A total of 978 (17.9%) patients were readmitted within 30 days; only a minority of all rehospitalizations were for infection. After sepsis, adjusted healthcare utilization increased nearly 3‐fold compared with presepsis levels and was strongly modified by age. Patient factors including acute severity of illness, hospital length of stay, and the need for intensive care were associated with early readmission and high healthcare utilization; however, the dominant factors explaining variability—comorbid disease burden and high presepsis utilization—were present prior to sepsis admission.CONCLUSIONPostsepsis survival and healthcare utilization were most strongly influenced by patient factors already present prior to sepsis hospitalization.

Authors: Jiang Li , Chen Huijun , Li Rui , Han Xu , Chen Zhensen , He Le , Yuan Chun , Zhao Xihai 
Published: April 2014

PurposeTo investigate the correlations of arterial distensibility between carotid arteries and abdominal aorta by MR.Materials and MethodsTwenty eight asymptomatic old subjects (71.4 ± 6.7 years; 14 males) and 20 healthy young subjects (23.5 ± 1.0 years; 10 males) were imaged with electrocardiograph‐triggered balanced turbo field echo sequence sequence. Arterial distensibility was calculated as the relative lumen area change against unit blood pressure change and its relationship between carotid arteries and abdominal aorta was determined.ResultsThe arterial distensibility in old subjects was significantly smaller than that in young subjects for left carotid artery (19.0 ± 6.6 × 10−3/kpa versus 30.9 ± 6.5 × 10−3/kpa), right carotid artery (16.7 ± 6.1 × 10−3/kpa versus 28.6 ± 9.3 × 10−3/kpa), and abdominal aorta (14.3 ± 5.5 × 10−3/kpa versus 37.5 ± 8.8 × 10−3/kpa), respectively (all P < 0.001). In both age groups, distensibility of the abdominal aorta was strongly correlated with that of the left carotid artery (old age group: r = 0.553; P = 0.004; young age group: r = 0.487; P = 0.029) but not with that of the right carotid artery (old age group: r = 0.371; P = 0.062; young age group: r = 0.189; P = 0.424).ConclusionThe distensibility of abdominal aorta is much more strongly associated with that of the left carotid artery compared with that of the right carotid artery.
