Interventionist Curatorial and Display Practices in Beijing
Authors: Sanderson Edward 
Published: March 2015

Abstract
Over the past decade, a number of curatorial and exhibitionary practices have developed in China that intervene into daily life. Interventionist practice partly develops from dissatisfaction with the marked division between the commercial art world and the everyday realities of cultural producers. They also develop from a desire to create a common space of engagement for artists and the local public. While much of this work is not overtly political, the prevailing social conditions of an authoritarian state lend these practices a critical edge, which can lead to surveillance, censorship and other consequences. This article surveys curatorial and artistic interventions in Beijing, placing them in the specific context of the various neighbourhoods, such as the 798 Art District, the city centre, Caochangdi village, and the industrialized suburbs.

Modernizing Traditions on the Roof of the World: Displaying ‘Liberation’ and ‘Occupation’ in Three Tibet Museums
Authors: Keränen Lisa , Dodge Patrick Shaou-Whea , Conley Donovan 
Published: March 2015

Abstract
This article investigates the representational interplay between tradition and modernity in three museums about Tibet: the Tibet Museum in Lhasa, China; the Qinghai Tibetan Culture Museum in Xining, China; and the Tibet Museum in Dharamsala, India. Analyzing how each museum displays Tibetan heritage, three modalities of representing Tibetan culture and Tibet’s disputed ‘liberation’ are identified – triumphant modernization, spectacular sacralization, and catastrophic witnessing. Each modality reproduces, counters and complicates dominant Chinese narratives concerning Tibet’s history, culture and political status. Also discussed are the implications of these practices for displaying contested cultural narratives in contemporary China.
AlGaInAs MOVPE selective area growth for photonic integrated circuits
Authors: Decobert Jean , Binet Guillaume , Maia Alvaro D. B. , Lagrée Pierre-Yves , Kazmierski Christophe 
Published: March 2015

Abstract
We developed a generic photonic integration platform based on selective area growth (SAG) by metal organic vapor-phase epitaxy (MOVPE) of AlGaInAs/InP multiple quantum well (MQW) material. For efficient and predictive band gap engineering of photonic integrated circuits, different SAG zones of active and passive function heterostructures are precisely modeled and characterized. With the vapor-phase diffusion model, using numerical simulations of finite volumes, we extracted the three effective diffusion lengths of Al, Ga, and In species. In our growth conditions, these lengths were 32, 65, and 14 μm, respectively. The Kardar-Parisi-Zhang (KPZ) equation, a classic approach to describe the growing interface profile, is used. AlGaInAs MQW properties are then simulated in terms of thickness, composition, band gap, and biaxial strain variations. Highly resolved μ-photoluminescence and optical interferometer microscopy measurements confirm the validity of the band gap and thickness variations for both bulk and MQW layers. A new diffractometer, with a submillimeter X-ray spot, was used to study the structural properties of the MQW in the center of the SAG area. As an application, we present the realization and operation of full-monolithic high-speed advanced modulation format transmitters based on novel prefixed optical phase switching by fast electro-absorption modulators.
Bacteria homologus to Aeromonas capable of microcystin degradation

Published: March 2015

Abstract
Water blooms dominated by cyanobacteria
are capable of producing hepatotoxins known as
microcystins. These toxins are dangerous to people and
to the environment. Therefore, for a better understanding
of the biological termination of this increasingly
common phenomenon, bacteria with the potential to
degrade cyanobacteria-derived hepatotoxins and the
degradative activity of culturable bacteria were studied.
Based on the presence of the mlrA gene, bacteria with a
homology to the Sphingopyxis and Stenotrophomonas
genera were identified as those presenting potential for
microcystins degradation directly in the water samples
from the Sulejów Reservoir (SU, Central Poland). However,
this biodegrading potential has not been confirmed in in
vitro experiments. The degrading activity of the culturable
isolates from the water studied was determined in more
than 30 bacterial mixes. An analysis of the biodegradation
of the microcystin-LR (MC-LR) together with an analysis of
the phylogenetic affiliation of bacteria demonstrated for
the first time that bacteria homologous to the Aeromonas
genus were able to degrade the mentioned hepatotoxin,
although the mlrA gene was not amplified. The maximal
removal efficiency of MC-LR was 48%. This study
demonstrates a new aspect of interactions between the
microcystin-containing cyanobacteria and bacteria from
the Aeromonas genus.
Putting the Jigsaw Together - A Brief Insight Into the Tularemia
Authors: Kubelkova K. , Macela A. 
Published: March 2015

Abstract
Tularemia is a debilitating febrile and potentially
fatal zoonotic disease of humans and other vertebrates
caused by the Gram-negative bacterium Francisella
tularensis. The natural reservoirs are small rodents,
hares, and possibly amoebas in water. The etiological
agent, Francisella tularensis, is a non-spore forming,
encapsulated, facultative intracellular bacterium, a
member of the γ-Proteobacteria class of Gram-negative
bacteria. Francisella tularensis is capable of invading and
replicating within phagocytic as well as non-phagocytic
cells and modulate inflammatory response. Infection
by the pulmonary, dermal, or oral routes, respectively,
results in pneumonic, ulceroglandular, or oropharyngeal
tularemia. The highest mortality rates are associated
with the pneumonic form of this disease. All members of
Francisella tularensis species cause more or less severe
disease Due to their abilities to be transmitted to humans
via multiple routes and to be disseminated via biological
aerosol that can cause the disease after inhalation of even
an extremely low infectious dose, Francisella tularensis
has been classified as a Category A bioterrorism agent. The
current standard of care for tularemia is treatment with
antibiotics, as this therapy is highly effective if used soon
after infection, although it is not, however, absolutely
effective in all cases.

Abstract
In this study, an efficient and reproducible plant
regeneration system for lotus (Nelumbo nucifera Gaertn.)
was established using shoot apical meristems from the
buds and one-week-old aseptically germinated embryos
as explants. Multiple shoot clumps were induced on
Murashige and Skoog (MS) basal medium supplemented
with various combinations of N6-Benzylaminopurine
(6-BA) and α-Naphthalene acetic acid (NAA). The
maximum response was obtained with 2.22 μM 6-BA, and
produced 21.33 shoots per explant after four weeks. After
five subcultures, multiple shoot clumps were transferred
to MS basal medium supplemented with various
combinations of 3-Indolebutyric acid (IBA), NAA and
sucrose for root induction. After four weeks, plantlets with
well-developed roots were achieved on MS basal medium
supplemented with 0.54 μM NAA and 30 g/L sucrose with
100% rooting rate. The successfully acclimated plantlets
were transferred to pots with the addition of 2 g/L KMnO4
into the soils, and finally fertile plants with much bigger
leaves were obtained in the greenhouse. The survival rate
was 97.33%.
Is the translational approach becoming a reality in nanomedicine?
Authors: Malhaire Hélène , Lagarce Frederic 
Published: March 2015

AbstractThis paper summarizes the key points discussed at the international conference held in Angers (France) on translational nanomedicine. During 3 days, more than 150 attendees presented their works and discussed through plenary sessions on how to translate to the clinics the discoveries found at lab scale. The importance of interdisciplinary works has been emphasized. New promising strategies inspired by biology were presented, such as bacteriophage associated silicon particles (BASP) in cancer therapy. Green nanotechnology, which limits the use of potentially toxic excipients to the benefit of natural compounds, is growing. Although there are various financial helps for the research and the training of next generations of researchers, the difficulties to find funding to go to the clinics has been illustrated by the squalene-conjugated nanoparticles that find no industrial support. Large-scale production of nanomedicines is also challenging to implement and pharmaceutical companies are developing new large-scale production tools to reach the patient bedside. Last but not least, regulation requirements and patenting have been forced to evolve and adapt to these particular vectors. As a conclusion, transversal collaborative research and a design of nanomedicine based on simplicity are two important levers to help these promising drugs to reach the patient.

Published: March 2015

Abstract
The microstructural changes in a selection of softwoods and hardwoods resulting from thermo-hydro treatment (THT) at 160°C were examined by means of a state-of-the-art micro X-ray computed tomography. A dedicated X-ray scanning and volumetric processing protocol was developed. All reconstructed volumes had an approximate voxel pitch between 0.8 and 1.2 μm3. The microstructures of the same needle-shaped specimens before and after THT were visualized, and the individual parameters (maximum opening and lumen volume) for various cell types were quantified and compared. The highest values of substance volume were recorded for the ash sapwood (81%) and spruce specimens (72%). After THT, a significant correlation was found between the mass loss determined by gravimetry and the X-ray volume loss. The largest change occurred in the lumen volume of several tissue components, such as libriform fibers, tracheids, and ray parenchyma. The average aspen fiber volume reduction after THT was 31%, a value 2.6 times higher than the volume reduction of the average vessels. The porosity of ash sapwood increased from 41 to 56%, whereas the porosity of birch decreased from 34 to 29%.

AbstractThe histological assessment of spinal cord tissue in three dimensions has previously been very time consuming and prone to errors of interpretation. Advances in tissue clearing have significantly improved visualization of fluorescently labelled axons. While recent proof-of-concept studies have been performed with transgenic mice in which axons were prelabeled with GFP, investigating axonal regeneration requires stringent axonal tracing methods as well as the use of animal models in which transgenic axonal labeling is not available. Using rodent models of spinal cord injury, we labeled axon tracts of interest using both adeno-associated virus and chemical tracers and performed tetrahydrofuran-based tissue clearing to image multiple axon types in spinal cords using light sheet and confocal microscopy. Using this approach, we investigated the relationships between axons and scar-forming cells at the injury site as well as connections between sensory axons and motor pools in the spinal cord. In addition, we used these methods to trace axons in nonhuman primates. This reproducible and adaptable virus-based approach can be combined with transgenic mice or with chemical-based tract-tracing methods, providing scientists with flexibility in obtaining axonal trajectory information from transparent tissue.
Systematic analysis of BRAFV600E melanomas reveals a role for JNK/c‐Jun pathway in adaptive resistance to drug‐induced apoptosis

Published: March 2015

AbstractDrugs that inhibit RAF/MEK signaling, such as vemurafenib, elicit profound but often temporary anti‐tumor responses in patients with BRAFV600E melanoma. Adaptive responses to RAF/MEK inhibition occur on a timescale of hours to days, involve homeostatic responses that reactivate MAP kinase signaling and compensatory mitogenic pathways, and attenuate the anti‐tumor effects of RAF/MEK inhibitors. We profile adaptive responses across a panel of melanoma cell lines using multiplex biochemical measurement, single‐cell assays, and statistical modeling and show that adaptation involves at least six signaling cascades that act to reduce drug potency (IC50) and maximal effect (i.e., Emax ≪ 1). Among these cascades, we identify a role for JNK/c‐Jun signaling in vemurafenib adaptation and show that RAF and JNK inhibitors synergize in cell killing. This arises because JNK inhibition prevents a subset of cells in a cycling population from becoming quiescent upon vemurafenib treatment, thereby reducing drug Emax. Our findings demonstrate the breadth and diversity of adaptive responses to RAF/MEK inhibition and a means to identify which steps in a signaling cascade are most predictive of phenotypic response.

O estudo comparou o efeito de grupo genético e dieta com duas fontes de ureia sobre características de desempenho, carcaça e carne de cordeiros. O experimento foi realizado na FAZU, Uberaba, MG. Utilizaram-se 12 cordeiros mestiços Dorper e 12 mestiços Texel, oriundos de cruzamento de matrizes Santa Inês com reprodutores puros de origem de cada raça. Os cordeiros foram divididos em dois grupos e mantidos em piquetes de capim Ãries (Panicum maximum cv. Ãries), recebendo concentrado contendo ureia pecuária ou ureia encapsulada, à vontade. O delineamento experimental foi inteiramente casualizado em esquema fatorial onde se avaliou as duas fontes de nitrogênio não proteico e dois grupos genéticos (mestiços Dorper ou Texel). As médias foram avaliadas pelo teste de Tukey a 5% de probabilidade. Os tratamentos não influenciaram o ganho de peso diário (0,256 kg/dia). O uso da ureia encapsulada proporcionou maior rendimento de carcaça quente e fria quando comparada a dieta com ureia pecuária. As perdas por resfriamento foram menores para os mestiços Texel (3,87%) em comparação aos mestiços Dorper (6,88%). A espessura de gordura (1,81 mm), conformação (2,98), valores de L (36,77), teor de a* (6,04), teor de b* (6,73) e força de cisalhamento (5,68 kgf) não foram alterados pelos tratamentos empregados. A ureia encapsulada proporcionou maior rendimento de carcaça e menor perda no resfriamento.

Background: The present study aims to investigate the effects of systemic melatonin administration on alveolar bone resorption in experimental periodontitis in rats.Methods: Twenty‐four male Sprague‐Dawley rats were divided into three groups (control, experimental periodontitis [Ped], and experimental periodontitis treated with melatonin [Mel‐Ped]). For periodontitis induction, first molars were ligatured submarginally for 4 weeks. After ligature removal, rats in the Mel‐Ped group were treated with a daily single dose of 10 mg/kg body weight melatonin for 15 consecutive days. At the end of the study, intracardiac blood samples and mandible tissues were obtained for histologic, biochemical, and radiographic analysis. Serum markers related to bone turnover, calcium, phosphorus, bone alkaline phosphatase (b‐ALP), and terminal C telopeptide of collagen Type I (CTX) were analyzed. Myeloperoxidase levels were determined in gingival tissue homogenates, and receptor activator of nuclear factor‐kappa B ligand (RANKL) activation was analyzed in the mandible samples stereologically. Alveolar bone loss was also evaluated radiographically in the mandible samples of each group.Results: Melatonin treatment decreased serum CTX levels and increased b‐ALP levels. Serum calcium and phosphorus levels were not statistically different among groups (P >0.05). Alveolar bone resorption and myeloperoxidase activity were statistically higher in the Ped group compared to the Mel‐Ped group (P <0.05). Immunohistochemical staining of RANKL and osteoclast activity were significantly lower in the Mel‐Ped group compared to the Ped group (P <0.05).Conclusion: This study reveals that melatonin treatment significantly inhibits regional alveolar bone resorption and contributes to periodontal healing in an experimental periodontitis rat model.
Performance Aggregation and Decentralized Contracting
Authors: Feltham Gerald A. , Hofmann Christian , Indjejikian Raffi J. 
Published: March 2015

ABSTRACT
We examine how accounting practices that aggregate or disaggregate the contributions of different economic agents influence the choice of organizational form. We consider a principal/multi-agent model where the principal either contracts with all parties directly or delegates part of the contracting authority to one of the agents. Delegated contracts improve risk sharing and generate implicit incentives for the agent entrusted with contracting authority. However, delegated contracts also entail a loss of control in motivating lower-level agents. In addition, when performance is aggregated, delegated contracts render agents' incentives more interdependent and create spillovers up and down the hierarchy. We demonstrate that accounting practices that aggregate the performance of multiple agents can complement organizational forms characterized by greater decentralization. In contrast, accounting practices that capture agents' performance contributions separately favor more centralized organizational forms. Our findings suggest that in settings where performance measurement systems are more aggregate, decentralization is more prevalent.
