AbstractThe divergent evolution of niche‐related traits can facilitate adaptive radiation, yet identification of the genetic or molecular mechanisms underlying such trait changes remains a major challenge in evolutionary biology. Conducting a detailed morphological comparison along growth trajectories is a powerful method for observing the formation of differences in niche‐related traits. Here, we focused on hindlimb length of Anolis lizards, differences in which are related to adaptation for use of different microhabitats. We measured the length of hindlimb skeletons in different ecomorphs of anole lizards (A. sagrei, a trunk‐ground ecomorph with long hindlimbs, and A. angusticeps, a twig ecomorph with short hindlimbs) from early embryonic stages to adulthood, to determine which hindlimb elements mainly differentiate the species and the timing of the formation of these differences. With respect to the digit, differences between the species mainly occurred during the embryonic stages of interdigit reduction, when the cartilage of the distal phalanges was simultaneously forming. In addition, we compared the relative length of developing autopods in early embryonic stages using whole‐mount in situ hybridization before the formation of the cartilaginous bones, and the results showed that the relative growth rate of the Hoxa11‐negative distal region in A. sagrei was greater than that in A. angusticeps. Our results show that there are several important developmental stages for hindlimb length differentiation between A. angusticeps and A. sagrei, depending on which hindlimb element is considered. In particular, the species differences were largely due to variations in digit length, which arose at early embryonic stages. J. Exp. Zool. (Mol. Dev.

Published: June 2015

AbstractThe paper proposes a new theoretical model based on local thermodynamic equilibrium enabling the prediction of gas generation during the reaction of aluminum‐based thermites. We demonstrate that the model has the capability to predict the total pressure and the partial pressures of its components as a function of the reaction extent and compaction. Al/CuO, Al/Bi2O3, Al/Sb2O3, Al/MoO3, and Al/WO3 thermites are modeled and their capability to generate pressure is compared. Simulation results are also validated through dedicated experiments and show general agreement beyond the state of the art. Mechanisms underlying pressure generation are detailed. A two‐stage process for the pressure increase in Al/CuO reaction, also observed experimentally, is shown to be driven by oxygen generation as produced by CuO and Cu2O vaporization through different kinetics. Comparison with experimental data stresses the issue of understanding the complex chemical processes taking place during vaporization and subsequent gas phase reactions and the need to determine their thermodynamic constants.

AbstractBackgroundThe purpose of this study was to evaluate the feasibility and safety of a single‐port assisted three‐incision robotic hysterectomy or myomectomy with manual morcellation using a scalpel, and to introduce our novel surgical technique.MethodsBetween October 2010 and July 2014, 16 patients underwent robotic hysterectomy and 50 patients underwent robotic myomectomy using a single‐port assisted three‐incision technique. Manual morcellation through a single‐port site without power morcellation was used to remove the uterus or uterine fibroids.ResultsThe mean operative times were 130.2 ± 32.6 min in the hysterectomy group and 178.8 ± 77.9 min in the myomectomy group. Intraoperative complications, including a rectal serosa injury and a small bowel injury, occurred in two cases. Three febrile morbidities occurred postoperatively. Finally, no complications were associated with manual morcellation.ConclusionsUterine tissues could be removed without any complications by manual morcellation within an endobag, using a scalpel.

Causes of mortality and temporal patterns in breeding season survival of lesser prairie‐chickens in shinnery oak prairies
Authors: Grisham Blake A. , Boal Clint W. 
Published: June 2015

ABSTRACTBaseline survival and mortality data for lesser prairie‐chickens (Tympanuchus pallidicinctus) are lacking for shinnery oak (Quercus havardii) prairies. An understanding of the causes and timing of mortalities and breeding season survival in this ecoregion is important because shinnery oak prairies have hotter and drier environmental conditions, as well as different predator communities compared with the northern distribution of the species. The need for this information has become more pressing given the recent listing of the species as threatened under the U.S. Endangered Species Act. We investigated causes of mortality and survival of lesser prairie‐chickens during the 6‐month breeding season (1 Mar–31 Aug) of 2008–2011 on the Texas Southern High Plains, USA. We recorded 42 deaths of radiotagged individuals, and our results indicated female mortalities were proportionate among avian and mammalian predation and other causes of mortality but survival was constant throughout the 6‐month breeding season. Male mortalities were constant across avian and mammalian predation and other causes, but more mortalities occurred in June compared with other months. Male survival also varied by month, and survival probabilities were lower in June–August. We found predation on leks was rare, mortalities from fence collisions were rare, female survival did not decrease during incubation or brood‐rearing, and survival was influenced by drought. Our study corroborated recent studies that suggested lesser prairie‐chickens are living at the edge of their physiological tolerances to environmental conditions in shinnery oak prairies. As such, lesser prairie‐chickens in our study experienced different patterns of mortality and survival that we attributed to hot, dry conditions during the breeding season. Specifically, and converse to other studies on lesser prairie‐chicken survival and mortality, drought positively influenced female survival because females did not incubate eggs during drought conditions; the incubation period is when females are most vulnerable to predation. Male mortalities and survival were negatively influenced by drought later in the breeding season, which we attributed to rigorous lekking activities through late May combined with lack of food and cover as the breeding season progressed into summer. © 2015 The Wildlife Society.

AbstractBackgroundSwitzerland is a region in which alveolar echinococcosis (AE) is endemic. Studies evaluating outcomes after liver resection (LR) for AE are scarce. The aim of this study was to assess the short‐ and long‐term outcomes of AE patients after LR in a single tertiary referral center.MethodsWe retrospectively analyzed data pertaining to all patients with liver AE who were treated with LR at our institution between January 1992 and December 2013. Patient demographics, intraoperative data, extent of LR procedures (major vs. minor LR), postoperative outcomes, and negative histological margin (R0) resection rate were recorded in a database. Recurrence rates after LR were analyzed.ResultsLR was performed in 59 patients diagnosed with hepatic AE (56 complete surgeries, 3 reduction surgeries). Postoperative morbidity and mortality were observed in 34 % (25 % grade I–II, 9 % grade III–IV) and 2 % of the patients, respectively. R0 (complete) resection rate was 71 % (n = 42), and R1/R2 resection rate was 29 % (n = 17). Extra‐hepatic recurrence occurred in 1 case (lung) after R0 resection. In cases of R1/R2 resection, 7 intra‐hepatic disease progressions occurred with a median time of 10 months (IQR 6–11 months). Long‐term (more than 1 year) benzimidazole treatment stabilized the disease in 64 % (9/14) of patients with R1 status. The overall survival rate was 97 %.ConclusionsLiver AE can be safely and definitively treated with LR, provided that R0 resection is achieved. In cases of R1 resection, benzimidazole therapy seems to be effective in stabilizing the intra‐hepatic disease and preventing extra‐hepatic recurrence.

AbstractBackgroundObesity is associated with poor surgical outcomes and disparity in access‐to‐care. There is a lack of quality data on the effect of body mass index (BMI) on perioperative outcomes. Accordingly, we sought to determine the procedure specific, independent‐effect of BMI on 30‐day perioperative outcomes in patients undergoing major surgery.MethodsParticipants included individuals undergoing one of 16 major surgery (cardiovascular, orthopedic, oncologic; n = 141,802) recorded in the ACS‐NSQIP (2005–2011). Outcomes evaluated included complications, blood transfusion, length‐of‐stay (LOS), re‐intervention, readmission, and perioperative mortality. Multivariable‐regression models assessed the independent‐effect of BMI on outcomes.ResultsNearly, 74 % of patients had a BMI disturbance; the majority being overweight (35.3 %) or obese (29.8 %). Morbidly obese patients constituted a small but significant proportion of the patients (5.7 %; n = 8067). In adjusted‐analyses, morbidly obese patients had significantly increased odds of wound complications in 15 of the examined procedures, of renal complications after 6‐procedures, of thromboembolism after 5‐procedures, of pulmonary, septic and UTI complications after 2‐procedures, and of cardiovascular complications after CABG. Conversely, obese/overweight patients, except for increased odds of wound complications after select procedures, had significantly decreased odds of perioperative mortality, prolonged‐LOS and blood transfusion relative to normal BMI patients after 4, 8, and 9 of the examined procedures.ConclusionsThe prevalence of BMI derangements in surgical patients is high. The effect of BMI on outcomes is procedure specific. Patients with BMI between 18.5 and 40‐kg/m2 at time of surgery fare equally well with regard to complications and mortality. However, morbidly obese patients are at‐risk for postsurgical complications and targeted preoperative‐optimization may improve outcomes and attenuate disparity in access‐to‐care.
Moving Studies: Somatic-Performative Research in a Wide Dance Field
Authors: Fernandes Ciane 
Published: June 2015

This is a presentation of the principles of somatic-performative research with application to the audience's research. The proposal has been developed over ten years of artistic-scientific research at the Graduate Program of Performing Arts of Federal University of Bahia, Salvador BA, Brazil. The approach associates Somatic Education and Performance in dance research, especially regarding inner impulse in relation to the environment and collective awareness in a micro-macro political attitude.While quantitative and qualitative research deals with practice as an object of study, in performative research, practice is in itself a research method (Haseman 2006). Somatic-performative research is defined and organized by thesomatic practice (“experienced body”), transforming the ephemeral nature of dance into the research'smodus operandi. From the starting point of inter-artistic moving principles with/in the environment, the object of study becomes a creative, live, and relational subject. Therefore, studies and methods become contaminated by the subject's dynamic nature, melting any prejudice ora priorisettings. In an unpredictable, autonomous, yet integrated, pulsing that destabilizes borders, discourses, and manners, dance becomes a spread-out medium of studies (rather than something to be studied).As an integrated “soma,” dance research constantly dis-re-organizes “the way we form things,” subverting power relationships and discourses over art and the body. Somatic-performative exploration dilutes the separation and conflict between practice and theory, body and mind, art and science, dynamic multidimensional movement and fixed linear record, human and environment, place and non-place, matter and energy. In a connecting quantumspacetime, “being” is permanently perceived and reinvented as trans-cellular intelligence in movement or creative somatic wisdom in a “culture of becoming” with/in a “deep ecology.”

Published: June 2015

AbstractSearch for Majorana fermions renewed interest in semiconductor–superconductor interfaces, while a quest for higher-order non-Abelian excitations demands formation of superconducting contacts to materials with fractionalized excitations, such as a two-dimensional electron gas in a fractional quantum Hall regime. Here we report induced superconductivity in high-mobility two-dimensional electron gas in gallium arsenide heterostructures and development of highly transparent semiconductor–superconductor ohmic contacts. Supercurrent with characteristic temperature dependence of a ballistic junction has been observed across 0.6 μm, a regime previously achieved only in point contacts but essential to the formation of well separated non-Abelian states. High critical fields (>16 T) in NbN contacts enables investigation of an interplay between superconductivity and strongly correlated states in a two-dimensional electron gas at high magnetic fields.

AbstractLarge datasets are emerging in many fields of image processing including: electron microscopy, light microscopy, medical X-ray imaging, astronomy, etc. Novel computer-controlled instrumentation facilitates the collection of very large datasets containing thousands of individual digital images. In single-particle cryogenic electron microscopy (“cryo-EM”), for example, large datasets are required for achieving quasi-atomic resolution structures of biological complexes. Based on the collected data alone, large datasets allow us to precisely determine the statistical properties of the imaging sensor on a pixel-by-pixel basis, independent of any “a priori” normalization routinely applied to the raw image data during collection (“flat field correction”). Our straightforward “a posteriori” correction yields clean linear images as can be verified by Fourier Ring Correlation (FRC), illustrating the statistical independence of the corrected images over all spatial frequencies. The image sensor characteristics can also be measured continuously and used for correcting upcoming images.

AbstractNovelty seeking (NS) is a personality trait reflecting excitement in response to novel stimuli. High NS is usually a predictor of risky behaviour such as drug abuse. However, the relationships between NS and risk-related cognitive processes, including individual risk preference and the brain activation associated with risk prediction, remain elusive. In this fMRI study, participants completed the Tridimensional Personality Questionnaire to measure NS and performed a probabilistic decision making task. Using a mathematical model, we estimated individual risk preference. Brain regions associated with risk prediction were determined via fMRI. The NS score showed a positive correlation with risk preference and a negative correlation with the activation elicited by risk prediction in the right posterior insula (r-PI), left anterior insula (l-AI), right striatum (r-striatum) and supplementary motor area (SMA). Within these brain regions, only the activation associated with risk prediction in the r-PI showed a correlation with NS after controlling for the effect of risk preference. Resting-state functional connectivity between the r-PI and r-striatum/l-AI was negatively correlated with NS. Our results suggest that high NS may be associated with less aversion to risk and that the r-PI plays an important role in relating risk prediction to NS.

AbstractTailoring the spin orientation at the atomic scale has been a key task in spintronics technology. While controlling the out-of-plane to in-plane spin orientation has been achieved by a precise control of the perpendicular magnetic anisotropy at atomic layer thickness level, a design and control of the in-plane magnetic anisotropy has not yet been well developed. On well aligned atomic steps of a 6° vicinal Cu(001) surface with steps parallel to the [110] axis, we grow Py/Ni overlayer films epitaxially to permit a systematic exploration of the step-induced in-plane magnetic anisotropy as a function of both the Py and the Ni film thicknesses. We found that the atomic steps from the vicinal Cu(001) induce an in-plane uniaxial magnetic anisotropy that favors both Py and Ni magnetizations perpendicular to the steps, opposite to the behavior of Co on vicinal Cu(001). In addition, thickness-dependent study shows that the Ni films exhibit different magnetic anisotropy below and above ~6 ML Ni thickness.

AbstractThe ubiquitin-protein ligase E3C (UBE3C) belongs to the E3 ligase enzyme family and implicates in the ubiquitin-proteasome pathway, thus regulates physiological and cancer-related processes. Here, we investigated the expression and roles of UBE3C in glioma. We demonstrated that UBE3C was overexpressed in glioma tissues and cell lines. Inhibition of UBE3C expression in glioma cells significantly decreased cell migration and invasion in vitro. Mechanistically, we disclosed that UBE3C physically interacted with and ubiquitinated tumor suppressor gene annexin A7 (ANXA7), resulting in ubiquitination and degradation of ANXA7. Our results also revealed that increased UBE3C expression was accompanied by a reduction in ANXA7 protein expression in glioma tissues, but not ANXA7 mRNA. Importantly, the inhibition of ANXA7 expression in gliomas cells with UBE3C interference could rescue the cell invasion. Clinically, UBE3C overexpression significantly correlated with high-grade tumors (p < 0.05), poor overall survival and early tumor recurrence. Thus, our data reveal that high UBE3C expression contributes to glioma progression by ubiquitination and degradation of ANXA7 and thus presents a novel and promising target for glioma therapy.

Published: June 2015

AbstractRecently, we succeeded in detwinning REBa2Cu3O7 (RE123, RE = rare-earth elements)-coated conductors by annealing under an external uniaxial strain. Using the untwinned RE123 tapes, the uniaxial-strain dependencies of the critical temperature Tc along the a and b crystal axes were investigated over a wide strain region from compression to tension. We found that the strain dependencies of Tc for the a and b axes obey a power law but exhibit opposite slopes. In particular, the maximum value of Tc is obtained when the CuO2 plane becomes a square and its lattice constant is close to 0.385 nm. It is suggested that a tetragonal structure with a ≈ 0.385 nm is the optimum condition for a high critical temperature in high-Tc cuprates.
Transient silencing of the KASII genes is feasible in Nicotiana benthamiana for metabolic engineering of wax ester composition

Published: June 2015

AbstractThe beta-ketoacyl-ACP synthase II (KASII) is an enzyme in fatty acid biosynthesis, catalyzing the elongation of 16:0-acyl carrier protein (ACP) to 18:0-ACP in plastids. Mutations in KASII genes in higher plants can lead to lethality, which makes it difficult to utilize the gene for lipid metabolic engineering. We demonstrated previously that transient expression of plastid-directed fatty acyl reductases and wax ester synthases could result in different compositions of wax esters. We hypothesized that changing the ratio between C16 (palmitoyl-compounds) and C18 (stearoyl-compounds) in the plastidic acyl-ACP pool by inhibition of KASII expression would change the yield and composition of wax esters via substrate preference of the introduced enzymes. Here, we report that transient inhibition of KASII expression by three different RNAi constructs in leaves of N. benthamiana results in almost complete inhibition of KASII expression. The transient RNAi approach led to a shift of carbon flux from a pool of C18 fatty acids to C16, which significantly increased wax ester production in AtFAR6-containing combinations. The results demonstrate that transient inhibition of KASII in vegetative tissues of higher plants enables metabolic studies towards industrial production of lipids such as wax esters with specific quality and composition.
