description: Myxomas are the most common cardiac tumors; however right ventricular myxomas are very rare. We present the case of an asymptomatic 74 year old female with a right ventricular myxoma originating from the interventricular septum diagnosed during a routine echocardiographic examination. Initially the patient refused surgery due to being asymptomatic, but agreed to be operated two months later. Surgical removal was uneventful, as was the postoperative course. Histopathological analysis confirmed the suspected diagnosis of cardiac myxoma.

description: We quantize the massless p-form field that obeys the generalized Maxwell field equations in curved spacetimes of dimension n > 1. We begin by showing that the classical Cauchy problem of the generalized Maxwell field is well posed and that the field possess the expected gauge invariance. Then the classical phase space is developed in terms of gauge equivalent classes, first in terms of the Cauchy data and then reformulated in terms of Maxwell solutions. The latter is employed to quantize the field in the framework of Dimock. Finally, the resulting algebra of observables is shown to satisfy the wave equation with the usual canonical commutation relations.

description: Introduction: Inflammation is a common underlying feature of atherosclerosis. Several inflammatory biomarkers have been reported to have prognostic value, in several areas, including in vascular surgery. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) may permit to identify patients at greater risk for cerebrovascular events, tailor patient management, improve preoperative status and possibly develop target anti-atherosclerotic therapy. However, studies reporting usefulness of these hematological biomarkers in the context of carotid artery disease are still scarce. The aim of this study was to review the literature concerning the prognostic ability of NLR and PLR in the subpopulation of vascular patients with carotid artery disease. Methods: A Medline search was performed in order to identify publications focused on the physiopathology of NLR and PLR and their impact in the management of patients with carotid artery disease. Results: The study identified 18 articles with a total of 5339 patients. NLR is associated with carotid intima-media thickness, carotid plaques, carotid stenosis, symptomatic stenosis and intra-stent restenosis after carotid artery stenting and cognitive dysfunction after carotid endarterectomy. PLR is associated with carotid stenosis, symptomatic stenosis and predicts post-operative outcomes after carotid artery revascularization, including post-operative stroke, acute coronary syndrome and all-cause mortality. Conclusions: The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have the ability to predict sub-clinic atherosclerosis, atherosclerosis progression in carotid artery disease and propensity for carotid stenosis to become symptomatic along with morbidity following CEA and carotid stenting. Consequently, these parameters may be considered to tailored therapy and improve patient management.

description: CONTEXT: The RAVE spectroscopic survey for galactic structure and evolution obtains 8400-8800 Ang spectra at 7500 resolving power at the UK Schmidt Telescope using the 6dF multi-fiber positioner. More than 300,000 925 deg southern stars have been observed to date. AIMS: This paper presents the first intrinsic examination of stellar spectra from the RAVE survey, aimed at evaluating their diagnostic potential for peculiar stars and at contributing to the general understanding of Luminous Blue Variables (LBVs). METHODS: We used the multi-epoch spectra for all seven LBVs observed, between 2005 and 2008, in the Large Magellanic Cloud (LMC) by the RAVE survey. RESULTS: We demonstrate that RAVE spectra possess significant diagnostic potential when applied to peculiar stars and, in particular, LBVs. The behaviour of the radial velocities for both emission and absorption lines, and the spectral changes between outburst and quiescence states are described and found to agree with evidence gathered at more conventional wavelengths. The wind outflow signatures and their variability are investigated, with multi-components detected in S Doradus. Photoionisation modelling of the rich emission line spectrum of R 127 shows evidence of a massive detached ionised shell that was ejected during the 1982-2000 outburst. Surface inhomogeneities in the nuclear-processed material, brought to the surface by heavy mass loss, could have been observed in S Doradus, even if alternative explanations are possible. We also detect the transition from quiescence to outburst state in R 71. Finally, our spectrum of R 84 offers one of the clearest views of its cool companion.

Lateral effects in a thermal boundary layer

Publisher: name: University of British Columbia
Year: 2011

description: Analytical and numerical analyses along with experimental results are presented for laminar forced convection from a heated flat plate. The heating is of either the constant flux or constant temperature type with a discontinuity in the lateral as well as the free-stream direction. The principal objective was to examine the disturbance created by the lateral discontinuity in heating. Analytical solutions of the boundary layer type relating the wall temperature variation to a specific heat flux distribution were found. These involve Heaviside calculus, Fourier transform techniques and the Lévque velocity approximation, and although formally correct only as the Prandtl number approaches infinity, are found to be fairly accurate for Prandtl numbers as low as unity. Reduction of the energy equation to a two-dimensional elliptic equation by a double similarity transform enabled the calculation of numerical solutions valid in any free-stream cross-section removed from the leading edge. Results for technologically interesting cases of heated strips were found by superposition. The error in assuming such strips to be two-dimensional throughout their lateral extent is calculated. A velocity profile corresponding with the Blasius profile and a cross-sectional temperature field above a wind tunnel model of a heated flat plate were measured with a constant temperature anemometer and a rake of miniature thermocouples respectively. A temperature profile well into the heated portion is of two-dimensional form and the temperature field at the lateral step correlates with a numerical solution. In general, there is good agreement between all three approaches.

description: Introduction: Ruptured abdominal aortic aneurysm’s treatment relies on the emergent surgery, considering preoperative prognosis. There are several scores that estimate perioperative mortality of ruptured abdominal aortic aneurysm, however, the accuracy of such algorithms in some populations remains unknown. Objective: Compare the prognostic validity of the Weingarten score with the Glasgow Aneurysm Score and the Vancouver Scoring System. Validation of three prognostic ruptured abdominal aortic aneurysms tools for the Portuguese population. Material and Methods: A retrospective analysis of consecutive patients with ruptured abdominal aortic aneurysm surgically treated, in a peripheral and in a referral hospital between 2012 and 2016 was performed. The 30-day mortality discriminative power was analysed using each score. Results: 120 patients were included. The mean Glasgow Aneurysm Score was 98.53 ± 19.57, the Vancouver Scoring System was 3.64 ± 1.43. The Weingarten score classified 51 (43.2%) patients as stable and 67 (56.8%) as unstable. The three scores demonstrated some predictive value concerning mortality, although Glasgow Aneurysm Score demonstrated the highest area under the ROC curve (0.74) and the best discriminatory capacity for cut-off points with higher specificity. Neither of the scores demonstrated clinically useful predictive value. Conclusions: The Weingarten score did not present as a superior prediction model of preoperative mortality in ruptured abdominal aortic aneurysm. None of the scores, even when optimized for a higher specificity, could select which patients will not benefit from surgical intervention. The Glasgow Aneurysm Score was validated for the Portuguese population.

description: We study charged dilaton black branes in $AdS_4$. Our system involves a dilaton $ϕ$ coupled to a Maxwell field $F_{μν}$ with dilaton-dependent gauge coupling, ${1\over g^2} = f^2(ϕ)$. First, we find the solutions for extremal and near extremal branes through a combination of analytical and numerical techniques. The near horizon geometries in the simplest cases, where $f(ϕ) = e^{αϕ}$, are Lifshitz-like, with a dynamical exponent $z$ determined by $α$. The black hole thermodynamics varies in an interesting way with $α$, but in all cases the entropy is vanishing and the specific heat is positive for the near extremal solutions. We then compute conductivity in these backgrounds. We find that somewhat surprisingly, the AC conductivity vanishes like $ω^2$ at T=0 independent of $α$. We also explore the charged black brane physics of several other classes of gauge-coupling functions $f(ϕ)$. In addition to possible applications in AdS/CMT, the extremal black branes are of interest from the point of view of the attractor mechanism. The near horizon geometries for these branes are universal, independent of the asymptotic values of the moduli, and describe generic classes of endpoints for attractor flows which are different from $AdS_2\times R^2$.

description: Background: Placement of chest drain following thoracoscopic procedures has been the gold standard. Nevertheless, a drainless approach may be safe and feasible in selected patients and procedures. In this study we aim to report our clinical experience after drainless video-assisted thoracoscopic surgery. Methods: We retrospectively analyzed data of all subjects submitted to drainless video-assisted thoracoscopic surgery at our centre between January 1, 2010 and December 31, 2019. The preoperative clinical and surgical data and the immediate postoperative data were retrospectively evaluated through the consultation of the clinical processes and the computer registry system. We used descriptive statistics: mean or median, according to data distribution, and absolute or relative frequencies. Results: We included 161 patients, mean age of 31 years (min:15; max:78). We analyzed data from patients submitted to: thoracic sympathectomy(67.1%), wedge resection, for lung biopsy, metastasis or small nodules resection (21.7%), mediastinal cysts removal (6.2%), pleural lesions resection (3.7%) and emphysematous bullae resection (1.2%). The average length of stay was 1 day. Residual pneumothorax was noted in 15 patients (9.3%). Postoperative pleural drain placement due to pneumothorax occur in 4 patients (2.5%). There was no intra-hospitalar mortality. Conclusions: Video-assisted thoracoscopic surgery without postoperative chest drain seems to be valid and safe according to our results.

description: A calix[4]arene ligand, in which two of the phenol functions are replaced by pyrazole units has been employed to mimic the His2–Tyr2 (His: histidine, Tyr: tyrosine) ligand sphere within the active site of the galactose oxidase (GO). The calixarene backbone forces the corresponding copper(II) complex into a see‐saw‐type structure, which is hitherto unprecedented in GO modelling chemistry. It undergoes a one‐electron oxidation that is centered at the phenolate donor leading to a copper‐coordinated phenoxyl radical like in the GO. Accordingly, the complex was tested as a functional model and indeed proved capable of oxidizing benzyl alcohol to the respective aldehyde using two phenoxyl‐radical equivalents as oxidants. Finally, the results show that the calixarene platform can be utilized to arrange donor functions to biomimetic binding pockets that allow for the creation of novel types of model compounds.

Shuart Women's Research Collection at the University of Houston Libraries: Nevertheless, She Persisted! Women as Historic Influencers and Leagues of Their Own: Representing 60 Years of Women's Athletics Achievement. Central to securing funding was a proposal focused on creating opportunities for University of Houston graduate students to curate exhibits in alignment with the Libraries' strategic goals to support student success through developing meaningful co-curricular learning opportunities. By aligning the proposal and associated programs with opportunities for student involvement, the Special Collections department engaged in a new approach to exhibits while providing meaningful educational experiences for our students. The funding supported graduate student curators, mentored by Special Collections staff, as well as costs related to exhibit installation, reformatting of materials, creation of facsimiles for display, and public programming. These initiatives allowed students to engage fully in every aspect of the exhibition process from early research and material selection to writing exhibit texts and collaborating on exhibit installation and design. This session will highlight how donor collaboration, a focus on student learning, a willingness to give up the reigns, and targeted fundraising enabled us to expand our exhibits program, enriching both the student experience and the library's public offerings.

description: Introduction/Study Goals: Thoracic sympathectomy is considered to be the most effective treatment for hyperhidrosis, a procedure traditionally performed under general anesthesia. Nowadays it’s a minimally invasive procedure, which makes it possible to perform under sedation with local anesthesia. The goal in this study was to assess the efficacy and safety of this anesthetic technique in video-assisted thoracic sympathectomy. Material and Methods: The study took place in Centro Hospitalar Universitário Lisboa Norte, between June 2017 and September 2019. The anesthetic technique consisted in a propofol infusion titrated to achieve a moderate to deep sedation, in addition to local anesthesia with lidocaine 2% and ropivacaine 0,75% on surgical incisions. All patients were assessed subsequently for pain and anesthetic or surgical complications, with a 30-day follow-up. Results: From a final sample of 63 patients, most were female (70%), with age ranging between 15 and 57 years old. There were no intra-operative complications. On the immediate postoperative period there were only two cases of poorly controlled pain. Conclusion: Results showed efficiency and safety with sedation associated with local anaesthesia as an anaesthetic technique for video-assisted thoracic sympathectomy. This anaesthetic approach avoids possible complications associated with general anaesthesia and one lung ventilation, with good analgesic efficacy. However, there is still the need for a bigger sample to confirm the obtained results and to strengthen sedation as an anesthetic approach in thoracic sympathectomy.

description: In this paper, we study the relationship between polynomial integrals on the unitary group and the conjugacy class expansion of symmetric functions in Jucys-Murphy elements. Our main result is an explicit formula for the top coefficients in the class expansion of monomial symmetric functions in Jucys-Murphy elements, from which we recover the first order asymptotics of polynomial integrals over $\U(N)$ as $N \rightarrow \infty$. Our results on class expansion include an analogue of Macdonald's result for the top connection coefficients of the class algebra, a generalization of Stanley and Olshanski's result on the polynomiality of content statistics on Plancherel-random partitions, and an exact formula for the multiplicity of the class of full cycles in the expansion of a complete symmetric function in Jucys-Murphy elements. The latter leads to a new combinatorial interpretation of the Carlitz-Riordan central factorial numbers.

The role of northern Canadian Indian women in social change
Creators: name: Cruikshank, Julia M.
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines the changing role of Indian women, particularly in northern Canadian communities where the pace of directed change has been compressed during the past twenty-five years. In the area now designated 'Yukon Territory' live descendents of Athapaskan, Inland Tlingit and Tagish speaking peoples. It is suggested here that the woman's role is potentially very important in determining the direction of change within Indian communities. Despite radical alterations in the Indian way of life, discontinuity is less abrupt for the women because the role of mother links them both with the past and with the future. In a situation of change, links are necessary to bridge the gap between the past and the future if cultural identity is to be maintained. Cross-cultural data suggests that women's potential in this role is being recognized in many areas of the world. In Canada, this is frequently ignored. Indian men and women are often lumped as an undifferentiated group without recognition of individual needs and capabilities. Since the building of the Alaska highway and the opening up of mines, an industrial economy has displaced the former hunting and trapping economy in the Yukon. Many Indian men are abandoning traditional economic pursuits and are expected to compete with non-Indians in activities for which they are often not technically or psychologically prepared. In the new cultural environment Indian women are presented with opportunities for independent activity which were traditionally not available to them. With new opportunities come new and often conflicting expectations, held both by Indians and by non-Indians, about ways in which an Indian woman should behave. A variety of government agencies claim a vested interest in, and a responsibility for, an Indian family. Each agency places independent demands on the mother, often with very little comprehension of her aims, goals and values. Indian women have access to sources of information which are less available to Indian men. They use this information to reformulate their own ideas about their place in the changing environment. Practical possibilities for greater involvement of women in change do exist; however, this involvement trust occur on the women's own terms rather than solely on the terms of individuals who deal with women in an administrative capacity.

description: Using images from the Spitzer GLIMPSE Legacy survey, we have identified more than 300 extended 4.5 micron sources (abbreviated EGO, Extended Green Object, for the common coding of the [4.5] band as green in 3-color composite IRAC images). We present a catalog of these EGOs, including integrated flux density measurements at 3.6, 4.5, 5.8, 8.0, and 24 microns from the GLIMPSE and MIPSGAL surveys. The average angular separation between a source in our sample and the nearest IRAS point source is >1 arcminute. The majority of EGOs are associated with infrared dark clouds (IRDCs), and where high-resolution 6.7 GHz methanol maser surveys overlap the GLIMPSE coverage, EGOs and 6.7 GHz methanol masers are strongly correlated. Extended 4.5 micron emission is thought to trace shocked molecular gas in protostellar outflows; the association of EGOs with IRDCs and 6.7 GHz methanol masers suggests that extended 4.5 micron emission may pinpoint outflows specifically from massive protostars. The mid-infrared colors of EGOs lie in regions of color-color space occupied by young protostars still embedded in infalling envelopes.

description: Objectives: We aim to report our experience on venoarterial extracorporeal membrane oxygenation (VA-ECMO) for postcardiotomy shock (PCS). Methods: Single center, retrospective study of all patients on VA-ECMO for PCS, from November 2006 to July 2019. Pediatric and adult patients were analysed separately. Primary outcomes were survival to discharge and one-year survival. Results: Twenty-nine patients were included. Pediatric group (group PED) (62%, n=18): mean age 1,3±2,1 years and 39% male. Adults (group AD) (38%, n=11): mean age 55,6±15,9 years and 64% male. Indications in group PED were complex congenital heart surgery (94%) and heart transplant (6%), with 27% being reoperations; in group AD valvular surgery (45%), aortic surgery (21%), coronary artery bypass grafting (18%) and pulmonary endarterectomy (9%); 45% were reoperations. ECMO support was initiated intraoperatively due to failure to wean from cardiopulmonary bypass in 28% of group PED and 73% of group AD. Central cannulation was performed in all pediatric patients and 82% adults. Bleeding was the most common complication in both groups (group PED 39%, group AD 45%). Mean ECMO support time was respectively 6,2±4,9 and 6,2± 3,6 days for group PED and group AD. Weaning rate was 44% in group PED (with 2 patients bridged to LVAD) and 45% in group AD. Survival to discharge as well as one-year survival were both 28% in group PED and 18% in group AD. Conclusion: Despite low survival and high complication rates, VA ECMO support provides a survival benefit in refractory cases, with a dismal prognosis, that would otherwise die.

description: Objectives: Our objective was to examine the results of ECMO post cardiotomy in Centro Hospitalar Universitário S. João (CHUSJ). Methods: Between 2011 and 2019, 13 patients were cannulated for refractory cardiogenic shock post-cardiotomy; 8 (61,5%) male and 5 (38,5%) female. Patients under 18 years old were excluded. Data was collected from hospital archives concerning preoperative comorbidities, open-heart surgery procedure, dates of ECMO cannulation and decannulation, postoperative complications, hospital mortality and cause of death. Follow-up was obtained by review of the last outpatient observation. The outcomes investigated were hospital mortality and survival at 12, 36 and 60 months. Results: After a median ECMO-VA therapy of 6 days (1-16 days), 7 (53,8%) patients were successfully decannulated; from these 2 succumbed from stroke and septic shock, one is still in intermediate care convalescing steadily and 4 were discharged. Overall 8 (61,5%) patients died. 5 (38,5%) survived, 4 were discharged home and 1 is still in intermediate care. Survival (after discharge) at 12, 36 and 60 months was respectively 25%, 16,7% and 8,3%. Regarding postoperative complications, reoperation for bleeding was necessary in 5 (38.5%), stroke was diagnosed in 2 (15,4%), dialysis in 6 (46,2%), leg ischemia affected 5 (38,5%) and mediastinitis occurred in 1 (7,7%). Conclusions: VA ECMO saves a life in each three patients suffering from refractory cardiogenic shock after cardiac surgery. Despite risks associated with advanced cardiopulmonary support, survivors maintain good health condition.

description: Approximately one-third of women and one-fifth of men aged 60 and over in the U.S. live alone and are at heightened risk of social isolation due to social distancing and other safety precautions introduced to curtail the spread of COVID-19. This brief, from PRC faculty research associate Karen Fingerman and colleagues, reports on a recent study which examines how daily positive emotions and negative emotions vary based on whether people live alone during the pandemic. They found that older adults who live alone experienced more positive emotions when they saw someone in person compared to those who had no in-person contact but that older adults who live alone experienced more negative emotions, especially loneliness, when they talked to someone on the phone. They are argue that those who want to support emotional well-being in older adults who live alone with in-person contact should do so while following COVID-19 safety guidelines.

description: Let X be a smooth proper variety over a perfect field k of arbitrary characteristic. Let D be an effective divisor on X with multiplicity. We introduce an Albanese variety Alb(X, D) of X of modulus D as a higher dimensional analogon of the generalized Jacobian of Rosenlicht-Serre with modulus for smooth proper curves. Basing on duality of 1-motives with unipotent part (which are introduced here), we obtain explicit and functorial descriptions of these generalized Albanese varieties and their dual functors. We define a relative Chow group of zero cycles w.r.t. the modulus D and show that Alb(X, D) is a universal quotient of this Chow group. As an application we can rephrase Lang's class field theory of function fields of varieties over finite fields in explicit terms.

Realization of minimal two-element-kind one-port networks
Creators: name: Mason, Lloyd Judson
Publisher: name: University of British Columbia
Year: 2011

description: A new method of realizing two-element-kind driving-point Impedances is given and illustrated by examples. In this method, networks of any desired topology and having a minimum of elements are utilized. A transformation to normal coordinates forms the basis of the method and, in order to determine network element values, evaluation of the associated transformation matrix is necessary. This matrix is found by formulating and solving a set of multivariable polynomial equations of second degree. The solution to this set of polynomial equations is obtained by a numerical perturbation procedure. To initiate the procedure, a set of element values is chosen, and the network of specified topology is analysed. The corresponding transformation matrix and driving-point impedance are determined from this analysis. The impedance parameters are then perturbed by small amounts in the direction of the specified ones, and the resulting changes in the transformation matrix are calculated. The process is continued until the transformation matrix corresponding to the specified impedance is obtained. A detailed description of the computer program written to carry out the above procedure is Included. A large number of examples of various complexities, including some canonic structures, have been realized by the method. Examples show the superiority of the numerical method to conventional procedures for solving multivariable nonlinear equations. In particular, the choice of the initial set of element values is not required to be close to the final set to achieve convergence to a solution. Some restrictions on the realizability of irreducible complementary tree structures are reported. It is shown that the specification parameters may have local extrema at a point where the Jacobian of the system of polynomial equations vanishes. Examples which support these results are given.

description: Abstract: Disaster plans in libraries, archives, and museums center collections recovery but overlook the simultaneous impact that disasters have on our staff. These plans assume an immediate response to disaster and collections recovery which can be unrealistic or impossible to activate when disaster disrupts the lives of those responsible for leading and executing recovery efforts. Most disaster plans and recovery response literature focus on the necessity for rapid recovery of materials which may produce better outcomes for overall collection recovery and loss minimization, and doesn't account for the personal and community impacts of extreme weather. Library staff dealing with extreme weather events and recovery at home while shouldering the burden of recovering their collections are faced with the impossible challenge of balancing the two, compounding trauma and stress for staff.
This presentation explores the necessity to shift responsibility for disaster recovery, adjust and adapt response approaches, and improve priority setting so that staff needs are incorporated into institutional documentation and recovery plans. Using recent extreme weather events in the Houston metro-area as examples, this presentation will highlight how these events affected library staff, making existing recovery plans impractical and unworkable. By highlighting gaps in current institutional disaster response policies, the speaker will propose a framework for institutional recovery after extreme weather events – one that prioritizes the well-being of staff and formalizes this care in institutional documentation and disaster recovery plans.

description: We investigate effects of cluster particle correlations on two- and three-particle azimuth correlator observables sensitive to local strong parity violation. We use two-particle angular correlation measurements as input and estimate the magnitudes of the effects with straightforward assumptions. We found that the measurements of the azimuth correlator observables by the STAR experiment can be entirely accounted for by cluster particle correlations together with a reasonable range of cluster anisotropy in non-peripheral collisions. Our result suggests that new physics, such as local strong parity violation, may not be required to explain the correlator data.

description: When an infectious disease strikes a population, the number of newly reported cases is often the only available information that one can obtain during early stages of the outbreak. An important goal of early outbreak analysis is to obtain a reliable estimate for the basic reproduction number, $R_{0}$, from the limited information available. We present a novel method that enables us to make a reliable real-time estimate of the reproduction number at a much earlier stage compared to other available methods. Our method takes into account the possibility that a disease has a wide distribution of infectious period and that the degree distribution of the contact network is heterogeneous. We validate our analytical framework with numerical simulations.

Quantum Darwinism in non-ideal environments

description: Quantum Darwinism provides an information-theoretic framework for the emergence of the objective, classical world from the quantum substrate. The key to this emergence is the proliferation of redundant information throughout the environment where observers can then intercept it. We study this process for a purely decohering interaction when the environment, E, is in a non-ideal (e.g., mixed) initial state. In the case of good decoherence, that is, after the pointer states have been unambiguously selected, the mutual information between the system, S, and an environment fragment, F, is given solely by F's entropy increase. This demonstrates that the environment's capacity for recording the state of S is directly related to its ability to increase its entropy. Environments that remain nearly invariant under the interaction with S, either because they have a large initial entropy or a misaligned initial state, therefore have a diminished ability to acquire information. To elucidate the concept of good decoherence, we show that - when decoherence is not complete - the deviation of the mutual information from F's entropy change is quantified by the quantum discord, i.e., the excess mutual information between S and F is information regarding the initial coherence between pointer states of S. In addition to illustrating these results with a single qubit system interacting with a multi-qubit environment, we find scaling relations for the redundancy of information acquired by the environment that display a universal behavior independent of the initial state of S. Our results demonstrate that Quantum Darwinism is robust with respect to non-ideal initial states of the environment: the environment almost always acquires redundant information about the system but its rate of acquisition can be reduced.

Alkaline phosphatase and embryogenesis in two urodele amphibian species
Creators: name: O'Day, Danton H.
Publisher: name: University of British Columbia
Year: 2011

description: The development of alkaline phosphatase (AP) has been studied in two species of Urodele amphibian, Ambystoma qracile and Taricha torosa. The enzyme is present in embryo homogenates at gastrulation and increases immensely in activity as development proceeds to the free-swimming stages. The activity level is a product of two isozymic forms that change quantitatively. Using histochemical detection methods, it was possible to correlate the specific activity and electrophoretic data with histological AP development. Some function of AP were related to the available data. A correlation between substrate specificities and function is proposed which may assist in understanding the role of AP in the process of differentiation
