The intersection of ecological risk assessment and plant communities: an analysis of Agrostis and Panicum species in the northeastern U.S.

Ecological risk assessments for grass species with novel traits are advisable, or required, in order to identify potential environmental harms prior to large-scale cultivation. Credible risk assessments are built upon knowledge of the communities that could be negatively affected by crop-to-wild gene flow, new weeds, or invasive plants. This study focused on two cultivated grasses with different life histories: the exotic, weedy Agrostis stolonifera (creeping bentgrass) and the native Panicum virgatum (switchgrass). Vascular plant communities were analyzed in 190 transects (50 m) in ten habitat types across two ecoregions (inland and coastal) in the northeastern U.S. Ordination plots and dendrogram analysis showed clustering of inland plant community assemblages within habitat types, while coastal plant communities were similar across the habitats studied. Agrostis and Panicum species had unequal distribution across the habitat types and ecoregions. Agrostis species were more common in the inland ecoregion and habitats receiving moderate management or disturbance events. In both ecoregions, A. stolonifera had high co-occurrence values with other exotic Agrostis species, suggesting potential for interspecific gene flow. P. virgatum was most common in inland roadside and wasteland habitats, but was distributed equally in the three coastal habitats. Co-occurrence between P. virgatum and congenerics was infrequent, although one transect had both P. virgatum and the state-listed coastal species Panicum amarum. This is the first study to characterize Agrostis and Panicum plant communities and distribution providing the basis for ecological risk assessments, coexistence-strategies, and geographic exclusion zones.
A Qualitative Discussion of Mechanisms of Feedback and Feedforward in the Control of Locomotion

A brief discussion of the kinematics and dynamics of biped locomotion is provided. A number of elementary control problems are presented that include breaking or making contact with the environment, in addition to the conventional reflex and point-to-point movements. For this class of control problems, available mathematical methods of maintaining or breaking the support are surveyed, and these results are expressed in the context of experimental tests and results about the functional role of the support forces in stability and the role of skin mechanoreceptors in sensing and processing of these forces. The existence, role, and source of a network of gain controlling mechanisms?the facilitatory-inhibitory system?is reviewed. A gross locomotion model of the central nervous system is presented where the extrapyramidal pathway is modeled with a kinematic model, an inverse system, and a feedback system. These three subsystems correspond, respectively, to the lateral cerebellum, the basal ganglia, and the vermal and/or paravermal cerebellum.
Well-log tomography and 3-D imaging of core and log-curve amplitudes in a Niagaran reef, Belle River Mills field, St. Clair County, Michigan, United States

Well-log tomography, a recently developed technique that generates subhorizontal slices through log curves, was used to create a series of amplitude slices from the core permeability, core porosity, and gamma-ray log curves for the wells penetrating the Silurian Brown Niagara reservoir in the Belle River Mills field. Log-curve amplitude slicing and three-dimensional (3-D) imaging of the core permeability and core porosity amplitudes show the detailed anatomy of the pinnacle reef in terms of these important reservoir properties. Although the reef has been dolomitized, the spatial distribution of permeability and porosity amplitudes in the reservoir appears to be controlled by the original pore and depositional fabrics of the wackestone, boundstone, stromatolite, and reef conglomerate rock types.Trends and patterns observed in the normalized gamma-ray log tomography approximate the trends and patterns observed in the core permeability and core porosity tomography in the Belle River Mills field. The similarities in the tomography trends and patterns establishes a potentially significant relationship that can be used to interpret log-curve amplitude patterns in other Niagaran pinnacle reef fields with log-curve data only and perhaps lead to improved sequence-stratigraphic models for these reservoirs.Well-log tomography and 3-D imaging provide complementary visualization tools that use existing data to image reservoirs and geologic formations. These imaging tools can be used to improve the design and placement of vertical, deviated, and horizontal wellbores for primary, secondary, tertiary, and gas storage operations in these reefs and other reservoirs.
Carbon-Coated Tellurium for Optical Data Storage

A highly durable optical disk has been developed for data archiving. This optical disk uses tellurium as the write layer and carbon as a dielectric and oxidation prevention layer. The sandwich style CTeC film was deposited on polycarbonate and silicon substrates by plasma sputtering. These films were then characterized with AFM, SEM, TEM, EELS, and ellipsometry and were tested for writability and longevity. Results show the films were uniform in physical structure, stable, and able to form permanent pits. Data was written to a disk and successfully read back in a commercial DVD drive.
Minimum annual survival estimates of male Cerulean Warblers (setophaga cerulea) in southwestern Michigan

Abstract The Cerulean Warbler (Setophaga cerulea) is a North American landbird showing a high rate of population decline. Estimates of its annual adult survival rate are needed to evaluate its current population status. Annual return rates of 104 color-banded adult male Cerulean Warblers were used to estimate minimum annual survival from 2008–2011. The study site was a large oak-hickory forest bordered by a mosaic of forest tracts and agricultural land in southwestern Michigan. Cormack-Jolly-Seber (CJS) live recapture models yielded an annual survival estimate (Φ) of 0.59. This estimate lies in the range of available CJS survival estimates for other Neotropical migratory species with different population trajectories. In addition, this survival value confirms sink population status for Cerulean Warbler breeding populations studied at widespread locations in the breeding range (all λ < 1.0). Inter-year breeding dispersal was frequently <1.0 km, but seven banded males made breeding dispersal movements among...
Extended Operation of Cascade Multicell Converters Under Fault Condition

Multilevel converters are an interesting alternative for high power drives, due to their good quality output signals. Despite their advantages, the large number of components required increases the fault probability. Among the multilevel topologies, the cascade multicell converter presents advantages when operating under internal fault conditions, due to its high modularity. Previous works proposed to compensate the unbalanced operation due to a fault by changing the canonical fundamental output phase shift to precalculated angles, depending on the fault condition. This solution assumes that, if the maximum output phase voltage on each leg is used, the maximum line-to-line voltage will be at a maximum as well. This paper shows how this assumption is not always valid and presents the optimum angles and modulation indexes that must be used in order to obtain the maximum balanced load voltages.
Women's cognitive health: postmenopausal dementia and the women's health initiative memory study.

t d a c f S y 2050, it is estimated that 13 million Americans will have Alzheimer disease (AD) (Hebert, Scherr, ienias, Bennett, & Evans, 2003). Milder cognitive mpairment affects between one fifth and one third of lder adults (Lopez, Jagust, DeKosky, et al., 2003) and redicts dementia and subsequent institutionalization Fisk, Merry, & Rockwood, 2003). Medications have een developed specifically for the treatment of cogitive decline, but their benefit has been more modest han hoped for. A better understanding of risk factors or cognitive impairment, as well as treatments to meliorate the condition, is an important public health riority. Postmenopausal women appear to have a greater isk of developing AD than men (Payami, Montee, rimlid, Shattuc, & Kaye, 1996). One explanation elates to women’s lower endogenous estrogen levels fter menopause (Paganini-Hill & Henderson, 1994). nitially, a positive association between exogenous strogen and cognitive performance in nondemented lder women was consistently reported (e.g., Kawas et l., 1997; Maki & Resnick, 2000; Phillips & Sherwin, 991). In addition, meta-analyses of estrogen’s potenial protective effects against dementia found risk eductions of 29% (Yaffe, Sawaya, Lieberburg, &
Study of magnetic tunnel junction read sensors

Unshielded magnetic tunnel junction (MTJ) sensors stabilized by insulating hard magnetic tails have been fabricated. Testing results showed that the control of oxidation condition was important for obtaining MTJ with low junction resistances and high TMR coefficients. The results also showed that the thickness of insulating spacer between hard magnet and MTJ stack had a significant influence on sensor stability. Finally, recording tests of stabilized MTJ read heads demonstrated linear densities of 420 Kbpi at 10/sup -9/ ontrack error.
The role of vitamins in the prevention and control of anaemia.

Objective While iron deficiency is regarded as the major cause of nutritional anaemia, changes in vitamins A, B 12 , C and E, folic acid and riboflavin status have also been linked to its development and control. This paper provides a systematic review of vitamin supplementation trials relating to the control of nutritional anaemia. Methods A MEDLINE search was used to find reports of vitamin supplementation trials that reported changes in anaemia or iron status. Results Vitamin A can improve haematological indicators and enhance the efficacy of iron supplementation. Both folate and vitamin B 12 can cure and prevent megaloblastic anaemia. Riboflavin enhances the haematological response to iron, and its deficiency may account for a significant proportion of anaemia in many populations. Vitamin C enhances the absorption of dietary iron, although population-based data showing its efficacy in reducing anaemia or iron deficiency are lacking. Vitamin E supplementation given to preterm infants has not reduced the severity of the anaemia of prematurity. Vitamin B 6 effectively treats sideroblastic anaemia. Multivitamin supplementation may raise haemoglobin (Hb) concentration, but few studies have isolated the effect of multivitamins from iron on haematological status. Conclusions In general, the public health impact of vitamin supplementation in controlling anaemia is not clear. Neither are the complex interactions involving multiple vitamins in haematopoiesis sufficiently understood to explain the observed variability in haematological responses to vitamins by age, population, vitamin mixture and dosages. Further research is needed to understand the roles of individual and combined vitamin deficiencies on anaemia to design appropriate micronutrient interventions to prevent anaemia.
De novo neurogenesis and acute stroke: are exogenous stem cells really necessary?

RECENT STUDIES DOCUMENTING the phenomenon of de novo neurogenesis within the adult brain have propelled this area of research to the forefront of neuroscience investigations and stroke pathogenesis and treatment. Traditional theories have suggested that the central nervous system is incapable of neural regeneration; hence the emergence of the field of stem cell biology as a discipline devoted to uncovering novel forms of neural repair. However, several recent experimetal observations have shown that the adult brain is capable of ongoing neurogenesis in discrete regions of the unidijured brain and addisional forms of endogenous neural regeneration in the presence of an inciting event (induction neurogenesis). Unducation neurogenesis has the potential for providing new insights into the cause and treatment of acute stroke syndromes.
A Captcha Based on the Human Visual Systems Masking Characteristics

In this paper, a CAPTCHA is presented based on the masking characteristics of the Human Visual System (HVS). Knowing that noise can be masked by high activity regions and showing that edges can be masked by noise for a human observer while still being detected by machines, the suggested CAPTCHA is composed of English alphabets that are picked randomly and written with a combination of texture and edges with added noise such as to deceive the machine by randomly changing the visibility of characters for humans. The proposed CAPTCHA is highly legible and robust to brute-force attacks and sophisticated Object Character Recognition (OCR) segmentation algorithms.
Analyze-NOW-an environment for collection and analysis of failures in a network of workstations

This paper describes Analyze-NOW, an environment for the collection and analysis of failures/errors in a network of workstations. Descriptions cover the data collection methodology and the tool implemented to facilitate this process. Software tools used for analysis are described, with emphasis on the details of the implementation of the Analyzer, the primary analysis tool. Application of the tools is demonstrated by using them to collect and analyze failure data (for 32-week period) from a network of 69 SunOS-based workstations. Classification based on the source and effect of faults is used to identify problem areas. Different types of failures encountered on the machines and network are highlighted to develop a proper understanding of failures in a network environment. The results from the analysis tool should be used to pinpoint the problem areas in the network. The results obtained from using Analyze-NOW on failure data from the monitored network reveal some interesting behavior of the network. Nearly 70% of the failures were network-related, whereas disk errors were few. Network-related failures were 75% of all hard-failures (failures that make a workstation unusable). Half of the network-related failures were due to servers not responding to clients, and half were performance-related and others. Problem areas in the network were found using this tool. The authors' approach was compared to the method of using the network architecture to locate problem areas. This comparison showed that locating problem areas using network architecture over-estimates the number of problem areas.

THe Effects of Discontinuous Change on Latent Errors in Organizations: The Moderating Role of Risk

Internal audit data of operations in a financial institution were used to examine the effects of discontinuous change and work-inherent risk on latent errors, defined here as potentially consequential deviations from procedures and policies. Results show that discontinuous change increases latent errors and that this increase varies with the level of risk. Implications for organizational research on errors and reliability are discussed.
Can bycatch in a flatfish gillnet fishery be reduced with rectangular mesh

Gillnets fished in North Carolina, USA, estuaries have high rates of bycatch relative to the target catch of southern flounder, Paralichthys lethostigma Jordan & Gilbert. This study tested whether rectangular-mesh gillnets would maintain catch rates of southern flounder and reduce fish bycatch relative to conventional diamond-mesh gillnets in two North Carolina estuaries. In the Neuse River estuary, catch rates of legal southern flounder were not different between the two mesh shapes, but the bycatch of red drum, Sciaenops ocellatus (Linnaeus) and other fish species was reduced with rectangular-mesh net. In the Newport River estuary, southern flounder and red drum catches were reduced in rectangular-mesh net, but the decrease was greater for red drum. Catches of sublegal southern flounder were reduced in the rectangular-mesh net in both estuaries. Reduced catch rates of sublegal southern flounder and bycatch species suggest rectangular mesh may help manage stocks of estuarine fish species in areas where gillnets are used to target flatfishes.
Energetic Particle from CME-Driven Shocks: Spectra, Composition, and Timing

Very large solar energetic particle (SEP) events occur at the rate of about 10 per year during solar maximum. The primary accelerators in these events are shocks driven by fast coronal mass ejections, in which speeds are greater than about 1000 km/s. Solar Cycle 23 probably produced the largest fluence of >10 MeV/nucleon SEPs seen since the start of the Space Age. New instruments on Wind, ACE, SOHO, and other satellites have provided unprecedented detail on the energy spectra, elemental and isotopic composition, ionic charge states, and temporal evolution of these SEP events, as well as their associated CMEs and flares. In this talk, I will review some of the new insights provided by these data. A particular challenge in SEP studies has been the very large event-to-event variability in composition and spectral characteristics, particularly at energies above a few tens of MeV per nucleon. I will discuss recent efforts to understand this variability in terms of seed populations and shock geometry. I will also review recent studies of the time at which SEPs first appear on the Sun-Earth magnetic field line and the implications of these studies for the conditions under which SEP production was initiated.
Management Style and the Organizational Matrix Studying White House Operations

Scholars and journalists have devoted a wealth of attention to White House organization and management, but have produced only modest conclusions on how presidential staffing is related to performance. This article assesses findings from two schools of staffing studies—personalist and institutionalist—and suggests that re-searchers ultimately need to examine the interactive effects of management style and organizational factors on performance. To this end, a typology is developed based on two dimensions of variation: a president's managerial assertiveness and staff cohesion. The four resulting patterns are discussed in terms of the nine most recent administrations.
A first year computer organization course on the web: make the magic disappear

This paper describes a freshman-level computer organization course designed to remove the magic surrounding the operation of modern computer systems. Students in the course use a virtual machine with a graphical interface (simulating a processor named TSC) to develop assembly language programming skills. They then use digital design techniques to implement TSC and run their programs on it. We have found the course to be successful in bringing the students full circle, showing how binary instructions and simple gates can lead to a working computer system. A text has been written to integrate the lecture topics and the labs. The text, labs, and software tools have been made available on the Web.
Palliative and Supportive Care for Renal Cancer

Advancements in the treatment of renal cell carcinoma have allowed patients to live longer. However, most patients experience a multitude of symptoms associated with their advanced malignancy and these targeted therapies. Symptom management challenges are becoming more common. Poorly managed symptoms adversely affect patients’ overall function and quality of life. Integrating palliative and supportive care throughout the spectrum of the illness will greatly improve patient care and satisfaction. This chapter focuses on some of the commonly reported symptoms in advanced renal cell cancer such as pain, cancer anorexia–cachexia, and cancer- and treatment-related fatigue, and offer recommendations on management.
An actively controlled control moment gyro/gyropendulum testbed

An experimental testbed for investigating control algorithms for reducing or eliminating the effects of mass imbalance in rotating bodies has been designed and constructed. This control moment gyro/gyropendulum testbed allows researchers to experimentally demonstrate control algorithms for reorientation, stabilization and vibration suppression.
Immortality and The Modern Temper: The Ingersoll Lecture, 1961

In the following reflections I shall start from what I consider an undeniable fact, namely, that the modern temper is uncongenial to the idea of immortality. It is that over and above the objections which the modern intellect entertains against it on theoretical grounds. These — which for brevity I will simply grant en bloc — are by themselves indecisive. As transcendental, the object of the idea — immortality itself — is beyond proof or disproof: it is not an object of knowledge. But the idea of it is. Therefore, the intrinsic merits of its meaning become the sole measure of its credibility, and the appeal of such meaning remains as the sole ground of possible belief — as certainly the lack of such appeal is sufficient ground for actual disbelief. But since what is meaningful depends, beyond the mere condition of logical consistency, largely on the dispositions and insights of the mind that judges it, we must interrogate these for their prevalent unresponsiveness as well as for any possible hold which the idea, even in its present eclipse, may still have, or reclaim, on our secularized estate. Thus an examination of the problem at this hour will be as much an examination of ourselves as an examination of the issue of immortality; and even if it should throw no new light on the latter, on which in more than two thousand years probably everything has been said there is to say, it may yet throw some light on the present state of our mortal condition.
HOME RANGE AND NEST USE OF THE GOLDEN MOUSE (OCHROTOMYS NUTTALLI) IN SOUTHERN ILLINOIS

To estimate home range and ascertain nesting habits of golden mice (Ochrotomys nuttalli), 19 individuals were radiocollared and their nests located. Individual home-range area did not significantly vary with sex, season, or number of nests used; minimum convex polygon and adaptive kernel estimates ranged from 0.18 to 1.33 ha and from 0.33 to 2.82 ha, respectively. Home-range overlap among individuals was considerable. No difference existed in distances between nests used by the same individual. Females used more arboreal nests; males used more ground nests. Only males exclusively used ground nests. Significant variables associated with placement of both ground and arboreal nests were distance to nearest vines and undergrowth, densities of herbaceous and woody stems, and density of understory ,0.5 m at 1 m from the nest. Depth of leaf litter and size (dbh) of nearest tree also predicted placement of ground nests. Density of understory, 1.6‐2.0 m high, and number of herbaceous stems significantly predicted placement of arboreal nests. The golden mouse may be less of a habitat specialist than believed. Management for invasive or early successional plant species may enhance habitat for this species.
Women in Thoracic Surgery: 30 Years of History

Women in Thoracic Surgery was founded in 1986, with 2016 marking its 30th anniversary. Reflecting back on the last 3 decades of history, accomplishments, and enormous strides in our field, we review the past, present, and future of this organization. Although women still constitute a small minority of practicing surgeons in our field today, opportunities currently abound for women in thoracic surgery. Owing much to the early female pioneers in the field and to the support of male sponsors and our national societies, Women in Thoracic Surgery has grown and prospered, as have its members and the global community of female thoracic surgeons as a whole. In celebration of our 30th anniversary, we share with the readership the rich history of Women in Thoracic Surgery and its goals for the future.

Integrating Vision and Touch for Grasping of an Object

The aim of this paper is to present considerations that go into the design of a system that will be able to grasp a variety of objects. Grasping depends on the assumption of two properties: The shape and size of the three-dimensional object and on the task that follows after grasping; hence, our interest in the integrated approach to 3-D shape recognition. We shall present an overview of currently available and being developed algorithms for representation and recognition of three-dimensional shape of an object as perceived by visual and/or tactile sensors. For the visual sensor we assume that we have available stereo cameras or their equivalent. As the tactile sensor we use an articulated multifingered hand equipped with tactile sensory arrays as the data acquisition device. We shall present available configurations of these devices. Then we shall investigate the sensory processing, in particular, what representation schemas should be considered. We shall argue that the object-centered representation as opposed to observer-centered representation is more important for grasping. Finally, a rule based schema for the control strategies will be outlined. As examples, first some artificial geometric objects then some real laboratory objects from the blocks world will be analyzed.
Aerobic and Anaerobic Thiosulfate Oxidation by a Cold-Adapted, Subglacial Chemoautotroph

Geochemical data indicate that protons released during pyrite (FeS2) oxidation are important drivers of mineral weathering in oxic and anoxic zones of many aquatic environments, including those beneath glaciers. Oxidation of FeS2 under oxic, circumneutral conditions proceeds through the metastable intermediate thiosulfate (S2O3 (2-)), which represents an electron donor capable of supporting microbial metabolism. Subglacial meltwaters sampled from Robertson Glacier (RG), Canada, over a seasonal melt cycle revealed concentrations of S2O3 (2-) that were typically below the limit of detection, despite the presence of available pyrite and concentrations of the FeS2 oxidation product sulfate (SO4 (2-)) several orders of magnitude higher than those of S2O3 (2-). Here we report on the physiological and genomic characterization of the chemolithoautotrophic facultative anaerobe Thiobacillus sp. strain RG5 isolated from the subglacial environment at RG. The RG5 genome encodes genes involved with pathways for the complete oxidation of S2O3 (2-), CO2 fixation, and aerobic and anaerobic respiration with nitrite or nitrate. Growth experiments indicated that the energy required to synthesize a cell under oxygen- or nitrate-reducing conditions with S2O3 (2-) as the electron donor was lower at 5.1°C than 14.4°C, indicating that this organism is cold adapted. RG sediment-associated transcripts of soxB, which encodes a component of the S2O3 (2-)-oxidizing complex, were closely affiliated with soxB from RG5. Collectively, these results suggest an active sulfur cycle in the subglacial environment at RG mediated in part by populations closely affiliated with RG5. The consumption of S2O3 (2-) by RG5-like populations may accelerate abiotic FeS2 oxidation, thereby enhancing mineral weathering in the subglacial environment.
Exploring photobios

We present an approach for generating face animations from large image collections of the same person. Such collections, which we call photobios, sample the appearance of a person over changes in pose, facial expression, hairstyle, age, and other variations. By optimizing the order in which images are displayed and cross-dissolving between them, we control the motion through face space and create compelling animations (e.g., render a smooth transition from frowning to smiling). Used in this context, the cross dissolve produces a very strong motion effect; a key contribution of the paper is to explain this effect and analyze its operating range. The approach operates by creating a graph with faces as nodes, and similarities as edges, and solving for walks and shortest paths on this graph. The processing pipeline involves face detection, locating fiducials (eyes/nose/mouth), solving for pose, warping to frontal views, and image comparison based on Local Binary Patterns. We demonstrate results on a variety of datasets including time-lapse photography, personal photo collections, and images of celebrities downloaded from the Internet. Our approach is the basis for the Face Movies feature in Google's Picasa.
Thermal-reactor lattice analysis using ENDF/B-IV data with Monte Carlo resonance reaction rates

Uranium fueled thermal-reactor lattice benchmarks, as well as some other experimental assemblies, were analyzed with ENDF/B-IV data and calculational techniques based on integral transport and SN methods together with Monte Carlo calculations in the resolved resonance region. Only a relatively small overprediction of the $sup 238$U resonance events--3 to 4 percent--remains when the present version of the ENDF/B data is used. It accounts for a considerable part of the 1 percent underprediction of criticality. Uranium-235 resonance absorption was found to be influenced noticeably by shielding due to the $sup 238$U resonances. For both $sup 235$U epithermal and $sup 238$U fast fissions, the agreement between calculation and experiment, although relatively good, showed greater fluctuations than in the case of the $sup 238$U capture. Calculated temperature variations of material buckling with temperature were greater than in the measurements, especially near room temperature, but the discrepancies were smaller in the critical than in the exponential assemblies.

Isolated autism is not an indication for SLO testing

Study Smith-Lemli-Opitz (SLO) syndrome is an autosomal recessive disorder of cholesterol synthesis due to deficiency in 7-dehydrocholesterol (7-DHC) reductase. SLO is associated with specific dysmorphology, microcephaly, syndactyly, cleft palate, growth retardation, genital ambiguity and intellectual disability with autistic features. The autistic features respond to cholesterol supplementation. Increased levels of 7-DHC are a marker for SLO and routinely used for testing of autistic children. Methods A total of 5 years of requests for 7-DHC testing at S A Pathology were audited (2008-2012). Data were broadly classified according to clinical indications, including isolated autism, developmental delay, seizure, dysmorphism, neurological, anatomic, genital or metabolic anomalies. Data were sub-classified as single or multiple clinical indication/s or no clinical information supplied. Results 809 tests were performed and 16 cases of SLO were detected. No cases of SLO were diagnosed based on an isolated clinical indication of autism or where no clinical information was supplied. Discussion Experience of several years of 7-DHC testing at SA Pathology indicates that autism as an isolated clinical trait is not associated with SLO. 7-DHC measurement should not be included in the testing panel when autism spectrum disorders are the only clinical indication.

Clinoptilolite-Heulandite Nomenclature

Heulandite was first named in 1822 for the English mineral collector, J. H. Heuland (see Dana 1914, p. 574–576). Although it is typically found as macroscopic (commonly 0.2–2 cm in size) crystals in cavities in mafic igneous rocks and is volumetrically minor on the Earth’s surface, heulandite also occurs in larger amounts in some sedimentary deposits, often in association with clinoptilolite. Due to the large size of typical heulandite crystals, its chemical composition and crystallographic and optical properties were easily characterized. Mineralogists recognized early that heulandite is monoclinic and that heating changes its optical properties in a predictable manner (Slawson 1925). Unlike heulandite, the mineral known today as clinoptilolite typically occurs as microscopic crystals, commonly 2–20 μm in size and commonly intimately admixed with other fine-grained minerals. Although clinoptilolite is known today as the most common natural zeolite, occurring in large amounts (millions of tons) in altered volcanic tuffs and saline, alkaline-lake deposits, it is generally mentioned only in passing in beginning mineralogy texts. Clinoptilolite was not described as a distinct mineral species until 1932 (Schaller 1932). Prior to that time, the platy material described by Pirsson (1890) in amygdules in weathered basalt from the Hoodoo Mountains, Wyoming, had been classified as “mordenite,” based primarily on its chemical similarity with mordenite from Nova Scotia. In spite of the chemical similarities, Pirsson did recognize the crystallographic similarity between the Wyoming “mordenite” and heulandite. Dana’s sixth edition (1914, p. 572–573) lists both ptilolite and mordenite as members of the mordenite group. Ptilolite (which we now recognize as mordenite) is listed by Dana as commonly occurring in aggregates of needles having parallel extinction, but “mordenite” is reported by Dana to be monoclinic, having a form closely approximating that of heulandite. Schaller (1932) proposed the name clino ptilolite based on the chemical …

Abstract 1617: Chebulagic acid can inhibit vascular endothelial growth factor-A mediated angiogenesis.

Proceedings: AACR 104th Annual Meeting 2013; Apr 6-10, 2013; Washington, DC Background: Angiogenesis or new blood vessel formation is essential for the growth, progression and metastasis of malignant tumors. Among the several pro-angiogenic factors, vascular endothelial growth factor-A (VEGF-A) plays a critical role in this process of angiogenesis. However, the current anti-VEGF-A agents in the clinics are not only expensive, but also have serious side effects. Therefore it is essential to identify newer, effective, less toxic and inexpensive anti-VEGF-A agents for the treatment of cancer. We have recently demonstrated the anti-VEGF-A actions of Triphala churna (THL), a natural medicinal product prepared from three myrobalan fruits. Because chebulagic acid (CA), a bioactive tannin present in THL has been reported to inhibit tumor growth, we therefore investigated the effect of CA on VEGF-A mediated angiogenesis. Method: Human umbilical vein endothelium cells (HUVECs) were cultured in vitro, and pre-treated with different doses of CA for 24hrs. Thereafter, we examined the proliferation migration and tube formation abilities of these cells. In addition we also determined the effects of CA on HUVEC cell permeability and on new blood vessel formation utilizing CAM assay. Finally, the effect of CA on VEGFR-2 phosphorylation was investigated. Results: 5uM CA can significantly inhibit VEGF-A induced cell proliferation, migration and permeability of HUVECs. Besides it can also inhibit formation of tube-like structures by these cells. In vivo CAM assay also suggested that 5uM CA can suppress VEGF-A stimulated new vessel formation. Western blot confirmed that CA inhibits VEGF-A actions by suppressing phosphorylation of VEGFR-2. Conclusion: Our findings suggest that CA can significantly inhibit VEGF induced angiogenesis.

Malignancy complicating endometriosis: Pathologic features in 9 cases

Abstract Cases have been presented in which carcinoma apparently originated from the lesions of both internal and external endometriosis. I believe that such a complication occurs much more frequently than is indicated by this type of sampling, in which actual proof of the sequence is unquestioned. Although endometriosis can often be diagnosed from pelvic examination, in patients over 40 years of age it is unwise to regard an adnexal mass as representing benign endometriosis until this is proved by surgical exploration.
[Epidemiologic characteristics of typhoid and paratyphoid fever on related drug resistance and molecular types regarding Salmonella typhi and S. paratyphi, in Jiangsu province].

Objective To explore the distribution of prevalence rates of typhoid and paratyphoid,with drug resistance and molecular types ofSalmonella(S.) typhi and S.paratyphi in Jiangsu province.Methods Data,collected by the national infectious disease reporting system in Jiangsu province from 2007 to 2011,was analyzed.K-B method was used to test the sensibility to 9 kinds of antibiotics among 210 stains of S.typhi and S.paratyphi.81 strains of S.typhi were classified by pulse-field gel electrophoresis (PFGE).Results The annual average incidence of typhoid and paratyphoid was 0.47 per 100 000 in the last five years,showing a decreasing trend.Highest incidence (1.70 per 100 000)was seen in the ＜ 1 year age group,with S.typhi and S.paratyphi A accounted for 66.19％ and 23.81％ among the 210 stains.The rate of drug resistance to nalidixic acid appeared to be the highest as 66.19％.The drug resistant rates to 6 kinds of antibiotics were on average,lower than 10.00％.The multi-drug resistant rate of S.typhi and S.paratyphi was 30.00％.In the last 3 years,37 types from 81 S.typhi strains had been classified into 4 clusters by PFGE.The predominant type was JPPX01.JS0027,accounted for 11.11％.JPPX01.JS0001 type had a specific regional distribution,but JPPX01.JS0014,JPPX01.JS0018 and JPPX01.JS0024 strains were widely spread.Results from the clustering analysis showed that cases in the 3 events tended to have a clustering nature.Conclusion The morbidity of typhoid and paratyphoid was in a relatively low level in Jiangsu province.Although S.typhi and S.paratyphi were sensitive to most of the commonly used antibiotics,the resistance rates to some kinds of antibiotics were increasing.The distribution of typhoid was sporadic in Jiangsu and without the dominant strain,it was unlikely that typhoid could become epidemic in the future,in Jiangsu.

I discuss the extraction of V ub from the hadronic mass spectrum in the semileptonic decay B → X u lv. It is stressed that an accurate determination requires independent information about the hadronic parameter \(\bar \Lambda = {m_B} - {m_b}\).
Cardiac Gαs and Gαi Modulate Sympathetic Versus Parasympathetic Mechanisms in Hyperhomocysteinemia

The increase in sympathetic activity is a compensatory mechanism that provides inotropic support to the heart and peripheral vasoconstriction. Increased sympathetic nerve activity is associated with chronic heart failure (CHF). Increased sympathetic nervous activity activates NMDA receptors and GPCRs, which results in the physiological effect of cardiac arrhythmias. It is clear that GPCR activation feeds into the NMDA receptor signal transduction axis, and heightens the physiological effect of cardiac arrhythmias. Effectors that modulate GPCR activation also physically modify the NMDA receptor via intracellular tyrosine kinases. However, it is unknown whether homocysteine-induced NMDAR activation can backtalk to GPCRs and modulate G-proteins: Gαs, Gαi. This bidirectional crosstalk to GPCRs may be mediated by a number of possible events; perhaps calpain or members of the MAPK cascade that includes ERK 1/2 and MMP-9, or even reactive oxygen species may feed back to GPCRs and potentiate G-proteins. Or, perhaps the influx of calcium from NMDAR activation may somehow activate the GPCR signal transduction axis, including G-proteins. Our specific interest begins in knowing exactly whether homocysteine-induced activation of NMDAR can backtalk to GPCRs and modulate G-proteins-Gαs, Gαi-before beginning to elucidate the players that modulate this kind of backtalk. This review addresses the following: pathophysiology of CHF and sudden cardiac death (SCD), causes of cardiac arrhythmias (electrical and structural remodeling), the relationship between homocysteine and CHF, homocysteine and NMDAR activation, the NMDAR signal cascade, GPCR signal cascade, NMDA-to-GPCR crosstalk, and proposal for homocysteine-induced NMDAR and GPCR bidirectional crosstalk that modulates G-proteins.

Discordance in selected designee for return of genomic findings in the event of participant death and estate executor

Background Legal and ethical questions arise regarding disseminating genetic research results to family members in the event of a research participant's death; failure to return or return to legal next of kin or estate executor may not reflect participant desires. We sought to determine participant preferences for whether and to whom they would like their data released in the case of their death prior to receiving genomic results, focusing on whether the person selected was also their estate executor. Methods The University of Washington NEXT Medicine Study of the Clinical Sequencing Exploratory Research program previously reported participant preferences regarding designating an individual to receive genomic results in the event of death, including whether they want results shared, and if so, with what person. Participants were also asked whether this designee is executor of their will or estate. Results To date, 61 individuals were asked about the concordance of their study designee and legal representative: 42 (69%) reported having a will or estate plan and of these, 14 (33%) chose someone other than their executor to receive their results. For the 14 who chose someone other than their estate executor to receive genetic results, 12 (86%) chose a family member, typically a biological relative, as their designee. Those with a different genomic designee than their executor were less likely to be partnered (P = 0.0024). For those partnered participants without an estate plan, spouses were not always chosen for return of genomic results. Conclusion For one-third of our participants, the individual deemed most appropriate by the participant to receive their genomic results was not the executor. In the absence of an explicit designation, HIPAA may prohibit access to genomic results to persons other than the executor; hence asking for designation at the time of study enrollment (or initiation of clinical testing) is important.
Decomposition theorems for Qp spaces

We study the Mobius invariant spacesQ p andQ p, 0 of analytic functions. These scales of spaces include BMOA=Q 1, VMOA=Q 1, 0 and the Dirichlet space=Q 0. Using the Bergman metric, we establish decomposition theorems for these spaces. We obtain also a fractional derivative characterization for bothQ p andQ p, 0 .
