Mechanism of the dicrotic pulse.
Creators: name: Smith, Damon
name: Craige, Ernest
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: The dicrotic pulse is an abnormal carotid pulse found in conjunction with certain conditions characterised by low cardiac output. It is distinguished by two palpable pulsations, the second of which is diastolic and immediately follows the second heart sound. In the course of open chest canine studies of the second heart sound, micromanometers and an electromagnetic flow meter were used to study proximal aortic haemodynamic function in both strong and weak beats. It was found that the incisural notch of the aortic pressure signal is not strongly dependent on the extent of left ventricular ejection, and is of essentially normal amplitude even in beats having greatly reduced aortic flow. In contrast, the magnitude of the systolic upstroke of the aortic pressure pulse is strongly determined by the magnitude of left ventricular ejection and is considerably reduced in weak beats. With low cardiac output the relative size of the incisural notch becomes exaggerated in comparison with the overall pulsation, thus creating the characteristic M shaped waveform of the dicrotic pulse.

description: This paper examines the transliteration of the ancient Italic name Iove, referring to Jupiter, into ancient Hebrew. By analyzing the phonetic elements of the name and the orthographic characteristics of both Latin and Hebrew, we propose an approximation of how Iove would have been represented in ancient Hebrew script. Additionally, we explore the theoretical shift from "Yohweh" to “Yahweh,” comparing it to existing transliterations like YHWH and Jehovah.

description: The Omega-deformation is a harmonic trap, penning certain excitations near the origin in a manner consistent with supersymmetry. Here we explore the dynamics of BPS monopoles and vortices in such a trap. We pay particular attention to monopoles in the Higgs phase, when they are confined to a vortex string. Unusually for BPS solitons, the mass of these confined monopoles is quadratic in the topological charges. We compute an index theorem to determine the number of collective coordinates of confined monopoles. Despite being restricted to move on a line, we find that they have a rich dynamics. As the strength of the trap increases, the number of collective coordinates can change, sometimes with constituent monopoles disappearing, sometimes with new ones emerging.

MANAGEMENT OF CARDIOGENIC SHOCK COMPLICATING ACUTE MYOCARDIAL INFARCTION
Creators: name: Hochman, Judith S.
name: Menon, Venu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: The incidence of cardiogenic shock in community studies has not decreased significantly over time. Despite decreasing mortality rates associated with increasing utilisation of revascularisation, shock remains the leading cause of death for patients hospitalised with acute myocardial infarction (MI). Although shock often develops early after MI onset, it is typically not diagnosed on hospital presentation. Failure to recognise early haemodynamic compromise and the increased early use of hypotension inducing treatments may explain this observation.

description: Seven days on a protein-free diet increases the susceptibility of rats to the action of DMN as a renal carcinogen. The dose response for the induction of kidney tumours by a single dose of dimethylnitrosamine (DMN) in these rats is reported. The first tumour was not found until 28 weeks after the dose. At 100 weeks the incidence ranged from 22.5% at the lowest dose (20 mg/kg) to 97% at the highest dose (60 mg/kg). The incidence in probits at any time between 50 and 100 weeks was linearly related to the log dose. Epithelial and mesenchymal tumours were produced in an approximate ratio of 2:1. The protein-free diet alters the rate of metabolism of DMN in the rat, and increases the alkylation of nucleic acids by this carcinogen in the kidney. Further treatment of the rat with benzo(a)pyrene can reverse, to some extent, the change in metabolism, but does not reverse the change in alkylation. It is shown that the change in kidney-tumour incidence produced by the change in diet, and by the treatment with benzo(a)pyrene, corresponds to the changes these treatments produce in the alkylation of kidney DNA by the carcinogen.

description: This paper describes how implementation of data discovery and access services that comply with Virtual Observatory (VO) standards also provide compliance with the "FAIR Guiding Principles for scientific data management and stewardship", published in 2016. The VO standards are developed by the International Virtual Observatory Alliance (IVOA; http://ivoa.net)), an international collaboration of 22 nationally-organized VO projects. The IVOA was founded in 2002 to foster discovery of, and access to worldwide astronomy databases through a common set of interfaces. The goal of the IVOA from the outset was to enable seamless interoperability of open data and services; as such it was implementing what became know as FAIR principles before they were formalized. The IVOA has by now developed of a mature set of standards, and VO compliant services underpin the architectures of all major astronomy archives. Generally, IVOA standards published make data almost FAIR: of the 15 items in the breakdown of the four major FAIR principles, IVOA standards meet all but four of them (though the most recent standards, such as the VO data model, do not yet have universal deployment). The four noncompliant items are in areas that are considered out of scope for the IVOA. An example is licensing, which is left for data providers. Among the IVOA standards, the Simple Line Access Protocol (SLAP) deals with spectroscopic line lists. One of the main goals is to allow astronomers to discover, through the Virtual Observatory, archived spectra and to easily identify the observed absorption and emission lines in the spectra by queries in line list databases. SLAP was introduced at the IVOA in 2010. A more modern access protocol, with better integration in the IVOA standards, is being developed thanks to, among others, VAMDC (Virtual Atomic & Molecular Data Center) developers.

description: The SIENNA project – Stakeholder-informed ethics for new technologies with high socio-economic and human rights impact (website: http://www.sienna-project.eu/) – is a European Union (EU) funded project which is part of the Horizon 2020 research and innovation programme under grant agreement no. 786641. It deals with three emerging technology areas: human genomics, human enhancement, and artificial intelligence (AI) & robotics. This report presents findings from qualitative research which involved a day-long workshop in five countries comprising three two-hour discussion sessions, with one session focused on human enhancement. The overarching aim of this qualitative research was to engage a range of citizens to consider issues raised by the three technology areas. The specific objectives for the human enhancement sessions were to briefly explore citizen views and concerns about the following types of enhancement: physical, cognitive, emotional and longevity enhancement. Workshops were held in five countries: France, Germany, Poland, Greece, and Spain. Each workshop consisted of 50-53 participants (total n= 253) including a minimum of 10 participants from pre-specified vulnerable groups. This report outlines initial participant associations with the technologies and perceived benefits and concerns for their use and provides some very early insights into what mitigation measures citizens may want to see in place to address their concerns. This qualitative research was conducted by a social research agency rather than academics. There are several important limitations to this research, which include referencing, methodological, sampling and analytical limitations. The results in this report should be read with reference to and in the context of these limitations. The results serve as indicative findings about public attitudes to this technology area and should be treated as a starting point for further academic research and analysis to build from. They should not be read in isolation and should be read with reference to the other reports that have been produced as part of the SIENNA project. One of the main findings from the research was that participants did not understand that human enhancement technologies refer specifically to improving the capabilities of ‘healthy’ human beings beyond what is deemed ‘normal’. Instead, they often combined references to health treatments and enhancement, seemingly not distinguishing between them. As such, across the four enhancement areas discussed, participants felt that the main benefits of new technologies revolved around healthcare and focused on clinical applications in their discussions. HET areas also raised various concerns, which can be grouped in two categories: individual concerns and societal concerns.

description: Malignant effusions and tumour tissue obtained at surgery provided material for a study of the prognostic value of the various inflammatory cells in the prognosis of human ovarian cancer. Ascitic fluids predominantly contained inflammatory cells; tumour cells, both singly and in clusters, were a minor component. Tumour cells were usually in excess in dispersed solid material. Some patients had significant proportions of lymphocytes and macrophages in their solid tumour, and these patients invariably responded to therapy. Sedimentation-velocity separation at unit gravity provided tow populations of inflammatory cells. One consisted of mononuclear cells similar in size to those in the patients blood: the other consisted of one or more large macrophage populations, distinct in morphology and enzymatic markers from both blood monocytes and each other. T lymphocytes were enriched in ascites fractions (78%) and in the tumour-derived mononuclear fraction (71%) compared to patient blood (60%). The T-cell subset characterized by ANAE reactivity was markedly depleted in the tumour-infiltrating fraction (17%) compared to patient blood (62%) or patient blood (51%). Esterase-positive monocyte-like cells were more frequent in the tumour-infiltrating fraction (17%) than ascites (7%) or blood (12%). B lymphocytes were infrequent in solid tumours and difficult to assess in ascites. Histiocyte-like macrophages were present in the higher-velocity tumour-cell containing fractions of both solid and ascitic material. The variation in infiltrating cells between patients and between tumour and ascites of the same individual was marked.

description: A previous case-control study which utilised the occupational information available on the New Zealand Cancer Registry found an increased risk of multiple myeloma in agricultural workers consistent with previous findings in the United States. The findings are now presented for the second phase of the study which involved interviewing 76 cases of multiple myeloma (who had been included in the previous study) together with 315 controls with other types of cancer. The previous finding on an excess of farmers in the case group was confirmed by the interview data (odds ratio = 1.7, 95% confidence limits 1.0-2.9, P = 0.04). There were no significant differences between cases and controls regarding potential exposure to phenoxy herbicides or chlorophenols. There were also no significant differences regarding activities involving potential exposure to other agricultural chemicals, although the odds ratio for fencing work, which may involve exposure to arsenic and sodium pentachlorophenate, was 1.6 (95% confidence limits 0.9-2.7, P = 0.11). The odds ratios were significantly elevated for sheep farming (odds ratio = 1.9, 95% confidence limits 1.0-3.6, P = 0.04) and exposure to beef cattle (odds ratio = 1.7, 95% confidence limits 1.0-2.9, P = 0.05). The odds ratio was also elevated for persons reporting a history of hay fever (odds ratio = 1.9, 95% confidence limits 1.0-3.5, P = 0.05). Overall, these findings suggest that the search for the causes of elevated mortality in farmers from multiple myeloma should be directed to potential causes other than pesticide exposure.
title: Immunosuppression in Atlantic salmon by an extracellular protein of Aeromonas salmonicida
Creators: name: Noor, Iffat
Publisher: name: University of Glasgow
Year: 1996
Subjects: subject: Immunology, aquatic sciences, Atlantic salmon, aeromonas.

description: The extracellular products of Aeromonas salmonicida inhibited the antibody response of Atlantic salmon to a second antigen, namely phage MS2. During the characterisation of the humoral immunosuppressive factor (HIF) evidence suggested that the suppressor was the 64-kD serine protease of A. salmonicida. Before any further work could be undertaken it was imperative to establish that the immunosuppressive action of the protease was not merely due to proteolytic degradation of the antibody molecule. This was shown not to be the case by both in vivo and in vitro experiments. Further, it was also illustrated that MS2 phage used as the second antigen was also not degraded by the protease and that the antibody response elicited in fish was specific for the phage. The effect of the protease on the proliferation of leucocytes from peripheral blood and anterior kidney was investigated and it was shown that the protease caused a dose related inhibition of the cell stimulation in response to the B cell mitogen, LPS. This effect was enhanced when the cells were preincubated with the protease before activation with LPS suggesting that the protease may be interfering with the lymphocyte commitment to blastogenesis. The involvement of prostaglandins was implicated by in vivo experiments which showed that indomethacin, an inhibitor of prostaglandin synthesis, blocked the immunosuppressive activity of the protease when administered to fish. Subsequently, PGE2 concentration in serum samples of fish injected with indomethacin with or without protease was measured and it was clear that the protease caused an enhancement of PGE2 concentration. This result was also duplicated in in vitro experiments using leucocytes from both peripheral blood and anterior kidney which demonstrated increased levels of PGE2 in response to the protease. Furthermore, the protease stimulated an increase in the concentration of intracellular cyclic AMP of salmon leucocytes. It remains to be determined whether there is a relationship between increased levels of PGE2 and cyclic AMP stimulated by the protease. These observations indicate that the inhibitory effect of the serine protease of A. salmonicida on the humoral response of Atlantic salmon occurs via a prostaglandin-dependent pathway probably involving cyclic AMP as a secondary messenger. Although it is tentatively concluded that the suppressive factor is the 64-kDa serine protease, conclusive proof is still required. Many roles have been attributed to this protease in the pathogenesis of A. salmonicida during furunculosis in Atlantic salmon. However, its involvement in immunosuppression has not been reported before.

description: We explored the association between groundwater radon levels and childhood cancer mortality in North Carolina. Using data from two state-wide surveys of public drinking water supplies, counties were ranked according to average groundwater radon concentration. Age and sex-adjusted 1950-79 cancer death rates among children under age 15 were calculated for counties with high, medium, and low radon levels. Overall cancer mortality was increased in counties with medium and high radon levels. The strongest association was for the leukaemias, but risks were also suggested for other sites. These associations could be due to confounding or other biases, but the findings are consistent with other recent reports.

description: Altered expression of the retinoblastoma (RB) tumour-suppressor gene product (pRB) has been detected in sporadic bone and soft-tissue sarcomas. Earlier studies, analysing small cohorts of sarcoma patients, have suggested that these alterations are more commonly associated with high-grade tumours, metastatic lesions and poorer survival. This study was designed to re-examine the prevalence and clinical significance of altered pRB expression in a large and selected group of soft-tissue sarcomas from 174 adult patients. Representative tissue sections from these sarcomas were analysed by immunohistochemistry using a well-characterised anti-pRB monoclonal antibody. Tumours were considered to have a positive pRB phenotype only when pure nuclear staining was demonstrated, and cases were segregated into one of three groups. Group 1 (n = 36) were patients whose tumours have minimal or undetectable pRB nuclear staining (< 20% of tumour cells) and were considered pRB negative. Patients with tumours staining in a heterogeneous pattern (20-79% of tumour cells) were classified as group 2 (n = 99). The staining of group 3 (n = 39) was strongly positive with a homogeneous pRB nuclear immunoreactivity (80-100% of tumour cells). pRB alterations were frequently observed in both low- and high-grade lesions. Altered pRB expression did not correlate with known predictors of survival and was not itself an independent predictor of outcome in the long-term follow-up. These findings support earlier observations that alterations of pRB expression are common events in soft-tissue sarcomas; nevertheless, long-term follow-up results indicate that altered patterns of pRB expression do not influence clinical outcome of patients affected with soft-tissue sarcomas. It is postulated that RB alterations are primary events in human sarcomas and may be involved in tumorigenesis or early phases of tumour progression in these neoplasias.

description: Recently there has been remarkable progress in the complex Langevin method, which aims at solving the complex action problem by complexifying the dynamical variables in the original path integral. In particular, a new technique called the gauge cooling was introduced and the full QCD simulation at finite density has been made possible in the high temperature (deconfined) phase or with heavy quarks. Here we provide a rigorous justification of the complex Langevin method including the gauge cooling procedure. We first show that the gauge cooling can be formulated as an extra term in the complex Langevin equation involving a gauge transformation parameter, which is chosen appropriately as a function of the configuration before cooling. The probability distribution of the complexified dynamical variables is modified by this extra term. However, this modification is shown not to affect the Fokker-Planck equation for the corresponding complex weight as far as observables are restricted to gauge invariant ones. Thus we demonstrate explicitly that the gauge cooling can be used as a viable technique to satisfy the convergence conditions for the complex Langevin method. We also discuss the "gauge cooling" in 0-dimensional systems such as vector models or matrix models.

Hyperspectral Data Can Differentiate Species and Cultivars of C3 and C4 Turf Despite Measurable Diurnal Variation

description: The ability to differentiate species is not adequate for modern forage breeding programs. The measurement of persistence is currently a bottleneck in the breeding system that limits the throughput of cultivars to the marketplace and prevents it from being selected as a trait. The use of hyperspectral data obtained through remote sensing offers the potential to reduce guesswork by identifying the distribution of pasture species, but only if such data alone can distinguish the subtle differences within species, i.e., cultivars. The implementation of this technology faces many challenges due to the spectral and temporal variability of species. To understand the spectral variability between and within species groups, differentiation using hyperspectral data from monoculture plots of turf species was utilized. Spectral data were collected over a year using an ASD FieldSpec® and canopy pasture probe (CAPP). The plots consisted of monocultures of various species, and cultivars (a total of 10 plots). Linear discriminant analysis (LDA) was conducted on the full spectrum and reduced band data. This technique successfully differentiated the species with high accuracy (>98%). We demonstrate the potential of hyperspectral data and analysis techniques to accurately separate differences down to cultivar level. We also show that diurnal variation is measurable in the spectra but does not preclude differentiation.

description: We prove the existence of ballistic transport for the Schrödinger operator with limit-periodic or quasi-periodic potential in dimension two. This is done under certain regularity assumptions on the potential which have been used in prior work to establish the existence of an absolutely continuous component and other spectral properties. The latter include detailed information on the structure of generalized eigenvalues and eigenfunctions. These allow to establish the crucial ballistic lower bound through integration by parts on an appropriate extension of a Cantor set in momentum space, as well as through stationary phase arguments.

description: Motivated by understanding the emergence of thermodynamic restoring forces and oscillations, we develop a quantum-mechanical model of a bath of spins coupled to the elasticity of a material. We show our model reproduces the behavior of a variety of entropic springs while enabling investigation of non-equilibrium resonator states in the quantum domain. We find our model emerges naturally in disordered elastic media such as glasses, and is an additional, expected effect in systems with anomalous specific heat and 1/f noise at low temperatures due to two-level systems that fluctuate.

description: The objective of this study was to compare the pre-hospital health care process, clinical characteristics at admission and survival of patients with a digestive tract cancer first admitted to hospital either electively or via the emergency department. The study involved cross-sectional analysis of information elicited through personal interview and prospective follow-up. The setting was a 450-bed public teaching hospital primarily serving a low-income area of Barcelona, Catalonia, Spain. Two hundred and forty-eight symptomatic patients were studied, who had cancer of the oesophagus (n = 31), stomach (n = 70), colon (n = 82) and rectum (n = 65). The main outcome measures were stage, type and intention of treatment and time elapsed from admission to surgery; the relative risk of death was calculated using Cox's regression. There were 161 (65%) patients admitted via the emergency department and 87 (35%) electively. The type of physician seen at the first pre-hospital visit had more often been a general practitioner in the emergency than in the elective group (89% vs 75%, P < 0.01). Emergency patients had seen a lower number of physicians from symptom onset until admission, but two-thirds had made repeated visits to a primary care physician. Emergency patients were less likely to have a localized tumour and a diagnosis of cancer at admission, and surgery as the initial treatment. Median survival was 30 months for elective patients and 8 months for emergency patients (P < 0.001), and the relative risk of death (RR) was 1.83 (95% confidence interval, CI, 1.32-2.54). After adjustment for strong prognostic factors, emergency patients continued to experience a significant excess risk (RR = 1.58; CI 1.10-2.27). In conclusion, in digestive tract cancers, admission to hospital via the emergency department is a clinically important marker of a poorer prognosis. Emergency departments can only partly counterbalance deficiencies in the effectiveness of and integration among the different levels of the health system.

description: The G1 cell cycle checkpoint regulates entry into S phase for normal cells. Components of the G1 checkpoint, including retinoblastoma (Rb) protein, cyclin D1 and p16INK4a, are commonly altered in human malignancies, abrogating cell cycle control. Using immunohistochemistry, we examined 79 invasive transitional cell carcinomas of the urinary bladder treated by cystectomy, for loss of Rb or p16INK4a protein and for cyclin D1 overexpression. As p53 is also involved in cell cycle control, its expression was studied as well. Rb protein loss occurred in 23/79 cases (29%); it was inversely correlated with loss of p16INK4a, which occurred in 15/79 cases (19%). One biphenotypic case, with Rb+p16– and Rb-p16+ areas, was identified as well. Cyclin D1 was overexpressed in 21/79 carcinomas (27%), all of which retained Rb protein. Fifty of 79 tumours (63%) showed aberrant accumulation of p53 protein; p53 staining did not correlate with Rb, p16INK4a, or cyclin D1 status. Overall, 70% of bladder carcinomas showed abnormalities in one or more of the intrinsic proteins of the G1 checkpoint (Rb, p16INK4a and cyclin D1). Only 15% of all bladder carcinomas (12/79) showed a normal phenotype for all four proteins. In a multivariate survival analysis, cyclin D1 overexpression was linked to less aggressive disease and relatively favourable outcome. In our series, Rb, p16INK4a and p53 status did not reach statistical significance as prognostic factors. In conclusion, G1 restriction point defects can be identified in the majority of bladder carcinomas. Our findings support the hypothesis that cyclin D1 and p16INK4a can cooperate to dysregulate the cell cycle, but that loss of Rb protein abolishes the G1 checkpoint completely, removing any selective advantage for cells that alter additional cell cycle proteins. © 1999 Cancer Research Campaign

description: Pimonidazole is finding increasing use in histochemical analyses of hypoxia in tumours. Whether it can identify every hypoxic cell in a tumour, and whether the usual subjective criteria used to define ‘positive’ cells are optimal, are less certain. Therefore, our aim was to develop an objective flow cytometry procedure for quantifying pimonidazole binding in tumours, and to validate this method by using a more direct indicator of radiobiologic hypoxia, the comet assay. SCCVII tumours in C3H mice were analysed for pimonidazole binding using flow cytometry and an iterative curve-fitting procedure, and the results were compared to the comet assay for the same cell suspensions. On average, cells defined as anoxic by flow analysis (n = 43 tumours) bound 10.8 ± 0.95 times more antibody than aerobic cells. In samples containing known mixtures of aerobic and anoxic cells, hypoxic fractions as low as 0.5% could easily be detected. To assess the flow cytometry assay under a wider range of tumour oxygen contents, mice were injected with hydralazine to reduce tumour blood flow, or allowed to breathe various gas mixtures during the 90 min exposure to pimonidazole. Hypoxic fraction estimated by the pimonidazole binding method agreed well with the hypoxic fraction measured using the comet assay in SCCVII tumours (r2 = 0.87, slope = 0.98), with similar results in human U87 glioma cells and SiHa cervical carcinoma xenografts. We therefore conclude that this objective analysis of pimonidazole labelling by flow cytometry gives a convenient and accurate estimate of radiobiological hypoxia. Preliminary analyses of biopsies from 3 patients given 0.5 g m–2 pimonidazole also suggest the suitability of this approach for human tumours. © 2000 Cancer Research Campaign http://www.bjcancer.com

description: Este proyecto tiene por objeto mostrar que la tendencia a la eliminación de la filosofía como asignatura del plan curricular de la educación media en Colombia se ha convertido en una política de Estado en el marco de la mercantilización de la educación, requerida por el modelo económico neoliberal. Este diagnóstico crítico, aunque básico del fenómeno, también reconocido como crisis de la educación, enarbola a la filosofía en la educación como condición fundamental para el desarrollo sustentable de las sociedades modernas. Para mostrarlo, se parte del esbozo de una revisión histórica del marco normativo y político que ha definido, en el contexto nacional, el papel asignado a la filosofía en los currículos y se analizan algunos planteamientos sobre el verdadero objeto del componente de la filosofía en el diseño curricular actual. Luego se perfila el carácter de la filosofía como una actividad a la que la pluralidad humana debe tener derecho; por último, se busca establecer la relación entre la paulatina relegación o reducción de su aprendizaje, en términos de conciencia o lectura crítica, y la crisis de libertad que atraviesa el país.
