Ac-Sdkp Decreases Mortality And Cardiac Rupture After Acute Myocardial Infarction, Pablo Nakagawa, Cesar A. Romero, Xu Jiang, Martin D'Ambrosio, Ginette Bordcoch, Edward L. Peterson, Pamela Harding, Xiao-Ping Yang, Oscar A. Carretero Jan 2018

Ac-Sdkp Decreases Mortality And Cardiac Rupture After Acute Myocardial Infarction, Pablo Nakagawa, Cesar A. Romero, Xu Jiang, Martin D'Ambrosio, Ginette Bordcoch, Edward L. Peterson, Pamela Harding, Xiao-Ping Yang, Oscar A. Carretero

Hypertension and Vascular Research Articles

The natural peptide N-Acetyl-Seryl-Aspartyl-Lysyl-Proline (Ac-SDKP) decreases inflammation in chronic diseases such as hypertension and heart failure. However, Ac-SDKP effects on acute inflammatory responses during myocardial infarction (MI) are unknown. During the first 72 hours post-MI, neutrophils, M1 macrophages (pro-inflammatory), and M2 macrophages (pro-resolution) and release of myeloperoxidase (MPO) and matrix metalloproteinases (MMP) are involved in cardiac rupture. We hypothesized that in the acute stage of MI, Ac-SDKP decreases the incidence of cardiac rupture and mortality by preventing immune cell infiltration as well as by decreasing MPO and MMP expression. MI was induced by ligating the left descending coronary artery in …

An Experimental Protocol To Model Recovery Of Anaerobic Work Capacity, Vijay Sarthy M. Sreedhara, Gregory M. Mocko, Randolph Hutchison Jan 2018

An Experimental Protocol To Model Recovery Of Anaerobic Work Capacity, Vijay Sarthy M. Sreedhara, Gregory M. Mocko, Randolph Hutchison

Health Sciences Publications

Models of fatigue are based on physiological parameters such as Critical Power (CP) and Anaerobic Work Capacity (AWC). CP is a theoretical threshold value that a human can generate for an indefinite amount of time and AWC represents a finite expendable amount of anaerobic energy at intensities above CP. There is an increasing interest in developing mathematical models of energy expenditure and recovery for athletic training and human performance. The objective of this research is to propose and validate a model for recovery of AWC during a post exertion recovery interval of cycling. A cycling …

Modeling The Expenditure And Recovery Of Anaerobic Work Capacity In Cycling, Phoebe Bickford, Vijay Sarthy M. Sreedhara, Gregory M. Mocko, Ardalan Vahidi, Randolph Hutchison Jan 2018

Modeling The Expenditure And Recovery Of Anaerobic Work Capacity In Cycling, Phoebe Bickford, Vijay Sarthy M. Sreedhara, Gregory M. Mocko, Ardalan Vahidi, Randolph Hutchison

Health Sciences Publications

The objective of this research is to model the expenditure and recovery of Anaerobic Work Capacity (AWC) as related to Critical Power (CP) during cycling. CP is a theoretical value at which a human can operate indefinitely and AWC is the energy that can be expended above CP. There are several models to predict AWC-depletion, however, only a few to model AWC recovery. A cycling study was conducted with nine recreationally active subjects. CP and AWC were determined by a 3-min all-out test. The subjects performed interval tests at three recovery intervals (15 s, 30 s, …

Development Of Simple Devices For Point-Of-Care Screening Of Bacterial Infection And Inflammatory Markers, Julaluk Noiphung Jan 2018

Development Of Simple Devices For Point-Of-Care Screening Of Bacterial Infection And Inflammatory Markers, Julaluk Noiphung

Chulalongkorn University Theses and Dissertations (Chula ETD)

A paper-based analytical devices (PADs) provides a great benefit in medical diagnostics, especially in the developing world. The first part of this dissertation describes the effect of sample viscosity on PADs for the measurement of pH and nitrite concentration in human saliva. Preliminary study found that viscosity had a significant effect on the calibration curve of nitrite and a consistent curve could be generated after added washing buffer. Nitrite measurement in artificial saliva with viscosity 1.87-5.10 mPa-s was tested on the proposed device and also showed a good correlation with the standard spectrophotometry method (p=0.8484, paired sample t-test, n=20). Moreover, …

Why Do We Want To Think Humans Are Different?, Colin A. Chapman, Michael A. Huffman Jan 2018

Why Do We Want To Think Humans Are Different?, Colin A. Chapman, Michael A. Huffman

Animal Sentience

One harmful consequence of creating categories where one group is unique and superior to others is that it justifies committing negative, often atrocious, acts on the members of the inferior group. Correcting divisive human categorizations (racial superiority, gender superiority) has bettered society. Scholars have often claimed that humans are unique and superior to nonhuman animals. These claims need to be reevaluated. Many have already been refuted. Animals have been shown to outperform humans in many tasks, including cognitive ones. Here we raise the question: Has the false sense of superiority been used to justify human cruelty to animals?

Human And Nonhuman Animals: Equals In Uniqueness, Uta Maria Juergens Jan 2018

Human And Nonhuman Animals: Equals In Uniqueness, Uta Maria Juergens

Animal Sentience

Chapman & Huffman attack the idea that humans are unique and therefore superior to nonhuman beings. They call on humankind to use their “intellect to change [their] actions.” I am in full accord with their line of thought, which differentiates uniqueness from superiority and enjoins humans to take responsible action. I suggest, however, that humans are unique with regard to cognitive fluidity. The same conclusions can be reached via another argument based on human uniqueness.

Good News: Humans Are Neither Distinct Nor Superior, Anne Benvenuti Jan 2018

Good News: Humans Are Neither Distinct Nor Superior, Anne Benvenuti

Animal Sentience

Chapman & Huffman suggest that to correct our thinking about the supposed superiority of humans over other animals, we must train our reasoned investigation upon ourselves. Their thesis may usefully be viewed from within the general findings of the cognitive revolution in science, particularly findings that speak to the limits of rationality in everyday thought of humans. That we have failed — throughout a long history of scientific and philosophical thought — to ask fundamental questions about animal cognition and emotion is rooted in the fact that much of our thinking, feeling, and behaving is beyond our own immediate grasp. …

Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson Jan 2018

Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson

Animal Sentience

Chapman & Huffman (2018) argue that we should not consider humans as unique or superior to other animals when we have the chance to explore the diversity of the traits of other species. This is a valid and progressive point in our approach to research, but I suggest that an anthropocentric approach can have animal welfare benefits when it helps us perceive other species – especially distantly related ones such as crustaceans – in a human light.

Why Humans Are Different, Tara Fox Hall Jan 2018

Why Humans Are Different, Tara Fox Hall

Animal Sentience

A central human problem is our inference from the fact that we are the world’s most intelligent species to the alleged fact that we are superior. This inference is not mandatory. Successfully combating this inference may require the threat of a large-scale catastrophe to our species.

How To Foster Respect For Animals? Superiority, Dissimilarity, And Prejudice, Matteo Colombo Jan 2018

How To Foster Respect For Animals? Superiority, Dissimilarity, And Prejudice, Matteo Colombo

Animal Sentience

Chapman & Huffman (C & H) might be taken to argue as follows: Humans may treat animals however they want only if humans are superior to animals. But humans are not superior to animals. Therefore, humans may not treat animals however they want. Whatever its merit, this is not C & H’s actual argument. Their point, instead, is that humans often mistreat animals because they tend to perceive them as inferior. A remedy for animal mistreatment would then be acknowledging the deep similarities between us and animals. But is C & H’s suggested remedy likely to be effective to foster …

Insulting Words: "They Are Animals!", Carolyn A. Ristau Jan 2018

Insulting Words: "They Are Animals!", Carolyn A. Ristau

Animal Sentience

As Chapman & Huffman state, creating divisive human categories has rationalized atrocities committed against the “other.” Labeling neighboring warring villagers as “animals” is considered a despicable insult. Yet contemporary scientific views of many animals grant them thinking and conscious faculties, and the capacity for impressive achievements, many unattainable by humans. Robots, too, can accomplish many similar feats. But the essential reason we must protect animals is not because of their admirable abilities, but their capacity for consciousness, for suffering. Robots are not conscious. Participants in the human-animal debate should not complain about changing criteria for determining human uniqueness. New and …

Human-Like Behavior And Cognition: Not A Good Starting Point, Magnus Helgheim Blystad Jan 2018

Human-Like Behavior And Cognition: Not A Good Starting Point, Magnus Helgheim Blystad

Animal Sentience

Chapman & Huffman make use of observations and studies that show how humans may not be as unique in our behaviour and cognition as previously thought. I wholeheartedly agree that our uniqueness might be small and that if it exists, it should not give our species any right to act cruelly towards other animals. However, this kind of logic can be problematic. I present a few of the issues in this commentary.

Two Fallacies In Comparisons Between Humans And Non-Humans, Don Ross Jan 2018

Two Fallacies In Comparisons Between Humans And Non-Humans, Don Ross

Animal Sentience

The hypothesis that humans are superior to non-humans by virtue of higher cognitive powers is often supported by two recurrent fallacies: (1) that any competence shown by humans but not by our closest living relatives (apes) must be unique to humans; and (2) that grades of intelligence can be inferred from behavior without regard to motivational structures.

What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy Jan 2018

What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy

Animal Sentience

We agree with Chapman & Huffman that human capacities are often assumed to be unique — or attempts are made to demonstrate uniqueness scientifically — in order to justify the exploitation of animals and ecosystems. To extend the argument that human exceptionalism is against our interests, we recommend adopting the One Welfare framework, according to which animal welfare, environmental sustainability and human wellbeing are inseparably linked. Let us distinguish ourselves from other animals by resisting our short- and mid-term Darwinian inclinations, consuming less, reproducing less, and striving for a much longer-term biological fitness for us all.

Fine-Scale Hydrodynamic Metrics Underlying Predator Occupancy Patterns In Tidal Stream Environments, Lilian Lieber, Smith Wam Nimmo, James J. Waggitt, Louise Kregting Jan 2018

Fine-Scale Hydrodynamic Metrics Underlying Predator Occupancy Patterns In Tidal Stream Environments, Lilian Lieber, Smith Wam Nimmo, James J. Waggitt, Louise Kregting

School of Biological and Marine Sciences

Whilst the development of the tidal stream industry will help meet marine renewable energy (MRE) targets, the potential impacts on mobile marine predators using these highly dynamic environments need consideration. Environmental impact assessments (EIAs) required for potential MRE sites generally involve site-specific animal density estimates obtained from lengthy and costly surveys. Recent studies indicate that whilst large-scale tidal forcing is predictable, local hydrodynamics are variable and often result in spatio-temporal patchiness of marine predators. Therefore, understanding how fine-scale hydrodynamics influence animal distribution patterns could inform the placing of devices to reduce collision and displacement risks. Quantifying distributions requires animal at-sea …

School of Biological and Marine Sciences

Chemolithoautotrophic bacteria from the genera Hydrogenovibrio, Thiomicrorhabdus, and Thiomicrospira are common, sometimes dominant, isolates from sulfidic habitats including hydrothermal vents, soda and salt lakes, and marine sediments. Their genome sequences confirm their membership in a deeply branching clade of the Gammaproteobacteria. Several adaptations to heterogeneous habitats are apparent. Their genomes include large numbers of genes for sensing and responding to their environment (EAL- and GGDEF-domain proteins, and methyl-accepting chemotaxis proteins) despite their small sizes (2.1 - 3.1 Mbp). An array of sulfur-oxidizing complexes are encoded, likely to facilitate these organisms' use of multiple forms of reduced sulfur as electron donors. …

Enhancing Security Behaviour By Supporting The User, Sm Furnell, W Khern-Am-Nuai, R Esmael, W Yang, N Li Jan 2018

Enhancing Security Behaviour By Supporting The User, Sm Furnell, W Khern-Am-Nuai, R Esmael, W Yang, N Li

School of Engineering, Computing and Mathematics

Although the role of users in maintaining security is regularly emphasized, this is often not matched by an accompanying level of support. Indeed, users are frequently given insufficient guidance to enable effective security choices and decisions, which can lead to perceived bad behaviour as a consequence. This paper discusses the forms of support that are possible, and seeks to investigate the effect of doing so in practice. Specifically, it presents findings from two experimental studies that investigate how variations in password meter usage and feedback can positively affect the resulting password choices. The first experiment examines the difference between passwords …

Towards Bayesian-Based Trust Management For Insider Attacks In Healthcare Software-Defined Networks, W Meng, K-Kr Choo, S Furnell, Av Vasilakos, Cw Probst

School of Engineering, Computing and Mathematics

The medical industry is increasingly digitalized and Internet-connected (e.g., Internet of Medical Things), and when deployed in an Internet of Medical Things environment, software-defined networks (SDNs) allow the decoupling of network control from the data plane. There is no debate among security experts that the security of Internet-enabled medical devices is crucial, and an ongoing threat vector is insider attacks. In this paper, we focus on the identification of insider attacks in healthcare SDNs. Specifically, we survey stakeholders from 12 healthcare organizations (i.e., two hospitals and two clinics in Hong Kong, two hospitals and two clinics in Singapore, and two …

“Read And Be Convinced”: The Image Of The Nonpartisan League In Its Creative Production, The Early Histories, And Wider Popular Culture, John Hest Jan 2018

“Read And Be Convinced”: The Image Of The Nonpartisan League In Its Creative Production, The Early Histories, And Wider Popular Culture, John Hest

History, Philosophy, and Religious Studies

In this thesis, I examine the image of the Nonpartisan League in several different contexts, arguing that the League carefully crafted their advocative political image and their opponents painted them as disloyal socialists. The Nonpartisan League was an agrarian radical political movement beginning in North Dakota in 1915, and both its proponents and opponents created powerful images of it. I first examine the creative output of two Leaguers, the poet Florence Borner and the cartoonist John Miller Baer. I then transition to four competing histories of the Nonpartisan League, published from 1920-21, by Herbert Gaston, Charles Edward Russell, William Langer, …

Electrically Conductive Polymers And Their Use As Novel Pigments In Advanced Coatings, Joseph Robert Byrom Jan 2018

Electrically Conductive Polymers And Their Use As Novel Pigments In Advanced Coatings, Joseph Robert Byrom

Coatings and Polymeric Materials

With the push to more environmentally friendly materials to solve some of the biggest challenges in the coatings industry, electrically conductive polymers (ECPs) are seen as a flexible solution due to their unique properties. ECPs are seen as an attractive substitute to the current metallic materials used in applications such as printable electronics, anti-static protection, and corrosion mitigation. Polypyrrole (PPy) is seen as a popular class of ECPs due to its inherent high electrical conductivity, resistance to environmental degradation, and ease of synthesis. The first part of this work was to study the ability of polypyrrole to be synthesized through …
