Pneumoperitoneum, Pneumoretroperitoneum, Pneumomediastinum And Extensive Subcutaneous Emphysema In A Patient With Ulcerative Colitis: A Case Report., Usman T Siddiqui, Hira Shahzad, Asad Raja

Department of Surgery Docs

Abstract

INTRODUCTION:

Pneumo-mediastinum and subcutaneous emphysema are rare presentations of lower gastrointestinal tract perforation.

PRESENTATION OF CASE:

We are presenting the case of a middle aged man diagnosed with UC who presented with dyspnea and subcutaneous emphysema, attributed to multiple perforations including the stomach and colon.

CASE DISCUSSION:

Patients with ulcerative colitis (UC) are at an increased risk of perforations due to friability of colonic mucosa given the chronic inflammation and relapsing flares. Chronic use of steroids further predisposes to stress ulcers. These pathologies sometimes coexist and identification of each is crucial for the appropriate treatment plan.

CONCLUSION:

We Built This City: Public Participation In Land Use Decisions In Singapore, Jack Tsen-Ta Lee

Research Collection Yong Pung How School Of Law

This article considers the extent to which the legal framework for making land use decisions in Singapore allows for public participation. It examines the issue from two angles: the creation and preservation of the built environment, and the transient use of public space. The first angle is discussed primarily from a heritage law viewpoint, focusing on planning law, compulsory acquisition law, and the legal regime for creating national monuments. As for the second angle, the article looks at how the use of common spaces for assemblies and processions is regulated. The foregoing are examined in the context of Edward Soja’s …

A Critical Assessment Of The Role Of The Venice Commission In Processes Of Domestic Constitutional Reform, Maartje De Visser

Research Collection Yong Pung How School Of Law

On January 26, 2014, an overwhelming majority of the National Constituent Assembly of Tunisia approved the country's new constitution. Drafted in the aftermath of the Tunisian revolution, the constitution received considerable international critical acclaim, regarding the manner in which the text had been drafted and adopted as well as its content, notably the entrenchment of a host of fundamental rights and liberties. Comparisons have inevitably been drawn with Egypt's new constitution and those of other Arab nations, with the Tunisian text hailed as one of the most progressive in the region, providing the foundations for a modern and credible democracy. …

Reputation And Defamatory Meaning On The Internet: Communications, Contexts And Communities, Gary Kok Yew Chan

Research Collection Yong Pung How School Of Law

The determination of the appropriate scope of protection of reputation in the tort of defamation is crucially dependent on the construction of defamatory meaning. With the continuing rise of Internet publications, it is important to assess the impact of the various modes of Internet communications such as Internet websites, hyperlinking, blogs, emails, Twitter, Facebook and other forms of social media on defamatory meaning. Such defamatory meaning is being constructed based on the unique contexts and social expectations that have been generated by the various modes of Internet communications. The potential impact on defamatory meaning can also be assessed from the …

Accessory Liability In Tort And Equity, Pey Woan Lee

Research Collection Yong Pung How School Of Law

Unlike the position in criminal law, there does not currently exist a general doctrine of accessory liability in civil law. Thus, a person may be liable as an accessory in equity for dishonestly assisting with a breach of trust, but there is no tort for dishonest assistance. Rather, one who participates in another's tort will only be liable if he is a joint tortfeasor acting pursuant to a common design with the primary tortfeasor. This article examines the reasons for this divergence and evaluates the case for their assimilation. It observes that, contrary to common perception, the scope of participatory …

Genome Rearrangements Can Make And Break Small Rna Genes, Rahul Raghavan, Fenil R. Kacharia, Jess A. Millar, Christine Demko Sislak, Howard Ochman

Biology Faculty Publications and Presentations

Small RNAs (sRNAs) are short, transcribed regulatory elements that are typically encoded in the intergenic regions (IGRs) of bacterial genomes. Several sRNAs, first recognized in Escherichia coli, are conserved among enteric bacteria, but because of the regulatory roles of sRNAs, differences in sRNA repertoires might be responsible for features that differentiate closely related species. We scanned the E. coli MG1655 and Salmonella enterica Typhimurium genomes for nonsyntenic IGRs as a potential source of uncharacterized, species-specific sRNAs and found that genome rearrangements have reconfigured several IGRs causing the disruption and formation of sRNAs. Within an IGR that is present in …

Are Large Dogs Smarter Than Small Dogs? Investigating Within Species Differences In Large And Small Dogs: Spatial Memory, Megan S. Broadway

Master's Theses

The study of canine cognition can be useful in understanding the ontology and selective pressures that affect the development of cognitive abilities. Dogs have undergone intensive artificial selection yielding distinctive breeds which differ both phenotypically and behaviorally. Breed based cognitive differences have not been found but some studies suggest there may be differences in broader categories such as working disposition and sex. The influence of size on canine cognition has not been thoroughly addressed despite the fact that large dogs are often perceived to be ‘smarter’ than small dogs. This preconception has only recently been addressed and supported in one …

Same-Sex Socio-Sexual Interactions Among A Group Of Captive Bottlenose Dolphins (Tursiops Truncatus), Natalia Botero Acosta

Master's Theses

Bottlenose dolphins (Tursiops truncatus) frequently engage in non-reproductive sexual behavior, including homosexual encounters. In order to better understand the nature and function of these interactions, a longitudinal study of the patterns of association and the dynamics of initiator/recipient role exchange was conducted. Underwater video footage of a colony of bottlenose dolphins housed at the Roatan Institute for Marine Sciences (RIMS), collected between March of 2010 and May of 2013, was analyzed. Associations occurring during homosexual interactions were transitory for most individuals. Nonetheless, subsequent analyses allowed the rejection of the null hypothesis of random association, suggesting the existence of …

Maternal Effects And Offspring Behavior: Potential Contributors To The Lack Of Recruitment In Mississippi Gopher Tortoises (Gopherus Polyphemus), Aaron L. Holbrook

Master's Theses

Federally threatened in Mississippi, gopher tortoise (Gopherus polyphemus) populations within the state have strongly variable recruitment and are generally in decline. Hatching success is significantly lower in Mississippi than in any other part of the species’ range , and most hatchlings die within the first year. There are few refuges where survival and hatching success is high. Here I compare two populations that differ in recruitment and offspring survival for differences in corticosterone. Corticosterone is a hormone that influences both energy availability and is released in elevated levels during stressful events, like living in poor quality habitat. Prolonged corticosterone elevation …

Burial Chronological Sequencing Of The Colonial Maya Cemetery At Tipu, Belize Using Fluoride Ion Analysis, Nicole Musselwhite

Master's Theses

This thesis ascertains the sequence of burials using fluoride ion electrode analysis at the colonial cemetery at Tipu, Belize in order to explore demographic and other cultural effects associated with European contact. The cemetery at Tipu in west central Belize, dating from within the first century of Spanish contact, has provided one of the largest and best preserved Maya skeletal series, with over 500 burials recovered. While this series has undergone vast amounts of analysis, there has yet been an analysis conducted to view how patterns changed over time. This is of interest given the rapid culture change associated with …

The Impact Of Service-Learning Classes On Teacher Education Candidates’ Views Of Diversity, Jason D. Fruth, Anna F. Lyon, Alan Avila-John

eJournal of Public Affairs

This study examined the impact that a service-learning component in a disability and culture course had on the views of diversity for teacher candidates at a Midwestern university. A group of 96 students took either a treatment course with an additional service-learning component or a control course without the additional component. Diversity scales and qualitative accounts were used as preand post-measures to determine the impact of the students’ service-learning experience. The study found substantial differences in the changes in views on diversity between the two groups, especially in relation to views on gender opportunity and teacher expectations.

Moss In The Classroom: A Tiny But Mighty Tool For Teaching Biology, Erin E. Shortlidge, James R. Hashimoto

Biology Faculty Publications and Presentations

Here we present a mechanism to infuse ecology into the classroom using a broadly adaptable system. We developed a novel moss-based project that introduces research-based experiences for middle school students, and can be modified for integration into K-16 classrooms. The project is ecologically relevant, facilliating opportunities for students to experience intimate interactions with ecosystem subtleties by asking their own questions. We describe and suggest how students can develop, build, test, and assess microcosm experiments of their own design, learning the process of science by “doing science.” Details on project execution, representative examples of distinctive research-question-based projects are presented. We aim …

Evaluation Of Alternative Intersections And Interchanges: Volume I—Roundabout Capacity And Rollover Analysis For Heavy Vehicles, Andrew P. Tarko, Mario Romero, Thomas Hall, Shaikh Ahmad Matin, Cristhian Lizarazo

JTRP Technical Reports

There is a recent trend of building roundabouts on high-speed roads, often with the considerable presence of heavy vehicles. With the increased presence of trucks on roundabouts, the issue of overturning has become a concern. Although some geometric, vehicle, and loading factors have been connected to rollover, the safety performance of roundabouts built on high-speed roads is not well understood due to their relative novelty. In addition, other concerns related to geometry, driver behavior, and environmental considerations may exist at roundabouts. This study examined roundabout circulatory superelevation, aggressive driver behavior, roundabout readability, and nighttime conditions in the context of heavy …

Transcriptomics In Type 2 Diabetes: Bridging The Gap Between Genotype And Phenotype, Christopher Jenkinson, Harald H. H. Goring, Rector Arya, John Blangero, Ravindranath Duggirala, Ralph A. Defronzo

School of Medicine Publications

Type 2 diabetes (T2D) is a common,multifactorial disease that is influenced by genetic and environmental factors and their interactions. However, common variants identified by genome wide association studies (GWAS) explain only about 10% of the total trait variance for T2D and less than 5% of the variance for obesity, indicating that a large proportion of heritability is still unexplained. The transcriptomic approach described here uses quantitative gene expression and disease-related physiological data (deep phenotyping) to measure the direct correlation between the expression of specific genes and physiological traits. Transcriptomic analysis bridges the gulf between GWAS and physiological studies. Recent GWAS …

Development And Implementation Of Hay Yield Monitoring Technology, Henry Ramsey

All Theses

Three independent technologies related to hay yield monitoring were developed and studied. One technology involved comparison of infrared and ultrasonic sensors on a self-propelled forage harvester. Sensor response related to grass height and was used to estimate yield. Plots that were harvested ranged from 20-40 ft. in length while a bin mounted on the back of the mower collected the crop for weighing and sampling. The infrared sensors data demonstrated accuracies across plots between 5.9% and 9.5% error. The infrared sensors quickly deteriorated and eventually proved to be useless for data acquisition. As for the ultrasonic sensors, they demonstrated similar …

Design Of A Meta-Material With Targeted Nonlinear Deformation Response, Zachary Satterfield

All Theses

The M1 Abrams tank contains track pads consist of a high density rubber. This rubber fails prematurely due to heat buildup caused by the hysteretic nature of elastomers. It is therefore desired to replace this elastomer by a meta-material that has equivalent nonlinear deformation characteristics without this primary failure mode. A meta-material is an artificial material in the form of a periodic structure that exhibits behavior that differs from its constitutive material. After a thorough literature review, topology optimization was found as the only method used to design meta-materials. Further investigation determined topology optimization as an infeasible method to design …

Co-Design Of Dynamic Real-Time Scheduling And Cooperative Control For Human-Agent Collaboration Systems Based On Mutual Trust, Xiaotian Wang

All Theses

Mutual trust is a key factor in human-human collaboration. Inspired by this social interaction, we analyze human-agent mutual trust in the collaboration of one human and (semi)autonomous multi-agent systems. In the thesis, we derive time-series human-agent mutual trust models based on results from human factors engineering. To avoid both over- trust and under-trust, we set up dynamic timing models for the multi-agent scheduling problem and develop necessary and sufficient conditions to test the schedulability of the human multi-agent collaborative task. Furthermore, we extend the collaboration between one human and multiple agents into the collaboration between multi-human network and swarm-based agents …

Influence Of Exurban Neighborhoods On Riparian Vegetation And Stream Salamanders In The Southern Appalachian Mountains, Nathaniel Weaver

All Theses

The southern Appalachian Mountains have experienced large population growth and a change in land use in the past 30 years. The majority of development has been low density, suburban land, known as exurban development. Lotic Systems and riparian areas are severely degraded by conversion from urban to rural land uses. The long-term effects of exurbanization on riparian vegetative communities and stream salamanders in the southern Appalachian Mountains are not well known. We sought to determine if vegetative community composition and structure change with time since neighborhood development or with the amount of impervious surface within the watershed. In order to …
