Unlikely Partners: Tort Law As A Tool For Trans Activism, Courtney Sirwatka
Unlikely Partners: Tort Law As A Tool For Trans Activism, Courtney Sirwatka
Cardozo Journal of Equal Rights & Social Justice
The note argues that tort law reform and trans activism can mutually benefit each other by addressing systemic discrimination and advancing equality for trans individuals. It critiques the legal system for perpetuating discrimination through its emphasis on physical injury over emotional or sexual harm and its refusal to validate trans identities. The analysis proposes that recognizing sexual autonomy and reproduction as protected interests in tort law, along with legal education reforms, could legitimize trans narratives and lead to meaningful change.

Melungeon Portraits: Lived Experience And Identity, Tamara L. Stachowicz
Melungeon Portraits: Lived Experience And Identity, Tamara L. Stachowicz
Antioch University Dissertations & Theses
The desire to claim an ethnicity may be in response to an institutional and systemic political movement towards multiculturalism where ethnic difference is something to be recognized and celebrated (Jimenez, 2010; Tatum, 1997). Those who were a member of a dominant or advantaged group took that element of their identity for granted (Tatum, 1997). Identity work has included reflections and congruence between how individuals see themselves and how they perceive others to see them, including Optimal Distinctiveness Theory where one determines the optimal amount of individual distinctiveness needed to feel a healthy group and personal identity (Brewer, 2012). When most …

Histology And Ultrastructure Of Transitional Changes In Skin Morphology In The Juvenile And Adult Four-Striped Mouse (Rhabdomys Pumilio), Eranée Stewart, Moyosore Salihu Ajao, Amadi O. Ihunwo
Brain and Mind Institute
The four-striped mouse has a grey to brown coloured coat with four characteristic dark stripes interspersed with three lighter stripes running along its back. The histological differences in the skin of the juvenile and adult mouse were investigated by Haematoxylin and Eosin and Masson Trichrome staining, while melanocytes in the skin were studied through melanin-specific Ferro-ferricyanide staining. The ultrastructure of the juvenile skin, hair follicles, and melanocytes was also explored. In both the juvenile and adult four-striped mouse, pigment-containing cells were observed in the dermis and were homogeneously dispersed throughout this layer. Apart from these cells, the histology of the …

Reconstruction Amendments says about the nature of American citizenship. The essay is organized as follows. Part I of the essay explores citizenship and membership by discussing belonging-based citizenship and rights-based citizenship. Part II describes how American and African American citizenship were constructed prior to the passage of the Reconstruction Amendments. Part III notes a few cases to explain how the Reconstruction Amendment's jurisprudence has developed in the wake of Dred Scott v. Sandford' and possibly led to a tilt toward a rights-based citizenship rather than a somewhat more robust belonging-based citizenship.

Horseshoe Crab Eggs: A Rare Resource For Predators In Long Island Sound, Mark Beekey, Jennifer Mattei, Barbara J. Pierce
Horseshoe Crab Eggs: A Rare Resource For Predators In Long Island Sound, Mark Beekey, Jennifer Mattei, Barbara J. Pierce
Biology Faculty Publications
In Delaware Bay, the spawning of several million horseshoe crabs (Limulus polyphemus) coincides with the arrival of migratory shorebirds that feed on their eggs. High horseshoe crab spawning densities and resulting high egg densities drive egg availability and predation rates. At high spawning densities, female horseshoe crabs perturb previously deposited clutches causing eggs to rise to the sediment surface (surface egg densities average 100,000 eggs m− 2). At the surface (0–5 cm), the eggs are quickly depleted by shorebirds and other predators. This interaction between egg density and egg predation has not been explicitly explored on …
A Historical Geography Of Sand Island 1870–1944, Lucas P. Johnson
A Historical Geography Of Sand Island 1870–1944, Lucas P. Johnson
Department of Geography: Dissertations, Theses, and Student Research
This thesis examines the settlement of Sand Island, one of two permanent colonies included within Lake Superior’s Apostle Islands archipelago. Following the introduction and literature review, a summary of Sand Island’s geology, climate and biological features is presented, serving to construct a baseline upon which to build a discussion of the island’s communal life. This foundation gives context to the seventy-four year struggle faced by the predominantly Norwegian immigrants adapting to that environment. It also serves to assist future scholars in studying wilderness recovery after what today is nearly an eighty year absence of the farmer’s plow. Chapter Four includes …

Abstract
Background
Previous whole-genome shotgun bisulfite sequencing experiments showed that DNA cytosine methylation in the honey bee (Apis mellifera) is almost exclusively at CG dinucleotides in exons. However, the most commonly used method, bisulfite sequencing, cannot distinguish 5-methylcytosine from 5-hydroxymethylcytosine, an oxidized form of 5-methylcytosine that is catalyzed by the TET family of dioxygenases. Furthermore, some analysis software programs under-represent non-CG DNA methylation and hydryoxymethylation for a variety of reasons. Therefore, we used an unbiased analysis of bisulfite sequencing data combined with molecular and bioinformatics approaches to distinguish 5-methylcytosine from 5-hydroxymethylcytosine. By doing this, we have performed the first whole …

Abstract
Introduction
The association of breast cancer patients’ mortality with estrogen receptor (ER) status (ER + versus ER-) has been well studied. However, little attention has been paid to the relationship between the quantitative measures of ER expression and mortality.
Methods
We evaluated the association between semi-quantitative, immunohistochemical staining of ER in formalin-fixed paraffin-embedded breast carcinomas and breast cancer-specific mortality risk in an observational cohort of invasive breast cancer in 681 white women and 523 black women ages 35-64 years at first diagnosis of invasive breast cancer, who were followed for a median of 10 years. The quantitative measures of …

Abstract
Background
Residence near municipal solid waste incinerators, a major historical source of dioxin emissions, has been associated with increased risk of non-Hodgkin lymphoma (NHL) in European studies. The aim of our study was to evaluate residence near industrial combustion facilities and estimates of dioxin emissions in relation to NHL risk in the United States.
Methods
We conducted a population-based case–control study of NHL (1998–2000) in four National Cancer Institute-Surveillance Epidemiology and End Results centers (Detroit, Iowa, Los Angeles, Seattle). Residential histories 15 years before diagnosis (similar date for controls) were linked to an Environmental Protection Agency database of dioxin-emitting …

Biochemical, Structural, And Drug Design Studies Of Multi-Drug Resistant Hiv-1 Therapeutic Targets, Tamaria Grace Dewdney
Wayne State University Dissertations
Protein point mutations acquired as a mechanism of survival against therapeutics cause structural changes that effect protein function and inhibitor binding. This work investigates the structural mechanisms that lead to multi-drug resistance to HIV-1 protease and integrase inhibitors.
Proper proteolytic processing of the HIV-1 Gag/Pol polyprotein is required for HIV infection and viral replication. This feature has made HIV-1 protease an attractive target for antiretroviral drug design for the treatment of HIV-1 infected patients, thus the development of drug resistance has arisen as a major therapeutic and drug design challenge. To understand the molecular mechanisms leading to drug resistance we …
Further Reflections On Extinguishing The Fountainhead Of Knowledge: A Call To Transition To The "Innovation Policy" Narrative In Patent Law, Simone Rose
SMU Law Review
Economists are unable to provide a clear answer to how effective the patent system is in encouraging innovation. At best, they point to certain sectors, such as pharmaceutical and biotechnology, which benefit from a robust patent scheme. Conversely, sectors such as software and, ironically at the same time, biotechnology may be harmed by an overly broad patent scheme. The question emerges: Why do the various stakeholders in all industrial sectors, Congress, the Patent and Trademark Office ("PTO"), and the courts (in particular, the Federal Circuit) continue to center the development of patent law around the "innovation presumption" despite the lack …

Environment and Society Faculty Publications
Since the Uintah Basin Research Conference in 2007, residents of the area have witnessed a consistent level of land-use development throughout the region. Portions of that growth and development have precipitated the need to develop a landscape-level plan in order to maintain the context of their region and community identity in the coming years. The purpose of this study is to research and develop a process that identifies current and future land-use issues throughout the Uintah Basin. The identification of these issues by various stakeholders will help to provide a framework for future policy decisions.

Purpose: This study investigated ocular surface components that contribute to matrix-metalloproteinase (MMP)-2 and MMP-9 found in tears following corneal epithelial wounding.
Methods: Laboratory short-haired cats underwent corneal epithelial debridement in one randomly chosen eye (n = 18). Eyeflush tears were collected at baseline and during various healing stages. Procedural control eyes (identical experimental protocol as wounded eyes except for wounding, n = 5) served as controls for tear analysis. MMP activity was analyzed in tears using gelatin zymography. MMP staining patterns were evaluated in ocular tissues using immunohistochemistry and used to determine MMP expression sites responsible for tear-derived MMPs.

Background: The cancer stem cell (CSC) theory proposes that tumours arise from and are sustained by a subpopulation of cells with both cancer and stem cell properties. One of the key hallmarks of CSCs is the ability to grow anchorage-independently under serum-free culture conditions resulting in the formation of tumourspheres. It has further been reported that these cells are resistant to traditional chemotherapeutic agents.
Methods: In this study, the tumoursphere assay was validated in MCF-7 cells and used to screen novel marine algal compounds for potential anti-cancer stem cell (CSC) activity in vitro.
Results: MCF-7 breast cancer cells were observed …

Embodied Conflict Resolution: Resurrecting Roleplay-Based Curricula Through Dance, Nadja Alexander, Michelle Lebaron
Research Collection Yong Pung How School Of Law
Moving on from the authors’ seminal 2009 critique of the overuse of role-plays in negotiation teaching, "Death of the Role-Play" (chapter 13 in Rethinking Negotiation Teaching), Alexander and LeBaron have taken the rapidly increasing enthusiasm for experiential learning in a new direction: multiple intelligences. Their particular interest is in a use of experiential learning that focuses on kinesthetic intelligence, employing actual physical movement, particularly dance, to unlock creativity in other mental domains, as well as to encourage authentic participation by people whose skills are not primarily verbal or mathematical. Those who may be inclined to be skeptical should note that …

Breastmilk protects infants against infections; however, specific responses of breastmilk immune factors to different infections of either the mother or the infant are not well understood. Here, we examined the baseline range of breastmilk leukocytes and immunomodulatory biomolecules in healthy mother/infant dyads and how they are influenced by infections of the dyad. Consistent with a greater immunological need in the early postpartum period, colostrum contained considerable numbers of leukocytes (13–70% out of total cells) and high levels of immunoglobulins and lactoferrin. Within the first 1–2 weeks postpartum, leukocyte numbers decreased significantly to a low baseline level in mature breastmilk (0–2%) …

BACKGROUND: Effective malaria vector control targeting indoor host-seeking mosquitoes has resulted in fewer vectors entering houses in many areas of sub-Saharan Africa, with the proportion of vectors outdoors becoming more important in the transmission of this disease. This study aimed to develop a gravid trap for the outdoor collection of the malaria vector Anopheles gambiae s.l. based on evaluation and modification of commercially available gravid traps. METHODS: Experiments were implemented in an 80 m(2) semi-field system where 200 gravid Anopheles gambiae s.s. were released nightly. The efficacy of the Box, CDC and Frommer updraft gravid traps was compared. The Box …

The H355A, H355K, H80A, and H80K mutant enzymes of the argE-encoded N-acetyl-L-ornithine deacetylase (ArgE) from Escherichia coli were prepared, however, only the H355A enzyme was found to be soluble. Kinetic analysis of the Co(II)-loaded H355A exhibited activity levels that were 380-fold less than Co(II)-loaded WT ArgE. Electronic absorption spectra of Co(II)-loaded H355A-ArgE indicate that the bound Co(II) ion resides in a distorted, five-coordinate environment and Isothermal Titration Calorimetry (ITC) data for Zn(II) binding to the H355A enzyme provided a dissociation constant (Kd) of 39 μM. A three-dimensional homology model of ArgE was generated using the …

Phosphomevalonate kinase (PMK) phosphorylates mevalonate-5-phosphate (M5P) in the mevalonate pathway, which is the sole source of isoprenoids and steroids in humans. We have identified new PMK inhibitors with virtual screening, using autodock. Promising hits were verified and their affinity measured using NMR-based 1H–15N heteronuclear single quantum coherence (HSQC) chemical shift perturbation and fluorescence titrations. Chemical shift changes were monitored, plotted, and fitted to obtain dissociation constants (Kd). Tight binding compounds with Kd’s ranging from 6–60 μM were identified. These compounds tended to have significant polarity and negative charge, similar to the natural …
