Behaviors That Predict Personality Components In Adult Free-Ranging Tibetan Macaques (Macaca Thibetana), Alexander J. Pritchard, Lori K. Sheeran, Kara I. Gabriel, Jin-Hua Li, Ronald S. Wagner

Anthropology and Museum Studies Faculty Scholarship

To further the potential for applied personality studies, we present a methodology for assessing personality in nonhuman animals without a priori assumptions, using behavioral measures to discriminate personality survey results. Our study group consisted of 12 free-ranging, provisioned, adult Tibetan macaques (Macaca thibetana) at the Valley of the Wild Monkeys, China. We asked familiar Chinese park guards and scientists to rate each of the 12 macaques using 27-item personality surveys. We also recorded behavioral observations (> 100 hrs) from August–September, 2012. The personality surveys showed reliability in 22 of the items that were then utilized in a principal component analysis …

A Metapopulation Model For Sylvatic T. Cruzi Transmission With Vector Migration, Christopher Kribs, Britnee Crawford

Mathematics Faculty Publications - Archive

This study presents a metapopulation model for the sylvatic transmission of Trypanosoma cruzi, the etiological agent of Chagas' disease, across multiple geographical regions and multiple overlapping host-vector transmission cycles. Classical qualitative analysis of the model and several submodels focuses on the parasite's basic reproductive number, illustrating how vector migration across patches and multiple transmission routes to hosts (including vertical transmission) determine the infection's persistence in each cycle. Numerical results focus on trends in endemic [equilibrium] persistence levels as functions of vector migration rates, and highlight the significance of the different epidemiological characteristics of transmission in each of the three regions.

The Neotropical Genus Austrolebias: An Emerging Model Of Annual Killifishes, Nibia Berois, María J. Arezo, Rafael O. De Sá

Biology Faculty Publications

Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life.

Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the …

Assessing Rodent Species Counts And Diversity In The Not-Grazed Montana De Oro State Park And The Rotationally Grazed Pecho Ranch, Nancy Marie Lemos

Master's Theses

The available data examining the influence of rotational grazing on rodent responses are limited. This study investigated how rotational livestock grazing practices influence small mammal rodent abundances and species diversity. We looked for evidence of variation in the occurrence and/or numbers of certain rodent species among three plant community types (grassland, shrubland, grass-shrub mix), managed with or without grazing. We used Sherman live traps over a total of eight trapping sessions. We totaled 486 trapnights for each of the six plant community and grazing management combinations. The three plant community types were identified by visual cover.

Out of the eight …

Robotic Hand Controlled By Myoelectric Signals, Kyle T. Staskus, Daniel A. O'Bryan

Electrical Engineering

In this project we developed a prosthetic hand that is controlled by myoelectric signals from the forearm. The forearm signals were filtered and amplified to be easier read by a microcontroller. The microcontroller then generated signals to control the mechanical hand based on these myoelectric input signals. This is done by the microcontroller increasing the pulse width sent to several servos making up the hand. The larger the pulse width the more flexed the hand becomes until it reaches the maximum programmed into it. In order to open the hand the high input to the microcontroller must be deactivated and …

The Intersection Between Hpv And Hiv Infections: Is There An Increased Susceptibility To Hiv Acquisition In Hpv-Infected Women?, Montida Fleming, Ba, Fred Gorstein, Md

Department of Pathology Honors Program Student Research Symposium

It has been well documented that HIV infection is associated with HPV infection and the progression to cervical carcinoma. Since the spread of HIV/AIDS epidemic, HPV-related cervical carcinoma had such a high prevalence in HIV-infected individuals that it became established as an AIDS-defining illness. Cervical cancer is the most common AIDS-related malignancy, and the sixth most common presenting AIDS-defining illness in women.¹ Additionally, HIV infection leads to a 5-fold increase in multiple new HPV infections within 6 weeks of seroconversion.² Not only does HIV impact acquisition of HPV at molecular and cellular levels, HIV and HPV viruses interact …

Lead Toxicity: What Is It And How Is It Happening?, Kimberly A. Parada, Ba, Jay S. Schneider, Phd

Department of Pathology Honors Program Student Research Symposium

EPIDEMIOLOGY

Lead poisoning accounts for 0.6% of the global burden of disease.

In Pennsylvania in 2010, 148,751 children under 72 months of age were tested for blood lead levels. Of those children, 19,176 had blood lead levels greater than 5 μg/dl.

• A lower socioeconomic status increases the chances for lead exposure.
• Lead toxicity is an under-appreciated problem that is entirely preventable.

Peripheral T-Cell Lymphoma Arising From Age-Related Ebv-Associated Lymphoproliferative Disorder (Ar-Ebvlpd), Alaina Chodoff, Msii, Guldeep Uppal, Md, Jerald Z. Gong, Md

Department of Pathology Honors Program Student Research Symposium

In the setting of underlying immune suppression, Epstein Barr Virus (EBV) is a well-recognized oncogenic agent that induces the malignant proliferation of B-cells. EBV-lymphoproliferative disorders (LPDs) have recently been linked to immunosenescence. We present a unique case of Age-Related EBV-Lymphoproliferative Disorder (AR-EBVLPD) in a 70 year old female that deviates from the characteristic progression of this disease. Over the course of 18 months, the patient’s clinical condition worsened without a definitive diagnosis to explain the severe, atypical widespread chronic inflammation spanning her gastrointestinal tract, from esophagus to small bowel. The diagnosis of AR-EBVLPD, polymorphic extranodal subtype, was delayed until the …

Hiv Associated Neurocognitive Disorders In An Antiretroviral Therapy Era, Molly Halloran, David S. Strayer, Md, Phd

Department of Pathology Honors Program Student Research Symposium

HIV emerged as a major threat to world health over 30 years ago, and while its effects on the immune system are widely known, HIV also has broad and devastating effects on the nervous system. Despite our potent antiretroviral therapies (ART), these HIV-associated neurocognitive disorders (HAND) continue to afflict HIV infected individuals. With over 33 million people infected worldwide and evidence that neurological damage can accrue in virologically well controlled individuals, HAND is a pressing challenge. Nevertheless, many questions remain unanswered about this spectrum of disorders.

Molecular Profiling Of Patients With Non Small Cell Lung Cancer At Jefferson University Hospital, Erin Bange, Renu Bajaj, Ms, Phd, Cg (Ascp), Cm, Facmg

Department of Pathology Honors Program Student Research Symposium

Companion diagnostics is the use of specific tests whose results are linked to a particular drug. It allows clinicians the ability to better target the mechanism of pathology in the patient and follow it up with a therapy specifically designed to treat the disease process at hand. This approach to medicine has particularly been championed in the field of oncology with the development of such drugs as Zelboraf for the treatment of metastatic melanoma with the BRAFV600 mutation or Xalkori for late stage lung cancer expressing an abnormal ALK protein. In the case of non-small cell lung cancer (NSCLC) Jefferson …

Plasmapheresis And Hiv-Associated Thrombotic Microangiopathy: An Institutional Review, Megan Fisher, Ms2, Nancy Edger Hall, Rn, Mba, Jennifer Webb, Md, Julie Karp, Md

Department of Pathology Honors Program Student Research Symposium

Thrombotic thrombocytopenic purpura (TTP) is a systemic disorder that classically results from a deficiency in the von Willebrand factor-cleaving enzyme, ADAMTS13. The human immunodeficiency virus (HIV) is a secondary cause of TTP. It has been recognized that some patients with HIV-associated TTP do not have a deficiency in ADAMTS13 activity. The role of plasmapheresis (PLEX) in these patients is unclear. This study reviewed 8 cases of HIV-associated TTP at Thomas Jefferson University Hospital. All patients responded to treatment; however, we were unable to make any conclusions regarding the use of PLEX in patients with normal ADAMTS13 activity. HAART initiation is …

Haploidentical Hematopoietic Stem Cell Transplantation: Rationale, Development, And Jefferson’S Method, Susan Mcilvaine, Dolores Grosso, Rn, Crnp, Dnp, Beth Colombe

Department of Pathology Honors Program Student Research Symposium

INTRODUCTION

There are many indications for hematopoietic stem cell transplantation. In addition to hematologic malignancies, transplants are performed in certain non-hematologic malignancies, for marrow disorders such as Sickle Cell Anemia, and for various inherited disorders such as SCID. Traditionally, transplants have been performed between donors and recipients that are a complete HLA match (typically matched siblings). That is, patients have identical HLA alleles on both copies of chromosome 6. HLA alleles code for major histocompatibility complex molecules, which are the proteins that cause transplant rejection when a mismatch between donor and recipient is present. Thus, matched transplants have been historically …

Small Cell Carcinoma Of The Bladder: A Rare Entity, Andrew H. Matthews, Ruth Birbe, Md

Department of Pathology Honors Program Student Research Symposium

BACKGROUND

Primary small cell carcinoma of the urinary bladder is a rare tumor, accounting for less than 1% of the annual 70,000 cases of urinary bladder cancer.¹ Accordingly, little data is available beyond case series to guide diagnosis or treatment. Overall prognosis remains poor with five year survival often markedly below 50%. Current staging and treatment remains largely based on extrapolation from small cell carcinoma of the lung. We review two recent cases of bladder small cell carcinoma with a focus on comparing and contrasting with lung small carcinoma.

Giant Cell Tumor Of Soft Tissue: A Case Study, Rachel Schneider, Brian J. O'Hara

Department of Pathology Honors Program Student Research Symposium

BACKGROUND

Giant cell tumors of soft tissue are relatively uncommon tumors. They are considered to be the soft tissue counterpart to giant cell tumors of bone. Both tumors consist of multi-nucleated giant cells evenly distributed throughout a background of epithelioid mononuclear cells, and are usually benign, but can be locally invasive. Giant cell tumors of soft tissue typically occur in patients over age 40, and show no gender or racial predilection. They present as firm, well demarcated masses, which are not connected to the underlying muscle, tendon, or bone. Giant cell tumors of soft tissue are generally small, and tend …

Small Cell Carcinoma Of The Breast, Victor Carlson, Paolo Cotzia, Md, Juan P. Palazzo, Md

Department of Pathology Honors Program Student Research Symposium

INTRODUCTION

Small cell carcinoma of the breast (SCCB) is a rare, highly aggressive neoplasm first reported in 1983. With striking histologic similarity to small cell carcinoma of the lung, it is comprised of small cells with relatively large, hyperchromatic nuclei and scanty cytoplasm. While capable of hormone secretion, this is a rare occurrence in this variant of small cell carcinoma. Patients typically present with a suspicious breast mass confirmed on imaging, with variable lymph node invasion.

Mir-221/222 Promotes S-Phase Entry And Cellular Migration In Control Of Basal-Like Breast Cancer., Yuan Li, Chunli Liang, Haizhong Ma, Qian Zhao, Ying Lu, Zhendong Xiang, Li Li, Jie Qin, Yihan Chen, William C Cho, Richard G Pestell, Li Liang, Zuoren Yu

Department of Cancer Biology Faculty Papers

The miR-221/222 cluster has been demonstrated to function as oncomiR in human cancers. miR-221/222 promotes epithelial-to-mesenchymal transition (EMT) and confers tamoxifen resistance in breast cancer. However, the effects and mechanisms by which miR-221/222 regulates breast cancer aggressiveness remain unclear. Here we detected a much higher expression of miR-221/222 in highly invasive basal-like breast cancer (BLBC) cells than that in non-invasive luminal cells. A microRNA dataset from breast cancer patients indicated an elevated expression of miR-221/222 in BLBC subtype. S-phase entry of the cell cycle was associated with the induction of miR-221/222 expression. miRNA inhibitors specially targeting miR-221 or miR-222 both …

“Tengo Que Habla Español. Yo No Entiendo Ingles!”: A Qualitative Case Study On A Bilingual Child With Autism Spectrum, Hyun Uk Kim, Marilyn Roberti

The Journal of Special Education Apprenticeship

Language differences in children with Autism Spectrum Conditions (ASC) often lead professionals to believe that children with ASC cannot or should not become bilingual, thus advising parents with a child with ASC raised in a bilingual household to adhere to English only. Emerging studies, however, attest that children with ASC can become bilingual, and that there are no language differences between bilingual and monolingual children with ASC. Although these findings are promising, very few studies investigated external factors, such as cultural expectations, school practices and other pertinent factors involved in raising and educating children with ASC bilingually. Drawing from video-and …

To Be A Man: A Re-Assessment Of Black Masculinity In Lorraine Hansberry's A Raisin In The Sun And Les Blancs, Julie M. Burrell

English Faculty Publications

The first Black woman to pen a Broadway play, Lorraine Hansberry scripted a majority of male protagonists. Critics tend to see Hansberry’s depiction of Black men as either an unfortunate departure from her feminist concerns, or as damaging representations of Black masculinity. In contrast to such views, this essay maps the trajectory of Hansberry’s career-long project of scripting positive visions of Black masculinity, from the politically progressive, while still patriarchal, structures of masculinity in A Raisin in the Sun, to the heterogeneous performances of revolutionary masculinity in Les Blancs. Further, in her role as public intellectual, Hansberry questioned prevailing assumptions …

Multi-Scale Habitat Use Of Male Ruffed Grouse In The Black Hills National Forest, Cassandra L. Mehls, Kent C. Jensen, Mark A. Rumble, Michael C. Wimberly

The Prairie Naturalist

Ruffed grouse (Bonasa umbellus) are native upland game birds and a management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest (Black Hills). Our objective was to assess resource selection of male ruffed grouse to identify the most appropriate scale to manage for aspen and ruffed grouse in the Black Hills. During spring 2007 and 2008, we conducted drumming surveys throughout the central and northern Black Hills to locate used and unused sites from which we compared habitat characteristics at increasing spatial scales. Aspen with >70% overstory canopy cover (OCC) was important to the occurrence of …

Sauger Life History In The Lower Portion Of The Upper Mississippi River, Kasey L. Yallaly, Justin R. Seibert, Sara J. Tripp, David P. Herzog, Quinton E. Phelps

The Prairie Naturalist

Widespread declines have been observed in numerous riverine fish species due to a host of anthropogenic related perturbations such as channelization, dam creation, and exploitation (Graham 1997, Gerken and Paukert 2009). Understanding life history and population demographics of riverine fishes is critical to their conservation. Specific to our study, the Mississippi River has undergone extensive habitat modifications that have changed the Upper Mississippi River (UMR) from a typical lotic large, free flowing river to multiple reservoir-like pools with reduced flow (LePage 1980, Hurley et al. 1987). These habitat transformations may impact sauger (Sander canadensis) populations within the Mississippi River. Several …
