Effects Of Benzyl Isothiocyanate And Papain On The Hatching And Migration Of Equine Cyathostomes, Jessie Kmietsch

Undergraduate Honors Thesis Projects

Cyathostomes are widespread and can affect horses of any life stage. Many common anthelmintics are no longer effective at treating cyathostomes due to parasitic resistance. The objective of this in vitrostudy was to use egg hatch and larval migration tests to determine if compounds found in papaya seeds (papain or benzyl isothiocyanate) reduce cyathostome egg hatching and migration. The experiments were conducted between August 2016 and March 2018. Cyathostome eggs were obtained from horse fecal samples. Egg hatch tests were performed by adding papain and benzyl isothiocyanate (BITC) to wells separately at different concentrations in triplicate. After incubation, the …

Learning From Our Mothers: Examining The Role Of Intergenerational Knowledge Transfer In Advancing Gender Equity Among Sri Lankan Youth, Ruvani Fonseka, Samantha Hurst

Faculty Research, Scholarly, and Creative Activity

Background
In a 2013 survey, over half of Sri Lankan men and women expressed gender-inequitable attitudes that equated masculinity with violence, and femininity with obedience to men. High rates of gender-inequitable attitudes are a community-level risk factor for gender-based violence including rape and intimate partner violence. In Sri Lanka, public health practitioners focused on reducing the health disparities resulting from gender inequity need to better understand the processes by which gender-inequitable attitudes develop and how to prevent them. The goal of this research was to identify potential points of intervention at which appropriate programmes and policies could most effectively cultivate …

Cold Agglutinins In Peripheral Blood With Atypical Cells With An Owl-Eye Appearance In Bone Trephine, Ayesha Majeed Memon, Farheen Karim

Department of Pathology and Laboratory Medicine

Autoimmune hemolytic anemia (AIHA) is a form of hemolytic anemia in which red cells lysis occurs due to presence of an autoantibody. Association of AIHA is well known with lymphoproliferative disorders, especially with non-Hodgkin's lymphoma. However, AIHA in association with Hodgkin's lymphoma is seen occasionally. Of the AIHA associated with Hodgkin's lymphoma, most are of warm type or mixed type. Cold AIHA, as seen in our case, is very rare in Hodgkin's lymphoma.

Integrating Tuberculosis And Antimicrobial Resistance Control Programmes, Rumina Hasan, Sadia Shakoor, Johanna Hanefeld, Mishal Khan

Department of Pathology and Laboratory Medicine

Many low- and middle-income countries facing high levels of antimicrobial resistance, and the associated morbidity from ineffective treatment, also have a high burden of tuberculosis. Over recent decades many countries have developed effective laboratory and information systems for tuberculosis control. In this paper we describe how existing tuberculosis laboratory systems can be expanded to accommodate antimicrobial resistance functions. We show how such expansion in services may benefit tuberculosis case-finding and laboratory capacity through integration of laboratory services. We further summarize the synergies between high-level strategies on tuberculosis and antimicrobial resistance control. These provide a potential platform for the integration of …

Melas: A Complex And Challenging Diagnosis, Kumail Khandwala, Anwar Ahmad, Taha Sheikh

Department of Radiology

Mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a rare multisystem disorder and is the most common maternally inherited mitochondrial disease. This condition has a special predilection for the nervous system and muscles. Typical findings on brain imaging include stroke-like areas, calcification of basal ganglia and brain atrophy. This accounts for the disease being, both clinically and radiologically, mistaken for ischemic stroke. The differentiation features from stroke include comparatively young age of the patients, site of the lesions, and relative overlap between the cerebral vasculature territories. In this case report, we discuss a 16-year male with clinical and radiological …

"Technoference" And Implications For Mothers' And Fathers' Couple And Coparenting Relationship Quality., Brandon T. Mcdaniel Phd, Adam M Galovan, Jaclyn D Cravens, Michelle Drouin

Health Services and Informatics Research

Technology devices are widely used today, creating opportunities to connect and communicate with distant others while also potentially disrupting communication and interactions between those who are physically present (i.e., technoference or phubbing). These disruptions in couple and coparenting relationships have the potential to negatively impact relationship outcomes. In this two-part study of 182 married/cohabiting couples from the Daily Family Life Project and 239 couples from the Couple Well-Being Project, we examined the role of technoference in couple and coparenting relationship quality and potential gender differences utilizing dyadic data. We found that greater technoference related to greater conflict over technology …

Medical College Documents

We report an unusual case of an 18-year old woman, who presented to Civil Hospital Karachi in May 2016 with complaints of vomiting, abdominal pain, dysphagia, altered bowel habits, loss of appetite and chronic weight loss. On examination, abdomen was found to be soft and non-tender with discomfort on breathing. CT angiogram revealed reduction of aortomesenteric angle and aortomesenteric distance which were both consistent with superior mesenteric artery syndrome. Reduction in angle was thought to be because of weight loss and adipose tissue depletion so patient was started on enteral and parenteral nutritional supplements. Upon seeing little to no improvement, …

Mccormick, Jessica C. Seidman, Zeba Rasmussen, Margaret N. Kosek, Elizabeth T. Rogawski, William Petri, Anurahda Bose, Zulfiqar Ahmed Bhutta, Ali Turab

Department of Paediatrics and Child Health

Children in low-income countries experience multiple illness symptoms in early childhood. Breastfeeding is protective against diarrhea and respiratory infections, and these illnesses are thought to be risk factors of one another, but these relationships have not been explored simultaneously. In the eight-site MAL-ED study, 1,731 infants were enrolled near birth and followed for 2 years. We collected symptoms and diet information through twice-weekly household visits. Poisson regression was used to determine if recent illness history was associated with incidence of diarrhea or acute lower respiratory infections (ALRI), accounting for exclusive breastfeeding. Recent diarrhea was associated with higher risk of incident …

Vmpfc Activation During A Stressor Predicts Positive Emotions During Stress Recovery, Xi Yang, Katelyn M. Garcia, Youngkyoo Jung, Christopher T. Whitlow, Kateri Mcrae, Christian E. Waugh

Psychology: Faculty Scholarship

Despite accruing evidence showing that positive emotions facilitate stress recovery, the neural basis for this effect remains unclear. To identify the underlying mechanism, we compared stress recovery for people reflecting on a stressor while in a positive emotional context with that for people in a neutral context. While blood–oxygen-level dependent data were being collected, participants (N = 43) performed a stressful anagram task, which was followed by a recovery period during which they reflected on the stressor while watching a positive or neutral video. Participants also reported positive and negative emotions throughout the task as well as retrospective thoughts …

School of Medicine Publications

On average, patients with psychosis perform worse than controls on visual change-detection tasks, implying that psychosis is associated with reduced capacity of visual working memory (WM). In the present study, 79 patients diagnosed with various psychotic disorders and 166 controls, all African Americans, completed a change-detection task and several other neurocognitive measures. The aims of the study were to (1) determine whether we could observe a between-group difference in performance on the change-detection task in this sample; (2) establish whether such a difference could be specifically attributed to reduced WM capacity (k); and (3) estimate k in the …

Verbal Memory Performance And Reduced Cortical Thickness Of Brain Regions Along The Uncinate Fasciculus In Young Adult Cannabis Users, Nina Levar, Alan N. Francis, Matthew J. Smith, Wilson C. Ho, Jodi M. Gilman

School of Medicine Publications

Introduction: Memory impairment is one of the most commonly reported effects of cannabis use, especially among those who initiate use earlier, perhaps due to the effects of delta-9- tetrahydrocannabinol on cannabinoid (CB1) receptors in the brain. Studies have increasingly investigated whether cannabis use is associated with impairments in verbal memory, and with alterations in brain structures underlying verbal memory. The uncinate fasciculus (UF), a long-range white matter tract, connects regions with densely localized CB1 receptors that are important in verbal memory. This study investigated the impact of cannabis use on UF structures and its association with memory performance in young …
