Faculty, Staff and Student Publications

INTRODUCTION: Citrate-phosphate-dextrose (CPD) is the most common anticoagulant for blood product storage in the United States. It was developed to prolong shelf life, though there is little research regarding its impact on function following transfusion. We used flow cytometry (FC), thromboelastography (TEG), and a clot contraction assay called the zFlex platform to measure platelet activation and global clot formation in blood samples anticoagulated with either CPD or in a standard blue top citrate (BTC) tube.

METHODS: Samples were obtained through venipuncture of the antecubital fossa from healthy donors who had not recently taken antiplatelet medication. Samples for FC analysis were …

Gendered Lives, Gendered Vulnerabilities: An Intersectional Gender Analysis Of Exposure To And Treatment Of Schistosomiasis In Pakwach District, Uganda, Sarah N. Ssali, Rosemary Morgan, Salama Nakiranda, Christopher Opio, Mariam Otmani Del Barrio

Internal Medicine, East Africa

Introduction: Schistosomiasis is a neglected tropical disease (NTD) that is endemic in Uganda, despite several interventions to eliminate it. It is transmitted when people infected with it pass on their waste matter into fresh water bodies used by others, consequently infecting them. Several studies have demonstrated gender and age differences in prevalence of schistosomiasis and NTDs such as lymphatic filariasis and soil transmitted helminths. However, few intersectional gender analysis studies of schistosomiasis have been undertaken. Using the World Health Organisation (WHO)’s intersectional gender analysis toolkit, this study was undertaken to identify which social stratifiers most intersected with gender to influence …

Phenytoin-Induced Cerebellar Atrophy: A Case For Reversibility Of Neurological Decline, Edwin Mogere, Davis Cheruiyot, Manakhe Nassiuma

General Surgery, East Africa

This case serves as a reminder of the infrequent, yet consequential occurrence of cerebellar degeneration linked to phenytoin usage. Whilst emphasizes the importance of monitoring patients on long-term phenytoin therapy, and it further suggests considering employing bedside imaging tools such as Ultrasound fusion imaging for follow-up of patients at risk of this type of disorder. We present a case study involving a 23-year-old woman who experienced significant neurological impairment resulting in severe cerebellar atrophy while undergoing phenytoin treatment. On cessation of phenytoin, the patient exhibited improvement with enhanced cerebellar function.

Human cytomegalovirus (HCMV) is an important pathogen for which new antiviral drugs are needed. HCMV, like other herpesviruses, encodes a nuclear egress complex (NEC) composed of two subunits, UL50 and UL53, whose interaction is crucial for viral replication. To explore whether small molecules can exert selective antiviral activity by inhibiting NEC subunit interactions, we established a homogeneous time-resolved fluorescence (HTRF) assay of these interactions and used it to screen >200,000 compound-containing wells. Two compounds, designated GK1 and GK2, which selectively inhibited this interaction in the HTRF assay with GK1 also active in a co-immunoprecipitation assay, exhibited more potent anti-HCMV activity …

The central dogma of molecular biology dictates the general flow of molecular information from DNA that leads to a functional cellular outcome. In skeletal muscle fibers, the extent to which global myonuclear transcriptional alterations, accounting for epigenetic and post-transcriptional influences, contribute to an adaptive stress response is not clearly defined. In this investigation, we leveraged an integrated analysis of the myonucleus-specific DNA methylome and transcriptome, as well as myonuclear small RNA profiling to molecularly define the early phase of skeletal muscle fiber hypertrophy. The analysis of myonucleus-specific mature microRNA and other small RNA species provides new directions for exploring muscle …

Next-Generation Chimeric Antigen Receptors For T- And Natural Killer-Cell Therapies Against Cancer, Ye Li, Katayoun Rezvani, Hind Rafei

Faculty, Staff and Student Publications

Adoptive cellular therapy using chimeric antigen receptor (CAR) T cells has led to a paradigm shift in the treatment of various hematologic malignancies. However, the broad application of this approach for myeloid malignancies and solid cancers has been limited by the paucity and heterogeneity of target antigen expression, and lack of bona fide tumor-specific antigens that can be targeted without cross-reactivity against normal tissues. This may lead to unwanted on-target off-tumor toxicities that could undermine the desired antitumor effect. Recent advances in synthetic biology and genetic engineering have enabled reprogramming of immune effector cells to enhance their selectivity toward tumors, …

Timely repair of chromosomal double-strand breaks is required for genome integrity and cellular viability. The polymerase theta-mediated end joining pathway has an important role in resolving these breaks and is essential in cancers defective in other DNA repair pathways, thus making it an emerging therapeutic target1 It requires annealing of 2-6 nucleotides of complementary sequence, microhomologies, that are adjacent to the broken ends, followed by initiation of end-bridging DNA synthesis by polymerase θ. However, the other pathway steps remain inadequately defined, and the enzymes required for them are unknown. Here we demonstrate requirements for exonucleolytic digestion of unpaired 3' tails …

Supraventricular Tachycardia Associated With Repeat Cesarean Section Under Spinal Anesthesia., Mihir Patel, Matthias Franzen, Camille D Hawkins, Matthew Brown, Samir Patel

Heart and Vascular Articles

Supraventricular tachycardia (SVT) is the most common tachyarrhythmia of pregnancy. Catecholamine surges, the use of vasoactive agents during delivery, and increased cardiac output during pregnancy are the most common contributing factors to developing SVT. SVT is usually benign in presentation but can lead to more serious arrhythmias in patients with a history of mitral stenosis secondary to rheumatic heart disease. When an SVT is detected, organic heart causes should be ruled out first. Symptoms of SVT include shortness of breath, palpitations, syncope, sweating, chest pain, and dizziness. In patients who are refractory to pharmacologic management and hemodynamically unstable, electrical cardioversion …
