Enhancing Data Science and Genomics Capacity of a Historically Black Medical College Through Interdisciplinary Training and Research Collaborations.

As data grows exponentially across diverse fields, effectively leveraging big data has become increasingly crucial. In data science and computational genomics, however, minority groups, including African Americans, are significantly underrepresented, coupled with the lack of resources and infrastructure in minority-serving institutions. This paper summarizes the second phase of our funded project that aims to enhance the data science capacity of Meharry Medical College (MMC), a Historically Black College/University (HBCU), by providing training and fostering collaborations between data scientists and researchers in basic science and biomedical fields.

Differential Effector Function of Tissue-Specific Natural Killer Cells against Lung Tumors.

Introduction: Natural killer (NK) cells are innate lymphoid cells capable of directly killing target cells while modulating immune effector responses. Despite their multifunctional capacities, a limited understanding of their plasticity and heterogeneity has impeded progress in developing effective NK cell-based cancer therapies. In this study, we investigated NK cell tissue heterogeneity in relation to their phenotype and effector functions against lung tumors.

pSATdb 2.0: a database of organellar common, polymorphic, and unique microsatellites.

Microsatellites, or simple sequence repeats (SSRs), are repetitive DNA sequences typically composed of 1-6 nucleotides. These repetitive sequences are found in almost all genomes, including chloroplasts and mitochondria, and are widely distributed throughout the genomes. Microsatellites are highly polymorphic, and their length may differ from species to species.

Quantitative phase imaging endoscopy with a metalens.

Quantitative phase imaging (QPI) recovers the exact wavefront of light from intensity measurements. Topographical and optical density maps of translucent microscopic bodies can be extracted from these quantified phase shifts. We demonstrate quantitative phase imaging at the tip of a coherent fiber bundle using chromatic aberrations inherent in a silicon nitride hyperboloid metalens.

Harnessing Brainwave Entrainment: A Non-invasive Strategy To Alleviate Neurological Disorder Symptoms.

From 1990-2019, the burden of neurological disorders varied considerably across countries and regions. Psychiatric disorders, often emerging in early to mid-adulthood, are linked to late-life neurodegenerative diseases like Alzheimer's disease and Parkinson's disease. Individuals with conditions such as Major Depressive Disorder, Anxiety Disorder, Schizophrenia, and Bipolar Disorder face up to four times higher risk of developing neurodegenerative disorders.

Design Justice, a Counternarrative to Dominant Approaches in Medical Education.

Phenomenon: Marginalized individuals in medicine face many structural inequities which can have enduring consequences on their progress. Therefore, inequity must be addressed by dismantling underlying unjust policies, environments, and curricula. However, once these injustices have been taken apart, how do we build more just systems from the rubble? Many current strategies to address this question have foundational values of urgency, solutionism, and top-down leadership.

Coexistence of pulmonary thromboembolism and pulmonary tuberculosis: a diagnostic dilemma.

A man in his early 50s with previously treated pulmonary tuberculosis (TB) presented with a 3-month history of cough, expectoration and progressive breathlessness, accompanied by significant weight loss. Examination revealed tachycardia, tachypnoea, hypoxaemia and unilateral diminished breath sounds. Investigations showed anaemia, leucocytosis and a homogeneous opacity on the left side of the CXR.

Anti-DEFA5 Monoclonal Antibody Clones 1A8 and 4F5 Immunoreactive Bioassay for Diagnosing Inflammatory Bowel Disease.

Background: Robust evidence suggests that the aberrant expression of α defensin 5 protein (DEFA5) in colon inflammatory bowel diseases (IBDs) underlies the distinct pathogenesis of Crohn's colitis, can be exploited as a reliable diagnostic biomarker to differential diagnosis of Crohn's colitis (CC) from Ulcerative colitis (UC) in otherwise indeterminate colitis (IC). We evaluated the specificity of the commercially available anti-DEFA5 antibodies and showed further validation of their appropriateness for a given application is required.

Methods: We established two mouse monoclonal DEFA5 antibody clones 1A8 and 4F5 by immunizing the mice with purified recombinant protein and validated the specificity, selectivity and cross reactivity in recognizing the endogenous and recombinant DEFA5 protein, especially for Immunohistochemistry, Western blot, Immunoprecipitation, or enzyme-linked immunosorbent assay.

Loss of Mitochondrial Tusc2/Fus1 Triggers a Brain Pro-Inflammatory Microenvironment and Early Spatial Memory Impairment.

Brain pathological changes impair cognition early in disease etiology. There is an urgent need to understand aging-linked mechanisms of early memory loss to develop therapeutic strategies and prevent the development of cognitive impairment. Tusc2 is a mitochondrial-resident protein regulating Ca fluxes to and from mitochondria impacting overall health.

Cannabinoid hyperemesis syndrome co-occurring with superior mesenteric artery syndrome in adolescents.

Objectives: Both superior mesenteric artery syndrome (SMAS) and cannabinoid hyperemesis syndrome (CHS) may present with abdominal pain, nausea, and emesis - making them difficult to differentiate or determine when they co-occur in adolescents who regularly use cannabis. Here, we present nine cases of CHS co-occurring with SMAS and characterize their clinical courses.

Methods: Patients admitted at Children's Hospital of Colorado between January 1, 2015, and March 23, 2023, who had both cannabis use (F12.

Effects of Topoisomerase II alpha Inhibition on Oral Cancer Cell Metabolism and Cancer Stem Cell Function.

Background: Topoisomerase IIα (TOP2A), is an enzyme involved in DNA replication, transcription, recombination, and chromatin remodeling and is found in a variety of cancers. However, the role of TOP2A regulation in oral cancer progression is not fully explained. We investigated the effect of TOP2A inhibition on cell survival, metabolism, and cancer stem cell self-renewal function in oral cancer cells.

Neoantigen Identification and Dendritic Cell-Based Vaccines for Lung Cancer Immunotherapy.

Immunotherapies can treat many cancers, including difficult-to-treat cases such as lung cancer. Due to its tolerability, long-lasting therapeutic responses, and efficacy in a wide spectrum of patients, immunotherapy can also help to treat lung cancer, which has few treatment choices. Tumor-specific antigens (TSAs) for cancer vaccinations and T-cell therapies are difficult to discover.

The Diaspora Human Genomics Institute Launches the Initiative: A Transformative, Historic Partnership to Ensure Health Equity in a Time of Unprecedented Technological Advancements.

Human subjects research and drug and device development currently base their findings largely on the genetic data of the non-Hispanic White population, excluding People of Color. This practice puts People of Color at a distinct and potentially deadly disadvantage in being treated for sickness, disability, and disease, as seen during the COVID-19 pandemic. Major disparities exist in all chronic health conditions, including cancer.
