Introduction: Retrotransposons (REs) constitute nearly half of the genome and include long terminal repeat (LTR) elements, Long INterspersed Elements (LINE), and Short INterspersed Elements (SINE). REs are typically silenced in somatic tissues via DNA methylation but can be reactivated through DNA hypomethylation, potentially impacting gene regulation. Here, we investigate genome-scale profiles of RE methylation in high-grade serous ovarian carcinoma (HGSOC) and associations with survival among Black women.

Methods: Methylation levels of LTR, LINE-1, and Alu (type of SINE) in 200 HGSOC tumors were predicted using a random forest approach and clustered using multiple consensus algorithms. Associations between RE methylation clusters …

Precision medicine in oncology is an evolving therapeutic approach that leverages genetic, clinical, and biomarker data to tailor treatments to individual patients. This review explores the three core pillars of modern precision oncology: targeted therapy, immunotherapy, and the integration of artificial intelligence (AI) into clinical practice. Targeted therapies, including monoclonal antibodies and antibody-drug conjugates, selectively inhibit molecular pathways involved in tumor growth. While conventional chemotherapy remains the backbone of treatment and has improved remission rates, its cytotoxic nature limits broader applicability and increases the risk of comorbidities. Immunotherapies, particularly immune checkpoint inhibitors and chimeric antigen receptor T-cell therapies, have transformed …

Extended-Release Buprenorphine With Bupivacaine Effectively Provides Postoperative Analgesia In A Mouse Laparotomy Model, Monika K. Huss, Amber Kerk, Renee Cotton, Helen Chum, Michael Hsieh, Katechan Jampachaisri, Patrick Sharp, Cholowat Pacharinsak

The Thai Journal of Veterinary Medicine

Multimodal analgesia is widely encouraged for major survival surgery. This facilitates lower doses of individual drugs, thereby reducing side effects. Extended-release analgesics offer sustained analgesia coverage, prevent drug dosing nadirs, and reduce stress. Studies evaluating multimodal and extended-release analgesia combinations for major survival surgery in mice are limited. We compared the analgesic effect of bupivacaine and extended-release buprenorphine (Bupi-ER) to bupivacaine and buprenorphine HCl (Bupi-HCl). We hypothesized that preoperative Bupi-ER would provide more effective analgesia than Bupi-HCl. Mice were randomly assigned to 1 of 2 treatment groups: bupivacaine (2 mg/kg, local infiltration, once) with either 1) extended-release buprenorphine (0.6 mg/kg, …

Inequality And Covid Risk At School: Racial Disparities In Indoor Density, Vaccination Rates, And Consequences For Absenteeism, Michael C. Quinn, Michah W. Rothbart, Amy Ellen Schwartz, Brian Elbel

Center for Policy Research

During the COVID pandemic, schools were widely believed to be a venue that facilitated disease transmission. While some worried Black and Hispanic students would disproportionately face greater risk of COVID exposure at school (school COVID risk) – given well-documented racially disparate school environments and resources – little empirical evidence exists documenting or refuting potential disparities in school COVID risk. This paper begins to fill this gap by examining racial disparities in the school environments that contribute to COVID risk at school—specifically, vaccination rates and classroom space per pupil (indoor density) - in New York City elementary schools. We then document …

Microneedle-Based Lc-Ms/Ms Profiling Of Dermal Interstitial Fluid Reveals Early Lipid Dysregulation Contributing To Painful Neuropathy In Prediabetic And Type 2 Diabetic Rats, Srinivasa Rao Gadam

Biomedical Sciences ETDs

Painful diabetic neuropathy (PDN), a complication of type 1 and type 2 diabetes, also occurs in obesity and prediabetes, with dyslipidemia as a modifiable risk factor. The distal-to-proximal neuropathy pattern and length-dependent intraepidermal nerve fiber loss suggest peripheral contributions. We hypothesized that elevated neurotoxic lipid intermediates—diacylglycerols (DAG), free fatty acids (FFA), and acylcarnitines (CARs)—in the dermal interstitial fluid (ISF) drive metabolism-associated hyperalgesia in prediabetic and diabetic rats. Using a microneedle array (MIA) with LC-MS/MS, we profiled ISF and serum lipids from high-fat diet (HFD) and HFD + streptozotocin (STZ) rat models alongside Hargreaves testing. ISF lipid changes appeared earlier (weeks …
