Immunotherapy has yet to demonstrate durable efficacy in pancreatic ductal adenocarcinoma (PDAC) despite the fact that pancreatic cancer cells have higher levels of immune checkpoint expression than other cancer cell types in which immunotherapy efficacy has been well established. We observed effective cytotoxicity with the combination therapy of pembrolizumab (an anti-PD-1 monoclonal antibody, mAb) and cabozantinib (an anti-MET small molecule) in vivo. This served as the basis for an investigator-initiated phase II clinical trial (NCT05052723). The trial was open to patients with treatment-refractory metastatic PDAC with a single-arm treatment protocol of pembrolizumab and cabozantinib. Here, we report the case of …

A Unique Protein Adjuvant For Precision Immunotherapy To Prevent Recurrence Of Surgically Resected Colorectal Cancer, Yasuhiro Suzuki, Rajesh Mani, B. Mark Evers

Markey Cancer Center Faculty Publications

Effectively activating protective CD8+ T cell immunity specifically against cancer antigens is an important pathway to prevent the growth of various types of cancers. A major obstacle in this approach is variations in cancer antigens among patients. A valuable material to overcome the antigen variation among cancer patients is the use of each individual’s own cancer cells for immunization. In colorectal cancer (CRC), approximately one-third of the patients who receive curative surgical resection have a recurrence of cancer. Therefore, the use of surgically resected CRC for immunotherapy to specifically activate the protective CD8+ T cells against their own …

The Effect Of Cover Crop Management Strategies On Nutrient Availability In No-Till Corn, Emily C. Marsh Jan 2026

The Effect Of Cover Crop Management Strategies On Nutrient Availability In No-Till Corn, Emily C. Marsh

Theses and Dissertations--Plant and Soil Sciences

Cover crops are reported to have long-term soil health improvements, one of which is reducing erosion. However, popular cereal cover crops, such as rye (Secale cereale L.), have the potential to cause a yield penalty in the following corn (Zea mays L.) crop due to a reduction in available nitrogen. Legumes, such as Austrian winter pea (Pisum sativum L. var. arvense), are thought to reduce this yield penalty due to their capacity to fix nitrogen. Sulfur is another nutrient of interest, especially as rates of atmospheric deposition of sulfur have declined, leading to more deficiencies being …

Challenges And Applications Of Fine-Grained Temporal Action Understanding: Modeling Temporal Granularity And Data Efficiency, Halil I. Helvaci Jan 2026

Challenges And Applications Of Fine-Grained Temporal Action Understanding: Modeling Temporal Granularity And Data Efficiency, Halil I. Helvaci

Theses and Dissertations--Electrical and Computer Engineering

Fine-grained Temporal Action Segmentation (TAS) has become a cornerstone of video understanding, offering dense frame-level predictions essential for clinical assessment, surgical skill evaluation, and human-computer interaction. While TAS methods have delivered strong results on coarse-grained benchmarks, two fundamental challenges persist: (1) global attention mechanisms dilute boundary information critical for subsecond precision, a phenomenon we term the temporal granularity bottleneck, and (2) dense frame-level annotation remains prohibitively expensive, with most datasets requiring exhaustive labeling of lengthy untrimmed videos. These challenges are particularly pronounced in medical domains, where sub-second primitives define clinical outcomes while expert annotation remains scarce. In this dissertation, we …


Making Sense Of Membership: Organizational Socialization Of African Immigrant Employees In U.S. Workplaces, Ikeola J. Bodunde Jan 2026

Making Sense Of Membership: Organizational Socialization Of African Immigrant Employees In U.S. Workplaces, Ikeola J. Bodunde

Theses and Dissertations--Communication

This dissertation examines how African immigrant employees make sense of organizational socialization in U.S. workplaces. As global mobility reshapes the labor force, nearly one in five U.S. workers is foreign-born, making organizational socialization an increasingly complex communicative process. Classic socialization models assume linear, uniform adjustment, yet international employees often face ambiguity, cultural mismatch, and racialized expectations that complicate early workplace experiences. Guided by sensemaking theory, this study conceptualizes socialization as an ongoing, nonlinear process through which newcomers notice cues, construct interpretations, act on provisional understandings, and revise meanings as contexts shift. Using a qualitative, interpretive design, I conducted semi-structured interviews …
