Conflating Disease, Morality, And Sex: Regulating Military Fitness In The War Years, Hanna Ranis Dec 2025

Conflating Disease, Morality, And Sex: Regulating Military Fitness In The War Years, Hanna Ranis

Bates College Journal of Political Studies

The United States military worried about the impact of venereal diseases on the ability of soldiers to fight in both World War 1 and 2. The war years thus resulted in an increase in regulations that sought to curb the spread of venereal diseases. Much of this regulatory shift has focused on how police targeted women who were suspected of spreading venereal diseases to American soldiers. Women were profiled as promiscuous and possible sex workers, with the lines between the two categories becoming increasingly blurred. Policing was viewed as a public health regulatory mechanism that needed to be carried out …

Journal of Food and Drug Analysis

Leydig cells are anatomically located in the testicular interstitial tissue, and their main function is to produce and secrete testosterone and indirectly support spermatogenesis. We previously reported that the combination treatment of cordycepin and radiation can effectively induce Leydig tumor cell apoptosis through cell cycle arrest, caspase activation, endoplasmic reticulum (ER) stress, reactive oxygen species (ROS) accumulation, and DNA damage. However, there is still a lack of scientific evidence for the susceptibility of normal Leydig cells to the combination treatment. In the present study, mouse TM3 Leydig progenitor cells were used as a model to evaluate the effects and mechanisms …

Targeting Chemical Carcinogenesis: Α-Pinene And D-Limonene As Chemopreventive Agents Against Nnk/ Tcdd- And Urethane-Induced Lung Tumorigenesis, Kuo-Ching Huang, Vui-Hyen Chew, Yu-Ying Chen, Huey-Jen Su, Hao-Ting Chang, Rong‑Jane Chen, Ying‑Jan Wang

Journal of Food and Drug Analysis

Lung cancer is the leading cause of cancer-related deaths worldwide, driven by carcinogens such as tobacco-derived nitrosamines, dioxins, and urethane. This study evaluated the chemopreventive effects of two monoterpenes, α-pinene and D-limonene, using NNK/TCDD- and urethane-induced lung tumor models and A549 lung cancer cells. Both compounds significantly reduce tumor number and size, with enhanced effects when combined. Mechanistic studies revealed suppression of PRC1, β-catenin, and c-Myc, alongside activation of p53, Bax, and caspase-3, indicating inhibition of the PRC1—Wnt/β-catenin pathway and induction of apoptosis. These findings suggest α-pinene and D-limonene as safe, promising agents for lung cancer chemoprevention.

Intrinsic Stability Of Controlled Systems Via Gershgorin-Type Estimates, David Friedbaum Dec 2025

Intrinsic Stability Of Controlled Systems Via Gershgorin-Type Estimates, David Friedbaum

Theses and Dissertations

Time delays are an inherent feature of real-world dynamical systems, arising whenever information, matter, or energy requires non-negligible time to propagate. Even small delays can destabilize systems that are otherwise well behaved, yet most standard control designs--such as PID or LQR--do not explicitly account for them and may fail when delays are present. This thesis investigates the stability of controlled dynamical systems subject to arbitrary time delays and develops new tools to determine when such systems remain stable. Our approach builds on the notion of intrinsic stability, a strong form of global stability introduced by Webb and Bunimovich, which guaranties …

PURPOSE: Clinical risk grouping based on PSA, tumor grade, and disease extent guides treatment intensity for localized prostate cancer. However, many patients with intermediate- or high-risk disease treated with external beam radiotherapy (EBRT) and androgen deprivation therapy (ADT) still develop biochemical recurrence (BCR). Early identification of patients at high risk for BCR could enable personalized treatment strategies.

EXPERIMENTAL DESIGN: We prospectively enrolled 29 patients with intermediate- or high-risk prostate cancer undergoing EBRT and ADT. Pretreatment biopsies (n = 60) underwent whole-transcriptome microarray and whole-exome sequencing. Patients received multiparametric MRI at baseline and 6 months after treatment, with a median follow-up …
