Portable Multi-Parametric Microscopy For Noninvasive Metabolic And Vascular Imaging Of Orthotopic Tongue Cancer Models In Vivo, Pranto Soumik Saha, Jing Yan, Caigang Zhu

Markey Cancer Center Faculty Publications

Significance: Precise imaging of tumor metabolism with its vascular microenvironment becomes emerging critical for cancer research because increasing evidence shows that the key attribute that allows a tumor to survive therapies is metabolic and vascular reprogramming. However, there are surprisingly few imaging techniques available to provide a systems-level view of tumor metabolism and vasculature in vivo on small animals for cancer discoveries.

Aim: We aim to develop a new multi-parametric microscope that can faithfully recapitulate in vivo metabolic and vascular changes with a wide field of view and microscope-level resolution to advance cancer-related investigations. To maximize the ease and accessibility …

Enhancing Disease Surveillance In Conflict Settings: An Ecological Case Study On Cholera In Sudan At The Intersection Of Environmental And Conflict Drivers, Kinsey Medlin

Public Health Theses

Cholera outbreaks are complex and driven by an interaction of environmental circumstances and conflict-related disruptions, yet few studies have integrated both in the context of conflict regions. This ecological study examines cholera transmission dynamics in Sudan from 2016 to 2025, exploring temporal associations using cross-correlation analysis and applying generalized additive mixed models (GAMMs) to analyze the influence of remotely sensed environmental variables (rainfall, temperature, NDVI, NDWI) and conflict indicators (civilian targeting, political violence, demonstrations) on cholera cases. Weekly cholera surveillance data, combined with satellite-derived environmental variables and conflict event datasets, were modeled across two time periods: pre-conflict (2016-2018) and active …

INTRODUCTION

Evidence points to dysregulated Ca²⁺ in neurons and astrocytes in models of amyloidosis. While most of these data were obtained in vitro or in vivo under anesthesia, less work has investigated these variables in awake ambulating mice.

METHODS

Astrocytic Ca²⁺ fluctuations (GCaMP8f) were imaged concomitantly with vasoreactivity in S1 on a two-photon microscope during rest and ambulation. Single-cell resolution variables were extracted using continuous wavelet transform and traditional ΔF/F measures.

RESULTS

Along with increases in amyloid beta (Aβ) accumulation, we found significant reductions in measures of astrocyte functional connectivity, pairwise correlations, and network synchronicity in older 5×FAD …

Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan M. Thomas, Daniel J. Kelly, Richard N. Funston

Nebraska Beef Cattle Reports

This study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Heifers were artificially inseminated with semen from one of three single-sires or semen from a combination of the same three sires. Pregnancy rates did not significantly differ. Paternity testing suggests sire parentage can be unequal when semen is mixed from multiple sires. In summary, producers can expect similar pregnancy rates using single-sire and multi-sire semen, but progeny may have unequal sire representation.

Impact Of Overwinter Gain On Growth And Reproductive Performance In March-Born Heifers, Josie N. Crouch, J. Travis Mulliniks, Jacki A. Musgrave, Kacie L. Mccarthy

Nebraska Beef Cattle Reports

Summary with Implications

Heifers developed to lower rates of overwinter gain may reduce development costs without growth and reproduction impacted. A 3-year study was conducted to evaluate different overwinter rates of gain on heifer growth rates, reproductive, and economic performance. Heifers were managed together and individually supplemented (January-May) with dried distillers grains to achieve either a low (0.75 lb/d) or high (1.50 lb/d) average daily gain. At breeding, high gain heifers were heavier than low gain heifers. Average daily gain and body condition score were similar between treatments. Overwinter treatment did not impact attainment of puberty, pregnancy rates, or the …

Impact Of Pre- And Post-Breeding Supplementation On Performance Of May-Born Heifers, Josie N. Crouch, J. Travis Mulliniks, Jacki A. Musgrave, Kacie L. Mccarthy

Nebraska Beef Cattle Reports

Summary with Implications This 3-year study compared growth, reproductive performance, and economics of May-born yearling heifers that either received 2.00 lb/ heifer/ per d of a dried distillers grain supplement from pre-breeding (July) through breeding (August) or no supplement. Supplementation was offered approximately 24 days before breeding, averaging 55 days total. Heifer body weight was unaffected by supplementation. Supplementation increased average daily gain until pregnancy diagnosis, but no differences were noted after pregnancy diagnosis. Providing dried distillers grain increased the percentage of heifers that were cycling before breeding; however, no differences in pregnancy rates, percent that gave birth in the …

Interaction Of Backgrounding System And Implant Use On Growing Calf Performance, Sydney T. Vanderhoff, Braden C. Troyer, Rebecca L. Mcdermott, Mitchell M. Norman, Brandon L. Nuttelman, Galen E. Erickson, Mary E. Drewnoski, James C. Macdonald

Nebraska Beef Cattle Reports

Summary with Implications

A two-year study utilized 480 weaned steers each year targeted to gain either 1 or 2 lb/d during the winter followed by ad libitum forage intake during the summer to determine the effects of winter rate of gain and implant strategy during the winter backgrounding and summer phases on steer performance, forage intake, and compensatory gain. During the winter, steers received a Revalor-G or no implant. In the summer, steers either received a Revalor-IS or no implant. The use of Revalor-G and increased rate of gain during the winter backgrounding phase had additive effects to increase animal …

Nebraska Beef Cattle Reports

Summary with Implications

A finishing trial was conducted to evaluate the effects of varying dietary inclusion of modified distillers grains plus solubles compared to a constant inclusion throughout the entire feeding period on finishing cattle performance. Treatments were arranged as a 2 × 2 + 1 factorial with two inclusions of modified distillers grains plus solubles (10% and 25%) that were constant or varying in dietary inclusion, and a corn control (0% modified distillers grains plus solubles). Increasing the inclusion of distillers grains from 0 to 25% increased both DMI and ADG when fed at a constant inclusion of 10 …

Impact Of Full-Fat Wet Distillers Grains Inclusion In Steam-Flaked Corn Based Finishing Diets, Gatlin Hissong, Bill Dicke, Doug Smith, Andrea Watson, Galen E. Erickson

Nebraska Beef Cattle Reports

Summary with Implications

Steam-flaked corn and distillers grains are common feed ingredients in finishing rations, but the interaction between the two is not well understood. A finishing trial at a commercial feedlot using 700 calf-fed heifers was conducted to evaluate cattle performance when fed 18 or 30% (dry matter basis) full-fat wet distillers grains plus solubles in steam-flaked corn based diets with 8% roughage (hay + corn silage). No effects on cattle performance were observed due to distillers grains inclusion in the diet. Final body weight, dry matter intake, average daily gain, feed conversion, and hot carcass weight were not …

Effect Of Feeding Palm Oil On Finishing Cattle Performance, Carcass Characteristics, And Methane Production, Anna M. Kobza, Rebecca L. Mcdermott, Mitchell C. Norman, Joshua R. Benton, Long Zou, James C. Macdonald, Galen E. Erickson

Nebraska Beef Cattle Reports

Summary with Implications

Increased demand for biofuel production has increased demand and price of commonly fed supplemental fat sources in beef operations. This finishing study evaluated the effect of feeding palm oil products on performance, carcass characteristics and methane production of feedlot finishing steers. Dietary treatments were feeding no supplemental fat or feeding one of the following fat sources at 4% of diet dry matter: whole palm oil, palm stearin, palm olein, or corn oil. Feeding supplemental fat, regardless of source, increased final body weight, average daily gain, and hot carcass weight. Feeding supplemental fat had no effect on dry …

Effect Of Using Whole Soybeans, Roasted Soybeans, Or Soybean Meal In Finishing Cattle Diets, Melissa K. Bausch, James C. Macdonald, Galen E. Erickson, Pablo L. Loza

Nebraska Beef Cattle Reports

Summary with Implications

A feedlot study compared the effect of using whole or roasted soybeans at two inclusion rates (12% and 16% of diet dry matter), soybean meal, distillers grains, or a dry-rolled corn with urea control in finishing cattle diets. Steers fed the diet with the 16% inclusion of roasted soybeans had better average daily gain, feed conversion, and hot carcass weight. All other diets resulted in similar performance to the dry-rolled corn and distillers grains treatments. Roasted soybeans fed at a 16% inclusion improved F:G over the 12% roasted soybeans as compared to the whole soybeans which were …

Decentral Intelligence Agency: The Law And Autonomous Artificial Intelligence, Dr. Andrew W. Torrance , Ph. D., Dr. Bill Tomlinson , Ph.D.

Touro Law Review

Artificial intelligence (“AI”) is rapidly gaining autonomy across a range of domains, such as business, education, social relationships, and warfare. This article examines the legal and policy implications of autonomous AI agents, a rapidly evolving technology that challenges existing regulatory frameworks. Drawing from tort, agency, property, contract, privacy, human rights, and constitutional law, we propose a comprehensive approach to govern these increasingly independent entities. Our analysis begins with a historical perspective, tracing both the evolution of autonomous computational systems and of legal responses to such technologies. We then conduct a comparative study of AI governance across jurisdictions, highlighting regulatory gaps …

Article Iii Standing For Cercla Private Cost Recovery Actions: How The Test's Strained Logic Belies Its Authority, Jonathan M. Palacios

Fordham Environmental Law Review

This Note examines how Article III standing doctrine applies to

private plaintiffs’ cost recovery actions under § 107(a)(4)(B) of the

Comprehensive Environmental Response, Compensation, and

Liability Act. A review of judicial decisions reveals inconsistencies

in the analysis of injury in fact and traceability, and suggests that

current Article III standing doctrine is misaligned with its purported

objectives. In response, this Note proposes a structured framework

for assessing injury in fact and a refined approach to analyzing

traceability that distinguishes between different forms of causal

uncertainty. These doctrinal adjustments should better align case

outcomes with Article III standing doctrine’s constitutional and …

Cronyism In Creating Chronic Disease—A Path To Food Justice, Martha Leonard

St. Thomas Law Review

Central to this discussion is a quote often attributed to the ancient Greek physician Hippocrates: “Let food be thy medicine, and medicine be thy food.” Today, physicians recognize the crucial role of diet in maintaining good health and preventing chronic disease, but U.S. laws fail to reflect this understanding. The health field has seen significant progress in scientific research on pathology; however, nutritional research presents a challenging and contradictory landscape. Corporate influence in scientific research leads to a lack of consensus on the most optimal diet for promoting general health, presenting a challenge for policymaking. The dark reality is that …
