Journal of the Saudi Heart Association

Background: Acute coronary syndrome (ACS) in young adults is uncommon. The case of a 34-year-old male, post mechanical mitral valve replacement (MVR), who developed anterior ST-elevation myocardial infarction (STEMI) despite therapeutic anticoagulation (INR 3.17), shortly after the initiation of diclofenac, highlights an important clinical scenario.

Case Presentation: The patient presented with atypical upper back pain and was diagnosed with anterior STEMI. Coronary angiography revealed a 100% thrombotic occlusion in the mid left anterior descending (LAD) artery. Percutaneous transluminal coronary angioplasty (PTCA) was successfully performed. Importantly, the patient had no history of hypercoagulable states or atherosclerosis and had been compliant with …

Optimized Resnet-18 Architecture For Multi-Class Oral Diseases Classification, Ahmed Ahmed

Karbala International Journal of Modern Science

In recent years, the classification of oral diseases has gained significant attention due to its influence on public health and the necessity for early and accurate diagnosis. Traditional diagnosis depends on manual clinical assessment, which can be slow and subjective. An optimized and subsequently quantized model is required to provide a faster and more consistent diagnostic support tool. This paper proposes an optimized ResNet-18 architecture for the classification of six oral diseases. The optimization process is based on removing the Rectified Linear Unit (ReLU), Batch Normalization (BN), and convolutional layers from the base ResNet-18 blocks that contain 128 filters. This …

Sperm-Associated Antigen 6 (Spag6) As A Potential Marker Of Sperm Function In Diagnosing Male Infertility, Ibtisam A. Al-Ali,, Kawkab A. Alsaadi

Karbala International Journal of Modern Science

Background: While male infertility has become a significant global health concern, conventional analysis of semen has not made progress in the detection of contraindicated molecular biomarkers, such as sperm-associated antigen 6 (SPAG6), which is a protein involved in axonemal structure and flagellar motility.

Hypothesis: Expression of SPAG6 correlates with sperm motility and structural integrity. This means that its dysregulation may serve as a molecular indicator of impaired sperm performance.

Methods: A comprehensive review of recent studies was conducted with a focus on SPAG6’s molecular characteristics, expression patterns in normal versus abnormal spermatozoa, and the role it plays in motility-related …

Rethinking Geoengineering Governance Utilizing The Playing God Argument: Considerations Of Knowledge, Control, And Benevolence, Julian Dreiman, Brian Patrick Green

Staff Publications and Research

Because greenhouse gas emissions continue to grow, it is increasingly challenging to limit global warming to 1.5 or 2.0 degrees Celsius. As such, there is a growing debate on whether or not to deploy geoengineering to reduce warming. Geoengineering is controversial, and many arguments have been raised against it, including the “playing God” critique. When understood through the philosopher Moti Mizrahi’s reinterpretation, the playing God critique does not eliminate the possibility of using geoengineering, but rather informs how its governance can be improved. We use Mizrahi’s interpretation of the playing God critique to claim that the existing governance literature lacks …

Cmsi Note 18: Flooding The Zone: The Use Of Civilian Landing Craft (Lcts) In Pla Amphibious Operations, Thomas Shugart, J. Michael Dahm

CMSI Notes

In July and August 2025, China’s People’s Liberation Army (PLA) employed a unique type of civilian deck cargo ship known as a Landing Craft Tank (LCT) to transport military vehicles directly to shore as part of an amphibious landing exercise. While civilian deck cargo ships of this type have been observed in previous PLA over-the-shore logistics exercises, they had only been used to transport vehicles and equipment from port-to-port—simulating the transport of forces into a captured port—not directly to an unimproved beachhead. If the PLA develops the ability to coordinate and employ significant numbers of civilian LCTs to transport forces …

A Policy Reversal As Structural Break: A Lesson From China’S Land Lease Financing For Infrastructure, Yilin Hou, Lin Li, Lei Shao

Center for Policy Research

Land-based revenues as a fiscal instrument to finance infrastructure tie public investment to real estate markets, where demand fluctuations cause fiscal consequences. This paper takes policy reversals as structural breaks and examines their impacts on infrastructure investment. We dissect China’s 2016 policy reversal that disallowed developers to finance land purchase with debt, causing sharp declines in local government land revenues, slashing their fiscal base for infrastructure investment. Using prefecture-level panel data and continuous difference-in-differences identification, we estimate the reversal reduced land-lease revenues by 55%. Two-stage least squares estimates suggest a 10% land-revenue decline translates into 6.6% investment reduction. Decomposing the …

The Vascular Density/Angiogenesis Marker Cd31/Pecam1 Does Not Correlate With Overall Survival In Neuroendocrine Tumors, Nicholas J. Skill, Kenneth Avanzino, Yvette Bren-Mattison, J. Philip Boudreaux, Ramcharan Thiagarajan, Mary Maluccio

School of Medicine Faculty Publications

Abstract: Neuroendocrine neoplasms (NENs) are rare cancers. CD31/PECAM1 is an adhesion molecule that modulates endothelial cell-to-cell contact. Increased CD31 expression is a marker for tumor growth, and cancer aggressiveness. The purpose of this study was to better understand the prognostic value of CD31 expression in primary and metastatic NEN tumors in terms of correlations with overall survival and pathological metrics, tumor grade, and tumor primary/metastatic location. As NENs are highly vascular tumors, the hypothesis is that CD31 staining is an important prognostic biomarker and target. This is based on prior correlations between CD31 staining and 3-year recurrence-free survival in pancreas …

Banking On Jarkesy, Jacob Cunningham, Todd Phillips

Duke Law Journal Online

The 150-year-old bank regulatory system is under threat. Following the Supreme Court’s landmark decision in Jarkesy, bankers have filed numerous lawsuits challenging the ability of the federal bank regulatory agencies to adjudicate cases in non-Article III tribunals. But unlike the agencies tasked with enforcing the securities, antitrust, and consumer protection laws, the banking regulators lack statutory authority to file cases in federal court. A decision invalidating their in-house adjudicative authority strips of them of any forum in which to file enforcement actions.

This essay argues that these lawsuits should fail. Because the Seventh Amendment jury trial right exempts “public rights,” …

Read My Lips: No New Constructs! Construct Proliferation As A Threat To The Future Of I-O Psychology, Nathan A. Bowling, Valerie I. Sessa, Jonathan A. Shaffer, George C. Banks

Department of Psychology Faculty Scholarship and Creative Works

Industrial and organizational (I-O) psychology recognizes dozens of different constructs, including several individual differences, environmental variables, job attitudes, and work-related behaviors. It is, of course, necessary to retain a variety of constructs in order to adequately capture the complexities, subtleties, and diversity of work-related phenomena. But do the many constructs recognized by I-O psychologists all serve a useful purpose? Or has our field been too eager to welcome redundant, unnecessary constructs into the fold? And if I-O psychology has embraced too many unnecessary constructs, then what—if anything—should we do about it? In the current focal article, we first discuss when …
