Journal of the South Carolina Academy of Science

Human Papilloma Virus (HPV) is the most common sexually transmitted infection (STI) in the United States, infecting up to 75% of sexually active individuals, with a prevalence rising significantly around age nineteen for oral and genital infections. Because the virus infects epithelial cells and is transmitted primarily through skin-to-skin contact, it is found mainly in the cervix, oral cavity, and on/within ones’ skin. While most of the 200+ HPV subtypes are benign and tend to self-clear within six months to two years, twelve of these strains are classified as high-risk oncogenic strains that drive malignant progression. Furthermore, HPV is linked …

The Structure And Regulatory Mechanism Of The Emrb Rna Motif In Lactobacillus Acidophilus, Isabella J. Mezzenga, Brian M. Lee

Journal of the South Carolina Academy of Science

Major facilitator superfamily (MFS) transporters aid bacteria in expelling toxic compounds such as antibiotics, bile acids, and other substances. Previous bioinformatic studies identified the emrB motif as a potential regulatory RNA element. In Lactobacillus, this RNA motif is generally found in the intergenic region upstream of an MFS transporter gene with homology to the emrB gene from Escherichia coli. Secondary structure predictions of the intergenic region were used to define the structural features of this RNA motif. The emrB motif comprises two hairpins, though inclusion of neighboring regions is predicted to stabilize alternative secondary structures. A potential rho independent terminator …

Dengue: A Global And Emerging Health Challenge, Christopher Artigas

Lynchburg Journal of Medical Science

Dengue virus, a rapidly expanding tropical arbovirus with four distinct serotypes, poses a growing global public health threat—particularly in regions where healthcare systems are ill-equipped to diagnose, treat, and manage its severe manifestations. Transmitted primarily by Aedes mosquitoes, dengue typically manifests as an acute febrile illness characterized by severe myalgias ("bone-breaking fever"), arthralgias, gastrointestinal distress, and hemorrhagic tendencies. In severe cases, the infection can progress to life-threatening dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Because definitive antiviral therapeutics remain in development, supportive clinical care, with a critical focus on timely intravenous fluid resuscitation, is the cornerstone of management. …

Beyond The Neocortex: Pallial Routes To The Edge Of Sentience, Oryan Zacks

Animal Sentience

In The Edge of Sentience, the sentience candidacy of fishes and reptiles is strengthened if one accepts midbrain-centric theories of human consciousness. In this commentary I attempt to untether the two positions. I suggest that we need not look for a one-to-one match between the neocortex and a single pallial structure outside of mammals. Instead, a sufficient similarity might exist between the mammalian neocortex and the combination of pallium and midbrain in fishes and reptiles. Adopting an evolutionary perspective in the study of vertebrate brains could point to new investigation priorities in human and animal research.

How Inclusive Is The Brainstem Rule? Partiality Beyond Consensus, Charlotte Gauvry, Nurida Boddenberg

Animal Sentience

In his 2024 book, Jonathan Birch builds a precautionary framework for the borderlines of sentience, one that is meant to guide both theoretical reflection and practical action. One of the book’s great merits is its bottom-up approach, which presents itself as theoretically neutral regarding the (neuro-)physiological criteria required for sentience. Yet the singular place granted to midbrain-centric views (e.g., Merker, 2007; Panksepp, 2011; Solms, 2021) and to what Birch calls the “brainstem rule” (Chapter 11) raises questions. What justifies granting it such a central role? What are its practical and theoretical consequences?

Autofield-Poa: A Hybrid Automl–Metaheuristic Framework For Automated Feature Selection In Recommender Systems, Mohammed Dheyaaldeen Taha, Waleed Kareem Ahmed, Rana Saad Mohammed, Zied O. Ahmed

Karbala International Journal of Modern Science

The problem of automated feature selection is one of the most important aspects of modern recommender systems, as overestimating the number of feature fields used, which can increase model complexity, inference latency, and performance degradation due to redundancy and noise. Although differentiable Automated Machine Learning (AutoML) based feature selection methods, including AutoField, are effective, they remain susceptible to initialization and local optima. Conversely, population-based metaheuristic algorithms are effective at global exploration, but are often inefficient in high-dimensional discrete spaces when randomly initialized. This paper presents AutoField-POA, a hybrid AutoML-metaheuristic framework that combines a differentiable controller with the Pelican Optimization Algorithm …
