Comparative Analysis Of Probiotic Viability In Alcoholic And Non-Alcoholic Kombucha, Isabella N. Cerrone, Brooke Pirkle, Danielle Williamson, Gianna Vendrell, Chloe Kraft

Humboldt Journal of Microbiology

Kombucha is a fermented tea beverage valued for its probiotic and antimicrobial properties that arise from complex molecular interactions between yeast, acetic acid bacteria (AAB), lactic acid bacteria (LAB), and metabolic byproducts of fermentation. With the rising demand for non-alcoholic versions of traditionally alcoholic kombucha beverages, ethanol reduction methods have become common, though their impact on probiotic viability and antimicrobial properties remains poorly understood. This study investigates the effects of ethanol removal on kombucha’s functional properties, including probiotic survival, antimicrobial activity, and organic acid composition (pH). We compared alcoholic and non-alcoholic versions of JuneShine kombucha across five flavors. Probiotic viability …

Impact Of Physiological And Environmental Variation On The Behavioral Response Of The Two Biological Control Agents Of The Emerald Ash Borer To Host-Associated Odors, Vanshika Jindal

LSU Master's Theses

Emerald ash borer (Agrilus planipennis Fairmaire; EAB) is an invasive pest that threatens ash trees (Fraxinus spp.) throughout North America and Europe. Since its introduction to North America, EAB has killed hundreds of millions of trees, resulting in severe ecological and economic damage exceeding 10 billion US dollars. Classical biological control involves the introduction of natural enemies from the native range of pests to manage their populations. Specialist parasitoid wasps have been released to reduce the populations of EAB. Detection and response to long-range attractants associated with EAB is critical for the location and parasitism by classical biological …

The Functional Efficiency Of Healing Gardens Elements And Its Impact On The Functional Aspect Of Hospitals, Menna Allah Hesham Mohammed, Heba Mohamed Abdou

Mansoura Engineering Journal

Communication with nature has a positive effect on human health and well-being in different civilizations all time. But technological development caused the production of purely functional buildings that are far from communicating with nature, although some buildings contain gardens to achieve communication with nature, their elements are poor. Therefore, healing gardens are considered one of the main elements to raise the efficiency of the functional performance of the health building because they contain the resting places and healing departments. Therefore, this study focuses on determining the functional criteria for the elements of the garden that must be considered when designing …

Preclinical Fluorescence-Guided Imaging Leveraging Surrounding Sentinel Tumor Microenvironment Identifies High-Risk Premalignant Pancreatic Lesions, Shilpa Sharma, Xiaoxia Wen, Jianbo Wang, Beibei Huang, Denise A Hernandez, Zhiwen Liu, Aiko Yamaguchi, Dimitra K Georgiou, Ryan P Coll, H Charles Manning

Faculty, Staff and Student Publications

Purpose: Because surgery is the only potential cure for pancreatic cancer, high-risk premalignant pancreatic lesions often evade detection by palpation or white-light visualization, increasing the risk of recurrence. We asked whether near-infrared fluorescence imaging of tumor-associated inflammation could identify high-risk premalignant lesions, leveraging the tumor microenvironment as a sentinel of local disease and, thus, enhance surgery outcomes.

Experimental design: Fluorescence-guided surgery was performed on genetically engineered mice [Ptf1a-Cre; LSL-KrasG12D/+; Smad4flox/flox (KSC)] at discrete stages of disease progression, histologically confirmed high-risk, premalignant lesions in postnatal mice to locally advanced pancreatic tumors in adults, using the imaging agent V-1520, a translocator protein …

Triple-negative breast cancer (TNBC) that fails to respond to neoadjuvant chemotherapy (NACT) can be lethal. Developing effective strategies to eradicate chemoresistant disease requires experimental models that recapitulate the heterogeneity characteristic of TNBC. To that end, we established a biobank of 92 orthotopic patient-derived xenograft (PDX) models of TNBC from the tumors of 75 patients enrolled in the ARTEMIS clinical trial (NCT02276443), including 12 longitudinal sets generated from serial patient biopsies collected throughout NACT treatment and from metastatic disease. Models were established from both chemosensitive and chemoresistant tumors, and nearly 30% of the PDX models were capable of metastasizing …

College of Life Sciences Faculty Papers

Understanding the role of humans as 'ecosystem engineers' requires a deep-time perspective rooted in evolutionary history and the fossil record. However, no conceptual framework exists for studying the rise of ecosystem engineering in deep time, requiring us to consider effects that fall outside the scope of traditional definitions. Here, we present a new framework applicable to both modern and ancient engineering-type effects. We propose a new term - 'Earth system engineering' - to describe biological processes that alter the structure and function of planetary spheres, and which combines core tenets of ecosystem engineering, niche construction, and legacy effects. We illustrate …

Multilevel Selection In The Margins: A Review Of Its Representation In Undergraduate Biology Textbooks, C. A. Greene, S. J. Mcpeek, L. Mitchem, A. B. Clark, Vincent A. Formica

Biology Faculty Works

Multilevel selection (MLS) is a foundational framework that expands the concept of natural selection beyond the traditional focus on individuals or genes to larger units, like groups. Despite strong empirical support and applications in a broad range of biological fields, MLS, often referred to as group selection, has a controversial history, which has impeded its wide use and led to incorrect inferences on the sources and strength of selection. Here, we explore how MLS is currently presented to undergraduate biology students by analyzing the content of nine commonly used Evolutionary Biology and Animal Behavior textbooks. We ask whether and how …

Accurate monitoring is vital for optimising hydrolysis efficiency, minimising nonspecific proteolysis, ensuring consistent yields, and preserving peptide biofunctionality. While analytical and computational tools are well-established for non-fungal systems, their adaptation to fungal proteases remains exploratory, with no comprehensive evaluation addressing the unique challenges in this field. This review synthesises current knowledge, identifies methodological gaps, and outlines future directions for developing fungi-specific analytical pipelines and computational frameworks for BP discovery. It explores fungal protease families, their roles in intracellular peptide processing, and fungal survival strategies. …

Substituted Piperidines As (Alpha4)3(Beta2)2 Nicotinic Acetylcholine Receptor Positive Allosteric Modulators: In Vitro Pharmacology, Nataly Sanchez, Josue Gaona, Wilder Felix, Nathalia Menegasso, Brisa Cea, Ganesh Thakur, Ayman K. Hamouda

School of Medicine Student Publications and Presentations

Nicotinic acetylcholine receptors (nAChRs) play a crucial role in the pathogenesis of neurodegenerative diseases such as Parkinsonʼs disease (PD). In PD, degeneration of dopaminergic and cholinergic neurons impairs neurotransmitter release, leading to cognitive and motor dysfunction. Current treatments provide only symptomatic relief, highlighting the need for novel therapeutic strategies. The (α4)₃(β2)₂ subtype of nAChRs is expressed on affected neurons, making it a promising druggable target for enhancing neurotransmitter release and providing neuroprotection. To explore the therapeutic potential of positive allosteric modulators (PAMs) of (α4)₃(β2)₂ nAChRs, we evaluated chemical derivatives of CMPI [3-(2-chlorophenyl)-5-(5-methyl-1-(piperidin-4-yl)-1H-pyrazol-4-yl)isoxazole]. We used two-electrode voltage-clamp recordings from Xenopus laevis …

Chambers

Faculty Journal Articles

Cecropins are a class of antimicrobial peptides (AMPs) expressed by insects that have broad-spectrum antimicrobial activity and low cytotoxicity. However, cecropins are also long (40–45 amino acids) peptides, making their adaptation for therapeutic use challenging. Here, we present a series of 16 amino acid-long peptides derived from cecropin B from Drosophila melanogaster. The native truncated peptide is cationic and expected to form an amphipathic α-helix, but does not have antimicrobial activity. The incorporation of two Trp residues, depending on the position in the peptide backbone, results in antibacterial activity compa-rable to that of full-length cecropin B against the gram-negative bacteria …
