Enhancement Of Phenolic, Flavonoid, And Biological Activi-Ties In Fermented Pea (Pisum Sativum) Extracts Via Frac-Tionation, Anastasia Fitria Devi, Euis Filailla, Setyani Budiari, Hani Mulyani, Nina Artanti

Karbala International Journal of Modern Science

In this study, peas were fermented for 24 h using either Rhizopus oligosporus or Aspergillus oryzae. The resulting fermented peas, along with unfermented peas, were extracted using either methanol or water. The methanol extracts showed greater improvements following fermentation compared to the water extracts, as shown by the IC₅₀ values, which progressed from >500 to ≤200 µg/mL, as determined via the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) method. Consequently, further fractionations focused on the methanol extracts of the fermented peas. Six bands were resolved on thin-layer chromatography plates for each extract. Their positions demonstrated significant effects (p < 0.05) on bioactivity. The bottom band (i.e., Band 1) exhibited approximately 70% inhibition, as determined via the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and 35% inhibition according to the ABTS method, while the other bands displayed lower to negligible inhibition. Band 5 displayed 85–97% cytotoxicity, while Band 1 did not show any cytotoxicity. The total phenolic content (TPC) of Band 1 and the total flavonoid content (TFC) of Band 6 increased 4.4- and 8.9-fold, respectively, compared to those of the unfractionated extracts. Furthermore, a correlation analysis revealed a strong correlation between TFC and the three observed bioactivities. The different cultures significantly (p < 0.05) affected the antioxidant activity of either the fermented pea extracts or the resulting bands, as determined via the DPPH method. These results indicated that fermentation enhanced the antioxidant activity of peas. Subsequent fractionations separated and concentrated compounds from the fermented peas, improving the bioactivities, TPC, and TFC of the resulting fractions.

Synthesis Of Gold Nanoparticles Using Hordeum Vulgare Leaf Extract And Their Antibacterial Activity, Mohamed M. Sehree, Shakir Ghazi Gergees, Pakhshan A. Hassan

Karbala International Journal of Modern Science

Plant extracts and gold nanoparticles are promising alternatives for combating antibiotic resistance in light of the increasing bacterial resistance. Leaf extract of barley was used to synthesize gold nanoparticles (AuNPs). Barley gold nanoparticles (BL-AuNPs) were produced by adjusting some reaction parameters. These BL-AuNPs were characterized through employing the UV-visible spectroscopy technique, the scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), and energy dispersive X-ray spectroscopy (EDX). BL-AuNPs were tested for antibacterial efficacy against two strains of Gram-negative bacteria, clinically isolated and considered as multidrug-resistant pathogens, Acinetobacter baumannii and Salmonella typhi. The antimicrobial efficiency of the compounds was evaluated …

The Impact Of Microplastics On Water Quality, Heavy Metals, And Health Risks In Bioflocbased Tilapia Farming Systems, Dian Rizky Afriani, Deswati Deswati, Rahmiana Zein, Putri Ramadhani

Karbala International Journal of Modern Science

Along with microplastics, pollution of heavy metals, including iron (Fe), zinc (Zn), and copper (Cu), in freshwater ecosystems poses a serious environmental threat that can adversely affect human health. This study investigates the use of biofloc technology to reduce microplastic and heavy metal contamination while improving water quality. By utilizing microbial aggregates that capture microplastic and heavy metal particles through flocculation and biosorption processes, four experimental treatments were applied, i.e.: A (without biofloc and microplastics); B (with biofloc, without microplastics); C (with biofloc and low-density polyethylene microplastics); and D (with biofloc and high-density polyethylene microplastics). The results indicate that fish …

Evaluating Potential Changes From Nitrogen To Phosphorus Nutrient Limitation Of Phytoplankton Growth In North Inlet Estuary, Catherine Schlenker, James L. Pinckney

Faculty Publications

In marine systems, molar ratios of the biolimiting inorganic nutrients, nitrogen (N) and phosphorus (P), are assumed to follow the “Redfield ratio” (N:P = 16:1), which is often used to infer nutrient limitation of phytoplankton biomass. Traditionally, estuaries are considered N-limited (N:P <  16) but with higher coastal N-loading, reports of P-limitation (N:P > 16) have increased. In recent decades, nutrient loading in North Inlet Estuary (NIE) has changed such that dissolved inorganic nitrogen (DIN):dissolved inorganic phosphorus (DIP) ratios increased from ca. 7 to 20 (2002–2021). This suggests that primary production in NIE may be transitioning from N-limitation to NP co-limitation or primary P-limitation. Due to high N:P ratios, we hypothesized that …

The 2 Sigma Genus Concept In Mammalogy: Lessons From Lasiurus, Amy B. Baird, Janet K. Braun, Mark D. Engstrom, Burton K. Lim, Michael A. Mares, Luis A. Ruedas, John C. Patton, John W. Bickham

Biology Faculty Publications and Presentations

Species concepts are well established and apply across diverse groups of organisms; however, there is no consensus on what defines higher taxonomic groups. The genus rank is important to taxonomists because it comprises part of the scientific name of an organism. A consistent and biologically meaningful method for determining generic status is needed for taxonomic stability and utility. Lasiurine bats are a group for which there is disagreement on how many genera to recognize. Some authors argue for splitting this group into three genera based on morphology, genetic divergence, and time of divergence; others argue that a single genus should …

Modulation Of Pulmonary Epithelial Paracellular Permeability By Pneumolysin From Streptococcus Pneumoniae, Alexandra S. Tamayo Moreira

Biology Theses

Pneumolysin (PLY), a key virulence factor of Streptococcus pneumoniae (S. pneumoniae), disrupts airway epithelial barriers, yet its cellular and molecular mechanisms remain poorly understood. We aim to elucidate recombinant pneumolysin (rPLY)’s effects on Calu-3 bronchial epithelial barrier integrity and underlying pathways. This study investigates the effects of non-lytic and lytic PLY concentrations (5, 15, 30 µg/mL) to test the hypothesis that PLY increases epithelial paracellular permeability by affecting the anatomy and physiology of epithelial tight junctions. To address the hypothesis that PLY increases paracellular permeability through disruption of tight junction integrity in Calu-3 cells in a time- and dose-dependent …

Using Stomach Content Analysis To Determine The Trophic Ecology Of Omosudis Lowii, A Deep-Sea Predator In The Gulf Of Mexico, Claire De Noyo

USF Tampa Graduate Theses and Dissertations

Little is known about the feeding dynamics of deep-sea communities, despite their significant ecological importance. Deep-pelagic communities contribute to marine biodiversity and ecosystem stability while directly offsetting climate change via carbon sequestration. Omosudis lowii is an understudied, deep-sea fish found in temperate and tropical waters worldwide, including the Gulf of Mexico. Omosudis lowii have large jaws and distensible stomachs, allowing them to capture prey items larger than their body size. The present seminal study used stomach content analysis to quantitatively describe the O. lowii trophic ecology, providing baseline data regarding diet composition, feeding selectivity, and factors that impact prey selection. …

Branching Corals Modulate Their Hydrodynamic Environment, Enhancing Capture Rates Of Evasive Prey, Kelsey Daniels

USF Tampa Graduate Theses and Dissertations

Reef-building corals obtain nutrients through two primary means: autotrophy (via mutualism with photosynthetic zooxanthellae) and heterotrophy (via feeding). The latter form of resource acquisition is understudied and many aspects of predator-prey interactions between coral and naturally occurring prey species remain unexplored. In this thesis, I elucidate the role of branching coral morphology in shaping the colony’s local hydrodynamic environment and describe how this environment impacts prey capture, particularly among evasive and hydrodynamically sensitive, but highly abundant prey such as copepods. I used acrylic cylinders of three sizes in aquaria to model the structure of coral branches across the range of …

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There are numerous ways to communicate science and assess the effectiveness of that communication. One approach focuses on increasing awareness, enjoyment, interest, opinion, and/or understanding of science. For this study, we created an informal learning experience for youth to communicate the science of animals in Nebraska. We developed Cool Critters, a weeklong summer camp for elementary school-aged students, to increase participants' enjoyment, interest, and opinion of Nebraska animals. In 2023, Cool Critters was led in three educational settings in central Nebraska and reached sixty-six participants. Surveys were used to determine the camp's success in effective science communication and whether …

Beyond Diversity Initiatives: Building A Community Of Care In Scientific Societies, Richelle L. Tanner, Kathryn Wilsterman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

"In this Professional Biologist article, we present one such reframing that centers individualized care through structural changes. We argue that psychological and sociological motivations of belonging and social capital in the academy are funda- mental challenges contributing to the cultural problems within STEM fields and are particularly present within professional scientific societies. In support of this argument, we present survey- based data alongside significant literature from the humanities. In this reframing supported by existing organizational culture literature and our survey results, we suggest that scientific societies are uniquely positioned to promote significant cultural change within STEM by focusing on building …

Exploiting Genomics To Advance Genetic Gain For Reproductive Traits In Sheep, Mujibur Rahman

ORBioM (Open Research BioSciences Meeting)

Poor reproductive performance has a negative impact on the profitability of sheep production systems with the number of lambs reared highlighted as a key driver of farm profitability. Nevertheless, the genetic improvement of reproductive traits in sheep has been constrained by their low heritability and pleiotropic nature. Understanding the underlying genetic architecture can improve genomic prediction estimates and enhance genetic gain.

This study will utilize large-scale genomic and phenotypic datasets to enhance genetic gain in sheep reproductive traits through four approaches: 1) to determine the effect of inbreeding depression on reproduction, 2) to identify causal variants impacting reproductive performance through …

Evolutionary Conservation Of Wiskott-Aldrich Syndrome Protein In Clarthrin-Mediated Endocytosis, Jonah Friedmann

Lawrence University Honors Projects

Clathrin-mediated endocytosis (CME) is a cellular process for internalizing extracellular materials and recycling parts of the plasma membrane into intracellular vesicles. When a threshold of membrane-bound receptors is met at the cell surface, endocytic proteins organize into a conformation that can invaginate the membrane and separate a vesicle into the cytosol. Our current model for understanding CME has been derived from studies in Saccharomyces cerevisiae. Previous research has led to a model for how Las17, a homolog of Wiskott Aldrich Syndrome Protein (WASP), contributes to CME. WASP proteins are critical actin nucleators involved in multiple processes. In S. cerevisiae, Las17 …

Abstract 2587 Recombinant Expression And Purification Of A. Vinelandii Cown In E. Coli, Julie Takei, Cedric P. Owens, Katie Sanders, Neeraja Gajendran

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The goal of this project is to study the protein CowN in the diazotroph Azotobacter vinelandii (Av) in comparison to CowN in Gluconacetobacter diazotrophicus (Gd). Nitrogenase is an enzyme that catalyzes the reduction of nitrogen gas into ammonia in diazotrophic bacteria. In many diazotrophs, the protein CowN prevents nitrogenase inhibition from the environmental gas carbon monoxide (CO). Previous work studied CowN in the diazotroph G. diazotrophicus. In G. diazotrophicus, CowN binds to nitrogenase and weakens CO binding to its active site. The mechanism of CowN has only been investigated in G. diazotrophicus. Thus, we are interested in determining if CowN's …

The Impact Of Temperature Induced Vertebral Anomalies On C-Start Swimming Performance In Astyanax Mexicanus (Teleostei: Characidae), Kaleigh Arnold

College of Science and Health Theses and Dissertations

This study investigates the impact that temperature-induced vertebral anomalies have on the C-start escape response of Astyanax mexicanus, a model species in evolutionary developmental biology. Employing three temperature treatments to induce varying degrees of skeletal anomalies, we assessed their effects on key swimming performance metrics including, C-start time, the curvature coefficient, head displacement distance, and displacement velocity. Through the use of linear mixed models (LMMs) and generalized linear mixed models (GLMMs), our results reveal that specific anomalies such as vertebral fusions and anomalous haemal and neural spines affected the curving ability of c-start escape responses, however, these did not negatively …

1 Herpes Simplex Virus Type 1 And Apolipoprotein-E In Alzheimer’S Disease: Virus Entry And Innate Immunity, Jim Camilleri

College of Science and Health Theses and Dissertations

Herpes simplex virus type 1 (HSV-1) is a neurotropic virus that has been detected in brains affected by Alzheimer’s Disease (AD), the leading global cause of cognitive decline. In vitro and epidemiological studies support a role for HSV-1 in AD. The strongest genetic risk factor for late-onset AD is the E4 allele of APOE, which codes for apolipoprotein-E (ApoE), a protein that mediates brain cholesterol homeostasis. Previous work has suggested that ApoE can affect HSV-1 entry into cells; however, APOE has three alleles (E2, E3, and E4) and allelespecific effects of ApoE on HSV-1 entry remain undetermined. We hypothesized that …

Cladia aggregata is a group of lichen-forming fungi comprising multiple species which are difficult to differentiate. C. aggregata has a wide distribution on several different continents but is primarily found in the southern hemisphere. We aimed to further delimit the species complex while also investigating the relatedness of the different species, where they can be found geographically, and what phenotypic traits they possess. We used Restriction Site Associated DNA Sequencing (RAD-seq) to compare thousands of loci across 91 individuals from the Americas, Asia, and Australasia. All Asian samples formed a distinct clade in all phylogenetic trees. Asia, as a distinct …

Regulation Of Spermatogenesis By The Notch Signaling Pathway, Emma O'Flaherty

Master's Theses

The Notch signaling pathway plays a significant role in gonad development and spermatogenesis, but little is known about its specific targets in the testis. The Drosophila testis contains two populations of stem cells: germline stem cells and cyst stem cells, which give rise to differentiating germline and somatic cyst cells, respectively. Notch signaling is activated in the somatic cyst cells by the Delta ligand from the germline in a region of the testes coined the “transition zone”, where somatic cyst cells progress from early cyst cells surrounding gonialblasts and 2-cell germline cysts to late cyst cells surrounding 16-cell spermatocyte cysts. …

Dynamics Of Mangrove Carbon Stock In Selected Uae Coastline: A Remote Sensing Approach, Karthika Kandamkulathil Gopi

Thesis/ Dissertation Defenses

Mangrove ecosystems play a vital role in carbon sequestration by capturing atmospheric CO₂, storing it in aboveground and belowground biomass, and enhancing soil organic carbon (SOC) through litterfall. Arid mangrove ecosystems, such as those in the UAE, experience extreme environmental stressors, leading to distinct variations in biomass allocation and carbon stock estimates compared to tropical regions. This study aims to evaluate biomass accumulation, litterfall production, and SOC storage in selected UAE mangroves. It analyses seasonal litterfall dynamics and assesses the influence of bulk density, soil moisture, and tidal regimes on SOC and aboveground biomass (AGB) across distinct mangrove zones. Field-based …

The Anticancer Activity Of Novel Chromene Derivatives Against Colorectal Cancer Cells, Rym Magramane

Thesis/ Dissertation Defenses

Colorectal cancer (CRC) stands as the third most common cancer globally, accounting for nearly 10% of all newly diagnosed cancer cases. In the UAE, CRC was ranked as the third most frequently diagnosed malignancy, and the leading cause of cancer-associated deaths in 2023. Standard CRC treatment strategies include surgical resection, chemotherapy, immunotherapy, targeted therapy, or a combination of all, depending on the cancer stage and molecular profile. Despite these interventions, disease recurrence is experienced by a considerable number of cancer patients. Hence, there is an urgent need to develop novel alternative treatments to overcome poor prognosis. Recently, cancer research has …

Genetic Structuring Of The Ozark Pocket Gopher (Geomys Bursarius Ozarkensis) And Coevolution With Its Geomydoecus Ectoparasites, Monica Raquel Reusche

Student Theses and Dissertations

The Ozark pocket gopher Geomys bursarius ozarkensis is a highly isolated and restricted subspecies of the plains pocket gopher endemic to Izard Co., Arkansas. This isolation may have impacts genetically and may have caused speciation of their chewing louse. First, I updated the distribution and confirmed occupation at 46 previously documented and 91 additional sites, a 34% increase in areal range. Next, I evaluated natal dispersal which was rare (9.1%) and occurred over shorter distances (≤ 63 m) than for other gopher species. Analysis of single nucleotide polymorphisms from contemporary populations and museum specimens indicated a high genetic structure among …

Highly Adaptable Dendrimer Gel Nanoparticles With Dual Targeting Of Upar And Ribonucleotide Reductase R2 For Better Retention And Improved Therapeutic Outcomes In Triple-Negative Breast Cancer, Hsin Yin Chuang, Da Huang, Lin Qi, Vidit Singh, Anna Chernatynskaya, Yue-Wern Huang, Hu Yang

Biological Sciences Faculty Research & Creative Works

Triple-negative breast cancer (TNBC) accounts for approximately 15% of breast cancers and lacks estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2), rendering it unresponsive to hormonal or anti-HER2 therapies. Due to its poor prognosis and limited treatment options, there is an urgent need for targeted therapies. In this study, we developed highly adaptable polyamidoamine (PAMAM) dendrimer-based gel nanoparticles with dual-targeting capabilities against urokinase-type plasminogen activator receptor (uPAR) and ribonucleotide reductase R2 (R2). These nanoparticles were designed to target both TNBC cells and cancer-associated stromal cells by leveraging uPA-uPAR interactions and delivering the antisense oligonucleotide …

Rethinking Large-Scale Phylogenomics With Eukphylo V.1.0, A Flexible Toolkit To Enable Phylogeny-Informed Data Curation And Analyses Of Diverse Eukaryotic Lineages, Laura A. Katz, Marie Leleu, Godwin Ani, Rebecca Gawron, Auden Cote-L'Heureux

Biological Sciences: Faculty Publications

Eukaryotic diversity is largely microbial, with macroscopic lineages (plants, animals, and fungi) nesting among a plethora of diverse protists. Our understanding of the evolutionary relationships among eukaryotes is rapidly advancing through ’omics analyses, but phylogenomic analyses are challenging for microeukaryotes, particularly uncultivable lineages, as single-cell sequencing approaches generate a mixture of sequences from hosts, associated microbiomes, and contaminants. Moreover, many analyses of eukaryotic gene families and phylogenies rely on boutique data sets and methods that are challenging for other research groups to replicate. To address these challenges, we present EukPhylo v.1.0, a modular, user-friendly pipeline that enables effective data curation …

Anthropogenic Litter In Freshwater Ecosystems: Effect On Ecosystem Processes And Spatial Distribution, Emily Johnson

Master's Theses

The rapid increase of plastic production and disposal into the environment has resulted in anthropogenic litter (i.e., trash; AL) becoming a global problem. In aquatic ecosystems, macro- and microplastics are long-lived, mobile, and interact with the physical and chemical components of aquatic ecosystems. Our objectives were to: (1) assess the impact of microplastic pollution on the ecosystem processes of ecosystem metabolism and N2 flux in an oligotrophic lake and (2) to assess the abundance and assemblage of anthropogenic litter in a large urban river. For objective (1), we added microplastics at a range of concentrations to littoral mesocosms. Ecosystem metabolism …

High-Salt Tumor Microenvironment: Not As Bad As It Sounds, Not As Good As It Seems, Umer Ali, Venkataswarup Tiriveedhi

Biology Faculty Research

Recent evidence suggests a high-sodium microenvironment in breast tumors. However, the exact role of this high-sodium microenvironment on tumorigenesis is unknown. Salt (sodium chloride, NaCl) is a well-known inflammatory molecule playing a significant role in various chronic ailments like cardiovascular and autoimmune diseases. Importantly, chronic inflammation is recognized as one of the major hallmarks of carcinogenesis. Breast cancer cell culture-based studies demonstrated that high-salt (HS) treatment (Δ35–50 mM NaCl) induced cancer cell proliferation. However, preclinical murine research showed reduced tumor progression kinetics in mice fed a short-term HS diet (4% NaCl diet, 0–2 weeks prior to the injection of tumor …
