Efficient topical drug delivery remains a significant challenge in glaucoma management. Although nanoparticle formulations offer considerable promise, their complex preparation processes, co-delivery issues, and batch consistency have hindered their potential. A scalable fabrication strategy is developed here for preparing solid drug nanoparticles (SDNs) with enhanced drug delivery efficiency. Utilizing hydrophobic antiglaucoma drugs brimonidine (BM) and betaxolol (BX), uniform fixed combination BM/BX SDNs are fabricated through a continuous process, improving batch-to-batch consistency for combined glaucoma treatment. With trehalose being used as a lyoprotectant, BM/BX SDNs can be stored as dry powder and easily reconstituted in phosphate buffered saline. Importantly, reconstituted BM/BX …

Understanding the dynamics of mixed-gas adsorption is essential for industrial-scale adsorptive separations. Also, obtaining binary adsorption isotherms is essential to gain a better understanding of adsorbate-adsorbent interactions in multicomponent gas mixtures. Porous organic cages (POCs) are highly porous, crystalline materials, with a small average pore window that make them promising candidates for separation applications. In this work, we utilized zero-length column (ZLC) technique to not only determine the kinetics of CO2/H2 separation over CC3 but also obtain the binary adsorption isotherms. The ultra crystalline diffusivities of 1.49 x 10–4 and 8.31 x 10–5 cm2 …

To investigate continental dynamics underneath the south-central Tibetan plateau, which composes the Himalayan, Lhasa, and Qiangtang blocks, we have conducted comprehensive examinations of seismic azimuthal anisotropy in the crust using receiver functions (RFs) and crustal and mantle anisotropy using teleseismic shear wave splitting (SWS) analysis. In the Qiangtang block, the observed predominantly E-W fast orientations from RF and SWS analyses with similar magnitude are interpreted as resulting from eastward crustal flow with minor contributions from the mantle. In the Lhasa block, the crustal anisotropy is approximately N-S oriented, which is parallel to the strike of rift basins and southward crustal …

Polymer-supported MOF composites have emerged as versatile candidates for various separation and catalytic applications. In this study, we demonstrate design and development of UiO-67-coated Ce(OH)4@PIM-1 composites via dip-coating, drop-casting, solid-phase coating, and supramolecular assembly, and assess their preparation-structure-performance relations. The catalytic performance of the composites was investigated through hydrolysis of dimethyl 4-nitrophenyl phosphate (DMNP), as a nerve agent simulant. The findings revealed that while dip-coating method was unable to achieve a thick and uniform coverage of the MOF layer on the Ce(OH)4@PIM-1, the supramolecular assembly gave rise to 16 wt.% MOF loading and the composite prepared …

The recognition of incised valleys and the reconstruction of their filling history are significant for defining unconformity surfaces and their stratigraphic framework, particularly when detailed petrographic data are missing. However, little of such research is published so far on the characterization and factors influencing the development of incised valleys using three-dimensional seismic and well data. Thus, this work aims to examine and analyze the geometry and factors controlling the formation and sediments filling of an eocene incised valley in a sequence stratigraphic frame using an integration of three-dimensional seismic and well data from ne sirte basin, libya.

In the present study, we use broadband seismic data recorded by 190 stations of the EarthScope program's Transportable Array to construct a 3-D shear wave velocity model for the upper 180 km using a non-linear Bayesian Monte-Carlo joint inversion of receiver functions (RFs) and Rayleigh wave dispersion curves. Ambient noise and teleseismic data are used for obtaining Rayleigh wave phase velocity dispersion curves. A resonance removal filtering technique is applied to the RFs contaminated by reverberations from the thick sedimentary layers that cover most of the region. Our observations of the higher crustal shear velocities (∼3.40 km/s) beneath the Sabine …

The naturally occurring amino acid, l-ergothioneine (EGT), has immense potential as a therapeutic, having shown promise in the treatment of other disease models, including neurological disorders. EGT is naturally uptake into cells via its specific receptor, OCTN1, to be utilized by cells as an antioxidant and anti-inflammatory. In our current study, EGT was administered over a period of 6 months to 25–26-month-old CBA/CaJ mice as a possible treatment for age-related hearing loss (ARHL), since presbycusis has been linked to higher levels of cochlear oxidative stress, apoptosis, and chronic inflammation. Results from the current study indicate that EGT can prevent aging …

To advance our comprehension of the complex geological history and mantle dynamics in the north atlantic region, we employ all available broadband seismic data recorded in greenland to reveal an abnormal mantle transition zone (mtz) structure. Central and eastern greenland exhibits depressed 410 and 660 km discontinuities (d410 and d660, respectively) bordering the mtz, indicative of a substantial thermal anomaly associated with an underlying plume, surpassing the 1,800°c threshold for post-garnet phase transitions at the d660. Variations in mtz thickness across greenland stem from differing temperature anomalies at the d410 and d660, possibly linked to a tilted plume within the …

Undergraduate Research Conference at Missouri S&T
In this project ionizable lipids were analyzed for their efficacy in delivery of mRNA in multiple metastatic lung cancer cells. Different ionizable lipids with their molar ratio in making the LNPs were analyzed in order to enhance the nucleic acid delivery to cytoplasm. Phospholipids also play a role in targeting efficacy of the LNPs to the lung cells. Different combination of ionizable lipids with multiple phospholipids were studied for physical characterization and in-vitro transcription efficiency. Transcription efficiency was then quantified using flow cytometry and optimal particles for transcription were noted.

Lipopolysaccharides (LPS), also known as endotoxins, are toxins released from the cell walls of gram-negative bacteria upon their death. Ingestion of LPS by humans or animals can initiate inflammatory immune responses, resulting in blood vessels dilation, organ dysfunction and potential death. These toxins contaminate a variety of manufacturing processes from the pharmaceutical industry to animal feed production, posing a risk to humans and animals alike. This study details the production of PCL nanoparticle capable of removing LPS from water and a preliminary analysis of the removal efficiency. The outcomes of this research hold significant implications for industries reliant on bacterial …

In a previous project it was determined ALC polarized lipid nanoparticles have a high transfection efficiency in some lung cancer cell lines. Building off this information, these ALC particles will now be tested with an actual lung cancer drug. This process will consist of searching articles for promising lung cancer drugs and selecting one for use. The ALC particles will then undergo a comprehensive drug study using multiple lung cancer cell lines with the selected drug. Aspects such as drug release rate, transfection rate, cytotoxicity, etc. will be determined. The goal is to determine whether ALC nanoparticles show real promise …

Healthcare associated infections are significant concern in medicine and as antibiotics are becoming less effective, we need new alternative methods to treat them. We are testing various materials that can be used to prevent infections in healthcare settings and in wound treatments. These materials include bioactive glass and modified hydrogel materials. From these studies we've learned these are effective in killing bacteria and preventing infections. The goal of this project is to determine the mechanism at which these materials kill bacteria. Our approach is to construct biosensor strains that can indicate bacterial stress response to antimicrobial agents. We have used …
