Study Of Apparent Molar Volumes Of Electrolyte Solutions And Its Application In Medicine, Muratali I. Bazarbayev, Qumrijon I. Narziqulova, Islom Mullojonov, Erkinbay Ya. Ermetov

Central Asian Journal of Medicine

All biological processes in plant or animal organisms, including in the human body, are carried out in solutions. Therefore, the progress of sciences such as biology, medicine, etc., is closely related to the development of the doctrine of solutions. When dissolved, various chemical interactions occur between the components and due to Van der Waals force, etc. One of the methods for determining the ion molecular interaction is the study of the partial molar volume of electrolytes.

Complement-Mediated Selective Tumor Cell Lysis Enabled By Bi-Functional Rna Aptamers, Hua Shi, Prabhat K. Mallik, Kimi Nishikawa, Pramit Mallik

Biological Sciences Faculty Scholarship

Unlike microbes that infect the human body, cancer cells are descended from normal cells and are not easily recognizable as “foreign” by the immune system of the host. However, if the malignant cells can be specifically earmarked for attack by a synthetic “designator”, the powerful effector mechanisms of the immune response can be conscripted to treat cancer. To implement this strategy, we have been developing aptamer-derived molecular adaptors to invoke synthetic immune responses against cancer cells. Here we describe multi-valent aptamers that simultaneously bind target molecules on the surface of cancer cells and an activated complement protein, which would tag …

Implications Of Salinity Normalization Of Seawater Total Alkalinity In Coral Reef Metabolism Studies, Travis A. Courtney, Tyler Cyronak, Alyssa J. Griffin, Andreas J. Andersson

Marine & Environmental Sciences Faculty Articles

Salinity normalization of total alkalinity (TA) and dissolved inorganic carbon (DIC) data is commonly used to account for conservative mixing processes when inferring net metabolic modification of seawater by coral reefs. Salinity (S), TA, and DIC can be accurately and precisely measured, but salinity normalization of TA (nTA) and DIC (nDIC) can generate considerable and unrecognized uncertainties in coral reef metabolic rate estimates. While salinity normalization errors apply to nTA, nDIC, and other ions of interest in coral reefs, here, we focus on nTA due to its application as a proxy for net coral reef calcification and the importance for …

A Comparison Of Solid Electrolyte Interphase Formation And Evolution On Highly Oriented Pyrolytic And Disordered Graphite Negative Electrodes In Lithium-Ion Batteries, Haoyu Zhu, Joshua A. Russell, Zongtang Fang, Pete Barnes, Lan Li, Corey M. Efaw, Allison Muenzer, Jeremy May, Kailash Hamal, I. Francis Cheng, Paul H. Davis, Eric J. Dufek, Hui Xiong

Materials Science and Engineering Faculty Publications and Presentations

The presence and stability of solid electrolyte interphase (SEI) on graphitic electrodes is vital to the performance of lithium-ion batteries (LIBs). However, the formation and evolution of SEI remain the least understood area in LIBs due to its dynamic nature, complexity in chemical composition, heterogeneity in morphology, as well as lack of reliable in situ/operando techniques for accurate characterization. In addition, chemical composition and morphology of SEI are not only affected by the choice of electrolyte, but also by the nature of the electrode surface. While introduction of defects into graphitic electrodes has promoted their electrochemical properties, how such structural …

The Utilization Of Enzymes And Enzyme Products For Antimicrobial Effects, Brandon Edward Burdette

Theses and Dissertations

Bacterial resistance is outpacing the discovery of novel antimicrobials. Therefore, it is essential to look at antimicrobials using novel methods. MTAN is a crucial enzyme for some bacteria such as Helicobacter pylori. Transition state analog inhibitor design and fragment-based drug design are drug design approaches typically used independently, but combining these techniques yields inhibitors that bind tightly and are effective in pM concentrations. We demonstrate the efficacy of the combined techniques by investigating the inhibition of HpMTAN, which is an essential enzyme. Enzyme byproducts can also be effective for causing bacterial cell death, hydrolyzing GsdmD by caspases-1/4/5/11 results in an …

These players are shown attaching themselves to their virtual selves so much that they deny their real-world selves, and are then manipulated by the Erebos AI to commit acts of violence. On the other hand, the novel reveals that such obsession can be solved …

Water-Use Efficiency And Infiltration Under Different Rangeland Conditions And Cultivation In A Semi-Arid Climate Of South Africa, Hennie A. Snyman

IGC Proceedings (1977-2023)

The objective of this study was to determine the impact of rangeland in different botanical composition classes (good, moderate and poor), on water-use efficiency (WUE: crude protein produced per unit of evapotranspiration) and soilwater content. The same measurements were also made on an undisturbed bare soil surface and soil cultivated twice per annum. Evapotranspiration was determined by quantifying the soil-water balance equation with the aid of runoff plots and soil-water content measurements done by a neutron hydroprobe. Water-use efficiency declined significantly (P ≤ 0.01) with rangeland degradation. Rangeland in good condition averaged a WUE of 0.28 kg crude protein ha …

IGC Proceedings (1977-2023)

Serrated tussock (Nassella trichotoma) is the most serious perennial grass weed in southeastern Australia, extending over more than a million hectares. Previous control techniques using herbicides and oversowing with competitive pastures are no longer feasible in many of the lower fertility, infested areas. New management solutions need to be found, based upon a better understanding of the ecology of this species. A survey was done to determine the community structure of serrated tussock infested grasslands. Winter growing C3 grasses were closely associated with serrated tussock, while C4 perennial grasses appeared not to be. It is not known if …

Valuing The Pasture Resource - Importance Of Perennials In Higher Rainfall Regions Of South Eastern Australia, P. M. Dowling, R. E. Jones, David R. Kemp, D. L. Michalk

IGC Proceedings (1977-2023)

The premature decline of perennial grass based pastures in southern temperate Australia results in poor productivity and unstable pastures that allow invasion by less desirable weedy species and the potential for soil degradation. The loss of perennial species is attributed to overgrazing arising from an undervaluation of the pasture resource. Resowing pastures is largely uneconomic so maintenance of, or increasing the perennial, is dependent on improved grazing and pasture management practices. A key to changing perceptions is valuing the true worth of the perennial component. Results are presented from a model that takes into account the seasonality of production of …

Exploring The Relationships Among Stoichiometric Coefficients, Number Of Transferred Electrons, Mean Oxidation Number Of Carbons, And Oxidative Ratio In Organic Combustion Reactions, Pong Kau Yuen, Cheng Man Diana Lau

Faculty Publications

Combustion reactions, stoichiometry, and redox reactions are some of the basic contents in chemistry curriculum. Although the counting of transferred electrons is critical in redox reactions, assigning mean oxidation number of organic carbons (ONc) is not always easy. Even though the relationship between the oxidative ratio (OR) and ONc is known, the relationship between the number of transferred electrons (Te−) and OR has not been thoroughly studied. The H-atom method has already been developed to balance and deduct organic combustion reactions. It can be used further to help establish the relationships among the stoichiometric coefficients (SC), the number of transferred …

The Question Of Veganism, The Dangers Of Moral Extensionism, And A Pragmatist Ecofeminist Alternative, Erin Mckenna

Between the Species

In this paper I argue that the framework of moral extensionism relies on human exceptionalism and human centeredness. I discuss the dangers of human exceptionalism and human centeredness using the work of ecofeminist philosophers Val Plumwood, Carol Adams, Lori Gruen, A. Breeze Harper, and Lisa Kemmerer. These ecofeminists each articulate alternative approaches to human relations with other animal beings. There are tensions among these alternatives, though, and I use a pragmatist perspective to interrogate their different positions on how other animal beings should or should not figure into the diets of human beings. I will argue that we need a …

Genome-Wide Analysis Of Methylome In The Mouse Brain Using Long-Read Sequencing Technology, Zachary Even, He Huang, Ramkumar Mathur, Xusheng Wang

Arts & Sciences Undergraduate Showcase

DNA methylation is an epigenetic modification that transfers a methyl group onto the C-5 position of the cytosine to form 5-methylcytosine. DNA methylation regulates gene expression by recruiting proteins involved in gene repression or by inhibiting the binding of transcription factor(s) to DNA, especially in regulation of Allele Specific Expression (ASE). In this study, we used Oxford Nanopore long-read sequencing technology to profile methylome in the two inbred mouse strains, C57BL/6J (B6) and DBA/2J (D2). Compared with bisulfite conversion followed by Illumina Sequencing, long-read sequencing technology allows us to achieve much longer read length of 4,653.675 base pairs on average …
