Treating Anemia Of Chronic Disease, Sarit Fischer Jan 2020

Treating Anemia Of Chronic Disease, Sarit Fischer

The Science Journal of the Lander College of Arts and Sciences

Anemia of chronic disease (ACD) is the result of altered iron metabolism, blunted erythropoiesis, and shortened red blood cell survival caused by inflammatory cytokines. Hepcidin plays a key role in anemia of chronic disease by inducing endocytosis of the iron exporter ferroportin. Iron is trapped in enterocytes, hepatocytes, and macrophages, and is unavailable for hemoglobin synthesis. When treating the underlying disease is not an option, or anemia is severe, ACD should be treated. While oral iron supplementation is not suitable for ACD, intravenous iron may be effective. Erythropoiesis stimulating agents are a common approach to treating ACD, but a large …

Dye-Encapsulated Ethyl Cellulose As Fluorescence Sensor For Aldehyde Detection, Jinnawat Jongkhumkrong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Over past years, even though lung cancer as one of vital cancer-related mortalities worldwide has inevitably exhibited the highest death rate of entire cancers, there is no facile and convenient diagnosis approaches. The previous researches have reported about long-chain aldehyde compounds such as hexanal, heptanal, octanal, and nonanal as the crucial biomarkers of lung cancer. Nevertheless, the sensing platform for long-chain aldehyde detection have been rarely reported. In this research, the helicene dye-encapsulated ethyl cellulose (EC@dye-NH) nanosensors have achieved the potentially sensitive and specific detection of long-chain aldehyde in aqueous media. As a proof-of-concept, the intrinsic hydrazine group of dye-NH …

Anterior Cruciate Ligament Injury-Induced Alterations In Inflammation And Muscle Physiology, Emily R. Hunt Jan 2020

Anterior Cruciate Ligament Injury-Induced Alterations In Inflammation And Muscle Physiology, Emily R. Hunt

Theses and Dissertations--Rehabilitation Sciences

Long term weakness and atrophy of the quadriceps muscle are a direct result of anterior cruciate ligament (ACL) injuries and persist for up to 10 years post injury. Muscle atrophy ensues regardless of ligamentous reconstruction surgery, indicating that muscle atrophy following injury is a function of the ligament rupture and not reconstruction surgery. Elucidating the mechanisms underlying quadriceps atrophy following ACL rupture is crucial for developing interventions to restore proper quadriceps size and mitigate weakness thereby allowing for improved patient function. In addition to understanding the specific mechanisms that contribute to quadriceps atrophy following ACL rupture, the timing of atrophic …

Determining The Role Of Satellite Cells During Skeletal Muscle Adaptation, Davis A. Englund Jan 2020

Determining The Role Of Satellite Cells During Skeletal Muscle Adaptation, Davis A. Englund

Theses and Dissertations--Rehabilitation Sciences

Physical inactivity, advancing age, limb immobilization, degenerative diseases and various systemic diseases (many cancers, sepsis, HIV, COPD, kidney disease) all lead to skeletal muscle wasting. The loss of muscle mass is of major clinical importance because it leads to an increased risk for morbidity, disability, and the loss of independence; collectively contributing to a substantive increase in healthcare utilization and cost. The prevalence of cachexia (disease-induced muscle wasting) can reach as high as 80% in certain patient populations and the average cost per hospital stay is $4,641 more than in non-cachectic patients. Direct healthcare costs attributable to sarcopenia were estimated …

Electrolytic Oxidative Coupling Of Alcohols With Aldehydes To Form Esters, Katherine L. Verboom Jan 2020

Electrolytic Oxidative Coupling Of Alcohols With Aldehydes To Form Esters, Katherine L. Verboom

Honors College Theses

There are copious amounts of naturally occurring and synthetic esters known that have a wide range of applications in industry to produce fine chemicals. Traditional methods of ester synthesis involve a reaction between a carboxylic acid and an alcohol in the presence of a Bronsted acid catalyst. The primary objective of this research project was to carry out the ester synthesis using the electrochemical coupling of aldehydes with alcohols instead of with a Bronsted acid catalyst because the electrochemical coupling would be an all-around better alternative of ester synthesis than the traditional method of using the catalyst. Electrochemistry has long …

AES Faculty Publications and Presentations

All animals need to find and compete for food, shelter, and mates in order to survive and reproduce. They also need to avoid being eaten by predators. Optimal foraging theory provides a framework to examine the trade-offs individuals make while foraging for food, taking into account an animal’s body condition, predation pressure, quality of food resources, and food patch availability in the habitat. Here we describe an activity that uses Giving Up Densities (GUDs), which could be used as part of a course-based undergraduate research experience (CURE) or as a stand-alone activity. GUDs provide an experimental approach to quantify the …

AES Faculty Publications and Presentations

Estimating the population sizes of animals is a key skill for any student interested in ecology, conservation, or management. However, counting animals in natural habitats is difficult, and the many techniques that exist each rely on assumptions that can bias results. Most wildlife courses teach one or two of these methods, but rarely are students given an opportunity to compare approaches and explore how underlying assumptions affect the accuracy of estimates. Here, we describe a hands-on activity in which students estimate the size of a single population of animals using multiple methods: strip censuses, scat counts, and camera traps. They …

Fabrication, Development, And Characterization Of Hipco Swcnt - Alginate Hydrogel Composites For Cellular Product Applications, Fabian Armando Alvarez-Primo

Open Access Theses & Dissertations

In this study, we designed, synthesized, and characterized ultrahigh purity single-walled carbon nanotube (SWCNT)-alginate hydrogel composites. Among the parameters of importance in the formation of an alginate-based hydrogel composite with single-walled carbon nanotubes, are their varying degrees of purity, their particulate agglomeration and their dose-dependent correlation to cell viability, all of which have an impact on the resultant compositeâ??s efficiency and effectiveness towards biomedical applications. To promote their homogenous dispersion by preventing agglomeration of the SWCNT, at first, we used three different surfactants-sodium dodecyl sulfate (SDS-anionic), cetyltrimethylammonium bromide (CTAB-cationic), and Pluronic F108 (nonionic). After experimentation and corroboration through evidence obtained …
