Assessment Of Fifth Metatarsal Etiology, Daniel Reed

All Theses

The fifth metatarsal 'Jones Fracture' is a fracture that occurs 3.5cm distal to the tuberosity. It is an injury that is common in athletes, especially those who participate in sports with a lot of lateral movement. The Jones Fracture is known for its difficulty to heal due to non-union and re-fracture. There has been much research recently regarding in-shoe pressure distributions and their relation to shoe type, movement, and shoe surface interaction. However, only the forces along the bottom of the foot have been investigated. Literature and the direction of fracture seem to implicate a force on the lateral portion …

Manipulations Of Macrophage Activation Through Targeted Delivery Of Interferon Regulatory Factor Genes Mediated By Recombinant Adenovirus-Conjugated Zymosan, Mengmeng Zhang

All Theses

According to the different phenotypes and distinct patterns of gene expression, macrophages can be subdivided into two types: M1 and M2. The M1 macrophages, which are activated through the classical pathway, have a proinflammatory characteristic, providing an in-front defense line against different kinds of pathogens as well as malignant cells. On the other hand, the M2 macrophages are immunosuppressive and instead can promote tumor growth and dissemination. The solid tumor tissues are often infiltrated with a large number of macrophages, the so-called tumor-associated macrophages (TAMs). TAMs, which are polarized into M2 phenotype under the tumor microenvironment, promote tumor progression by …

Investigating Risks, Effects, And A Potential Management Strategy For Avian Vacuolar Myelinopathy On Southeastern Reservoirs Using An Eco-Epidemiological Approach, Rebecca Haynie

All Dissertations

Avian vacuolar myelinopathy (AVM) is a neurologic disease of unknown etiology that has severely impacted waterbirds and raptors in the Southern United States since it was first diagnosed in 1994. Research studies have suggested that the causative agent is a neurotoxin produced by a previously undescribed Stigonematalan cyanobacterium which grows epiphytically on submerged aquatic vegetation. A suite of experiments were conducted to determine if: (1) triploid Chinese grass carp (Ctenopharyngodon idella) are an appropriate management strategy for AVM; (2) to measure mammalian susceptibility to cyanobacterium exposure; and, (3) to discern population-level impacts to American coots (Fulica americana) and bald eagles …

Engine Performance Test Of Cottonseed Oil Biodiesel, Xiaohu Fan, Xi Wang, Feng Chen, Daniel P. Geller, Peter J. Wan

Publications

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8%, CO2 by 11.1% and NOx by 10%, though there was no significantly statistical difference at p<0.05. The engine test also showed a slightly higher amount of consumption and less tendency of coke formation from COME than the No. 2 diesel fuel. The oxidative stability study showed COME with acceptable stability. COME exhibited friendly environmental benefits and acceptable stability, demonstrating its feasibility as an alternative fuel.
