Myxosporidiosis In Oreochromis Niloticus; Molecular Identification And Oxidative Stress Biomarkers, Nevien Abdelkhalek, M. El-Adl, M. Hamed, M. Al-Araby

Mansoura Veterinary Medical Journal

Myxosporidiosisis a protozoan parasitic fish disease that causes damages to fish organs and might eventually end with mortalities and deterioration of meat quality of the affected fish. The presence of parasitic infestation is usually accompanied with the production of reactive oxygen and nitrogen species that produces extra damage to host organs and inactivation of antioxidant defense system that increase the intensity of parasitic infestation. Recently, the response of the infested tissue to oxidative stress is varieddepending on the type of parasite; therefore the use of oxidative stress markers as indicator for myxobolus infestation is relevant. In the present study, Oreochromis …

Estimating Density And Residency Of Bottlenose Dolphins (Tursiops Truncatus) In Three Estuarine Sites In South Carolina, Jessica Nicole Conway

Electronic Theses and Dissertations

Of the three estuarine bottlenose dolphin stocks in South Carolina, two are considered data insufficient, with no minimum population estimate or assigned potential biological removal value. Additionally, the Northern Georgia Southern South Carolina Estuarine System (NGSSCES) stock’s boundaries are based on sighting data that do not extend to the full area encompassed by the boundary lines. In areas where stock boundaries are not clearly defined and data is insufficient for traditional methods of estimating abundance, density may provide insight into local distributions and serve as a proxy for actual abundance. Photo-identification surveys were conducted in three sites, representative of the …

Unravelling The Correlation Of Electronic Structure And Carrier Dynamics In Cuins2 Nanoparticles, Wenhui Hu, John Ludwig, Brian Pattengale, Sizhuo Yang, Cunming Liu, Xiaobing Zuo, Xiaoyi Zhang, Jier Huang

Chemistry Faculty Research and Publications

In this work, we report the direct correlation of photoinduced carrier dynamics and electronic structure of CuInS₂ (CIS) nanoparticles (NPs) using the combination of multiple spectroscopic techniques including steady-state X-ray absorption spectroscopy (XAS), optical transient absorption (OTA), and X-ray transient (XTA) absorption spectroscopy. XAS results show that CIS NPs contain a large amount of surface Cu atoms with ≪four-coordination, which is more severe in CIS NPs with shorter nucleation times, indicating the presence of more Cu defect states in CIS NPs with smaller size particles. Using the combination of OTA and XTA spectroscopy, we show that electrons are trapped …

Lyme Disease Ecology: Effects Of Habitat And Hosts On The Density And Distribution Of Borrelia Burgdorferi-Infected Ixodes Scapularis, Megan Ainsley Linske

Doctoral Dissertations

The research discussed in this dissertation examined host and habitat composition in Connecticut and their effect on the ecology of Lyme disease. Previous studies on management strategies sought a one-size-fits-all solution. However, Connecticut may require its own implementation of management strategies supported by research executed in its respective environment. Therefore, a novel approach that addresses the key components of a particular habitat, in this case Connecticut’s northern hardwood forests with an invasive plant understory, may yield better results than a “silver bullet” solution produced by a model or conducted in a different geographic location.

My research is conducted in Connecticut …

Optimizing Fabrication And Modeling Of Quantum Dot Superlattice For Fets And Nonvolatile Memories, Pial Mirdha

Antioxidant Trace Elements And Oxidative Stress Status In Dairy Cattle Suffering From Mastitis, Medhat Nassif, Hussam Ibrahim, Heba Moharam

Mansoura Veterinary Medical Journal

Mastitis is an inflammation of the mammary glands caused by several pathogens. Reactive oxygen species are natural end products of the intensive cellular metabolism. Oxidative stress occurs when there is a disturbance of homeostasis causing inflammation of the mammary gland. This study was performed to evaluate blood antioxidant profile and trace elements in dairy cows with clinical mastitis. For this aim, venous blood samples were collected from 116 cows (100 mastitic, 16 control). In cows with clinical mastitis, there was a significant (p < 0.05) increase in the clinical index score compared with control group. Biochemically, there was a significant (p < 0.05) decrease in super oxide dismutase, catalase and total antioxidant capacity as well as in the level of zinc. However, there was a significant (p < 0.05) increase in the levels of malondialdehyde and glutathione reductase as well as in that of copper. The results of the current study indicate that the body antioxidant defense system was compromised in dairy cows with clinical mastitis creating a state of oxidative stress.
