Effects Of Excitation Pressure On Variegation And Global Gene Expression In Arabidopsis Thaliana, Rainer Bode Dec 2013

Effects Of Excitation Pressure On Variegation And Global Gene Expression In Arabidopsis Thaliana, Rainer Bode

University of Western Ontario - Electronic Thesis and Dissertation Repository

I assessed the effects of photosystem II excitation pressure on chloroplast biogenesis and leaf sectoring in the Arabidopsis thaliana variegated mutants im, spotty, var1, var2, chs5 and atd2. The plants were grown under varying degrees of excitation pressure induced by growth at increasing irradiance at different temperatures and the extent of variegation was quantified throughout the plant’s development. I found that the degree of variegation was positively correlated with excitation pressure, regardless of whether high light or low temperature was used to induce increased excitation pressure in all the mutants tested. This was irrespective of whether the mutation causing ...

Kisspeptin Receptor Agonist (Ftm080) Increased Plasma Concentrations Of Luteinizing Hormone In Anestrous Ewes, Brian K. Whitlock, Kelly A. Chameroy, Rebecca R. Payton, Shinya Oishi, Nobutaka Fujii, Joseph A. Daniel Aug 2013

Kisspeptin Receptor Agonist (Ftm080) Increased Plasma Concentrations Of Luteinizing Hormone In Anestrous Ewes, Brian K. Whitlock, Kelly A. Chameroy, Rebecca R. Payton, Shinya Oishi, Nobutaka Fujii, Joseph A. Daniel

Brian K Whitlock, PhD, DVM, DACT

Kisspeptin (KP) and the KP receptor (Kiss1r) are integral to central regulation of the gonadotropic-axis. The demonstration that intravenous infusion of KP can stimulate gonadotropin secretion and ovulation in seasonally anestrous female sheep offers a means of manipulating the reproductive axis. However, KP may be of limited clinical use because of the short circulating half-life. Kiss1r agonists with increased half-life and similar efficacy to KP in vitro potentially may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. This study was designed to test and compare the effects of ...

Brian K Whitlock, PhD, DVM, DACT

Castration may detrimentally affect the health and performance of weaned calves, and painful procedures are increasingly becoming a public concern. The objective of this study was to determine the effects of castration (by banding) with or without administration of meloxicam, a non-steroid anti-inflammatory, on performance and inflammatory response in weaned beef calves. Forty-eight (weaned) beef calves [10.0±0.2 mo old; 304±6 kg BW] were blocked by age, BW, wither height, scrotal circumference, and source, then randomly assigned to 1 of 3 treatments (n=16 calves per treatment: 1) intact bulls (BULL), 2) castration by banding (BAN), or ...

Brian K Whitlock, PhD, DVM, DACT

Castration may detrimentally affect the health and performance of weaned calves and painful procedures are increasingly a public concern. Therefore, practical pain mitigation is critical. The objective was to determine the effects of castration (by banding) with or without administration of NSAID, meloxicam, on the behavior of weaned beef calves. Forty-eight (56 d post-weaning) beef calves [10.0 ± 0.2 (mean ± SE) mo old; 304 ± 6 kg BW] were blocked by multiple factors then randomly assigned to 3 treatments (n = 16 calves per treatment: 1) intact bulls (BULL), 2) castration by banding (BAN), or 3) castration by banding with orally-administered ...


Raman Spectroscopic Analysis Of Human Skin Tissue Sections Ex-Vivo: Evaluation Of The Effects Of Tissue Processing And Dewaxing, Syed Mehmood Ali, Franck Bonnier, Ali Tfayli, Helen Lambkin, Kathleen Flynn, Vincent Mcdonagh, Claragh Healy, Thomas Lee, Fiona Lyng, Hugh Byrne Jun 2013

Raman Spectroscopic Analysis Of Human Skin Tissue Sections Ex-Vivo: Evaluation Of The Effects Of Tissue Processing And Dewaxing, Syed Mehmood Ali, Franck Bonnier, Ali Tfayli, Helen Lambkin, Kathleen Flynn, Vincent Mcdonagh, Claragh Healy, Thomas Lee, Fiona Lyng, Hugh Byrne

Articles

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections, and the effects of tissue processing. Both hand and thigh sections of human cadavers were analysed in their unprocessed and formalin fixed paraffin processed (FFPP) and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differentiation of the stratum corneum, intermediate underlying epithelium and dermal layers for sections from both anatomical sites. The stratum corneum is seen to be relatively rich in lipidic content; the spectrum of the subjacent layers is strongly influenced by the presence of melanin, while that ...

The Role Of Minimization And Facilitation Of Learner Involvement During Acquisition In The Learning Of A Motor Task, Elizabeth A. Sanli May 2013

The Role Of Minimization And Facilitation Of Learner Involvement During Acquisition In The Learning Of A Motor Task, Elizabeth A. Sanli

Open Access Dissertations and Theses

When learning a new motor skill, how we choose to go about the learning process can influence how quickly and how well we learn the task. In particular, the role of learner involvement during the acquisition period can be manipulated through how practice is scheduled. Two separate sets of literature (progression of task difficulty and self-controlled practice) which discuss learner involvement during acquisition were reviewed. The motivation behind this thesis is to examine the effects of progressive and self-controlled practice on measures of retention, transfer and dual-task performance as well as to attempt to determine the underlying factors responsible for ...


A Survey Of Ionoregulatory Responses To Extended Exercise And Acute Hypoxia In Freshwater Amazonian And Southern Ontarian Teleosts: Investigating The Osmorespiratory Compromise, Lisa M. Robertson Msc May 2013

A Survey Of Ionoregulatory Responses To Extended Exercise And Acute Hypoxia In Freshwater Amazonian And Southern Ontarian Teleosts: Investigating The Osmorespiratory Compromise, Lisa M. Robertson Msc

Open Access Dissertations and Theses

The osmorespiratory compromise is the trade-off between high gill permeability for oxygen uptake and low gill permeability for conservation of ions in fish. The fundamental purpose of this study was to examine facets of the osmorespiratory compromise in freshwater fish under conditions of extended exercise and acute hypoxia, in light of previous research identifying very different gill morphometric and ionoregulatory modifications in the hypoxia-tolerant Amazonian oscar (Astronotus ocellatus) and the hypoxia-intolerant rainbow trout (Oncorhynchus mykiss). A technique using [3H]polyethylene-4000 ([3H]PEG-4000) for branchial paracellular permeability measurement was developed, and then applied to investigate the osmorespiratory compromise during ...


Exploring The Sulfide Tolerance Of Ectosymbiotic Niphargus Amphipods From The Frasassi Caves, Central Italy, Jan Bauermeister, Karoline Assig, Sharmishtha Dattagupta May 2013

Exploring The Sulfide Tolerance Of Ectosymbiotic Niphargus Amphipods From The Frasassi Caves, Central Italy, Jan Bauermeister, Karoline Assig, Sharmishtha Dattagupta

International Journal of Speleology

Two species of the crustacean amphipod genus Niphargus inhabit the sulfidic groundwaters of the Frasassi caves in central Italy, and both harbor filamentous, sulfide-oxidizing Thiothrix ectosymbionts. As sulfide is toxic to most aerobic organisms, it appeared possible that the ectosymbionts could help their Niphargus hosts with detoxification processes. In this study, mortality due to sulfide was compared between Niphargus individuals with ectosymbionts and individuals whose ectosymbionts had been killed by antibiotic treatment. Both Frasassi-dwelling Niphargus species revealed exceptionally high tolerances to sulfide compared to other amphipod species studied so far. Niphargus individuals without viable ectosymbionts tolerated sulfide levels exceeding those ...

Schizophrenia: Then And Now, Christina Lee May 2013

Schizophrenia: Then And Now, Christina Lee

Sound Neuroscience: An Undergraduate Neuroscience Journal

The term "schizophrenia" was introduced over 100 years ago and it is a psychological disorder characterized by a loss of contact with reality as well as a disruption of thought, perception, mood, and movement. Throughout the years, a lot of information has been uncovered but there is still a lot of progress to be made in terms of understanding its etiology and in creating effective treatment options.


The Progression Of A Disease: An Overview Of Schizophrenia, Lucas Stone May 2013

The Progression Of A Disease: An Overview Of Schizophrenia, Lucas Stone

Sound Neuroscience: An Undergraduate Neuroscience Journal

Schizophrenia is a largely undiscovered disease. Researchers haven't discovered a mechanism for effects and they still do not completely know how it affects the brain. The COMT gene as well as the epigenetic regulation of certain glutaminergic and GABAergic neurotransmitters have been proposed as possible causes for Schizophrenia, but like most research of this disease, it is not proven. The treatment for this disease has gotten better, but there still is not one that does not involve altering the natural processes of the brain.


Reexamination Of Herpetofauna On Mormon Island, Hall County, Nebraska, With Notes On Natural History, Keith Geluso, Mary J. Harner May 2013

Reexamination Of Herpetofauna On Mormon Island, Hall County, Nebraska, With Notes On Natural History, Keith Geluso, Mary J. Harner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Platte River in central Nebraska, USA, was historically surrounded by mixed grass and tallgrass prairies and wet meadows, but many of those habitats were lost or altered during the last century with unknown effects on animals that reside in them. Researchers first surveyed herpetofauna on part of a large island preserve in the Platte River, Mormon Island, Hall County, Nebraska, in 1980 when the land was protected for conservation. They documented 10 species, including three species of amphibians and seven species of reptiles. We inventoried herpetofauna after 30 years of conservation management on Mormon Island and adjacent Shoemaker Island ...
