Bioremediation Of Landfill Gas Under Laboratory Conditions / Navarani A/P Vejaratnam, Navarani Vejaratnam

Student Works (2000-2009)

Per capita generation of municipal solid waste (MSW) in Malaysia has reached 1.3kg per day giving a total generation of more than 31000 tonnes daily. All the MSW collected are disposed into 260 landfills or dumps with 90% of the landfills being non-sanitary. Due to lack of proper gas collection facilities, almost all the methane produced are released passively to the atmosphere.Malaysian landfills produce 1.3-7.5 L/kg/year of methane gas. Since methane is 23 times more harmful as greenhouse gas than CO2, it is essential to mitigate its emission from landfills. One option to reduce methane emissions is to oxidize the …

Delayed Rejection Of Mhc Class Ii-Disparate Skin Allografts In Mice Treated With Farnesyltransferase Inhibitors, Ken Field

Faculty Journal Articles

Farnesyltransferase inhibitors (FTIs), developed as anti-cancer drugs, have the potential to modulate immune responses without causing nonspecific immune suppression. We have investigated the possibility that FTIs, by affecting T cell cytokine secretion, can attenuate alloreactive immune responses. The effects of FTIs on murine alloreactive T cells were determined both in vitro, by measuring cytokine secretion or cell proliferation in mixed lymphocyte cultures, and in vivo, by performing skin allografts from H-2^bm12mice to MHC class II-disparate B6 mice. We found that two different FTIs, ABT-100 and L-744,832, blocked secretion of IFN-γ, IL-2, IL-4, and TNF-α from naïve …

Age May Be Hazardous To Outcome Following Traumatic Brain Injury: The Mitochondrial Connection, Lesley Knight Gilmer

University of Kentucky Doctoral Dissertations

Older individuals sustaining traumatic brain injury (TBI) experience a much higher incidence of morbidity and mortality. This age-related exacerbated response to neurological insult has been demonstrated experimentally in aged animals, which can serve as a model to combat this devastating clinical problem. The reasons for this worse initial response are unknown but may be related to age-related changes in mitochondrial respiration.

Evidence is shown that mitochondrial dysfunction occurs early following traumatic brain injury (TBI), persists long after the initial insult, and is severitydependent. Synaptic and extrasynaptic mitochondrial fractions display distinct respiration capacities, stressing the importance to analyze these fractions separately. …

Awareness Of Increased Risk For Heart Disease And Cardiovascular Risk Factors In Women With Systemic Lupus Erythematosus, Patricia Weinstein

Electronic Theses and Dissertations

Women with systemic lupus erythematosus (SLE) develop cardiovascular disease (CVD) earlier and at a more accelerated rate compared to women without SLE. Many women with SLE are unaware of their increased risk despite years spent in the health care system, thus giving the atherogenic process time to accrue damage. Research has not explained fully why women with SLE are unaware of their increased risk for CVD or why awareness does not correspond to risk-educing behaviors. Stage theories of behavior like the Precaution Adoption Process Model (PAPM) propose that health behavior change proceeds through qualitatively different stages, and people at one …
