Effects Of Statin Drugs And Tocotrienol Rich Fraction Supplementation In Chronic Hemodialysis Patients And Metabolomic Profile, Eno Latifi

Wayne State University Theses

Chronic kidney disease (CKD) is known as a heterogeneous disorder which currently is on the rise and lately has been classified as a public health issues in the United State and worldwide. CKD is an irreversible and progressive disease which can lead to kidney failure, and this is depicted by the advanced stage of the disorder when it reaches the point, that is classified as end stage of renal disease (ESRD) (Stage 5 of CKD) (eGRF <15 mL/min/ 1.73 m2 working capacity), where both organs are in a total or permanent kidney failure. End-Stage renal disease patients, on hemodialysis have been associated to experience an accelerated form of atherosclerosis, which is induced by inflammation, impairment of antioxidant system and elevated oxidative stress. Since the problem effecting ESRD patients is multifactorial, the objective of this investigation is to explore and look at the effects of supplementing with vitamin E-tocotrienol rich fraction (TRF), a micronutrient which has anti-inflammatory, antioxidant, and lipid lower capabilities into tackling these comorbid conditions experienced by this population. Therefore the aims of this investigation will be to explore changes in lipid profiles, inflammatory markers, and oxidative status, as well as look at any changes in metabolomic profiles. It was hypothesized that by supplementing with TRF a vitamin E, for 16 weeks in ESRD patients undergoing hemodialysis, it may help reverse and/or improve, oxidative status, inflammatory markers, increase antioxidants status and improve lipid profiles.

The study was double-blinded, randomized, parallel, placebo-controlled design trial, of 81 adult patients undergoing chronic hemodialysis at Great Lake Dialysis Clinic, Detroit MI, where …

Biophysical Studies Of Mutant H69 Rna Constructs, Daya Nidhi Kharel

Wayne State University Theses

The importance of helix 69 (H69) of the large ribosomal subunit is emphasized by its location in the ribosome and key contacts with protein factors and tRNAs during different steps of protein synthesis. The presence of three highly conserved pseudouridine modifications in H69 has a significant impact on modulation of the ribosome conformations. Specific nucleotides of H69 may be necessary for the function of this helix-loop RNA, as some mutations are deleterious to bacterial growth. In this study, we investigated the effects of single nucleotide mutations in a 19-nucleotide H69 construct with and without pseudouridines on the RNA stability and …

Genetic And Biochemical Studies Of Human Apobec3h Enzyme, Thisari Sachithra Aluthgama Guruge

Wayne State University Theses

The AID/APOBEC enzymes are DNA/RNA cytosine deaminases with important functions in innate and adaptive immunity. APOBEC3 enzymes play a crucial role in restricting the replication of exogenous retroviruses such HIV-1 and endogenous retrotransposition events. In particular, APOBEC3 enzymes have evolved in humans by gene duplication to compose seven members. APOBEC3H is highly diverse in its allelic sequence and the distribution is population-specific. It has evolved under strong positive selection over millions of years. To study the catalytic mechanism, structure, function and the underlying cause of its high diversity, a high resolution crystal or NMR structure is required are not yet …
