Observing Growth Effects Of Pigment Epithelium-Derived Factor On Human Retinal Pericytes In Vitro, Anjalee Choudhury, Andrew Tsin, Zachary Perez, Fransisco Elisarraras Sep 2019

The purpose of this study is to investigate and determine the role of PEDF in the pathogenesis of diabetic retinopathy as induced by advanced glycation end-products (AGEs). Human retinal pericytes were isolated from donors and will be measured for cell proliferation under the influence of PEDF both in the presence and absence of AGEs. Expected outcomes involve both the maintenance and increased survival of HRPs after treatment with PEDF under stimulated hyperglycemic conditions.


Assessment Of Physical Fitness After Bariatric Surgery And Its Association With Protein Intake And Type Of Cholecalciferol Supplementation, Hendrika J M Smelt, Sjaak Pouwels, Alper Celik, Adarsh Gupta, Johannes F Smulders Jun 2019

Background: Several studies showed that there is a relationship between vitamin and mineral status and muscle strength. In particular this is the case for handgrip strength (HS) and vitamin D deficiency. In bariatric surgery there is a risk of decrease in muscle strength after surgery and also vitamin and mineral deficiencies are not uncommon. The aim of this study is to assess the effect of low vitamin 25 (OH) cholecalciferol levels, high dose cholecalciferol supplementation regime and protein intake on physical fitness, measured using handgrip strength (HS) and the shuttle walk run test (SWRT). Methods: For this retrospective …


Implications Of Genetic Variation Of Common Drug Metabolizing Enzymes And Abc Transporters Among The Pakistani Population, Nasir Ali Afsar, Henrike Bruckmueller, Anneke Nina Werk, Muhammad Kashif Nisa, H R. Ahmad, Ingolf Cascorbi May 2019

Genetic polymorphism of drug metabolizing enzymes and transporters may influence drug response. The frequency varies substantially between ethnicities thus having implications on appropriate selection and dosage of various drugs in different populations. The distribution of genetic polymorphisms in healthy Pakistanis has so far not been described. In this study, 155 healthy adults (98 females) were included from all districts of Karachi. DNA was extracted from saliva and genotyped for relevant SNVs in CYP1A1, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4 and CYP3A5 as well as ALDH3A1, GSTA1, ABCB1 and ABCC2. About 64% of the participants were born to parents who were unrelated …


Effects Of Ef-24 And Cisplatin On Cancer, Renal, And Auditory Cells, Denis Hodzic Apr 2019

Effects Of Ef-24 And Cisplatin On Cancer, Renal, And Auditory Cells, Denis Hodzic

Masters Theses & Specialist Projects

Cisplatin is a chemotherapy drug effective against several forms of cancer, but can also cause serious side-effects, including nephrotoxicity and ototoxicity. Curcumin, a natural plant compound, can increase cisplatin’s anti-cancer activity and counteract cisplatin’s deleterious effect on the auditory and renal systems. Unfortunately, curcumin exhibits poor bioavailability, which has promoted interest in the development of synthetic curcumin analogs (curcuminoids) that are soluble, target cancer, and do not cause side effects. This study investigated whether the curcuminoid (3E,5E)-3,5-bis[(2-fluorophenyl) methylene]-4-piperidinone (EF-24) increases the anti-cancer effects of cisplatin against a human ovarian cancer cell line (A2780) and its cisplatin-resistant counterpart (A2780cis), while preventing …


Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley Jan 2019

Leucine Supplementation In Cuprizone-Induced Oligodendrocyte Toxicity, Michael Ley

Williams Honors College, Honors Research Projects

Cuprizone is a copper chelator that induces demyelination in the central nervous system when fed to mice. This compound is thought to target Complex IV and disrupt mitochondrial metabolism leading to loss of myelin-producing oligodendrocytes. In this proposal, we further examine the chemical and toxicological properties of cuprizone. Immunofluorescence imaging and microarray data on MO3.13 cells treated with cuprizone revealed the possibility of alterations in lysosomal function, as well as mitochondrial disruption via mTOR and Electron Transport Chain (ETC) related pathways. Cell viability assays conducted suggest that addition of Branched-Chain Amino Acids, most commonly used from literature, leucine, can increase …


Metaproteomic Investigation Of The Vaginal Microbiome In Pregnancy, Zaneera Hassan Jan 2019

Metaproteomic Investigation Of The Vaginal Microbiome In Pregnancy, Zaneera Hassan

Theses and Dissertations

The development of early diagnostics and prevention strategies for preterm birth is an important global health challenge with the potential to impact over 15 million children annually, by improving health outcomes and reducing economic burden. Advances in microbial sequencing technology have opened the door to 16S rRNA gene survey, whole metagenomics, and whole transcriptomics, providing molecular evidence that the composition of the vaginal microbiome affects pregnancy outcomes in women, particularly those of African descent. A current gap in our molecular level understanding of the vaginal microbiome as it relates to healthy pregnancies is the metaproteome which comprises proteins from both …


Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong Jan 2019

Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong

Theses and Dissertations

Bone defects are a pervasive complication arising from many clinical conditions, both mechanical and pathological. Current treatments for large bony defects focus on applying bone grafts or synthetic materials to the defect area. Cell-based—and especially stem-cell—therapies have advanced greatly thanks to increasing attention focused on their ability to generate new tissues in situ with biomechanical properties approaching that of native tissue, but they suffer from their own shortcomings as well. Exosomes have been shown to play critical roles in cell-signaling and tissue regeneration and are therefore potentially ideal therapeutic vehicles for treating bone defects. Exosomes are small microvesicles counted amongst …


Eralpha Isoforms Modulate The Tumorigenicity Of 24r,25(Oh)2d3 In Estrogen-Responsive Cancer, Anjali Verma Jan 2019

Over 200,000 cases of breast cancer are diagnosed every year. Nearly 20% of these patients supplement their diets with some form of vitamin D. This high frequency of vitamin D supplement use may be due in part to research suggesting that cancer patients with higher serum vitamin D3 levels have better prognoses than patients with low serum vitamin D3. However, double-blind clinical trials on the efficacy of vitamin D3 supplementation in breast cancer have been inconclusive. A recent meta-analysis showed evidence of reduced cancer recurrence in patients taking vitamin D3 supplements who had ‘estrogen receptor positive’ …
