Methylation of PP2A in Arabidopsis thaliana - effects on gene expression and phenotype
(Bachelor thesis, 2021)Methylation of the carboxyl group in PP2A and formation of the PP2A holoenzyme is a highly regulated process. The catalyzer of this process is Leucine carboxyl methyl transferase 1 (LCMT1). PP2A-C methylation is essential ... -
Synthesis, characterization, and Batch adsorption analysis of Spent coffee grounds, Chitosan, and PVA composite beads for the removal of Cadmium and Lead from aqueous solutions.
(Master thesis, 2021)Adsorption of Cadmium and Lead in aqueous solutions by Spent coffee grounds/chitosan/PVA composite beads was studied. An adsorption Batch experimental model was used to determine the Isotherms and kinetics of 4 different ... -
Uracil-excising activity of hSMUG1 in bubble and R-loop DNA
(Master thesis, 2021)Uracil arises in cellular DNA by hydrolytic cytosine (C) deamination and by erroneous repli-cative incorporation of deoxyuridine monophosphate opposite adenine. The former event is devastating by generation of C thymine ... -
Potential of ultrasound technology towards improvement of protein gel systems as affected by thermal and high-pressure processing as pre-treatment.
(Master thesis, 2021)The potential of ultrasound (US) to modify structural and functional properties in complex protein food systems has gained more interest in recent years.US-enhanced gelling properties have been demonstrated in acid ... -
Advances in the Study of Gas Hydrates by Dielectric Spectroscopy
(Peer reviewed; Journal article, 2021)The influence of kinetic hydrate inhibitors on the process of natural gas hydrate nucleation was studied using the method of dielectric spectroscopy. The processes of gas hydrate formation and decomposition were monitored ... -
Further Investigation of Solvent Synergists for Improved Performance of Poly(N-vinylcaprolactam)-Based Kinetic Hydrate Inhibitors
(Peer reviewed; Journal article, 2021)Poly(N-vinylcaprolactam) (PVCap) and related copolymers have been used as kinetic hydrate inhibitors (KHIs) to combat gas hydrate formation in oil and gas field production flow lines. It is known that the addition of certain ... -
N‑Oxide Polyethers as Kinetic Hydrate Inhibitors: Side Chain Ring Size Makes the Difference
(Peer reviewed; Journal article, 2021)The formation of gas hydrates in flow lines is one of the most severe problems for flow assurance in the gas and oil industry. Developing effective kinetic hydrate inhibitors (KHIs) to avoid the problem of gas hydrate ... -
Genomics and transcriptomics yields a system-level view of the biology of the pathogen Naegleria fowleri
(Peer reviewed; Journal article, 2021)Background The opportunistic pathogen Naegleria fowleri establishes infection in the human brain, killing almost invariably within 2 weeks. The amoeba performs piece-meal ingestion, or trogocytosis, of brain material ... -
Network analysis of nitrate-sensitive oral microbiome reveals interactions with cognitive function and cardiovascular health across dietary interventions
(Peer reviewed; Journal article, 2021)Many oral bacteria reduce inorganic nitrate, a natural part of a vegetable-rich diet, into nitrite that acts as a precursor to nitric oxide, a regulator of vascular tone and neurotransmission. Aging is hallmarked by reduced ... -
A template to quantify the location and density of CD3 + and CD8 + tumor-infiltrating lymphocytes in colon cancer by digital pathology on whole slides for an objective, standardized immune score assessment
(Peer reviewed; Journal article, 2021)Background In colon cancer, the location and density of tumor-infiltrating lymphocytes (TILs) can classify patients into low and high-risk groups for prognostication. While a commercially available ‘Immunoscore®’ exists, ... -
Intrinsic Strand-Incision Activity of Human UNG: Implications for Nick Generation in Immunoglobulin Gene Diversification
