Organotellurium Reagents for Multiparametric Interrogation of Dynamic Biology
… cells have advanced understanding of innumerable biochemical processes and continue to be routinely used in the laboratory. Despite this success, PAMs are limited in their ability to report on the precise state of important individual members of a population. The recent emergence of mass cytometry …

Enabling Cl-Based bioconversion with metabolic engineering
… gas and methanol, are attractive feedstocks for biochemical processes, as they are widely available, can be produced renewably, and do not compete with food supply. However, their use in industrial bioprocessing remains limited, primarily because microbes that utilize these substrates are poorly …

In vivo steroid sensing using corona phase molecular recognition : design, synthesis, and applications
Steroid hormones dictate a number of underlying biochemical processes controlling human physiology and disease. Changes in steroid hormone concentration and activity are often either indicators or direct causes of disease. In the clinic, steroids are measured as biomarkers of health and have been …

Inhibition of Photosynthesis in Whole Tomato Plants Following Chilling in the Light: The Role of Enzymes of the Photosynthetic Carbon Reduction Cycle
… Under normal growing conditions, the component processes of whole plant photosynthesis appear to be balanced in such a way that it is unlikely that any single biochemical reaction is ever a sole limiting factor to photosynthesis or to growth. However, after a plant has been subjected to a …

Joint base-calling of two DNA sequences with factor graphs
… organisms and offering insights into complicated biochemical processes. DNA sequencing is a process encompassing both chemical reactions and signal processing techniques to identify the order of chemical bases in a DNA molecule. In this thesis, we focus on the base-calling stage, during which base …

Defining Multiple Steps in Human Telomere End Processing
Telomere overhangs are essential for chromosome end protection and telomerase extension, but how telomere overhangs are generated is unknown. Due to the classic end replication problem, leading DNA daughter strands are initially blunt while lagging daughters are shorter by at least the size of the …
