Cellular pathways of carbon and nitrogen assimilation in kleptoplastic foraminiferal species

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Kleptoplasty is the process by which an organism sequesters algal chloroplasts while discarding or digesting other algal components. This ability is encountered in different organisms, including benthic foraminifera. Among kleptoplastic foraminiferal speci ...

Renal metabolism of hyperpolarized [1-13C]aspartate

Hikari Ananda Infinity Yoshihara

Aspartic acid is involved in several central metabolic pathways, including gluconeogenesis, the urea cycle, de novo nucleotide synthesis, the malate-aspartate shuttle, and via transmination the TCA cycle. The conversion in vivo of hyperpolarized [1-13C]pyr ...

Design of Surface-Supported Bio-inspired Networks for CO2 and O2 Activation at Room Temperature

Daniel Eduardo Hurtado Salinas

The structure of a biological system defines its function. Therefore, nature has developed sophisticated systems that catalyze chemical reactions that are vital for life on earth. For instance, the photosynthesis is a biological process that is partially r ...

A unique perspective of coral disease: Infection dynamics and metabolic interactions at the (sub-) cellular level

Anders Meibom, Isabelle Domart-Coulon, Emma Mary Gibbin, Louise Helene Soegaard Jensen

Global warming has triggered an increase in both prevalence and severity of coral disease outbreaks, yet little is known about the mechanism(s) by which coral disease functions, or what controls a corals’ susceptibility to infection. Failure to address suc ...

Quantitative Mass Spectrometry Reveals Plasticity of Metabolic Networks in Mycobacterium smegmatis

John McKinney, Romain Hamelin, Florence Armand, Diego Chiappe, Marc Moniatte, Tarun Chopra

Mycobacterium tuberculosis has a remarkable ability to persist within the human host as a clinically inapparent or chronically active infection. Fatty acids are thought to be an important carbon source used by the bacteria during long term infection. Catab ...

Fragmentation mechanism of UV-excited peptides in the gas phase

Thomas Rizzo, Michael Zachary Kamrath, Aleksandra Zabuga

We present evidence that following near-UV excitation, protonated tyrosine- or phenylalanine–containing peptides undergo intersystem crossing to produce a triplet species. This pathway competes with direct dissociation from the excited electronic state and ...

Dynamics of UV-excited, protonated peptides in the gas phase

Aleksandra Zabuga

The scope of this thesis is the electronically excited state dynamics of protonated peptides and their photofragmentation mechanism. UV radiation induces fragmentation of biological molecules and might cause various diseases, such as cataracts or skin canc ...

In vivo metabolic studies in skeletal and cardiac muscle using ¹³C magnetic resonance spectroscopy

Josefina Adriana Maria Bastiaansen

Cardiac and skeletal muscle function relies on a continuous energy production via fatty acid metabolism and mitochondrial oxidation of pyruvate, with a fine balance between substrate delivery and utilization. Changes in metabolism are increasingly being im ...

Quantum dynamics study of the competing ultrafast intersystem crossing and internal conversion in the "channel 3" region of benzene

Thomas James Penfold

Time-resolved photoelectron spectroscopy can obtain detailed information about the dynamics of a chemical process on the femtosecond timescale. The resulting signal from such detailed experiments is often difficult to analyze and therefore theoretical calc ...

Photoelectrochemical complexes for solar energy conversion that chemically and autonomously regenerate

Ardemis Anoush Boghossian

Naturally occurring photosynthetic systems use elaborate pathways of self-repair to limit the impact of photo-damage. Here, we demonstrate a complex consisting of two recombinant proteins, phospholipids and a carbon nanotube that mimics this process. The c ...
