Inter- and intra-individual variability in CO2 production and metabolic rate

Carbon dioxide generated by the human body and exhaled (VCO2) is commonly used for ventilation controls, while the metabolic rate (i.e., energy expenditure EE) is an important parameter defining human thermal comfort in buildings. These two parameters are ...

Quantitative modeling of human metabolism: A call for a community effort

Vassily Hatzimanikatis, Maria Masid Barcon

Metabolism is the process by which cells and organisms obtain nutrients and energy to perform their functions. In the last years, many human diseases, including cancer, diabetes, and cardiac diseases, have been associated with altered metabolism. Understan ...

Modeling, predicting and mining metabolism at atom-level resolution

Jasmin Maria Hafner

Living organisms can catalyze many thousands of biochemical reactions that they use to convert energy and matter, which provides them with the essentials for life. The sum of these chemical reactions happening in an organism is called metabo-lism. Understa ...

Modeling metabolic and signaling pathways in cancer cells

Maria Masid Barcon

Cancer is a leading cause of death in the world, and the mechanisms that underlie this disease are still not completely understood. As cancer develops and progresses, cells undergo a diversity of mutations that sustain their rapid proliferation and the eva ...

Analysis of human metabolism by reducing the complexity of the genome-scale models using redHUMAN

Vassily Hatzimanikatis, Meriç Ataman, Maria Masid Barcon

Altered metabolism is associated with many human diseases. Human genome-scale metabolic models (GEMs) were reconstructed within systems biology to study the biochemistry occurring in human cells. However, the complexity of these networks hinders a consiste ...

Towards comprehensive and consistent kinetic models of metabolism under uncertainty

Tuure Eelis Hameri

Metabolism is the sum of the chemical interactions occurring inside a cell that process nutrients into cellular constituents and energy. Research in the recent decades has enabled the characterization of metabolic reaction networks for multiple organisms. ...

Circadian Rhythms and Mitochondria: Connecting the Dots

Carlos Canto Alvarez, Miriam Valera Alberni

Circadian rhythms provide a selective advantage by anticipating organismal nutrient needs and guaranteeing optimal metabolic capacity during active hours. Impairment of circadian rhythms is associated with increased risk of type 2 diabetes and emerging evi ...

Role of ACMSD in regulation of NAD+ metabolism and mitochondrial function

Elena Katsyuba

Discovered in the beginning of the 20th century, nicotinamide adenine dinucleotide (NAD+) has evolved from a simple oxidoreductase cofactor to being an essential cosubstrate for a wide range of regulatory proteins that include most notoriously the sirtuin ...

The antioxidant capacity of erythrocyte concentrates is increased during the first week of storage and correlated with the uric acid level

Hubert Girault, Michel Prudent, Niels Erik Lion, Fernando Cortes Salazar, Manon Sandra Bardyn, Sunny Isaïe Maye, Andreas Stephan Lesch

Background and Objectives: Red blood cells (RBCs) suffer from lesions during cold storage, depending in part on their ability to counterbalance oxidative stress by activating their antioxidant defence. The aim of this study was to monitor the antioxidant p ...

Compartmentalised energy metabolism supporting glutamatergic neurotransmission in response to increased activity in the rat cerebral cortex: A 13C MRS study in vivo at 14.1 T

Rolf Gruetter, João Miguel das Neves Duarte, Nathalie Just, Sarah Catherine Sonnay

Many tissues exhibit metabolic compartmentation. In the brain, while there is no doubt on the importance of functional compartmentation between neurons and glial cells, there is still debate on the specific regulation of pathways of energy metabolism at di ...
