Socioeconomic development predicts a weaker contraceptive effect of breastfeeding

The contraceptive effect of breastfeeding remains essential to controlling fertility in many developing regions of the world. The extent to which this negative effect of breastfeeding on ovarian activity is sensitive to ecological conditions, notably mater ...

Multimodal Response to Copper Binding in Superoxide Dismutase Dynamics

David Lyndon Emsley

Copper/zinc superoxide dismutase (SOD) is a homodimeric metalloenzyme that has been extensively studied as a benchmark for structure-function relationships in proteins, in particular because of its implication in the familial form of the neurodegenerative ...

C/EBP alpha mediates the growth inhibitory effect of progestins on breast cancer cells

Cathrin Brisken, Valentina Scabia

Steroid hormones are key gene regulators in breast cancer cells. While estrogens stimulate cell proliferation, progestins activate a single cell cycle followed by proliferation arrest. Here, we use biochemical and genome-wide approaches to show that proges ...

A high resolution LC-MS targeted method for the concomitant analysis of 11 contraceptive progestins and 4 steroids

Cathrin Brisken, Jonathan Paz Montoya, Marc Moniatte, Fabio De Martino, Marie Shamseddin, Csaba Ferenc László, Alexandre Béguin

In the context of hormonal contraception and hormone replacement therapy (HRT), many women are exposed to exogenous hormones. Current use of hormonal contraception with combined ethinyl estradiol and different progestins bestows a breast cancer relative ri ...

Sex-specific changes in gene expression in response to estrogen pollution around the onset of sex differentiation in grayling (Salmonidae)

Oliver Michele Selmoni

The synthetic 17 alpha-ethinylestradiol (EE2) is a common estrogenic pollutant that has been suspected to affect the demography of river-dwelling salmonids. One possibility is that exposure to EE2 tips the balance during initial steps of sex differentiatio ...

Wastewater and green waste biorefinery Degradation of simple sugars using mixed cultures of purple non-sulfur bacteria: an insight into microbial interactions

Guillaume Crosset-Perrotin

Purple non-sulfur bacteria (PNSB) are phototrophic organisms that have raised interest for both industrial and domestic wastewater treatment and valorization because of their very high assimilation (~1 g CODX g-1 COD substrate) and valuable compounds produ ...

Diffusion-weighted MRS of acetate in the rat brain

Rolf Gruetter, Bernard Lanz, Hikari Ananda Infinity Yoshihara, Nicolas Kunz, Masoumeh Dehghani Moghadam

Acetate has been proposed as an astrocyte-specific energy substrate for metabolic studies in the brain. The determination of the relative contribution of the intracellular and extracellular compartments to the acetate signal using diffusion-weighted magnet ...

Polyphenic trait promotes liver cancer in a model of epigenetic instability

Didier Trono, Evaristo Jose Planet Letschert, Sandra Eloise Kjeldsen, Alessandra Piersigilli, Marco Cassano, Suk Min Jang

Hepatocellular carcinoma (HCC) represents the fifth most common form of cancer worldwide and carries a high mortality rate due to lack of effective treatment. Males are eight times more likely to develop HCC than females, an effect largely driven by sex ho ...

Proton diffusion spectroscopy and modeling of brain metabolism at 14.1T

Masoumeh Dehghani Moghadam

As a field at the CIBM, Nuclear magnetic resonance (NMR)spectroscopy can be applied non-invasively to explore the metabolic fate of energy fuel substrates, as well as the rate at which they are consumed, using 13C and 1H nuclei. The work of this thesis enc ...

Direct noninvasive estimation of myocardial tricarboxylic acid cycle flux in vivo using hyperpolarized 13C magnetic resonance

Rolf Gruetter, Hongxia Lei, Tian Cheng, Arnaud Comment, Josefina Adriana Maria Bastiaansen

BACKGROUND: The heart relies on continuous energy production and imbalances herein impair cardiac function directly. The tricarboxylic acid (TCA) cycle is the primary means of energy generation in the healthy myocardium, but direct noninvasive quantificati ...
