Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land(More)

(1980). Adherence of bacteria to hydrocarbons: a simple method for measuring cell-surface hydrophobicity. Increased cell wall thickness and its effects on potential virulence properties of tetracycline-resistant Staphylococcus aureus. Induction of fibronectin-binding proteins and increased adhesion of quinolone-resistant Staphylococcus aureus by(More)
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a ubiquitous enzyme involved in glycolysis and shown, particularly in animal cells, to play additional roles in several unrelated non-metabolic processes such as control of gene expression and apoptosis. This functional versatility is regulated, in part at least, by redox post-translational modifications(More)
Reversible redox post-translational modifications such as oxido-reduction of disulfide bonds, S-nitrosylation, and S-glutathionylation, play a prominent role in the regulation of cell metabolism and signaling in all organisms. These modifications are mainly controlled by members of the thioredoxin and glutaredoxin families. Early studies in photosynthetic(More)
Protein S-glutathionylation, the reversible formation of a mixed-disulfide between glutathione and protein thiols, is involved in protection of protein cysteines from irreversible oxidation, but also in protein redox regulation. Recent studies have implicated S-glutathionylation as a cellular response to oxidative/nitrosative stress, likely playing an(More)
A specific signaling role for H(2)O(2) in Chlamydomonas reinhardtii was demonstrated by the definition of a promoter that specifically responded to this ROS. Expression of a nuclear-encoded reporter gene driven by this promoter was shown to depend not only on the level of exogenously added H(2)O(2) but also on light. In the dark, the induction of the(More)
A tetrodotoxin (TTX)-sensitive fast inward Ca2+ current (ICa,TTX) was recorded at physiological Ca2+ levels (2 mM) in human single atrial cells. The whole-cell patch-clamp method and Na(+)-free solutions (20-22 degrees C) were used. ICa,TTX depended upon extracellular Ca2+. It was prominent at rather negative test potentials (maximal peak amplitude at(More)
For over forty years, philosophers have struggled with the "paradox of fiction", which is the issue of how we can get emotionally involved with fictional characters and events. The few neuroscientific studies investigating the distinction between the processing of real and fictional entities have evidenced that midline cortical structures and lateral(More)
Several theoretical models stress the role of executive functions in emotion regulation (ER). However, most of the previous studies on ER employed explicit regulatory strategies that could have engaged executive functions, beyond regulatory processes per se. Recently, there has been renewed interest in implicit forms of ER, believed to be closer to(More)
