Isabel González-Mariscal, Elena García-Testón, Sergio Padilla, Alejandro Martín-Montalvo, Teresa Pomares Viciana, Luis Vazquez-Fonseca, Pablo Gandolfo Domínguez, Carlos Santos-Ocaña
2014 Molecular Syndromology  
In general, the induction of COQ gene expression produced by metabolic changes or stress is modulated downstream by other regulatory mechanisms such as the protein import to mitochondria, the assembly  ...  The activity of Coq8p, probably as kinase, allows the formation of an initial pre-complex containing all Coq proteins with the exception of Coq7p.  ...  Spanish Ministerio de Ciencia y Tecnología, Spanish PI11/00078, Junta de Andalucía P08-CTS-03988 and by the International Q 10 Association 'Phosphorylation based regulation of coenzyme Q biosynthesis in  ...

ESR and monolayer study of the localization of coenzyme Q10 in artificial membranes

M Grzybek, K Stebelska, P Wyrozumska, P Grieb, M Langner, A Jaszewski, A Jezierski, A F Sikorski
2005 General Physiology and Biophysics  
The presence of CoQ10 in the hydrophobic core has further implications on the properties of membrane intrinsic domain.  ...  The data obtained from the ESR experiments show a complex, depth dependent effect of CoQ10 on the lipid molecules mobility in the bilayer.  ...  We conclude therefore that, in DMPC and DPPC monolayers, CoQ 10 molecules are probably organized in some kind of clusters (probably with their tails interacting together laying over the shorter tails of  ...

Formalization of Quantum Protocols using Coq

Jaap Boender, Florian Kammüller, Rajagopal Nagarajan
2015 Electronic Proceedings in Theoretical Computer Science  
We provide a Coq library for quantum bits (qubits), quantum gates, and quantum measurement.  ...  The building of practical, general purpose Quantum Computers may be some years into the future. However, Quantum Communication and Quantum Cryptography are well developed.  ...  Future work will aim to look at simplifying some definitions, improving the specifications and enhancing the general readability of the Coq code.  ...

Genetic bases and clinical manifestations of coenzyme Q10 (CoQ10) deficiency

Maria Andrea Desbats, Giada Lunardi, Mara Doimo, Eva Trevisson, Leonardo Salviati
2014 Journal of Inherited Metabolic Disease  
Coenzyme Q 10 is a remarkable lipid involved in many cellular processes such as energy production through the mitochondrial respiratory chain (RC), beta-oxidation of fatty acids, and pyrimidine biosynthesis  ...  of the CoQ 10 biosynthetic complex, increased degradation of CoQ 10 or a general impairment of mitochondrial function.  ...  The antioxidant effect of CoQ 10 is probably highly relevant, in fact renal involvement correlates with increased ROS production in this tissue (Quinzii et al 2013) .  ...

Automatically Proving Mathematical Theorems with Evolutionary Algorithms and Proof Assistants [article]

Li-An Yang, Jui-Pin Liu, Chao-Hong Chen, Ying-ping Chen
2016 arXiv   pre-print
Ten simple theorems from various branches of mathematics were proven, and most of these theorems cannot be proven by using the tactic auto alone in Coq, the adopted proof assistant.  ...  Thanks to the transformation from logic to computation, it is now possible to generate or search for formal proofs directly in the realm of computation.  ...  ACKNOWLEDGMENTS The work was supported in part by the Ministry of Science and Technology of Taiwan under Grant MOST 104-2221-E-009-126.  ...

Certifying the True Error: Machine Learning in Coq with Verified Generalization Guarantees

Alexander Bagnall, Gordon Stewart
2019 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
MLCERT is practical in that we extract learning procedures defined in Coq to executable code; thus procedures with proved generalization bounds can be trained and deployed in real systems.  ...  MLCERT is mechanized in that we prove generalization bounds inside the theorem prover Coq; thus the bounds are machine checked by Coq's proof checker.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the NSF or of OFRN.  ...

Position Paper: Thoughts on Programming with Proof Assistants

Adam Chlipala
2007 Electronical Notes in Theoretical Computer Science  
My purpose in this position paper is to make the general claim that Coq is already quite useful today for non-trivial certified programming tasks, as well as to highlight some reasons why you might want  ...  to consider using it as a base for your next project in dependently-typed programming.  ...  The auto tactic probably generates proof terms that aren't as nice to read as those I've used here.  ...

Metabolism and function of coenzyme Q

Mikael Turunen, Jerker Olsson, Gustav Dallner
2004 Biochimica et Biophysica Acta - Biomembranes  
The biosynthesis of CoQ is studied in great detail in bacteria and yeast but only to a limited extent in animal tissues and therefore the informations available is restricted.  ...  Coenzyme Q (CoQ) is present in all cells and membranes and in addition to be a member of the mitochondrial respiratory chain it has also several other functions of great importance for the cellular metabolism  ...  Species difference is probably a deciding factor as in mice dietary CoQ appear in various organs [231] .  ...

Cost of Quality in Crowdsourcing

Deniz Iren, Semih Bilgen
2014 Human Computation  
A well-defined methodology is needed to estimate these impacts in order to manage the crowdsourcing process effectively and efficiently.  ...  However, due to loose worker-employer relationships, skill diversity of the crowd and anonymity of participants, it tends to result in lower quality compared to traditional ways of doing work.  ...  CoQ Calculations Probability values in Table 6 are used for CoQ calculations.  ...

2021 Animal Reproduction  
For cryopreservation, each ejaculate was divided in three treatments: 1) Botucrio® diluent (control); 2) 50 μmol CoQ-10 added to Botucrio® diluent; 3) 1 mmol CoQ-10 added to Botucrio® diluent.  ...  It was concluded that the addition of 1 mmol CoQ-10 to the freezing diluent was more effective in preserving mitochondria functionality and cytoskeleton of sperm cells submitted to cryopreservation process  ...  , and a spermatozoon without energy or in oxidative stress, probably will not be successful in fertilization.  ...

Due to these two actions, CoQ 10 is commonly used in clinical practice in chronic heart failure, male infertility, and neurodegenerative disease.  ...  Coenzyme Q 10 (CoQ 10 ), also known as ubiquinone for its presence in all body cells, is an essential part of the cell energy-producing system.  ...  Growth hormone probably influences CoQ 10 consumption, due to accelerated metabolism, as in the case of hyperthyroidism.  ...
