Analysis of cellular and drug action mechanisms in the malaria parasites using systems biology approaches

Anush Chiappino-Pepe

Malaria puts at risk of infection half of the world population and still kills around half a million people every year. The rapid and worrisome rise of drug-resistant malaria parasites hinders the treatment of malaria and calls for a global collaboration t ...

Recent Advances of Malaria Parasites Detection Systems Based on Mathematical Morphology

Michel Kocher

Malaria is an epidemic health disease and a rapid, accurate diagnosis is necessary for proper intervention. Generally, pathologists visually examine blood stained slides for malaria diagnosis. Nevertheless, this kind of visual inspection is subjective, err ...

Microfluidic high-content phenotypic screening on a Caenorhabditis elegans model

Maria Cristina Letizia

Caenorhabditis elegans is a performant model system for studying human biological processes and diseases and for pre-clinical phenotyping screenings of compounds. Microfluidics has been instrumental in enabling C. elegans-based drug assays, facilitating th ...

A design of experiment approach for efficient multi-parametric drug testing using a Caenorhabditis elegans model

Martinus Adela Maria Gijs, Matteo Cornaglia, Raphaël Etienne Jean Trouillon, Maria Cristina Letizia

When studying the drug effectiveness towards a target model, one should distinguish the effects of the drug itself and of all the other factors that could influence the screening outcome. This comprehensive knowledge is crucial, especially when model organ ...

Bioenergetics-based modeling of Plasmodium falciparum metabolism reveals its essential genes, nutritional requirements, and thermodynamic bottlenecks

Vassily Hatzimanikatis, Meriç Ataman, Anush Chiappino-Pepe, Stepan Tymoshenko

Novel antimalarial therapies are urgently needed for the fight against drug-resistant para- sites. The metabolism of malaria parasites in infected cells is an attractive source of drug targets but is rather complex. Computational methods can handle this co ...

Vector Control in Developing Countries: Challenges and Solutions

Michael Graetzel, Paul Joseph Dyson, Claire Samantha Allardyce

Undoubtedly, reducing vector populations or their interactions with hosts below a critical level is a practical and proven method of disease control. Introduction of insecticide-treated bed nets has significantly reduced malaria in some parts of the world. ...

Optimization of drug combinations using Feedback System Control

Paul Joseph Dyson, Hubert van den Bergh, Patrycja Nowak-Sliwinska, Andrea Brett Gasser

We describe a protocol for the discovery of synergistic drug combinations for the treatment of disease. Synergistic drug combinations lead to the use of drugs at lower doses, which reduces side effects and can potentially lead to reduced drug resistance, w ...
