Modulation of the nanoscale motion rate of Candida albicans by X-rays

Sandor Kasas, María Inés Villalba

IntroductionPatients undergoing cancer treatment by radiation therapy commonly develop Candida albicans infections (candidiasis). Such infections are generally treated by antifungals that unfortunately also induce numerous secondary effects in the patient. ...

Single-Cell Optical Nanomotion of Candida albicans in Microwells for Rapid Antifungal Susceptibility Testing

Sandor Kasas, María Inés Villalba

Candida albicans is an emerging multidrug-resistant opportunistic pathogen representing an important source of invasive disease in humans and generating high healthcare costs worldwide. The development of a rapid and simple antifungal susceptibility test ( ...

The Dynamics of Single-Cell Nanomotion Behaviour of Saccharomyces cerevisiae in a Microfluidic Chip for Rapid Antifungal Susceptibility Testing

Sandor Kasas, María Inés Villalba

The fast emergence of multi-resistant pathogenic yeasts is caused by the extensive-and sometimes unnecessary-use of broad-spectrum antimicrobial drugs. To rationalise the use of broad-spectrum antifungals, it is essential to have a rapid and sensitive syst ...

High-content, arrayed compound screens with rhinovirus, influenza A virus and herpes simplex virus infections

Gerardo Turcatti, Fabien Kuttler

Viruses are genetically and structurally diverse, and outnumber cells by orders of magnitude. They can cause acute and chronic infections, suppress, or exacerbate immunity, or dysregulate survival and growth of cells. To identify chemical agents with pro- ...

The Drosophila Baramicin polypeptide gene protects against fungal infection

Bruno Lemaitre, Mark Austin Hanson, Alice Marra, Igor Iatsenko

The fruit fly Drosophila melanogaster combats microbial infection by producing a battery of effector peptides that are secreted into the haemolymph. Technical difficulties prevented the investigation of these short effector genes until the recent advent of ...

Microfabricated nanomotion detectors for rapid cells viability tests

Anton Malovichko

The widespread use of antibiotics and antifungal drugs has provoked an increasing number of multi-resistant bacteria and fungi. The emergence of multiresistance to antibiotics has been now recognized as a very serious public health issue. In order to targe ...

Yeast Nanometric Scale Oscillations Highlights Fibronectin Induced Changes in C. albicans

Giovanni Dietler, Sandor Kasas, Leonardo Venturelli, Anne-Céline Verenna Kohler

Yeast resistance to antifungal drugs is a major public health issue. Fungal adhesion onto the host mucosal surface is still a partially unknown phenomenon that is modulated by several actors among which fibronectin plays an important role. Targeting the ye ...

Organotin(IV) 4-(benzo[d][1,3]dioxol-5-ylmethyl)piperazine-1-carbodithioates: Synthesis, characterization and biological activities

Paul Joseph Dyson

A series of organotin(IV) derivatives R3SnL (1-3), R2SnLCl (4-6) and R2SnL2 (7-9) (where R = Me, Bu, Ph and L = 4-(benzo[d][1,3]dioxol-5-ylmethyl)piperazine-1-carbodithioate) were prepared from the reaction of 4-(benzo[d][1,3]dioxol-5-ylmethyl)piperazine-1 ...

Drug Repurposing Approach Identifies a Synergistic Drug Combination of an Antifungal Agent and an Experimental Organometallic Drug for Melanoma Treatment

Paul Joseph Dyson, Olivier Pierre Zava, Tina Riedel

By screening a drug library comprising FDA approved compounds, we discovered a potent interaction between the antifungal agent haloprogin and the experimental organometallic drug RAPTA-T, to synergistically induce cancer cell killing. The combination of th ...

Applying a Trojan Horse Strategy to Ruthenium Complexes in the Pursuit of Novel Antibacterial Agents

Paul Joseph Dyson, Lucinda Kate Batchelor

Siderophores are iron chelators secreted by bacteria to scavenge iron(III) from their surrounding environment. They possess their own internalization pathway that is sufficiently unselective to be hijacked, making them suitable for Trojan Horse strategy ap ...

Caspofungin on ARGET-ATRP grafted PHEMA polymers: Enhancement and selectivity of prevention of attachment of Candida albicans

Harm-Anton Klok, Piotr Mocny

There is a need for coatings for biomedical devices and implants that can prevent the attachment of fungal pathogens while allowing human cells and tissue to appose without cytotoxicity. Here, the authors study whether a poly(2-hydroxyethylmethacrylate) (P ...

Fungicidal activity of copper-sputtered flexible surfaces under dark and actinic light against azole-resistant Candida albicans and Candida glabrata

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

Candida spp. are able to survive on hospital surfaces and causes healthcare-associated infections (HCAIs). Since surface cleaning and disinfecting interventions are not totally effective to eliminate Candida spp., new approaches should be devised. Copper ( ...

Synthesis, structural elucidation and biological activities of organotin(IV) derivatives of 4-(2-thienyl)butyric acid

Paul Joseph Dyson

A series of tri- and diorganotin(IV) derivatives of 4-(2-thienyl)butyric acid have been synthesized by the reaction of ligand acid with tri- and diorganotin salts in 1:1 and 2:1 molar ratios, respectively. The synthesized compounds have been confirmed by C ...

Digital microfluidics for time-resolved cytotoxicity studies on single non-adherent yeast cells

Martinus Adela Maria Gijs, Matteo Cornaglia

Single cell analysis (SCA) has gained increased popularity for elucidating cellular heterogeneity at genomic, proteomic and cellular levels. Flow cytometry is considered as one of the most widely used techniques to characterize single cell responses; howev ...

Endocrine Disrupting Compounds Affecting Corticosteroid Signaling Pathways in Czech and Swiss Waters: Potential Impact on Fish

Kristin Schirmer

This study investigated the occurrence of corticosteroid signaling disruptors in wastewaters and rivers in the Czech Republic and in Switzerland. 36 target compounds were detected using HPLC-MS/MS, with up to 6.4 mu g/L for azole antifungals that indirectl ...

Detailed analysis and follow-up studies of a high-throughput screening for indoleamine 2,3-dioxygenase 1 (IDO1) inhibitors

Pierre Vogel, Gerardo Turcatti, Marc Chambon, Somi Reddy Majjigapu

Indoleamine 2,3-dioxygenase 1 (IDO1) is a key regulator of immune responses and therefore an important therapeutic target for the treatment of diseases that involve pathological immune escape, such as cancer. Here, we describe a robust and sensitive high-t ...
