Mitochondrial stress signalling and its impacts on physiology

Mitochondria are responsible for respiration and energy harvesting across the eukaryotic kingdom. They also take part in other cellular processes like intermediary metabolism. As a result, mitochondrial function directly impacts organismal features such as ...

More Medicines for Tuberculosis: Fuelling Drug Discovery against Mycobacterium tuberculosis

Shi-Yan Caroline Foo

Tuberculosis (TB), whose etiological agent is Mycobacterium tuberculosis (M. tuberculosis), has plagued humanity since antiquity. Even with chemotherapy available today, TB is the leading cause of death due to an infectious disease. Modern day factors, suc ...

Mechanisms of the Antibacterial Effects of TiO2-FeOx under Solar or Visible Light: Schottky Barriers versus Surface Plasmon Resonance

Juan Kiwi, Sami Rtimi

This study reports the significant mechanistic difference between binary-oxide antibacterial films with the same composition but different microstructures. Binary TiO2-FeOx films were found to present a faster bacterial inactivation kinetics under visible ...

The potential impact of case-area targeted interventions in response to cholera outbreaks: A modeling study

Andrea Rinaldo, Enrico Bertuzzo, Flavio Finger

Background Cholera prevention and control interventions targeted to neighbors of cholera cases (case-area targeted interventions [CATIs]), including improved water, sanitation, and hygiene, oral cholera vaccine (OCV), and prophylactic antibiotics, may be a ...

Solar photo-Fenton disinfection of 11 antibiotic-resistant bacteria (ARB) and elimination of representative AR genes. Evidence that antibiotic resistance does not imply resistance to oxidative treatment

César Pulgarin, Stefanos Giannakis, Truong-Thien Melvin Le

The emergence of antibiotic resistance represents a major threat to human health. In this work we investigated the elimination of antibiotic resistant bacteria (ARB) by solar light and solar photo-Fenton processes. As such, we have designed an experimental ...

Nanomechanical sensor applied to blood culture pellets: a fast approach to determine the antibiotic susceptibility against agents of bloodstream infections

Giovanni Dietler, Sandor Kasas, Giovanni Longo, Petar Stupar

Objectives: The management of bloodstream infection, a life-threatening disease, largely relies on early detection of infecting microorganisms and accurate determination of their antibiotic susceptibility to reduce both mortality and morbidity. Recently we ...

A Microfluidic Platform Enables Large-Scale Single-Cell Screening to Identify Genes Involved in Bacterial Persistence

Amanda Verpoorte

Persistent cells, representing a small fraction of a bacterial population, are refractory to antibiotic therapy. It is a phenotypic transient state. The underlying mechanisms of persistence remain largely unknown, but even divergent hypotheses agree on a f ...

Tetracyclines Disturb Mitochondrial Function across Eukaryotic Models: A Call for Caution in Biomedical Research

Johan Auwerx, Bart Deplancke, Richardus Houtkooper, Laurent Mouchiroud, Dongryeol Ryu, Xu Wang, Evan Graehl Williams, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite, Norman Lionel Moullan, Michael Vincent Frochaux

In recent years, tetracyclines, such as doxycycline, have become broadly used to control gene expression by virtue of the Tet-on/Tet-off systems. However, the wide range of direct effects of tetracycline use has not been fully appreciated. We show here tha ...
