Imaging the emergence of bacterial turbulence: phase diagram and transition kinetics [PDF]

arXiv, 2020
We experimentally study the emergence of collective bacterial swimming, a phenomenon often referred to as bacterial turbulence. A phase diagram of the flow of 3D E. coli suspensions spanned by bacterial concentration, the swimming speed of bacteria and the number fraction of active swimmers is systematically mapped, which shows quantitative agreement ...

Simulated Media for Mimicking the Human Environment In Vitro

APMIS, Volume 133, Issue 4, April 2025.
ABSTRACT The phrase ‘All models are wrong but some are useful’ spoken by George Box in 1976 is as relevant today as ever. Modern research relies heavily on models and the use of in vitro models is the cornerstone of developing novel treatments for various infectious diseases.

Exogenous fatty acids inhibit fatty acid synthesis by competing with endogenously generated substrates for phospholipid synthesis in Escherichia coli

FEBS Letters, Volume 599, Issue 5, Page 667-681, March 2025.
Bacteria can absorb external fatty acids to build their membranes. Working in E. coli, we show that external fatty acids inhibit internal fatty acid production through competition for membrane synthesis. This rapid negative feedback helps bacteria conserve resources and preserve membrane properties. We predict similar mechanisms exist in many bacteria.

Prevalence of sexually transmitted infections and bacterial vaginosis among women in sub-Saharan Africa: An individual participant data meta-analysis of 18 HIV prevention studies

PLoS Medicine, 2018
Background Estimates of sexually transmitted infection (STI) prevalence are essential for efforts to prevent and control STIs. Few large STI prevalence studies exist, especially for low- and middle-income countries (LMICs).

Aspartate Metabolism‐Driven Gut Microbiota Dynamics and RIP‐Dependent Mitochondrial Function Counteract Oxidative Stress

Advanced Science, Volume 12, Issue 11, March 20, 2025.
This study examines the role of aspartate (Asp) metabolism in regulating gut microbiota and oxidative stress in piglets. Through interaction with the RIP1‐RIP3‐MLKL and RIP1‐Nrf2‐NF‐κB signaling pathways, Asp improves mitochondrial function and enhances the production of the antioxidant eicosapentaenoic acid (EPA), counteracting oxidative stress ...
