Self-similar dynamics of bacterial chemotaxis

, 2012
Colonies of bacteria grown on thin agar plate exhibit fractal patterns as a result of adaptation to their environments. The bacterial colony pattern formation is regulated crucially by chemotaxis, the movement of cells along a chemical concentration ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Discovery of the widespread site-specific single-stranded nuclease family Ssn

Nature Communications
Site-specific endonucleases that exclusively cut single-stranded DNA have hitherto never been described and constitute a barrier to the development of ssDNA-based technologies.

Continuous watermelon cropping impairs plant growth by modifying soil biochemistry and rhizosphere microbial communities

Frontiers in Microbiology
Continuous watermelon cropping leads to increases in soil-borne diseases, which negatively affect plant growth. We investigated the impact of continuous watermelon cropping on soil biochemical properties, enzyme activities, microbial biomass, occurrence ...

Comprehensive Evaluation of the MBT STAR-BL Module for Simultaneous Bacterial Identification and β-Lactamase-Mediated Resistance Detection in Gram-Negative Rods from Cultured Isolates and Positive Blood Cultures

Frontiers in Microbiology, 2018
Objective: This study evaluated the capability of a MALDI Biotyper system equipped with the newly introduced MBT STAR-BL module to simultaneously perform species identification and β-lactamase-mediated resistance detection in bacteremia -causing bacteria

Variation in bacterial populations in time and space [PDF]

, 1977
Obtaining a reliable estimate of the bacterial population is one of the main problems facing the bacterial ecologist. The author discusses the various methods available and concludes that the observed variability in bacterial populations depends on the ...

Microbial and metabolic succession on common building materials under high humidity conditions. [PDF]

, 2019
Despite considerable efforts to characterize the microbial ecology of the built environment, the metabolic mechanisms underpinning microbial colonization and successional dynamics remain unclear, particularly at high moisture conditions. Here, we applied

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Synthesis and Estimation of the Insecticide and Antibacterial Activities for Some New Amide Derivatives

Indonesian Journal of Chemistry, 2023
In this work, new compounds of amide derivatives (C1-C3) were synthesized through the conversion reaction of p-chloroaniline to diazonium salt (B1), which reacts with aniline to form a new azo-compound (B3).
