Journal of Raman Spectroscopy, EarlyView.We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage
Viruses, 2013 In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of

Diversity and Host Interactions among Virulent and Temperate Baltic Sea Flavobacterium Phages
Viruses, 2020 Viruses in aquatic environments play a key role in microbial population dynamics and nutrient cycling. In particular, bacteria of the phylum Bacteriodetes are known to participate in recycling algal blooms.

Transient-mediated fate determination in a transcriptional circuit of HIV [PDF]
, 2007 Steady-state behavior and bistability have been proposed as mechanisms for decision-making in gene circuits. However, transient gene expression has also been proposed to control cell fate with the decision arbitrated by the lifetime of the expression ...

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm
Macromolecular Rapid Communications, EarlyView.Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Nihon Chikusan Gakkaiho, 1980 Lactic streptococciおよびlactobacilliの溶原性についていくつかの報告が行われているが,leuconostoc菌種の溶原性についての報告は,著者らが知るかぎりにおいて見い出せない.本報告は,leuconostoc菌種の溶原性の検索を目的としleuconostoc 32菌株をマイトマイシンC処理により,その溶原性の有無を調べた.Leuconostoc菌株の溶原性のマイトマイシンCによる誘発は,その濃度に大きく依存しまたマイトマイシンCに対する感受性は,leuconostoc菌株によってことなった.Leuconostoc菌株を培養し対数期初期にマイトマイシンCを液体培地1ml当り最終濃度0.5μgおよび5.0μg加えて溶原菌株の誘発を行った.Leuconostoc ...

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction
PROTEOMICS, EarlyView.ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Sampling rare switching events in biochemical networks
, 2004 Bistable biochemical switches are ubiquitous in gene regulatory networks and signal transduction pathways. Their switching dynamics, however, are difficult to study directly in experiments or conventional computer simulations, because switching events ...

Cell aging preserves cellular immortality in the presence of lethal levels of damage. [PDF]
, 2019 Cellular aging, a progressive functional decline driven by damage accumulation, often culminates in the mortality of a cell lineage. Certain lineages, however, are able to sustain long-lasting immortality, as prominently exemplified by stem cells.

Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing
Small, EarlyView.Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...
