[The stringent response--bacterial mechanism of an adaptive stress response].

Postepy biochemii, 2006
The stringent response is a key regulatory reaction exhibited by bacteria in response to amino acid deprivation or carbon, nitrogen and phosphate limitation. In E. coli, the products of the relA and spoT genes regulate accumulation of the effector molecules of the stringent response--guanosine tetra- and pentaphosphates (ppGpp and pppGpp respectively).

Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

Advanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Selective Benzene Capture by Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

Advanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Random walks in the stringent response

, 2016
The stringent response plays key role in the activation and regulation of the adaptive mechanisms that bacteria employ in order to accommodate to the adverse conditions. In E.coli the process is governed by the stringent factor RelA, transferring the amino-acid starvation signals by synthesize (p)ppGpp altering cell replication, transcription and ...

Genetic components of stringent response in Vibrio cholerae.

The Indian journal of medical research, 2011
Nutritional stress elicits stringent response in bacteria involving modulation of expression of several genes. This is mainly triggered by the intracellular accumulation of two small molecules, namely, guanosine 3'-diphosphate 5'-triphosphate and guanosine 3',5'-bis(diphosphate), collectively called (p)ppGpp.
