Control of pili synthesis and putrescine homeostasis in Escherichia coli

eLife
Polyamines are biologically ubiquitous cations that bind to nucleic acids, ribosomes, and phospholipids and, thereby, modulate numerous processes, including surface motility in Escherichia coli.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Plants back: Re‐envisioning botanical garden collections management for indigenous crops

PLANTS, PEOPLE, PLANET, EarlyView.
Botanical gardens and other ex situ collections play a key role in preventing plant extinctions, yet the needs of Indigenous crop cultivars are not being met by conventional botanical collections management practices. Inspired by Indigenous land care restoration movements centering plant–human–society relationships, we propose a path toward reciprocal ...

Structural basis of host recognition and biofilm formation by Salmonella Saf pili

eLife, 2017
Pili are critical in host recognition, colonization and biofilm formation during bacterial infection. Here, we report the crystal structures of SafD-dsc and SafD-SafA-SafA (SafDAA-dsc) in Saf pili.

The Hare and the Tortoise in Ecological L2 Learning: Distributed Practice Effects in Vocabulary and Grammar

TESOL Quarterly, EarlyView.
Abstract Research on the distributed practice effect, that is the impact of different intervals between learning sessions, has investigated both intentional and incidental learning of second language vocabulary and grammar targets. This research is complex and has produced conflicting findings: whereas robust effects have been shown for intentional ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
