Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

tripleC: Communication, Capitalism & Critique, 2011 Any living cell parasitizing a host organism is immersed into a molecular environment of unfathomable complex- ity. For the advancement of its life cycle in such “hostile” a territory, the cell has to carefully sense its environment, “see” the ongoing ...

Evolving artificial cell signaling networks using molecular classifier systems [PDF]
, 2006 Nature is a source of inspiration for computational techniques which have been successfully applied to a wide variety of complex application domains. In keeping with this we examine Cell Signaling Networks (CSN) which are chemical networks responsible ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Comparison between TACS and CBTC System Degradation Impacts in Urban Rail Transit
Chengshi guidao jiaotong yanjiu[Objective] To meet increasing urban rail transit capacity demands, traditional CBTC (communication-based train control) signaling systems-with ground-based interlocking as core architecture-are evolving toward TACS (train autonomous circumnavigation ...

Circuitry of nuclear factor κB signaling [PDF]
, 2006 Over the past few years, the transcription factor nuclear factor (NF)-κB and the proteins that regulate it have emerged as a signaling system of pre-eminent importance in human physiology and in an increasing number of pathologies. While NF-κB is present
