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.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Measuring the health effects of air pollution : to what extent can we really say people are dying from bad air? [PDF]

, 2004
Estimation of the effects of environmental impacts is a major focus of current theoretical and policy research in environmental economics. Such estimates are used to set regulatory standards for pollution exposure; design appropriate environmental ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

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 ...

Environmental Changes and Effects on a Population of Smooth Newt Lissotriton meridionalis (Boulenger, 1882) (Amphibia, Urodela) in a Mediterranean Woodland [PDF]

, 2017
The population of Lissotriton meridionalis in the area of “Bosco di Palo” Natural Park are monitored since 1995. From 2004 to 2005 in the area it was carried out a massive cutting of dead trees with evidence of alteration of the undergrowth.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Corrections to “Secrecy Outage Analysis for Distributed Antenna Systems in Heterogeneous Cellular Networks”

IEEE Access, 2019
In [1], the calculation of (8) was erroneous. To be specific, as shown in (8) of [1], the average transmit power of a specially-designed signal ${x_{m} = - {{\sqrt {P_{S}} {h_{Sm}}h_{Am}^{*}{x_{S}}}}/{{{{\left |{ {{h_{Am}}} }\right |}^{2}}}}}$ was ...
