Classical and alternative complement pathway activation by pneumococci [PDF]
Infection and Immunity, 1977 Sixty-two strains of Streptococcus pneumoniae were studied for their abilities to consume selected components of classical and alternative complement pathways in human sera. The classical pathway was blocked by chelating calcium with ethyleneglycol-bios (beta-aminoethyl ether)-N,N-tetraacetic acid and by removing C4. The alternative pathway was blocked

FEBS Letters, EarlyView.Single‐cell RNA sequencing reveals an opposite role of SLPI in basal tumors based on metastatic spread, along with shared activation of specific regulons in cancer cells and mature luminal lactocytes, as well as downregulation of MALAT1 and NEAT1 in the latter.

A Quantum Computer Architecture using Nonlocal Interactions [PDF]
, 2003 Several authors have described the basic requirements essential to build a scalable quantum computer. Because many physical implementation schemes for quantum computing rely on nearest neighbor interactions, there is a hidden quantum communication ...

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.

A New Tool for Complement Research: In vitro Reconstituted Human Classical Complement Pathway
Frontiers in Immunology, 2018 The complement, as part of the innate immune system, represents the first line of defense against Gram-negative bacteria invading the bloodstream. The complement system is a zymogen cascade that ultimately assemble into the so-called membrane attack ...

Cancer Medicine, 2021 Background The introduction of multiparametric magnetic resonance imaging (mpMRI) and MRI‐guided biopsy has improved the diagnosis of prostate cancer. However, it remains uncertain whether it is cost‐effective, especially in a population‐based screening ...

The phylogeny of the complement system and the origins of the classical pathway
Immunobiology, 2007 The origins of the complement system have now been traced to near to the beginnings of multi-cellular animal life. Most of the evidence points to the earliest activation mechanism having been more similar to the lectin pathway than to the alternative pathway.

Observing classical nucleation theory at work by monitoring phase transitions with molecular precision. [PDF]
, 2014 It is widely accepted that many phase transitions do not follow nucleation pathways as envisaged by the classical nucleation theory. Many substances can traverse intermediate states before arriving at the stable phase. The apparent ubiquity of multi-step

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 ...
