The solar chemical composition [PDF]

Nuclear Physics A, 2006
We review our current knowledge of the solar chemical composition as determined from photospheric absorption lines. In particular we describe the recent significant revisions of the solar abundances as a result of the application of a time-dependent, 3D hydrodynamical model of the solar atmosphere instead of 1D hydrostatic models.

CHEMICAL COMPOSITION OF ROOT CHICORY

Овощи России, 2019
The value of the root chicory is due to the unique chemical composition of its roots. Depending on the variety, place of growth and growing conditions of culture chicory roots contain 72.0-77.0% water, 1.0-1.2% protein, 0.1-0.3% fat, 1.0-6.0% sugar, 12.0-

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.

Fundamental Parameters and Chemical Composition of Arcturus

, 2011
We derive a self-consistent set of atmospheric parameters and abundances of 17 elements for the red giant star Arcturus: Teff = 4286+/-30 K, logg = 1.66+/-0.05, and [Fe/H] = -0.52+/-0.04.

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)

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 ...

THE CHEMICAL COMPOSITION OF PROCYON

Odessa Astronomical Publications, 2017
The review of last studies on the chemical composition of Procyon showed that the abundances of 55 elements were investigated in the atmosphere of Procyon. The abundances of majority of elements are near Solar systems values. The exceptions are Li, Be, B,
