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.

IMAGES DISTRIBUTION OF BINARY SYMMETRICAL GRAVITATIONAL LENS

Odessa Astronomical Publications, 2019
In this paper, we study the distribu- tion of images from a point source in N - point gravi- tational lenses. It is well known that in a Schwarzschild lens (N = 1) from a point source, there are always two images.

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)

Caustic Ingestion in Children in South of Iran: A Two-Year Single Center Study

Middle East Journal of Digestive Diseases, 2018
BACKGROUND Caustic ingestion is one of the most important injuries during childhood, which leads to serious sequel. In this study, we evaluated the clinical manifestations, endoscopic appearance, complications, and treatment results in patients with ...

OGLE-2013-BLG-0578L: Microlensing Binary Composed of A Brown Dwarf And An M Dwarf

, 2015
Determining physical parameters of binary microlenses is hampered by the lack of information about the angular Einstein radius due to the difficulty of resolving caustic crossings.

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 ...

Caustics Formation by a Spherical Reflector – Geometric and Wave Field Analysis with Applications in Room Acoustics and Radio Astronomy

Engineering Transactions
Based on the principles of geometrical optics, an analytical description of caustics generated in a spherical mirror is presented. The formation of caustics in a wave field is studied using acoustic and electromagnetic waves as an example.

Effect of caustic soda on the intensity of gassing in the production of non-autoclaved aerated concrete

MATEC Web of Conferences, 2017
This article discusses the effect of caustic soda on the intensity of gassing in the production of non-autoclaved aerated concrete. It has been found out that adding 0.8 and 1.0 percent of caustic soda increases the amount of released hydrogen by 20-40%.

Caustic design in periodic lattices [PDF]

, 2012
We study curved trajectory dynamics and design in discrete array settings. We find that beams with power law phases produce curved caustics associated with the fold and cusp type catastrophes.
