BUFFER SYSTEMS OF THE BODY

open access: yesАктуальные проблемы теоретической и клинической медицины, 2022
A large number of acidic foods is formed in the human body during the metabolism during the day. The main products of metabolism in the cell are acids that dissociate with the release of [H+] ions, but due to buffer systems, acidification of the ...

Über ein aus menschlichen und tierischen Geweben isoliertes Nucleoproteins mit Kollagen-fällenden Eigenschaften. 2. Die Kollagen-fällenden Eigenschaften des Nucleoproteins [PDF]

open access: yes, 2014
Das in der I. Mitteilung beschriebene Nucleoprotein führt bei Zugabe zu Tropokollagen-Lösungen zur Bildung von kollagenen Fibrillen. Die Fibrillen-bildende Potenz des Nucleoproteins ist sehr groß.

Distinctive Nuclear Features of Dinoflagellates with A Particular Focus on Histone and Histone-Replacement Proteins

open access: yesMicroorganisms, 2018
Dinoflagellates are important eukaryotic microorganisms that play critical roles as producers and grazers, and cause harmful algal blooms. The unusual nuclei of dinoflagellates “dinokaryon„ have led researchers to investigate their enigmatic ...

m6 RNA methylation: an emerging common target in the immune response to cancer and severe acute respiratory syndrome-coronavirus-2 infection

open access: yesExploration of Medicine, 2023
m6A RNA methylation, a predominant type of RNA modification, is involved in regulating mRNA splicing, stability, and translation as well as the interaction between nucleoproteins and noncoding RNAs.

Viral proteins as a potential driver of histone depletion in dinoflagellates

open access: yesNature Communications, 2018
Dinoflagellates are known to use dinoflagellate-viral-nucleoproteins (DVNPs) in place of histones, yet this evolutionary transition is not well understood. Here, Irwin et al. use yeast expressing DVNP to show that DVNP displaces histones and that histone

Structural landscape of the respiratory syncytial virus nucleocapsids

open access: yesNature Communications, 2023
Human Respiratory Syncytial Virus (HRSV) is a prevalent cause of severe respiratory infections in children and the elderly. The helical HRSV nucleocapsid is a template for the viral RNA synthesis and a scaffold for the virion assembly. This cryo-electron

Intracellular Crosslinking of Filoviral Nucleoproteins with Xintrabodies Restricts Viral Packaging

open access: yesFrontiers in Immunology, 2017
Viruses assemble large macromolecular repeat structures that become part of the infectious particles or virions. Ribonucleocapsids (RNCs) of negative strand RNA viruses are a prime example where repetition of nucleoprotein (NP) along the genome creates a

Quantitative studies of nucleic acid in the cell by micro-spectrophotometry I. The critique and improvement of the microspectrophotometry [PDF]

open access: yes, 1959
Some critical experiments have been carried out on the microspectrophotometry using the lymphocytes of a mouse, stained with Feulgen reaction, revealing that most reliable value can be attained by illuminating the material with a small spot-light and ...
