The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Relationship of Lead Exposure with Workers\' Blood Pressure and Blood Components: A Case Study

open access: yesArchives of Occupational Health, 2020
Background: Lead is one of the most widely used metals in the industries and is the amplest metal element on the Earth’s crust. This metal disrupts the physiological processes of the body due to its accumulation in various tissues.

Indications for transfusion of donor blood components in emergency surgery

open access: yesТрансплантология (Москва), 2018
In terms of complications due to allogeneic blood transfusions, it is necessary to use the latter only in accordance with the strict indications elaborated specifically for each component.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Quality control in the different stages of producing red blood cell concentrate from dogs

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia
The objective of this study was to perform a quality control assessment of red blood cells after standardization of the blood production stages. For this purpose, separation of the blood components to obtain red blood cells, the storage of the blood ...

BLOOD TRANSFUSION IN LUNG OPERATIONS

open access: yesВестник хирургии имени И.И. Грекова, 2016
The authors admit the risks of blood transfusion, as well as the fact that the blood is a limited resource. These conclusions became the basis of the research in order to make an analysis and develop transfusion strategies in the hospital.

Depolarization increases cellular light transmission [PDF]

open access: yes, 2008
Application of optical methods to human brain tissue in vivo, e.g., measuring oxyhemoglobin and deoxyhemoglobin concentration changes with near-infrared spectroscopy (NIRS), requires the a priori assumption that background optical properties remain ...

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
