Background: Enumeration of residual DNA repair foci 24 hours or more after exposure to ionizing radiation (IR) is often used to assess the efficiency of DNA double-strand break repair. However, the relationship between the number of residual foci in irradiated cells and the radiation dose is still poorly understood. The aim of this work was to investigate the dose responses for residual DNA repair foci in normal human fibroblasts after X-ray exposure in the absorbed dose range from 0.

RT has generally been reported to be sharply limited by ionizing radiation (IR)-induced toxicity, thereby constraining the control effect of RT on tumor growth. FLASH-RT is the delivery of ultra-high dose rate (UHDR) several orders of magnitude higher than what is presently used in conventional RT (CONV-RT).

- - The traditional methods for making colloidal crystals struggle to achieve the necessary conditions of uniform thickness, 3D ordering, and large defect-free areas, which are essential for creating photonic structures with tunable properties.
- - A new approach using the Langmuir-Blodgett process and spin-coating has been developed, enabling the formation of high-quality 3D colloidal crystals with minimal defects.
- - This innovative technique resulted in polystyrene colloidal crystals that covered about 96.5% of the substrate and showed strong 3D ordering, as evidenced by specific optical properties related to Bragg diffraction.
Structures of hexamethyl-[1,1'-biphenyl]-4,4'-diammonium salts.
Acta Crystallogr B Struct Sci Cryst Eng Mater
December 2024
The crystal structures of nine hexamethyl-[1,1'-biphenyl]-4,4'-diammonium (HMB) salts are described: the iodide (2), triiodide (3), succinate (4), fumarate (5), tetravanadate (6), hydroterephthalate (7) and perylenetetracarboxylate (8), as well as pentamethyl-[1,1'-biphenyl]-4,4'-diammonium iodide (1) and the metal-organic framework sodium diacetylenedisalicylate-HMB (9). HMB carbonate (10) has been synthesized as an important intermediate for a promising anti-metal-organic framework (`anti-MOF'). All the described compounds are characterized by high solubility in water.

The IMA level and blood serum antioxidant capacity increased in the following order: healthy non-pregnant women→healthy pregnant women→patients with moderate preeclampsia→patients with severe preeclampsia (p<0.001).
