Building modular motor complexes
Satellite RNA guides kinetochore assembly R ošić et al. reveal that a non-coding RNA transcribed from repetitive DNA sequences promotes kinetochore assembly and chromosome segregation during mitosis. Centromeres—the chromosome regions where kinetochore proteins assemble and attach chromosomes to the mitotic spindle—are defi ned by epige-netic factors such as the histone variant CENP-A rather th...
متن کاملAtherosclerosis Defeat of the Defense ? Ton
Heme oxygenases (HOs) are rate-limiting enzymes that catalyze the conversion of heme into equimolar amounts of biliverdin, carbon monoxide (CO), and iron.1 Biliverdin is subsequently reduced to bilirubin pigment by biliverdin reductase.2 The heme oxygenases consist of 2 major isoforms, HO-1 and HO-2. Whereas HO-2 is constitutively produced within the brain, testes, and the endothelium, HO-1 gen...
متن کاملTraumatic Optic Neuropathy [TON] - A Review
It is generally presumed that penetrating injuries of the orbit are associated with direct optic nerve injury. The incidence of TON after craniofacial trauma has been reported to be 0.5-1.5 % in older series. However, recent surveys report a higher figure; 2-5 % . This increased incidence may represent the diagnosis of subtle forms of TON closer to the time of injury. These types of cases appea...
متن کاملIonic Liquid assisted Synthesis of Zeolite-TON
An ionic liquid assisted strategy for the synthesis of zeolitic material is reported. This strategy is a solid state synthetic method and the ionic liquid is employed as structure directing agent. A TON-type zeolite, which contains one-dimensional 10-member-ring, is successfully synthesized with the assistance of the ionic liquid, 1-ethyl-3-methylimidazolium bromide. This finding improves our u...
متن کاملSalt is getting under our skin ∗ Ton
Traditionally, the Na+ cation is thought to be largely restricted to the extracellular compartment, while K+ is stored intracellularly. This balance is maintained by the activity of the Na/K-ATPase sodium pump in the cell membrane. As Na+ and its accompanying anions are the principal extracellular osmoles, extracellular accumulation of Na+ inevitably also leads to fluid retention and expansion ...
