Particle species dependence of cell survival RBE: Evident and not negligible

Dependence on neutron energy of the OER and RBE.

Systematic analysis of RBE and related quantities using a database of cell survival experiments with ion beam irradiation

For tumor therapy with light ions and for experimental aspects in particle radiobiology the relative biological effectiveness (RBE) is an important quantity to describe the increased effectiveness of particle radiation. By establishing and analysing a database of ion and photon cell survival data, some remarkable properties of RBE-related quantities were observed. The database consists of 855 i...

پیش گیری از آسیب های ورزشی مهمترین موضوع در برخورد با آسیب های ورزشی است. برای پیش گیری از آسیب های ورزشی شناسایی عوامل و ریسک فاکتورهای مستعد کننده آسیب از اهمیت ویژه ای برخوردار است. هدف از انجام این تحقیق شناسایی ریسک فاکتورهای آسیب در بین کشتی گیران نخبه استان کرمانشاه می باشد. بدین منظور60 نفر کشتی گیر در سه گروه شامل: آسیب دیده منیسک، رباط صلیبی قدامی و افراد غیر آسیب دیده در گروههای20 نف...

EvIdEnt And non-EvIdEnt FunctIons

Targeting nuclear DNA-encoded tRNA is a quasi-ubiquitous process, found in a variety of species, although the mechanisms of this pathway seem to differ from one system to another. In all cases reported, this import concerns small non-coding RNAs and the vast majority of imported RNAs are transfer RNAs. If was commonly assumed that the main criterion to presume a tRNA to be imported is the absen...

Negligible particle-specific antibacterial activity of silver nanoparticles.

For nearly a decade, researchers have debated the mechanisms by which AgNPs exert toxicity to bacteria and other organisms. The most elusive question has been whether the AgNPs exert direct "particle-specific" effects beyond the known antimicrobial activity of released silver ions (Ag(+)). Here, we infer that Ag(+) is the definitive molecular toxicant. We rule out direct particle-specific biolo...
