Radiation issues for piloted Mars mission.
Badhwar GD, Nachtwey DS, Yang TC-H. Badhwar GD, et al. Adv Space Res. 1992;12(2-3):195-200. doi: 10.1016/0273-1177(92)90108-a. Adv Space Res. 1992. PMID: 11537008 Review.
Current radiation risk is estimated using the idea of absorbed dose and ICRP-26, LET-dependent quality factors. In a spacecraft with aluminum walls (2 g cm-2) at solar minimum the calculated dose equivalent is 0.73 Sv for a 406-day mission. ...

Good and bad protons: genetic aspects of acidity stress responses in plants.
Shavrukov Y, Hirai Y. Shavrukov Y, et al. J Exp Bot. 2016 Jan;67(1):15-30. doi: 10.1093/jxb/erv437. Epub 2015 Sep 28. J Exp Bot. 2016. PMID: 26417020 Review.
Physiological aspects of acidity stress in plants (synonymous with H(+) rhizotoxicity or low-pH stress) have long been a focus of research, in particular with respect to acidic soils where aluminium and H(+) rhizotoxicities often co-occur. However, toxic H(+) and Al(3+) el …

Cations in the didanosine tablet reduce ciprofloxacin bioavailability.
Sahai J, Gallicano K, Oliveras L, Khaliq S, Hawley-Foss N, Garber G. Sahai J, et al. Clin Pharmacol Ther. 1993 Mar;53(3):292-7. doi: 10.1038/clpt.1993.24. Clin Pharmacol Ther. 1993. PMID: 8453847 Clinical Trial.
The effect of the magnesium-aluminum cations contained in didanosine chewable tablets on ciprofloxacin pharmacokinetics was evaluated in 12 healthy volunteers. ...

Exogenous gamma-aminobutyric acid alleviates oxidative damage caused by aluminium and proton stresses on barley seedlings.
Song H, Xu X, Wang H, Wang H, Tao Y. Song H, et al. J Sci Food Agric. 2010 Jul;90(9):1410-6. doi: 10.1002/jsfa.3951. J Sci Food Agric. 2010. PMID: 20549790
BACKGROUND: Proton (H(+)) and aluminium (Al(3+)) toxicities are major factors limiting crop production on acid soils, while gamma-aminobutyric acid (GABA) is a non-protein amino acid involved in various stress tolerances in plants. ...

Analyses of the secondary particle radiation and the DNA damage it causes to human keratinocytes.
Lebel EA, Rusek A, Sivertz MB, Yip K, Thompson KH, Tafrov ST. Lebel EA, et al. J Radiat Res. 2011;52(6):685-93. doi: 10.1269/jrr.11015. J Radiat Res. 2011. PMID: 22104266 Free article.
We simulated the generation of secondary radiation after the impact of protons and iron ions on an aluminum shield. We also measured the intensity and the type of the resulting secondary particles at two sample locations; our findings agreed well with our predictions. ...

Human exposure to large solar particle events in space.
Townsend LW, Wilson JW, Shinn JL, Curtis SB. Townsend LW, et al. Adv Space Res. 1992;12(2-3):339-48. doi: 10.1016/0273-1177(92)90126-i. Adv Space Res. 1992. PMID: 11537027
Using this computer code, estimates of human exposure in interplanetary space, behind nominal (2 g/cm2) and storm shelter (20 g/cm2) thicknesses of aluminum shielding, are made for the large solar proton event of August 1972. ...

Antacid interaction with new quinolones: dose regimen recommendations based on pharmacokinetic modeling of clinical data for ciprofloxacin, gatifloxacin and norfloxacin and metal cations.
Miyata K, Ohtani H, Tsujimoto M, Sawada Y. Miyata K, et al. Int J Clin Pharmacol Ther. 2007 Jan;45(1):63-70. doi: 10.5414/cpp45063. Int J Clin Pharmacol Ther. 2007. PMID: 17256452
The model was fitted to the reported time profiles ofciprofloxacin (CPFX) plasma concentration after concomitant administration with aluminum hydroxide/magnesium hydroxide antacid (Al/Mg antacid; Maalox, Maalox70) at various dosing intervals to obtain the pharmacokinetic p …

Effect of some polyvalent cations on plaque formation in vivo.
Skjörland K, Gjermo P, Rölla G. Skjörland K, et al. Scand J Dent Res. 1978 Mar;86(2):103-7. doi: 10.1111/j.1600-0722.1978.tb00614.x. Scand J Dent Res. 1978. PMID: 274799
It was found that SnF2 AND SnCl2 exhibited a marked plaque-inhibiting capacity compared with NaF or NaCl. The aluminum, zinc and magnesium salts also reduced plaque formation, although not to the same degree. ...
