Carrier-mediated processes in blood–brain barrier penetration and neural uptake of paraquat
- K. Shimizu, K. Ohtaki, K. Matsubara, K. Aoyama, H. Shiono
- Chemistry, Medicine
- Brain Research
- 6 July 2001
Due to the structural similarity to N-methyl-4-phenyl pyridinium (MPP(+)), paraquat might induce dopaminergic toxicity in the brain. However, its blood--brain barrier (BBB) penetration has not been… Expand
Targeting mitochondrial ATP-sensitive potassium channels—a novel approach to neuroprotection
- D. Busija, Z. Lacza, N. Rajapakse, K. Shimizu, T. Horiguchi
- Medicine
- Brain Research Reviews
- 1 November 2004
Mitochondrial responses to ischemic stress play an important role in necrosis and apoptosis of brain cells. Recent studies using several different experimental preparations have shown that activation… Expand
MitoKATP opener, diazoxide, reduces neuronal damage after middle cerebral artery occlusion in the rat
- K. Shimizu, Zsombor Lacza, N. Rajapakse, T. Horiguchi, J. Snipes, D. Busija
- Medicine
- 1 September 2002
We investigated effects of diazoxide, a selective opener of mitochondrial ATP-sensitive K+ (mitoKATP) channels, against brain damage after middle cerebral artery occlusion (MCAO) in male Wistar rat...
Enhancement of salt tolerance in soybean with NaCl pretreatment
- T. Umezawa, K. Shimizu, Morio Kato, T. Ueda
- Biology
- 1 September 2000
Acclimation response to salt stress in soybean (Glycine max [L.] Merr. cv. Lee) was found in this study. Soybean seedlings were exposed to 0, 34 and 68 mM NaCl for 23 days (pretreatment), thereafter… Expand
Activation of mitochondrial ATP-sensitive potassium channels prevents neuronal cell death after ischemia in neonatal rats
- Nishadi Rajapakse, K. Shimizu, B. Kis, J. Snipes, D. Busija
- Medicine
- Neuroscience Letters
- 26 July 2002
Activation of mitochondrial ATP-sensitive potassium channels (mK(ATP)) has been shown to protect against cell death following ischemia/reperfusion in the heart but not in brain. We examined whether… Expand
N-methyl-D-aspartate-induced vasodilation is mediated by endothelium-independent nitric oxide release in piglets.
- F. Domoki, J. V. Perciaccante, K. Shimizu, M. Puskar, D. Busija, F. Bari
- Chemistry, Medicine
- American journal of physiology. Heart and…
- 1 April 2002
N-methyl-D-aspartate (NMDA) elicits pial arteriolar dilation that has been associated with neuronal nitric oxide (NO) production. However, endothelial factors or glial P-450 epoxygenase products may… Expand
Opening of Mitochondrial ATP-Sensitive Potassium Channels Is a Trigger of 3-Nitropropionic Acid–Induced Tolerance to Transient Focal Cerebral Ischemia in Rats
- T. Horiguchi, B. Kis, N. Rajapakse, K. Shimizu, D. Busija
- Medicine
- Stroke
- 1 April 2003
Background and Purpose— The role of mitochondrial ATP-sensitive potassium channels (mitoKATP) in ischemic tolerance has been well documented in heart, but little work has been done in brain. To… Expand
Mechanisms involved in the cerebrovascular dilator effects of cortical spreading depression
- D. Busija, F. Bari, F. Domoki, T. Horiguchi, K. Shimizu
- Medicine
- Progress in Neurobiology
- 11 December 2008
Cortical spreading depression (CSD) leads to dramatic changes in cerebral hemodynamics. However, mechanisms involved in promoting and counteracting cerebral vasodilator responses are unclear. Here we… Expand

Effects of Non-stomatal Components on Photosynthesis in Soybean under Salt Stress
- T. Umezawa, K. Shimizu, Morio Kato, T. Ueda
- Chemistry
- 1 March 2001
To elucidate the physiological mechanism of inhibition of photosynthesis by salt stress in soybean (Glycine max (L.) Merr.), the photosynthetic activity, Na+ accumulation and ABA content of two… Expand
