It is now considered binding of excessive amyloid β peptide (Aβ) to amyloid β peptide binding alcohol dehydrogenase (ABAD) in the brain cells of Alzheimer’s disease patients hinders the normal...
View ArticleDiscovering a regulator factor influencing neuron generation in the brain
otch functions as a molecular switch for neural stem/progenitor cell fate during cortex development, and biochemical and cellular studies have showed that A Disintegrin and Metalloprotease 10 (ADAM10)...
View ArticleCarbenoxolone pretreatment and treatment of posttraumatic epilepsy
Carbenoxolone is a gap junction blocking agent and can pass the blood-brain barrier. The mode of action of carbenoxolone is to phosphorylate connexin through activating protein kinases and G proteins...

A study published in the Neural Regeneration Research (Vol. 8, No. 2, 2013) assessed the influence of medium-intensity (treadmill at a speed of 19.3 m/min until exhaustion) and high-intensity...
View ArticleCaMKII inhibitor KN-93 can be used for treating cognitive impairment
Calcium/calmodulin-dependent protein kinase II (CaMKII) has been reported to play a role in intelligent changes induced by vascular dementia and temporal lobe epilepsy and cognitive impairment caused...
View ArticleMild hypothermia can protect diffuse axonal injury
Numerous studies demonstrate that 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) can decrease brain temperature, and has a neuroprotective effect against traumatic brain injury.
View ArticleSelective cerebral deep hypothermia and BFO can enhance tolerance to ischemia...
Excitotoxicity induced by the release of a large amount of excitatory amino acids after cerebral ischemia is the major mechanism underlying ischemic brain injury and nerve cell death, which can be...
View ArticleBats may adjust their echolocating calls to compete with ambient noise
A study reveals how echolocating bats alter the amplitude and frequency of their calls to communicate over the din of a bustling environment. Birds, humans, and other mammals instinctively raise their...
View ArticleA potential link between smoking and cystic fibrosis
Certain lung-related clinical symptoms in cigarette smokers might be due to defects in the function of a protein implicated in cystic fibrosis, according to a study. Many smokers suffer from chronic...
View ArticleEvidence for a female protective effect against inherited autistic behaviors
A study suggests that autistic behavioral impairments may be less common in females than males because females require a greater number of familial risk factors to show the same degree of autistic...
View ArticleGrasslands declining in the Western Corn Belt
A study finds that grasslands in the north-central U.S. are rapidly converting into cropland. High corn and soy commodity prices, driven by the demand for biofuels, have created incentives for...
