For first time, brain cells generated in a dish
Regenerative medicine scientists at the University of Florida's McKnight Brain Institute have created a system in rodent models that for the first time duplicates neurogenesis -- the process of generating new brain cells -- in a dish. Writing in today's (June 13) Proceedings of the National Academy of Sciences, researchers describe a cell culture method that holds the promise of producing...Neurons generated in the adult brain learn to respond to novel stimuli
New brain cells that develop in the olfactory system of adult mice appear to play a role in the brain different from that of older neurons. The new olfactory neurons are especially sensitive to novel stimuli, preferentially learning to respond to new odors. This level of flexibility suggests that such newly-generated neurons could be induced to adapt to and integrate into other regions of the b...Fractionating DNA Fragments Generated by Differential Display PCR
Pfizer Central Research, Sandwich, UK. 01304 618482 Differential display PCR (DDPCR) is a widely used technique foridentifying genes differentially expressed between cell types. Application ofDDPCR to allergic disease provides a potential means for elucidating themechanisms involved in allergic...Advancing the quality control methodology to assess isolated total RNA and generated fragmented cRNA
This Application Note describes how Gene Logic, Inc., has improved itsability to analyze the quality of total RNA and fragmented cRNA by usingthe Agilent 2100 bioanalyzer. The Eukaryote Total RNA Nano and Picoassays are currently being utilized to examine the 28S/18S ratio...Inducing RNAi with siRNA Cocktails Generated by RNase III
Ambion, Inc. Austin, TX 78744-1832 Small interfering RNA (siRNA) is an extremely...Sensations Generated By Cocaine And Methamphetamine Abuse Are Not Same.
Investigators from UCLA had found that the there is a marked difference between the sensations generated by cocaine and methamphetamine use in onset, pattern and duration of their “highs”. // The study shows that subjective, or self-reported, responses to cocaine peak and decline more rapidly than those of methamphetamine. Cardiovascular responses to the two stimulants are similar at...Visual Awareness Is Generated At the Back Of The Brain
Researchers at Barrow Neurological Institute in Phoenix have discovered that the key to visual awareness is located in the occipital lobe or the rear portion of the brain.// It has always puzzled scientists as to how the human mind can quickly gauge the object that it is seeing. Now researchers say that this power to quickly analyze this is generated in a small portion at the back of...Surgicel Fibrillar Absorbable Hemostat (oxidized regenerated cellulose)
