brain Brainstorming for new science portal By marstonscience.blogspot.com Published On :: Tue, 25 Mar 2008 15:08:00 +0000 We need to start brainstorming for ideas and features that we want on the new science portal so we'll be prepared for when we locate a web designer.Here are a list of some other science library websites. Not all are great but I'd like for us to discuss what elements we like and which features we don't like (just as important). Please feel free to post links to other libraries you think are worthy of critique. Also, if there are general guidelines and features that you'd like to include please post about those too.My first impression looking at these sites is how busy they all are. Lots of links and it seems overwhelming at first glance. Its a decision that we'll have to make about how much information should be quickly accessible on the main page but yet still easily usable. Caltech's library page is the most easily navigated, IMO. I like the quick drop down boxes and the selection of links. I especially like the menu for authors - as the issue of open access and author rights becomes more important on campus, we'll need to take an active role in helping the faculty understand their rights and options for publishing.Berkeley: Chemistry: http://www.lib.berkeley.edu/CHEM/ Engineering: http://www.lib.berkeley.edu/ENGI/ Physics/Ay: http://www.lib.berkeley.edu/PHYS/Caltech: http://library.caltech.edu/Chicago : http://www1.lib.uchicago.edu/e/crerar/index.php3Irvine: http://www.lib.uci.edu/libraries/science.htmlMichigan: http://www.lib.umich.edu/science/MIT Science Library: http://libraries.mit.edu/science/Oregon Science Library: http://libweb.uoregon.edu/scilib/Santa Cruz: http://libweb.uoregon.edu/scilib/ Full Article portal

brain Glucocerebrosidases catalyze a transgalactosylation reaction that yields a newly-identified brain sterol metabolite, galactosylated cholesterol [Glycobiology and Extracellular Matrices] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 β-Glucocerebrosidase (GBA) hydrolyzes glucosylceramide (GlcCer) to generate ceramide. Previously, we demonstrated that lysosomal GBA1 and nonlysosomal GBA2 possess not only GlcCer hydrolase activity, but also transglucosylation activity to transfer the glucose residue from GlcCer to cholesterol to form β-cholesterylglucoside (β-GlcChol) in vitro. β-GlcChol is a member of sterylglycosides present in diverse species. How GBA1 and GBA2 mediate β-GlcChol metabolism in the brain is unknown. Here, we purified and characterized sterylglycosides from rodent and fish brains. Although glucose is thought to be the sole carbohydrate component of sterylglycosides in vertebrates, structural analysis of rat brain sterylglycosides revealed the presence of galactosylated cholesterol (β-GalChol), in addition to β-GlcChol. Analyses of brain tissues from GBA2-deficient mice and GBA1- and/or GBA2-deficient Japanese rice fish (Oryzias latipes) revealed that GBA1 and GBA2 are responsible for β-GlcChol degradation and formation, respectively, and that both GBA1 and GBA2 are responsible for β-GalChol formation. Liquid chromatography–tandem MS revealed that β-GlcChol and β-GalChol are present throughout development from embryo to adult in the mouse brain. We found that β-GalChol expression depends on galactosylceramide (GalCer), and developmental onset of β-GalChol biosynthesis appeared to be during myelination. We also found that β-GlcChol and β-GalChol are secreted from neurons and glial cells in association with exosomes. In vitro enzyme assays confirmed that GBA1 and GBA2 have transgalactosylation activity to transfer the galactose residue from GalCer to cholesterol to form β-GalChol. This is the first report of the existence of β-GalChol in vertebrates and how β-GlcChol and β-GalChol are formed in the brain. Full Article
brain Genetically engineered 'Magneto' protein remotely controls brain and behaviour By www.theguardian.com Published On :: 2016-03-24T14:30:03Z “Badass” new method uses a magnetised protein to activate brain cells rapidly, reversibly, and non-invasivelyResearchers in the United States have developed a new method for controlling the brain circuits associated with complex animal behaviours, using genetic engineering to create a magnetised protein that activates specific groups of nerve cells from a distance.Understanding how the brain generates behaviour is one of the ultimate goals of neuroscience – and one of its most difficult questions.

brain Live imaging of synapse density in the human brain By www.theguardian.com Published On :: 2016-08-10T12:00:55Z A new imaging technique may give researchers fresh insights into brain development, function, and diseaseThe human brain is often said to be the most complex object in the known universe, and there’s good reason to believe that it is. That lump of jelly inside your head contains at least 80 billion nerve cells, or neurons, and even more of the non-neuronal cells called glia. Between them, they form hundreds of trillions of precise synaptic connections; but they all have moveable parts, and these connections can change. Neurons can extend and retract their delicate fibres; some types of glial cells can crawl through the brain; and neurons and glia routinely work together to create new connections and eliminate old ones.These processes begin before we are born, and occur until we die, making the brain a highly dynamic organ that undergoes continuous change throughout life. At any given moment, many millions of them are being modified in one way or another, to reshape the brain’s circuitry in response to our daily experiences. Researchers at Yale University have now developed an imaging technique that enables them to visualise the density of synapses in the living human brain, and offers a promising new way of studying how the organ develops and functions, and also how it deteriorates in various neurological and psychiatric conditions.

The findings, published in the Journal of Neuroscience, suggest that breathing does not merely supply oxygen to the brain and body, but may also organise the activity of populations of cells within multiple brain regions to help orchestrate complex behaviours.

From the moment we are are born, we prefer to look at faces than at other, inanimate objects, and, being social animals, we encounter faces every day of our lives. The face is the first thing we look to when identifying other people; faces also convey emotions, informing us of peoples’ mood, and from them we can usually determine a person’s sex and, sometimes, roughly how old they are. Eye movements can also reveal to us something about another person’s intentions.

brain Sleep may help us to forget by rebalancing brain synapses By www.theguardian.com Published On :: 2017-02-03T11:00:13Z New research provides evidence for the idea that sleep restores cellular homeostasis in the brain and helps us to forget irrelevant informationWe spend one third of our lives sleeping, but we still do not know exactly why we sleep. Recent research shows that that the brain does its housekeeping while we sleep, and clears away its waste. According to another hypothesis, sleep plays the vital role of restoring the right balance of brain synapses to enhance learning, and two studies published in today’s issue of Science now provide the most direct evidence yet for this idea.We do know that sleep is important for consolidating newly formed memories. During waking hours, we learn all kinds of new information, both consciously and unconsciously. To store it, the brain modifies large numbers of synaptic connections, making some of them stronger and larger, and it’s now thought that as we sleep other synapses are weakened or destroyed, so that the important new information is stored for later use, while irrelevant material, which could interfere with learning, is not.

brain How to become a super memorizer – and what it does to your brain By www.theguardian.com Published On :: 2017-03-08T17:30:24Z New research shows that we can train our brains to become memory champions To many of us, having to memorize a long list of items feels like a chore. But for others, it is more like a sport. Every year, hundreds of these ‘memory athletes’ compete with one another in the World Memory Championships, memorising hundreds of words, numbers, or other pieces of information within minutes. The current world champion is Alex Mullen, who beat his competitors by memorizing a string of more than 550 digits in under 5 minutes. You may think that such prodigious mental feats are linked to having an unusual brain, or to being extraordinarily clever. But they are not. New research published in the journal Neuron shows that you, too, can be a super memorizer with just six weeks of intensive mnemonic training, and also reveals the long-lasting changes to brain structure and function that occur as a result of such training.

brain Researchers develop non-invasive deep brain stimulation method By www.theguardian.com Published On :: 2017-06-01T16:00:11Z Researchers at MIT have developed a new method of electrically stimulating deep brain tissues without opening the skullSince 1997, more than 100,000 Parkinson’s Disease patients have been treated with deep brain stimulation (DBS), a surgical technique that involves the implantation of ultra-thin wire electrodes. The implanted device, sometimes referred to as a ‘brain pacemaker’, delivers electrical pulses to a structure called the subthalamic nucleus, located near the centre of the brain, and effectively alleviates many of the physical symptoms of the disease, such as tremor, muscle rigidity, and slowed movements. DBS is generally safe but, like any surgical procedure, comes with some risks. First and foremost, it is highly invasive, requiring small holes to be drilled in the patient’s skull, through which the electrodes are inserted. Potential complications of this include infection, stroke, and bleeding on the brain. The electrodes, which are implanted for long periods of time, sometimes move out of place; they can also cause swelling at the implantation site; and the wire connecting them to the battery, typically placed under the skin of the chest, can erode, all of which require additional surgical procedures.

The core of this group were Columbia University professors, who knew and trusted each other, and were willing to take risks and work long unpaid hours to promote a candidate that they believed could turn around a nation in crisis. End Date: March 26th, 2010Nov 6 2009 to Mar 26 2010Teaser Image: Friday, November 6, 2009 to Friday, March 26, 2010Start Date: Friday, November 6, 2009Teaser Image Caption: Irving Browning Buy My Apples, 1929 Gelatin Silver Print New-York Historical Society, Gift of Irving Browning.Although at first a casual circle, the group became tightly organized after FDR's nomination. After the election, they were publicly christened the "Brain Trust," and became the central component of the New Deal. This exhibition will focus on the three key members of the Brain Trust—Raymond Moley, Rexford Tugwell, and Adolph Berle—and two of the New Deal cabinet members with whom they worked to bring about FDR's radical changes—Frances Perkins and Harry Hopkins.

brain A new brain mitochondrial sodium-sensitive potassium channel: effect of sodium ions on respiratory chain activity [RESEARCH ARTICLE] By jcs.biologists.org Published On :: 2020-04-23T01:49:49-07:00 Javad Fahanik-babaei, Bahareh Rezaee, Maryam Nazari, Nihad Torabi, Reza Saghiri, Remy Sauve, and Afsaneh EliassiWe have determined the electropharmacological properties of a new potassium channel from brain mitochondrial membrane by planar lipid bilayer method. Our results showed the presence of a channel with a conductance of 150 pS at potentials between 0 and –60 mV in 200 cis/50 trans mM KCl solutions.The channel was voltage-independent, with an open probability value ~0.6 at different voltages. ATP did not affect current amplitude and Po at positive and negative voltages. Notably, adding iberiotoxin, charybdotoxin, lidocaine, and margatoxin had no effect on the channel behavior. Similarly, no changes were observed by decreasing the cis-pH to 6. Interestingly, the channel was inhibited by adding sodium in a dose dependent manner. Our results also indicated a significant increase in mitochondrial complex IV activity and membrane potential and decrease in complex I activity and mitochondrial ROS production in the presence of sodium ions.We propose that inhibition of mitochondrial K+ transport by Na ions on K+ channel opening may be important for cell protection and ATP synthesis.
