Researchers Grow Human Gastrointestinal Cells Using Epithelial Stem Cells

by beredim in Stem Cells Freak

Kelli L. VanDussen, PhD, and Matthew A. CiorbaA method of growing human cells from tissue removed from a patient's gastrointestinal (GI) tract may one day help scientists develop tailor-made therapies for inflammatory bowel disease and other GI-related conditions.Reporting online recently in the journal Gut, researchers from the Washington University School of Medicine in St. Louis said they have made cell lines from individual patients in as little as two weeks.They have created more than 6........

August 7, 2014

by Erin Campbell in HighMag Blog

No matter how many brilliant discoveries are made by countless brilliant scientists, there will always be a lot of unknowns out there. These unknowns are what keep our mental wheels turning, our imaginations running, and our labs busy. Today’s image is from a paper that describes a newly-discovered process of vascular development called “canalogenesis.” Schlemm’s canal (SC) is a flattened tube that encircles the anterior portion of the eye and drains fluid from the area. Abnormal drainag........ Read more »

Thinking Makes My Head Hot

by Mark E. Lasbury in The 'Scope

The new movie, Lucy, contends that we only use 10% of our brain. Interesting, and true if you interpret the statement in one particular way. The interesting thought experiment is a contemplation of what would happen to us if we did only use 10% of our brain and then learned to use 100%. We would probably starve and die of fever. Research studies show that increased mental activity can lead to increased brain temperature, so should we should be picking kids for the gifted/talented program by temp........ Read more »

Vitamin D and schizophrenia meta-analysed

by Paul Whiteley in Questioning Answers

It's been a few weeks since I last talked about vitamin D on this blog and some finding or other talking about a deficiency of the stuff. Indeed, the last occasion was the publication of the Eva Kočovská study (see here) talking about issues with vitamin D being present across quite a few people on the autism spectrum, continuing a research trend (see here).So as to remedy this vitamin D blogging deficiency, today I'm talking about the systematic review and meta-analysis by Ghazaleh ........

EBOV-GP and antivirals: problems and possibilities

by thelonevirologist in Virology Tidbits

The characterisation of the viral entry mechanism of any virus allows to identify targets for antiviral drugs which can be used immediately following the (suspected or proven) exposure to the virus as well as preventing further spread of the infection within an infected person. This is especially important if treating viral diseases to which no vaccine is available or in situations where the goal is to contain a local epidemic or in the case of emerging viruses who only cause sporadic outbreaks ........

Molecular Competition Drives Adult Stem Cells to Specialize

by beredim in Stem Cells Freak

All adult organisms ranging from fruit flies to humans harbor adult stem cells, some of which renew themselves through cell division while others differentiate into the specialized cells needed to replace worn-out or damaged organs and tissues.Understanding the molecular mechanisms that control the balance between self-renewal and differentiation in adult stem cells is an important foundation for developing therapies to regenerate diseased, injured or aged tissue.Now, in the latest issue of the ........

Brain Striatum and Loss-Chasing in Gambling

by William Yates, M.D. in Brain Posts

Pathological gambling (PG) is a pattern of gambling characterized by loss of control and large gambling debts.The near-miss phenomenon in gambling is the gaming scenario where gamblers sense they were very close to winning.This near-miss phenomenon can be programmed into slot machines. For example, a gambler might be presented frequently with four cherries when five cherries would result in a huge payout.The response to the near-miss in PG is often a sense that a big win is just around the corne........

Video Tip of the Week: Biodalliance browser with HiSeq X-Ten data

by Mary in OpenHelix

Drama surrounding the $1000 genome erupts every so often, and earlier this year when the HiSeq X Ten setup was unveiled there was a lot of chatter–and questions: Is the $1,000 genome for real? And some push-back on the cost analysis: That “$1000 genome” is going to cost you $72M. A piece that offers nice […]... Read more »

Fall Leaves And Orange Flamingos

by Mark Lasbury in As Many Exceptions As Rules

Flamingos are pink because of their diet, but greater and lesser flamingos eat different things – and neither food is pink. The spirulina food of the lesser flamingo is a cyanobacterium called Arthospira fusiformis. Unforunately, there have been large die offs in lesser flamingos. Recent research has shown that this may be due to toxic alga blooms and production of toxins even by A. fusiformis. In addition, a newer study has shown that a bacteriophage is responsible for large die offs of A........ Read more »

Welcome to the weird world of weight illusions

by BPS Research Digest in BPS Research Digest

Normally bigger objects weigh more; breaking this rule provokes illusory perceptionsVisual illusions are useful to psychologists because, by tricking the brain, they provide clues about how it works. The same is true for weight illusions, it's just that they're far less well known. Now Gavin Buckingham at Heriot-Watt University has published a handy review of weight illusions, and he explores some of the thinking about their likely causes.Among the most studied is known as the "size-weight illus........
