Harvard scientists discover method to revert mature liver cells back to a stem cell-like state

by beredim in Stem Cells Freak

Fernando CamargoCredit Harvard Stem Cell Institute researchers at Boston Children's Hospital have new evidence in mice that it may be possible to repair a chronically diseased liver by forcing mature liver cells to revert back to a stem cell-like state. The researchers, led by Fernando Camargo, PhD, arumbled upon this discovery while investigating whether a biochemical cascade called Hippo, which controls how big the liver grows, also affects cell fate.The unexpected answer, appearing in th........

Smoking in recovery – the Blue Whale in the room 

by DJMac in Recovery Review

Blue Whale Alert Smoking and other addictions go hand in hand. In treatment populations, it’s usual to find that about 80-90% of clients are current smokers, compared to 20% of say the Scottish population. Nobody has done a survey on smoking prevalence in recovering populations in Scotland, but I would guess that for smoking in recovery [...]

Smoking Linked to Brain White Matter Dysfunction

by William Yates, M.D. in Brain Posts

Tobacco smoking and nicotine dependence produce harmful effects on the brain.Some of these effects are related to direct effects on vascular health. Vascular changes seen with smoking are known to contribute to increased risk for stroke and dementia.Advances in brain imaging techniques allow for more direct study on smoking's effect on specific brain structures.Diffusion tensor imaging (DTI) is a relatively recent imaging tool allowing for study of brain white matter function.Brain white matter ........

Autoantibodies and autism again

by Paul Whiteley in Questioning Answers

Autoantibodies - that is, antibodies directed at the body itself - are no stranger to autism research. I've talked about various types of autoantibody being detected in elevated levels in certain groups and cases of autism (see here for example). The paper by Gehan Mostafa and colleagues [1] adds to the roll call with their findings: "The seropositivity of anti ds-DNA and/or ANA [antinuclear antibodies] in autistic children was 42%".Charge ! @ Wikipedia Before progressin........

Discussions in chronic pain management

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

Amongst the arguments around interdisciplinary programmes are discussions about how long or intense a programme should be (the “dose”), the content and what is or isn’t necessary within them, and personnel or who should or shouldn’t be involved. I thought I’d take a little look at some of these arguments.... Read more »

Anabolic steroids – ignorance is not bliss

by DJMac in Recovery Review

Anabolic steroids are used to enhance body image. I took a look at this recently. Their use is fairly common in gyms. A study of almost 800 gay men attending gyms in London found that one in seven had used steroids in the last year and almost 12% had injected. All reported side effects including [...]

Homocysteine, gut permeability and MMP-9?

by Paul Whiteley in Questioning Answers

A speculative post this one, on the paper by Hao Ding and colleagues [1] (open-access here) looking at how, in a rodent model of colitis, homocysteine (the big 'H') might play some part in aggravating "inflammatory damage" potentially through promotion of some of the matrix metalloproteinases, MMP-2 and MMP-9. The words: "Hcy [homocysteine] can increase intestinal permeability" added to the interest.If you're used to reading about autism research on this blog, you might be wondering why on ........

Can a gluten-free diet positively affect cognitive performance?

by Paul Whiteley in Questioning Answers

No, I am not suggesting that a gluten-free diet is the new nootropic (cognitive enhancer) of choice with the title of this post despite previous media headlines on the subject."Got gluten?"☺  @ Wikipedia I am however very, very interested in the results reported by Irene Lichtwark and colleagues [1] (open-access here) which suggested that in "newly diagnosed coeliac disease, cognitive performance improves with adherence to the gluten-free diet in parallel to mucosal healing........

Stem cells hold keys to body's plan

by beredim in Stem Cells Freak

Case Western Reserve researchers have discovered landmarks within pluripotent stem cells that guide how they develop to serve different purposes within the body. This breakthrough offers promise that scientists eventually will be able to direct stem cells in ways that prevent disease or repair damage from injury or illness. The study and its results appear in the June 5 edition of the journal Cell Stem Cell.Pluripotent stem cells are so named because they can evolve into any of the cell types th........ Read more »

Fasting triggers hematopoietic stem cells to repair damages of the immune system

by beredim in Stem Cells Freak

Valter LongoCredit: Dietmar QuistorfIn the first evidence of a natural intervention triggering stem cell-based regeneration of an organ or system, a study in the June 5 issue of the Cell Press journal Cell Stem Cell shows that cycles of prolonged fasting not only protect against immune system damage -- a major side effect of chemotherapy -- but also induce immune system regeneration, shifting stem cells from a dormant state to a state of self-renewal.Results from both mice and a Phase 1 human cl........

New method reveals key protein for embryonic stem cell differentiation

by beredim in Stem Cells Freak

Directed Network Wiring, a new method to simplify the study of protein networks, is illustrated.Proteins are responsible for the vast majority of the cellular functions that shape life, but like guests at a crowded dinner party, they interact transiently and in complex networks, making it difficult to determine which specific interactions are most important.Now, researchers from the University of Chicago say they have pioneered a new technique that simplifies the study of protein networks and id........

Human induced pluripotent stem cells successfully transplanted and grown in pigs

by beredim in Stem Cells Freak

Michael RobertsOne of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts.This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection.“The rejectio........ Read more »

Corticosteroid therapy in regressive autism

by Paul Whiteley in Questioning Answers

I note that the recent paper by Frank Duffy and colleagues [1] (open-access here) seems to be receiving quite a bit of interest, and their suggestion that corticosteroid therapy might be something to look at more scientifically when it comes to some cases of regressive autism. The fact that the Duffy paper also got it's own commentary [2] made me think that this is something I should be discussing on this blog.So, a few details about the Duffy paper bearing in mind it is open-access:Well, f........

Walking a Mile in Your Shoes: Treating Eating Disorders with a Personal History of Eating Problems

by Andrea in Science of Eating Disorders

A big topic at ICED, and one that seems to continually resurface, is treatment professionals in recovery. One the one hand, many see healthcare professionals with a history of eating disorders as possessing a kind of empathy that may be inaccessible to those who have not “been there.” On the other, some argue that this history complicates the patient-professional relationship in potentially detrimental ways.
You’ll find proponents of both sides of this debate from both professional a........ Read more »

Types of Mathematics Learning Disorders

by William Yates, M.D. in Brain Posts

Learning mathematics is a complex process that forms a key element in modern education.Significant mathematics learning difficulties emerge in 5 to 10 per cent of all elementary and secondary education students.Struggling to acquire skills in mathematics is more than a single deficit and appears to involve multiple cognitive skills.Giannis Karagiannakis and colleagures recently summarized what is known about mathematics learning disorders and proposed four subtypes. I will summarize these subtyp........ Read more »
