GENETICALLY MODIFIED (GM) CROPS- FRIEND OR FOE?

by Amy Swanston in Antisense Science

With the Council for Science and Technology advising that we need to rethink our stance on GM food, we decided to look into some of the science behind genetic engineering to see what all the fuss is about.

Every year the world population increases, as does our need to find new sources of food. Globally malnutrition affects 34 million children across the world- but could GM crops be the cure? A huge proportion of land is simply not good enough to grow food or has problems with pests, but if we........ Read more »

When Sleeping Pills Don't Work

by William Yates, M.D. in Brain Posts

Hypnotics or sleeping pills typically are effective and indicated as an option for the short-term relief of transient insomnia.However, a minority of individuals report persistent insomnia and lack of sleep despite use of a hypnotic.When drugs that typically treat a disorder fail to work, it is important to reconsider the accuracy of the diagnosis.Yun Li and colleagues from China recently published a case report illustrating this issue in the Journal of Clinical Sleep Medicine.They reported on a........

A specific female ASD phenotype is emerging...

by Paul Whiteley in Questioning Answers

The title of this brief post is a quote taken from the abstract of the paper by Frazier and colleagues [1] who, following an analysis of participants included in the Simons Simplex Collection, concluded that autism research and practice might well consider looking at differences in the presentation of autism spectrum disorders (ASDs) between the sexes.The Lady of Shalott @ Wikipedia Including nearly 2500 people with autism including over 2100 males and 304 females, examining ........

Non-drug approaches for people with fibromyalgia

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

No-one wants to be told their pain is “in your head”. But given our increasingly sophisticated understanding of pain neurobiology, there’s plenty of reason to agree that thinking, feeling and doing things differently makes life far more rewarding and rich than feeling helpless, fatigued and sore. Some proponents of purely biomedical interventions, notably musculoskeletal physicians, argue that if only the “source of the nociception” was found, the nerve “zappe........ Read more »

I carry my son's DNA: a look at microchimerism and its effects

by EE Giorgi in CHIMERAS

To celebrate the upcoming release of my detective thriller CHIMERAS, the next few Research Blogging posts will be dedicated to the different forms of chimerism. I'm sure you are all familiar with dispermic chimeras, which occur when two fertilized eggs fuse together shortly after conception. The result is one individual with two sets of genetically distinct cells. Have you ever heard of microchimerism, though?"Microchimerism refers to a small number of cells (or DNA) harbored by one individual t........ Read more »

Dioxin exposure and autistic traits?

by Paul Whiteley in Questioning Answers

As promised in a previous post, today I'm turning my attention to the paper by Muneko Nishijo and colleagues [1] and their conclusion of "a specific impact of perinatal TCDD [2,3,7,8-tetrachlorodibenzo-p-dioxin] on autistic traits in childhood, which is different from the neurotoxicity of total dioxins (PCDDs/Fs) [polychlorinated dibenzo-p-dioxins/furans]".TCDD @ Wikipedia With all the recent chatter about [surrogate] environmental markers and the numbers ........

My thoughts on the dyslexia debate

by Dorothy Bishop in bishopblog

Elliott and Grigorenko have argued that dyslexia is not a meaningful category, and that the label should be abandoned because it just leads to unfairness and woolly thinking. I put this debate into the wider context of psychiatric diagnosis and argue we need to consider not just scientific evidence, but also how labels affect our judgements of who is deserving of help, and who is responsible for giving it....

Low Vitamin D, Atherosclerosis and CardioVascular Disease

by AB Kirk in Stiff Competition

Vitamin D has received tremendous interest over the last ten years.  One of the many things to come out about Vitamin D is that is that it protects against vascular calcification.  Vascular calcification causes or contributes to: Stiff arteries Poor elasticity Increased blood pressure Kidney damage Increased risk of heart attack and stroke Congestive heart […]

Environmental exposure and autism continued

by Paul Whiteley in Questioning Answers

In a post not-so-long-ago I talked about the paper by Andrey Rzhetsky and colleagues [1] and their assertion that environment (various facets of environment) might correlate with the increasing numbers of cases of autism being diagnosed. As per what was said on that post, there were lots of media headlines generated about the findings; some balanced and some a little sensational.Luc Viatour / www.Lucnix.be @ Wikipedia One of the main caveats I had with the Rzhetsky study was the relian........

Video Tip of the Week: ICGC portal for cancer genomics

by Mary in OpenHelix

A question at Biostar about cancer “gene sets” recently got me looking at one of my favorite data sources again–the ICGC, International Cancer Genome Consortium, and their data portal. Previous posts we’ve done were based on their legacy portal (which is still available on their site). They changed things up a bit with a release […]... Read more »

Short Sleep Duration in Children with Autism

by William Yates, M.D. in Brain Posts

Parents of children with autism and autism spectrum disorder commonly report sleep problems in their child.However, there have been few prospective systematic studies of sleep in this disorder.Joanna Humphreys from Canada and colleagues from England recently published an important manuscript addressing this topic.They used data from the Avon Longitudinal Study of Parents and Children. This data set includes prospective data collected from a cohort of over 14,000 children born between April 1991 ........ Read more »

Deleting The ‘I’ From CIAP

Soy infant formula and seizures in autism

by Paul Whiteley in Questioning Answers

Spring @ Wikipedia 'Association' is a word I'm sure many people with a connection to autism will have heard a lot about. Y'know gene X or compound Y is the plat du jour when it comes to autism aetiology; more often than not carrying the caveat 'requires further investigation'. As to whether such investigations are ever truly carried out would perhaps be an interesting piece of research on autism research.Today I'm talking about another association, another variable to throw into the st........

Brain Gray Matter Volumes in Primary Insomnia

by William Yates, M.D. in Brain Posts

Chronic primary insomnia is a sleep disorder characterized by delayed sleep onset, reduced total sleep duration and fatigue on morning awakening.In addition, by definition chronic primary insomnia cannot be due to a primary medical or psychiatric disorder. Some patients with chronic primary insomnia also demonstrate subjective and objective impairment in concentration and memory.Eun Yeon Joo and colleagues from South Korea recently published an analysis of brain structural features in 27 su........

Obesity and autism (again)

by Paul Whiteley in Questioning Answers

The paper by Phillips and colleagues [1] looking at the prevalence of 'unhealthy weight' in relation to developmentally-defined conditions including autism brought me to writing this update post on the topic of obesity and autism. As you might glean from that previous sentence, obesity and over-weightness(?) has been talked about before on this blog (see here and see here for example). My recent discussion in relation to findings of elevated plasma leptin in cases of autism (see here) ........ Read more »
