A 'characteristic chemical signature' to chronic fatigue syndrome?

by Paul Whiteley in Questioning Answers

Today I'm (belatedly) talking about the paper by Robert Naviaux and colleagues [1] (open-access) and some further peer-reviewed discussion concerning the metabolomics of chronic fatigue syndrome (CFS). Suggesting that "targeted, broad-spectrum metabolomics of plasma not only revealed a characteristic chemical signature but also revealed an unexpected underlying biology" when it comes to CFS, it is not surprising that this work has attracted some media interest (indeed, quite a lot of m........

Learning to turn down your amygdala can modify your emotions

by Dr. Jekyll in Lunatic Laboratories

Training the brain to treat itself is a promising therapy for traumatic stress. The training uses an auditory or visual signal that corresponds to the activity of a particular brain region, called neurofeedback, which can guide people to regulate their own brain activity. However, treating stress-related disorders requires accessing the brain's emotional hub, the amygdala, which is located deep in the brain and difficult to reach with typical neurofeedback methods.

Opioid Abuse: Treatment Guidelines

by William Yates, M.D. in Brain Posts

Molecular model of the drug buprenorphineThe U.S. Surgeon General recently sent a letter to all physicians about the danger of prescription opioids, particularly when used in combination with benzodiazepines (i.e. Valium, Xanax).  This combination greatly increases the risk of overdose death.Clinicians can successfully assist those with opioid use disorders. Marc Schuckit, M.D. recently published a nice summary review of entitled "Treatment of Opioid-Use Disorder" in the New England Journal........ Read more »

The force is strong with autism?

by Paul Whiteley in Questioning Answers

"Tablet and phone games could help diagnose autism, study suggests" went the BBC headline covering the paper by Anna Anzulewicz and colleagues [1] (open-access). The idea being that the way that touch screens are used on tablet and smart phones could potentially 'separate out' those with autism from those with not-autism.Based on a small participant number of "37 children 3–6 years old with autism and 45 age- and gender-matched children developing typically" researchers set about examinin........

A microRNA plays role in major depression

by Dr. Jekyll in Lunatic Laboratories

A tiny RNA appears to play a role in producing major depression, the mental disorder that affects as many as 250 million people a year worldwide. Major depression, formally known as major depressive disorder, or MDD, brings increased risk of suicide and is reported to cause the second-most years of disability after low-back pain.

Social connectedness can increase suicide risk

by Dr. Jekyll in Lunatic Laboratories

Community characteristics play an important role in perpetuating teen suicide clusters and thwarting prevention efforts, according to a new study by sociologists who examined clusters in a single town. The study illustrates how the homogeneous culture and high degree of social connectedness of a community can increase suicide risk, particularly among teenagers.

Prevalence of self-injurious behaviors among children with autism

by Paul Whiteley in Questioning Answers

Just over a quarter of children diagnosed with an autism spectrum disorder (ASD) present with self-injurious behaviour (SIB).That was the headline finding reported by Gnakub Soke and colleagues [1] who surveyed the 8000+ children "in the Autism and Developmental Disabilities Monitoring (ADDM) Network during the 2000, 2006, and 2008 surveillance years." THE ADDM network, as some people might know, is one and the same network that comes up with the [estimated] prevalence of autism in the Unit........ Read more »

Statin Therapy: Rethinking Benefits and Risks

by William Yates, M.D. in Brain Posts

A recent 30-page manuscript provides an exhaustive review of the evidence for the efficacy and safety of statin therapy.The authors of this excellent review provide some context for the relative value of statins.The note that putting 10000 individuals with a history of a vascular event on a statin drug for 5 years would prevent 1,000 subsequent events. This is an example of secondary prevention--preventing another adverse outcome in those already experiencing an adverse event.But the statin drug........ Read more »

C9orf72-SMCR8 complex, analogous to FLCN- FNIP, localizes to lysosomes and regulates mTORC1

by Joana Guedes in BHD Research Blog

The DENN protein module contains a longin domain, a DENN domain and a d-DENN domain. Nookala et al. (2012) identified a DENN module in folliculin (FLCN), the Birt-Hogg-Dube tumour suppressor. The DENN module is believed to be a GEF for Rab-GTPases, although FLCN is believed to act as a GAP for RagC (Tsun et al., 2013) as is its yeast homologue, LST7, in interaction with the yeast FNIP homologue Lst4 (Pacitto et al., 2015). A recent bioinformatic study identified DENN domains in several other ........ Read more »

Predicting protein function: what’s new?

by Iddo Friedberg in Byte Size Biology

Long time readers of this blog (hi mom!) know that I am working with many other people in an effort called CAFA: the Critical Assessment of protein Function Annotation. This is a challenge that many research groups participate in, and its goal is to determine how well we can predict a protein function from its amino-acid sequence. The first CAFA challenge (CAFA1) was held in 2010-2011 and published in 2013. We learned several things from CAFA1. First, that the top ranking function prediction pro........ Read more »

Post-exertional malaise (PEM) in CFS might mean more than one thing

by Paul Whiteley in Questioning Answers

"The results suggest that post-exertional malaise [PEM] is composed of two empirically different experiences, one for generalized fatigue and one for muscle-specific fatigue."So said the findings reported by Stephanie McManimen and colleagues [1] looking at one of the most common and debilitating aspects of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) and how rough-and-ready generalised descriptions often do little to reveal the complexities of this particular sympt........
