Gambler Sub-types: Three Distinct Profiles

by William Yates, M.D. in Brain Posts

One method to advance understanding of a disorder is to use statistical modeling for sub-type or class analysis.Lia Nower and colleagues recently published the results of such an analysis from the large general population data-set known as the U.S. National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).In this sample, 851 adults 18 years and older were identified with disordered gambling.This group then underwent a type of latent class statistical analysis known as the Pathways........

by Nura Rutten in United Academics

Compared to the beginning of the sitcom-area, in the 1950′s/1960′s, the roles of women and men sometimes seem to be reversed. However, in every sitcom, the woman who wants to be funny has only two options.... Read more »

Managers, conservatives, Europeans and the non-religious show higher levels of psychopathic traits

by BPS Research Digest in BPS Research Digest

Christian Bale played the archetypalpsychopath in American Psycho (2000).Mention psychopathic personality traits and the mind turns to criminals. The archetype is a callous killer who entraps his victims with a smile and easy charm. However, recent years have seen an increasing recognition that psychopathic traits are on a continuous spectrum in all of us (akin to other personality factors like extraversion), that they don't always manifest in criminality, and that in certain contexts, they may ........

Minocycline for schizophrenia?

by Paul Whiteley in Questioning Answers

"Minocycline may improve the psychopathology of schizophrenia, especially the negative symptoms, and seems to be well tolerated".A Bachelors Drawer (apparently) @ Wikipedia That was the finding from the systematic review and meta-analysis undertaken by Oya and colleagues [1] looking at the collected literature on the use of "minocycline augmentation therapy in patients with schizophrenia receiving antipsychotic agents". Augmentation therapy by the way, refers to the addition of minocycline ........ Read more »

The Learning Brain Unravelled

by Gabriel in Lunatic Laboratories

As an engineer you would think math would come easy to me, it didn’t. Funny thing though, science in general and biology in particular came very easy to me. The big question is why? Why would math, something I need to know how to do for my work and my degree, be so hard to learn? Thankfully science has stepped in to answer the question, at least partially, about why somethings can come so easy to a person and other things (like me and math) take so much longer to pick up.[…]...

Diagnostic Profile in Pathological Gamblers

by William Yates, M.D. in Brain Posts

Behavioral disorders like pathological gambling (PG) rarely occur alone as a single uncomplicated disorder.In a previous post, I noted the overlap of PG with personality disorder, anxiety disorder, depression, bipolar disorder and substance abuse.A recent study from Germany adds to our knowledge of the general diagnostic profile in the PG population.Erbas and Buchner reviewed German national data sources and other German studies to come up with a series of findings:Twelve month prevalence rates ........

Video Tip of the Week: Phenoscape, captures phenotype data across taxa

by Mary in OpenHelix

Development of the skeleton is a good example of a process that is highly regulated, requires a lot of precision, is conserved and important relationships across species, and is fairly easy to detect when it’s gone awry. I mean–it’s hard to know at a glance if all the neurons in an organism got to the […]... Read more »

Co-Chaperone Keeps Close Watch on Mice Sperm Production

by Christina Szalinski in ASCB Post

Chaperones aren't just for high-school homecoming dances. Cells have chaperones as well, chaperone proteins that ensure newly made proteins are properly folded. If protein folding goes awry, diseases associated with misfolded proteins such as Alzheimer's and Parkinson's can arise. But if one set of chaperones can throw a wet blanket on a school dance, imagine a second set of co-chaperones just to keep the chaperones in check. That's the growing picture in cellular chaperoning........ Read more »

Let’s Chew The Fat

by Mark Lasbury in As Many Exceptions As Rules

If vegetables are low fat, how can we make cooking oils from them? The key is that vegetable oils aren’t really vegetable oils- they’re fruit oils. In some plant fruits, the fats are sued to entice animals to eat them and disperse seeds. In other, the fats are used to provide energy for the embryonic plants. New research is showing that some plant oils have unique uses. A 2014 study shows that avocado oil is as good or better at stabilizing biochemical markers in patients with metabo........ Read more »

Just how diverse is this group, really?

by Doug Keene in The Jury Room

We often make assumptions when discussing diversity that we all perceive a group’s diversity in the same way. Today’s research shows that simply isn’t so. That is, you and I (depending on our racial in-group) can look at the same group and you might say it is diverse while I say it is not. What […]

Prenatal SSRI exposure and autistic traits

by Paul Whiteley in Questioning Answers

A quote to start today's post: "Our results suggest an association between prenatal SSRI exposure and autistic traits in children". That was a primary finding reported by Hanan El Marroun and colleagues [1] who looked at whether maternal depressive symptoms or a class of quite commonly used pharmaceutics - the selective serotonin reuptake inhibitors (SSRIs) - used to manage depressive symptoms, during pregnancy might impact on offspring development."Everything the light touches is our kingd........

Needles in a haystack: questioning the “fluidity” of ELF

by Ray Carey in ELFA project

As I’ve earlier argued on this blog, sometimes the claims of “fluidity”, “diversity”, and “innovation” found in English as a lingua franca (ELF) research are overstated. It’s so diverse that even ordinary diversity won’t do – it’s “super-diversity” now. It could very well be ultra-mega-diversity-squared, but the question of the prominence of these presumably innovative […]... Read more »

Narcotics Anonymous for military veterans

by DJMac in Recovery Review

A few years back in a city far, far away, I asked a consultant addiction psychiatrist why he did not refer any of his patients to NA. “There’s not a shred of evidence that it works,” he said. Even then he was misinformed, but I’ve thought many times since then about how his patients were [...]

August 26, 2014

by Erin Campbell in HighMag Blog

If you have little ones in your house, you might assume that the phrase “randomly fluctuating forces” is referring to your home. This phrase actually refers to the background force in a cell coming from active and motor-driven cell processes. Today’s image is from a study that developed a way to measure these forces. Actin- and microtubule-based motors move many types of material around a cell to drive critical cellular events. These motor-driven movements and other active processe........ Read more »

The Holographic Universe [we might Live in!]

by Gabriel in Lunatic Laboratories

Are you feeling a little… flat? Well that might be because you are only in 2 dimensions. I know what you’re thinking, insane! Well first check the name of the business and second, check out the science. In fact, it may seem like a joke, but the math suggests that it could very well be true and with it could come a deeper understanding of the universe. Testing this hypothesis (which was first made in the late 90’s) has been harder to do than you might think, but that has now changed. We are........ Read more »
