Virtual Reality for Treatment of PTSD
by Dr Shock in Dr Shock MD PhD
Three fast track articles were recently published on CyberPsychology and Behavior about the treatment of PTSD with virtual reality exposure therapy. Exposure therapy is the most evidence based treatment for Post Traumatic Stress Disorder (PTSD). More than 18 studies have been published on the use of virtual reality exposure treatment for PTSD.
One of [...]

Getting through it
by Adiemusfree in Healthskills: Skills for Healthy Living
Some of you may know that I’ve just had surgery, and I’m gently recovering from the comfort of my own home over the next few weeks. Posts on here will be intermittent but I find myself considering aspects of pain management from a ‘patient’s’ perspective today as it’s about 5 days since surgery and my [...]... Read more »

Probable vCJD in an individual who was heterozygous at codon 129 of PRNP
by Brian Appleby in CJD Blogger
This week’s Lancet features an article entitled, “Variant CJD in an individual heterozygous for PRNP codon 129” by Kaski and colleagues. The authors report the first case of probable variant Creutzfeldt-Jakob disease (vCJD) in an individual who is heterozygous at codon 129 of the prion protein gene (PRNP). To date, all symptomatic cases have occurred in individuals who are homozygous for methionine at codon 129. As we know from other studies (Brown P, 1994), the incubatio........ Read more »

Two Drugs Are Better Than One?
by Neuroskeptic in Neuroskeptic
According to a study just out in the American Journal of Psychiatry, starting depressed people on two antidepressants leads to much better results than starting them on just one - Combination of Antidepressant Medications From Treatment Initiation for Major Depressive Disorder. But how reliable is it?Currently accepted practice is to prescribe one antidepressant to begin with, and if the patient doesn't feel better after about 6 weeks, to either change to a different antidepressant (switching) o........

Is Time on Your Side?
by Shaheen Lakhan in Brain Blogger
Physicians are under mounting pressure to increase efficiency in the provision of medical care. That is, see more patients in less time for less money. But, since speed and accuracy do not always go hand-in-hand, does this increased physician efficiency lead to quality medical care?

Scientists wrestling with DNA repair find a new role for SUMO
by Cancer Research UK in Cancer Research UK - Science Update
Despite their heavyweight name, SUMO proteins are a family of small proteins found in our cells, which, by sticking to other proteins, can regulate all sorts of cellular goings-on.
For example, sticking a SUMO protein onto another protein can shuttle it to a different location in the cell, or alter how it works.
And there’s tantalising evidence [...]... Read more »

It’s been a bumper week for cancer research. As we report elsewhere, scientists have been delving deep into our cells’ DNA repair mechanisms, and finding out how they tick.

Too Much TV Reduces the Benefits of Physical Activity
by Travis Saunders, MSc in Obesity Panacea
One of my personal interests is the relationship between sedentary time (e.g. the amount of time that we spend sitting) and chronic disease risk. Several interesting papers have come out in the past few years suggesting that spending too much time sitting down is a risk factor for obesity, chronic disease, and even death, independent of physical activity levels. In other words, no matter how physically active you are, the more time you spend sitting, the greater your risk of death and disease......... Read more »

Personality Traits and Political Attitude

The relationship between personality and political preferences is not the simple relation between conservatism and negative personality traits on the one hand and liberalism and positive personality traits on the other hand. Personality is understood as the combination of innate dispositions and personal experiences that guides behavior in a stable and predictive manner. Behavior is [...]

Methuselah's Zoo
by Reason in Fight Aging!
Is the research community doing as much as it might to extract value from the diversity in life span amongst mammals? Certainly there are those scientist who would like to be engaged in a great deal more sequencing and biochemical deciphering of long-lived animals. But on the whole, I think that less is taking place in this area of study than might be. See this paper from a noted gerontologist, for example: As impressive as the accomplishments of modern molecular biologists have been in finding ........ Read more »

The Neurobiology of Love
by Dr Shock in Dr Shock MD PhD
Previously we discussed the neurobiology of falling in love. But this is only the beginning, the process of attraction followed by the attachment process. This process can develop and last for a while or in some cases for ever. Biologically is falling in love the first step in pair formation.

Zicam and your Nose

Weight in the Workplace

Are Cells From Old People Still Good For Therapeutic Use?
by Reason in Fight Aging!
Some nagging uncertainties remain on progress in stem cell medicine - and especially progress in reprogramming easily obtained somatic cells into patient-specific pluripotent stem cells. These uncertainties will be answered and addressed in the years ahead, but this one springs to mind today: it is possible that cells from older people may be altered or damaged in ways that prevent their effective use as-is in the sort of autologous stem cell therapies presently envisaged. That would be a setbac........ Read more »

Obese, But Metabolic Healthy Individuals: at Lower Risk for Death

Yet another bad day for the anti-vaccine movement
by Orac in Respectful Insolence
Arguably, the genesis of the most recent iteration of the anti-vaccine movement dates back to 1998, when a remarkably incompetent researcher named Andrew Wakefield published a trial lawyer-funded "study" in the Lancet that purported to find a link between "autistic enterocolitis" and measles vaccination with the measles-mumps-rubella (MMR) trivalent vaccine. In the wake of that publication was born a scare over the MMR that persists to this day, 11 years later. Although peer reviewers forced the........ Read more »
