Seeing Red: A New Way To Predict Preeclampsia

by Rebekah Morrow in United Academics

New Congo red test predicts development of preeclampsia with pregnant women. A large collaboration of scientists recently reported a new method of determining which women would develop preeclampsia. Urine samples were collected from more than 600 patients and mixed with a dye called Congo red. Congo red stains large clumps of proteins, but doesn’t mark smaller separate proteins.... Read more »

Trauma and PTSD raise risk of autoimmune disorders?

by Paul Whiteley in Questioning Answers

I admit to some head scratching when I first read the paper by Aoife O’Donovan and colleagues [1] reporting that among war veterans of the Iraq and Afghanistan campaigns, "trauma exposure and PTSD [post-traumatic stress disorder] may increase risk of autoimmune disorders".It wasn't that I didn't believe the results, but rather that the idea that a physical event with a psychological consequence could impact on a somatic condition with an autoimmune element to it seemed to open u........

Fasting Improves Recovery of Bone Marrow Stem Cells after Chemotherapy

by Jalees Rehman in The Next Regeneration

Fasting is defined as either completely abstaining from or minimizing food intake for a defined period time - ranging from about 12 hours to even a few weeks. Calorie restriction, on the other hand, refers to an overall reduction in the daily calorie intake by about 20%-40% without necessarily reducing the meal intake frequency. Although calorie restriction is well-suited for weight loss and thus also reduces the risk of chronic diseases such as diabetes or heart disease, proponents of fasting c........ Read more »

Common variation and the genetics of autism

by Paul Whiteley in Questioning Answers

The paper by Trent Gaugler and colleagues [1] reporting that the genetic architecture of the autism spectrum disorders (ASDs) seems in the most part to be due to "common variation" over and above "rare variants or spontaneous glitches" adds to the quite voluminous literature in this area.Everything in proportion? @ Wikipedia Based on an analysis of "a unique epidemiological sample from Sweden" researchers looked at DNA variations in some 3000 individuals with autism and asymptomatic co........

Autism and asthma yet again

"Asthma is approximately 35 % more common in autistic children".Pipe down @ Wikipedia That was the finding reported by Stanley Kotey and colleagues [1] based on their analysis of the 2007 National Survey of Children's Health (NSCH) dataset, a resource looking at "the physical and emotional health of children ages 0-17 years of age" resident in the United States.

Bacterial CRISPRs: Not Just For Targeting Foreign Nucleic Acids

by Geoffrey Hannigan in Prophage

In recent years, CRISPRs (Clustered, regularly interspaced, short palindromic repeats) have been gaining popularity in the microbiology field. Briefly, CRISPRs serve as an adaptive immune system for bacteria, meaning that they are able to remember what viruses (bacteriophages) or other entities have infected them and mount a targeted defensive response the next time they are infected with the same entity (think of it as an analog to our adaptive immune response which uses antibodies and other a........

What makes a cancer a cancer? The Hallmarks of Cancer

by Robb Hollis in Antisense Science

Cancer – the ‘C word’ in far too many of our lives. Wherever you are, it’s unlikely you’ll be able to avoid the news reports and personal stories about people fighting against cancer. Understanding how the disease occurs and how it takes hold over the body is key for developing effective new treatments and managing patients in the clinic, and so huge amounts of money are invested in cancer research every year. But what actually is cancer and how does it develop?... Read more »

Ultrafine particulate matter air pollution, mice and autism

by Paul Whiteley in Questioning Answers

Reading the headline "Study links air pollution to autism, schizophrenia" in a media piece about the study by Joshua Allen and colleagues* (open-access here) made me want to delve a little more into this research. I've talked before about air pollution and autism (see here) on this blog. Although a healthy degree of scepticism is to be expected with any autism correlation, particularly when it comes to something as generalised as air pollution (or pesticide exposure) there is a growing rese........
