Zinc and copper and autism

by Paul Whiteley in Questioning Answers

The paper by Li and colleagues [1] looking at serum copper (Cu) and zinc (Zn) levels in a group of participants diagnosed with an autism spectrum disorder (ASD) is the source material for today's post. Highlighting how "mean serum Zn levels and Zn/Cu ratio were significantly lower in children with ASD compared with normal cases... whereas serum Cu levels were significantly higher" the continued focus on the metallome in autism carries on at a pace. I should at this point out that I'm not in........ Read more »

Biospleen Helps Clean Blood to Prevent Sepsis

by Gabriel in Lunatic Laboratories

When a patient has sepsis Things can go downhill fast. A life-threatening condition in which bacteria or fungi multiply in a patient's blood -- sepsis is often too fast for antibiotics to help. But that's all about to change with the introduction of a new device -- inspired by the human spleen -- that may radically transform the way doctors treat sepsis.... Read more »

Need a Kidney? Lab Grown Kidneys Coming Soon!

by Gabriel in Lunatic Laboratories

Stem cells offered the promise of having a patents own organ grown to replace a failing or damaged one. Unfortunately the road to that future has been paved with seemingly insurmountable challenges. Thankfully now we are one step closer, researchers have addressed a major challenge in the quest to build replacement kidneys in the lab. Working with human-sized pig kidneys, the scientists developed the most successful method to date to keep blood vessels in the new organs open and flowing with blo........ Read more »

Inflammation of the Brain and Memory Problems

by Gabriel in Lunatic Laboratories

Neurological disorders typically involve memory issues. Most of the problems are attributed to plaques that build up in the brain (which are typically prions), yet some causes are unknown. New research however sheds some light on at least one cause of memory problems. As it turns out brain inflammation can rapidly disrupt our ability to retrieve complex memories of similar but distinct experiences.... Read more »

Insulin, growth hormone and risk of schizophrenia?

by Paul Whiteley in Questioning Answers

"Overall, the present findings suggest that metabolic and hormonal disturbances such as effects on insulin and growth hormone may represent a vulnerability factor to develop mental disorders". That was the conclusion reported by van Beveren and colleagues [1] (open-access) looking at "disruption of insulin and growth factor signaling pathways as an increased risk factor for schizophrenia"."Years ago you served my father in the Clone Wars"Drawing on data derived from participants taking part in&n........

A cancer survivor is defined as anyone who is living with cancer, or whose cancer has gone into remission. Traditionally cancer care has concentrated on diagnosing and treating the disease, and comparatively little support has been given to patients once … Continue reading →... Read more »

September 11, 2014

by Erin Campbell in HighMag Blog

As your therapist likely tells you, understanding where you came from is key to accepting where you are now. Take that therapist’s task and multiply it by several million—you now understand the tough job ahead of developmental biologists trying to track cell lineages in complex organisms. Today’s colorful image is from a paper describing a new computational framework for reconstructing cell lineages. The successful tracking of cell position, division, and movement in a developing or........

SARS-CoV: formation of the RTC and mitophagy; role of p6 and orf9b

by thelonevirologist in Virology Tidbits

Whilst the nature of the RTC and the role of the CoV non-structural proteins as well the potential role of these proteins in the ER stress response have been discussed in detail before, the role of p6 has been not been discussed. p6 not only induces the formation of membranous vesicles but also recruits nsp-8 to nsp-5, the main viral RNA Polymerase, and induces a ER stress response.
Also the role of SARS-orf9b in the induction of mitophagy is discussed.... Read more »

The Origami Brain and a new marker for Schizophrenia

by Gabriel in Lunatic Laboratories

Anyone who has seen pictures or models of the human brain (like the one above) is aware that the outside layer, or cortex, of the brain is folded in an intricate pattern of “hills”, called gyri, and “valleys”, called sulci which give the brain it’s distinctive look. It turns out that the patterns of cortical folding are largely consistent across healthy humans, broadly speaking. However, disturbances in cortical folding patterns suggest deeper disturbances in brain structure and functi........ Read more »

Treating autism in the first year of life

by Paul Whiteley in Questioning Answers

I had been waiting y'know. Waiting a while for the paper by Sally Rogers and colleagues [1] to finally appear quite a few days after the media headlines about 'reducing', 'reversing' and even 'eliminating' the signs and symptoms of autism in early infancy had appeared. Personally, I prefer the New Scientist headline: 'Early autism intervention speeds infant development' given the text of the paper. I should perhaps also add the words 'for some' to that sentence as you will hopefully see...I........ Read more »

Stop Worrying, Good-Looking Dudes: Your Sperm Is Fine

by Elizabeth Preston in Inkfish

You may have seen headlines over the past week proclaiming that handsome men have lower-quality sperm. If this made you panic because you happen to be a great-looking guy, you can stop. (If you’re an un-handsome man who’s been gloating—sorry.) This scientific study did say a few interesting things about Spaniards, Colombians, and cheekbones.

Omega-3 fatty acids rescues Fragile X phenotypes in Fmr1-Ko mice

by Paul Whiteley in Questioning Answers

"These results demonstrate that n-3 PUFAs dietary supplementation, although not a panacea, has a considerable therapeutic value for FXS [Fragile X syndrome] and potentially for ASD [autism spectrum disorder], suggesting a major mediating role of neuroinflammatory mechanisms".A view @ Wikipedia That was the conclusion reached by Susanna Pietropaolo and colleagues [1] who "evaluated the impact of n-3 PUFA dietary supplementation in a mouse model of fragile X syndrome ........

Multiple Sclerosis and Myelin loss

by Gabriel in Lunatic Laboratories

Multiple sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body. The exact cause is unknown, however people with multiple sclerosis lose myelin in the gray matter of their brains and the loss is closely correlated with the severity of the disease, according to a new magnetic resonance imaging (MRI) study....

Apple Does 3D Cell Culture

by Nicholas Miliaras in ASCB Post

Andrew Pelling has a new application for the apple, but it is not the latest i-gizmo from Cupertino, CA. Pelling and colleagues at the University of Ottawa have come up with a possible solution to the limitations of traditional, two-dimensional (2D) cell culture, which does not reproduce the microenvironment and tissue architecture that surrounds cells in a living organism—the apple, the one-a-day fruit that keeps the doctor away and is an essential ingredient to the All-American pie.

Video Tip of the Week: #Docker, shipping containers for software and data

by Mary in OpenHelix

Breaking into the zeitgeist recently, Docker popped into my sphere from several disparate sources. Seems to me that this is a potential problem-solver for some of the reproducibility and sharing dramas that we have been wrestling with in genomics. Sharing of data sets and versions of analysis software is being tackled in a number of […]... Read more »

Return of Results from Next-gen Sequencing

by Daniel Koboldt in Massgenomics

The rapid adoption of next-gen exome and genome sequencing for clinical use (i.e. with patient DNA) raises some difficult questions about the return of results to patients and their families. In contrast to traditional genetic testing, which usually checks for variants in specific genes, high-throughput sequencing has the potential to reveal a number of secondary […]... Read more »

Bacteria Can Really Get Around

by Mark Lasbury in As Many Exceptions As Rules

Bacteria have evolved a type of motion that is a lot like a snot-powered rocket, so getting from point A to point B must be pretty important. Bacteria have evolved no fewer, and probably a lot more, than eight different ways to move around. New research is defining the physics and molecular biology of these modes of transportation, including a pseudo-cytoskeleton, helical conveyor belts, and something called “reverse and flick.”...
