Vaccine against prion disease, not for humans… yet

by Gabriel in Lunatic Laboratories

Prions, misfolded proteins that wreak havoc on the brain, may have finally met their match. Best known for things like mad cow disease and possibly alzheimer’s disease scientists have had no luck stopping prions, until now. Researchers say that a vaccination they have developed to fight a brain-based, wasting syndrome among deer and other animals may hold promise on two additional fronts: Protecting U.S. livestock from contracting the disease, and preventing similar brain infections in humans....

Vitamin D for autism... a double-take?

by Paul Whiteley in Questioning Answers

Yes, I know. Another post on the 'day of rest' but I promise you that this will not become a habit. The reason: the paper by Feiyong Jia and colleagues [1] published in the premier journal Pediatrics. The authors describe a case report of a young child with autism who is observed to have shown improvement in some of the core symptoms of autism following supplementation with the [sunshine] vitamin/hormone of the hour: vitamin D. Further reporting on the paper can be seen here.Although the paper is interesting - "stressing the importance of clinical assessment of vitamin D3 deficiency and the need for vitamin D3 supplementation in case of deficiency" - and fits in well with my borderline obsession with vitamin D, my interest was piqued because we have actually seen something similar from this research group before [2]. On this and that occasion, 'possibly' reporting on the same "32-month-old boy with ASD [autism spectrum disorder] and vitamin D3 deficiency". I've also discussed the previous Jia paper on this blog before (see here).I'm gonna say little more on this topic aside from reiterating my reiteration(?) on that previous post about Jia et al talking about their description of a single case report and how one has to be very careful about generalising to the very wide and very heterogeneous autism (or autisms). Yes, there may indeed be issues with vitamin D levels / availability when it comes to some people on the autism spectrum [3] (see here for example) but science is still feeling it's way around this topic and where such a finding might link into the grand scheme of things with a diagnosis of autism spectrum disorder in mind.I'm also minded to bring to your attention two other papers also appearing in the same journal and reporting with vitamin D in mind: Hart and colleagues [4] detailing more results from the Raine study on what maternal vitamin D levels might mean for offspring outcomes, and McNally and colleagues [5] (who has some research history with vitamin D in mind) talking about how to correct any deficiency. That all being said bearing in mind my prime [blogging] directive: no medical or clinical advice given or intended.Now, about that Sunday lunch...----------[1] Jia F. et al.

Antidepressants and the effects on your unborn child

by Gabriel in Lunatic Laboratories

Think you know what causes depression? Well unfortunately scientists don’t have the exact answer, surprised? That’s not the only problem, there is an ever growing concern that we live in an over medicated society and a newly released study doesn’t paint a better picture. About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants. However little is known about how early exposure to these medications might affect their offspring as they mature into adults.... Read more »

The Ethics of Joke Science

by Neuroskeptic in Neuroskeptic_Discover

What happens when scientists publish papers that aren't meant to be taken seriously? Is ironic, satirical and joke science all in good fun, or can it be dangerous?



This is the question asked by Drexel University researchers Maryam Ronagh and Lawrence Souder in a new paper is called The Ethics of Ironic Science in Its Search for Spoof.

The British BMJ journal is known for an annual Christmas special issue filled with unusual articles. For example, two years ago they explored the questio... Read more »

Joint hypermobility and links to psychiatry

by Paul Whiteley in Questioning Answers

"The relationship between JH/HDCT [joint hypermobility / heritable disorders of connective tissue] and mental disorders merits further attention in order to improve current knowledge and clarify a possible common etiology."There is nothing in the desert and no man needs nothing.That was the conclusion reached in the paper by Carolina Baeza-Velasco and colleagues [1] looking at the possibility of some interesting connections, outside of just physical presentation, when it comes to the range of conditions headed under the label 'disorders of connective tissue'. The list of diagnoses potentially 'associated' with JH/HDCT by Baeza-Velasco et al is pretty long: "anxiety disorders, depression, schizophrenia, neurodevelopmental disorders (autism, attention deficit/hyperactivity disorder [2], and developmental coordination disorder), eating disorders, personality disorders and substance use/misuse."From the point-of-view of this blog, mention of the word 'autism' is perhaps the most important suggested link, harking back to some previous discussion of joint hypermobility and gait with the autism spectrum in mind (see here). I'm still pretty interested in seeing this issue followed up in the autism research arena bearing in mind the possible influence of comorbidity as per findings related to the presence of anxiety and joint hypermobility [3] and the question of which comes first: autism or hypermobility?Music: Glow by Ella Henderson.----------[1] Baeza-Velasco C. et al.

Know your brain: Pituitary gland

by neurosci in Neuroscientifically Challenged







The pituitary gland (in red). Image courtesy of Life Science Databases (LSDB).






Where is the pituitary gland?The pituitary gland is a small (about the size of a pea) endocrine gland that extends from the bottom of the hypothalamus. It is divided into two lobes in humans, the anterior pituitary and posterior pituitary. The anterior pituitary does not have direct neural connections to the hypothalamus, but is able to communicate with it through a system of blood vessels called the hypophyseal portal system. The posterior pituitary, however, is directly connected to the hypothalamus by a tube-like structure called the infundibular stalk.What is the pituitary gland and what does it do?The pituitary gland is often referred to as the "master gland" of the body because it is responsible for the release of hormones that regulate the activity of other endocrine glands and bodily systems; in this way it affects physiological processes throughout the body. Despite its directorial appellation, however, the function of the pituitary gland itself is controlled by the hypothalamus.The anterior pituitary is responsible for the synthesis and secretion of a collection of hormones that have manifold effects in a number of different physiological systems. Some of these hormones, along with a very simplified description of their actions, are: adrenocorticotropic hormone, which prompts the release of glucocorticoid hormones like cortisol; beta-endorphin, which is involved in natural pain relief; thyroid-stimulating hormone, which prompts the release of metabolic hormones from the thyroid; follicle-stimulating hormone and luteinizing hormone, which are involved in the proper functioning of the reproductive system; growth hormone, which promotes growth; and prolactin, which is involved in milk production in females. Of course the roles of each of these hormones is actually much more diverse and complex than this list indicates, but these are some of their best-known functions.The hypothalamus does not have neural connections with the anterior pituitary but it communicates with the gland via a system of blood vessels called the hypophyseal portal system. The hypothalamus secretes hormones called releasing hormones into the hypophyseal portal system; these hormones travel through the bloodstream to the anterior pituitary, where they act as signals to prompt the release of hormones like those listed above.The posterior pituitary is responsible for the release of two hormones: oxytocin and vasopressin. Unlike the anterior pituitary, however, the posterior pituitary does not synthesize its own hormones. Oxytocin and vasopressin are both synthesized in the hypothalamus, and then sent via neuroendocrine projections to the posterior pituitary. From there they are released them into the bloodstream. Oxytocin has roles in facilitating childbirth and lactation, but is also thought to play a role in promoting social bonding and compassion. Vasopressin, also known as antidiuretic hormone, is primarily involved in controlling urine output and regulating blood pressure.The pituitary gland is less than a centimeter in diameter, but it secretes hormones that have widespread effects on behavior and bodily function. Thus, despite its diminutive size it has justifiably earned the moniker of "master gland."Amar, A., & Weiss, M. (2003).

December 18, 2014

by Erin Campbell in HighMag Blog

You might not want the dreaded tube socks in your Christmas stocking this year, but you do appreciate the actual tubes that your body depends on in just about every organ system. A recent paper in PLOS Biology describes tube formation in the fly renal system and the signals that regulate it. Tubes generally start as buds that dramatically elongate during development, but the cell rearrangements that occur during tubulogenesis are not completely understood. Saxena and colleagues recently used the developing fly renal system to track cell movements during tube formation. Tubule elongation primarily occurs through convergent extension, during which cells intercalate along the length of the tube. During these rearrangements, the number of cells around the circumference of the tube drops as the number of cells along the tube increases. Saxena and colleagues show that epidermal growth factor localized at the tip cells of the distal end of the tube guides the polarity of cell rearrangements, via polarization of Myosin II within individual cells. Finally, without proper tube elongation, animals have abnormal excretory function and osmoregulation, leading to lethality. In the images above, the top row shows failure of tube elongation after laser ablation of the distal tip cells (arrowheads). Bottom row shows normal tube elongation without laser ablation of tip cells (arrowheads). Saxena, A., Denholm, B., Bunt, S., Bischoff, M., VijayRaghavan, K., & Skaer, H. (2014).

Why “fat shaming” makes the problem worse

by Gabriel in Lunatic Laboratories

Thanks to the internet age we have lost touch with the fact that there is a human out there reading these words. Because of this, the golden rule –treat others the way you want to be treated — went out the window. Making fun of “fat” people now seems to be a internet hobby and that insensitivity can (and does) bleed over into “normal” non-internet life. Now a new study shows that women whose loved ones are critical of their weight tend to put on even more pounds, which is probably no surprise to people who have experienced this behavior....

The Chemistry of Christmas

by Melissa Chernick in Science Storiented

What are the sights, the sounds, the smells, and the textures that you associate with Christmas? Perhaps it is Christmas trees with their lovely green shape, color and wonderful pine smell. Maybe it’s the smells of cooking, the savory smells of turkey or the sweet smell of warm cookies. Or what about all of the cozy feelings you get with big sweaters or a roaring fire? Did you know that there is a lot of chemistry that goes into all of the senses we associate with this holiday?I was browsing through holiday-related articles, looking for something different from the usual psychology or sociology centered holiday study. That’s when I came across an article from 2012 published in the Journal of Chemical Education about the five senses of Christmas chemistry. The authors look through the lens of organic chemistry and take five “Christmas compounds” to examine in the context of the five senses.Sound: Silver FulminateIn 1824, Justus Liebig correctly determined the molecular formula of silver fulminate (AgCNO), and, around the same time, Friedrich Wohler identified the molecular formula for silver cyanate (AgOCN). Now, these might look the same, but they are in fact very different. Soon after, these scientists collaborated and rationalized these differences by introducing the notion of isomerism – molecules that have the same kinds of atoms but because these atoms have different arrangements in shape they differ in their chemical and physical properties. Silver fulminate is highly unstable, and even a small amount of friction leads to its violent decomposition. That makes it very useful when you want to make things go boom.Christmas crackers are items that are a more traditional favorite in the UK. The Christmas crackers used today are short cardboard tubes wrapped in colorful paper. When they are pulled – bang! – out comes a colorful hat (usually looking like a crown), a small toy or a joke. The sound is made from the rapid breakdown of silver fulminate present in small quantities in the paper. Two thin strips of cardboard are glued together, one containing silver fulminate and the other a rough surface. When the cracker is pulled, the surfaces rub together to produce friction and facilitate the reaction. The compound goes through a redox reaction followed by a release of nitrogen gas and carbon monoxide. This sudden production of gases is what produces the distinctive popping sounds.Sight: α-pineneA beautifully lit and decorated Christmas tree is one of the most common sights of this holiday. For the purposes of this section, we’ll assume that you bought a real tree rather than an artificial one. Geographic region can play a big part in the species of tree that is available to you, but they are very likely all evergreens (fir, spruce, pine, and cedars). In their resin, these conifers release terpene hydrocarbons, specifically monoterpenoids that is composed of two isoprene building blocks. This word should sound familiar as it is a derivative of turpentine, which you may know for its distinctive pine scent. Pine oil contains two monoterpenoids, α-pinene and β-pinene, which are both liquid at room temperature. This is another case of isomerism; although both have the typical C10H16 molecular formula there are four stereoisomers of each where the bonded atoms differing in their 3-D orientations. α-pinene is one of the most common volatiles in nature and is directly linked to the Christmas tree’s smell. Touch: Sodium Acetate I don’t live in what most people would term a cold climate. Sure, we get cold weather, but we’re not talking blizzards. However, in my days as a field ecologist I spent many a winter day outside taking measurements. On those days, I was ever-so-grateful for one little invention: the hand warmer. Squish around the contents of the packet to get it to heat up to keep you pockets, and hands, toasty all day long. Bliss.Many hand warmers are based on a simple chemical reaction – the crystallization of a supersaturated sodium acetate solution. When you squish around the contents of the hand warmer, you are triggering a chemical process. A nucleation site, usually a metal disk with small seed crystals, causes rapid crystallization of the super saturated solution. This is a highly exothermic process that releases energy to its surroundings as heat. These types of hand warmers are often reusable because of their physical mode of action. Other hand warmers rely on the exothermic oxidation of iron when exposed to air. Activated charcoal is used to catalyze the reaction, along with vermiculite and salt as additives. However, this chemical mode of action means that these are one use only products.Taste: TryptophanIf you are a fan of a big turkey dinner then you have probably heard of tryptophan. It is a common misconception that the tryptophan from your turkey binge brings on sleepiness. It’s true that tryptophan is involved in sleep and mood control. However, turkey doesn’t contain enough of the compound (only 350 mg per 115 g) to have a soporific effect. It’s more likely that the sheer volume of food that you eat (and probably the wine you drank with it) on these occasions decreases blood flow and oxygenation, inducing the drowsiness.Tryptophan is an essential aromatic amino acid that is commonly found in proteins. This compound has two enantiomers, chiral molecules that are mirror images of one another (kinda like left and right hands). L-tryptophan exists in nature and has a pronounced bitter taste, while D-tryptophan is synthetic and has a very sweet taste. Once you consume tryptophan, it goes through a series of metabolic reactions, one of which ends with melatonin. This final product is a neurohormone that is naturally secreted by the pineal gland, is involved in regulating circadian rhythms and may also have strong antioxidant effects.Smell: GingerolGingersnap cookies and gingerbread houses are common sights around the holidays, and with them come their wonderful ginger scent. Ginger products usually contain fresh or powdered bits from the rhizomes (rootstalk, or modified underground stem) of the ginger plant (Zingiber officinale). One of the organic compounds produced by this plant is gingerol, an aromatic vanilloid compound containing a β-hydroxyketone functionality. Interestingly, the taste of this compound can be modified via laboratory synthesis. Shogaol is derived by either refluxing gingerol with concentrated sulfuric acid or allowing a dehydration reaction can occur on gingerol to give the aldol condensation product. Shogaol has a more pungent flavor than gingerol. Conversely, ginergol can completely break down into zingerone after refluxing in strong aqueous base. Zingerone is considered to have less pungency than gingerol.Considering this chemistry, you can alter the flavor of the ginger you use in your cooking. For example, if you cook ginger extensively, particularly in the absence of acid, then you produce the mildest tasting vanilloids, zingerone. But also keep in mind that your kitchen conditions are not laboratory conditions. This means that you are likely to end up with a mixture of all three compounds in your cookies.That’s all for our journey through the senses of Christmas. If you are a chemistry teacher, or simply a chemistry nut, then I recommend reading through the paper. It has all sorts of skeletal formulas that you’ll love.... Read more »

Dogs Not Great at Math (Wolves Are Better)

Head Motion Biases Brain Structural Scans

by Neuroskeptic in Neuroskeptic_Discover

A regular theme here at Neuroskeptic is the worrying issue of head movement during brain scans. We've seen that motion can alter measures of functional and structural connectivity, and that common approaches to dealing with this problem may be inadequate.


Now a new study reveals that even measures of the gross structure of the brain can be biased by excessive motion: Head motion during MRI acquisition reduces gray matter volume and thickness estimates.

The stench of compatibility: How otters identify one another, and potential mates by smelling their poop

by Denise O'Meara in Denise O'Meara

Otters don’t tend to be very visible to us, but they are more abundant than we might perceive them to be. Otters mostly live in isolation of one another, yet they manage to remotely communicate to one another without the aid of modern technology that we so often depend upon for communication.

On this blog, I previously wrote how otters communicate with one another using their spraints (faeces). They use them to mark their territory and to leave messages for other otters. As part of the research project I work on, we collect these spraints for DNA analysis to tell us about the population.

A new study by Eleanor Keane and colleagues at Cardiff University, published in Mammalian Biology has sought to understand some of these chemical messages. Keane explains in their study that “otters have two anal sacs, each of which deposits secretions with faeces (spraints)”.... Read more »

Uric acid and bipolar disorder

by Paul Whiteley in Questioning Answers

Bipolar disorder appearing again on this blog this week? It's just the way that the papers fall...With a title like: 'Increased uric acid levels in bipolar disorder subjects during different phases of illness' I was hardly likely to pass up the opportunity to discuss the paper by Umberto Albert and colleagues [1] and their suggestion that there may be a lot more to see when it comes to "a purinergic dysfunction associated with BD [bipolar disorder]".I lost the defuser gun when I misplaced the invisible car.Based on the analysis of serum uric acid (UA) levels in 150 participants formally diagnosed with BD compared with "150 age- and gender-matched subjects with MDD [major depressive disorder], OCD [obsessive compulsive disorder], or Schizophrenia", researchers reported that: "Mean serum UA levels (5.06±1.45 vs. 4.17±1.05mg/dL) and rates of hyperuricaemia (30.7% vs. 6.7%) were significantly higher in the bipolar than in the control group." The authors pointed out the limitations of their study: "Our study suffers from the lack of a healthy comparison group; moreover, longitudinal data are missing" so no need for me to say anything further in that respect.Uric acid, more commonly associated with a condition like gout, has been getting quite a bit of research attention when it comes to behaviour and psychiatry down the years. I've talked previously on this blog about the intriguing work suggestive of a possible connection between levels of uric acid and impulsivity (see here) highlighting a possible biology - trait connection. As per the Albert findings - "No differences were detected between bipolars in different phases of illness, with all three groups (manic, depressive and euthymic bipolars) showing significantly higher UA levels as compared to controls" - other research has hinted that the relationship between uric acid and BD is quite a bit more than just one related to trait [2]. I'm open to accepting that this might however change as more research is done on this topic.Mechanism of effect for uric acid in BD? A very good question. Unfortunately I don't have a good answer at the moment, aside from reiterating the Albert suggestion "of a purinergic dysfunction associated with BD". Going all the way back to the 1921 book by Emil Kraeplin where the connection between uric acid and "manic symptoms" was discussed, there is quite a long history attached to this area. Even further back, the paper by Sutherland (1892) [3] talked about uric acid diathesis in children exemplified by: "keen precocious minds, and small restless bodies; they are excitable, nervous, bright and amusing at one time, and greatly depressed at another". Lithium salts were the treatment of choice for the 'gouty diseases' [4] and perhaps might offer some further explanation for the mechanism of effect in BD.Other than that I can say no more, aside from pointing out that if one considers uric acid to be an agent of inflammation [5] and associated with other inflammatory responses [6], one might entertain some possible association between elevated levels of the stuff and other potentially important work in the area of BD...And to close: White Coats by Foxes.----------[1] Albert U. et al.

Gene fragments linked to brain development and autism

by Gabriel in Lunatic Laboratories

This drive had lead to a slew of causes (and risk factors) for autism in recent times.
