Much has been written here about the dietary supplement business, a multibillion dollar industry with powerful political connections, and about the woeful inadequacy of regulation which allows widespread marketing of supplements without a solid basis in science or scientific evidence. The veterinary supplement market is a pittance compared to the human market, but still a billion-dollar pittance that is growing rapidly. Unfortunately, the resources available for good quality research in veterinary healthcare are also a pittance, and it is not at all unusual for our pets to suffer, or even be euthanized, as a result of treatable diseases for want of money to pay for needed care. So $1 billion a year spent on nutritional supplements may not be such a good deal if ...

Unsettling enzymes – Millisecond oscillations can massively impact how an enzyme functions, a new NMR spectroscopic study in the US reveals. The study suggests that finding ways to control such movements, without altering the overall structure of an enzyme might be useful in disabling an enzyme in disease. Proof of principle was demonstrated with an enzyme from Escherichia coli.

Neutrophils: Last Thursday, April Fools Day, the Mayo Clinic lab reported my neutrophils at 940/uL, well below 1700, the bottom of the reference range, and even below the cutoff of 1000, where the pomalidomide trial protocal calls for a reduction in my dosage of pomalidomide. So we re-tested today, at Stillwater Medical Group, and got a count of 1500/uL. That's good - Mayo already called and told me I could stay on the protocol. But I'm quite surprised that the neutrophil count can jump up that much in just four days. I heard that the count can be improved by exercising before the blood draw, so I did some pushups, a few flights of stairs, and some runner's stretches before heading off to the clinic. But even if t...

The study on which that claim is based was widely and often quite misleadingly trumpeted across the Internet yesterday (July 6, 2009). Although some responsible sites included in the headline that the tests were done in mice, many concealed this important fact until you were well into the article and had already been exposed to whatever advertising was on the page. I’d already seen several misleading headlines before I realized the studies were in mice and I’m sure that many people didn’t ever get the full story. The entire webisode was set in motion by the University of South Florida Health’s press release, a slick piece of PR entitled &#...

This fungus was chosen for sequencing because it was found on canvas tents eating the cotton material suggesting it may be a good candidate for degrading cellulose plant material as part of cellulosic ethanol or other biofuels production.  The fungus also has starring roles in industrial processes like making stonewashed jeans due to its prodigious cellulase production. The most surprising findings from the paper include the fact that there are so few members of some of the enzyme families even though this fungus is able to generate enzymes with so much cellulase activity. The authors found that there is not a significantly larger numb...

Previous work (nicely reviewed in the fungi by Nancy Keller and colleagues) has shown the the PKS genes have several domains. These domains include acyl carrier protein (ACP), transacylase (SAT), ketosynthase (KS), malonyl-CoA:ACP transacylase (MAT), “product template” PT, Aand thioesterase/Claisen cyclase (TE/CLC).  These domains make up PksA, but the specific role of each domain's in synthesis steps has not been fully worked out. Understanding this process and the specificity of the chemical structures that are created can help in redesign of these enzymes for synthesis of new molecules and drugs. The...

Being in its early stages, it is none the less exciting in that it could provide new treatments… As a possible treatment for such conditions as congestive heart failure, this technique could present an alternative to current therapies that counteract heart muscle weakness by boosting cellular calcium content, Shroff said. The heightened calcium improves muscle contraction but also results in more energy consumption in hearts that often are energy-starved to begin with. This could prove to be a much safer way to treat these patients. Next is looking at the contraction ov...

Contest time at The Bolt! The very first one since Liz and I took over. Don’tcha feel like crying with excitement? Um, okay. Maybe that’s just me. Anyhoo, here’s the scoop: We’re giving away a spiffy hardcover copy of the newly-released Everything You Need to Know About Enzymes, by Tom Bohager. Whether you’re hip to the benefits of enzymes or not, this book will clue you in. Written in a very friendly and relatable style, Mr. Bohager addresses the world of enzymes and their presence in our food sources and dietary supplements. Their primary role, Bohager suggests, is to relieve the digestive system of otherwise tedious activity, freeing up energy for our body to address the rest of its needs. The book is written with digestible (yep, pun intended) conve...

FOLy: an integrated database for the classification and functional annotation of fungal oxidoreductases potentially involved in the degradation of lignin and related aromatic compounds - so a database of these enzymes from several different fungi including some of the white rot fungi. I'll be curious to see how the brown rot fungus Postia's genome complement compares. Evolution of host resistance in a toxin-producing bacterial–fungal alliance. Some more fungal-bacterial symbosis work in Rhizopus that follows on previous work that shows that the bacterial make a toxin that is anti-mitotic, so how does this not affect the host fungus?

That’s me. I cannot start the day without coffee and I cannot go on with my day without having more coffee somewhere in between. I need the perk that the caffeine in coffee provides. I cannot remember exactly when I started drinking coffee. But I guess it must be early in my teens, because I am one of those that gave up drinking milk early. Anyway, I can live with the perk the whole day, but at night time I need something to calm me down. I dare not drink coffee beyond 5 pm, otherwise, I will be awake the whole night. So, to calm me down, I usually drink (cups of) tea after dinner. Tea has that soothing effect for me, especially green tea. We have read and heard so many health benefits from green tea already. It’s anti-heart disease benefits and most importantly, green t...

Tau is involved in Alzheimer’s and other neurodegenerative diseases, but scientists don’t yet understand its role. In the long run, understanding how tau contributes to brain cell death may help researchers develop new Alzheimer’s treatments. More than a year after Dad died, I’m still trying to understand what caused his dementia and death. His primary diagnosis was cerebral amyloid angiopathy, but “it is likely that the presence of plaques and tangles contributed to his neurologic difficulties,” his autopsy consultation report says. These plaques and tangles are signs of Alzheimer’s disease. A lot of Alzheimer’s research focuses on plaques and on beta amyloid, the protein that makes up...
