A Universal, One-Shot Flu Vaccine?

ResearchBlogging.orgA Better Grip: T Cells Strengthen Our Hand against Influenza Clinical Infectious Diseases, 52 (1), 8-9 DOI: 10.1093/cid/ciq018Flu vaccines are important and useful, but also relatively ineffective compared to many other vaccines. Immunity is imperfect, there are many ‘strains’ of influenza in a given year only some of which are addressed by the available vaccine (though often the most common ones) and one year’s vaccine does not provide immunity to subsequent years’ influenza because the virus changes so much. Well, actually that’s not exactly true: The influenza virus has various different parts, and the parts that the traditional flu vaccine uses to induce an antigenic reaction in the potential hose is highly variable. Other parts of the flu virus are not as variable. If only a vaccine could be developed that uses the less variable part of the influenza virus, then perhaps it would be a universal, long-lasting vaccine that you take once, and become pretty much immune to all future influenza.

Milk allergy is the most common form of food allergy found in humans, but you don’t have one and neither does your baby

Well, maybe, but probably not. Even though milk allergies in infants and very young toddlers are the most common food allergy, they still occur in only about 2.5 percent of the population in the US and other Western groups. For this reason, I was rather perplexed some months back when I encountered a group of eight mothers randomly assembled, three of whom had infants with milk allergies. Two of the mothers had started to eliminate all dairy from their diets, including eggs, in order to reduce the effects of the milk allergy on their infants. Who were breastfeeding.

The Genetics of Pesticide Resistant Bedbugs

ResearchBlogging.orgBedbugs (Insects of the Cimicidae family, commonly Cimex lectularius) are annoying, might carry diseases (though this is unclear, so probably nothing importat1, and are apparently becoming more common in the US. Interestingly, there has been very little study done of their genetics. A new study just out in PLoS ONE looks at the bedbug genome in an effort to better understand pesticide resistance in these pesky critters.

Vaccination vs. Disease: Which is worse?

It is very reasonable for a parent to worry about vaccines. For one thing, most of them involve sticking the baby or child with a sharp object, thus making the little one cry, and it would be abnormal to not have an automatic reaction to that. For another thing, they are drugs, in a sense. When the little one is ill, and you call in to the health care facility in the hopes that there will be some useful advice, most of the time you hear “No, we no longer recommend giving [fill in the blank with a medicine you thought might work] to children under [one or two months older than your child]. But if [symptom] persists for more than [amount of time that is 12 hours longer than the symptoms ever persist], call back.”

Don’t forget to get your flu shot

According to the FluView report for the week ending January 1, influenza activity has picked up over the last few weeks in the United States. This increase in activity is typical of the start of flu season. The number of states reporting regional or widespread influenza activity increased. Although influenza activity can rise and fall during an influenza season, activity in the United States generally peaks in January or later in most years.

CDC

Of concern: Britain is experiencing a bit of a spike in flu cases and flu deaths, and it is thought that the “swine flu” H1N1 version that emerged last season is responsible for that. There is concern that this will spread across the European continent. I have no idea what this may mean for the US, Asia or elsewhere.

How to make homeopathy work

Homeopathy involves the acquisition of a substance often chosen because of its harmful nature (but sometimes for other reasons) followed by the dilution of that substance, or an extract of it, in water numerous times until the substance itself is essentially gone, but the memory of the substance is retained by the water. This water, with the memory, is then considered by homeopathic practitioners to be an effective treatment for various conditions.

The basic principle of using a harmful substance to produce a sort of counter-reaction, or a beneficial reaction, is interesting. And, the idea of using some sort of organic memory is also interesting and potentially quite effective, if it can be pulled off. Most of my colleagues in science-based skepticism dismiss homeopathy as inconsequential and ineffective, in part because there are no double blind controlled studies with usable sample sizes, properly selected samples, appropriate statistics and biologically sensible analyses demonstrating effectiveness, and because there is no evidence of water having “memory” or of a substance diluted into non existence having an effect. But I think they may have given up too easily on this idea, and there is a way to make homeopathy work. We just have to change a couple of the parameters.

First, the substance that is used in dilute form needs to be a biologically potent substance, and not just some thing someone thought might work. For instance, if you take silica based crystals such as quartz and grind them up into a powder and ingest the powder in small quantity, there will be either minimal effect or a small effect similar to consuming a dose of fiber supplement. I don’t recommend trying this, because if the crystal contained certain minerals then the substance could be quite poisonous, and even if the powder is 99.9999999 percent silica, silica powder can be harmful (if inhaled). However, from the point of view of how natural systems work, crystal per se should have little effects by itself, especaily if ground up.

On the other hand, organic substances, those that are made up of cells or parts of cells, can have very powerful natural effects. This is because the body contains natural molecules that interact not only with each other, but also with natural molecules of organic origin that are introduced into the body. And, most interesting, it has been demonstrated in many studies that these reactions can literally change, in a natural and organic way, the body’s natural molecules. Furthermore, and this may seem hard to believe but it is really quite wonderful and proved in many studies, but the molecules in the body that are changed can “learn” to assist cells in making more molecules that, in turn, are changed in the same way. I’m oversimplifying a bit, but I think you may have already guessed where I’m going with this: The introduction of certain organic natural materials into the body can result in the body developing a long term memory of those molecules. Studies have shown that this memory, in many cases, lasts a lifetime, or at least, for several decades.

So, we have all the homeopathic elements: Substances that can be very potent, processed so they are in small concentration, introduced into the body, causing a memory reaction not in the water the substance was originally mixed in, but IN THE BODY ITSELF using purely natural and organic bodily processes. This memory will last a life time, or nearly so. In this way, a properly selected natural organic substance can cause a highly desirable re-conformation, in a totally natural and organic way, of the body’s reaction to stresses that originate from the outside.

How social networks predict epidemics

You will recall my post: A genetic cause of rapid degeneration in some Alzheimer’s patients. Well, now it (the topic) is a Ted Video. But before you watch it, I need to take down Nicholas Christakis for saying the dumbest thing I’ve heard all week.

No, Nicholas, it is not true in any way whatsoever that humans did not have complex social networks prior to “emerging” from the “African Savanna” … nor would the implication that you make that those still living in Africa, or the savanna therein, fail in this way. That’s just you being an ignorant racist westerner. Otherwise your talk is moderately interesting, and since it relates to the above linked post, I’ll be happy to put it on my blog.*

*Note: The casual and probably unintentionally offensive remark implying that humans really didn’t become human until leaving the Dark Continent could have been left unused. It added nothing to the talk. But it was an example of casual racism which, like casual sexism, is bad but unlearnable.

A genetic cause of rapid degeneration in some Alzheimer’s patients

ResearchBlogging.orgA new study identifies a likely cause of rapid degeneration in some Alzheimer’s patients. The results of this study may lead to improved treatment.

But first, let’s look at the method used in this study, because that may be almost as important as a development. And for this, we will use a sports analogy.

Science proves that your friends are more important than you!

Editor’s Selection IconThis post was chosen as an Editor's Selection for ResearchBlogging.orgThe other day a friend of mine bumped into some news that concerned her. She could have asked a random person about this to find out more information, but there was a bit of information that came with the news indicating that I might know more than the average person about it. So, she asked me, and as it turns out, I did not know anything. But, having heard the news from her, I noticed a different bit of information that came along with it that told me exactly who would know everything about it, so I sent along a question …. “What’s going on with the [deleted]?” I got back a message almost immediately.
