Push, pull and grin

After nearly a six year hiatus I hit the weights. And I found myself as my own client. "Slow, and with purpose."  "Concentrate on every millimeter of movement." "Push/pull equally; don't get sloppy."

As a personal trainer with a background in physiology and kinesiology, most of my clients were older or with 'special needs' (post-physical therapy, athletes, etc). I provided instruction, demonstration, supervision, education, and discipline. Although I was a powerlifter, I did not train my clients as one, except for one client that was also a competitive powerlifter. Each person is different and requires their own tailored program. Now I am my own client; older and with special needs.

With an accumulation of broken bones (both ankles and pelvis), permanently dislocated collar bone, herniated disks, arthritis, old sprains, and muscle loss, my younger trainer self stands in front of me reminding me how to move with purpose and concentration, with focus, and with cues. "Place finger on your left abdominal muscles to feel recruitment." ( a form of biofeedback) "Push evenly with both legs, slower on the descent, concentrate on that left quad." (Old nerve impingement) "Arms and hands level with shoulders and keep those shoulders back against that pad!" (Avoid pronation of shoulders) "Yes, ma'am'" I found myself saying. 

I can feel the stress and stimulation in my muscles and joints. 'Remember this, you tissues?' I can also feel increased circulation in my low back joints. The chronic pain has been subdued. But I know what is coming tomorrow: DOMS (delayed-onset muscle soreness). And I'll do a light whole body set, stretch to reduce the soreness (repeated bout effect). And repeat in days to come. I'm on a roll, one I should never have stopped.

It feels good to be home inside me again.

Bears in wolf clothing

Reported in May 23' 2013' issue of Nature journal:

Hot topic, scalding hot, is the observed decrease in elk population in Yellowstone Nation Park. "It's those damned wolves!!!" Wolves, the ancient scapegoat for everything. Let's look underneath the wolf clothing.

In an attempt to 'reclaim' the trout population in the park lakes, 'humans' (clarification of which humans are not mentioned in the report) restocked the lakes with lake trout. Instead of the native trout. A detail missing from the original ecological assessment was that the lake trout spawn on the bottom of the lakes, unlike the natives, which do not. The introduced non-native fish are unable to be harvested by grizzly bears. Since fish are a major dietary source for grizzlies, the bears look for alternative food sources. Elk calves.

A research team in Wyoming estimated that this dietary shift accounts for as much as 11 percent reduction in the elk population, even elk that winter outside the park. "The decline of these elk is often blamed, perhaps erroneously, on the reintroduction of wolves."

But we do so love our scapegoats, don't we?

Which came first: obese chicken or its obese microflora?

Which came first: The obese chicken or its obese microbiota? « Nothing in Biology Makes Sense!

Good summary of a recently published paper on how our gut microflora influences metabolism of the entire organism. Most people tend to think of the gut simply as a container to periodically fill and empty. Only until recent years has science demonstrated that our gut is an organ actively involved in our entire physiology, including communication with the brain and immune system. In fact, just as our body fat is an endocrine organ, the gut is also involved in our endocrine system, including inflammation.

While we consciously or subconsciously interact with thousands of environment components on a daily basis, our gut contains another environment, the microflora, which interacts in ways we are unaware of. Part of that is comprised of what we swallow, sometimes microbes that hitch a ride on food we eat or drink. But that is why we have such a complex environment inside our gut. Hordes of 'good' bacteria often battle with 'bad' bacteria, and sometimes the latter may win. We usually become aware of those battle victories. Others are minor skirmishes that go unnoticed.

It is the chronic battles that alert the big army of our defenses, the immune system. And when the balance is continually upset, the rest of the body responds and other systems may malfunction.

Although epidemiological studies have suggested that some enteric bacteria are associated with obesity and chronic inflammation, the authors of this study demonstrated that a specific bacteria strain causes obesity. (Remember that association is not proof of causation.) However, a limitation of this study is the model: gnotobiotic (aka germ-free) mice. Regardless, it is a logical progression from in vitro models to study interactions of the gut microflora and metabolism. But we have more work to do on this.

My comments submitted on the website's post:

Gnotobiotic studies have their limitations despite that they are a logical progression from in vitro studies and isolate otherwise complex immune and intestinal interactions. Gnotobiotic animals typically have immune systems and intestinal walls that are under-developed. Also, all the food must be antigen free, which is difficult to achieve. Often, secondary infections can rapidly kill off an entire gnotobiotic colony or mask effects of controlled dietary variables. In our experience with gnotobiotic pigs (which are more relevant to human nutrition and gut microflora), administered probiotics had no effect on morbidity when challenged by a single-strain pathogen, whereas pigs in conventional state (non-gnotobiotic conditions) fared significantly better. Animals in a germ-free environment do not fully represent their counterparts in a conventional environment, and variables in studies with gnotobiotic animals must be strictly controlled (and are very expensive).

I found it interesting that in neither the paper or the supplementary information was provided the specific ingredients of the ‘WTP’ diet except for the major nutrient composition. ‘Chinese medicinal medicine’? ‘Prebiotics’? As a reviewer, I would have requested this information be more specific.

Academic Assholiness

"As we talked we started to wonder: do you get further in academia if you are a jerk?"

A recent blog post, Academic assholes and the circle of niceness, on the Thesis Whisperer examines the increasing trend of academic snobbery, arrogance, and, aptly termed, 'assholiness'.

Some people ask me why I retired early from academia. Depending on the inquirer, my responses range from "It was just time to do so," to a rant on the trend of academic assholiness.

During the last nine years at a large self-inflated university that trend has increased, and, in fact, has been selected for, intentionally or not. After being recruited for a research position there, I was genuinely excited and passionate about my work. Over the next nine years of experience and observations in two departments, that dwindled to waking up every weekday morning and forcing myself to go through the motions. The last two years were simply a job while I prepared to walk away from the Academic Empire.

This is not the only university in which I have observed and experienced Academic Assholiness. Nor have I been close-mouthed about specific examples like many others that endure it and trudge on. My grievances were nodded at, checked off and ignored. I watched with anger as a research lab manager fought for her job with a lawsuit because a department head covertly attempted to have her fired. In this case, it was a prompted by an illness resulting from unhealthy environmental conditions in the department. This was an ongoing complaint by several staff and researchers over several years, but was repeatedly ignored.

Another example was a research scientist that continuously discriminated against gender and race of staff and graduate students in his laboratory. Grievances related to this individual were overtly ignored. Additionally, an academic scientist nearly destroyed the career of a young and brilliant scientist because of a personal dislike for her national affiliation and origin. And another scientist who intentionally recruited foreign graduate students to demand unreasonably long working hours, even threatening their educational and visa status if they complained. Then there's the junior scientist who feels that unrelenting humiliation of graduate and undergraduate students during their seminars or presentations elevates his own academic standing. And, lastly, the arrogant yelling at janitorial and service staff as if they were kicking a dog, or, mostly, their prevalent treatment of them as the Invisibles and Untouchables.

Finally, there is the Nobel Prize researchers recruited and installed in university departments at the expense -their research space and equipment- of other well-established and equally successful (without the NP recognition) academics, and whose snobbery and academic arrogance is overlooked and even smiled upon by university administration.

These are members of the increasing species of Academia assholiata that I see rapidly evolving in our social environment. I could continue with examples from 28 years in academic halls and three universities. Only one of these institutions, a small university, had a credible and effective process for grievances. The other two institutions had sham committees. Speaking openly meant being blacklisted. In the past four years I have seen too many young and bright scientists leave academia, and am now seeing a flood of older scientists flee, some jaded and bitter.I left last year without looking back.

I am heartened and pleased to see more public discourse like this post on these issues, and I encourage others in all levels of academia to be more outspoken.
