This document provides a summary of a lecture on the human microbiome given by Dr. Larry Smarr. Some key points:
- The human microbiome refers to the trillions of bacteria that live within the human body. Each person contains 100 trillion bacteria, outnumbering human cells.
- Research into the microbiome is a rapidly growing field that provides insights into health and disease. The microbiome plays a role in processes like drug metabolism and immunity.
- The microbiome is established early in life and influenced by factors like birth method and antibiotic use in the first years. This early development can impact future health.
- Microbiome imbalances are linked to diseases like inflammatory bowel disease. New treatments are

Attendees (and their microbes) at this event enjoyed a lively discussion on how we might better interact with our environment to support a healthier life for ourselves and our children. Think with your microbes about why we have to suffer from ever-increasing numbers of debilitating chronic diseases (asthma, food allergies, diabetes, autoimmune conditions, obesity, heart disease and cancer).
with Dr. Rodney Dietert, Cornell University Professor, Department of Microbiology and Immunology
Dr. Rodney Dietert is an internationally-known author, lecturer, scientist, book series editor, and educator. He is the author of Strategies for Protecting Your Child’s Immune System, and Science Sifting: Tools for Innovation in Science and Technology.
The concept of the human microbiome was first suggested by Joshua Lederberg, who coined the term ‘‘microbiome, to signify the ecological community of commensal, symbiotic, and pathogenic microorganisms that literally share our body space’’
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

As Your Human DNA-Bearing Cells
Your Body Has 10 Times
As Many Microbe Cells As DNA-Bearing
Human Cells
Inclusion of the “Dark Matter” of the Body
Will Radically Alter Medicine
4. New Estimates In 2016 Estimate a Human Body Contains
~30 Trillion Human Cells and ~40 Trillion Microbes
However, Red Blood Cells and Platelets Have No Nuclear DNA.
Therefore, Ratio of DNA-Bearing Cells for Human vs. Microbiome is Still >10:1

14. The Human Gut Microbiome and Pharmacy
The gut microbiota have been shown to have an important influence,
direct and indirect, on the metabolism and toxicity of a wide range of drugs
and xenobiotics. The major drug-metabolizing capability of the gut microbiota
is reductive metabolism, but demethylation, dehydroxylation, deacylation,
decarboxylation, and hydrolysis reactions have also been demonstrated as well
as acetylation. Microbiome-driven drug metabolism can result positively
in the activation of prodrugs to their pharmacologically active forms
or alternatively result in adverse consequences such as toxicity.
In addition, the gut microbiota can affect drug metabolism and toxicity indirectly
via, e.g., competition of bacterial-derived metabolites for xenobiotic
metabolism pathways or the modulation of host metabolic systems.

33. From War to Gardening:
New Therapeutical Tools for Managing the Microbiome
“I would like to lose the language of warfare,”
said Julie Segre, a senior investigator at
the National Human Genome Research Institute.
”It does a disservice to all the bacteria
that have co-evolved with us
and are maintaining the health of our bodies.”
