Think about it…
The Thinker

* Why is it when a door is open, it’s ajar, but when a jar is open, it’s not a door?

* Tell a man that there are 400 billion stars, and he’ll believe you. Tell him a bench has wet paint, and he has to touch it.

* How come Superman could stop bullets with his chest but always ducked when someone threw a chair at him?

* If “con” is the opposite of “pro,” then what is the opposite of progress?

* Why is it lemon juice contains mostly artificial ingredients but dish-washing liquid contains real lemons?

Wisdom to Ponder…

Bob Hope
1903 ~ 2003
His career as a comedian and actor spanned almost 80 years. He was best known for his 41 tours entertaining US troops with the USO.
“I have seen what a laugh can do. It can transform almost unbearable tears into something bearable, even hopeful.”

“I grew up with six brothers. That’s how I learned to dance – waiting for the bathroom.”

“People who throw kisses are hopelessly lazy.”

“She said she was approaching forty, and I couldn’t help wondering from what direction.”
“You know you’re getting old when the candles cost more than the cake.”

“Middle age is when your age starts to show around your middle.”

“You never get tired, unless you stop and take time for it.”

“I do benefits for all religions – I’d hate to blow the hereafter on a technicality.”

“When we recall the past, we usually find that it is the simplest things – not the great occasions – that in retrospect give off the greatest glow of happiness.”

Optical oddities… 

Which of these three diagrams is different?

Sure hope you said the middle one, 

because that is the one that is different

from the other two!



Adaptations increase pathogenicity…
Bartonella is a bacterial genus capable of causing several human diseases. The three most common are cat scratch disease, caused by B. henselae; trench fever, caused by B. quintana; and Carrión’s disease, caused by B. bacilliformis

Cat scratch disease can be transmitted from the scratches of cats, particularly kittens, due to cats harboring infected fleas that carry Bartonella. Most cats carry the bacteria in their blood without getting sick and some studies have found that 1 out of 3 healthy cats carry Bartonella in their blood. 

Trench fever is transmitted by the human body louse and is most commonly associated with homeless populations or areas of high population density and poor sanitation. In a recent analysis, it was found that about 33% of body lice recovered from infested homeless people were PCR positive for B. quintana

Carrión’s disease is transmitted by bites from sand flies that carry the organism. These infections are endemic in the Andes Mountains in western South America, including Peru, Colombia, and Ecuador. 

Although different Bartonella species have different vectors of transmission and cause different types of infections, what they all have in common is the ability of the Bartonella bacteria to adapt to vastly different host environments. How are these bacteria overcoming stressful changes in their environment, and can the answers to this question lead to development of specific treatment for Bartonella infections?

Dr. Jane Koehler at UC San Francisco has studied the transmission of Bartonella quintana and has found temperature-specific regulation of genes that may confer survival of the organism in its two different hosts, humans and body lice. B. quintana must undergo change in temperature between hosts and a drastic change in hemin concentration between hosts. The louse vector has an internal body temperature of 28°C and very high hemin concentrations in the gut. In contrast, human host temperature is 37°C and the human bloodstream is hemin-restricted. Although hemin is necessary for Bartonella to obtain an iron source, the levels of hemin contained in the louse gut are at toxic levels, producing reactive oxygen molecules that can be lethal to bacteria. B. quintana must contain mechanisms that allow it to survive when exposed to decreased temperatures and increased hemin concentrations in the body louse gut.

Bartonella produces a family of hemin binding proteins (Hbp) that are responsive to temperature, hemin concentration, and oxidative stress. They also produce hemin utilization (Hut) proteins that are involved in hemin sensing, degradation, and storage. Both Hbp and Hut proteins are most likely important players in Bartonella’s ability to survive in a wide range of hemin concentrations.

Wild type B. quintana has greater tolerance of high levels of hemin than what was observed previously for B. henselae. The difference in hemin tolerance displays how evolutionary adaptation allows each Bartonella species to adapt to its specific arthropod vector. Understanding what is essential for Bartonella survival and targeting the vector stage is important for interruption of the body louse to human transmission cycle.

The Antibiotic Apocalypse Explained…
Drug Resistance


We have come across a beautifully animated video from Patreon that explains drug resistance in a simple but elegant way. View the video now.

Discussed in the video is how antibiotic resistance oftentimes originates in farm animals. Did you know that 80% of all the antibiotics in America are used for meat-producing animals? Is it any wonder how we got into the resistance mess that we are in today?

Guess Who?
Below is a Vision and Value statement from 
a famous company. Can you guess who?

We treat others as we would like to be treated ourselves. We do not tolerate abusive or disrespectful treatment. Ruthlessness, callousness, and arrogance don’t belong here. 


We work with customers and prospects openly, honestly, and sincerely. When we say we will do something, we will do it; when we say we cannot or will not do something, then we won’t do it. 


We have an obligation to communicate. Here, we take the time to talk with one another…and to listen. We believe that information is meant to move and that information moves people. 


We are satisfied with nothing less than the very best in everything we do. We will continue to raise the bar for everyone. The great fun here will be for all of us to discover just how good we can really be.

I was struggling to figure out how lightning works; then it struck me.

I don’t mind kids playing hopscotch in most places, but my driveway is where I draw the line.

Time flies like an arrow. Fruit flies like a banana.

I try wearing tight jeans, but I can never pull it off.

I heard the new auto body shop that opened comes highly wreck-a-mended.

Did you hear about the celery that was arrested? It was a stalker.


Do you do Growth Promotion Studies?

Guess Who?

If you guessed Enron, you would be right. Enron, which went bankrupt in 2001, remains as the best example of systematic, premeditated, pervasive, and planned corporate fraud and stock price manipulation. Most of its 20,000 employees lost their jobs and their life savings due to the unscrupulous activities of Enron’s leaders.
