bugs, seashells, skulls

This semester the majority of the students use a variety of Micro-pens. Note the line work in this assignment, some indicates structure while some indicates texture.

The subject matter is a natural and complex form. Students used to draw only shells. A few years ago I brought in bugs. This semester, thanks to the PC biology department, we have small animal skulls. The composition is to include 2-3 objects and students must balance out positive space with negative space.

While I would like each student to include 1 of each (bug, shell and skull) in their composition, I let them pick and choose. I’m not surprised some students don’t like the bugs. I’m very surprised others don’t care for the skulls. And I understand why most of them love the variety in the seashells.

Santan focuses on a star fish.

Drawing students learn the skill of observation. Using a magnifying lens, they look closely at the form and surface of their complex object. Marker (no eraser) forces them to work slow and careful. They learn to focus. They learn patience, commitment and discipline. During critique we talk about how these traits show up in the work.

The assignment goes well. Here are a few of the studies.

Early in the semester, students tell me about Inktober. In general, I think the idea behind this is one ink drawing a day throughout the month of October. This study takes at least 4 days for the majority of the class. But it’s still a fine drawing for the month!  #inktober2019


The post includes only a few of the drawings. You can see all of the work on Thursday, November 7th, when Phoenix College (main campus) celebrates National STEAM (Science, Technology, Engineering, Arts, Math) day.  Free and open to the public. You’re invited!

pretty close to a PSA …

2 things….
Last week I had a very quick (and very spontaneous) introduction to molecules. (Thanks Joseph!)  I returned to the studio loving the ball-and-stick sculpture-like forms, knowing  they’d show up in the current study (Portrait of Veronica).

and…
This week gut microbes ↓ enter the picture plane. And maybe…so does microbial imbalance aka dysbiosis.

Portrait of Veronica (lower edge of the life-size study)

Understanding Omeprazole is an antacid, I was never at ease hearing Veronica would be on it for the rest of her life.

Omeprazole is what is known as a Proton Pump Inhibitor. PPI’s are among the most widely used (prescription and over-the-counter) medications. They are linked with obesity (among other things). And long term use can be harmful.

I always planned to include something in the composition about antacids. I just had to find the right way to do it.

Enter: Molecules! ↓ Here is omeprazole. I like detailing the form and purposely choose sweet colors  (like candy which many antacids tend to resemble).

FYI, my source for information on antacids is Joe Alcock. If he’s involved, always know the microbiome is involved. He refers to gastric acid juice as the gatekeeper to the microbiome.

Consider stomach acid kills microbes that enter the gut along with food. When gastric acid output is blocked, say…by an antacid, understand the stability (balance) of microbiota is also altered. It appears good bacteria might be reduced while harmful (and opportunistic) bacteria remains.  (Gastric acid also supports absorption of calcium and B12.)

It’s complicated…
#SmallIntestinalBacterialOvergrowth #Dysbiosis #Inflammation #WeightGain

I take a minute to email Joe, who notes there are a few conditions for which life long omeprazole makes sense. For everyone else, he says, PPIs should be a very short term drug.  Read his post and find out why → Killer antacids

You’ll be seeing more molecules in my study…

histology of the gut, horror vacui at its finest

Rafting the Colorado River a couple of years back, I remember looking at the surrounding walls of the magnificent Grand Canyon. Moving deeper into it, all the while wondering to which organ in the body could I compare the environment. You know … if one day I was to draw on the experience.

Interestingly, more than half the people on the trip were medical professionals. Daily conversation allowed for a variety of responses… lymphatic system, kidneys, adrenals…etc.

I was thinking intestine, more specifically large intestine. If I was there today it could be the entire digestive system.


The last few weeks, I’ve put the portrait of Veronica aside to work a painting for an invitational exhibition. The small study helps me to work out an area of the larger portrait drawing where I struggle.

Collaging a map (of the Grand Canyon) onto canvas, I think about the topography of the GI tract. And looking at histology of the gut, I think horror vacui at its finest!

These multi-colored and multi-finger like ↑ forms are my version of enterocytes.
What: Enterocyte (a cell)
How and Where:  Line up and form intestinal epithelium, (inner surface of the intestine).
Think barrier, absorbing beneficial stuff (like sodium, calcium, magnesium, zinc…B12…water…etc…so much more than this but I want record of a few things).
And they restrict entry of harmful stuff (like microbes/pathogens and toxins).
They have an endocrine role (secrete hormones).

Can you tell my interpretation ↑ of this structure of tissues, in the abdominal cavity, hints at gut inflammation? Note the abdominal fat (visceral fat at top and bottom edge) also forms a barrier (surrounds and seals).
What: Adipose tissue (Visceral fat/VAT)
Where: Within abdominal cavity
Why: Fat protects organs by trapping and killing escaping bacteria.
Endocrine organ secretes protein hormones.

Casein, egg tempera, collage on canvas, 19.5 x 26.5″ (WIP)

The composition includes enterocytes, adipocytes, t-cells, macrophages bacteria, viruses…and other stuff…

Painting with casein and egg tempera, I can’t help but think about the food we eat. Casein and egg yolk are binders (adhesives), mixed with pigment, they are my medium. Milk and egg, do they stick…to the gut too?

#wip #horro vacui


Earlier in the month, working the portrait of Veronica with its focus on the microbiome and obesity, I wanted to set the lining of the intestines into the composition ↓. I have to be honest; I kept losing my sense of the space. I needed a map of some sort. I also needed to understand some things → Fat fights back.

So physical…this stuff… and wonderful. It seems to me… the body…might be trying to protect itself (you and me). #sosubtle

food. who’s in control?

The question: Can gut microbes influence our eating behavior?

Veronica sends a short list of the food and drink she particularly enjoys (and on occasion craves).  Meanwhile I figure out the composition.  I weigh choice and consequence.

Microbiome. Healthy food / Unhealthy food. I weigh the food that feeds good microbes and promotes health (plant-based, fiber-rich) against the food that feeds bad microbes and supports dysbiosis (microbial imbalances that drive disease).

A few things I learn along the way: Less diversity of the microbes in our gut can lead a person to obesity. A healthy microbiome can protect us from infection and disease and produces vitamins (B12 and K).

I know (cuz I draw) there is limited space in the gut. I also know microbes complete for the space. Microbes use it = Microbes use us.  Microbes compete with each other and they compete with us (their host) for space and resources.

What if each and every individual’s gut microbes have needs and wants of their own ? This sort of changes the picture, doesn’t it? And you thought self-control (or lack of) was the main thing driving your food choice and intake.

This whole thing starts to make a little more sense as I draw and paint the food on Veronica’s list, into the composition. I can’t help but think about all the apartments going up in Phoenix and all the growing city traffic. Microbes, like Phoenicians, might be trying to figure out how to survive and thrive in dense environment. #competition

Below are some of the images and notes I post into social media. And as usual…the food pulls in the people (comment threads, not included, were interesting to read).

Pepsi 🥤 has 41g of sugar (and 38mg of caffeine). A Snickers bar 🍫 has 27g of sugar and 14g of fat. Who do you think craves sugars and fats more? You or the microbes  that live in ur gut? #Conflict between #host (you and me) and #microbe (our bugs!). #obesity

I read somewhere that the grilled cheese🧀 🥪  might be the most popular sandwich in the world. 😮 Could this be true!? You tell me. They always remind me of my grandmother who used to take me to a local diner to enjoy one. She loved ❤️ a good grilled cheese 🧀 🥪 . All I’m going to say is that they change your gut flora. All dairy changes the gut flora. It has something to do w short chain fatty acids (lipids). Do your microbes 🦠 love 🧀 🥪?? I bet some of them do. #oozycheese btw…all food changes the gut flora. #bread and #butter #noprocessedcheese

I wrote about the benefits of 🥑 in my last study and they’re plenty. In this current study about obesity and microbes 🦠 – things get complicated. 🥑 are unsaturated fats (monounsaturated and polyunsaturated). It feels to me like the benefit might be unique to each individual depending on their gut microbes. 🥑 satiate and if everything is balanced they can suppress hunger and increase meal satisfaction. But if it’s true that microbes 🦠 can hijack our neuronal systems 😮 and our 🧠 brain (I 👂 they can!) well then this changes things. Do microbes 🦠 compete w us for food and energy? It’s the question here. Anyway- I ❤️ 🥑. #appetitehormones #WhoIsInCharge? Is there anyone who doesn’t love a good guacamole?!

🥩 The art of the red meat 🥩 (in this case medium rare). What if 🥩 red meant promoted the growth of bad 🦠 bacteria? And what if we benefitted from eating less of it? This is how I 👁 it (as I ✏️ it). Think about the space in your gut 🤔. It’s limited, right? And tunneled and narrow and twisty turny… Why would we put something hard to digest into our gut to take up space (for a good amount of time) when we can eat more fiber-rich and plant-based 🌱 food that promoted microbes beneficial to our gut? Things could move easily, quickly, take the turns smoothly…or not. Just something light and easy to think about. 🤔 WhatKind? HowMuch? HowOften?

Clementines. 🍊 Oranges! Fruits feed good bacteria 🦠 . 🍊 🍊🍊 in particular have some sort of soluble fiber our gut bacteria 🦠 ferments. One of the byproducts of this process is a fatty acid called #butyrate. Butyrate helps maintain the cells that line our GI tract. And that’s a good thing! You know the soluble fiber is mostly in the stuff that divides the segments of the orange…so eat them all up. Good stuff! #ShortChainFattyAcid #VitaminC #AnOrangeTreeGrowsInPhoenix 🍊🦠

The last thing I draw on the list is 🍺. Veronica likes a German wheat beer called Hefeweizen. I played w the logo Hefe and turned it into the word Jefa. #Jefa, Spanish slang indicating the female #boss.  She is! Ok, now back to the microbes…🤔 Who craves the 🍺? You? or your microbes 🦠? Which microbes? #VitamiminB #Polyphenols Your body lets you know. #OrDysbiosis

Do microbes influence your eating behavior?

no woman is an island

I receive a card a few weeks ago from Margaret:
Thank you for my new milagro. I plan on sharing it with my sisters Elizabeth and Kathryn. It will travel between my home in West Virginia and their homes in New York. My sister Kathryn and I make these needle felted things we call talismans, small, discrete lovely things about the size of your milagros. It will hang with these among other things at my altar for my mother, Elena, and her spirit will continue on vibrant as ever, only from a different plane.

Continue your work, it serves the world and graces what we think of ourselves. 

This note – so thoughtful.  And reading the last sentence a few times, I can’t help but wish for every woman, every mother, sister and daughter, to hear, to know words like this too.

Margaret writes in January of 2019:
I didn’t know what to picture when I learned my mom had colon cancer. Scans don’t show anything. Doctors draw diagrams and talk in the abstract. One doctor showed me his pinky and said my mother’s colon was like the diameter of a pencil. I said ok but what does that mean? I forgot to say what does it look like? Soon the vision wasn’t pretty in my head. But your artworks helped me see something beautiful and lively, chromatic. Epic and often exuberant, full of lines overlapping with pattern and movement. The organs in my mother’s body that were filling with cancer look different to me because of your artwork. I saw energy, I saw her perseverance, vivaciousness.

I can’t remember if I ever told her about your artwork. I think I was afraid to be implying she should love her cancer or love her colon, liver, lungs and linings which is where it all went. Instead I loved her as much as I could and I loved your drawings privately for myself in a way to make peace with the situation. Thank you for that. I wish you a happy new year. Thank you for doing what the doctors couldn’t do. You gave me a beautiful visual through which I upheld my mom the best I could.

I’ve had interaction with Margaret about her relationship with her mother and how my work affects her, since 2016. In that time I’ve sent along images (a couple below) as she requested. And I aways sent my best wishes for her and her mother.

I tell Margaret my interest is in both the physical body and in the subtle body. I feel she responds to both but most especially she picks up on the subtle (the unconfined and the constant). Margaret will always share connection with her mother. I appreciate knowing my drawings remind her of this.

Contacting me this summer, she looks for a work, something small, intimate and feminine in quality. I love the request and pull a few small, 2-sided, translucent studies. I call these pieces milagros, Spanish for miracle. The votive offering itself is connected to altars and/or shrines. I also call these small artworks holders of light because they do hang in space,  taking in and reflecting out on both sides. I photograph and send her a number of them, including the breast/mammary gland, which is the one she chooses.

Thank you Margaret for sharing the beautiful spirit of your mother with me. I wish you and your sister the very best. #Motherline #HolderOfLight

gut. brain.

What do you visualize when you read the phrase Gut-Brain Axis? Or Brain-Gut Connection?

I picture very active brains communicating with very active intestines. Or is it the other way around? Both. It’s a two-way, busy connect especially when you consider the wandering nerve, aka, the vagus nerve. Think: 2-way, information highway. The vagus nerves are paired cranial nerves (CN X) and happen to be my favorite of all the nerves.  Because it is the longest nerve in the body it moves alongside heart and lungs and goes through all the organs of the digestive tract, connecting brain to gut.

I enjoy the challenge of capturing Veronica’s likeness while I work her profile.  I organize and sketch in the brain. The small area of my drawing is detailed into a collaged map of El Paso,TX,  where my cousin lives.

I have fun with the photo ↑ and strategically place color pencils to direct attention to the brainstem, the area of the brain I am working to understand.  I imagine the space to be like a facility loaded with chemicals and chemical messengers / hormones and neurotransmitters. Think: Food intake. Signals and controls. Many and complex. (FYI – purple pencil points to vagus nerve start.)

Some of the hormones involved include adipoectin (a protein hormone that modulates glucose regulation and fatty acid oxidation), and leptin (made by fat cells and decreases appetite).

Veronica, during our initial conversation, noted ghrelin. Ghrelin is a hormone that stimulates appetite. If I understand correctly, it is primarily released in the stomach and signals hunger to the brain. It also plays a role in determining how quickly hunger returns after a meal. And it promotes fat storage. After my surgery, she says, no more ghrelin. No more! What does this mean?  Forever? I ask.  I don’t know, she answers. And now you eat because??
I must live!
Ah…survival!

Side note: The hormones that play a role in obesity, do they also play a role in anorexia?

I haven’t brought the microbiome in yet. But I will. Now when I hear gut-brain, I also think of microbes.  FYI…they can influence hunger and satiety.

Anyway…I’m still laying ground work…which is both complicated to figure out and complicated to draw. Both my brain and my hands are keeping busy.

One more thing…
In early posts I highlight the brown adipose tissue (BAT) and the white adipose tissue (WAT). Now I study and set in subcutaneous adipose tissue (SAT) located under the skin and visceral adipose tissue (VAT).

In the image above, ↑ I enhance (darker area) the greater omentum (cool name! for an organ) , an example of VAT. It looks like lace, doesn’t it?  This apron of fatty tissue, connective tissue and lymphatics,  comes down from the stomach and stretches over the intestines. The greater omentum, aka, Policeman of the abdomen, might just be the first line of defense against toxins or infections (microbes).

BTW…yes, there is also a lesser omentum…

Meanwhile… drawing circles/making connections.


Keeping a note:
Amylin is a hormone, co-stored and co-secreted with insulin in response to nutrients. It promotes satiety by mediating brain function, including appetite inhibition.

Amylin also plays a role in neural regeneration. It helps regulate glucose metabolism and modulates inflammation. I pull it aside and note it here because of a possible link to Alzheimer’s Disease (Type II Diabetes).

macrophage – large. eating. cell.

Laying out and studying a white blood cell called a macrophage (Greek makrós – large, phagein – to eat).

macrophage

Big eater, what’s your specialty?

Macrophage, your lot belongs to the immune system. You are King of the Phagocytes. Phagocytes are cells that protect the body by absorbing/eliminating harmful particles, bacteria and dead or dying cells. M1 macrophages attack invaders (microbes) by creating an area of inflammation around them. Perhaps you keep pathogens from spreading? M2 macrophages decrease inflammation and encourage tissue repair.

Side note…
Based on this, can I make 2 simple assumptions? Can I deduce chronic inflammation signifies organ or tissue has been invaded by a pathogen or there is injury?

Macrophage, you can take up residence in specific organs. For example, they call you Microglia in the CNS,  you are a Kupffer cell in the liver, and Adipose tissue macrophage in Adipose tissue. And other macrophages, like scavengers, you wander the body cleaning it up.

You remove dying or dead cells and cellular debris by engulfing pathogens and digest/destroying them. Sometimes a pathogen sabotages your process and decides to live inside of you. In the case of the latter, the immune system doesn’t have a clue (or does it?) as the invader begins to replicate itself.

macrophage with bacteria and debris

I know you a little better because I’ve drawn you. You are as intimidating as you are beautiful.


Postscript:
Right now I am looking at the relationship between gut bacteria ( the microbiome) and adipose tissue. Here now enters the immune system. The reason I took the time to draw out and investigate the macrophage (I don’t pretend to understand.) is because I made a connection to the microglia in the brain.
I was studying the brain (My father lives with Alzheimer’s Disease.) last summer. I keep thinking and saying I will go back to the brain when I finish whatever I am currently working on…but as it is…it really is all connected.
