Well I think we've made it to the point of satisfaction. I'm proud enough with her to add her to my body. Well wish me luck. Now comes the harder part. Wish me luck.

It's always a bonus when I run into a tattoo artist somewhere other than a tattoo shop.

For example, I spotted Matthew Adams on the platform of the 34th Street Station, waiting for a downtown A train last week.

Like most artists, he had a lot of ink, so he picked this one piece to share:

And on the back side of the forearm:

Matt works at Sacred Tattoo in Manhattan with Lalo Yunda, who is the artist that inked this incredible skull.

As it turns out, I have featured Matt's work on the site before here and here, as well as this piece by Lalo.

Thanks to Matt for sharing this great tattoo with us here on Tattoosday!

Tattoos in Film: Tattoo

zzzZZZZZZRRRRrrreeeekkkk!!!! The sound of a tattoo machine can be intimidating but it isn't very often the tattoo artist is a crazed maniac obsessed with covering your entire body with tattoos.

In the 1981 thriller Tattoo, Bruce Dern plays Karl Kinsky, a soft spoken tattoo artist who is commissioned to paint temporary tattoos on models for a fashion shoot (wink, wink). Maddy is one of the models and is intrigued with the mysterious tattoo artist. Karl quickly becomes obsessed with her beauty, his perfect canvas. Determined to have her wear his eternal mark, she is kidnapped and held hostage. While she is in captivity, Karl completes his full body masterpiece. After viewing her tattoo covered body, Maddy devises a plan to escape, ending in a deadly fight for freedom.

Discovering this movie had a profound influence on my career. The idea of someone creating temporary tattoos for films blew my mind! As a young artist still finding my voice, I began working closely with Temptu, the original creators of the tattoos in film. I fell madly in love with the endless possibilities of temporary tattoos. Through the years, I have dedicated my skills to developing a unique niche of creating tattoo imagery both on and off the camera. So far I haven't kidnapped anyone...or have I?

Marianna Shares the First Rose of Spring

Today is the first day of spring! It's always a joyous time here at Tattoosday, as the temperatures rise and all the tattoos of my fellow New Yorkers come out of hibernation.

Last week we were experiencing a lovely end-of-winter day with warm temperatures and I encountered this lovely first rose of spring on the F train:

This rose, on the upper left arm of a woman named Marianna, was just popping off of her skin having been freshly inked the day before by the talented Eli Quinters at Smith Street Tattoo Parlour in Brooklyn. Eli's work has appeared previously on Tattoosday here and here.

Marianna had a lot of other interesting work in progress going on, so perhaps we shall see more from her in the future. In the mean time, however, we have this lovely rose which she offered up in celebration of the end of winter.

Thanks to Marianna for sharing her beautiful flower with us here on Tattoosday!

Musician Monday: Camille Harp's Bird Flies Free

It has been a while since we celebrated "Musician Monday," but the early onset of spring has brought out the tattoos and last week in Penn station, I met Camille, who shared this part of her left sleeve:

We focused on this segment in particular:

Camille told me she went to her artist, Fernando Casillas, at Think Ink Tattoo in Norman, Oklahoma, and just told him she wanted a bird flying out of a cage. "I just like the idea of setting yourself free," she explained. Work from Think Ink has appeared on Tattoosday previously, here.

It wasn't until the following day, when I noticed that Camille had followed us on Twitter, that I realized that she was a musician. I had caught her while she was heading back to Oklahoma, and was nervous about catching the right train and making her flight in time.

Camille, as it turns out, is Camille Harp, a singer-songwriter from a musical family, who has an album forthcoming called "Little Bit of Light". If you go to CamilleHarp.com, you can download her song "One by One". It's a lovely song that only makes me wish I could hear her in concert. She has a wonderful voice and soulful tone.

You can also grab her record "Like the Rain" here.

Thanks to Camille for sharing her tattoo with us here on Tattoosday! Please check out her website and/or her fan page on Facebook and support this wonderful artist!

We'll leave you with a performance from 2010, in which Camille sings with her mother in Oklahoma City:

Subtle Hedrix

I've decided to tighten a couple of old pieces. Not sure there where they want to be but she is coming along. Wish me luck.

Jason's Two Stars Lead the Way

Last week, I spotted Jason walking through Penn Station and took the opportunity to ask him about some of his tattoos. He says he has about twenty-four in all, so I took a picture of his forearms, from the photo here you can see six of them, including a Celtic knot and the phrase "Let it be...".

However, Jason drew my attention to the two stars, which were his first two tattoos. I'll let Jason explain, in his own words:

"The crumbling star was originally meant for my broken aspirations, something I dreamt up when I was a kid. And then, the outline of the green star ... the green, for me, it means rejuvenation, you know, new ideas, new paths, just different things to inspire me."

The two stars were not done at the same time, but the crumbling star was inked at Addiction NYC in the East Village. The green star followed a couple weeks later and was completed in Brooklyn, at Inkman Tattoo Studio.

Jason told me he likes to get new tattoos when he travels, what I like to call a "tattoorist," if you will. New ink is always a great way to commemorate places one has visited.

Thanks to Jason for sharing these two stars with us here on Tattoosday!

Tattoos in Film: Eastern Promises

In Russian prisons, a man's entire life is written on his body. Without tattoos he does not exist. Most Russian criminals carry a collection complex symbols which involve a great deal of detailed information giving full disclosure of their family life and past criminal activities. The placement of these marks on the body hold just as much significance as the symbols themselves.

Similar to other members of organized crime, the Russian Mafia uses tattoos to identify it's members and their ranking status. Boasting of unearned tattoos is a punishable offense leading to involuntarily removal of painful acid procedures. Forceable tattoos to the forehead is a common source of punishment to publicly humiliate and clearly identify those who have broke the "criminal code".

The gritty reality of these marks in the criminal underworld are brought to light in the movie Eastern Promises. The story begins with the heartbreaking journey from the diary of a pregnant Russian teenage prostitute who dies during childbirth. After discovering the journal, a determined mid-wife follows the clues that lead to revealing the girls rape, drug use and involvement with the Russian Mafia.

Viggo Mortensen portrays a Russian gangster using his body as a criminal storybook. Each tattoo on his body represents the details of his background and imprisonments that eventual achieve a new ranking in the mob family. This on-screen tattoo process was one of the most authentic I have seen in a film.

Steve's Zombie Apocalypse - In Progress

A couple weeks back, on an unseasonably warm and sunny February day, I spotted Steve on Penn Plaza, wearing a short-sleeve shirt, with some pretty cool ink peeking out from his arm.

Intrigued, I approached him, and started up a conversation about his tattoos. He showed me several pieces, including this, a back piece that is in progress:

Take a closer look - this is pretty cool. I spoke to Steve at length about his work. He had recently left the U.S. Marines, where he had been stationed overseas in Japan. It was there that he chanced upon an artist named Aya, at a shop called Silent Ink, located in the city of Iwakuni.

As Steve, explained it, Aya is a deaf-mute (thus the shop name) and he became a huge fan of her work while serving in Japan. "It's a full zombie apocalypse scene," he told me, and he plans to fly out to Washington State when Aya next travels to see her fiance in the U.S., so she can complete the work.

I always defer to the contributor, as to whether they want to share work in progress, and Steve had no qualms about letting us see this early stage of the back piece. I was able to get a closer look at the completed sections:

I just love the colors and shading behind the tree that borders the upper right arm:

Steve estimates that she has already spent approximately 38 hours on his canvas over several sittings. "I like to sit for a long time," he told me. I certainly look forward to hearing back from him when Aya has completed this work!

Thanks to Steve for sharing his ink with us here on Tattoosday!

Inkbursts: Spring Awakening

So I'm digging these inkbursts for now. This is the third in the series, each piece composed on the New York City subways.

On Thursday it was 60 degrees in the Big Apple and, I read somewhere that this has been the fourth warmest winter on record. You wouldn't know that from the paucity of posts these last few months, but that doesn't mean I haven't been busy.

We had a bat mitzvah to throw in February, and I have been working behind the scenes recruiting contributors for our upcoming fourth annual Tattooed Poets Project in April. To which I can exclaim, "More poets! More tattoos! More FUN!"

I used to feel guilty about letting a day go by post-less. I pictured inked fans worldwide waking up bright-eyed and bushy-tailed, only to be gravely disheartened by yet another day gone by without a new Tattoosday post. No more. This blog is neither the center of my universe, nor a viable way to help support a family of four. I have come to terms with that.

But, with spring rapidly approaching and blog traffic at an all-time high (50,000+ visits per month in January and February!), I am in high spirits and am hoping to do a lot of great things with Tattoosday in the months to come. Thank you for checking in and checking us out!

Regulation of pyruvate oxidation (part 2)

The pyruvate dehydrogenase complex activity is regulated mainly by two distinct mechanisms – allosteric mechanisms and reversible covalent modification.

In fact, there are some allosteric modulators of the complex, which in this particular case belong to the class of negative modulators, ie, inhibitors of its catalytic activity:

- Acetyl-CoA – it is the product of the reaction, thus, it makes sense that the molecule of acetyl-CoA has an inhibitory effect on its own synthesis

- NADH – one of the products of the reaction is NADH, so the reasoning is equivalent to that carried over to the acetyl-CoA molecule. Furthermore, as already mentioned in other posts of this blog, NADH may be involved in ATP synthesis (in cellular respiration), so, its presence indicates a potential for a high energy state into the cell. Accordingly, and as the oxidation of pyruvate to acetyl-CoA is part of catabolism, whose main objective is to obtain energy, it makes sense that NADH inhibits catabolism and, in particular, this reaction.

Regarding the reversible covalent modification, this enzyme complex is inhibited by phosphorylation and activated by dephosphorylation. This process is mediated by two different enzymes… The one that phosphorylates is called pyruvate dehydrogenase kinase, whereas the one that dephosphorylates it is the pyruvate dehydrogenase phosphatase.

Factors that activate the kinase, leading to the phosphorylation of pyruvate dehydrogenase complex (ie, inhibitors of its catalytic activity):

- Acetyl-CoA and NADH – in addition to its direct effects on the pyruvate dehydrogenase complex, as allosteric inhibitors, these two molecules also trigger the phosphorylation of the complex, promoting its inhibition, which means that they can act, therefore, through two distinct mechanisms

Factors that inhibit the kinase, favoring the balance towards the dephosphorylated form of pyruvate dehydrogenase complex (ie, activating its catalytic activity):

- NAD⁺ – for this molecule it can be done the reverse rationale made for NADH. That is, the presence of NAD⁺ indicates an energy deficit on the cell, so it is needed to activate the catabolism to counteract this deficit.

- ADP – the reasoning is equivalent to the one mentioned above, as to say that the cell is accumulating ADP means that it is spending ATP. Thus, it will need to produce again ATP

- Pyruvate – pyruvate is the substrate of the reaction, and its presence will activate the pyruvate dehydrogenase complex by inhibiting the phosphorylation process (and thus its inhibition) of the pyruvate dehydrogenase complex

- Coenzyme A (CoA) – this cofactor plays a co-substrate role, so that its presence will affect catalytic activity of the complex in a similar manner to that described for pyruvate

Factors that activate the phosphatase, leading to dephosphorylation of pyruvate dehydrogenase complex (ie, activating its catalytic activity):

- Ca²⁺ - calcium ion is an important modulator of the metabolism. In this particular case, this ion acts (in the muscle) at the level of pyruvate dehydrogenase phosphatase, activating it (by promoting its dephosphorylation). Put simply, the calcium ion is an indicator of muscle contraction, so it makes perfect sense that in the context of working muscles, the catabolism becomes active, so that there is ATP available for the process
