Transcript – Dr. Nadia Maarouf Dialog

David Ariosto – Dr. Nadia Maarouf, it’s nice to see you once more.

Nadia Maarouf – Pleasure is mine, David, it’s been some time, and it’s an absolute pleasure to speak to you once more, and thanks a lot for having me.

David Ariosto – Yeah, yeah. I believe, I believe it’s germane to begin by telling folks the place we met. It might have mentioned Utah on the map, however it seemed like Mars, proper? This was, the truth is, this Mars Desert Analysis Station, which is kind of an analog Mars and habitat within the within the Utah desert. And also you had been the primary individual that that I met, first particular person to greet me upon getting into the have. And I imagine you had been carrying this, like this tech infused headband used to kind of monitor the vitals of the crew. So I’d like to begin there. What, what had been you doing with that headband? What had been you doing there in Utah, in a spot that seemed like Mars.

Nadia Maarouf – Nicely, I used to be the primary crew member to fulfill you, as a result of I used to be the crew medical officer, and as you bear in mind, it was through the pandemic, and so I had to verify to do a fast COVID take a look at to guarantee that we don’t have a compromise of the mission, any person with COVID. I used to be damaging, by the best way, yeah, you was damaging. It was a pleasure to fulfill you, and it was actually fantastic to have you ever with us for a few days, together with EVAs and different actions. So we noticed what we had been doing experiment sensible. So the scarf was a part of a bio monitoring gadget shirt and the scarf referred to as the Astroskin, and that gadget is a part of Canada’s efforts to contribute to autonomic healthcare monitoring, as when when astronauts go to Mars or the moon or any emissions past low Earth orbit.

You may’t depend on Earth centric healthcare methods. So that you so the efforts is to create a bio monitoring, autonomic healthcare gadget that the crew members can can monitor themselves, or in my case, I used to be the principal investigator for that undertaking the place all the crew members had, as you bear in mind, all of us had the headbands and the shirt, and it was the longest steady healthcare monitoring of any crew. So we wore that gadget repeatedly for each 18 days, so 15 days through the mission, after which earlier than and after for baseline.

David Ariosto – Proper, I believe, I believe that is kind of what I wished to speak to you about, within the sense that, like lots of the science that that’s attention-grabbing, lots of science that’s worthwhile, frankly, is that’s people who have kind of these twin software, each in house and right here on earth. And the sense of, , monitoring healthcare methods. I imply, there are gaps on this nation and the world over by which entry to well being care is is restricted. And that doesn’t essentially imply that that that entry needs to be by advantage of know-how. And I believe possibly that’s that’s a spot to go together with this dialog, the sense like, the place that that push into house, has terrestrial functions?

Nadia Maarouf – Oh, completely. So simply going again to that know-how. It’s, it’s the Astroskin. It’s an organization that’s, it’s a Canadian firm, and the goal is to make use of that know-how to watch astronauts touring to longer distances away from Earth. And the goal is to guarantee that when healthcare points come up, then you’ll be able to have contingencies and countermeasures faster, fairly than wait too lengthy. And in flip, you need to use that know-how for, as an illustration, our communities up north that don’t have entry to well being care, and simply mainly present them with with the chance to be monitored, after which in case there’s issues, then you’ve that dwell information for well being care practitioner that may be tons of of miles away, like we.

Had been on the MDRS (Mars Desert Analysis Station), just like the closest hospital was, if I bear in mind appropriately, about 300 miles away. And so I did truly use that, sadly, to floor a few my crew mates when their coronary heart price was too excessive, or considerations about their respiratory charges or temperatures, and many others, to go on EVAs. As a result of in case you bear in mind, you got here with us on a kind of EVAs, and we’re far-off into the desert, we can not danger one of many crew members fainting or having an emergency in the midst of nowhere. In order that was, that was one of many assessments of that know-how for six crew members repeatedly. And, after all, as a result of it was an experiment, I had to make use of it in parallel with the Gold Normal, which is simply assessments each single day, after which speaking it with the Mission Management.

David Ariosto – I believe that additionally kind of betrays, just like the broader, the broader facet of what you’re engaged on, proper? As a result of , it’s one factor to kind of be working in distant areas on Earth, however in house. And this kind of speaks to your work of this, this vaccine that you simply’re engaged on, which is one thing I actually wish to discuss, , in house, micro gravity simply wreaks havoc on the physique, proper? All the things from from bone density loss to muscle atrophy to, like, shifts of fluid inside the physique, , kind of even accelerating gaging of the guts. And so, like, I ponder in case you can possibly sort of get a bit bit extra into the science of what occurs to your physique if you’re in house. And, like, begin focusing there. As a result of, I imply, that is truly topical within the sense that now we have two NASA astronauts, Sunny Williams and Bucha Wilmore, who had been speculated to be in house for per week. And, , they’ve stayed on the station now, the ISS now for for over 250 days. So what’s what’s taking place, what’s taking place to their our bodies?

Nadia Maarouf – Nicely, mainly, each single system within the physique is affected by by house journey and an publicity to microgravity, or beginning by the guts deconditioning for each six months, the guts ages by about 20 years on earth. In fact, it varies individual to individual, and these astronauts are among the healthiest folks on the market, however it does have an effect on folks in mainly each single system. So with the guts, like I discussed, it’s parallel to getting older on Earth and radiation. In fact, there may be larger danger of growing most cancers. There’s imaginative and prescient points, which is expounded to cardiovascular points as effectively. I can, I can dive in a bit bit deeper on that, like we talked concerning the fluid shifting within the higher extremities, as a result of our greatest vessels, just like the aorta and the vena cava, the largest ones are up right here.

David Ariosto – And they also truly begin to reshape a bit bit too, proper?

Nadia Maarouf – Completely, yeah, it reshapes. After which the compliance. To allow them to take into consideration blood vessels within the coronary heart like a balloon. If there may be simply an excessive amount of quantity in there, then the compliance sort of simply deteriorates with time.

David Ariosto – I do know extra of that elasticity. It stays that manner, precisely.

Nadia Maarouf – Yeah. And naturally, that fluid shifting into the higher extremities, it additionally goes as much as the mind. There’s an excessive amount of strain within the skull, it has nowhere to go, and so it begins placing an excessive amount of strain on the optic nerve. Imaginative and prescient begins to have points. For instance, lot of astronauts will expertise what’s referred to as cotton wool imaginative and prescient, which is like simply patches of their imaginative and prescient or bone density goes down rather a lot, between 5 and eight% each month.

David Ariosto – I imply, I believe that is like the larger, greater query, proper? As a result of in case you hear all of the commentary concerning the nature of settlements up there and extended house, and , speaking concerning the Artemis base camp and the Worldwide lunar analysis station that the Chinese language and Russians are placing up there. I imply, all these are centered round having a extra extended and sustained human presence on Earth. And so, just like the know-how appears to be, it looks as if we’re already there, like we are able to do that with the with the kind of equipment, however from the organic standpoint, that’s, that’s a much bigger query, seemingly.

Nadia Maarouf – And so I believe by way of the technological points. That’s the rationale why we aren’t in Mars proper now, technological operational points, however the greatest hurdle is the medical one. And so you can’t ship astronauts to a colony in Mars.So the moon, the moon might be extra affordable, however you can’t hold them there for lengthy sufficient that they’ll do impactful work. Proper now, the requirements are, I believe, one month, steady lifetime spent on the moon for girls, and 40 days for males, if you would like them to nonetheless be wholesome and nonetheless be moral about these folks spending time there. So. In Marc we’re desirous about, , two years simply to get there, if the planets are aligned correctly, I believe by the point they get there, it’s going to be problematic, until you’ve contingencies to forestall these points taking place with each single system within the physique.

David Ariosto – I imply, there are, like, these concepts of making synthetic gravity and kind of these, these rotating buildings up there, and in order that, like may mitigate it. However then you’ve questions on radiation publicity and all kinds of issues that, , simply appear there’s solely a lot testing you are able to do on earth when it on the subject of these items. However, , I wished to really discuss to you about, discuss this vaccine, and so it’s kind of like this cardio protecting vaccine that you simply’re engaged on, , right me if I’m mistaken right here. Nevertheless it looks as if it, it, I bear in mind final time that we talked has to do with what HSP27 which is, just like the chaperone protein, proper, which is kind of protects cells from stress harm. And it’s sort of like, akin to what you may discover in case you go into sauna otherwise you work out, however like, how that, how one can kind of operationalize that by way of of of kind of the broader issues for astronauts once they have, , the shifting fluids, or the strain on on their hearts, or possibly a weakened coronary heart as a result of they’re not working in opposition to that gravity, like, like they do Right here on Earth, and the way that could be utilized, not solely to to astronauts in house, however right here on Earth. As a result of, I imply, it looks as if coronary heart illness is just like the main reason behind loss of life worldwide. I believe in us, I used to be studying us alone, like one in each 5 deaths has been linked to coronary heart illness. So this has like actual functions, not only for kind of the pie within the sky, goals of settlements and such on Mars and the Moon elsewhere, however for on a regular basis people right here on Earth.

Nadia Maarouf – In order as you talked about, simply to present the the viewers a bit background about warmth shock protein 27 it’s chaperone protein that’s protecting in opposition to stress, often, however simply by likelihood, my my prof, found that it’s a foot soldier of estrogen, and in order that’s the rationale why girls often don’t have as many coronary heart assaults in comparison with males, up till the purpose once they attain menopause, after which that’s attention-grabbing, after which it flips, yeah. And so we remoted the warmth shock protein, after which we turned it right into a vaccine. And it’s not a vaccine within the conventional sense. We additionally found that warmth shock protein antibodies kind complicated with warmth shock protein. After which when it’s when the physique is harassed, after we begin to become older, then it sort of releases and supply that safety. And so by way of heart problems, warmth shock protein 27 does two issues. It will increase the expression of low density lipop, or the Yeah, low dusty lipoproteins within the liver. So mainly, it takes away all of the ldl cholesterol, or the unhealthy ldl cholesterol, after which it metabolizes it, as a substitute of simply roaming within the circulation. And the opposite factor it does, it reduces irritation, as a result of with atherosclerosis or the hardening of the blood vessels, you want two issues. You may have excessive ldl cholesterol, no downside. You may have irritation. In fact, there are issues, however then when you’ve the 2 that’s the right recipe for atherosclerosis and illness and ultimately ischemic.

David Ariosto – In order it relates, because it pertains to house, is kind of the intention is that, , as soon as this type of matures and goes via trials that , astronauts would primarily be on condition that. Seen one thing of this kind of push back, particularly in the event that they’re going to be the working house for lengthy durations of time. After which additionally, , it looks as if there’s simply, there’s lots of actually attention-grabbing analysis by way of prescribed drugs that’s taking place in house, within the house atmosphere, . And we’re speaking about, , cells will be cultured in kind of the three dimensional house, with out the necessity for scaffolding, which, like potential permits us to develop like ever extra complicated tissues and organs and all types of recent kind of pharmaceutical and drug makers which are simply sort of growing new applied sciences as we glance to it. So it’s virtually looks as if it’s a I don’t know that is extra of a query, however like, is there a kind of a push and pull right here by way of its each terrestrial functions, but in addition potential improvement in a few of these rising microgravity on orbit labs.

Nadia Maarouf – Completely, I believe with with house applied sciences proper now, there’s some huge cash in in, , making an attempt To seek out options, to seek out options for for healthcare points in house. However in case you clear up that, you then’re fixing lots of points right here on Earth, , together with coronary heart illness. So if there was an curiosity in conducting these experiments in house, that can speed up the data and the info and understanding, after which you’ll be able to return and apply it right here on Earth. And so I believe it goes hand in hand. And so my hope is that there can be a analysis mission the place I can go and do these experiments after which present the info to assist it, after which transfer it sooner, as a result of…

David Ariosto – So that you’re going, you’re going to house, primarily.

Nadia Maarouf – I hope so. I hope so. I imply, you see lots of people go into house as of late, and I, I don’t imply to be damaging, however lots of people go in, , celebrities and so what’s, what’s the contribution that like, what’s the purpose of this mission? I believe transferring ahead, scientists themselves which have designed this experiment ought to go and tax these experiments, as a result of it has has extra affect, for extra optimistic outcomes, for for folks right here on Earth.

David Ariosto – I’d play the satan’s advocate. I believe that possibly the pondering by way of the celebrities and such is simply kind of drum up common curiosity. And that’s the via common curiosity comes larger investments. And, , kind of possibly a normalization of house, however, however you to your level. I imply, you’re completely proper. I truly wish to get, , kind of the final little bit of time that now we have right here to why you determined to to check this. I believe that is simply an enchanting story. I imply, you, you grew up in Morocco, and also you had a father who was, effectively, I’m going to allow you to inform the story, however you had a father that was seemingly pushing you to be empowered in your individual proper, whether or not it’s via stem or some other facets of your life.

Nadia Maarouf – Yeah, so I used to be born and raised in a small rural group in Morocco. Was about 5000 folks at the moment. I believe it’s extra in all probability about 12,000 proper now, and men and women, ladies and boys, didn’t have the identical rights, the identical privileges, together with going to highschool and fear. We will go to highschool. And lots of my my pals in highschool simply get married. Typically they’re considering it. Typically there’s the cultural norms that , you get married in highschool and also you begin a household, or if you wish to go to work, you then do among the jobs, like cashier in administrative jobs, till you develop into a mom, and you then focus in your on your loved ones. I’ve 5 brothers.

My father was, I’m hesitant to say he was a feminist in in a spot the place there weren’t many males that believed that ladies and boys and everyone, if you wish to work for for what you need, then it is best to have that chance. And so he was, he was he was advocating for me to typically I used to be the one lady within the class, and, , attempt to simply remind me that that is, this isn’t regular now, however it might repay later. And so, yeah, I used to be very fortunate to have a father like that who helped me and inspired me to pursue my training. And so he was my hero. I’m fairly positive lots of people assume like that about their dad and mom, however in my case, I believe it was little bit excessive with regards how far he went to verify I had these alternatives. And so I a part of my academic, a part of the necessary issues I needed to do was take one although I used to be 4 years previous once I was enrolled, and that was as a result of he wished me to have the ability to defend myself. Plenty of women and girls, sadly, needed to endure lots of home abuse, and it was sort of people that simply brush it off, like right here, you hear it within the information, however over there, it’s only a day by day wrestle. I moved to the UK after. Phrases, as a result of I knew in Morocco I used to be not going to have the ability to pursue the goals I wished to. I continued with my Taekwondo, and the goal was that I used to be going to complete my undergrad, and I used to be doing very well when taekwondo was 4 occasions nationwide champion, and there have been talks about me going to effectively, not talks.

There have been plans that I used to be going to go to Korea spend the yr, got here again and in for Group GB within the Olympics. However I’ve been to Korea each summer season since 2007 so about 4 occasions, 4 summers in Korea coaching, after which the yr, the top of my undergrad, my taekwondo grasp was a kind of folks you’d meet as soon as in a lifetime, in case you’re fortunate, he was an unbelievable human being, very enthusiastic about taekwondo. He gave me lots of alternatives, together with that one yr coaching in Korea, February, 2010 he had a coronary heart assault on a treadmill after we had been coaching 52 yr previous, wholesome. We thought he was wholesome, however apparently he had some coronary heart points. He handed away. After which I nonetheless went to Korea in finish of Could to begin my yr coaching in 2011 after which come again to the UK to attempt to get into the the Group GB. After which, once I was in Korea, I had a name that my my father was in in within the hospital awaiting coronary heart surgical procedure as a result of he simply had a coronary heart assault. Booked a flight.

I went to Morocco. I went with him via the surgical procedures and all the things. After which I had a light-weight bulb second. You already know, it was two assaults in lower than one yr, folks that I actually, actually, actually liked and cared about, after which I bought right into a grasp’s diploma with the concentrate on cardiovascular pharmacogenomics, as a result of I used to be very considering personalised drugs. And one dimension doesn’t match all. I believe pharmaceutical firms actually like that one dimension suits all, as a result of that’s how they make revenue. However I wished to concentrate on the personalised facets of it. And after that, I yeah, I got here to Canada and was fortunate to get a scholarship to check cardiac sciences with the concentrate on preventive cardiology, as a result of it simply occurred to me that there are statins that are actually PCs, canine inhibitors and all these sort of fancy medication, however they don’t stop coronary heart illness. They only handle it, or they wait till a coronary heart assault happens, after which we simply handle it, and by that point, the guts muscle is already broken, and there’s not a lot to do besides simply handle the illness till the particular person dies, and often with decrease high quality of life. And in order that’s the place this this vaccine got here, got here via. And I’m very fortunate, as a result of lots of people would go their complete life with out doing one thing like that, however I used to be actually, actually fortunate to be concerned with that undertaking, and I’m very hopeful that it’s going to make it to to markets and folks can profit from it all around the world. And I actually hope that, once more, what it doesn’t must be me, however that experiments will be examined in house and convey the info again to Earth to indicate that it’s working or it’s not working, it’s science experiments. We don’t know till we put it to the take a look at, Spoken like

David Ariosto – a real scientist. Dr. Nadia Maarouf, thanks a lot for becoming a member of us right here on Area Minds.

Nadia Maarouf – Pleasure is mine, David. Thanks a lot for having me. I actually admire it.
