An Interview with Dr. Tobias Marton - MSS Speaker 11/9/16

By Shoshana Harlem, Terra Linda High School

Did you know that each year about 20 million people in the United States get diagnosed with depression? Worldwide, more than 350 million people suffer from depression. Depression is a mental illness where a person's sadness lasts more than two weeks. Depression can lead to all sorts of problems including suicide. Dr. Tobias Marton, Assistant Professor at UCSF, studies and helps people who suffer from depression.

In advance of his talk at TLHS, he provided the following information:


1. What made you become interested in being a Psychiatrist and studying depression?

 I became interested in medicine and biology during my junior year of high school while taking AP biology and harboring a mild obsession with the hit TV show ER. Prior to then, I really hadn’t thought too much about becoming a scientist or doctor and was actually much more interested in history and music. The summer between my junior and senior year I was able to get an internship working at a local biotech company that studied genes relevant to neurobiology, and from then on I became very interested in the complexity of the brain. I worked in a couple of different neurobiology research labs during my undergraduate years at Berkeley while taking my premed courses and knew I wanted to practice medicine in either neurology or psychiatry because they both involved different aspects of brain function. It became clear to me during medical school that I was a natural fit for psychiatry because I really enjoyed talking to people and trying to understand their stories and how they came to be who they are today, in addition to having a good temperament in sitting with patients that can pose behavioral challenges.

My interest in studying and treating depression really developed during my psychiatry residency. Depression is very common across all age groups, genders and socioeconomic groups and it’s also a leading cause of suicide in the United States. Many mental health professionals regard the current situation with depression and suicide in the U.S. as a public health crisis, and yet it’s not an illness that we as a society are comfortable discussing and addressing in the open, like we do with other diseases such as cancer and heart disease. We’ve made considerable advances in the last decade in our understanding of the brain and how it changes during depressive illness. These insights are starting to generate new treatments that I am excited to help bring to our patients and their families.

2. What is it about your work that led, you to be given the National Institute of Mental Health Outstanding Resident Award in 2012? 

The National Institutes of Mental Health (NIMH) are very committed to supporting psychiatrists with scientific training in developing a career as a physician-scientist in order to help bring new treatments to patients struggling with mental illness. Based on the quality of my PhD work, I was identified by the NIMH during my residency as someone whom they wanted to support and encourage to continue in psychiatric research.

3. What are the hardest parts of your job?

At a very basic level, the practice of medicine is to sit with, and help alleviate, human suffering on a daily basis. For most physicians, this is the very reason we chose a career in medicine and feel it is a great privilege to be present with a patient and family during times of suffering. That being said, this can be an emotionally and physically exhausting line of work. To have a sustainable career in medicine and avoid burnout, it’s really important to have a balanced, positive and rejuvenating life outside of the hospital. Finding that balance on a daily basis is crucial to one’s personal job satisfaction and happiness and is also a constant challenge to maintain.

4. What kind of research are you currently working on?

Currently I am working on publishing some research I conducted during my research fellowship which used optogenetic technology to study the neural circuitry of the prefrontal cortex in mice during a cognitively challenging task. I am also getting started now on a project at San Francisco VA with Dr. Wallace (former Marin Science Seminar speaker) which will investigate the effects of ketamine administration on blood flow to prefrontal cortex in patients with treatment-resistant depression.

5. What advice would you give to people who are suffering from depression?


The biggest challenge mental health professionals face in treating depression and preventing suicide is that many people suffering from depression and suicidal thoughts never seek help. The important thing to know is that there are many effective treatments available that can really help people feel better and like their best selves again, so there is no need to continue suffering in silence. Seek help! Recovery is very possible but only if you make the first step to reach out for help – this first step could include talking to family members, counselors, teachers or your primary physician who can then start the referral process to a mental health professional. You can always call the National Suicide Prevention Lifeline at 1-800-273-8255 which is staffed 24 hours/day. The National Alliance on Mental Illness (NAMI – www.nami.org) is also a great organization with many resources available on line and in person.

An Interview with Dr. Maggie Louie

By Zack Griggy, San Marin HS

           Cancer is a widespread problem. The American Cancer Society estimates that this year over 1.6 million Americans will be diagnosed with cancer and another half a million are expected to die from it. Dr. Maggie Louie is an experienced researcher in the fields of cancer. Currently, she runs an active cancer research center that studies breast cancer.

To find out more about Dr. Louie's work and her research, we conducted an interview:

1. How did you first become interested in studying cancer?

I did a medical internship the summer of my junior year in high school and I got to shadow two surgeons.  One of the surgeries that I observed was a 40-year cancer patient undergo double mastectomy.  At the age of 16, just thinking about how breast cancer can take away an organ that partly defines someone's women-hood had a significant effect on me.  At that moment, I became quite interested in cancer.

2. What studies have you conducted in the past? How have they led you to where you are today?

My lab has conducted many studies.  One of the studies that we did was to study how exposure to chronic low-levels of cadmium impacts on progression of the disease.  Our results show that even at low levels, cadmium promotes more aggressive cancer characteristics and alters the gene expression patterns of the cancer cells.

3. How is tamoxifen used to treat breast cancer? How does a tumor develop resistance to it?

Tamoxifen is an estrogen receptor antagonist and blocks estrogen from activating the receptor and promoting breast cancer growth.

 4. How do metals such as cadmium activate estrogen receptors? How might these metals influence the development of a tumor?

Cadmium is a metalloestrogen and is known to bind and activate the estrogen receptor.  It has also been shown to promote breast cancer growth While we know that heavy metals like cadmium promote cancer growth, scientists are still working to understand how it works.

5. What are the best parts of your job? What are the worst?

The best parts of my job are working with students and using research to inspire them to be interested in science.  The less attractive side of my job is that research is very repetitive and redundant, and sometimes you don't see an impact for many years.

6. And finally, do you have any advice for students who aspire to study cancer?

 Students should definitely consider studying cancer as this disease will touch everyone in some way, directly or indirectly, and they will be making a difference.

September 21: "Myths of Astronomy" with Thomas Targett PhD of Sonoma State University
Check it out on Facebook

Much of what we think we know about space often comes from film and television, but Hollywood's job is more often to entertain than to educate. In this presentation, Prof. Thomas Targett of Sonoma State university will sort fact from fiction, taking a tour through the worlds of Star Trek, Star Wars, and much more.

Thomas Targett obtained his undergraduate and masters degrees from Cardiff University, in Wales U.K., with a
research focus on 21-cm emission from neutral hydrogen. He obtained his PhD from the University of Edinburgh, Scotland, in the fields of sub-millimeter galaxy evolution and the coupled growth of galaxies and black holes. In 2007 Dr. Targett began a research postdoc at Caltech, followed by similar appointments at the University of Birmingham (UK), the University of British Colombia, and the University of Edinburgh. He is currently an Associate Professor of Astronomy and Physics at Sonoma State University.

Space Travel: How Does Outer Space Affect Your Body?

By Rachael Metzger, MSS Intern

          Have you ever wanted to become an astronaut? Travel to space? Have you dreamed about finding extraterrestrial life or communing with aliens? If your answer is yes, I can assure you that you’re not alone. Countless children dream of becoming astronauts, and many movies and TV shows have revolved around exploring space. The exploration of the unknown is a wonderful idea on paper, but it is a lot more complicated than jumping into a spaceship and traveling to Mars, even if we have the technology to do so. Space travel can take a huge toll on a human’s body if certain precautions are not taken; any error could result in death.
        The human body was not made to travel in space, nor has it had time to adapt to such an environment. When launched into space, some effects of that changed environment on the body take longer than others to be felt. Immediately one might experience nausea and/ or vomiting. This is caused by the sensitivity of the inner ear which affects balance and orientation. Thankfully, in a couple of days the inner ear will have adapted to the new environment and the nausea will dissipate (BBC “future”).
        In about two days, bodily fluids will rise to the upper body and face, causing a bloated appearance, and tissues will swell in the head, making a person feel like they are hanging upside down. This makes the body think that it is over-hydrated and it forces the liquid out through urine, causing astronauts to have 20% less fluids in their body while in space.  
Bodily Fluids in Space 
        Spaceflight can also quickly affect eyesight, creating anomalies such as optic nerve swelling, retinal changes in the shape of the eye, and other negative effects to the eye 
        In a week’s time muscle and bone loss can start to occur, and this sometimes includes heart muscle because not as much effort is needed to pump blood in anti-gravity. The lack of gravity can have such an extreme effect on bones that they can become very brittle; this is called “disuse osteoporosis” (The Dallas Morning News “Preparing Bodies for Liftoff”). Even astronauts' skin will get thinner, making them more prone to cuts and infections which take longer to heal in space. Sleep deprivation is another problem among astronauts. Because of the change in the light-dark cycle, it can be a challenge for the body to adapt to the new sleeping schedule (NASA).  
The Effects of Space Travel on the Body

       After a while aboard a spacecraft, astronauts may find their immune system becoming less effective, making them more susceptible to diseases. Cosmic radiation is another huge issue facing astronauts. Astronauts seeing flashes of light in their brains is proof of the cosmic radiation. Astronauts' brains could suffer brain damage from cosmic rays over long periods in deep space, affecting their mental performance (BBC "future").
        All these dangers could be fatal and might make space travel seem impossible, but there are many precautions being taken to allow us to explore our universe in a safer way. Nausea and vomiting can not always be avoided, but anti-nausea pills and a strong stomach help towards inner ear balance in space. To battle losing 20% of bodily fluids, astronauts must stay well hydrated while their bodies adjust to the new climate. The rising of bodily fluids to the upper body may be uncomfortable but has not  been linked to long lasting negative effects on astronauts, and it subsides after a couple of days. Bone and muscle loss is one of the largest problems facing astronauts. On the International Space Station, astronauts stay fit with a machine for weight lifting, a treadmill adapted for microgravity, and a Cyclergometer, which is a modified cycler for microgravity (NASA). Astronauts have a very strict sleeping schedule to try and achieve the maximum hours of sleep possible. Astronauts have to be very careful of keeping waste and bacteria contained that could contaminate their lowered immune systems. For long expeditions such as to Mars, radiation  protection is being experimented with in the forms of water, waste, plastic, and many other substances.
         Being an astronaut involves more than just knowing about your area of study, it requires knowledge of how the human body operates. If your dream is to become an astronaut, consider the risks, know about your body, but don’t be scared off. Medical and technological advances continue to make space flight safer and easier on the human body, presenting an opportunity to explore space to a further extent.
