The Origins of Renal Physiology, a National Course for Renal Fellows

This fall I attended the fourth annual Origins of Renal Physiology course for nephrology fellows at the Mount Desert Island Biological Laboratory (MDIBL). The course was designed to allow fellows an opportunity to connect with the historical roots of renal physiology and to gain perspective through comparative physiology. The founder of this blog, Nathan Hellman, attended the first course and blogged about his experience in 2008.

The course took place on the coast of Maine at the MDIBL, a place with great historical and modern day significance for renal physiology. George Dorr, who founded Acadia National Park with John D. Rockefeller, had the foresight to recognize the potential value of the island for the scientific community. He offered land for two labs, the MDIBL and the Jackson Laboratory (which also continues to operate on the island with tremendous success). The MDIBL is where E. K. Marshall discovered and described active tubular transport in the goosefish in the 1920’s. It is where Homer Smith wrestled with the concepts of clearance, GFR, and effective renal blood flow and worked out calculations based on his studies in marine animals. He did ground breaking experiments in the lab and wrote a number of manuscripts and books in his cottage on the campus describing these fundamental concepts. For 35 years, he spent his summers working at the MDIBL. Roberts Pitts called this time the “Smithian Era of renal physiology”. Homer Smith brought many others to the island to work on renal physiology, and over the years a number of important discoveries have been made at the MDIBL. The lab continues to be a place of excellence, active in research.

The annual course brings fellows back to this historical place and places them under the mentorship of a distinguished faculty. Mark Zeidel serves as the course director and every year he brings in a remarkable faculty from across the country to distill fundamental concepts of renal physiology in a historical and comparative context. They do this by dividing the course up into six modules. Each fellow participates in three of the six modules with each module lasting for two days. The modules split the kidney up into functional units beginning with the glomerulus and continuing on through the proximal tubule, the loop of Henle, and the distal tubule. They also covered salt and water homeostasis and renal genetics. On the first day of each module, we worked with the faculty in the lab performing experiments using classic physiology model systems such as the toad bladder, the shark rectal gland, the zebrafish, and the xenopus oocyte. We developed a presentation based on our experiments to share with the group on the morning of the second day of each module. Even though we only work with three of the modules each year, we learned what the other groups were doing through the peer presentations. The afternoons after the presentations were spent exploring the island and Acadia National Park. There were organized outings for hiking, biking, and kayaking. We finished the week with a big lobster bake at a park on the seawall.

I have had the great pleasure of attending the course each of the last two years, participating in all six modules. I told my wife when I got home each time that I felt like a kid at camp. Only instead of the usual camp games, we were playing with kidneys and urine. These were tremendous experiences that I will carry with me throughout my career in nephrology. It was great to meet and work with faculty and fellows from across the country. I came away with an enhanced understanding of physiology and a renewed enthusiasm for all things renal. As you make your schedules out for next year, I would encourage you to consider setting aside some time to attend next year’s course, September 2-9.

Surviving lactic acidosis; lessons from turtles

Lactic acidosis is frequently seen in the hospital setting. Diverse etiologies account for the accumulation of lactic acid as reviewed by Nathan last year. The main impetus for the production of lactate is having a hypoxic state either in the entire organism, the cellular level or an isolated vascular bed. Most cells in the body break down glucose to form water and carbon dioxide. This is a two-step process. First, glucose is broken down to pyruvate through glycolysis. Then, mitochondria oxidize the pyruvate into water and carbon dioxide by means of the Krebs cycle and oxidative phosphorylation. This second step requires oxygen. The net result is ATP, the energy carrier used by cells. If oxygen supply is inadequate (hypoxia), the mitochondria are unable to continue ATP synthesis at a rate sufficient to supply the cell with the required ATP. In this situation, glycolysis is increased to provide additional ATP, and the excess pyruvate produced is converted into lactate and released from the cell into the bloodstream, where it accumulates over time.

I met Nathan at the Origin's of Renal Physiology Course at Mount Desert Island, Maine a few years ago. This is an outstanding course where you get hands on experience exploring renal physiology using marine life just as Homer Smith did. I remember learning that the painted turtle, Chrysemys picta is able to survive extreme lactic acidosis. As a renal fellow we are frequently consulted for this devastating entity. Unfortunately, we are mostly unable to intervene as the answer in a majority of these cases is to correct the underlying problem. Interestingly, many aquatic vertebrates can remain submerged underwater for remarkably long periods of time. A prime example is the painted turtle, Chriysemys picta, a freshwater species found in Canada and the U.S. Its natural winter habit is to continuously submerge itself in ice-covered ponds for months. The turtle is able to sustain vital organ function for long periods of time despite severely hypoxic or even anoxic conditions. Lab studies have shown that these turtles an fully recover for submergences lasting 3 months at 3 C. The plasma concentration of lactate have been measured as high at 200mM. How is this possible?

The turtle has adapted to this environment by using several unique mechanisms. First, the major extracellular buffer, bicarbonate, is particularly high at baseline (40 mM) in the plasma as well as the peritoneal fluid (80 mM) and pericardial fluid (120 mM). This however, does not account for all of the buffering capacity needed to sustained such profound acidosis. The second and most interesting mechanism is its use of is bone-like shell. The shell accounts for 32% of the turtles total body mass. The portion of its skeleton not incorporated into the shell represents an additional 5.5%. Besides the obvious role it plays as a protective armor, the turtle's shell is also the major mineral reservoir for the body. Over 99% of the total body calcium, magnesium and phosphate and 60% of the body's sodium reside in the shell and bone.

Two mechanisms account for the shells buffering of lactate. First, supplemental buffers are released from the shell directly when needed. During periods of extreme anoxia. Plasma levels of calcium and magnesium increase dramatically. Likely, this is a passive process by which the shell is demineralized by acids. Mainly, calcium carbonate is released. So much calcium is sequestered in the shell that little loss is evident even with prolonged periods of acidosis. A similar process occurs during untreated acidosis in CKD. However, the calcium stores are not quite as profound in the human body. The second mechanism involves the uptake on lactate and a proton directly by the shell. The enormous buffering capacity of the shell allows for this.

Chriysemys picta's unique habit of hibernating during the winter months have allowed for this interesting ability to survive profound lactic acidosis by using its shell as a buffer. Unfortunately, lactic acidosis in the hospital setting is typically extremely difficult to control as the buffering capacity of the body cannot tolerate lactate accumulation for an extended period of time. Research performed on marine life, like at Mount Desert Island, allow for the discovery of novel and interesting ways to survive extremes in physiology.

Accepting Applications to the Origins of Renal Physiology Course

Nate Hellman, in front of the "Kidney Shed" at Mount Desert Island

The National Course for Renal Fellows: Origins of Renal Physiology course will run from August 30 to September 5, 2015 at the Mount Desert Island Biological Laboratories. Each year renal fellows come to the Acadia coastline to explore the fundamentals of renal physiology with a distinguished faculty drawn from top institutions around the world. Funded by the National Institutes of Health (NIDDK), the course covers the costs of instruction, food and housing for the week.

The application link is here. Applications will close at the end of April.

"The MDIBL Renal Fellows course gave me the opportunity to learn renal physiology from the experts in their fields, in a place where so many important discoveries were made by the giants of nephrology. Collaborating with my peers from programs all over the country, we re-created the experiments that helped characterize ENaC structure and function, osmoregulation, and the complex proximal tubular in a supportive yet intellectually stimulating environment. And when our lab presentations were finished, we enjoyed Acadia National Park and the coast of Maine, by foot and by bike, making great new friends along the way." - Jeffrey William, Fellow, Beth Israel Deaconess Medical Center

This course is a fantastic offering and was life changing for myself and I know many others. Where else can you go to learn about the kidney with fantastic faculty and fellows from all around. This was where I met the late Nate Hellman back in 2008, founder of RFN. You can read some nice blog posts from Nate from the actual course here and if you scroll down here. I would not only highly recommend this course but I would urge you to go. Now that it is supported by the NIH you really have no excuse not to go.

Reporting Live from Mount Desert Island Biological Laboratories

I'm coming to you live for the next week from Mount Desert Island Biological Lab (MDIBL) in Maine, where I'm taking a course entitled "Origins of Renal Physiology."

The course is designed for renal fellows such as myself who seek to establish a career in nephrology research and to discuss the foundations upon which our understanding of renal physiology is based by repeating and expanding upon many of these classic experiments. MDIBL is a small, private lab whose focus is on the physiology of marine animals, many of whom were the model systems for determining such basic phenomena as salt and water homeostasis and how ions are secreted and reabsorbed.

As an example, tomorrow we will do some work on the shark rectal gland. Here is a picture of one of the shark tank at MDIBL:
And here is a picture of what the shark rectal gland looks like:

Why study the shark rectal gland at a kidney course? The shark lives in salt water, where the NaCl concentration is about 600mM, yet their plasma NaCl concentration is only about 200mM. The shark has evolved a mechanism to tolerate such a hyperosmolar environment: its rectal gland, which secretes a massive amount of Na+ and Cl- to maintain its osmolarity. The concentrations of both the Na-K ATPase and the Na-K-2Cl (a.k.a. the "loop Na channel") are exceptionally high in this tissue and therefore these enzymes were initially purified with shark rectal gland as a source, so it has already played an important role in our understanding of renal Na+ and Cl- handling.

I'll be posting more about the experiments we do and the renal lessons I've learned as time allows...

National Course for Renal Fellows; Origins of Renal Physiology

Listen to a podcast from Dr. Mark Zeidel about the Origins of Renal Physiology course at Mount Desert Island held every September in Maine. This course is a great opportunity to learn about renal physiology "hand's on" with world renowned researchers and an even greater opportunity to get to know other fellows from around the country and world. I attended this week long course two years ago with Nate. Many of the attendee's still communicate regularly. The course directors did a great job teaching and keeping the material interesting. Each fellow will get experience in three separate modules focusing on a different segment of the nephron. After a day of experiments and data analysis, the next morning is spent giving presentations about the results obtained. The rest of the day is free to explore the Island. Overall, I thought the course is a unique experience and shouldn't be missed. The course fee continues to drop each year (currently $900- which including food and lodging) and hopefully, as Dr. Zeidel explains in the podcast, the fee might be reduced to free in years to come.

Attention Fellows: Attend the Origins of Renal Physiology Fellows Course 2017

The National Course for Renal Fellows: Origins of Renal Physiology (August 27 – September 3, 2017), is filling up fast.

This 1 week course provides a strong foundation in renal physiology for future renal investigators, teachers and clinicians.

Join 28 of your colleagues from around the country at the Mount Desert Island Biological Laboratories for this highly rated, transformational course.

Origins of Renal Physiology is entirely unique among national renal short courses. The course provides participants with research tools that give them a deeper understanding of concepts of physiological homeostasis which is difficult to attain during normal clinical training schedules. In this course, trainees will perform experiments involving both classical physiological models, as well as modern reductionist approaches and confocal microscopy to follow trafficking of transporter proteins in cultured cells. In addition to the curriculum itself, fellows will benefit from close interactions with senior investigators in renal physiology, who will guide them through the performance of the experiments, share meals with them in the dining room, and take the time to discuss their career goals with them. In addition, fellows will benefit enormously by working closely with other fellows from different programs, and sharing their insights into renal research. The course is organized around several laboratory modules and one enrichment module in Responsible Conduct of Research. Participants will complete three of the rotations over the six-day course. The first day of each rotation involves intensive experimental work, and the second day involves analysis and presentation of the work to the entire conference group.

Apply here. 

Note: This is a fantastic opportunity. Don't even think twice about it. SIGN UP and GO!!! I would go back in a heartbeat. Matt Sparks (2008 Alum)

ASN launches renal fellow website

The American Society of Nephrology (ASN) announced the creation of a "fellow's" website today. You can locate this site by following the link or going to the "training" tab of the main ASN website (www.asn-online.org). The ASN fellow's webpage contains many useful resources for Renal fellows with plans to add more in the future. A link is provided with grant opportunities specifically geared to Renal fellows from government, non-profit and private organizations. Different educational opportunities are highlighted as well. From conferences to courses to the Mount Desert Island National Course for Renal Fellows (The Origins of Renal Physiology). A touching tribute to Nathan Hellman is included with a link to Renal Fellow Network. This site is a welcome resource for Renal fellows navigating the busy fellowship program. Much of the information provided on this site used to be passed down from fellow to fellow. Now we have a portal where all types of resources can be immediately accessed. Cheers to the ASN for making this site.

Major Plug for MDIBL Origins of Renal Physiology Course

Today wrapped up the inaugural Origins of Renal Physiology course at Mount Desert Island Biological Laboratory. It's the first time this has been tried, and though there was significant uncertainty in my mind about what the course would entail, I am really glad that I had participated and I feel most consider it a definite success. I would highly recommend this course to other renal fellows--both those who are interested in a career in research as well as those with a more clinical bent.

In summary, the course included 6 modules on core topics in renal physiology, which included The Glomerulus, the Proximal Tubule, the Thick Ascending Limb, Understanding ENac, Water Metabolism, and (my personal favorite) a module on Salt Secretion using the shark rectal gland as a model system (allowing me to wrestle with an actual shark, as shown above). Each module is headed by a scientist (some nephrologists, some PhDs) with a special expertise in that area, and small groups are given the opportunity to design and carry out their own experiments. Each module was well-organized and in most cases, post-docs or lab technicians were readily available to help carry out experiments on a practical level. Every other day there is a large group meeting in which each module's renal fellows describes their results in the form of brief presentations.

We worked pretty hard on many of the experiments, staying up well past midnight on some nights, but there is also adequate time allotted for exploring the amazing Maine outdoors. The lab is situated within a few miles of Acadia National Forest, and every other day there is some type of group outing planned, such as hiking, biking, or kayaking. This was a fantastic experience.

1000th Post

In celebration of our 1000th post, we asked Matt Sparks. a former editor of the Renal Fellow Network who is now a faculty member at Duke University in North Carolina for his perspective on his time with this blog. RFN began as the work of one outstanding fellow at MGH and has grown into a collaboration with contributors from around the US (and further afield). Here's to the next 1000 posts. Take it away Matt...

The Renal Fellow Network has provided a substantial influence to my young career as a nephrologist. First and foremost I want to recognize the role Nate Hellman played in founding and inspiring both RFN and the entire online nephrology community into what it is today. Without Nate's efforts RFN would have never even existed. I first met Nate back in 2008 at the inaugural Mount Desert Island Renal Fellows Course; Origins of Renal Physiology. He told me about his blog which he had already aptly named Renal Fellow Network. I visited RFN frequently and found his daily updates extremely helpful and interesting. I'm still in awe of how he was able to generate a new post on almost a DAILY basis. 

After his untimely death in 2010 I felt that this incredible resource needed to continue. I contacted Conall O'Seaghdha and told him that I was interested in helping keep the site going. This turned out to be an exciting, rewarding and sometimes challenging experience. I quickly realized that RFN was an important resource for  fellows, physicians, medical students, healthcare workers and importantly patients all over the world. I was shocked how far and wide our reach was. During the time I was deputy editor of RFN I learned so much about nephrology, science and people. RFN has a unique perspective to offer. Fellows are writing educational pieces about information that they are just being exposed to. In essence these are "real time" accounts of the learning process itself. This is truly refreshing for the reader of the blog. No preconceived biases or self promotion. We always strive to make sure the science discussed on RFN is accurate with appropriate citations provided when necessary. However, keeping the site going was sometimes challenging. We were always looking for new fellows from around the US and world to contribute. We solicited help from the major nephrology societies to provide administrative help and I personally want to thank the National Kidney Foundation for their support. 

Personally, I have benefited tremendously from my interactions of many individuals on RFN. I have formed many friendships and collaborations from both RFN colleagues and the online nephrology community. My plea is for current renal fellows to get involved. The Renal Fellow Network was a gift that Nate Hellman gave to us. Let's keep RFN going strong. Share what you are learning with the community. You will be surprised how rewarding this can be. Cheers to the 1000th post on RFN. This is truly an accomplishment. Let there be many more.

Origins of Renal Physiology

Every year we like to publicize the MDIBL origins of renal physiology course. This is a great opportunity for renal fellows and the fact that it is free apart from transportation costs is a huge bonus. This is a message from the course director:

From Fish To Philosopher

Homer Smith is considered the Father of Renal Physiology. He was a PhD (rather than an MD) whose studies on the fish renal system are amongst the first renal physiology experiments. For instance, his work on the goosefish (the funny-lookin' fish pictured to the left), which is aglomerular and therefore relies purely on tubular function for clearance, helped establish the important concepts of secretion and reabsorption as fundamental processes of renal function. Much of his work was done here at Mount Desert Island Biological Laboratory, in a small building right by the ocean called "The Kidney Shed."

Nearby the "Kidney Shed" there is a cute, cell biology-themed fence--which incorporates not only a membrane phospholipid bilayer, but also the Na-K ATPase (in my mind, one of the defining molecules of Nephrology) and the endothelin receptor (complete with 7 transmembrane-spanning segments!)

Origins of Renal Physiology at MDIBL Continues to Inspire Nephrology Fellows

2017 MDIBL Origins of Renal Physiology National Renal Fellows Course

I first discovered the Origins of Renal Physiology course on Renal Fellow Network as a medicine intern, and ever since that time, dreamt of going to the course as a renal fellow. Nate’s picture in front of the “Kidney Shed” was seared in my mind. The dream finally came true two weeks ago when I set foot on the Mount Desert Island Biological Lab (MDIBL) in Coastal Maine, and the first place I visited was indeed the Kidney Shed.

Can't believe I am finally here ! This place is gorgeous!! @Nephro_Sparks @RenalFellowNtwk pic.twitter.com/XgOyShoaQg

— Manasi (@manasib33) August 26, 2017

In his opening address to the fellows attending the course, Dr. Ziedel rightly said “Physiology is the pride of Nephrology”. He went on to mention the names of several luminaries who have worked at the MDIBL leading to many important discoveries. The lab has been a cornerstone of nephrology research and has been a home for the work of Homer Smith, E.K Marshall, David Evans, Franklin Epstein, and many others who have spent years working on and elucidating the fundamental concepts on kidney physiology.

In modern day practice of nephrology, we are less exposed to these fundamentals of kidney physiology that initially piqued our interest in nephrology. The Origins course is one of the many efforts made by the renal community to reconnect nephrolgoy fellows to physiology. It’s a very unique course which gives the fellows an opportunity to rub elbows with senior and distinguished renal physiologists from esteemed institutions and work with them on experiments to understand the different aspects of kidney biology.

The course consisted of 7 modules, each focusing on a functional unit of the nephron- the glomerulus, proximal tubule, thick ascending limb, distal tubule, acid-base, water homeostasis, and chloride secretion. We studied animals like zebrafish, turtles, and toad bladders. We also explored how ENaC and NKCC channels work. We delved into discussion about morpholinos and so much more. Over the duration of the course, we developed a new-found appreciation for the beauty and wonder of exploring how the kidney regulates homeostasis. We also got a sense for the profound impact MDIBL has had on the field of nephrology and physiology.

As MDIBL is in such close proximity to Acadia National Park- one of the most beautiful national parks in the world, nature is inherently embedded in the process of learning here. Most days started off with a refreshing early morning short hike which energized us to spend the entire day in the lab. On alternate days, amazing outdoor activities were planned for us after presentations of the earlier day’s work. My week at the MDIBL during this course was very memorable.

I was honored to be working closely with great mentors and met nephrology fellows from all over the US and abroad, shared interests and future aspirations and found new friends. 

All in all, an incredible experience! I would wholeheartedly endorse this conference for future fellows.

ATTN Nephrology Fellows: Origins of Renal Physiology fellows course now open for applications

Jeff during a trip to MDIBL

As a senior resident at the Beth Israel Deaconess Medical Center, I was fortunate enough to have had the opportunity to attend the Mount Desert Island Biological Laboratories even before I knew there a course for Renal fellows. It was there that I learned of the importance of comparative physiology in our understanding of the Renal physiology we see every day as nephrologists. For anyone who has attended the Renal Fellows course at MDIBL, the Animal House region of this year's NephMadness undoubtedly made you smile. In fact, choosing a winner was like picking your favorite child. How could you decide between how toads and camels solve their osmolality problems?! They didn't even mention why seagulls "spit" (they excrete salty fluid that drips onto their beaks...and it flies off when they shake their heads!). See what you're missing?

5 years after my first trip to MDIBL, I have been back every year since, teaching in the BIDMC and Hospitalist courses. But I will always have a special place in my heart for the Renal Fellows course, where I learned more in 1 week about basic science, renal physiology, and how lucky I was to be a future nephrologist than I ever thought. We worked hard...and we played hard. When not in the lab, we were exploring Acadia National Park on foot and on bicycle, eating obscene amounts of shellfish in Bar Harbor, and getting to know our fellow fellows and some of the most influential physician-scientists in the field.

In fact, I loved the course so much that I decided to study it! Here is our published paper about just how great the Renal Fellows course is So here's the deal,...if you want to go, you have to APPLY. Your course tuition is on the house! (the NIDDK is footing the bill). This year, it's happening from August 18th through 25th.

National Course for Renal Fellows: Origins of Renal Physiology September 3-10, 2011

Places are still open for renal fellows to join the Mount Desert Island Biological Laboratories, near Acadia National Park in Maine, for this 1 week course. Taught by nationally prominent renal physiologists (who are also superb teachers), trainees perform classical and cutting edge experiments using mostly marine models, and share their results with each other in joint laboratory meetings. Each trainee participates in three of the seven modules, and hears about all modules at the lab meetings. As a result, trainees develop a thorough understanding of the physiology of the nephron, from the glomerulus through the collecting duct. The course provides researchers with a broad perspective on renal physiology, and, by linking basic physiology to clinical nephrology, helps future educators to become better teachers of clinical nephrology.


The course has run 4 times, and has received extremely favorable reviews from all who have taken it. Nate and Matt both took the course blogged about it here, here and here. For those of you who have not taken the course, you can apply here.
