Postbac Life: A Week in an IRP Lab

What does a postbac actually do in the NIH IRP? Maybe you have an image of someone mixing colorful chemicals together like a mad scientist (which sometimes isn’t too far from the truth).

Although I am not creating any diabolical concoctions, I am kept quite busy running tests to examine whether our treatments reverse the effects of lung fibrosis, a thickening and scarring of lung tissue. Here’s what a typical week looks like for me.

Cholesterol Molecule Yields Insights Into Distressed Lungs

Potential biomarker may contribute to personalized treatments

Until recently, medical treatment has largely been one-size-fits-all, with doctors unable to separate patients into distinct groups that might benefit more or less from a particular approach. However, researchers are increasingly finding that individuals with the same disease can differ markedly in ways that might one day influence their care. A recent IRP study has identified a particular molecule that may have just such an impact for patients with damaged lungs.

Postbac Life: Wading Into Drug Discovery Research

“That machine? You’re gonna have to get up close and personal with it,” Josh, my fellow postbac, told me. I looked at this small metal contraption and nodded, trying to appear as if I understood, while thinking: he just means that people spend so much time sectioning organs on the microtome that it’s like spending an extended amount of time with a loved one, right?

Fast forward a few days, and I find myself breathing warm, moist air onto a paraffin-embedded mouse lung to soften the wax, just before I slice four-micrometer sections of mouse lung tissue that will later be stained and examined under a microscope. “He wasn’t kidding,” I muttered.

Life of a Postbac: My Experience Joining the NIH Family

It was picture day, and I sat stiffly in front of a wrinkly blue curtain, nervously patting my hair into place. “You can smile, but just make sure no teeth are showing,” the person taking my picture told me. I laughed at that, and she also laughed, adding, “Everyone gets a good chuckle out of that one,” as she snapped my photo. A few days later, I picked up my photo, printed (not so) nicely with a vertical stripe running down my face. I didn’t even notice. I thought, this is real, as I proudly held up my official NIH ID badge.

Remembrances: Theodor Kolobow (1931-2018)

Dr. Theodor Kolobow

Theodor Kolobow, M.D., passed away on March 24, 2018. He was 87 years old. His contributions while at the NHLBI to the field of cardiovascular and pulmonary research fall nothing short of extraordinary, and include advancements in the development of artificial organs, and the pathophysiology of acute lung injury. Over the course of his career he was actively involved in the innovation and development of new dialysis machines, cuffless endotracheal tubes, and devices to prop open right-sided heart valves, thereby preventing left heart distention during percutaneous cardiopulmonary bypass. He designed special low-resistance endotracheal tubes to limit the necessary ventilatory pressure, in addition to endotracheal tubes that would help to limit bacterial colonization and methods for preventing ventilator associated pneumonias.

Ebola Virus: Lessons from a Unique Survivor

Reblogged from The NIH Director's Blog.

Ebola virus (green) is shown on cell surface

There are new reports of an outbreak of Ebola virus disease in the Democratic Republic of Congo. This news comes just two years after international control efforts eventually contained an Ebola outbreak in West Africa, though before control was achieved, more than 11,000 people died—the largest known Ebola outbreak in human history. Many questions remain about why some people die from Ebola and others survive. Now, some answers are beginning to emerge thanks to a new detailed analysis of the immune responses of a unique Ebola survivor, a 34-year-old American health-care worker who was critically ill and cared for at the NIH Special Clinical Studies Unit in 2015.
