Myelodysplastic syndromes – causes, symptoms, diagnosis, treatment, pathology

Myelodysplastic syndromes, or MDS, are a group of rare blood disorders associated with faulty development of blood cells in the bone marrow. MDS can affect individuals of all ages, but it’s more common after the age of 60. Blood cells develop from hematopoietic stem cells, through a process called hematopoiesis. This involves a number of divisions, and eventually, […]

Why Stimulants Help ADHD

[♪ INTRO ] Odds are, you’ve heard of Ritalin or Adderall. They’re both members of the class of drugs called stimulants, and they’re often prescribed to treat attention deficit hyperactivity disorder, better known as ADHD. But stimulants and hyperactivity seem like a weird match. If someone can’t sit still, why would you give them more energy? Like with […]

Myelofibrosis – causes, symptoms, diagnosis, treatment, pathology

Myelofibrosis is a disease in which the bone marrow gets replaced by connective tissue in a process called fibrosis. Since the bone marrow’s main role is to produce erythrocytes, or red blood cells; leukocytes, or white blood cells; and thrombocytes, or platelets, the process of fibrosis interferes with production of these cell types. Now, many cells in the […]

A “living drug” that could change the way we treat cancer | Carl June

So this is the first time I’ve told this story in public, the personal aspects of it. Yogi Berra was a world-famous baseball player who said, “If you come to a fork in the road, take it.” Researchers had been, for more than a century, studying the immune system as a way to fight cancer, and cancer vaccines […]

Bullous pemphigoid – causes, symptoms, diagnosis, treatment, pathology

Bullous pemphigoid is an autoimmune skin disease that causes the skin to form bullae or blisters. Now, the skin is divided into three layers–the epidermis, dermis, and hypodermis. The epidermis forms the thin outermost layer of skin. Underneath, is the thicker dermis layer, and finally, there’s the hypodermis that anchors the skin to the underlying muscle. The epidermis […]

2016 Research Highlights from Johns Hopkins Medicine

At Johns Hopkins Medicine, scientific discovery is the engine that drives patient care and cures. Here are five new science highlights from 2016. These tiny lab grown brain structures could help us defeat the Zika virus. Researchers grew the sophisticated mini-brains out of human stem cells so that they could study Zika’s effect on a developing brain. By […]

The End of Antibiotics and the Future of Fighting Infections

Thank you all for coming. Tonight we’re going to talk about a very serious subject. Um, the situation that we face with antibiotic resistant bacteria. Antibiotics were once the silver bullet that seemed to be able to cure just about everything. Now we look at 23,000 antibiotic resistant bacterial infections every year. So let me introduce you to […]

Chronic Leukemia – causes, symptoms, diagnosis, treatment, pathology

With chronic leukemia, “leuk” refers to white blood cells, and “emia” refers to the blood; so in chronic leukemia there are lots of partially developed white blood cells in the blood over a long period of time. These partially developed white blood cells interfere with the development and function of healthy white blood cells, platelets, and red blood […]
