Researchers at Northwestern Medicine and Brigham and Women’s Hospital say they’ve discovered a root cause of lupus, a disease that affects hundreds of thousands of people in the U.S ...
An autoimmune disease is a condition that results from an anomalous response of the adaptive immune system, wherein it mistakenly targets and attacks healthy, functioning parts of the body as if they were foreign organisms. [1] It is estimated that there are more than 80 recognized autoimmune diseases, with recent scientific evidence suggesting ...
Radiation-induced cancer. Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing ...
Embryonic stem cells make up a significant proportion of a developing embryo, while adult stem cells exist as minor populations within a mature individual (e.g. in every 1,000 cells of the bone marrow, only one will be a usable stem cell). Thus, embryonic stem cells are likely to be easier to isolate and grow ex vivo than adult stem cells. [36]
Sickle cell disease ( SCD ), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [ 2] The most common type is known as sickle cell anemia. [ 2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [ 2] This leads to a rigid, sickle -like shape under ...
Aging is associated with blood flow changes in the brain. These changes may be linked to an increased risk of neurodegenerative conditions. A new mouse study maps how these changes vary throughout ...
Previous ACS research had shown that rates of 11 cancers, including pancreatic, colorectal, kidney, uterine and testicular cancer, had been increasing among young adults. The new study added eight ...
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
