Here we analyse how are red blood cells born and how they live and die in a brief overview of the whole process with special mention of the morphological aspects from bone marrow and spleen provided by transmission and scanning electron microscopy....
Cells need a way to adjust to the amount of oxygen they have, while still doing their important jobs."The committee said that the discoveries are vital for physiology and could exploit new strategies to fight anemia(贫血症), cancer and many other diseases.Kaelin was born in New York and ...
Cells: Every living being has living cells inside their bodies, and a human body has millions of them. Any change in the human body is attributed to the cells. Many cells die, and new cells are born as we are exposed to the environment. ...
As the smallest living units, cells are key to understanding disease—and yet so much about them remains unknown. We do not know, for example, how billions of biomolecules—like DNA, proteins, and lipids—come together to act as one cell. Nor do we know how our many types of cells inte...
It's been more than two years and we are still living in the shadow of Covid-19. There have been many pandemics through history, such as the Black Death, and our species has survived. Sam and Neil discuss how pandemics end, and teach you ...
A good place to investigate this question is in the shoot meristem, the growing tip of the plant, which supplies new cells to make leaves, flowers, and stems. Meristem cells constantly grow and divide. Their divisions are often not equal, producing cells of different sizes. Over time, these...
Research posits that normal stem cells mutate into CSCs under specific body environmental and/or genetic conditions. However, in the case of the liver, until recently, studies were yet to confirm the particular conditions and triggers for this conversion to CSCs, and whether these are environmental...
Sperm are cells that fertilize a female’s eggs as part of the human reproductive process. They must travel from a male’s testicles, where they’re made, to a female’sfallopian tubes, where eggs are found. But they can’t get there on their own. Instead, semen carries them. ...
CHUNG-SOOK (CONT’D) What are you going to do about it? What’s the plan, genius? She treats Ki-Tek like shit, but it doesn’t bother him. He rises with the most serene, enlightened smile, then plods over to the -- LIVING ROOM SLASH KITCHEN Where he removes a bag of white ...
Dr. Blobel is continuing his research to unravel the passage of signals between the cell's nucleus and cytoplasm. Learning how normal cells communicate through these signals will help scientists to understand what goes amiss in cancerous cells, and how brain cells are damaged by Alzheimer's ...
