Single cell organisms need hemoglobin to survive in an oxygen-free environment When green algae "can't breathe", they get rid of excess energy through the production of hydrogen. Biologists at the Ruhr-Universität Bochum have found out how the cells notice the absence of oxygen. For this, they need the messenger molecule nitric oxide and the protein hemoglobin, which is commonly known from red blood cells of humans. With colleagues at the UC Los Angeles, the Bochum team reported in the...

Efficient Hemoglobin Key To Fish Success

Brett Smith for redOrbit.com - Your Universe Online The primordial oceans in Earth´s early days were a much more inhospitable than they are today, and new research published in the journal Science suggests that fish developed a highly efficient hemoglobin-based system to deliver large amount of oxygen to their tissues. “Four hundred million years ago the oceans were not what they are today. They were low in oxygen, high in CO2 and acidic,” said study co-author Jodie...

Researchers at Whitehead Institute have identified a protein that is the target of glucocorticoids, the drugs that are used to increase red blood cell production in patients with certain types of anemia, including those resulting from trauma, sepsis, malaria, kidney dialysis, and chemotherapy. The discovery could spur development of drugs capable of increasing this protein's production without causing the severe side effects associated with glucocorticoids. "This research is medically...

Washington University in St. Louis [ Watch The Video Red Blood Cells Bifuracating in Capillary ] In an engineering breakthrough, a Washington University in St. Louis biomedical researcher has discovered a way to use light and color to measure oxygen in individual red blood cells in real time. The technology, developed by Lihong Wang, PhD, the Gene K. Beare Distinguished Professor of Biomedical Engineering, could eventually be used to determine how oxygen is delivered to normal and...

Researchers at Albert Einstein College of Medicine of Yeshiva University and the Icahn School of Medicine at Mount Sinai have found that macrophages — white blood cells that play a key role in the immune response — also help to both produce and eliminate the body's red blood cells (RBCs). The findings could lead to novel therapies for diseases or conditions in which the red blood cell production is thrown out of balance. The study, conducted in mice, is published today in the...

Transfusion of donated blood more than three weeks old results in impaired blood vessel function, a new study of hospital patients shows. Blood banks now consider six weeks to be the maximum permitted storage time of blood for use in transfusion, but recent studies have suggested transfusing blood stored for more than a few weeks has adverse effects in patients undergoing cardiac surgery or critical care. The new finding suggests a mechanism explaining why older blood might be...

Blood Shelf Life Shorter Than Previously Thought

Alan McStravick for redorbit.com — Your Universe Online Over the past five years, studies have been conducted exploring the efficacy of transfused blood in delivering oxygen throughout the body. More specifically, those studies focused on the breakdown of nitric acid contained in red blood cells. The deterioration of the nitric acid begins almost immediately after blood is drawn from a donor. Regardless of how much oxygen may be contained in a red blood cell, if there is an...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
