What Is The Normal Red Blood Cells In Urine – An interdisciplinary and international team of researchers, including Northwestern engineering professor Petia Vlahovska, discovered that healthy Red Blood Cells aggregate into a crystalline form, while pathological red blood cells undergo disintegration.
The findings raise the possibility of a new diagnostic tool to detect blood pathologies in diseases such as sickle cell anemia, a disease that the World Health Organization has long identified as a major global health problem.

“In diseases such as sickle cell anemia, red blood cells become rigid and do not form ‘crystals’, so the order can distinguish between healthy and diseased red blood cells and lead to a diagnostic tool to identify cardiovascular pathologies,” said Vlahovska. , a specialist. associate professor of engineering sciences and applied mathematics at Northwestern’s McCormick School of Engineering and Applied Science.

The study, titled “Blood Crystals: Extraordinary Red Blood Cell Arrangement Under Boundary Wall Flow,” was published June 28 in Review Letters. Led by Chauqi Misbah of Grenoble Alpes University and CNRS in France, the paper’s co-authors were researchers. from France, Germany and Holland except Vlahovska who has been working with Misbah since 2007.
Through experiments and simulations, the researchers tested the common hypothesis of blood circulation. The six-member team found that a healthy red blood cell is very soft and flexible, properties that help it form an orderly flow. When the red blood cells harden in diseases such as sickle cell anemia, this procedure is stopped.
“Red blood cells must always move as blood flows through the body’s network of blood vessels, and we have discovered a new structure for the normal shape of red blood cells, where they are chain-like,” Vlahovska said.
Understanding the red blood cell aggregates under flow is important for unraveling many blood and cardiovascular pathologies, which are the leading cause of death in the world. The research team’s findings open up a potential method for identifying healthy and diseased red blood cells, which could be useful for diagnosis and treatment development.

In addition to advancing knowledge about blood circulation, Vlahovska said the research team’s work also contributes to the broader field of self-organization research in out-of-equilibrium, active systems.
“Living systems exist out of equilibrium, and life is order that emerges from ‘disturbance’,” he said. “One of the big challenges is to understand what we can eventually mimic – how individual units like cells form into structures like tissues. The phenomenon we discovered is not limited to red blood cells, but is truly universal. and one thing is that it can be implemented in other synthetic systems.

A red blood cell is a blood cell that helps carry oxygen to the organs for use by the body’s cells. In some red blood cell diseases, changes in the size of red blood cells can occur, making them smaller or larger than normal.
The main function of red blood cells is to transport hemoglobin, which is the substance that carries oxygen from the lungs for exchange with body tissues. In addition, red blood cells contain large amounts of carbonic anhydrase, an enzyme that catalyzes a faster reaction between CO2 and water to produce carbonic acid (H2CO3). From there, it can convert large amounts of CO2 from the tissues to HCO3- to be transported back to the lungs, converted back to CO2 in the pulmonary capillaries, and exhaled into the air as a waste product of the body. .
Sickle Cell Anemia–causes Symptoms Diagnosis Treatment–prognosis
Microscopically, erythrocytes were found to be normal, nucleated, and rectangular, with an average diameter of 7.8 micrometers and a thickness of approximately 2.5 micrometers at their thickest point. in the central position is about 1 micrometer or even smaller. The average volume of erythrocytes is about 90 to 95 µm3.
The shape of a normal red blood cell can change dramatically as it passes through small capillaries. Red blood cells have a large amount of membrane for their internal contents, so this deformation does not unnecessarily stretch the membrane and rupture the cell.
Red blood cells can undergo many different diseases that change the shape and size of red blood cells. Here are some red blood cell diseases that cause changes in the size of red blood cells, including:
2.1. Megaloblastic anemia Megaloblastic anemia is an anemia in which the red blood cells are larger than normal. The causes of megaloblastic disease are:
Sickle Cell Disease Histology
Vitamin B12 deficiency: The most common cause of B12 deficiency is pernicious anemia due to decreased secretion of endogenous factors (usually secondary to autoantibodies). . Other common causes are malabsorption due to gastritis or tapeworm infection, poor diet. Vitamin B12 deficiency Folate deficiency: Common causes of folate deficiency include celiac disease and alcoholism. Manifestations of megaloblastic anemia:
Manifestations of anemia such as fatigue, pale skin and mucous membranes… are often silent, not obvious. Gastrointestinal manifestations may include diarrhea, mucositis, and anorexia. Blood tests: Usually, there are signs of anemia, such as the number of red blood cells, a decrease in hemoglobin, accompanied by an MCV (red blood cell volume) of more than 100 fl, RWD (red blood cell distribution range). In blood products, red blood cells are large, oval and irregular. To determine the cause of the disease, try more vitamin B12. 2.2. Microcytosis Microcytic anemia is defined as anemia in which the number of red blood cells is lower than normal. Some possible reasons for this are:
Iron deficiency: Iron is the substance that makes hemoglobin, so when there is a lack of iron in the body, red blood cells contain less hemoglobin and their size is reduced. . Possible causes of iron deficiency include chronic blood loss, lack of supply, increased demand… Thalassemia Hemolytic anemia: This is an inherited disorder that affects the total globin chain of hemoglobin. Lead poisoning: May occur from frequent exposure to sources of lead. Anemia of red blood cells: This is due to congenital or acquired causes that affect the production of bone marrow. Chronic inflammation: Also causes cells to store more iron than normal. Lack of blood supply in the body, which can be observed in cancer, rheumatoid arthritis …
Fatigue, dizziness, blue or yellow skin. Heart palpitations or palpitations. Mucous membranes, fragile nails. Shortness of breath, rapid breathing. Laboratory tests: Signs of anemia such as a normal or sometimes increased number of red blood cells, a decrease in hemoglobin, with MCV (red blood cell volume) less than 80 fl, often with MCH (average level of hemoglobin) in red cells. ) less than 28pg/l, RWD (red cell distribution range) is usually normal or elevated. Tests for its causes such as serum iron, ferritin (storage iron), hemoglobin electrophoresis if thalassemia is suspected. 2.3. Anemia of normal red blood cell size Anemia of normal red blood cell size is anemia in which the size of red blood cells is normal. It is usually seen in severe blood loss due to trauma or hemorrhagic disease.
Sickle Cell Disease (scd): Types, Symptoms & Causes
Manifestations of this anemia are often similar to those of chronic anemia, but more pronounced. Accompanying laboratory tests showed decreased red cell count and hemoglobin, but normal MCV and MCH.
Changes in the normal size of red blood cells are observed in many different erythropoiesis. Adequate nutrition, especially during periods of increased demand such as pregnancy, injury, infection… is a measure to prevent anemia.
