Hemolysis

to be a type of severe preeclampsia during pregnancy. Preeclampsia is a disorder of pregnancy that causes high blood pressure and protein in the urine. It develops after the 20th week of pregnancy. The name HELLP stands for: H – hemolytic anemia, hemolysis (destruction of blood cells). EL – elevated liver enzymes (sign of liver damage). LP – low platelet count (blood cells that help stop bleeding). HELLP syndrome often occurs without warning and can be difficult to recognize. In most cases,…

One important allele is the S beta chain responsible for sickle cell anemia, it differs in one amino acid from a normal beta-chain. At the beta gene locus, two possible alleles have two base sequences A = normal beta-chain and S = sickle-cell beta chain. Sickle cell anemia is due to abnormality of hemoglobin, a (protein carrying oxygen to the tissues). “Anemia is a decrease in RBCs; or hemoglobin; or ability to carry oxygen. Hemoglobin S (allele HbS) causes Sickle Cell Anemia, without…

Sickle Cell Anemia is a trait or disorder that is characterized by abnormal hemoglobin which causes red blood cells to become crescentic or sickle shaped, erythrocytes and by speeding up hemolysis, due to substitution of a single amino acid. Low oxygen tension causes polymerization of the abnormal beta chains which changes the shape of the red blood cells to the sickle form. Sickle cells are fragile and they break apart easily they die leaving you with a poor amount of red blood cells. The red…

Discussion The various test that were completed had supporting evidence that deduced the identity of the unknown microorganism. A gram stain was performed on the bacterium and a purple color was seen under the microscope. The purple hue that was acquired by the unknown microorganism indicated that the organism had a thick peptidoglycan layer meaning that the bacterium was gram positive. Looking under the microscope helped to identify the cellular arrangement of the bacterium which was sphere…

Materials and Methods Materials used in experiment 1.1A: Nutrient agar plate Materials used in experiment 1.1B: Nutrient agar plate, Sterile cotton swab In experiment 1.1B a nutrient agar plate was opened and left in an arbitrary spot in the laboratory and left untouched for three hours, at the end of the lab it was collected and incubated at . In part B a swab/swab rinse method was preformed in order to inoculate the nutrient agar plate. A sterile cotton swab was taken out of its packaging, an…

1) What is a PCV? What does PCV stand for? What is another name for PCV? Describe the procedure for obtaining a PCV. o PCV stands for packed cell volume. o Another name for a PCV is hematocrit. o A PCV is the measurement of the ratio of packed red cells in a known volume of whole blood sample. o The procedure is to take blood from your patient and put it into a purple top tube, which has the anticoagulant EDTA in it. • Next you need to fill 2 micro hematocrit tubes with the blood about ¾ a…

To begin, a streak was performed on two TSA plates and a blood agar plate using the three-sector streak technique from the unknown culture tube to isolate the two unknown bacterial colonies. The plates were then incubated for 12 hours at 37 ̊C. The blood agar plate was used to create a greater contrast in color to help distinguish between bacterial colonies by size and color. Two distinct colonies could be seen growing on the blood agar plate shown in figure 1. The smaller, opaque colored…

blood cell is in a hyper-osmotic solution, or a solution with high salt concentrations, it will crenate. Likewise, if a red blood cell is in a solution with low salt and concentrations than the cells intra-cellular environment, the cell will undergo hemolysis. The dependent variable of the experiment is the cells volume and overall cell behavior. The independent variable is the created and known solution of different salt concentrations used to put the different red blood cells. The final cell…

CHAPTER I INTRODUCTION Background and Significance Sickle cell disease (SCD) is an inherited red blood cell disorder that is present at birth and is often more prevalent amongst African Americans.1 In order to inherit SCD, a person must inherit two abnormal hemoglobin genes, one from each parent. Hemoglobin is a protein found in red blood cells that is responsible for absorbing oxygen in the lungs and transporting it throughout the body.13 Proteins typically have four levels of structure:…

1a) Symptoms: I) Slightly delayed speech abilities Children begin their speech and language development at birth, when an infant develops normally with no trace of lead contamination in their system they are able to recognize many of the sounds at the age of one. However, infants who are exposed to lead have issues when it comes to brain development in their Broca’s area which allows them to read and understand spoken language but shows difficulty in speaking and writing. The reason behind this…
