describe how acute leukemias can be differentiated through the use of phenotyping cells by using flow cytometry technology. include the flow cytometry methodology, instrument parts and how the instrument makes this differentiation possible.
Answers
Under a microscope, certain poisons can be detected on the leukemic cell's surface. These are typically antigens or markers found on the surface of white blood cells.
The clusters of differentiation (CD) markers are the name given to these antigens. Such indicators' existence or absence aids in the leukemia diagnosis.
The antigen patterns or molecules that a normal cell expresses on its surface define its maturity or type. To identify them, these markers have unique CD numbers allocated to them.
As a result of the flow cytometry, a diagnosis can be made by comparing the discovered CD counts to regular and abnormal cells. In leukemia, the cell surfaces of CD5, CD19, CD23, CD20, Kappa, and Lambda markers are typically present, whereas prognostic markers CD38 and D49d are also present.
A suspension of monodisperse single, unclumped cells is absorbed by flow cytometers, which then run the cells one at a time (single file) via a fluorescent light ray where every cell passes through, before being counted, sorted, and then described.
The fluidics, optics, and electronics are the three primary parts of a flow cytometer.
What is flow cytometer?
To recognize and measure the physical and chemical characteristics of a population of cells or particles, a method known as flow cytometry is used. A fluid-suspended sample containing cells or other particles is delivered into the flow cytometer apparatus during this technique.

what are characteristics of the conducting passages of the bronchial tree as air moves from the primary bronchi to the alveolar ducts?
Answers
The width of the conducting channels is smaller and there is less cartilage in the bronchioles.
Bronchioles- Smaller and smaller passages, known as bronchioles, branch out from the major airways (bronchi), leading to air sacs (alveoli).
Alveoli- Small air sacs near the bronchioles' ends (tiny branches of air tubes in the lungs). While breathing in and out, oxygen and carbon dioxide are exchanged between the blood and alveoli in the lungs.
Cartilage- The body's supporting connective tissue, cartilage, is a non-vascular form that may be found everywhere. Due to its avascularity and less ordered microarchitecture than bone, cartilage is a loose connective tissue that varies from bone in a number of ways.

Hypothesis:
PLEASE FILL IN THE BLANK ABOVE!!
Answers
The independent variable is the size of the coin. The number of water drops is the dependent variable. control is a coin with no water. the constant is the same dropper / same water.
The cause is the independent variable. Its value is unaffected by the other study variables. The effect is the dependent variable. Changes in the independent variable affect its value.
By presenting both variables in the statement below in a way that makes sense, you may quickly determine which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV). "The DV changes as a result of the IV. There is no chance that DV might alter IV in any way.
The variable that changes and on which the dependent variable depends is known as the independent variable. Consequently, the number of water drops the coin might hold depends on its size. The size of the coin is therefore the independent variable.

altered cortical glutamatergic and gabaergic signal transmission with glial involvement in depression
Answers
Altered cortical glutamatergic and GABAergic signal transmission, along with glial involvement, occurs in depression.
Glutamate and GABA imbalances affect neural activity, while glial cells, particularly astrocytes and microglia, contribute to neuroinflammation and synaptic dysfunction. These disruptions impact mood regulation and cognitive processes, leading to depressive symptoms.
The glutamatergic system's hyperactivity and reduced GABAergic inhibition result in increased excitatory signaling and impaired synaptic plasticity. Glial cells play a vital role in regulating neurotransmitter homeostasis and inflammatory responses, potentially exacerbating the dysfunction. Understanding these complex interactions could aid in developing novel therapeutic interventions for depression targeting glutamate, GABA, and glial function.

It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery.

Which substances protect against oxidative stress and the resultant cell damage?.
Answers
The substances protect against oxidative stress and the resultant cell damage is oxidative products B-antioxidant carotene's .
By directly scavenging ROS and/or by preventing cell growth as a result of protein phosphorylation, antioxidants can reduce oxidative stress-induced carcinogenesis. Due to the possibility of genetic damage caused by oxidative products, B-antioxidant carotene's properties may offer protection against cancer.A medical revolution that promises a new era of health and illness treatment is being brought about by the recent expansion of biology's understanding of free radicals and reactive oxygen species (ROS). It is odd that oxygen, a substance required for life, can harm the human body in some circumstances. The production and activity of several chemical molecules known as ROS, which have a propensity to give oxygen to other substances, is the primary cause of the majority of the potentially detrimental effects of oxygen.

Which is a condition that accompanies left-sided heart failure and is characterized by noninfectious fluid build-up in the alveoli and lung tissues
Answers
The condition that accompanies left-sided heart failure and is characterized by noninfectious fluid build-up in the alveoli and lung tissues is called pulmonary edema. It occurs when the left ventricle of the heart is unable to pump the blood effectively to the rest of the body, causing the blood to back up into the lungs, thereby increasing the pressure in the blood vessels of the lungs.
This increased pressure causes fluid to leak out of the blood vessels and into the alveoli and lung tissues, making it difficult for the person to breathe. Pulmonary edema is a serious condition that requires immediate medical attention as it can lead to respiratory failure, cardiac arrest, and even death if left untreated.
The symptoms of pulmonary edema include shortness of breath, rapid breathing, wheezing, coughing up pink, frothy sputum, chest pain, and anxiety. Treatment for pulmonary edema usually involves medications that help remove the excess fluid from the lungs and improve the heart's function. Diuretics are commonly prescribed to remove excess fluid from the body, including the lungs.
Oxygen therapy may also be given to improve breathing, and medications such as nitroglycerin and morphine may be used to help reduce the workload on the heart and improve blood flow. In severe cases, mechanical ventilation or extracorporeal membrane oxygenation (ECMO) may be necessary to support breathing and circulation. In conclusion, pulmonary edema is a condition that accompanies left-sided heart failure and is characterized by noninfectious fluid build-up in the alveoli and lung tissues.

We can see here that identifying the stage in the cycle the hormone levels are at their highest and most active, we have:
Box 1: Luteinizing hormone levels high.
Box 2: Progesterone levels high
Box 3: Estrogen levels consistently rise.
What is hormone?A hormone is a chemical substance produced by the endocrine glands in the body.
Luteinizing hormone (LH) levels rise sharply in the middle of the menstrual cycle, which is called the ovulatory phase. This surge of LH triggers ovulation, the release of the mature oocyte from the ovary.
Progesterone levels rise after ovulation and peak in the luteal phase. Progesterone prepares the uterus for pregnancy by thickening the lining of the uterus. If pregnancy does not occur, progesterone levels drop and the menstrual cycle begins again.
Estrogen levels rise throughout the follicular phase, which is the first half of the menstrual cycle. Estrogen levels peak just before ovulation.
