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.

for a lateromedial view of the tarsal joint of a horse, the cassette shoud be placed in which position?
On the medial surface to view of the tarsal joint of a horse.
Standard metatarsal series
Four views make up a typical metatarsal series: a plantarodorsal, lateral, and two obliques that are designed to profile the lateral and medial splint bones away from the shaft of the cannon bone. For orientation, it can be helpful to include small amounts of the tarsus above or the fetlock beneath, although combined tarsometatarsal or metatarsophalangeal exams typically result in subpar images due to geometric distortion brought on by decentering.
It is simple to distinguish between the medial and lateral aspects of the proximal metatarsus because the head of the lateral splint bone (fourth metatarsal) is almost twice as big as its medial counterpart (second metatarsal).
Another way to distinguish the lateral from the medial aspect of the metatarsus is by the partial articulation of the lateral splint with the overlaying fourth tarsal bone.
The little metatarsal bones' natural curvature, especially distally, usually causes the surrounding cannon bone to partially obscure them, mimicking a fractured splint.

hich of the following enhances phagocytosis of microbes by macrophages? i) the binding of antibodies to the surface of microbes ii) antibody-mediated opsonization of microbes iii) the release of cytokines by activated b cells
Phagocytosis of microbes by macrophages is enhanced by both the binding of antibodies to the surface of microbes & antibody-mediated opsonization of microbes.
Phagocytosis is the process through which larger-than-0.5 m-diameter particles, such as bacteria, foreign objects, and apoptotic cells, are taken up and excreted by cells.
Since phagocytosis occurs in a wide variety of cell types, it is crucial for maintaining tissue homeostasis.
However, only specialized cells called professional phagocytes are able to phagocytose with great efficiency.
Macrophages, neutrophils, monocytes, dendritic cells, and osteoclasts are a few of these specialized cells.

Explain about urine formation?Urine Formation
Kidney contains nephrons ,whose main function is excrete out unwanted substance from body , in the form of urine.Urine formation involves three major process i.e. , Glomerular filtration , Tubular reabsorption and Tubular secretion.Glomerular filtration -
It is the filtration process in which blood is filtered and the nitrogenous waste and water moves inside the glomerulus.It is a process of ultrafiltration that is carried out by the glomerulus and it's the first step in urine formation.Around 1100-1200 ml of blood is filtered by the kidneys per minute.Tubular reabsorption -
In this process, the molecules and ions gets reabsorbed into the circulatory system.Around 99% of the glomerular filtrate formed is reabsorbed by the renal tubules in the kidneys.Substances like glucose, amino acids, sodium ions, nitrogenous wastes, water, etc. are reabsorbed.Tubular secretion -
The secretion process in which , substances like hydrogen ions , creatinine and drugs are removed from the blood and collected in the duct.And the end product of this is the Urine.It is an important step in urine formation as it helps in maintaining ionic and osmotic balance in the body.Sodium ion, hydrogen ion, and ammonia are secreted into the filtrate by the tubular cells in the kidneys.To learn more about urine formation refer to:

the mechansim of stabilizing the gfr (glomerular filtration rate) based on the tendency of smooth muscle to contract when streched is known as . a. sympathetic control b. tubuloglomerular feedback c. renal autoregulation d. the renin-angiotensin-aldosterone mechanism e. the myogenic mechanism
There are two mechanisms by which this occurs. The first is called the myogenic mechanism. The second mechanism is called the tubuloglomerular feedback. So, option b and e are the correct answers.
Renal myogenic mechanisms are part of the autoregulatory mechanisms that maintain constant renal blood flow under various arterial pressures. Simultaneous autoregulation of glomerular pressure and filtration indicates regulation of preglomerular resistance.
Tubuloglomerular feedback is an adaptive mechanism that relates glomerular filtration rate to salinity in the tubular fluid of the macula compacta. A high proportion of [NaCl] and reabsorption at this site constricts afferent arterioles and reduces GFR.
In this mechanism, termed tubuloglomerular feedback (TGF), an increase in NaCl concentration in the macula densa constricts glomerular afferent arterioles, reducing single freon GFR. Along with myogenic responses, TGFs contribute significantly to renal autoregulation.

The function of the Hox genes is to specify positional identity in the embryo rather than the development of any specific structure. These genes are an evolutionary highly conserved gene family. These genes determine the anterior-posterior body axis in bilateral organisms and influence the developmental fate of cells. One copy of a gene can perform the original function, while other copies are available to take on new functions.
