An absence seizure, often called a petit mal seizure, might manifest as blank gazing for a few seconds or fast blinking (Center for Disease Control and Prevention, 2020). When aberrant electric activity develops in both the left and right hemispheres of the brain at the same time, it is considered to be a generalized seizure (grand mal seizure). In the midst of an absence seizure, a person may appear to be daydreaming because of their abrupt onset of staring spells, during which they may cease all movement and stare in a single direction. After around 15 seconds (some sources suggest ... Read More

According to their main purpose, plant tissues are divided into − Meristematic (forming) tissues − ensure the growth of plants; Permanent tissues − perform all other functions. Meristematic cells divide, forming new cells that increase in size and differentiate, forming all plant tissues and organs. According to their origin, meristematic tissues are divided into primary and secondary. Primary meristematic tissues − originate from the seed germ (apical meristems, pericycle); Secondary meristematic tissues − originate later in the life of the plant, most often from dedifferentiated parenchyma cells, which regain the ability to divide (cambium, phylogeny). According ... Read More

The human body's normal immune response involves the production of antibodies against viruses like SARS-Cov-2, the causative agent of COVID-19. The antibodies target the virus, attacking it and ultimately killing it. Simply put, that is immunology 101. Antibodies are just big molecules of protein that defend the body from invaders. Antibodies, sometimes called immunoglobulins, are proteins made by the immune system to fight infection. They help defend us from outside substances including germs, poisons, and viruses. Because our systems produce unique antibodies to combat various antigens, antibodies may be detected by a serology test. Unlike antibodies against other viruses ... Read More

Testing has use beyond only establishing whether or not a person has a virus. After a virus has been identified, its severity must be assessed to decide whether or not hospitalisation is necessary. Diagnostic tests and antibody tests are two types of testing. Molecular testing and antigen tests are two subsets of diagnostic procedures. Therefore, PCR tests are classified as a type of molecular test that looks for viral DNA. Blood antibody testing are one method of monitoring antibody levels. What is Antibody Test? Immunoglobulins, also known as gamma globulin proteins, are the building blocks of antibodies. Vertebrate blood and ... Read More

Immunoassays are a common type of bioanalysis because they utilise an antibody or an antigen to detect the presence of a target molecule in a biological sample. It is a sensitive biochemical assay for determining analyte presence or concentration. It is still a vital resource for doctors to use when dealing with infectious illnesses. Antibodies are used in these tests as an analytical reagent. The immunoassay was developed by Berson and Yalow in 1959; in 1977, they were awarded the Nobel Prize in Medicine for their pioneering work on the radioimmunoassay technology. In the years following, immunoassays saw significant development. ... Read More
