Sun and tanning bed exposure over a lifetime leads to actinic keratosis, also known as solar keratosis, the most prevalent premalignant skin disease. Inflammatory eczema often appears in infancy or early childhood and has a hereditary component. Rash is the most prevalent sign, followed by dryness, redness, and itching. It most frequently manifests itself on the extremities, but can also show up on the face, hands, neck, or even the backs of the knees. What is Actinic Keratosis? Actinic keratosis develops when epidermal keratinocytes undergo alterations. Causes and prevalence − Actinic keratosis is caused by being exposed to the ... Read More

When aberrant electrical impulses are sent between the two sides of the brain, it is called an absence seizure. When a person is suffering from dissociation, they become detached from or disengage from reality. What are Absence Seizures? Petit mal seizures (also known as absence seizures) manifest visually as looking blankly for a few seconds or rapid 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 ...

Loss of consciousness and blank gazing are the symptoms of absence seizures and complex partial seizures, respectively. Electroencephalogram (EEG) and magnetic resonance imaging (MRI) scans of the brain can confirm their diagnosis, and drugs can be used to treat both the conditions. Read this article to learn more about Absence Seizure and Complex Partial Seizure and how they are different from each other. What is Absence Seizure? Petit mal seizures (also known as absence seizures) manifest visually as looking blankly for a few seconds or rapid blinking (Center for Disease Control and Prevention, 2020). When aberrant electric activity develops in ... 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

The detection of antibodies in the blood is done with an antibody test. To collect a sample for further analysis, such as a nucleic acid or antibody test, a swab test can be performed. What is Antibody Test? Immunoglobulins, also known as gamma globulin proteins, are the building blocks of antibodies. Vertebrate blood and other bodily fluids include antibodies. They aid vertebrate immune systems in recognising and eliminating pathogens. This is why detecting antibodies in the blood is what an antibody test does. The human body naturally generates antibodies for self-defense, however vaccination may be used to artificially increase antibody ... 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

Actinic keratosis is the skin lesions that occur because of exposure to the sun directly for a longer duration. The risk of developing these is directly proportional to the amount and duration of sun exposure. These are more commonly seen in old age people, fair skin individuals, males, and in immunosuppressive patients. When the skin is exposed to UV radiation for a longer duration it causes various changes in the skin layer, altering the regular pathways of cell growth and causing the inflammation. Actinic keratosis is also called senile keratosis or solar keratosis. These are the most common skin disorders ... Read More
