A megaspore mother cell is a diploid cell in plants in which meiosis will occur, which will produce four haploid megaspores. At least one of the spores develop into haploid female gametophytes.
Primary endosperm nucleus is the nucleus formed by the fusion of two polar nuclei in the embryo sac of a seed plant prior to fertilization.
An intrauterine device (IUD or IUCD or ICD) is a small, often T-shaped birth control device that is inserted into a woman’s uterus to prevent pregnancy. IUDs are one form of long-acting reversible birth control (LARC). IUDs are either copper or hormonal.
Medical Termination of pregnancy or Abortion by medical methods
Sexually Transmitted Diseases are the infections that are transmitted during vaginal, anal, and oral sex, and is caused by bacteria, viruses or parasites.
ET & IVF
Embryo transfer is the process of assisted reproduction or in vitro fertilization (IVF), in which embryos are placed into the uterus of a female with the intent to establish a pregnancy.
Assisted reproductive technology are medical procedures used primarily to address infertility. It includes procedures such as in vitro fertilization.
Pelvic inflammatory disease (PID) is an infection of the reproductive organs in women. It’s marked by pain in the abdomen, especially during urination or sex.
Zygote intrafallopian transfer (ZIFT) is an infertility treatment used when a blockage in the fallopian tubes prevents the normal binding of sperm to the egg. Egg cells are removed from a woman’s ovaries, and in vitro fertilised. The resulting zygote is placed into the fallopian tube by the use of laparoscopy.
Artificial insemination is the deliberate introduction of sperm into a female’s cervix or uterine cavity for the purpose of achieving a pregnancy through IVF by means other than sexual intercourse.
Intrauterine insemination (IUI) is a fertility treatment that involves placing sperm inside a woman’s uterus to facilitate fertilization. The goal of IUI is to increase the number of sperm that reach the fallopian tubes and subsequently increase the chance of fertilization.
IUT or Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary.
ICZN is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated like animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature.
Embryo Transfer (ET) is an effective method of increasing the reproduction rate of individuals or groups of animals. This is an introduction to the Multiple Ovulation and Embryo Transfer (MOET) procedure. All-female animals are capable of producing far more eggs than they ever need over their lifetime.
Single Cell Protein are edible unicellular microorganisms that are derived from a culture of single-celled organisms, which is used especially as a food supplement.
Lactic acid bacteria (LAB) are an order of gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod-shaped (bacilli) or spherical (cocci) bacteria that share common metabolic and physiological characteristics.
Sewage Treatment Plants or Wastewater Treatment Plants are used to treat the sewage or waste coming from various houses, factories, wtc.
Biochemical Oxygen Demand is the amount of dissolved oxygen needed by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
MALT is a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, oral passage, nasopharyngeal tract, thyroid, breast, lung, salivary glands, eye, and skin.
Cell-mediated immunity is an immune response that does not involve antibodies, but rather involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.
HIV & AIDS
Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV).
The National AIDS Control Organisation (NACO), established in 1992 is a division of India’s Ministry of Health and Family Welfare that provides leadership to HIV/AIDS control programme in India through 35 HIV/AIDS Prevention and Control Societies, and is “the nodal organisation for formulation of policy and implementation of programs for prevention and control of HIV/AIDS in India”.
Computed tomography (CT) is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is also called computerized tomography and computerized axial tomography (CAT).
Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease.
The enzyme-linked immunosorbent assay is a commonly used analytical biochemistry assay, first described by Weiland in 1978. The assay uses a solid-phase enzyme immunoassay to detect the presence of a ligand in a liquid sample using antibodies directed against the protein to be measured.
They are also called polymorphonuclear leukocytes or polymorphonuclear neutrophils (PMN, PML, or PMNL) because of the varying shapes of the nucleus, which is usually lobed into three segments. This distinguishes them from the mononuclear agranulocytes.
Humoral immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides. Humoral immunity is so named because it involves substances found in the humors or body fluids. It contrasts with cell-mediated immunity. Its aspects involving antibodies are often called antibody-mediated immunity.
Intracytoplasmic sperm injection is an IVF procedure in which a single sperm cell is injected directly into the cytoplasm of an egg. This technique is used in order to prepare the gametes for obtaining the embryos that may be transferred to a maternal uterus.
Reproductive tract infections (RTIs) are caused by organisms normally present in the reproductive tract, or introduced from the outside during sexual contact or medical procedures. These different but overlapping categories of RTI are called endogenous, sexually transmitted infections (STIs) and iatrogenic, reflecting how they are acquired and spread.
The International Code of Botanical Nomenclature (ICBN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants.
PPLO is a mycoplasma that is resistant to antibiotics and causes a kind of pneumonia in humans.
