Found Hormones 40 times.

Displaying results 1 to 10.

1. Adrenal gland
This gland is found above each kidney, and it made up of an outer wall ( cortex ) that secretes important steroid hormones and an inner portion (medulla) that produces adrenaline (epinephrine) and noradrenaline (norepinephrine) .

2. Adrenocorticotrophic hormone (ACTH)
A peptide hormone produced by the anterior pituitary gland . It stimulates the adrenal cortex to secrete glucocorticoid hormones, which help cells synthesize glucose , catabolize proteins , mobilize free fatty acid s, and inhibit inflammation in allergic responses.

3. Adrenocorticotropic hormone (ACTH)
A hormone produced by the anterior pituitary that stimulates the adrenal cortex to release several hormones including cortisol.

4. Anther culture
A plant culturing technique in which immature pollen is made to divide and grow into tissue (either callus or embryonic tissue) in either a liquid medium or on solid media. Pollen-containing anther s are removed from a flower and put in a culture medium; some microspheres survive and develop into tissue. If embryonic tissue develops, it's put in a medium favorable for shoot and root development; if it's callus tissue, it's put in a solution of hormones that will spur it to differentiate and develop shoot and root tissue.

5. Auxins
A group of hormones involved in controlling plant growth and other functions; once thought responsible for phototropism by causing the cells on the shaded side of a plant to elongate, thereby causing the plant to bend toward the light.

6. Bioaffinity sensor
A sensor that uses immobilized hormone receptor s or antibodies to detect hormones or antigen s.

7. Birth control (contraception, family planning)
In general, birth control or contraception is anything that prevents a woman from becoming pregnant. The most basic and cheapest form of contraception is abstinence (not engaging in sexual intercourse at all). However, abstaining from sex can cause great stress and frustration in some, since the human sex drive can be quite powerful. A variation on abstinence is fertility awareness (also known as "natural family planning"). This method involves a couple avoiding intercourse during the times that the woman is most likely to be fertile. This method requires that the woman be very aware of her own body and her reproductive cycle; some estimate that this method has a 70%-98% rate of success, depending on the regularity of the woman's cycle and the specific monitoring technique used. Signs that a woman has ovulated (and is therefore fertile) include a sudden change in basal body temperature, changes in vaginal mucus, or a combination of the two. A woman is least likely to be fertile during her menstrual period and for a few days thereafter. Barrier methods of birth control work by preventing sperm from reaching the egg. Barrier methods work best in conjunction with spermicides (creams or jellies that contain chemicals that kill sperm and sometimes disease-causing microorganisms). Because barrier methods also prevent the exchange of body fluids to varying degrees, they are also useful in preventing the transmission of venereal disease s. Barrier methods include: * condom s * female condom s * diaphragm s * cervical cap s * contraceptive sponges Other birth control methods work by altering a woman's hormones so as to render her infertile (male hormonal birth control is being researched). Hormonal methods include: * Depo Provera * birth control pills * Norplant * "morning after" pills Other women may use intrauterine devices (IUDs), which work mainly by preventing the fertilized egg from implanting in the wall of the uterus. Other women use abortion (surgery to remove or drugs to induce the expulsion of an embryo or fetus) as a last-ditch effort at birth control. If a couple wants no children at all, they may undergo surgery to render themselves sterile. In women, this procedure is generally a tubal ligation (cutting or blocking the Fallopian tubes, which carry the eggs from the ovaries). In males it is a vasectomy (cutting or blocking the tubes that carry sperm from the testis). These procedures can sometimes be reversed.

8. Cholesterol
Cholesterol is absorbed from the intestine and contained in chylomicron which brings the cholestrol to the liver. Some cholesterol is synthesized by the liver. Cholesterol is the precursor of steroid hormones and constituent of cell membranes. Some cholesterol is excreted in the bile. The rest of cholesterol is carried in blood by lipoproteins. Lipoproteins in serum are classified according to their density. High-density lipoproteins (HDL), low-density lipoproteins (LDL), and very low density lipoproteins (VLDL). Each fraction contains cholesterol. It is the proportion of cholesterol in these fractions of lipoprotein that is associated with the risk of atherosclerotic heart disease (ASHD): the higher the level of LDL cholesterol, the greater the risk of ASHD, and the higher the level of HDL cholesterol, the lower the risk of ASHD. Lowering the serum cholesterol level in patients without cardiac disease do not reduce mortality rate. Lowering the cholesterol level in cardiac patients clearly reduces mortality. This reduction of risk is proportional to the reduction in LDL cholesterol and the increase in HDL cholesterol. (Normal ranges for serum cholesterol are 1.2 - 6.5 mmol/L)

9. Cortex
1) The outer part of an organ, e.g., the adrenal cortex, which produces several steroid hormones ; 2) in plants, the region of the stem or root between the epidermis and the vascular bundle(s) .

10. Cycle
A recurring sequence of events; e. g., the secretion of certain hormones at regular intervals.
