MICROENCAPSULATION..APPLICATION TO REAL LIFE

MICROENCAPSULATION

The reasons for microencapsulation are countless. In some cases, the core must be isolated from its surroundings, as in isolating vitamins from the deteriorating effects of oxygen, retarding evaporation of a volatile core, improving the handling properties of a sticky material, or isolating a reactive core from chemical attack. In other cases, the objective is not to isolate the core completely but to control the rate at which it leaves the microcapsule, as in the controlled release of drugs or pesticides.

A vitamin is an organic compound required as a nutrient in tiny amounts by an organism. A compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Thus, the term is conditional both on the circumstances and the particular organism. For example, ascorbic acid functions as vitamin C for some animals but not others, and vitamins D and K are required in the human diet only in certain circumstances.

Every system in our body depends on intra-cellular trafficking, because anything that goes from the inside of a cell to the outside, or from outside to inside, uses this process," Segev said. "Malfunctioning of this pathway can cause a variety of human diseases.

DIABETES:

For example, problems in insulin secretion or presentation of insulin-receptors on the cell membrane result in diabetes.

Diabetes mellitus often referred to simply as diabetes is characterized by disordered metabolism and abnormally high blood sugar resulting from insufficient levels of the hormone insulin The characteristic symptoms are excessive urine production due to high blood glucose levels, excessive thirst and increased fluid intake attempting to compensate for increased urination, blurred vision due to high blood glucose effects on the eye's optics, unexplained weight loss, and lethargy. These symptoms are likely to be less apparent if the blood sugar is only mildly elevated.

CANCER:

Defects in growth factor secretion and presentation of their receptors on cells result in cancer.

Assuming that you eat right, train properly, and get enough sleep, there are only two factors limiting your growth; the amount of anabolic, tissue building, and catabolic, tissue destroying, hormones in your blood.

Training causes your muscles to process anabolic hormones. To promote the optimum level of growth, you must learn how long to train before resting and allowing your body to replace the anabolic hormones that have been used up. If you over train, all of the anabolic hormones will be used up and the catabolic hormones will start to dominate. If you under train, you will waste some of the natural anabolic hormones that your body produces.

BRAIN DEFECT:

Defects in neurotransmitter release or internalization result in brain disorders." The first step in this process involves freeing the neurotransmitter-containing vesicles from the bonds that hold them to the cytoskeleton. The vesicles are then free to travel to the active zones, where docking takes place. Docking is the process by which the vesicle and the pre-synaptic membrane line up in a position that will allow them to fuse easily. Fusion then takes place, in which the vesicle membrane and the pre-synaptic membrane connect to form a small opening, a pore, connecting the lumen of the vesicle with the synaptic cleft. This pore grows larger and larger until the vesicle membrane collapses into the pre-synaptic membrane and releases its contents into the synaptic cleft, a process called exocytosis.
