Lumone is the generic name applied to Enteric peptides secreted by the intestinal tract, especially the stomach and duodenal region to stimulate the secretion of gastrointestinal hormones (GI hormones) and Insulin. These are potential luminal factors (traveling the luminal route of intestine) that have clinical significance in connection with diabetes. Two important luminones are Incretin and Apelin.

Phonotaxis is the movement of animals in response to sound vibrations especially the sound vibrations in the ultrasound range. Even though human ear cannot sense ultrasound, many animal species can produce and hear ultrasound. They respond to certain frequencies of sound and show movements which may be Positive Phonotaxis or Negative Phonotaxis. Positive Phonotaxis refers to the movement of animals towards the source of sound waves of particular frequencies and Negative Phonotaxis away from the sound.

Digital Microscopy is the advanced technology that uses a CCD camera to output the image into a computer monitor. The major difference between the digital microscope and the conventional optical microscope is that, the image cannot be viewed directly through the eye piece lens.Image is output to a computer to view it on the screen . Low priced digital microscope and costly one are available to use in conjunction with a computer.

Fluorescence microscopy is a rapid expanding technique, both in the medical and biological sciences. The technique has made it possible to identify cells and cellular components with a high degree of specificity. The absorption and subsequent re-radiation of light by organic and inorganic specimens is typically the result of well-established physical phenomena described as being either fluorescence or phosphorescence. Certain antibodies and disease conditions or impurities in inorganic material can be studied with the fluorescence microscopy.

Cyclic AMP or Cyclic Adenosine Monophosphate is the second messenger important in many biological actions at the cellular level. It is the chemical messenger is generated in the cell membrane from Adenosine triphosphate or ATP in response to a signal from the first messenger (Hormone). cAMP is used for intracellular signal transduction in many organisms conveying the cAMP dependent pathway.

An Uninterrupted Power Supply is essentially a back-up battery to power electronic gadgets like Computer in the event of a power failure. If it happens, the Gadget will draw power from the UPS and will run the load for a prescribed time depending on the capacity of the battery. The change over time from the mains to battery power is less than 5 milli seconds so that the computer will not shut down. This is essential to protect the data in the computer.

The excitation of surface Plasmons by light is known as a Surface Plasmon Resonance or SPR. This is observed in nanometer-sized metallic structures. Surface Plasmons, are surface electromagnetic waves that propagate in a direction parallel to the metal or dielectric interface .This phenomenon is the basis of many standard tools for measuring adsorption of material onto planar metal (typically gold and silver) surfaces or onto the surface of metal nano particles.
