(The First Duty [TNG])

biofilter, transporter

A subsystem of the transporter designed to scan an incoming transporter beam prior to materialization, and remove potentially harmful disease and virus contamination.

The biofilter could be programmed against a wide range of disease organisms, but was only effective against organisms so programmed.

The biofilter was not only a very ingenious idea, but a very logical one in terms of the technology theoretically available to Starfleet, especially considering the risks entailed in exploring unknown planets.

Unfortunately, one of the things that Star Trek's writers discovered was that the biofilter made it difficult to tell certain kinds of stories. As a result, they invented the theory that the biofilter was only effective against known organisms, thus making it possible for the occasional unknown virus to wreak havoc aboard the ship.

bioregenerative field

Radiated energy used in biomedical applications to accelerate cellular growth.

Dr. Bashir used such a field to accelerate cells found in Ibudan's quarters that later developed into a clone of Ibudan

cryonics

Old practice of cryogenically freezing a human just after death in the hopes that future medical advances would render their sickness curable.

Some cryogenically frozen bodies were actually sent into space in orbiting satellites for long term storage.

One such cryosatellite was discovered in 2364 by the crew of the Enterprise-D. Cryonics was something of a fad in the late 20th century but fell into disuse by the mid-21st century.

Direct reticular stimulation was unsuccessfully attempted when Natasha Yar was critically wounded by Armus.

(Skin of Evil [TNG])

DNA

Acronym for deoxyribonucleic acid, a complex chemical chain containing the genetic codes enabling the reproduction of life on many planets.

Virtually every individual life form on such planets has a DNA code, which contains information common to that species, as well as distinguishing information unique to that individual. Because of this, DNA sequencing can be used as a means of positively identifying an individual, although it cannot distinguish between the individual and a clone.

Many humanoid species throughout the galaxy share a common DNA structure, a characteristic that was recently discovered to be due to a humanoid species that lived some four billion years ago that seeded many planets with primordial genetic material.

(The Chase [TNG])

(Ethics [TNG])

glial cells

More specifically known as neuroglia; tissue that forms the supporting elements of the nervous system which play an important role in reacting to injury or infection.

Kobliad Rao Vantika placed his neural patterns or consciousness in a microscopic generator. He used a weak electrical charge as a bio-coded message, placing it under his fingernails.

When Dr. Bashir found Vantika injured, the Kobliad scratched the physician and introduced the microscopic generator into Bashir's skin. The bio-coded message was then transferred to Bashir's neuroglia cells and straight to his brain, where Vantika's consciousness was stored.

invidium

A substance formerly used in medical containment fields.

Invidium fell out of general use in the 23rd century, although a few races continued its application into the 24th century. Invidium had the unusual property of being undetectable by normal internal sensor scans aboard starships. It was also highly reactive, capable of triggering spontaneous nucleosynthesis as well as malfunctions in various high power systems.

Invidium used in a medical shipment from the Mikulaks accidentally leaked out of a broken storage canister, causing a variety of serious malfunctions aboard the Enterprise-D in 2366.

The invidium was rendered inert by flooding contaminated areas with gaseous cryonetrium.
