Birth Through Knowledge

Birth Through Knowledge (aka BTK) was a Canadian hip-hop/rock band best known for their 1998 single "Peppyrock," the video for which was nominated for the 1998 MuchMusic Best Video Award. The band consisted of Lo-Ki (vocals), Stone Groove (vocals), DJ Spinz (turntables), Adam Carlo (bass),Sam Cino (drums,percussion) and Matt deMatteo (drums).

After signing onto the Tommyboy/Ignition label, BTK released one album "Birth Thru Knowledge" in 1998.

BTK first came to attention when their song "Corncob Pipe" was included on the sampler disc that Korn released alongside Follow the Leader. They were the first indie band to ever open the main-stage at Edgefest '97. In 1998, the band toured with the Beastie Boys and with Our Lady Peace. They appeared in the 1998 Summersault tour.

The band won the 1997 MuchMusic Best Independent Video Award for "Superchile." They were also nominated for a Juno Award in 1999 in the Best Alternative Album category, losing to Rufus Wainwright.

Bruton's tyrosine kinase

Bruton's tyrosine kinase (abbreviated Btk or BTK) also known as tyrosine-protein kinase BTK is an enzyme that in humans is encoded by the BTK gene. BTK is a kinase that plays a crucial role in B-cell development.

Function

BTK plays a crucial role in B cell maturation as well as mast cell activation through the high-affinity IgE receptor.

Btk contains a PH domain that binds phosphatidylinositol (3,4,5)-trisphosphate (PIP3). PIP3 binding induces Btk to phosphorylate phospholipase C, which in turn hydrolyzes PIP₂, a phosphatidylinositol, into two second messengers, inositol triphosphate (IP3) and diacylglycerol (DAG), which then go on to modulate the activity of downstream proteins during B-cell signalling.

Clinical significance

Mutations in the BTK gene are implicated in the primary immunodeficiency disease X-linked agammaglobulinemia (Bruton's agammaglobulinemia). Patients with XLA have normal pre-B cell populations in their bone marrow but these cells fail to mature and enter the circulation. The Btk gene is located on the X chromosome. At least 400 mutations of the BTK gene have been identified.

Åled

Åled is a locality situated in Halmstad Municipality, Halland County,Sweden, with 1,634 inhabitants as of 2010. The community is located just over 10 km northeast of Halmstad along Swedish national road 26. The Nissan river runs though the area.

Spånstad is located in the northwestern part of the village, and Enslöv is in the east. Northeast of Åled there is a small lake named Torsjön and "Gröta håla" (a giant's kettle). Åled is located along the Halmstad-Nässjö railway line, formerly part of Halmstad Nässjö Railways, HNJ. It was completed in 1882.

The musician Göran Fritzson from Gyllene Tider was born and raised in Åled.

Light-emitting diode

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

An LED is often small in area (less than 1 mm²) and integrated optical components may be used to shape its radiation pattern.

Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

Astray is the sixth album from the American band, Samiam, released in 2000 on Hopeless Records and Burning Heart Records.
