Abstract A knockout study with VDR si-RNA confirmed the mediating role of VDR. VDR target genes induced by 1,25-(OH)2D3 were down-regulated with the co-treatment of PS121912. This process was highly dependent on the recruitment of coregulators that in case of CYP24A1 was SRC2.

- Save. A digital video recorder, or DVR, is a device that is used to record digital TV programs onto a hard disk. Connecting the DVR to an alternate video recording device allows you to record video from the DVR to an external storage medium such as a DVD disc. Perhaps you've made a DVR recording of a concert, interview or comedy special, and you just want to save the program's audio without the video on an external disc.

ReviewVitamin D receptor signaling mechanisms: Integrated actions of a well-defined transcription factor Other emergent areas of 1α,25(OH)2D3 action are in the control of immune functions, cellular growth and differentiation. All genomic actions of 1α,25(OH)2D3 are mediated by the transcription factor vitamin D receptor (VDR) that has been the subject of intense study since the 1980’s. Thus, vitamin D signaling primarily implies the molecular actions of the VDR.

EMDR: Eye Movement Desensitization and Reprocessing Eye movement desensitization and reprocessing (EMDR) is a fairly new, nontraditional type of psychotherapy. It's growing in popularity, particularly for treating post-traumatic stress disorder . PTSD often occurs after experiences such as military combat, physical assault, rape, or car accidents.

- The new FT1DR provides three digital modes (V/D mode, Voice FR mode, Data FR mode) and a Analog mode: · V/D mode is Voice and Data communication in the same time frame. This mode enables the transceiver to send voice data with GPS position data and ID data in the same time frame.Also, this mode can pass the voice data with strong error correction data to stabilize the digital communication.. Voice FR Mode (Voice Full Rate Mode) This mode uses the entire 12.5 kHz bandwidth to transmit digital voice data. The larger voice data size allows voice communication with high sound quality. Use this mode for pleasing sound quality communication between amateur radio friends.

Optical time-domain reflectometer Optical time-domain reflectometer. An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. An OTDR is the optical equivalent of an electronic time domain reflectometer. It injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or reflected back from points along the fiber.

- These drives are sometimes also called variable voltage variable frequency (VVVF) drives, for the voltage is varied along with frequency. A variable frequency drive system generally consists of an AC motor, a controller and an operator interface. A Variable Frequency Drive HARSVERT-A series VFD is a masterpiece of outstanding performance and high reliability, which is widely used for the energy-saving application of the normal motors of fans, pumps, compressors, mills, conveyors and lifts.

- EMDR Therapists EMDR (Eye Movement Desensitization and Reprocessing) is an information processing therapy that helps clients cope with trauma, addictions, and phobias. During this treatment, the patient focuses on a specific thought, image, emotion, or sensation while simultaneously watching the therapist's finger or baton move in front of his or her eyes.

What is switched digital video (SDV)? When you tune to an SDV channel, your Spectrum Receiver or tuning adapter tells the network that you want to watch the channel. The network then sends that channel to your home. This back and forth communication makes SDV a bidirectional service. To receive bidirectional services, you need a bidirectional device.

Vector Network Analyzer VNA Tutorial The vector network analyzer, VNA is a form of RF network analyzer widely used for RF design applications. A vector network analyser is a test system that enables the RF performance of radio frequency (RF) and microwave devices to be characterised in terms of network scattering parameters, or S parameters.

Volt-ampere reactive (Redirected from MVAr). In electric power transmission and distribution, volt-ampere reactive (var) is a unit by which reactive power is expressed in an AC electric power system. Reactive power exists in an AC circuit when the current and voltage are not in phase.he reactive power (measured in units of volt-amperes reactive or var) is given by: where is the phase angle between the current and voltage. Q refers to the maximum value of the instantaneous power absorbed by the reactive component of the load.

Virtual retinal display A diagram showing the workings of the virtual retinal display. A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display (like a television) directly onto the retina of the eye. The user sees what appears to be a conventional display floating in space in front of them. 1 History.

Virtual circuit A virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data. The term virtual circuit is synonymous with virtual connection and virtual channel.atalink layer and network layer virtual circuit protocols are based on connection oriented packet switching, meaning that data is always delivered along the same network path, i.e., through the same nodes.

- VDC= Vehical Dynamic Control. A sudden change in surface consistency can affect your car's stability during evasive driving. Vehicle Dynamic Control* uses various sensors to help determine your steered path and keep you in control. If your vehicle begins to understeer (plow forward) or oversteer (fishtail), VDC applies appropriate brake pressure to individual wheels and/or reduces engine output to help keep your vehicle on its steered path.

- Simply put, a VFD is a power conversion device. The VFD converts a basic fixed-frequency, fixed voltage sine-wave power (line power) to a variable-frequency, variable-voltage output used to control speed of induction motors.A basic block diagram of this process is depicted in Fig. 1.he VFD converts a basic fixed-frequency, fixed voltage sine-wave power (line power) to a variable-frequency, variable-voltage output used to control speed of induction motors.

Flight recorder The flight data recorder (FDR) is a device that preserves the recent history of the flight through the recording of dozens of parameters collected several times per second. The cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit including the conversation of the pilots. The two recorders give an accurate testimony, narrating the aircraft's flight history, to assist in any later investigation.
