Patent CA-2505736-A1 (CA)
Inventor: DOWNIE NEIL ALEXANDER
IPC: G05D7/06
Filed: 2003-11-20
Abstract: A volume flow controller (1) for controlling the flow of a gas mixture of variable proportions through a conduit (3) has a valve means (5) for regulating the flow of gas through the conduit, a drive means (9) for driving the valve means, a volumetric flow meter (7), such as a Pelton wheel, for measuring the flow of gas through the conduit, which provides a feedback signal (29) for comparison with a setpoint signal (17) in an amplifier (15) which generates an adjustment signal (11) which is fed to the drive means. The setpoint signal is generated by a setpoint signal generating means (19), which comprises a potentiometer (21) for inputting a value corresponding to a desired flow rate and a slowdown circuit (23) consisting of a resistor (25) and a capacitor (27) for delaying the change in the setpoint from the previous setpoint to the desired setpoint for a period of time sufficient to compensate for the delay in response inherent in the volumetric flow meter, thus providing smooth and stable control of the gas flow. Preferably, the potentiometer is a digital potentiometer (403), which voltage is variable by independent manipulation of rotary encoders (417).

An artery locating sensor is provided on the distal end of at least obtuse angle between about 1200 and about 1700, one of the clamping elements. Preferably, the artery locating sensor is a Doppler ultrasound blood flow sensor. After birth, the clamping device is inserted into the female patient's post partum vaginal canal and advanced therein until one of the clamping elements is in the patient's uterine cervix and the other clamping element is on the exterior of the uterine cervix. The clamping element on the exterior of the patient's uterine cervix is pressed against the patient's vaginal fornix and the clamping device closed so as to occlude the uterine artery disposed within tissue grasped by the clamping device. The clamping device is locked in the closed configuration and maintained in the condition until the patient's uterus is sufficiently clotted up to ensure termination of the hemorrhaging, typically about 5 minutes to about 7 hours.

Abstract: The protein pRb2/p130 represses expression of the ER-.alpha. gene. Blocking pRb2/p130 expression or altering ER-.alpha. gene methylation to alter pRb2/p130 complex binding allows transcriptional activity of the ER-.alpha.  gene to be restored. Detecting and regulating the methylation state of the ER-.alpha. gene, optionally together with detecting and regulating pRb2/p130 multimolecular complexes bound to the ER-.alpha. gene promoter, allows estrogen-insensitive breast cancer cells to be identified, so that an accurate prognosis can be obtained and an appropriate course of treatment administered.  Also, inhibiting pRb2/p130, or altering the methylation pattern of the ER-.alpha. gene by targeting DNMT 1 I n the pRb2/p 130-E2F4/5-HDAC 1-DNMT1-SUV39H1 complex, allows estrogen-insensitive breast cancer cells to be converted to estrogen-sensitive breast cancer cells.
