Respiratory maneuvers can uncover manifestations of myocardial ischemia. Some pulse wave characteristics are associated with significant coronary artery disease (S-CAD). An innovative test using the respiratory stress response (RSR) has been developed for the detection of S-CAD based on spectral analysis of finger pulse wave oscillations measured using photoplethysmography (PPG) during deep, paced breathing at a rate of 6 breaths per minute (0.1 Hz) for 70 seconds. We evaluated this test (RSR) as an indicator of S-CAD.

    In women infected with HIV undergoing LEEP, an increase in genital HIV shedding was observed at 2 but not at 4 weeks post-procedure. The current recommendation for women to abstain from vaginal intercourse for 4 weeks seems adequate to reduce the theoretical increased risk of HIV transmission foll...

    Our results indicate that treatment of cancer cells with PF-04691502 reduces cell viability and inhibits cell growth in a dose-dependent manner. PF-04691502 triggers apoptosis via a mitochondrial pathway, accompanied by activation of caspase-3, caspase-9, and Poly(ADP-Ribose) Polymerase (PARP). Pre-...
