A new microparticle-based delivery system was synthesized from reactive oxygen species (ROS)-responsive poly(propylene sulfide) (PPS) and tested for "on demand" antioxidant therapy. PPS is hydrophobic but undergoes a phase change to become hydrophilic upon oxidation and thus provides a useful platform for ROS-demanded drug release. This platform was tested for delivery of the promising anti-inf...

BACKGROUND Accurate prognostication of the trajectory of an illness provides multiple benefits in end-of-life care. Prognostic information facilitates more realistic decision making regarding ongoing treatment, fosters risk-benefit considerations of specific interventions, and contributes to appropriate utilization of health care services. OBJECTIVE The Palliative Performance Scale (PPS) has ...

Few data are available in the literature regarding the effect of pentosan polysulfate (PPS) on normal and fibrotic rat livers. In addition, the combination of PPS and carbon tetrachloride (CCl4) has not been studied so far. The objective of this study was to assess the effect of PPS on rat livers treated or not with CCl4 for the induction of liver fibrosis. The study consisted of four stages: 1...

The reordering window in PPS introduces latency, however, and this latency might be problematic for video surveillance applications, which stream live video. In live video streaming, the latency characteristics of the streaming mechanisms partially determine the freshness of the video content. The freshness of the video content, which is measured by the end-to-end latency from a frame being cap...

Although an increasing number of hospitals are reporting net losses from the Medicare prospective payment system (PPS) for inpatient care, overall hospital facility profit rates remain stable. Hospitals that reported net profits in the Medicare inpatient PPS sector in PPS 7 (1990) had smaller increases in Medicare expenses than hospitals that reported PPS losses in PPS 7. Medicare PPS inpatient...

Postcoital psychological symptoms (PPS) is a virtually unexplored phenomenon in the female population even though women frequently complain about irritability and motiveless crying after intercourse and/or orgasm. The aim of this study was to explore the epidemiology and genetic influences of PPS in a UK population sample of women. 1,489 unselected female twins aged 18-85 completed questions on...
