BACKGROUND The application of nanotechnology in biology and medicine represents a significant paradigm shift in the approach to the treatment of cancer. Evidence suggests that when exposed to near-infrared radiation (NIR), carbon nanotubes (CNTs) dissipate a substantial amount of heat energy. We have developed a novel nanocomposite polymer, polyhedral oligomeric silsesquioxane poly (carbonate-u...

BACKGROUND Canadian data describing inpatient palliative care unit (PCU) utilization are scarce. In the present study, we performed a quality assessment of a 24-bed short-term PCU with a 3-months-or-less life expectancy policy in a tertiary care setting. METHODS Using a retrospective chart review, we explored wait time (wt) for admission (May 2005 to April 2006), length of stay [los (February...

In developing countries including India, mixed traffic condition prevails on roads and highways. There is a wide variation in the static and the dynamic characteristics of different types of traffic. The only way of accounting for this non-uniformity for any traffic analysis in traffic stream is to convert all vehicles into a common unit and the most accepted unit for this purpose is passenger ...

Previous research on reach planning in humans has implicated a frontoparietal network, including the precuneus (PCu), a putative human homolog of the monkey parietal reach region (PRR), and the dorsal premotor cortex (PMd). Using a pro-/anti-reach task, electrophysiological studies in monkeys have demonstrated that the movement goal rather than the location of the visual cue is encoded in PRR a...

A combination of DNA macrorestriction analysis using pulsed-field gel electrophoresis and a serotyping method using three panels of monoclonal antibody was used to discriminate 43 epidemiologically unrelated Neisseria gonorrhoeae isolates requiring proline, citrulline, and uracil (PCU-) into 35 groups. This indicates that PCU- isolates of N. gonorrhoeae are not clonal.

The effect of chronic protein-calorie undernutrition (PCU) on cardiac structure, biochemistry, myocardial function, and left ventricular dynamics was studied in young, male, Long-Evans rats. Chronic PCU produced marked cachexia of the marasmic type (body weight decreased to 48% of normally nourished control rats) and cardiac atrophy (heart weight at 57% of control). Myocardial structure on ligh...

A new controlled release fertilizer was developed by coating urea particles with bio-based polyurethane. Coating materials were synthesized from liquefied wheat straw, isocyanate, and castor oil. The effects of liquefied solvents, mass ratio of liquid to solid, size of wheat straw, and reaction time during liquefaction process on the nitrogen release rate of polyurethane-coated urea (PCU) were ...

Postcomatose unawareness/vegetative state (PCU/VS) is an altered state of consciousness that may follow coma. It is characterized by wakefulness without awareness of self or the environment. While most frequently associated with trauma, it is also associated with anoxia, vascular injury or encephalitis. In this article, the clinical phenomenon of PCU/VS is explored using the content methodology...

Controlled release urea (CRU) is considered to enhance crop yields while alleviating negative environmental problems caused by the hazardous gas emissions that are associated with high concentrations of ammonium (NH₄⁺) and nitrate (NO₃-) in black soils. Short-term effects of sulfur-coated urea (SCU) and polyurethane-coated urea (PCU), compared with conventional urea, on NO₃- and NH₄⁺ in black s...

An unmet need exists for the development of next-generation multifunctional nanocomposite materials for biomedical applications, particularly in the field of cardiovascular regenerative biology. Herein, we describe the preparation and characterization of a novel polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane (POSS-PCU) nanocomposite polymer with covalently attached anti-CD34...
