BACKGROUND: Cannulation of small arteries and veins in young children can be challenging. Although anesthesiologists frequently use ultrasound for placement of central venous lines and nerve blocks, its use for cannulation of small, peripheral vessels is less helpful. Ultrasound systems (7-15 MHz) currently used in clinical practice focus poorly at the ...

BACKGROUND: There is evidence that graduates of different medical schools vary in their preparedness for their first post. In 2003 Goldacre et al. reported that over 40% of UK medical graduates did not feel prepared and found large differences between graduates of different schools. A follow-up survey showed that levels ...

Pathogenic neoangiogenesis in Alzheimer's disease (AD) is due to amyloid-beta (Aβ) and results in blood-brain barrier (BBB) leakiness in AD. It likely occurs as a compensatory response to impaired cerebral blood flow and provides a strong link between brain vascularity and AD. Aβ immunotherapy is an experimental treatment for AD; ...

Phosphomolybdic acid (PMA) and phosphotungstic acid (PTA) efficiently catalyze the addition of H2O2 to β-diketones to form bridged 1,2,4,5-tetraoxanes. These reactions are not accompanied by the formation of monocyclic peroxides containing hydroxy and hydroperoxide groups or polymeric peroxides. The use of these catalysts made it possible to obtain bridged tetraoxanes ...

Recent reports have shown that the breast cancer incidence rate in the US stabilized after a sharp reduction in 2002 and 2003. It is important to continue monitoring breast cancer incidence rates according to age group, race/ethnicity, estrogen receptor (ER) status, and tumor stage. Age-standardized breast cancer incidence rates were ...
