Abstract Cocaine inhalation is an extremely rare but previously described association of spontaneous pneumomediastinum. We describe unusual case a well 20-year-old female who presented with five-day history central, pleuritic chest pain beginning one week after last cocaine inhalation. Blood tests were within the normal limits except for positive d-dimer. Clinical examination was unremarkable, ...

Background. Left ventricular mechanical efficiency is one of the most important measures of left ventricular pump performance. Several clinical studies, however, have shown that mechanical efficiency does not fall substantially as the heart fails. To clarify the insensitivity of mechanical efficiency to the change in pump performance, we analyzed human left ventricular mechanical efficiency, ap...

incompressible fluid between two infinite vertical parallel plates in the presence of constant temperature and mass diffusion has been investigated analytically. The method of Laplace transform is used to solve the dimensionless governing partial differential equations. The velocity, temperature and concentration profiles have been presented for different parameters like Prandtl number, Schmidt...

algorithms are worthy of considering and efficiently to be utilized in the network topological deployment and keeping the network integrity, (2) the Partial Swarm Optimization is much algorithmically easier and reliable, (3) Intelligent computation is a kind of optimal methodology to improve the network integrity.

Intensive research in bio-engineering has been conducted in the search for flexible biomaterials that could support cell growth and cells attachment. Flexible synthetic materials that support cell growth without the aid of synthetic extracellular matrix proteins are still rare. Cholesteryl liquid crystal containing cholesteryl moieties may have suitable biological affinity. Human keratinocytes ...

The development and survival of sand fly Phlebotomus papatasi Scopoli (Diptera: Psychodidae) larvae fed feces of Syrian hamsters, Mesocricetus auratus, that had been fed a diet containing novaluron were evaluated. In total, six larval diets were used in sand fly larval bioassays. Four groups of larvae were fed feces of hamsters that had been maintained on a diet containing either 0, 9.88, 98.8,...
