Sunitinib in pretreated advanced non-small-cell lung carcinoma: a primary result from Asian population.

Sunitinib is an oral multitargeted tyrosine kinase inhibitor of VEGF receptors and PDGF receptors and is approved for the treatments of advanced renal cell carcinoma and gastrointestinal stromal tumors. However, only few studies were conducted to investigate the effectiveness of the use of sunitinib in NSCLC. This study evaluated the clinical activity and tolerability of sunitinib in previously treated advanced NSCLC in Asian population, which, to our knowledge, has not previously been studied.

A radio-frequency source using direct digital synthesis and field programmable gate array for nuclear magnetic resonance.

A radio-frequency (rf) source for nuclear magnetic resonance (NMR) is described. With the application of direct digital synthesis (DDS), the rf source has the ability to yield rf pulses with short switching time and high resolution in frequency and phase. To facilitate the generation of a soft pulse, a field programmable gate array (FPGA) cooperating with a pulse programmer is used as the auxiliary controller of the DDS chip.

Effect of early pregnancy on a previous lower segment cesarean section scar.

Objective: To summarize the manifestation, diagnosis, and early management of early pregnancy on a previous cesarean section scar.

Method: Fifteen cases of early pregnancies implanted on previous cesarean section scars were diagnosed and treated in two obstetrical centers.

Results: The 15 patients had light, painless vaginal bleeding and their serum beta-subunit human chorionic gonadotropin (beta-HCG) was elevated.

The application of NMR imaging to the studies of enhanced oil recovery in China.

The advantages of the application of NMR imaging to the studies of enhanced oil recovery methods that include polymer slug flooding, combination slug flooding, and thermal soaking are described.

Application of NMR imaging to steam foam flooding in porous media.

Applications of NMR imaging to examine the fluid distribution of steam foam flooding as a function of concentration and volume of surfactant solution, and residual oil saturation are described. The features examined include sweep efficiency, oil recovery, resistance factor, apparent viscosity, steam quality, and foam stability. The results illustrate that the injection procedure and residual oil saturation have a significant influence on steam foam flooding.
