We present a case in which a 26-year-old woman was admitted to the emergency room with abdominal pain. She was diagnosed with a ruptured ectopic pregnancy after a positive urinary pregnancy test and transvaginal ultrasound. Laparoscopic surgery showed intact pelvic Selleckchem Z-VAD-FMK organs and an ectopic mass on the omentum. The patient was treated successfully

with laparoscopic partial omentectomy, and pathologic examination confirmed an omental pregnancy. As evidenced by this case, laparoscopy can be useful to diagnose and treat unusually located ectopic pregnancies.”
“The fraction R of charges undergoing discharge during the time separating two electron pulses is derived from the induced current method developed in a scanning electron microscope. Irradiation is performed via a 10 keV defocused electron beam and low current density. The evolution of R with temperature (in the range 300-663 K) obeys to an Arrhenius type relation. Activation energies connected with the processes involved are deduced. In sapphire, no discernible selleck discharge is observed due to the dominance of deep traps. In silver doped sapphire, R increases sharply from 10% to 70% as the temperature rises from 360 to 420 K, with a corresponding activation energy of 0.51 eV. In contrast, in polycrystalline alumina processed by solid state sintering (grain diameters of 1.7, 2.7, and 4.5 mu m) the

degree of discharge increases continuously with temperature and grain size. The enhancement with grain

size indicates that the sintering conditions influence strongly the efficiency of a gettering effect. The activation energy below 573 K is about 0.12 eV independently of grain size. Above 573 K, a second activation energy of 0.26 eV appears for the smallest grain size sample. The results suggest that discharge may stem from a density of trapping states, associated to grain boundaries in sintered samples, rather than from a single trapping level linked to the doping element as Ag in sapphire.

“The reaction of tung oil (TO) and 1,1′-(methylenedi-4,1-phenylene) bismaleimide (BMI) in 1,3-dimethyl-2-imidazolidinone (DMI) at 150 degrees C for 4 h and subsequent precipitation gave TO/BMI prepolymer, which was cured at 200 degrees C for 2 h gave crosslinked TO/BMI 5-Fluoracil product with C=C ratio from 1/1 to 1/4. The FE-SEM analysis revealed that all the cured products are homogeneous and no phase separation was observed. The glass transition temperature and 5% weight loss temperature of the cured TO/BMI increased with increasing BMI content. The maximal tensile strength (38.1 MPa) and modulus (2.6 GPa) were obtained for the cured products with the C=C ratios of 1/2 and 1/3, respectively. To evaluate the reaction of TO and BMI, the model reaction products of TO and N-phenylmaleimide (PMI) in DMI were analyzed by (1)H-NMR spectroscopy.
