001). LVEDV remained unchanged (p=0.81) and LVESV decreased with -9 +/- 18% (p<0.05) causing LVSV to increase with 8 +/- 3% (p<0.05). RVEDV and RVESV decreased by -7 +/- 10% and -24 +/- 14% respectively,
(p<0.001) and RVSV increased 5 +/- 17% during exercise although not statistically significant (p=0.18). Longitudinal contribution to RVSV decreased during exercise by -6 +/- 15% (p<0.05) but was unchanged for LVSV (p=0.74). THV decreased during exercise by -4 +/- 1%, (p<0.01) and total heart volume variation (THVV) increased during exercise from 5.9 +/- 0.5% to 9.7 +/- 0.6% (p<0.001).
Conclusions: Cardiac volumes and function are significantly GDC-0068 inhibitor altered during supine physical exercise. THV becomes significantly smaller due to decreases in RVEDV whilst LVEDV remains unchanged. THVV and consequently radial pumping increases during exercise which may improve diastolic suction during the rapid filling phase.”
“Objective. To evaluate the prevalence of defective placental adhesion (DPA) in voluntary termination of second-trimester pregnancy and the risk of DPA recurrence in subsequent AZD9291 pregnancies.
Methods. We retrospectively reviewed the records of all patients who underwent voluntary second-trimester pregnancy termination in the period between January 2000 and December 2009. In all cases, the fetus and the placenta were submitted
to pathological examination accordingly to our clinical protocol.
Results. Four
hundred twenty-seven cases of voluntary termination of second-trimester click here pregnancy were included in the study. Ten histologically confirmed cases of placenta accreta were observed (2.3%). Two patients with histological diagnosis of placenta accreta were lost at follow-up. Among the eight remaining patients, six had further pregnancies. Overall, nine pregnancies were recorded, and placenta accreta recurred in one patient.
Conclusions. This study shows that DPA occurs in 2.3% of second-trimester voluntary termination of pregnancy; these patients should have an accurate ultrasound examination of the placenta in subsequent pregnancies.”
“BACKGROUND: Nitrogen-doped multi-walled carbon nanotubes (CNx) and cup-stacked-type carbon nanofibres (CST) were modified with nitric acid, at 85 degrees C, for 1-3 h to enhance their cation adsorption capacity, and were used for cadmium removal from aqueous solutions. These carbon nanostructures were characterized by SEM, EDX, FTIR, BET surface area, TGA and acid/base titrations. In addition, cadmium adsorption experiments were carried out at different pH values and constant temperature.
RESULTS: EDX and FTIR revealed a 0.4 times increase in oxygen content after acid treatment, which was reflected in an increment of up to 1.93 mmol g(-1) of acid sites and in a shift of about two units of the zero point charge to lower pH values. The BET surface area, in general, decreased as the oxidation time increased.
