The malignancy risk of endometrial polyps in postmenopausal women was correlated with the presence or absence of abnormal uterine bleeding. Of 481 postmenopausal women who presented with endometrial polyps at diagnostic hysteroscopy between 2004 and 2007, 48.9% were asymptomatic and 51.1% had postmenopausal uterine bleeding. Transvaginal ultrasound revealed abnormal endometrial thickness in 60.0% vs. 57.7%, polyps in 37.9% vs. 32.9%, endometrial tumors in 1.3% vs. 0.8%, and submucosal myomas in 0.9% vs. 2.0% by the absence or presence of bleeding. Around three‐fourth of the polyps were removed. Histopathologic diagnoses showed mucous polyps in 93.7 of asymptomatic women compared to 80.7% of those with bleeding, while endometrial tumors were only seen in those bleeding (7.2%). The malignancy risk within endometrial polyps in postmenopausal women varies with the presence of vaginal bleeding, and is minimal in asymptomatic women.

The best response and overall survival rates were achieved in Group A with the NACT scheme of bleomicine.

Our data highlight the importance of epigenetically assessing OSCCs to identify key genes that may serve as diagnostic and prognostic biomarkers and, potentially, as candidate therapeutic targets.

In this paper we apply the KInematic Waveform Inversion (KIWI) tools to the study of smallto-moderate earthquakes in southwest (SW) Iberia. The earthquakes have magnitudes in the range M L 3.5-4.9, with the exception of one earthquake with magnitude M L 6.0. Most events are located offshore, are recorded with a large azimuthal gap and generate waves that travel through a strongly heterogeneous crustal structure. We obtain new estimates of centroid, depth, seismic moment, strike, dip and rake for 12 of the 29 studied events. The earthquakes whose waveforms we cannot successfully model are (1) located too far from the stations, (2) have small magnitude, hence low signal-to-noise ratio or (3) are located within the Cadiz basin, which is a major sedimentary basin that affects wave propagation notably. Our results indicate that onshore earthquakes occur at shallow depths (<15 km), whereas offshore earthquakes occur deeper, down to 46 km. Focal mechanisms indicate transpressive faulting.

Seismic ambient noise tomography is applied to central and southern Mozambique, located in the tip of the East African Rift (EAR). The deployment of MOZART seismic network, with a total of 30 broad-band stations continuously recording for 26 months, allowed us to carry out the first tomographic study of the crust under this region, which until now remained largely unexplored at this scale. From cross-correlations extracted from coherent noise we obtained Rayleigh wave group velocity dispersion curves for the period range 5-40 s. These dispersion relations were inverted to produce group velocity maps, and 1-D shear wave velocity profiles at selected points. High group velocities are observed at all periods on the eastern edge of the Kaapvaal and Zimbabwe cratons, in agreement with the findings of previous studies. Further east, a pronounced slow anomaly is observed in central and southern Mozambique, where the rifting between southern Africa and Antarctica created a passive margin in the Mesozoic, and further rifting is currently happening as a result of the southward propagation of the EAR. In this study, we also addressed the question concerning the nature of the crust (continental versus oceanic) in the Mozambique Coastal Plains (MCP), still in debate. Our data do not support previous suggestions that the MCP are floored by oceanic crust since a shallow Moho could not be detected, and we discuss an alternative explanation for its ocean-like magnetic signature. Our velocity maps suggest that the crystalline basement of the Zimbabwe craton may extend further east well into Mozambique underneath the sediment cover, contrary to what is usually assumed, while further south the Kaapval craton passes into slow rifted crust at the Lebombo monocline as expected. The sharp passage from fast crust to slow crust on the northern part of the study area coincides with the seismically active NNE-SSW Urema rift, while further south the Mazenga graben adopts an N-S direction parallel to the eastern limit of the Kaapvaal craton. We conclude that these two extensional structures herald the southward continuation of the EAR, and infer a structural control of the transition between the two types of crust on the ongoing deformation.
