Several authors reported lower frequencies of protein sequence convergence between more distantly related evolutionary lineages and attributed this trend to epistasis, which renders the acceptable amino acids at a site more different and convergence less likely in more divergent lineages. A recent primate study, however, suggested that this trend is at least partially and potentially entirely a...

PURPOSE In the present study, the three-dimensional power Doppler was used as a quantitative method to evaluate its reliability in detecting and assessing of gestational trophoblastic disease (GTD). METHODS 52 GTD patients who received diagnosis and treatment at the first affiliated hospitals of Xi'an Jiaotong University in China between 2011 and 2013 were evaluated using Voluson E8 (GE Medic...

The grapevine trunk disease (GTD) has been considered a real threat on grape production. This study aimed to identify the GTD causing agents in Palestinian orchards and evaluate efficacy of bacteria control under vitro conditions. Two fungal isolates; Fusarium solani isolate GR Neofusicoccum parvum GR3 were identified diagnosed using PCR BLASTn analysis. After that, five bacterial isolates test...

placental site trophoblastic tumor (pstt) is the rare variant of gestational trophoblastic diseases (gtd), which differs histologically and immunologically from gtd. diagnosis of pstt is often difficult and delayed. in most cases, diagnosis is not possible until the surgery is performed. the most therapeutic choice is hysterectomy and it is usually successful. here we report two cases of pstt.

We construct a numerical scheme based on the Liouville equation of geometric optics coupled with the Geometric Theory of Diffraction (GTD) to simulate the high frequency linear waves diffracted by a corner. While the reflection boundary conditions are used at the boundary, a diffraction condition, based on the GTD theory, is introduced at the vertex. These conditions are built into the numerica...
