Excitation and detection of evanescent acoustic waves in piezoelectric plates: Theoretical and 2D FEM modeling.

This paper presents the results of the theoretical and 2D FEM modeling excitation and detection of evanescent acoustic waves in piezoelectric plates. By application of 2D ordinary differential equations derived by Auld, we obtained the dispersion curves of A and SH waves in YX LiNbO and YX KNbO plates in proximity to a zero group velocity point. The branches corresponding to evanescent acoustic waves are distinguished.

Different Surgical Approaches to 313 Cesarean Scar Pregnancies.

Study Objective: To evaluate the efficacy of different surgical treatments for cesarean scar pregnancy (CSP).

Design: Retrospective study (Canadian Task Force classification II-3).

Setting: Affiliated university hospitals.

Endoscopy-assisted inguinal lymphadenectomy in vulvar cancer.

Objective: To explore the feasibility and efficiency of video endoscopic inguinal lymphadenectomy (VEIL) for vulvar cancer.

Methods: We evaluated 46 patients with vulvar cancer. Treatment included VEIL using the hypogastric subcutaneous approach (VEIL-H, 17 patients), VEIL with the limb subcutaneous surgical approach (VEIL-L, 8 patients), and open inguinal lymphadenectomy (OIL, 21 patients).

Icaritin inhibits decidualization of endometrial stromal cells.

The aim of the present study was to investigate the effects of Icaritin on the proliferation and decidualization of endometrial stromal cells (ESCs). A total of 20 specimens of endometrium were collected during hysterectomy at the Gynecology Department of Shenzhen Nanshan People's Hospital (Shenzhen, China) between August 2014 and December 2015. The endometrium was digested with high concentrations of collagenase and DNase and filtered with meshes, and then the glandular epithelial and stromal cells were separated by the adhesion purification method.

A novel anticancer agent, SKLB70359, inhibits human hepatic carcinoma cells proliferation via G0/G1 cell cycle arrest and apoptosis induction.

Hepatocellular carcinoma is one of the most common cancers in worldwide. We previously reported a novel thienopyridine derivative 3-amino-6-(3,4-dichlorophenyl) thieno[2,3-b]pyridine-2-carboxamide (SKLB70359) which possesses anticancer activity against hepatocellular carcinoma. In present study, we further investigated its anticancer activity and possible mechanism.

Synthesis and biological evaluation of novel acenaphthene derivatives as potential antitumor agents.

Twelve novel acenaphthene derivatives have been synthesized. The structures of all compounds were confirmed by ¹H-NMR, MS and elemental analysis. Their antitumor activities were evaluated in six human solid tumor cell lines, namely non-small cell lung cancer (H460), human colon adenocarcinoma (SW480), human breast cancer cell (MDA-MB-468 and SKRB-3), human melanoma cell (A375) and human pancreatic cancer (BxPC-3).
