White mulberry Morus alba and jackfruit Artocarpus heterophyllus are two of seven chosen Vietnamese folk plants which showed the highest tyrosinase inhibition activity. Besides, both of them showed antioxidant and antibacterial activities. Especially, the Sulforhodamine B (SRB) assay test result of the root core extract of M. alba figured out its non-toxicity on foreskin fibroblasts.

以废弃酒瓶软木塞为原料,采用低成本、简单的水热方法合成碳量子点。通过TEM、FTIR、Raman、UV-Vis、PL光谱对碳量子点的结构和光学性能进行分析表征。结果表明,碳量子点的平均直径为6.2±2.7 nm,PL激发谱和碳量子点表面的官能团有关。用硫酸奎宁作为参考,碳量子点的量子效率为1.54%。将获得的碳量子点应用在骨髓间充质干细胞的细胞生物成像上,发现用碳量子点处理后,骨髓间充质干细胞分别在320~380 nm、450~490 nm和450~490 nm范围显示绿色、黄色和红色荧光,表明了碳量子点在荧光成像领域具有潜在的应用价值。

Background: The rate of uterus is successfully conserved following the treatment of scar pregnancy which is high so pregnancy outcome following caesarean scar ectopics is getting more and more attention. Objectives: To assess pregnancy course and outcome after conservative treatment of cesarean scar pregnancy. Methods: A retrospective case series of 40 patients become pregnancy after conservative treatment of cesarean scar pregnancy by Foley or Methotrexate and aspiration. Patients in present study were treated at Hung Vuong and Tu Du Hospital between 2015 and 2017. A telephone follow-up was conducted after cesarean scar pregnancy (CSP) treatment. The outcomes of these subsequent pregnancies and mode of delivery were all recorded. Results: In 40 pregnancies, there are 22 cases of intrauterine pregnancy with childbirth (55%);all babies were born healthy, with no complications recorded in pregnancy. 12 Women had recurrent scar ectopic (30%). There were 2 abortion cases, 2 cases of ectopic pregnancy, and 2 cases of early miscarriage. Conclusions: Our study shows that reproductive outcomes following treatment of caesarean scar ectopic pregnancies are favourable. The risk of recurrent caesarean scar ectopic pregnancy is a concern.

Introduction to education is one of the basic courses in teacher education professional education, it covers a wide range of subjects. Thus, in order to practice the management teaching goals, the interdisciplinary developed mathematical tools are applied for the study. The participants of this study are students in course of introduction to education, and the research instruments applied are rough set, grey structural modeling (GSM), and matrix based-structural modeling (MSM). The purposes of this paper are: 1) To logically analyze educational datasets to practice the scientific traits in education;2) To benefit from directed hierarchical analysis to identify and propose action planning;3) To construct core-oriented educational structure as the criterion-reference for one-lesson-multiple-design and to provide the whole scope and visualized analysis with GSM and MSM.

Two triterpenoid saponins, 6, 7, together with five known compounds were isolated from the roots of Arachis hypogea L. collected in Vietnam. Their structures were established by spectroscopic analysis (1D, 2D NMR and HRMS) as well as by comparison with those reported in the literature. Furthermore, the high content of resveratrol in the roots opens a new potential resource for pharmaceutical companies to prepare medicines from the wasted peanut roots.
