Dandelion ( Genus): A Review of Chemical Constituents and Pharmacological Effects.

Dandelion ( genus) is a perennial herb belonging to the Asteraceae family. As a well-known and extensively studied genus, dandelion comprises numerous species. Some species have been widely used in both complementary and alternative medicine to clear heat, detoxify, activate blood circulation, dispel stasis, and discharge urine.

[Exploration of anatomical location of Baliao points of adult female].

Fifteen morphologically and structurally complete sacrum specimens of normotrophic adult females were choosen. Distances between posterior sacral foramina and median sacral crest,and between the cores of adjacent posterior sacral foramina were measured. Then statistical analysis was done so as to provide objective anatomical evidence for the surface localization of Baliao points.

Investigation of cracks in GaN films grown by combined hydride and metal organic vapor-phase epitaxial method.

Cracks appeared in GaN epitaxial layers which were grown by a novel method combining metal organic vapor-phase epitaxy (MOCVD) and hydride vapor-phase epitaxy (HVPE) in one chamber. The origin of cracks in a 22-μm thick GaN film was fully investigated by high-resolution X-ray diffraction (XRD), micro-Raman spectra, and scanning electron microscopy (SEM). Many cracks under the surface were first observed by SEM after etching for 10 min.

Well-aligned Zn-doped tilted InN nanorods grown on r-plane sapphire by MOCVD.

Well-aligned tilted Zn-doped InN nanorods have been grown successfully on r-plane sapphire in a horizontal metal-organic chemical vapor deposition system. All of the nanorods are symmetrically tilted in two opposite directions. X-ray diffraction and transmission electron microscopy measurements show that the nanorods are single-crystalline and have exactly the same epitaxial orientation as the a-plane InN film.
