Separation of Excess Fluoride from Water Using Amorphous and Crystalline AlOOH Adsorbents.

Aluminum hydroxide is an effective defluoridation adsorbent; however, the poor defluoridation performance limits its wide application. In this work, amorphous and crystalline AlOOH adsorbents are synthesized through hydrolysis of Al salts, and their defluoridation performances are evaluated in terms of adsorption capacity and rate, sensitivity to pH value, and water quality after defluoridation. The defluoridation performance of AlOOH is closely related to the hydrolysis pH value, but hardly to the type of Al salts.

Urbanization threaten the pollination of Gentiana dahurica.

With rapid spread of the urbanization, many environmental factors, such as climate, soil pH and nutrients have been changed. However, the plant pollination affected by urbanization was seldom conducted. Here, we studied the flower visitation rates, seed production, pollen limitation and flower morphological characters of Gentiana dahurica at 3 populations along an urban-peri-urban gradient around Xi'ning over 4 consecutive years, aiming to test the effects of urbanization on plant pollination service.

[Prezygotic reproductive isolation of two sympatric species of Ligularia weeds in eastern Qinghai-Tibet Plateau, China].

Reproductive isolation, the key process to prevent interspecific hybridization and keep the completeness and independence of species, is crucial to the formation and maintenance of biodiversity. The forming steps, methods and intensities of reproductive isolation between different species are not completely the same. Literatures on reproductive isolation between species provide valuable evidence for speciation and its maintenance.

[Treatment of calcaneal fracture by closed reduction and minimally invasive plate fixation assisted with bidirectional distractor distraction].

Objective: To investigate clinical effects of calcaneal fracture with closed reduction and minimally invasive plate fixation assisted with bidirectional distractor distraction.

Methods: From September 2015 to October 2016, 11 male patients(13 feet) with calcaneal fractures treated with bidirectional distractor distraction assisted with minimally invasive plate fixation were retrospectively studied. They were aged from 24 to 57 years old with an average of 36.

microRNA-608 inhibits human hepatocellular carcinoma cell proliferation via targeting the BET family protein BRD4.

Over-expression of the bromodomain and extraterminal (BET) family protein BRD4 is associated with hepatocellular carcinoma (HCC) progression. In the present study, we indentified a novel putative anti-BRD4 microRNA: microRNA-608 ("miR-608"). In HepG2 cells and primary human HCC cells, over-expression of miR-608, using a lentiviral construct, induced BRD4 downregulation and proliferation inhibition.

[Preliminary Investigation of Medicinal Plant Resources in Kangle County, Gansu Province].

Objective: To study the medicinal plant resources and their diversity in Kangle County, Gansu Province, and to provide scientific basis on utilization and protection of the medicinal plant resources of the county.

Methods: By field survey, sample collection, taxonomic identification and data verification methods.

Results: There were 258 species, 65 families in existing medicinal plants, of which 43 species, 39 genera and 24 families were national protection medicinal plants.
