Diversity of medium and small-sized soil fauna community in different urban-rural green spaces and its influencing factors in Nanchang, China.

Urbanization is one of the important factors leading to biodiversity loss and habitat fragmentation. As an important component of urban ecosystem, soil fauna community plays a key role in improving soil structure and fertility, and promoting material circulation of urban ecosystem. To investigate the distribution characteristics of medium and small-sized soil fauna community in green space and the mechanisms underlying their responses to environmental change during urbanization, we selected 27 green space plots with a gradient of urban, suburban, and rural areas in Nanchang City as study objects, and measured plant parameters, soil physicochemical properties, and distribution characteristics of soil fauna community in these plots.

Dominant protozoan species in rhizosphere soil over growth of . in Northeast China.

This paper identified the dominant protozoan species in the four layers of rhizosphere soil during the six growth stages of . and analyzed the correlations of the abundance and diversity of the dominant protozoan species with soil properties at different growth stages and soil depth. A total of 15 species of protozoa were identified; among them, sp.

Propafenone suppresses esophageal cancer proliferation through inducing mitochondrial dysfunction.

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignant tumors with poor survival and limited therapeutic options. The aim of this study is to identify novel anticancer strategies from existing Food and Drug Administration (FDA)-approved drugs that have been used to clinically treat other diseases. Here, propafenone, an antiarrhythmic medication, was found to induce apoptosis and exert a significantly inhibitory effect on the proliferation and colony-forming ability of ESCC cells in a dose-dependent manner without observed cytotoxicity on normal esophageal epithelial cells.

Isodeoxyelephantopin induces protective autophagy in lung cancer cells via Nrf2-p62-keap1 feedback loop.

Isodeoxyelephantopin (ESI), isolated from Elephantopus scaber L. has been reported to exert anticancer effects. In this study, we aimed to investigate whether and how cancer cells exert protective responses against ESI treatment.

[An outbreak of endemic typhus in Baoshan city, Yunnan province].

Objective: To understand the epidemiologic characteristics of endemic typhus in Baoshan city.

Methods: Epidemiological data were collected and characteristics were analyzed. IgG antibody (Ab) of Rickettsia mooseri and Orientia tsutsugamushi in serum of patients were tested using both Weil-Felix and IFA method.

[Survey on human rabies cases and its viral molecular biological features in Baoshan city, Yunnan province].

Objective: To understand the epidemiological features of two rabies cases in Baoshan city year 2006 and 2007 and to analyze its source of infection.

Methods: Questionnaires were used to do the epidemiological survey on each of the rabies cases. Brain tissue samples of rabies patients were collect to detect the rabies virus by direct immunofluorescence assay (DFA) and RT-PCR assay.
