Patterns and Drivers of Soil Respiration under Long-Term Citrus reticulate in Southern China.

Soil respiration (Rs) is a major source of carbon emission in terrestrial ecosystems. Despite the fact that the influence of land use practice on Rs has been widely studied, the patterns and drivers on Rs of Citrus reticulata cultivation, a worldwide land use practice are unclear. In this current study, we investigated the influence of long-term cultivation of Citrus reticulata (CO) and of CO intercropped with soybean (CB) on soil nutrients, water availability, and Rs in southern China.

Exposure to 3G mobile phone signals does not affect the biological features of brain tumor cells.

Background: The increase in mobile phone use has generated concerns about possible risks to human health, especially the development of brain tumors. Whether tumor patients should continue to use mobile telephones has remained unclear because of a paucity of information. Herein, we investigated whether electromagnetic fields from mobile phones could alter the biological features of human tumor cells and act as a tumor-promoting agent.

[Establishment of a Wistar rat model bearing brain glioma C6 cells and its experimental application].

Objective: To establish a rat model bearing brain glioma and investigate the optimal conditions for its experimental application.

Methods: C6 cells were implanted into the unilateral brain hemisphere of 20 Wistar rats. The growth behaviors of the brain tumor and behavioral changes of the rats were observed at different time points after the implantation.

Localization and distribution of magnetic chemotherapeutic drugs with magnetic targeting in rat brain.

Background: Magnetic targeting therapy may be a new method for the treatment of malignent tumors. The purpose of this study was to investigate the localization and distribution of ferrofluid microsphere of human serum albumin methotrexate (FM-HSA-MTX) carriers in the brain and to explore the magnetic targeting chemotherapy for malignant brain tumor.

Methods: Ninety SD rats were divided into three groups: targeting group, non-magnetic targeting group, and control group.
