Coastal marshes have a significant capacity to sequester carbon; however, sea-level rise (SLR) is expected to result in prolonged flooding and saltwater intrusion in coastal regions. To explore the effects of SLR projections on net CO uptake in coastal marshes, we conducted a "double-check" investigation, including the eddy covariance (EC) measurements of the CO fluxes in subtropical coastal marshes along inundation and salinity gradients, in combination with a mesocosm experiment for analyzing CO flux components under waterlogging and increased salinity conditions. During the same measurement periods, the net ecosystem CO exchange (NEE based on the EC dataset) in an oligohaline marsh was higher than that in a low-elevation mesohaline marsh, whereas the NEE was lower than that in a high-elevation freshwater marsh.

Better understanding of oncogenes as well as synthetic lethal interactions with oncogenes will lead to new strategies for tumor-specific treatment. It is well known that mutant p53 plays an important role in tumorigenesis and tumor development.

Methods to identify these characteristics by using remotely sensed time series data have previously been proposed. However, these methods often have a mathematical basis, and more effort is required to better illustrate the ecological meanings of land-cover characteristics.

Remote sensing technique has recently been used to monitor its distribution, but the similar morphology and canopy structure among S. alterniflora and its neighbor species make it difficult even with high-resolution images.

Objective: This study was to present the survival of advanced cancer patients and explore the influence of various factors on survival time as well as survival rate. The results provide guidelines for clinical practice of cancer treatment.
Methods: Follow-up of 674 advanced cancer patients was performed in a hospice.
HIV prevalence among men who have sex with men (MSM) has increased rapidly in China. Behavioral and biologic interventions are the key to control the spreading of HIV in the MSM population and the primary strategy for reducing the spread of AIDS in China. The objective of this study is to explore the relationship among HIV-related knowledge, the basic information of respondents, service utilization and risky sexual behavior.
