Removal of sulfamethoxazole and antibiotic resistance genes in paddy soil by earthworms (Pheretima guillelmi): Intestinal detoxification and stimulation of indigenous soil bacteria.

Vermiremediation, which use earthworms to remove contaminants from soil, has been proven to be an alternative, low-cost technology. However, the effects of earthworm activity, especially the degraders in earthworm intestines, on the fate of sulfamethoxazole (SMX), and the effects of intestinal bacteria on degrading bacteria in soil are unclear. In this study, the effects of earthworms on the fate of SMX and related antibiotic resistance genes (ARGs) were investigated.

Carbon-Phosphorus Coupling Governs Microbial Effects on Nutrient Acquisition Strategies by Four Crops.

Plants adjust root morphological and/or exudation traits in response to phosphorus (P) mobilization mediated by microorganisms. We hypothesized that straw application coupled with P fertilization would influence microbial P and then root nutrient-acquisition strategies related to crop growth. Root morphological (length and average diameter) and exudation traits (acid phosphatase and carboxylates) of , , and in response to microbial P dynamics were characterized in no-P and P-fertilized soil with/without straw addition.

A novel electrochemical sandwich-like immunosensor based on carboxyl TiCT MXene and rhodamine b/gold/reduced graphene oxide for .

(LM) is one of the most common food-borne pathogens and can induce a series of diseases with a high mortality rate to humans; hence, it is very necessary to develop a highly sensitive method for LM detection. Based on this need, a new sandwich-like electrochemical immunosensing platform was developed herein by preparing carboxyl TiCT MXene (C-TiCT MXene) as the sensing platform and rhodamine b/gold/reduced graphene oxide (RhB/Au/RGO) as the signal amplifier. The high conductivity and large surface area of C-TiCT MXene make it a desirable nanomaterial to fix the primary antibody of LM (PAb), while the prepared Au/RGO/RhB nanohybrid is dedicated to assembling the secondary antibody (SAb) of LM, offering an amplified response signal.

Effects of long-term integrated agri-aquaculture on the soil fungal community structure and function in vegetable fields.

The diversity and community structure of soil fungi play an important role in crop production and ecosystem balance, especially in paddy-upland vegetable field systems. High-throughput sequencing was used to study changes in the soil fungal community structure and function in paddy-upland vegetable field systems. The results showed that compared with traditional planting, the diversity and community structure of soil fungi were changed by the combination of flooding and drought, the Shannon index increased by 11.

Effect of nitrogen application rate on soil fungi community structure in a rice-fish mutualistic system.

Rice-fish mutualistic production systems rationalise the use of water and soil resources in an improved approach to sustainable food production. However, drivers of fungi community structure in paddy soil, including effects of nitrogen (N) application rate, are unclear in these systems. Here, we assessed soil fungi community and soil physicochemical responses in paddy soil to contrasting rates of N application in a rice-fish system.

Increased planting density of Chinese milk vetch () weakens phosphorus uptake advantage by rapeseed () in a mixed cropping system.

Neighbouring plants can affect plant growth through altering root morphological and physiological traits, but how exactly root systems respond to neighbouring plants with varied density, determining nutrient uptake and shoot growth is poorly understood. In a pot-based experiment, rapeseed was grown alone (single rapeseed), or mixed with 3, 6, or 15 Chinese milk vetch plants. As controls, monocropped Chinese milk vetch was grown at the same planting density, 3, 6, or 15 plants per pot.

A systematic review of growth hormone for hip fractures.

Objective: To evaluate the clinical effectiveness of growth hormone (GH) for hip fractures.

Design: Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Library (2011, 3 issue), PubMed (1966 to October 2011), EMBASE (1974 to October 2011), OVID database (1963 to October 2011), Chinese Bio-medicine database (1978 to October 2011), China Journal Full-text Database (1979 to October 2011), and VIP database (1989 to October 2011). Randomized controlled trials (RCTs) of GH treatment for hip fractures were included.

[Anti-cervix-cancer effect of the co-immobilization of tumor necrosis factor-alpha and interferon-gamma].

To explore the effect of the co-photo-immobilization of Recombinant Human Interferon-r (IFN-gamma) and Recombinant Tumor Necrosis Factor (TNF-alpha) on the Hela cell cultivated in vitro. Co-immobilize the photoactive IFN-gamma and TNF-alpha on the polystyrene membrane; Cultivate the Hela cell on the cell culture polystyrene plate surface and set up the cultivation of the photo-immobilization IFN-gamma+TNF-alpha, Photo-immobilization IFN-gamma, nature (IFN-gamma, TNF-alpha, IFN-gamma+TNF-alpha). After 48 hours, the inhibition effect against Hela cells was studied in vitro by SEM and flow cytometry.
