Advantages of compost tea: Promotion of nitrogen influx into the fruit and improvement of fruit nitrogen metabolism in tomato.

The use of compost tea is important to improve food safety. However, the effect of compost tea on N uptake and partitioning in tomato is unclear. In this study, we measured temporal and spatial changes in nitrogen content, enzyme activities, and expression levels of nitrogen transporters genes in different organs of tomato treated with five nutrient solutions.

Psychometric properties of stigma and discrimination measurement tools for persons living with HIV: a systematic review using the COSMIN methodology.

Background: The development of antiretroviral therapy broadly extends the life expectancy of persons living with HIV (PLHIV). However, stigma and discrimination are still great threat to these individuals and the world's public health care system. Accurate and reproducible measures are prerequisites for robust results.

The effectiveness and sustainability of peer support interventions for persons living with HIV: a realist synthesis.

Background: Peer support is an important supplement to medical resources for persons living with HIV (PLHIV). However, previous studies have shown mixed results about intervention effects. It is necessary to explain the mechanism of peer support interventions' effectiveness and sustainability to help design more valid peer support interventions.

Psychometric properties of measurement tools of active aging: A systematic review.

Background: Active aging has become a global goal under the current aging situation. Accurate and reproducible assessment tools are prerequisites to robust and reliable results for prevalence evaluation, associated factor exploration, and intervention effect assessment. However, there remains no systematic review to summarize all active aging assessment tools and report their psychometric properties.

Carbon dioxide and methane fluxes from mariculture ponds: The potential of sediment improvers to reduce carbon emissions.

The CO and CH fluxes across the water-air interface were determined in two groups of swimming crab (Portunus trituberculatus)-ridgetail white prawn (Exopalaemon carinicauda) polyculture ponds. One group of ponds with sediment improver application were referred to as SAPs, and the other group receiving no sediment improver were as NSPs. During the farming season, both the SAPs and NSPs acted as CO sinks and CH sources.
