Integrating Urban Land Tenure Security in Health Determinants: The Design of Indicators for Measuring Land Tenure Security and Health Relationships in Developing Country Contexts.

Both urban land tenure insecurity and poor urban health outcomes are research topics of urban geographers and health experts. However, health outcomes or patterns are hardly measured in relation to land tenure security. There are no clear measures or indicators of if and how these two issues interrelate and which type of land tenure deficiency is likely to lead to which kind of health outcomes or patterns.

Improvement of subsoil physicochemical and microbial properties by short-term fallow practices.

Fallow management can improve the soil nutrients in the topsoil and upper subsoil. However, little is known about the effects of short-term (one year) fallowing with different treatments, such as vegetation and fertilization, on subsoil (20-40 cm) properties. We conducted field trials to explore the changes in subsoil properties in response to such treatments in the Yellow River Delta region in China.

Why Tenure Responsive Land-Use Planning Matters: Insights for Land Use Consolidation for Food Security in Rwanda.

Land use consolidation aims to address food insecurity challenges in Rwanda. However, there is contradictory evidence on whether this tool has met food security objectives or not. This study addresses two questions: How has the land use consolidation improved (or not improved) food security at the local level? How can food security challenges be addressed using a renewed approach to land use consolidation that adopts a tenure responsive land use planning procedure? We investigate these questions in Nyange Sector (in the Musanze District) of Rwanda using mixed research methods.

Differential RNA silencing suppression activity of NS1 proteins from different influenza A virus strains.

The NS1 gene of influenza A virus encodes a multi-functional protein that plays an important role in counteracting cellular antiviral mechanisms such as the interferon (IFN), protein kinase R and retinoic acid-inducible gene product I pathways. In addition, NS1 has recently been shown to have RNA interference (RNAi) or RNA silencing suppression (RSS) activity. This study analysed the IFN antagonistic activity of NS1 and the RSS activity for several influenza subtypes: H1N1, H3N2, H5N1 and H7N7.

The NS3 protein of rice hoja blanca virus complements the RNAi suppressor function of HIV-1 Tat.

The question of whether RNA interference (RNAi) acts as an antiviral mechanism in mammalian cells remains controversial. The antiviral interferon (IFN) response cannot easily be distinguished from a possible antiviral RNAi pathway owing to the involvement of double-stranded RNA (dsRNA) as a common inducer molecule. The non-structural protein 3 (NS3) protein of rice hoja blanca virus (RHBV) is an RNA silencing suppressor (RSS) that exclusively binds to small dsRNA molecules.

RNAi suppressors encoded by pathogenic human viruses.

RNA silencing or RNAi interference (RNAi) serves as an innate antiviral mechanism in plants, fungi and animals. Human viruses, like plant viruses, encode suppressor proteins or RNAs that block or modulate the RNAi pathway. This review summarizes the mechanisms by which pathogenic human viruses affect the RNAi pathway.

The Ebola virus VP35 protein is a suppressor of RNA silencing.

RNA silencing or interference (RNAi) is a gene regulation mechanism in eukaryotes that controls cell differentiation and developmental processes via expression of microRNAs. RNAi also serves as an innate antiviral defence response in plants, nematodes, and insects. This antiviral response is triggered by virus-specific double-stranded RNA molecules (dsRNAs) that are produced during infection.
