The role of seed vouchers and fairs in promoting seed market development: Opportunities and limitations

This review aims to identify whether the seed voucher and SVF/DiNER model can be modified over time (e.g., 2-5 years) to build capacity within the seed sector to support the emergence of a sustainable, market-based seed system that offers quality, affordable seeds to smallholder male and female farmers. This scoping report presents a review of the wide variety of approaches that have been tested or recommended across International NGOs. These include both adjustments to the seed voucher and SVF/DiNER model itself as well as additional activities implemented alongside or in place of SVF/DiNER fairs to address market constraints and promote the emergence of alternative viable seed markets

The development of a randomised controlled trial testing the effects of an online intervention among school students at risk of suicide

BACKGROUND: Suicide-related behaviour among young people is of significant concern, yet little is known regarding the effectiveness of interventions designed to reduce risk among this population. Of those interventions that have been tested, cognitive-behavioural therapy appears to show some promise among young people with suicidal ideation. Internet-based interventions are becoming increasingly popular and have shown some effect in preventing and treating depression and anxiety in young people. However, to date there are no randomised controlled trials examining the impact of Internet-based Cognitive Behavioural Therapy among suicidal youth. METHODS/DESIGN: This is a randomised controlled trial testing the effects of Internet-based cognitive-behavioural therapy among suicidal high school students who have sought help from the school wellbeing team. The intervention comprises 8 modules of Cognitive Behavioural Therapy delivered online. The study has a staggered, two-year recruitment phase and participants are assessed at baseline, post intervention and 12 weeks later. DISCUSSION: If effective the program has the ability to be readily adapted and delivered to a range of populations in a range of settings, at relatively little cost. It can also be adapted for mobile applications. TRIAL REGISTRATION: ACTRN12613000864729. Date registered: 05/08/2013

Histopathologic findings of pulmonary acariasis in a rhesus monkeys breeding unit Aspectos histopatológicos da acaríase pulmonar em uma criação de macacos rhesus

Histological lesions in the lungs of rhesus monkeys (Macaca mulatta) related with Pneumonyssus simicola were evidenced. The most prominent pathologic alterations included numerous thin-walled cysts 1-5 mm diameter scattered throughout the lungs, bronchiolitis, peribronchiolitis where the mites were found associated with pigmented and non-pigmented materials. Our study included data from 347 rhesus monkeys submitted to necropsies during 20 years. Four adult debilitated animals were found with pulmonary acariasis which showed a very low incidence of parasite (1.2%) in the colony. Most of the published literature described as common and widespread pulmonary acariasis in Old World monkeys. The present study confirms the ubiquity of P. simicola in captive born and raised rhesus monkeys that would compromise experimental studies involving the respiratory system.<br>Foram evidenciadas lesões histológicas nos pulmões de macacos rhesus (Macaca mulatta) relacionadas ao Pneumonyssus simicola. As principais alterações incluíram numerosos cistos variando de 1-5 mm de diâmetro, com paredes finas e amplamente distribuídos nos pulmões; bronquiolite e peribronquiolite, onde os ácaros foram encontrados associados com materiais particulados pigmentados ou não. Nosso estudo incluiu dados de 347 macacos rhesus submetidos a necropsias no decorrer de 20 anos. A acaríase pulmonar foi diagnosticada em quatro animais adultos debilitados, o que representou uma incidência muito baixa do parasita (1,2%) na colônia. A literatura descreve uma alta incidência de acaríase pulmonar em macacos do Velho Mundo. O presente estudo confirma a ubiqüidade do P. simicola em macacos rhesus nascidos e manejados em cativeiro, que compromete sua utilização em estudos experimentais envolvendo o sistema respiratório

Promote flexitarian diets worldwide: Supplementary information to: Governments should unite to curb meat consumption

Marco Springmann and colleagues warn that we must shift to more plant-based ‘flexitarian’ diets if we are to reduce the food system’s projected greenhouse-gas emissions and meet the targets of the 2015 Paris Agreement (Nature 562, 519–525; 2018). We urge countries to work with the United Nations towards a global agreement on food and agriculture that promotes the adoption of such diets, which are more sustainable than meat-based diets and are backed by evidence on healthy eating. Such an agreement would be in line with findings by focus groups in the United States, China, Brazil and the United Kingdom, which indicate that governments should urgently address unsustainable meat consumption (see go.nature.com/2asd1ag). In industrial agriculture, cereals that are edible to humans are fed to animals for conversion into meat and milk. This undermines our food security: rearing livestock is efficient only if the animals convert materials we cannot consume into food we can eat. That means raising them on extensive grasslands, rotating integrated crop-livestock systems and using by-products, unavoidable food waste and crop residues as feed. Feeding animals exclusively on such materials would greatly reduce the availability and hence the consumption of meat and dairy products, as well as the use of water, energy and pesticides — thereby cutting greenhouse-gas emissions
