From chickpea and lupin as dairy alternatives
Funding text This work was supported by the FCT Project PTDC/BAA-AGR/28370/2017: âBebida de proteĂna vegetal a partir de leguminosas europeias com potencial bioativoâ; and also through the research unit UID/AGR/04129/2020 â LEAF.Consumption of plant based products as dairy alternatives is increasing steeply. This diet transition can only be achieved if these products keep the nutritional value and meet consumer's sensory acceptance. This work aimed to evaluate the decrease of the âbeanyâ flavour and of raffinose, stachyose and verbascose contents in EU pulse beveragĂ©s production, and also the best lactic fermentation conditions of the beverages, towards chickpea- and lupin-based yoghurts, with rheology properties similar to the commercial soy yoghurts. The reduction of âbeanyâ volatile compounds of chickpea and lupin beverages during processing was confirmed through GCâMS analysis. Soaking and cooking processes were effective in removing flatulence sugars with almost 48% loss from the initial content in lupin beverage. The fermentation conditions at 40 °C, 12 h and 2% (w/v) of starter concentration evidenced the best viscoelastic structure and flow properties. The lupin yoghurt-type showed a similar gel structure to commercial soy yoghurt. © 2022publishersversionpublishe
Qualidade pĂłs-colheita de diferentes acessos de inhames coletados nos estados de Alagoas e Sergipe.
O inhame (Dioscorea spp.) Ă© uma hortaliça que produz tĂșberas de elevada importĂąncia socioeconĂŽmica para alimentação e agricultura familiar, principalmente na regiĂŁo Nordeste. Algumas espĂ©cies e variedades sĂŁo cultivadas comercialmente com diferentes preferĂȘncias pelos consumidores. Entretanto, apesar do gĂȘnero ser reconhecido por possuir alto valor nutricional e energĂ©tico pouco se sabe sobre os diferentes materiais cultivados. Assim, o presente trabalho teve como objetivo avaliar a qualidade pĂłs-colheita de diferentes acessos de inhames (Dioscorea spp.). Os materiais vegetais foram coletados nos estados de Alagoas e Sergipe, foram posteriormente analisados quanto a composição fĂsico-quĂmica e os dados foram submetidos a anĂĄlise estatĂstica descritiva e multivariada. Os acessos Dioscorea cayenensis e Dioscorea alata apresentaram qualidade proteica superior aos demais materiais genĂ©ticos. Ainda Dioscorea alata apresentou altos nĂveis de zinco, magnĂ©sio e potĂĄssio. De modo geral, pode-se concluir que os acessos provenientes do Estado de Alagoas apresentaram melhor qualidade nutricional, devido aos maiores teores de nutrientes, e ainda que hĂĄ pouca variabilidade genĂ©tica nos demais acessos estudados, evidenciando a necessidade de resgate desses materiais tradicionalmente utilizados nos locais de estudo e que vĂȘm desaparecendo gradativamente

Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5â7 vast areas of the tropics remain understudied.8â11 In
the American tropics, Amazonia stands out as the worldâs most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13â15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazonâs biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the regionâs vulnerability to environmental change. 15%â18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
Glycoinositolphospholipids from Leishmania braziliensis and L. infantum: Modulation of Innate Immune System and Variations in Carbohydrate Structure
The essential role of the lipophosphoglycan (LPG) of Leishmania in innate immune response has been extensively reported. However, information about the role of the LPG-related glycoinositolphospholipids (GIPLs) is limited, especially with respect to the New World species of Leishmania. GIPLs are low molecular weight molecules covering the parasite surface and are similar to LPG in sharing a common lipid backbone and a glycan motif containing up to 7 sugars. Critical aspects of their structure and functions are still obscure in the interaction with the vertebrate host. In this study, we evaluated the role of those molecules in two medically important South American species Leishmania infantum and L. braziliensis, causative agents of visceral (VL) and cutaneous Leishmaniasis (CL), respectively. GIPLs derived from both species did not induce NO or TNF-α production by non-primed murine macrophages. Additionally, primed macrophages from mice (BALB/c, C57BL/6, TLR2â/â and TLR4â/â) exposed to GIPLs from both species, with exception to TNF-α, did not produce any of the cytokines analyzed (IL1-ÎČ, IL-2, IL-4, IL-5, IL-10, IL-12p40, IFN-Îł) or p38 activation. GIPLs induced the production of TNF-α and NO by C57BL/6 mice, primarily via TLR4. Pre incubation of macrophages with GIPLs reduced significantly the amount of NO and IL-12 in the presence of IFN-Îł or lipopolysaccharide (LPS), which was more pronounced with L. braziliensis GIPLs. This inhibition was reversed after PI-specific phospholipase C treatment. A structural analysis of the GIPLs showed that L. infantum has manose rich GIPLs, suggestive of type I and Hybrid GIPLs while L. braziliensis has galactose rich GIPLs, suggestive of Type II GIPLs. In conclusion, there are major differences in the structure and composition of GIPLs from L. braziliensis and L. infantum. Also, GIPLs are important inhibitory molecules during the interaction with macrophages
