Congenital microcephaly occurs in utero during Zika virus (ZIKV) infection. The single-gene disorder, Majewski osteodysplastic primordial dwarfism type II (MOPDII), also leads to microcephaly and is concomitant with a decrease in the centrosomal protein, pericentrin (PCNT). This protein is a known contributor of mitotic spindle misorientation and u...
Os invertebrados bentônicos são importantes, tanto em ecossistemas lóticos como lênticos, por conta da contribuição ecológica na ciclagem de nutrientes, na passagem do fluxo de energia pelos níveis tróficos. Este trabalho teve por objetivo verificar a composição da comunidade de invertebrados bentônicos e caracterizar os respectivos grupos tróficos...
A região Neotropical possui uma rica fauna de esponjas de água doce, porém o conhecimento sobre sua taxonomia, bem como sobre as comunidades dentro delas permanece fragmentado. Larvas de Chironomidae (Insecta, Diptera) associadas a esponjas de água doce têm sido amplamente relatadas na literatura, com alguns gêneros que são reconhecidos como conten...
Variações polimórficas podem atuar nas alterações cromáticas, que, em excesso, causam a hiperpigmentação (indivíduos melânicos), e quando deficientes são responsáveis pela hipopigmentação (indivíduos albinos, leucísticos ou com piebaldismo) e podem estar associadas com aspectos ecológicos, fisiologia e outros processos biológicos. No Brasil, o leuc...
Scandinavia was one of the last geographic areas in Europe to become habitable for humans after the Last Glacial Maximum (LGM). However, the routes and genetic composition of these postglacial migrants remain unclear. We sequenced the genomes, up to 57x coverage, of seven hunter-gatherers excavated across Scandinavia and dated from 9,500-6,000 year...
In cities today, vast amounts of nutrients are being wasted. Improvement in nutrient management within agriculture can contribute to a more sustainable society. Reusing nutrients in agriculture could aid in creating a more circular system, where organic fertilizers can be used instead of chemical fertilizers. Urine is a liquid which has a high nutr...
Male and female plants of dioecious species often experience differential herbivory, possibly due to differences in defences such as secondary metabolite composition or nutritional quality. These plant sex effects on herbivory have been extensively studied for plant individuals, but not for stands/populations. For mobile herbivores, such as deer, s...
Sediments underlying hypoxic or anoxic water bodies constitute a net source of phosphorus to the bottom water. This source has the potential to enhance eutrophication. Benthic fluxes of dissolved phosphorus, iron and manganese were measured from hypoxic, normoxic, and normoxic bioturbated by the invasive polychaete Marenzelleria arctia sediment in ...
Syftet med denna studie är att ta reda på hur de tre dimensionerna av hållbar utveckling förekommer i elevernas uppfattningar av begreppet, samt vilka aspekter av dimensionerna som kan kopplas till elevernas uppfattningar. Studiens frågeställningar har undersökts med hjälp av kvalitativa intervjuer. Empiri har samlats in under fyra intervjuer av se...
Abstract Introduction Failure in the mechanism of self-tolerance in T or B cells can lead to autoimmunity. One of the autoimmune diseases is rheumatoid arthritis (RA), which is a chronic inflammatory disease of unknown cause and is characterized by systemic inflammation, autoantibodies and joint destruction. Serology is crucial for the classificati...
