We analyse the impact on schooling outcomes of growing up in a family headed by a single mother. Growing up in a non-intact family in Germany is associated with worse outcomes in models that do not control for possible correlations between common unobserved determinants of family structure and educational performance. But once endogeneity is accounted for, whether by using sibling-difference es...

A method has been developed to isolate pure preparations of nuclei in high yield from commercially available viable rice embryos (germ), employing extraction with buffer solution containing glycerol (without detergent) and polyamine, followed by centrifugation on a 30% Percoll cushion. The intactness of the isolated nuclei was confirmed by light microscopy as well as electron microscopy. The pr...

The aim of this study was to investigate the possible role of tubulin βII, a cytoskeletal protein, in regulation of mitochondrial oxidative phosphorylation and energy fluxes in heart cells. This isotype of tubulin is closely associated with mitochondria and co-expressed with mitochondrial creatine kinase (MtCK). It can be rapidly removed by mild proteolytic treatment of permeabilized cardiomyoc...

Protected areas are highly heterogeneous in their effectiveness at buffering human pressure, which may hamper ability to conserve species sensitive activities. Here, we use 60 million bird observations from eBird estimate the sensitivity pressure of each breeding Americas. Concerningly, find that ecoregions hosting large proportions high-sensitivity species, concentrated tropical biomes, do not...

BACKGROUND In order to adapt oral care and treatment to the demands of the growing group of frail dentulous older people, it is important to understand how and to which extent having natural teeth contributes to the quality of life (QoL) of frail older people and how frailty influences their perspective. METHODS A qualitative approach was used. Interviews with 38 Dutch frail older dentulous p...

Coat protein (CP) of Hibiscus chlorotic ringspot virus (HCRSV) had been found to be responsible for the spread of infection. Kenaf (Hibiscus cannabinus) was used as a model organism in this study. As CP is most likely localized in the peroxisomes, there is a need to produce a protocol adapted solely for the isolation of peroxisomes from the leaf of Kenaf as peroxisomal characteristics differ gr...
