Pompe disease is an inherited disorder caused by disease-associated variants in the acid α-glucosidase gene (GAA). The Pompe disease GAA variant database (http//www.pompevariantdatabase.nl) is a curated, open-source, disease-specific database, and lists disease-associated GAA variants, in silico predictions, and clinical phenotypes reported until 2016. Here, we provide an update to include 226 disease-associated variants that were published until 2020. We also listed 148 common GAA sequence variants that do not cause Pompe disease. GAA variants with unknown severity that were identified only in newborn screening programs were listed as a new feature to indicate the reason why phenotypes were still unknown. NSC 641530 Expression studies were performed for common missense variants to predict their severity. The updated Pompe disease GAA variant database now includes 648 disease-associated variants, 26 variants from newborn screening, and 237 variants with unknown severity. Regular updates of the Pompe disease GAA variant database will be required to improve genetic counseling and the study of genotype-phenotype relationships.Social isolation undermines health. Inequities in social networks exist due to historical and contemporary practices of socioeconomic and racial segregation. Thus, lower income and minority families are less likely to have the number, strength, and variety of social connections as higher income and white families. Therefore, social isolation may contribute to inequities in health and well-being across socioeconomic and racial groups. Disrupting social isolation by strengthening social networks may be a meaningful way to equitably improve population health. In this study we aimed to better understand the factors that influence the formation and sustainment of social connections in neighbourhoods experiencing a disproportionate burden of social needs and poor health outcomes. Participants were recruited through our community-academic partnership, Healthy Homes (HH). Healthy Homes serves families with pregnant women and/or children less then 6 years in two low-income, high-morbidity neighbourhoods, focusing on supporting families’ needs and hopes. Between October 2016 and April 2017, we conducted in-depth qualitative interviews (n = 20) with English-speaking mothers and grandmothers of children under less then 6 years. Interviews were audio-recorded, transcribed verbatim and independently coded. After applying an a priori code list, we conducted emergent coding to identify additional themes. Themes focused on the social environment, including social connections and social isolation, among vulnerable populations in included neighbourhoods. Families want connection to one another and to resources but look to others to facilitate those connections. Families may want or need social connections but do not engage if it means sacrificing their values or sense of self-worth. These findings provide a deeper understanding of the factors that might allow us to disrupt social isolation by building relationships in communities that face social and health inequities.

To identify areas that present a higher risk of exposure to accidents with scorpions in Brazil.

We used techniques of spatial prioritisation to determine the most vulnerable localities to envenomation by four scorpion species. Our prioritisation integrated ecological niche models with health investment, antivenin availability, access to health care facilities and metrics of human impact data.

The ecological niche models indicated that three scorpion species (Tityus bahiensis, Tityus serrulatus, and Tityus stigmurus) are more associated with human population density, while T.obscurus demonstrated a strong association with temperature variations during the year. Spatial prioritisation indicated that the areas with higher risk exposure to accidents with scorpions are in northern and northeastern Brazil. Alternatively, more isolated but densely populated areas in the southeastern and central regions also emerged as a priority.

Mapping areas where humans are more likely to interact with scorpions can assist in the design of efficient public health policies.

Previous studies have shown that a small molecule compound (W2476) was able to improve β-cell dysfunction and exert therapeutic effects in diabetic mice via repression of TXNIP signaling pathway. The impact of W2476 on TXNIP transcription was thus investigated using the chromatin immunoprecipitation method. It was found that W2476 promotes competitive binding of forkhead box O1 transcription factor (FOXO1) to the carbohydrate response element (ChoRE) sequence associated with ChoRE-binding protein (ChREBP)/Mlx interacting protein-like(Mlx) complexes. This interaction hinders the attachment of histone acetyltransferase p300 and reduces histone H4 acetylation on the TXNIP promoter, leading to decreasing TXNIP transcription.Monodisperse unilamellar nanotubes (NTs) and nanoribbons (NRs) were transformed to multilamellar NRs and NTs in a well-defined fashion. This was done by using a step-wise approach in which self-assembled cationic amino acid amphiphile (AAA) formed the initial NTs or NRs, and added polyanion produced an intermediate coating. Successive addition of cationic AAA formed a covering AAA layer, and by repeating this layer-by-layer (LBL) procedure, multi-walled nanotubes (mwNTs) and nanoribbons were formed. This process was structurally investigated by combining small-angle neutron scattering (SANS) and cryogenic-transmission electron microscopy (cryo-TEM), confirming the multilamellar structure and the precise layer spacing. In this way the controlled formation of multi-walled suprastructures was demonstrated in a simple and reproducible fashion, which allowed to control the charge on the surface of these 1D aggregates. This pathway to 1D colloidal materials is interesting for applications in life science and creating well-defined building blocks in nanotechnology.
