Flow inside a bone scaffold: Visualization using 3D phase contrast MRI and comparison with numerical simulations.

J Biomech 2021 Jul 12;126:110625. Epub 2021 Jul 12.

Department of Mechanical and Industrial Engineering, University of Massachusetts, Amherst, MA, USA. Electronic address:

We report on results of experimental flow measurements inside a bone scaffold model, subjected to a uniform incoming flow (applied perfusion). Understanding the flow behavior inside a tissue engineered scaffold is essential for mechanistic studies of mechanobiology, particularly flow-sensitive bone cells. Nearly all existing studies that quantify interstitial flow inside engineered bone scaffolds have been based on numerical results, in part due to the difficulties associated with quantitative measurements and visualization of flow inside large, opaque bone or bone mimics.

Timing, duration, and differential susceptibility to early life adversities and cardiovascular disease risk across the lifespan: Implications for future research.

Prev Med 2021 Jul 19:106736. Epub 2021 Jul 19.

Department of Psychology, University of Denver, Denver, CO, United States of America.

Early life adversities (ELA), include experiences such as child maltreatment, household dysfunction, bullying, exposure to crime, discrimination, bias, and victimization, and are recognized as social determinants of cardiovascular disease (CVD). Strong evidence shows exposure to ELA directly impacts cardiometabolic risk in adulthood and emerging evidence suggests there may be continuity in ELA's prediction of cardiometabolic risk over the life course. Extant research has primarily relied on a cumulative risk framework to evaluate the relationship between ELA and CVD. Read More

J Control Release 2021 Jul 19. Epub 2021 Jul 19.

Institute of Inorganic Chemistry, Department of Chemistry, , University of Cologne, Greinstraße 6, 50939 Cologne, Germany.

The coronavirus disease-19 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) has taken the world by surprise. To date, a worldwide approved treatment remains lacking and hence in the context of rapid viral spread and the growing need for rapid action, drug repurposing has emerged as one of the frontline strategies in the battle against SARS-CoV2. Repurposed drugs currently being evaluated against COVID-19 either tackle the replication and spread of SARS-CoV2 or they aim at controlling hyper-inflammation and the rampaged immune response in severe disease.

Narrative frames as choice over structure of American Indian sexual and reproductive health consequences of historical trauma.

Sociol Health Illn 2021 Jul 22. Epub 2021 Jul 22.

Montana State University, Bozeman, Montana, USA.

Emerging evidence suggests that the historical trauma associated with settler colonialism affects the sexual and reproductive health (SRH) of American Indian (AI) communities today. This article examines how one AI community narratively frames the influence of historical trauma within the context of community-based participatory research (CBPR) and the implications of this framing for health behaviours, internalized oppression, SRH outcomes, and future CBPR interventions. We found that AIs framed the SRH consequences of historical trauma with renderings that favoured personal choice over structural explanations. Read More

Donor orientation and service quality: Key factors in active blood donors' satisfaction and loyalty.

PLoS One 2021 22;16(7):e0255112. Epub 2021 Jul 22.

Department of Business Economics, Faculty of Legal and Business Sciences, Universidad Rey Juan Carlos, Madrid, Spain.

Faced with the increasing demand for blood and greater restrictions on ensuring the safety of transfusions, voluntary donation is currently the only and best alternative for the health system to have a sustainable and safe blood supply. In this context, one of the primary strategies of blood transfusion centres is to increase the satisfaction of their active donors so that they maintain their intention to donate in the future and, in turn, make the necessary recommendations so that third parties can become new donors. That is why this paper raises a question for research concerning, what should the premises be to guide the management of blood transfusion centres to maintain and even increase the satisfaction and loyalty of their active donors? In order to respond to this issue, a change in paradigm is proposed based on a management model supported by donor orientation and service quality as basic pillars, as well as on the development of a number of key social capital resources that explain this orientation toward the donor.

Induction of a chromatin boundary in vivo upon insertion of a tad border.

PLoS Genet 2021 Jul 22;17(7):e1009691. Epub 2021 Jul 22.

Department of Genetics and Evolution, Faculty of Science, University of Geneva, Geneva, Switzerland.

Mammalian genomes are partitioned into sub-megabase to megabase-sized units of preferential interactions called topologically associating domains or TADs, which are likely important for the proper implementation of gene regulatory processes. These domains provide structural scaffolds for distant cis regulatory elements to interact with their target genes within the three-dimensional nuclear space and architectural proteins such as CTCF as well as the cohesin complex participate in the formation of the boundaries between them. However, the importance of the genomic context in providing a given DNA sequence the capacity to act as a boundary element remains to be fully investigated. Read More
