gscramble: Simulation of Admixed Individuals Without Reuse of Genetic Material.

While a best practice for evaluating the behaviour of genetic clustering algorithms on empirical data is to conduct parallel analyses on simulated data, these types of simulation techniques often involve sampling genetic data with replacement. In this paper we demonstrate that sampling with replacement, especially with large marker sets, inflates the perceived statistical power to correctly assign individuals (or the alleles that they carry) back to source populations-a phenomenon we refer to as resampling-induced, spurious power inflation (RISPI). To address this issue, we present gscramble, a simulation approach in R for creating biologically informed individual genotypes from empirical data that: (1) samples alleles from populations without replacement and (2) segregates alleles based on species-specific recombination rates.

Probing ligand-induced conformational changes in an MFS transporter in vivo using site-directed PEGylation.

So far, site-directed alkylation (SDA) studies on transporters in the Major Facilitator Superfamily (MFS) are mostly performed at conditions different from the native cellular environment. In this study, using GFP-based site-directed PEGylation, ligand-induced conformational changes in the lactose permease of Escherichia coli (LacY), were examined in vivo for the first time. Accessibility/reactivity of single-Cys replacements in a Cys-less LacY-eGFP fusion background was tested using methoxy polyethylene glycol-maleimide-5K (mPEG-Mal-5K) in the absence or presence of a ligand, and the band-shift of the fusion upon PEGylation was detected by in-gel fluorescence.

Reduced CAR T expansion post infusion is associated with poor survival in patients with large B cell lymphoma after two or more therapies.

CD19 directed chimeric antigen receptor (CAR) T-cell therapy is now standard of care for relapsed/refractory large B-cell non-Hodgkin lymphoma. Despite good overall response rates, many patients still experience disease progression and therefore it is important to predict those at risk of relapse following CAR T-cell therapy. We performed a prospective study using a flow cytometric assay at a single treatment centre to assess early CAR T-cell expansion in vivo 6 - 9 days after CAR-T cell infusion.

Meaningful Patient Participation in Health Care Education: A Theoretically Informed Study Exploring Boundaries and Identities.

Purpose: After recent policy and practice changes, health care schools are expected to involve patients as partners in the management, design, and delivery of professional curricula. However, what these partnerships mean for academic communities and the processes needed to support them are not yet understood. This study examines what involving patients as partners within an academic community means for key stakeholders.
