Picosecond time-resolved fluorescence of phycobiliproteins

The α- and β-subunits of C-phycocyanin from Mastigocladus laminosus were prepared according to revised procedures. Both subunits are isolated as dimers, which can be dissociated into monomers with detergent mixtures. The fluorescence decay kinetics are similar for the respective monomers and dimers. In no case could they be fitted by only one (α-subunit) or two exponentials (β-subunit) which are predicted by theory for samples with a unique chromophore—protein arrangement containing one and two chromophores, respectively. It is suggested that there exists a heterogeneity among the chromophores of the subunits, which may persist in the highly aggregated complexes present in cyanobacterial antennas

A scoping review of supports on college and university campuses for autistic post-secondary students

Given the demand to better address the principles of equity, diversity, inclusion, and accessibility in higher education, research into both barriers and promising practices to support autistic students on post-secondary campuses has advanced significantly in the last decade. The objective of this scoping review is to identify, map, and characterize literature that enumerates and describes supports for autistic post-secondary students. This scoping review was limited to peer-reviewed research published between January 2012 and May 2022, in these databases: Web of Science, PsycINFO, Medline, EMBASE, ERIC, Social Work Abstracts, Social Services Abstracts, and EMCARE. The review aligns to Joanna Briggs Institute methodology for scoping reviews and includes consultation with an expert panel made up of the Autistic Community Partners–four autistic individuals with postsecondary experience who acted as co-researchers. Literature on creating accessible campuses were mapped in three ways: (1) through the four domains of the PASS Taxonomy; (2) ten support categories characterizing types of supports, and (3) nine emergent themes, based on autistic experiences on support and campus navigation, were inductively and iteratively coded throughout process. This review summarizes both areas that have been researched and under-studied areas in the literature that act as contributors or challenges for autistic students on postsecondary campuses. It was also the first scoping review, to our knowledge, to integrate lived experience within the methods and results analysis to describe the current state of the evidence on post-secondary campuses. Mapping the literature in known and emerging categories indicated that broad categories of support are experienced variably by autistic students. Findings provide multiple avenues for future research

Patient demographics and processes of physiotherapy care in a specialized outpatient spinal cord rehabilitation program

Affiliated institutions include: Toronto Rehabilitation Institute (H. Morris, M. Verrier, J. Williams), University of Toronto (M. Verrier, J. Williams)Purpose: The purpose of this paper was to characterize the outpatient spinal cord injury (SCI) population seeking physiotherapy care, and the program currently in place for that care at a Toronto-based specialized SCI rehabilitation centre, Toronto Rehabilitation Institute Lyndhurst Centre (Lyndhurst Centre). Methods: This retrospective longitudinal study reviewed health records of patients who accessed outpatient physiotherapy services from the Spinal Cord Rehabilitation Program at Lyndhurst Centre over an 11-month period. Data were abstracted to describe patient demographics for those with traumatic (TSCI) and non -traumatic (NTSCI) SCI, as well as program characteristics. Results: The majority of patients were English-speaking males over the age of 65 from the Metropolitan Toronto area who had sustained NTSCIs, tended to have social support and relied on government funding for health services. Patients with NTSCIs had more variable and statistically significant longer wait times for admission into outpatient physiotherapy than those who those with TSCI. The number of physiotherapy treatment sessions was significantly greater for patients with TSCIs. Conclusion: The results of this study can be used to understand the characteristics of patients requiring outpatient physiotherapy services, and guide future decisions regarding program development at Lyndhurst Centre and other large urban specialized spinal cord injury (SCI) centres in Ontario
