Framing Later Life Vulnerability during the COVID-19 Pandemic: A Content Analysis of Newspaper Coverage in Canada and the United States.

This study explores vulnerability narratives used in relation to older adults and others during the COVID-19 pandemic. A mixed-method content analysis was conducted of 391 articles published in two major newspapers in Canada and the USA during the first wave of the pandemic. The findings indicated that during the early months of the pandemic, limited attention was directed towards its impact on older adults or other 'vulnerable' subpopulations in both countries.

Film Coatings Based on Aqueous Shellac Ammonium Salt "Swanlac ASL 10" and Inulin for Colon Targeting.

Over the past decades, increasing interests took place in the realm of drug delivery systems. Beyond treating intestinal diseases such as inflammatory bowel disease, colon targeting can provide possible applications for oral administration of proteins as well as vaccines due to the lower enzymatic activity in the distal part of GIT. To date, many strategies are employed to reach the colon.

Mental Health Benefits and Detriments of Caregiving Demands: A Nonlinear Association in the Canadian Longitudinal Study on Aging.

Objectives: This study examines whether the association between caregiving demands and mental health is non-linear and also, whether this non-linear association is contingent on the marital status of the caregiver.

Methods: We analyze the data from the Canadian Longitudinal Study on Aging, applying OLS regression and quadratic interaction terms.

Results: A lower level of demands is salubriously associated with symptoms of depression and life satisfaction, but this association becomes deleterious at higher levels of demands.

Serological Hendra Virus Diagnostics Using an Indirect ELISA-Based DIVA Approach with Recombinant Hendra G and N Proteins.

Since the identification of Hendra virus (HeV) infections in horses in Australia in 1994, more than 80 outbreaks in horses have been reported, and four out of seven spillover infections in humans had a fatal outcome. With the availability of a subunit vaccine based on the HeV-Glycoprotein (HeV-G), there is a need to serologically ifferentiate the nfected from the accinated nimals (DIVA). We developed an indirect ELISA using HeV-G expressed in and HeV-Nucleoprotein (HeV-N) expressed in recombinant baculovirus-infected insect cells as antigens.

Physical Properties of Shellac Material Used for Hot Melt Extrusion with Potential Application in the Pharmaceutical Industry.

Hot melt extrusion offers an efficient way of increasing the solubility of a poorly soluble drug. Shellac has potential as a pharmaceutical matrix polymer that can be used in this extrusion process, with further advantages for use in enteric drug delivery systems. The rheological property of a material affects the extrusion process conditions.
