The Yin and Yang of How N-Terminal Acyl Caps Affect Collagen Triple Helices.

N-terminal acylation is a common tool for the installation of functional moieties (e.g., sensors or bioactive molecules) on collagen model peptides (CMPs).

Predicting Collagen Triple Helix Stability through Additive Effects of Terminal Residues and Caps.

Collagen model peptides (CMPs) consisting of proline-(2S,4R)-hydroxyproline-glycine (POG) repeats have provided a breadth of knowledge of the triple helical structure of collagen, the most abundant protein in mammals. Predictive tools for triple helix stability have, however, lagged behind since the effect of CMPs with different frames ([POG] , [OGP] , or [GPO] ) and capped or uncapped termini have so far been underestimated. Here, we elucidated the impact of the frame, terminal functional group and its charge on the stability of collagen triple helices.

An observational study of personal and environmental factors associated with attendance at a community-based adaptive fitness center for adults with physical disabilities.

Background: Regular exercise has many benefits for adults with physical disabilities (AwPD). Despite these benefits, significant barriers to participating in exercise exist for AwPD. Community-based adaptive fitness centers promote exercise for AwPD by minimizing barriers.

Aging with Disability Symptoms and Ability to Participate in, and Satisfaction with, Social Participation among Persons Aged 45-64.

Pain, fatigue, and depression, considered aging with disability (AwD) symptoms, are known to be substantially higher among middle-aged adults with long-term disability compared to their age peers. Participation has been recognized as an important component of health. This cohort survey study reports findings on the relationship between AwD symptoms and ability to participate in, and satisfaction with participation in, social roles and activities using PROMIS measures.

Impact of the COVID-19 Pandemic on Psychosocial Health of Persons With Spinal Cord Injury: Investigation of Experiences and Needed Resources.

Background: Emerging evidence suggests that the COVID-19 pandemic has been accompanied by increased rates of depression and social isolation. However, we do not yet understand how the COVID-19 pandemic has affected the psychosocial health of people with spinal cord injury (PwSCI), a population that is already at risk of experiencing mental health conditions.

Objectives: The aims of the study were to (1) examine the impact of the pandemic on the psychosocial health of PwSCI and (2) investigate the experiences of PwSCI and resources they reported needing during the peak of the pandemic.
