Article Synopsis
  • Chronic stress alters cellular reactions by interfering with RNA metabolism, leading to potential contributions to disease, yet this aspect has not been widely studied.
  • Stress granules (SGs), which typically form in response to acute stress, do not assemble in cells exposed to chronic, low-dose stress conditions.
  • The study found that chronic stress slows down mRNA translation, induces ribosome stalling, and ultimately prevents the formation of SGs during subsequent acute stress scenarios.

Structure probing combined with next-generation sequencing (NGS) has provided novel insights into RNA structure-function relationships. To date, such studies have focused largely on bacteria and eukaryotes, with little attention given to the third domain of life, archaea. Furthermore, functional RNAs have not been extensively studied in archaea, leaving open questions about RNA structure and function within this domain of life.

Eldercare and places of eldercare have been radicalized with the advent of COVID-19. Growing concerns about the safety of long-term care homes, coupled with the continuation of stay-at-home orders, mean that carers are reconstructing new meanings and places of care provision. Increasingly for many Canadians, the home is rapidly becoming the nexus of one's domestic, work, and caregiving world.

Guanine-rich regions of DNA or RNA can form structures with two or more consecutive G-quartets called G-quadruplexes (GQ). Recent studies reveal the potential for these structures to aggregate in vitro. Here, we report effects of in vivo concentrations of additives-amino acids, nucleotides, and crowding agents-on the structure and solution behavior of RNAs containing GQ-forming sequences.

Article Synopsis
  • - RNA molecules have strong and redundant interactions that allow them to easily bind with each other, particularly when they don’t form strong self-structures, leading to phenomena like liquid-liquid phase separation.
  • - The article examines how RNA can create stable structures (monomers, dimers, etc.) based on its length and sequence, considering the intrinsic properties that drive these formations across various biological contexts.
  • - Environmental stresses in plants, such as temperature changes and drought, can influence RNA behaviors, potentially regulating the formation of RNA-rich compartments that play a role in biological processes and responses.

G-Quadruplexes (GQs) are compact, stable structures in DNA and RNA comprised of two or more tiers of quartets whose G-rich motif of tracts of two or more G's occurs commonly within genomes and transcriptomes. While thermodynamically stable , these structures remain difficult to study . One approach to understanding GQ behavior is to test whether conditions and molecules found in cells facilitate their folding.

Background: Current Canadian evidence illustrating the health benefits and cost-effectiveness of caregiver-friendly workplace policies is needed if Canadian employers are to adopt and integrate caregiver-friendly workplace policies into their employment practices. The goal of this three-year, three study research project is to provide such evidence for the auto manufacturing and educational services sectors. The research questions being addressed are: What are the impacts for employers (economic) and workers (health) of caregiver-friendly workplace policy intervention(s) for full-time caregiver-employees? What are the impacts for employers, workers and society of the caregiver-friendly workplace policy intervention(s) in each participating workplace? What contextual factors impact the successful implementation of caregiver-friendly workplace policy intervention(s)?

Methods: Using a pre-post-test comparative case study design, Study A will determine the effectiveness of newly implemented caregiver-friendly workplace policy intervention(s) across two workplaces to determine impacts on caregiver-employee health.

In 2010, Castleden and colleagues published a paper in this journal using the concept of 'place' as an analytic tool to understand the nature of palliative care provision in a rural region in British Columbia, Canada. This publication was based upon pilot data collected for a larger research project that has since been completed. With the addition of 40 semi-structured interviews with users and providers of palliative care in four other rural communities located across Canada, we revisit Castleden and colleagues' (2010) original framework.

Background: Much of what is known about family caregiving at end-of-life in Canada has been studied within the context of various disease categories or across different care settings, rather than in relation to specific ethnic/cultural identities. Such homogeneity belies the impact of cultural and social factors on the experiences and outcomes of palliative and end-of-life (P/EOL) care. We know little about the end-of-life experiences of Vietnamese-Canadian families.

This is the second in a series of papers that deal with care-giving in Canada, as based on data available from the Canadian General Social Survey (2007). Building on the first paper, which reviewed the differences between short-term, long-term and end-of-life (EOL) caregivers, this paper uniquely examines the caregiver supports employed by EOL caregivers when compared to non-EOL caregivers (short-term and long-term caregivers combined). Both papers employ data from Statistics Canada's General Social Survey (GSS Cycle 21: 2007).

The objective of this study was to examine how Vietnamese family caregivers (FCGs) perceive, manage and experience end-of-life care-giving for seriously ill family members. Using an instrumental case study design, this longitudinal qualitative research employed the use of cultural brokers/language interpreters to help ensure that the research was conducted in a culturally-appropriate manner. Participants (n = 18) discussed their experiences of care-giving within the context of a traditional cultural framework, which was found to influence their motivations and approaches to care-giving, as well as their propensities towards the use of various supports and services.

The Compassionate Care Benefit was implemented in Canada in 2004 to support employed informal caregivers, the majority of which we know are women given the gendered nature of caregiving. In order to examine how this policy might evolve over time, we examine the evolution of a similar employment insurance program, Canada's Maternity Leave Benefit. National media articles were reviewed (n = 2,698) and, based on explicit criteria, were analyzed using content analysis.

Using data from Statistic Canada's General Social Survey Cycle 21 (GSS 2007), this study explores whether differences exist in the impacts of care-giving among three groups of caregivers providing informal care either in the caregiver's or recipient's home, or in other locations within the community: (i) those providing end-of-life (EOL) care (n = 471); (ii) those providing long-term care (more than 2 years) for someone with a chronic condition or long-term illness (n = 2722); and (iii) those providing short-term care (less than 2 years) for someone with a chronic condition or long-term illness (n = 2381). This study lays out the variation in sociodemographic characteristics across the three caregiver groups while also building on our understanding of the differential impacts of care-giving through an analysis of determinants. All three groups of caregivers shared a number of sociodemographic characteristics, including being female, married, employed and living in a Census Metropolitan Area (CMA).

Background: This paper focuses on the sustainability of existing palliative care teams that provide home-based care in a shared care model. For the purposes of this study, following Evashwick and Ory (2003), sustainability is understood and approached as the ability to continue the program over time. Understanding factors that influence the sustainability of teams and ways to mitigate these factors is paramount to improving the longevity and quality of service delivery models of this kind.

Article Synopsis
  • Palliative and end-of-life (P/EOL) care is a growing public health issue in Canada, and informal caregivers often face negative impacts on their well-being while providing this care.
  • The study uses interviews from 57 Canadian caregivers to evaluate the effectiveness of the Compassionate Care Benefit (CCB) in addressing the burdens faced by these caregivers and compares the findings to the population health promotion (PHP) model.
  • Results indicate that the CCB falls short of meeting the needs of caregivers, as it does not adequately address key determinants of health, such as gender, social support, and income, which contribute to caregiver burden.

Background: An aging population, rise in chronic illnesses, increase in life expectancy and shift towards care being provided at the community level are trends that are collectively creating an urgency to advance hospice palliative care (HPC) planning and provision in Canada. The purpose of this study was to analyze the evolution of HPC in seven provinces in Canada so as to inform such planning and provision elsewhere. We have endeavoured to undertake this research out of awareness that good future planning for health and social care, such as HPC, typically requires us to first look backwards before moving forward.

Background: Hope is defined by caregivers as the inner strength to achieve future good and to continue care giving. Pilot test findings of a Living with Hope Program (LWHP) suggested it is an acceptable and feasible intervention for use by family caregivers. Although it shows promise in potentially increasing hope and quality of life, further testing and development is needed.

The purpose of this study was reactivation and adaptation of a strain of Plasmodium vivax to Aotus nancymai monkeys. A need arose for malarial parasites for use in serologic and molecular studies and for teaching slides. This particular strain of parasite had been characterized previously as producing high-density parasitemia in splenectomized New World monkeys and therefore represented a good candidate for reactivation.
