Community gardens and urban agriculture: Healthy environment/healthy citizens.

Int J Ment Health Nurs

December 2023

Student Department of Nursing, MacEwan University, Edmonton, Alberta, Canada.

Studies are showing that urban community gardening can improve people's psychological and physiological health in myriad ways. Community gardens increase social capital, provide opportunities for altruism, and create accessible and sustainable food sources in urban environments. The purpose of this study was to explore the mental, social, and physical health benefits of participation in an urban community garden in Edmonton, Canada.

Spousal bereavement poses considerable challenges to adults in late life. Some populations, such as older immigrants, may experience heightened negative outcomes as a consequence of spousal bereavement, due to migratory stress and social isolation. Spousal bereavement is culturally embedded as it is related to cultural beliefs and attitudes concerning death and family relationships.

Objective: Older Muslim immigrants experience multiple vulnerabilities living in Canada. This study explores the experiences of Muslim older adults during the COVID-19 pandemic to identify ways to build community resilience as part of a community-based participatory research partnership with a mosque in Edmonton, Alberta.

Methods: Using a mixed-methods approach, check-in surveys (n = 88) followed by semi-structured interviews (n = 16) were conducted to assess the impact of COVID-19 on older adults from the mosque congregation.

Each cerebellar hemisphere projects to the contralateral cerebral hemisphere. Previous research suggests a lateralization of cognitive functions in the cerebellum that mirrors the cerebral cortex, with attention/visuospatial functions represented in the left cerebellar hemisphere, and language functions in the right cerebellar hemisphere. Although there is good evidence supporting the role of the right cerebellum with language functions, the evidence supporting the notion that attention and visuospatial functions are left lateralized is less clear.

Background: Public safety personnel experience various mental health conditions due to their work's complex and demanding nature. There are barriers to seeking support and treatment; hence, providing innovative and cost-effective interventions can help improve mental health symptoms in public safety personnel.

Objective: The study aimed to evaluate the impact of Text4PTSI on depression, anxiety, trauma, and stress-related symptoms, and the resilience of public safety personnel after six months of providing supportive text message intervention.

This study assessed the sensitivity of four anxiety-like behaviour paradigms in zebrafish: the novel tank dive test, shoaling test, light/dark test, and the less common shoal with novel object test. A second goal was to measure the extent to which the main effect measures are related to locomotor behaviours to determine whether swimming velocity and freezing (immobility) are indicative of anxiety-like behaviour. Using the well-established anxiolytic, chlordiazepoxide, we found the novel tank dive to be most sensitive followed by the shoaling test.

A mechanically robust in-tube stainless steel microneedle solid phase microextraction (SPME) platform for dual electrochemical and chromatographic detection has been demonstrated. The SPME microneedle was fabricated by layer-by-layer (LbL) in-tube coating, consisting of carbon nanotube (CNT)/cellulose nanocrystal (CNC) film layered with an electrically conductive polyaniline (PANI) hydrogel layer (PANI@CNT/CNC SPME microneedle (MN)). The PANI@CNT/CNC SPME MN showed effective analysis of caffeine by GC-MS with an LOD of 26 mg/L and excellent precision across the dynamic range.

Department of Civil and Environmental Engineering, University of Alberta, Edmonton, AB T6G 1H9, Canada. Electronic address:

Microplastic (MP) disks have not been studied for settling behaviors in aquatic environments, which affects the transport and fate of MPs. Therefore, settling experiments were conducted on MP disks of three shapes and four common-seen materials. Lighter MP disks (with density ρ = 1.

The value of team-based learning in a pandemic and five simple tips to get started.

Biochem Mol Biol Educ

May 2023

Department of Biological Sciences, MacEwan University, Edmonton, Canada.

Team-Based Learning (TBL) can be easily applied to different learning outcomes in various courses. This approach builds community and provides peer support for students in both in-person and online learning environments. When used for formative assessment, it can promote student learning while reducing the quantity of grading for instructors.

Aquatic species are capable of detecting infrasound (sub-20 Hz frequencies) which may be a source of anthropogenic pollution and have a detrimental impact on the environmental fitness of fish. Infrasound is generated by infrastructure, producing acoustic frequency peaks that are not discernible by humans. The presence of these frequencies may therefore impact the environmental wellbeing of aquatic laboratory animals, which are often housed in spaces adjacent to facilities producing infrasound.

Hydrovoltaic Nanogenerators for Self-Powered Sweat Electrolyte Analysis.

Small

April 2023

State Key Laboratory of Electroanalytical Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun, 130022, P. R. China.

Human sweat comprises various electrolytes that are health status indicators. Conventional potentiometric electrolyte sensors require an electrical power source, which is expensive, bulky, and requires a complex architecture. Herein, this work demonstrates an electric nanogenerator fabricated using silicon nanowire (SiNW) arrays comprising modified carbon nanoparticles.

Electron Conductive and Transparent Hydrogels for Recording Brain Neural Signals and Neuromodulation.

Adv Mater

March 2023

State Key Laboratory of Electroanalytical Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun, 130022, P. R. China.

Recording brain neural signals and optogenetic neuromodulations open frontiers in decoding brain neural information and neurodegenerative disease therapeutics. Conventional implantable probes suffer from modulus mismatch with biological tissues and an irreconcilable tradeoff between transparency and electron conductivity. Herein, a strategy is proposed to address these tradeoffs, which generates conductive and transparent hydrogels with polypyrrole-decorated microgels as cross-linkers.

Multiple Sclerosis (MS) is an autoimmune disease with notable sex differences. Women are not only more likely to develop MS but are also more likely than men to experience neuropathic pain in the disease. It has been postulated that neuropathic pain in MS can originate in the peripheral nervous system at the level of the dorsal root ganglia (DRG), which houses primary pain sensing neurons (nociceptors).

A portable, molecularly imprinted polymer (MIP)-based microneedle (MN) sensor for the electrochemical detection of imidacloprid (IDP) has been demonstrated. The MN sensor was fabricated via layer-by-layer (LbL) in-tube coating using a carbon nanotube (CNT)/cellulose nanocrystal (CNC) composite, and an IDP-imprinted polyaniline layer co-polymerized with imidazole-functionalized CNCs (PANI-co-CNC-Im) as the biomimetic receptor film. The sensor, termed MIP@CNT/CNC MN, was analyzed using both cyclic voltammetry (CV) and differential pulse voltammetry (DPV) and showed excellent electrochemical performance for the detection of IDP.

Using a standardized, validated risk assessment tool is an integral part of risk management and should be employed to evaluate a youth who is at risk to and/or has engaged in sexually abusive behaviors. Risk and needs tools are needed to inform critical decisions about the allocation of services and the areas that should be targeted in treatment and supervision. Although practitioners have a number of published tools to their avail, it is often less practical to discover the type of tool, where to access the tool, information regarding its psychometric properties, and how to access relevant training.
