Velvety tree ant extract is a chemotaxis repellent for .

Ants use a range of compounds for interspecies interactions, but the neurogenetic mechanisms mediating these interactions are unclear. Here, we used chemotaxis assays with the nematode to test if ant compounds can be detected by the worm nervous system and which chemosensory neurons are required for detection. We found that avoid the extracts of velvety tree ants ( ), and this response requires and positive neurons.

Olfactory cues elicit species-specific locomotive responses in poison frog tadpoles.

Amphibian species rear their larvae in distinct environments that may influence how they respond to different sensory stimuli. Here, we investigated the olfactory-mediated locomotive responses of two poison frog species ( and ) that vary in life history strategies. We found that tadpoles spent more time near an injury cue compared to control, while tadpoles increased their movement in response to high concentrations of amino acids.

First Malian series of surgery for rheumatic valve disease: opening of the centre, clinical features and peri-operative realities.

Introduction: Over the past two decades, the incidence of acute rheumatic fever (ARF) and chronic rheumatic heart disease (RHD) have dramatically declined in wealthier regions of the world as a result of preventative programmes, improved living standards and access to cardiac surgery. Nevertheless, ARF and RHD are still public health problems in less-developed regions of the world such as Oceania, south Asia and sub-Saharan Africa.

Aim: We report on clinical, therapeutic and prognostic aspects as well as the difficulties encountered during this first series of surgery for rheumatic valve disease in Mali.

I am ready to see you now, Doctor! A mixed-method study of the Let's Discuss Health website implementation in Primary Care.

Background: Let's Discuss Health (LDH) is a website that encourages patients to prepare their health-care encounters by providing communication training, review of topics and questions that are important to them.

Objective: To describe LDH implementation during primary care (PC) visits for chronic illnesses.

Methods: Design: Descriptive mixed-method study.

Modulation of physical activity to optimize pain sensation following an intra-articular corticosteroid injection in patients with knee osteoarthritis.

Background: Intra-articular corticosteroid injection is often used to relieve pain caused by knee osteoarthritis. This study aims to assess the impact after an intra-articular corticosteroid injection treatment on objective and subjective measurement of physical function in knee osteoarthritis patients.

Methods: Fourteen patients with unilateral knee osteoarthritis participated in this open-label uncontrolled trial.

Better pain management for elders in the intensive care unit.

By 2040, there will be 70 million people older than 65 years in the United States. Approximately 50% have pain on a daily basis, and research shows that their pain is often underdiagnosed and undertreated. Nurses have an obligation to provide state-of-the-art care and advocate for vulnerable older adults in the intensive care unit (ICU).

From evidence to community practice in work rehabilitation: the Quebec experience.

Background: The causes of prolonged disability due to back pain are multiply determined, involving medical, social, and environmental factors. Possible solutions to the problem of prolonged back pain disability have emerged from recent research but few efforts have been made to transfer evidence-based programs to large community settings.

Objective: This article describes three phases of the process of transfer of evidence from rehabilitation research to community practice in the province of Quebec.
