Cardiopulmonary Impact of Wildfire Smoke
As global temperatures rise, wildfires are increasingly recognized as major public health crises. Exposure to wildfire smoke is known to worsen respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD).
Precision Particles for Persistent Asthma
A promising solution for Asthma: an innovative dry powder for inhalation (DPI) designed for controlled release and prolonged lung retention.
Cold Air and Pollution: A Combined Challenge for the Airways
Exercise-induced bronchoconstriction (EIB) is a hallmark of asthma and other respiratory diseases. It occurs when vigorous physical activity triggers transient and reversible airway narrowing. Environmental factors such as cold, dry air and air pollution are known to exacerbate symptoms, particularly in athletes and individuals exercising in urban environments.
Understanding Lung Biomechanics in Asthma By Combining ex vivo With in vitro
Asthma remains a complex and multifactorial disease, with airway hyperresponsiveness to methacholine being a hallmark feature. A recent study by Rojas-Ruiz (2025) utilizes SCIREQ’s innovative physioLens (ex vivo) and flexiVent (in vivo) platforms to shed light on the interplay between lung tissue compliance and methacholine response, offering new insights into the mechanisms driving asthma pathology.
Reducing Variability in Lung Slice Analysis
A recent publication by Boucher et al (2024) streamlines this process of quantifying airway constriction in Precision Cut Lung Slices (PCLS) by using the new physioLens automated solution for physiology and image analysis. This new solution enables researchers to conduct high-throughput screening of airway constriction with unprecedented precision and efficiency.
Exploring a Novel Approach to Asthma Management: Targeting Upstream Live Cell Extrusion
Asthma, affecting over 300 million individuals globally, remains a significant health concern with a high mortality rate. Despite advancements in treatment, many patients still struggle with symptom control and recurrent attacks.
Airway Hyperreactivity in Chlorine Exposed EIB Swimmers Model
Airway hyperresponsiveness (AHR) and exercise-induced bronchoconstriction (EIB) are conditions commonly affecting high-intensity athletes such as competitive swimmers.AHR and EIB in athletes have been well defined, however, studies focusing on immunological relevance in symptom onset may prove useful in developing preventative measures.
Advantages of ALI Exposure – expoCube
Traditional submerged cell culture techniques have well-known limitations for aerosol exposure studies; for instance, the impact of exposure dilution within the media and the poor solubility/sedimentation of some exposure particles1. Air liquid interface (ALI) cultures are a technique whereby cells are grown on a microporous membrane insert, immersed in a media-containing well.
Tissue Baths in Respiratory Disease Models
Isolated tissue baths, also known as organ chambers, are tools that have been used in the discipline of pharmacology for over 150 years to evaluate tissues contractility and relaxation response upon exposure to stimuli including the addition of various agonists1. This technique was used in one of the most breakthrough scientific findings in 1980 when the endothelium pioneers, Furchgott and Zawadski, discovered the signalling molecule nitric oxide in the cardiovascular system2 for which they were awarded the 1998 Nobel Price in physiology.
Latest Advances in Preclinical SARS-CoV-2 Research
There has been incredible scientific effort and progress over the past two years geared at the protection and treatment of COVID-19. In this blog, we will highlight some significant recent advances in SARS-CoV-2 preclinical modelling, which use the inExpose to deliver inhaled target compounds and the flexiVent to characterize a full pulmonary function profile.
