Intracellular microorganisms like viruses and bacteria impact immune cell function. However, detection of these microbes is challenging as the majority exist in a non-culturable state. This protocol presents detailed steps to investigate intracellular microbial diversity using single-cell RNA sequencing (scRNA-seq) in immune-cells of SARS-CoV-2-positive and recovered patients.

Acute lung injury (ALI) and its severe form, acute respiratory distress syndrome (ARDS), is a clinical syndrome that can cause pulmonary edema, inflammation, oxidative stress, and immunological dysregulations. β-Caryophyllene (BCP), a natural bicyclic sesquiterpene, possesses a variety of pharmacological properties and has the potential to be a therapeutic agent. This study aimed to comprehend the effect of BCP on Nrf2/HO-1/NF-κB and ACE2/MasR axis in a rat model of ALI by lipopolysaccharide (LPS) and the underlying mechanisms during this process.

The functionality of natural origin-based fibres can provide minimal protection against UV exposure; however, surface modification of fabrics can help to achieve better outcomes. The ability to provide protection basically depends upon several factors of textile fabric, such as fibre chemistry, yarn structural parameters, fabric weave construction, fabric areal density, cover factor, porosity, and humidity. Due to the constant reduction of the ozone layer in the atmosphere, increasing UV radiation has now raised severe concerns across the globe, which is projected to deteriorate the state of global health.
