Cell entry by enveloped viruses involves a set of multistep, multivalent interactions between viral and host proteins as well as manipulation of nanoscale membrane mechanics by these interacting partners. A mechanistic understanding of these events has been challenging due to the complex nature of the interactions and the event-to-event heterogeneity involved. Single-virus microscopy has emerged as a powerful technique to probe viral binding and fusion kinetics.

Background: Monkeypox (Mpox) is a re-emerging zoonotic disease with limited therapeutic options, necessitating the exploration of novel antiviral agents. (turmeric) is a widely used medicinal plant known for its antioxidant and anti-inflammatory properties, primarily attributed to its bioactive curcuminoids.
Aim: This study aimed to evaluate the therapeutic potential of aqueous extract (CAE) against monkeypox through phytochemical characterization, biological assays, and computational analyses.

Although membrane technology is widely used in different gas separation applications, membrane manufacturers need to reduce the environmental impact during the membrane fabrication process within the framework of the circular economy by replacing toxic solvents, oil-based polymers, and such by more sustainable alternatives. These include environmentally friendly materials, such as biopolymers, green solvents, and surfactant free porous fillers. This work promotes the use of environmentally sustainable and low toxic alternatives, introducing the novel application of cellulose acetate (CA) as a biopolymer in combination with dimethyl carbonate (DMC) as a greener solvent and different inorganic fillers (Zeolite-A, ETS-10, AM-4 and ZIF-8) prepared without the use of toxic solvents or reactants.

Bacterial resistance, primarily stemming from misdiagnosis, misuse, and overuse of antibacterial medications in humans and animals, is a pressing issue. To address this, we focused on developing a fluorescent probe for the detection of bacteria, with a unique feature-an exceptionally long fluorescence lifetime, to overcome autofluorescence limitations in biological samples. The polymyxin-based probe (ADOTA-PMX) selectively targets Gram-negative bacteria and used the red-emitting fluorophore azadioxatriangulenium (with a reported fluorescence lifetime of 19.

The glycocalyx is a layer of villus-like structure covering the luminal surface of vascular endothelial cells. Damage to the glycocalyx has been proven linked to the development of many diseases. However, the factors that promote damage to the glycocalyx are not fully elaborated.
