E. coli and S. aureus resist silver nanoparticles via an identical mechanism, but through different pathways.

Nanostructured materials with antibacterial activity face the same threat as conventional antibiotics - bacterial resistance, which reduces their effectiveness. However, unlike antibiotics, research into the emergence and mechanisms of bacterial resistance to antibacterial nanomaterials is still in its early stages. Here we show how Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli bacteria develop resistance to silver nanoparticles, resulting in an increase in the minimum inhibitory concentration from 1.

Sofosbuvir Polymorphs Distinguished by Linearly and Circularly Polarized Raman Microscopy.

Most currently marketed pharmaceuticals are manufactured in the solid state, where the bioavailability of the active pharmaceutical ingredient (API) can be optimized through different polymorphs, cocrystals, solvates, or salts. Efficient techniques are needed to monitor the structure of pharmaceuticals during production. Here, we explore the potential of linearly and circularly polarized Raman microscopy for distinguishing three polymorphs of sofosbuvir, an antiviral drug used to treat hepatitis C.

Amides of moronic acid and morolic acid with the tripeptides MAG and GAM targeting antimicrobial, antiviral and cytotoxic effects.

A series of amides of selected plant triterpenoids, moronic acid and morolic acid, with the tripeptides MAG and GAM, was designed and synthesized. Two required tripeptides 5 and 10 were synthesized by a step-wise chain elongation of the ethyl esters of either glycine or l-methionine at their N-terminus using Boc-protected amino acids in each step. The tripeptides 5 and 10 were used for the synthesis of 13-23, the derivatives of moronic acid (11) and morolic acid (12), to get a series of amide derivatives of the less frequently studied triterpenoids 11 and 12.

Nanodomains enriched in arachidonic acid promote P2Y12 receptor oligomerization in the platelet plasma membrane.

P2Y12 receptors on the platelet plasma membrane are targeted by several antiplatelets drugs. Although oligomerization and functioning of P2Y12 receptors depend on the membrane environment, little is known about their preferred membrane localization and the role of surrounding lipid composition, especially the arachidonic acids (ARA), which are abundant in platelets. Coarse-grained molecular dynamics simulations of platelet plasma membrane based on the lipidomics data were used to investigate the P2Y12 lipid environment and the involvement of ARA in its oligomerization in platelet plasma membranes.

The Drosophila RNA binding protein Hrp48 binds a specific RNA sequence of the msl-2 mRNA 3' UTR to regulate translation.

Repression of msl-2 mRNA translation is essential for viability of Drosophila melanogaster females to prevent hypertranscription of both X chromosomes. This translational control event is coordinated by the female-specific protein Sex-lethal (Sxl) which recruits the RNA binding proteins Unr and Hrp48 to the 3' untranslated region (UTR) of the msl-2 transcript and represses translation initiation. The mechanism exerted by Hrp48 during translation repression and its interaction with msl-2 are not well understood.
