On the Gaussian modulus of lipid membranes.

The Gaussian modulus is a crucial property that influences topological transformations in lipid membranes. However, unlike the bending modulus, estimating the Gaussian modulus has been particularly challenging due to the constraints imposed by the Gauss-Bonnet theorem. Despite this, various theoretical, computational, and experimental approaches have been developed to estimate the Gaussian modulus, though they are often complex, and analytical estimates remain rare.

Intravascular Lithotripsy for Coronary Artery Calcification: An Expert Review.

Coronary artery calcification is an impediment to percutaneous coronary interventions by obstructing the device pathway or stent deployment. To facilitate percutaneous coronary intervention in such complex lesions, high-pressure balloon dilations, atherectomy procedures, and specialty balloons are used but they all come with considerable limitations and periprocedural complications like dissection and perforation. To surpass these disadvantages, intravascular lithotripsy was introduced which acts by delivering high-pressure pulsatile sonic waves circumferentially thereby destroying the calcium deposits.

Nanofibrous Peptide Hydrogels Leveraging Histidine to Modulate pH-Responsive Supramolecular Assembly and Antibody Release.

In this work, we investigate the pH-responsive behavior of multidomain peptide (MDP) hydrogels containing histidine. Small-angle X-ray scattering confirmed that MDP nanofibers sequester nonpolar residues into a hydrophobic core surrounded by a shell of hydrophilic residues. MDPs with histidine on the hydrophilic face formed nanofibers at all pH values tested, but the morphology of the fibers was influenced by the protonation state and the location of histidine in the MDP sequence.

FT538, iPSC-derived NK cells, enhance AML cell killing when combined with chemotherapy.

Induced pluripotent stem cell (iPSC)-derived natural killer (NK) cells offer an opportunity for a standardized, off-the-shelf treatment with the potential to treat a wider population of acute myeloid leukaemia (AML) patients than the current standard of care. FT538 iPSC-NKs express a high-affinity, noncleavable CD16 to maximize antibody dependent cellular cytotoxicity, a CD38 knockout to improve metabolic fitness, and an IL-15/IL-15 receptor fusion preventing the need for cytokine administration, the main source of adverse effects in NK cell-based therapies. Here, we sought to evaluate the potential of FT538 iPSC-NKs as a therapy for AML through their effect on AML cell lines and primary AML cells.
